It was 2 hours

A bicyclist ride 3 mph (miles per hour) to cover 12 miles in 4 hours

The distance of the first ride, ridden for 120 minutes at 18 mph, was 36 miles. To cover 12 miles in 4 hours, the bicyclist must ride at a speed of 3 mph.

To find the distance of the first ride, we can use the formula:

Distance = Speed × Time

Given that the bicyclist rides for 120 minutes (2 hours) at an average speed of 18 miles per hour:

Distance = 18 miles/hour × 2 hours = 36 miles

So, the distance of the first ride was 36 miles.

To find the speed the bicyclist must ride to cover 12 miles in 4 hours, we use the same formula:

Speed = Distance / Time

Given that the distance is 12 miles and the time is 4 hours:

Speed = 12 miles / 4 hours = 3 miles per hour

The bicyclist must ride at a speed of 3 miles per hour to cover 12 miles in 4 hours.

Answer:

y - 4 = -1/2(x+6).

Step-by-step explanation:

The equation of the line is: y - y0 = m(x-x0)

If the line passes through the points (x1, y1)=(-6, 4) and (x1, y1)=(2, 0). Then, the slope is:

[tex]m = \frac{y1-y0}{x1-x0} = \frac{0-4}{2-(-6)} = -\frac{1}{2} [/tex]

Then, the equation is: y - 4 = -1/2(x+6).

Answer: C.

Step-by-step explanation:

Diameter = Radius/2

So, the radius would be 6.5 in.

The formula for the volume of a sphere is: V = 4/3 (3.14) r^3.

So, once you "plug in" the radius, you get an equation of V = 4/3 (3.14) r^3.

And, once you solve the equation, you get and answer of 1,150 in.^3, rounded to the nearest cubic inch.

The volume of a sphere with a diameter of 13 inches, using the formula V = 4/3 * π * r³ and rounding off to the nearest cubic inch, is approximately 1151 cubic inches or choice C, 1150 in³.

To find the volume of a sphere, you can use the formula V = 4/3 * π * r³, where V is the volume and r is the radius. In this case, the diameter of the sphere is given as 13 inches. So, the radius would be half the diameter, which is 6.5 inches.

Plugging the values into the formula, we get V = 4/3 * 3.14 * (6.5)³. Calculating this gives an approximate value of 1151 cubic inches. Since we need to round to the nearest cubic inch, the final volume is 1151 in³.

So, the correct choice is C. 1150 in³.

Answer:

The diagonal is 39.54 in

Step-by-step explanation:

First we use the Pythagorean theorem to calculate the length of the diagonal of the base.

If the base measures 13 inches by 35 inches then the diagonal is:

[tex]c = \sqrt{13^2 +35^2}\\\\c= 37.34\ in[/tex]

Now we use the Pythagorean theorem again to find the diagonal of the cube.

If the height of the box is 13 inches and the diagonal of the base is 37.34 inches then the diagonal of the cube will be

[tex]z = \sqrt{37.34^2 +13^2}\\\\z= 39.54\ in[/tex]

The baton will fit in the box if it is placed in the direction of the diagonal of the cube, since:

39.54\ in > 38 inches

Using the 3D Pythagorean theorem, the diagonal of the box is calculated to be approximately 39.53 inches, which means that Kylie's 38-inch baton will fit inside the box diagonally.

Kylie needs to check if her 38-inch long baton will fit diagonally in a box with dimensions of 13 inches by 35 inches by 13 inches. To determine whether the baton will fit, she needs to find the length of the longest diagonal of the box. This is solved by using the 3D Pythagorean theorem, which is an extension of the traditional Pythagorean theorem applied to three dimensions.

To find the length of the diagonal (d), we use the formula:

d = √(l² + w² + h²)

Where l is the length, w is the width, and h is the height of the box. Substituting the given values:

d = √(13² + 35² + 13²)

d = √(169 + 1225 + 169)

d = √1563

d ≈ 39.53 inches

The calculated diagonal length of approximately 39.53 inches indicates that Kylie's baton, which measures 38 inches, will indeed fit inside the box diagonally.

Error question or wrong

The line in the middle has a right angle, so the angle just above the Y would be 90 degrees.

The angle to the right of y is given as 48.

The three inside angles of a triangle need to equal 180.

So y  = 180 - 90 - 48 = 42 degrees.

Answer:

Option B.

Step-by-step explanation:

The constant of proportionality is the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality.

Given that the graph is a straight line, we can find the constant of proporctionality just by selecting a point, and then dividing the y-value by the x-value.

We can see from the graph that when y=5, x=4. Then, the constant of proportionality comes to be:

k = 5/4 = 1.25.

Then, the correct option is Option B.

Answer:

C. 3Pi/2 or 270 degrees

Step-by-step explanation:

The first step is to ignore the negative sign and then evaluate the arcsin of 1 to obtain the reference angle of θ in the first quadrant;

θ = arcsin(1)

θ = 90 degrees or equivalently pi/2

Since the sine of θ was given as -1, this will imply that θ lies either in the third or forth quadrant where the sine of an angle is negative.

To obtain the value of θ in the third quadrant we simply add 180 degrees of pi radians to our reference angle;

90 + 180 = 270 degrees

pi/2 + pi = 3/2 pi

-10t+6=-44

The given expression is :

h(t)=-10t+6

We want to find the value of t that will evaluate to -44.

We equate the function to -44 and solve for t.

[tex]-10t+6 = - 44[/tex]

Subtract 6 from both sides of the equation,

[tex]-10t = - 44 - 6[/tex]

Answer:

900 miles

Step-by-step explanation:

Well, 200 miles is 1 inch. 100 miles is 1/2 an inch.

Answer:

900

Step-by-step explanation:

Given: 1/4 in. = 50 miles

Find the amount of miles per inch. Multiply 4 to both sides of the equation.

(1/4 in.) x (4) = (50 miles) x (4)

4/4 in. = 200 miles

1 in. = 200 miles

Now, find the amount of miles for 4 1/2 in. Multiply 4 1/2 to both sides.

Note that 4 1/2 = 4.5

(1 in.)(4.5) = (200 miles) x (4.5)

4.5 = 200 x 4.5

4.5 = 900

900 miles is your answer.

$22.75

Start by finding the cost of each topping. Subtract $17.50 minus $14.00 to find that adding 2 toppings costs $3.50. Now, divide $3.50 by 2 to find that the cost for adding only one topping is $1.75.

Then, multiply $1.75 by 5 to find how much it costs to add 5 toppings. You get $8.75.

Finally, add the cost of 5 toppings to the cost of a large pizza with no toppings. $14.00 plus $8.75 equals $22.75, so a large pizza with 5 toppings costs $22.75.

Answer: $22.75

Step-by-step explanation:

Given : The cost in dollars, y, of a large pizza with x toppings from Pat’s Pizzeria can be modeled by a linear function.

A linear function is given by :-

[tex]y=mx+c[/tex]                            (1)

, where m is slope (rate of change of y w.r.t x) and c is the y-intercept.

A large pizza with no toppings costs $14.00.

i.e. for x=0 , y= 14

Put theses values in (1) , we get

[tex]14=m(0)+c\\\Rightarrow\ c=14[/tex]   (2)

A large pizza with 2 toppings costs $17.50.

i.e. for x=2 , y= 17.50

Put theses values in (1) , we get

[tex]17.50=m(2)+c[/tex]      

Put value of c from (2)

[tex]17.50=2m+14\\\\[/tex]      

Subtract 14 from both sides , we get

[tex]3.50=2m[/tex]

Divide both sides by 2 , we get

[tex]1.75=m[/tex]

Put m= 1.75 and c= 14 in (1) , the linear function representing cost of large pizza becomes [tex]y=1.75x+14[/tex]

At x= 5

[tex]y=1.75(5)+14=8.75+14=22.75[/tex]

Thus , the cost of a pizza with 5 toppings= $22.75

p = 2 , q = 0

Step-by-step explanation:

Solve the following system:

{-28 = -14 p - 40 q | (equation 1)

10 q + 4 = 2 p | (equation 2)

Express the system in standard form:

{14 p + 40 q = 28 | (equation 1)

-(2 p) + 10 q = -4 | (equation 2)

Add 1/7 × (equation 1) to equation 2:

{14 p + 40 q = 28 | (equation 1)

0 p+(110 q)/7 = 0 | (equation 2)

Divide equation 1 by 2:

{7 p + 20 q = 14 | (equation 1)

0 p+(110 q)/7 = 0 | (equation 2)

Multiply equation 2 by 7/110:

{7 p + 20 q = 14 | (equation 1)

0 p+q = 0 | (equation 2)

Subtract 20 × (equation 2) from equation 1:

{7 p+0 q = 14 | (equation 1)

0 p+q = 0 | (equation 2)

Divide equation 1 by 7:

{p+0 q = 2 | (equation 1)

0 p+q = 0 | (equation 2)

Collect results:

Answer:

The money was invested for 16 years

Step-by-step explanation:

This is a compound interest problem and the following information has been provided;

Principal, P = 2500

Rate, r = 0.05 compounded semiannually. This will imply an effective rate of 0.05/2 = 0.025 effective per semiannual period.

Accumulated amount, A = 5509.39

We are required to determine the duration of investment in years. We let the number of years be n. We then use the compound interest formula;

[tex]A=P(1+r)^{n}\\\\5509.39=2500(1+0.025)^{2n}[/tex]

We raise to power 2n since there are 2n semiannual periods in n years. The next step is to divide both sides by 2500;

[tex]2.203756=1.025^{2n}\\[/tex]

We introduce logs in order to solve for n;

[tex]ln(2.203756)=2nln(1.025)\\\\2n=\frac{ln(2.203756)}{ln(1.025)}\\ \\2n=32\\\\n=16[/tex]

The expression (4y^6)^3 - (10z^2)^3 is equivalent to 64y^18 - 1000z^6.

Factor out common powers:

64y^18 = (2^6)(y^3)^6

1000z^6 = (10^3)(z^2)^3

Rewrite the expression with factored terms:

64y^18 - 1000z^6 = (2^6)(y^3)^6 - (10^3)(z^2)^3

Apply power of a power rule:

(a^m)^n = a^(mn)

(2^6)(y^3)^6 = 2^(66) * y^(36) = 2^36 * y^18

(10^3)(z^2)^3 = 10^(33) * z^(2*3) = 10^9 * z^6

Substitute back the simplified terms:

2^36 * y^18 - 10^9 * z^6 = (4y^6)^3 - (10z^2)^3

Therefore, (4y^6)^3 - (10z^2)^3 is the equivalent expression to 64y^18 - 1000z^6. Both expressions involve the difference of cubes of binomials, with one focusing on powers of 4y^6 and the other emphasizing powers of 10z^2.

For this case we have that by definition, the formula to count the total number of different permutations is:

[tex]nP_ {r} = \frac {n!} {(n-r)!}[/tex]

SUstituyendo:

[tex]n = 8\\r = 5[/tex]

We have:

[tex]8P_ {5} = \frac {8!} {(8-5)!} = \frac {8!} {3!} = \frac {8 * 7 * 6 * 5 * 4 * 3!} {3! } = 6720[/tex]

Answer:

p = - 6, p = - 2

Step-by-step explanation:

Given

- 2p² = 16p + 24

Subtract 16p + 24 from both sides

- 2p² - 16p - 24 = 0 ← in standard form ( divide all terms by - 2)

p² + 8p + 12 = 0

To factor the quadratic

Consider the factors of the constant term (+ 12) which sum to give the coefficient of the p- term (+ 8)

The factors are + 6 and + 2, since

6 × 2 = 12 and 6 + 2 = 8, thus

(p + 6)(p + 2) = 0

Equate each factor to zero and solve for p

p + 6 = 0 ⇒ p = - 6

p + 2 = 0 ⇒ p = - 2
