Answer:

a³ - 5a² + 4a + 5

Step-by-step explanation:

To solve this, remove the parentheses.  If you were subtracting the two phrases, you would distribute the negative sign to the second phrase, but you are adding so you will not have to do this

4a - a³ - 3 + 2a³ - 5a² + 8

a³ - 5a² + 4a + 5

Answer: 6.4 In decimal form.  32/5 in fraction form.

Step-by-step explanation:

So first times 8 by 12 which is 96

then, 3 times 5 which is 15

Simplify to 32/5

Answer: 32/5

Step-by-step explanation: When multiplying two fractions together, remember that we can cross-cancel.

In this problem the 12 and 3 reduce to 4 and 1.

So we have 8/1 · 4/5.

Next we simply multiply across the numerators and multiply across the denominators and we have our answer which is 32/5.

Answer:

90 squared is 8,100, and 120 squared is 14,400. So to figure out what c is you do 90^2 + 120^2 = Square Root of 22,500 which is 150.

So c = 150

Step-by-step explanation:

So C=150

hope this helps :D

By using the Pythagorean theorem, we will see that side C measures 150ft.

We can see that side C is the hypotenuse of a right triangle. We know both catheti of said triangle, then we can use the Pythagorean theorem.

It says that the sum of the squares of the cathetus is equal to the square of the hypotenuse. Then we have:

A^2 + B^2  = C^2

We know that:

A = 90ft

B = 120ft

Replacing that we get:

√((90ft)^2 + (120ft)^2) = C = 150ft

Then we conclude that side C measures 150ft.

Answer:

3x+2y=34

Step-by-step explanation:

L1: 2x-3y=12 => the slope m1=-2/(-3)=2/3

L2 perpendicular to L1 => m2= -1/m1=  -3/2

the point A(8,5) ∈ L2

=> y–yA=m2(x–xA)

L2: y-5=-3/2 *(x-8)

L2: 2y-10=-3x+24

Answer:

69 weeks

Step-by-step explanation:

Let the number of weeks be x.

The first tank holds 621 gallons is leaking at a rate of 4 gallons per week. This means that after x weeks, the amount of water in the tank is:

621 - 4x

The second tank holds 828 gallons is leaking at a rate of 7 gallons per week. This means that after x weeks, the amount of water in the tank is:

828 - 7x

After a certain amount of weeks, the amount of water in both tanks is the same. That means that:

621 - 4x = 828 - 7x

=> 7x - 4x = 828 - 621

3x = 207

x = 207 / 3 = 69

This means that the amount of water in the tank will be the same after 69 weeks.

Answer: x=3 and x=6

Step-by-step explanation:

Put the first equation in math-way and find the roots/zeros

An icicle drips at a rate that can be represented by the function

[tex]f(x) = -x^2 + 9x - 18[/tex], where 0 ≤ x ≤ 10 and x is the number of hours after the sun has risen. So, The solution are x = 3 and x = 6.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

An icicle drips at a rate that can be represented by the function

[tex]f(x) = -x^2 + 9x - 18[/tex],

where 0 ≤ x ≤ 10 and x is the number of hours after the sun has risen.

First, we have to find its solution since it is a quadratic function;

[tex]f(x) = -x^2 + 9x - 18\\\\f(x) = -x^2 + 3x+ 6x - 18\\\\f(x) = x (3-x) - 6(3-x)\\\\f(x) = (3-x)(x-6)[/tex]

So, The solution are x = 3 and x = 6.

Final answer:

To simplify the expression −5x + 8y + 2x − 3y, combine like terms, resulting in −3x + 5y.

Explanation:

To simplify the expression −5x + 8y + 2x − 3y, you want to combine like terms. The like terms are those with the same variable raised to the same power. In this expression, −5x and 2x are like terms, as are 8y and −3y.

Combine −5x and 2x: (−5 + 2)x = −3x

Combine 8y and −3y: (8 − 3)y = 5y

After combining like terms, the simplified expression is −3x + 5y.

Answer:

See below.

Step-by-step explanation:

ABC is an isosceles triangle with BA = BC.

That makes angles A and C congruent.

ABD is an isosceles triangle with AB = AD.

That makes angles ABD and ADB congruent.

Since m<ABD = 72 deg, then m<ADB = 72 deg.

Angles ADB and CDB are a linear pair which makes them supplementary.

m<ADB + m<BDC = 180 deg

72 deg + m<BDC = 180 deg

m<CDB = 108 deg

In triangle ABD, the sum of the measures of the angles is 180 deg.

m<A + m<ADB + m<ABD = 180 deg

m<A + 72 deg + 72 deg = 180 deg

m<A = 36 deg

m<C = 36 deg

In triangle BCD, the sum of the measures of the angles is 180 deg.

m<CBD + m<C + m<BDC = 180 deg

m<CBD + 36 deg + 108 deg = 180 deg

m<CBD = 36 deg

In triangle CBD, angles C and CBD measure 36 deg making them congruent.

Opposite sides DB and DC are congruent making triangle BCD isosceles.

The measure of ∠ABC  is 85 degrees from intersecting chords theorem.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

We have to find the measure of ∠ABC.

The intersecting chords theorem is a statement in elementary geometry that describes a relation of the four line segments created by two intersecting chords within a circle.

∠ABC  = 1/2 (130+40)

∠ABC  = 1/2(170)

Divide 170 by 2

∠ABC  = 85 degrees.

Hence, the measure of ∠ABC  is 85 degrees from intersecting chords theorem.

Answer:

6% sales tax

Step-by-step explanation:

48 / 800 = x / 100

What did you do to turn 800 into 100? Divide by 8.

Since we divided the denominator by 8, we also divide the numerator by 8.

48 / 8 = 6

6% sales tax

Final answer:

The percent of the sales tax on an $800 laptop computer with a $48 sales tax is 6%. This is found by dividing the sales tax by the cost of the computer and then multiplying by 100.

Explanation:

To calculate the percent of the sales tax for the laptop computer, you need to follow these steps:

Convert the sales tax amount to a decimal by dividing the sales tax by the cost of the item before tax.

For example: $48 (sales tax) ÷ $800 (cost of the laptop) = 0.06.

Then, convert the decimal to a percentage by multiplying it by 100.

Continuing the example: 0.06 × 100 = 6%.

Therefore, the sales tax rate for the laptop computer is 6%.

Answer:

$96

Step-by-step explanation:

First, let's find the price for a ticket with the markup.

Normally, you pay for 100% of the ticket price, but now you also have to pay an extra 20% of the ticket price.

100%+20%=120%

So, you are basically paying for 120% of the normal ticket price, $16

Multiply 120% and $16

120%*16

Convert 120% to a decimal by dividing by 100, or moving the decimal place 2 spots to the left

120%/100=1.20

120.0-->12.0-->1.20

1.20*16=19.2

Now, each adult ticket costs $19.20

Next, find how much 5 tickets will cost.

Multiply 5 and $19.20

5*19.20=96

5 adults will pay $96 with the ticket markup

We have been an image of a triangular pyramid. We are asked to find the volume of the given pyramid.

We know that volume of triangular pyramid is [tex]\frac{1}{3}b\cdot h[/tex], where,

b = Base area,

h = Height of pyramid.

We can see that base of pyramid a right triangle.

[tex]\text{Area of triangle}=\frac{1}{2}\times\text{Base}\times\text{Height}[/tex]

Now we will find height of base triangle using Pythagoras theorem.

[tex]h^2=30^2-24^2[/tex]

[tex]h^2=900-576[/tex]

[tex]h^2=324[/tex]

[tex]\sqrt{h^2}=\sqrt{324}[/tex]

[tex]h=18[/tex]

[tex]\text{Area of base triangle}=\frac{1}{2}\times24\times 18[/tex]

[tex]\text{Area of base triangle}=12\times 18[/tex]

[tex]\text{Area of base triangle}=216[/tex]

[tex]\text{Volume of triangular prism}=\frac{1}{3}b\cdot h[/tex]

[tex]\text{Volume of triangular prism}=\frac{1}{3}\cdot 216\cdot 30[/tex]

[tex]\text{Volume of triangular prism}=216\cdot 10[/tex]

[tex]\text{Volume of triangular prism}=2160[/tex]

Therefore, the volume of the given prism is [tex]2160\text{ m}^3[/tex] and option B is the correct choice.
