Answer:

20

Step-by-step explanation:

We know that 10² = 100, so all integers above 100 have a square root greater than 10. Similarly, 11² = 121, so all integers below 121 have a square root less than 11. So, we want the integers from 101 through 120, inclusive. There are  integers from  through (just as there are 20 integers from 1 through 20).

Answer:

Step-by-step explanation:

To find the probability that Roy picks a chocolate flavor at random, we need to use the basic probability formula:
\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} \]
In this scenario:
- The favorable outcomes are the number of chocolate flavors.
- The total number of possible outcomes is the total number of flavors.
According to the given situation, there are a total of 16 flavors of ice cream, and out of these, 6 flavors contain chocolate.
Using the probability formula:
\[ \text{Probability of picking a chocolate flavor} = \frac{6}{16} \]
To simplify the fraction, we can divide both the numerator and the denominator by the greatest common divisor, which in this case is 2:
\[ \frac{6 \div 2}{16 \div 2} = \frac{3}{8} \]
Now, to express this as a decimal, we divide 3 by 8:
\[ 3 \div 8 = 0.375 \]
Therefore, the probability that Roy picks a chocolate flavor at random is 0.375. If you're looking at multiple-choice answers, you would choose the option that best fits this answer.

Answer:

Joey must get a score of 94 to have a average test score of 90.

Step-by-step explanation:

Joey wants a average score of 90.

He already scored 91 and 85 on the previous two tests, and wants to know the score to get a 90 as an average.

Set the equation:

Average = (score of known tests + x)/(amount of tests in all).

Note that: x = score of the next test.

First, Plug in the corresponding numbers to the corresponding terms/variables:

90 = (91 + 85 + x)/(3)

Simplify. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, multiply 3 to both sides:

90(3) = (91 + 85 + x)/(3) * 3

270 = 91 + 85 + x

Isolate the variable x. Combine like terms:

270 = (91 + 85) + x

270 = 176 + x

Subtract 176 from both sides:

270 (-176) = 176 (-176) + x

x = 270 - 176

x = 94

Joey must get a score of 94 to have a average test score of 90.

The expression for how both booths will cost for the same number of days (d) is 150 + 12d

Step-by-step explanation:

A company set up a food booth and a game booth at a county fair

We need to write an expression for how both booths will cost for the same number of days

Assume that the number of days is d for both booths

∵ The fee for the food booth is $100 + 5 dollars per day

∵ It used for d days

∴ The cost of the food booth = 100 + 5(d) ⇒ (1)

∵ The fee for the game booth is $50 + 7 dollars per day

∵ It used for d days

∴ The cost of the game booth = 50 + 7(d) ⇒ (2)

To find the cost for both booths in d days add (1) and (2)

∵ The cost for both booths = 100 + 5d + 50 + 7d

- Add the like terms

∴ The cost for both booths = (100 + 50) + (5d + 7d)

∴ The cost for both booths = 150 + 12d

The expression for how both booths will cost for the same number of days (d) is 150 + 12d

Final answer:

Malory catches up to Dori 25 minutes after starting her walk. Since Malory started at 12:20 pm, she catches up to Dori at 12:45 pm by walking at a faster pace.

Explanation:

To determine what time Malory caught up to Dori, we can set up an equation based on the distance each has traveled. Since distance equals speed multiplied by time, and steps per minute can be considered as speed, we need to find a point at which they have both covered the same distance.

Dori started walking at 12:00 pm and Malory started at 12:20 pm, so Malory starts walking 20 minutes later. We'll use t to represent the time in minutes that Malory has been walking when she catches up to Dori.

Thus, Dori has been walking for t + 20 minutes by the time Malory catches up.

We set up the following equation to find t:
Dori's distance = Malory's distance
50 steps/minute × (t + 20) = 90 steps/minute × t

Solving for t gives us:
50t + 1000 = 90t
1000 = 40t
t = 25 minutes

Therefore, Malory catches up to Dori 25 minutes after Malory started walking. Since Malory started walking at 12:20 pm, we add 25 minutes to this time to find out the catch up time is 12:45 pm.

Answer: 21

Step-by-step explanation:

If kamari loses 3 points for 1 question. How many would he lose for 7 questions. So basically, you times 3 points by 7 questions to get 21

Kamari's score decreases by 21 points due to 7 wrong answers.

To determine the change in Kamari's score, we need to calculate the total number of points he loses for the 7 wrong answers. Since he loses 3 points for each wrong answer, we multiply the number of wrong answers by the points lost per wrong

Number of wrong answers = 7

Points lost per wrong answer = 3

Total points lost = Number of wrong answers — Points lost per wrong answer

Total points lost = 7 — 3

Total points lost = 21

Therefore, Kamari's score decreases by 21 points.

Answer: 1/2

Step-by-step explanation: When dividing integers, if the signs are the same, the quotient is positive. So a negative divided by a negative always equals a positive. In this problem -3 ÷ -6 is 0.5.

However, there is no 0.5 on the list so we need to write the decimal as a fraction.

To write the decimal 0.5 as a fraction, we use the place value chart. 0.5 means 0 units and 5 tenths which can be written as the fraction 5/10.

Notice however that 5/10 is not in lowest terms so we need to divide the numerator and denominator by the greatest common factor of 5 and 10 which is 5 to get the equivalent fraction 1/2.

The range of (u circle v) (x) is (negative infinity, 0).

To find the range of (u circle v) (x), we need to substitute v(x) into u(x), which means replacing x in u(x) with v(x).

u(x) = -2x²

So, (u circle v) (x) = -2(v(x))² = -2(1/x)² = -2/x²

The range of (u circle v) (x) is (negative infinity, 0) because as x approaches 0 from the right, (-2/x²) approaches negative infinity, and as x approaches 0 from the left, (-2/x²) approaches positive infinity.

Answer:

1 : 80,000,000

Step-by-step explanation:

Convert each 12,000km to cm to match the model's unit:

12,000 * 100,000 = 1,200,000,000 cm

The scale is the ratio of the model's dimension to the planet's dimension:

15 : 1,200,000,000

Divide each by 15 to simplify the ratio:

1 : 80,000,000

Therefore, the model is at a scale of 1 : 80,000,000.

Final answer:

Will would have saved approximately $9,420.12 in 10 years by contributing 9% of his $41,000 salary annually, with a 3% employer match and a 7.13% interest rate.

Explanation:

To calculate how much Will would have saved in 10 years, we need to consider both his salary contribution and the employer's matching contribution. Will saves 9% of his $41,000 salary every year, which comes out to $3,690. The employer matches his contribution up to 3%, so the employer would contribute an additional $1,230 (3% of $41,000) every year.

To calculate the total savings after 10 years, we can use the formula for compound interest: A = P(1 + r/n)^(nt). In this case, the principal P is the total annual contributions, the interest rate r is 7.13%, and n is the number of times interest is compounded per year, which we will assume to be once per year.

Using the formula, we can calculate:

A = ($3,690 + $1,230)(1 + 0.0713/1)^(1*10)

A = $5,920 * 1.0713^10

A = $9,420.123296

Rounding to the nearest cent, Will would have saved approximately $9,420.12 in 10 years.

Answer: The graph is attached.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope and "b" is the y-intercept.

Given the first equation:

[tex]y=- 6x - 2[/tex]

You can identify that:

[tex]m=-6\\b=-2[/tex]

 By definition, the line intersects the x-axis when [tex]y=0[/tex]. Then, subsituting this value into the equation and solving for "x", you get that the x-intercept is:

[tex]0=- 6x - 2\\\\2=-6x\\\\x=-\frac{1}{3}\\\\x=-0.333[/tex]

Now you can graph it.

Solve for "y" from the second equation:

[tex]y +2=- 6x\\\\y=-6x-2[/tex]

 You can identify that:

[tex]m=-6\\b=-2[/tex]

Notice that the slopes and the y-intercepts of the first line and the second line are equal; this means that they are exactly the same line and the System of equations  has Infinitely many solutions.

See the graph attached.

Answer:

22.5%

Step-by-step explanation:

1 person is doing 0.025 of the work. What is that in percent??

We convert decimal to percentage by multiplying by 100 and sticking the "%" sign.

So,

0.025 * 100 = 2.5%

Hence, 1 person is doing 2.5% of the total 25% of the work alloted to 4 persons.

The other 3 would do rest of the work, that would be:

25% - 2.5% = 22.5%  of the work (rest 3 person would be)

Step-by-step explanation:

An inscribed angle is the angle with vertex and two endpoints lying on the circle.

1) This option shows an inscribed angle, because vertex A and endpoints B ans C lie on the circle.

2) This option doesn't show an inscribed angle, because vertex K doesn't lie on the circle.

3) This option shows an inscribed angle, because vertex X and endpoints V ans W lie on the circle.

4) This option doesn't show an inscribed angle, because vertex M doesn't lie on the circle.

5) Angle CAB is inscribed angle subtended on the arc BC with measure of 80°, so its measure is 40° (half of the measure of arc BC)

6) Angle WXV is inscribed in the circle and subtended on the arc WV. Hence, the measure of the arc WV is twice the measure of angle VXW and is equal to 84°.

Options 7) and 8) are not visible.

$4266.67 is deducted every month for income tax.

Step-by-step explanation:

Given,

Amount earned per year = $200,000

Income tax = 25.6%

Amount of income tax = 25.6% of amount earned

Amount of income tax = [tex]\frac{25.6}{100}*200000 = \frac{5120000}{100}[/tex]

Amount of income tax = $51200

As this amount is yearly, therefore, we will divide it by 12 to find monthly amount.

Income tax deducted per month = [tex]\frac{51200}{12}=\$4266.67[/tex]

$4266.67 is deducted every month for income tax.
