Plug in 6 for x and solve it.

Answer:

The y-intercept represents a temperature of 30°F when there are 0 cricket chirps.

The slope represents an additional 1 chirp for each addition 1.2°F increase in temperature.

If the number of chirps increases from 10 to 30, the temperature has increased by 24°F.

If the temperature increases from 30°F to 60°F, the number of chirps has increased by 25 chirps.

Step-by-step explanation:

The given equation of the line of best fit is y = 1.2x + 30.

This is in slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

Therefore, for the given equation:

The y-intercept is the point at which the graph intersects the y-axis, so the y-value when x = 0. Therefore:

The x-values represents the number of cricket chirps and the y-values represent the temperature in °F.

The slope tells us the rate of change of y relative to x, so the rate of change of the temperature to the number of cricket chirps.

1.2x means that for each increase of one x-value, the y-value increases by 1.2. Therefore:

To find the temperature when the number of chirps is 10, substitute x = 10 into the equation of the line and solve for y:

⇒ y = 1.2(10) + 30 = 42°F

To find the temperature when the number of chirps is 30, substitute x = 30 into the equation of the line and solve for y:

⇒ y = 1.2(30) + 30 = 66°F

Therefore, the difference in temperature is:

⇒ 66°F - 42°F = 24°F

Therefore,

To find the number of chirps when the temperature is 30°F, substitute y = 30 into the equation of the line and solve for x:

⇒ 1.2x + 30 = 30

⇒ 1.2x = 0

⇒ x = 0

To find the number of chirps when the temperature is 60°F, substitute y = 60 into the equation of the line and solve for x:

⇒ 1.2x + 30 = 60

⇒ 1.2x = 30

⇒ x = 25

The difference in the number of chirps is:

⇒ 25 - 0 = 25

Edge

The tip of the minute hand on a clock travels a distance of 4π inches in 15 minutes.

The distance traveled by the tip of a minute hand on a clock can be calculated using the circumference formula.

The circumference of a circle is given by the formula:

C = 2πr C is the circumference, π is pi (approximately 3.14159) and r is the radius.

The distance from the center of the clock to the tip of the minute hand is the radius is 8 centimeters.

The circumference of the circle traced by the tip of the minute hand is:

\(\text{C} = 2\pi \text{r}\)

\(= 2\pi (8)\)

\(= 16\pi \ \text{centimeters}\)

Since the minute hand travels the full circumference of the circle in 60 minutes, in 15 minutes it will cover 15/60 = 1/4 of the circumference.

The distance traveled by the tip of the minute hand in 15 minutes is:

\(\text{Distance} = \huge \text(\dfrac{1}{4}\huge \text) \times C\)

\(= \huge \text(\dfrac{1}{4}\huge \text) \times (16\pi)\)

\(= 4\pi \ \text{centimeters}\)

Answer:

4π cm ≈ 12.6 cm

Step-by-step explanation:

The clock can be modelled as a circle, where the radius (r) is equal to the length of the minute hand:  r = 8 cm.

A clock face is divided into 12 equal sectors (numbered 1 to 12).

It takes 60 minutes for the minute hand to complete one revolution of the clock. Therefore, each sector represents the passing of 5 minutes.

This means that 15 minutes equals 3 sectors, which is a quarter of the circle.

To find the distance the tip of the minute hand travels in 15 minutes, we need to find a quarter of the circumference of a circle with radius 8 cm.

The formula for the circumference of the circle is C = 2πr, where r is the radius. Therefore, the equation to find the distance the tip of the minute hand travelled in 15 minutes is:

\(\sf Distance=\dfrac{2 \cdot \pi \cdot 8}{4}\)

Simplifying, we get:

\(\sf Distance=\dfrac{16 \cdot \pi}{4}\)

\(\sf Distance=4 \pi\)

Therefore, the minute hand will travel 4π cm or approximately 12.6 cm (to the nearest tenth) in 15 minutes.

Answer:

11 whole meals

Step-by-step explanation:

Lets say that you have 800 noodles in one box. The serving size would be 80 noodles / meal. Then the question says you eat 7/8 of the recommended meal, which would be 70 noodles. When you divide 800 by 70, you get 11.4285714286 meals. Remember that the question is asking for full meals, so you round down to 11 full meals.

If you want a more algebraic answer:

10 servings (\(\frac{7/8}{1}\)) = 10 (8 / 7) = 80/7 = 11.4285714286 meals.

round down to 11 full meals.

11 complete meals can you get from one box.

Given that, a box of rotini noodles contains 10 servings.

If you eat 7/8 of the recommended serving as a meal, we need to find how many complete meals can you get from one box.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, whereas the whole can be any number, a specific value, or a thing.

Now, the number of complete meals=10÷7/8

=80/7

=11.42≈11

Therefore, 11 complete meals can you get from one box.

The equivalent expression 2/3 × 42 is 28. The equivalent expression 5/12 × 26 is \(10\frac{5}{6}\).

What is an equivalent expression?

Expressions that are similar in value or worth but differ in appearance are called equivalent expressions. At least two expressions are required to determine whether two expressions are equivalent. Equivalent expressions are used and required on numerous occasions in math. The distributive property makes it simple to write an expression without parentheses around it. Equivalent expressions are used frequently in algebra in mathematics.

Given numbers are 2/3 × 42 and 5/12 × 26.

Now simplify 2/3 × 42:

(2/3) × (42/1)

= (2×42)/(3×1)

= 2×14        [Divide denominator and numerator by 3]

=28

Now simplify 5/12 × 26:

(5/12) × (26/1)

= (5×26)/(12×1)

= (5×13)/(6×1)       [Divide denominator and numerator by 3]

In this case we have a translation of 8 units to the left and 11 units upwards.

To find the translation, we just need to compare the two known vertices before and after the translation.

If we have a translation of a units in the x-axis and b units in the y-axis, we will get:

T(a, b)L ---> L'

We know that L = (7, -3) and L' = (-1, 8)

Then we can write:

(7 + a, -3 + b) = (-1, 8)

Then we have two equations:

7 + a = -1 ---> a = -1 - 7 = -8

-3 + b = 8 ---> b = 8 + 3 = 11

Then we have a translation of 8 units to the left and 11 units up-.

The sales tax rate is 10.45 percent.

The area of the first room is 11 x 12 = 132 square feet and the area of the second room is 25 x 13 = 325 square feet.

The cost of the carpet and padding for the first room is 132 x (3.50 + 0.75) = $593.25 and for the second room is 325 x (3.50 + 0.75) = $1294.75.

The total cost of the carpet and padding (before tax) is $593.25 + $1294.75 + $500 = $2388.

Now we can set up an equation to solve for the sales tax. We know that the total cost with tax is $2637.63. So, the equation would be:

Total cost with tax = Total cost before tax + Tax

2637.63 = 2388 + Tax

Tax = 2637.63 - 2388

Tax = $249.63

To find the sales tax rate, we can divide the tax by the total cost before tax.

Tax Rate = Tax / Total cost before tax

Tax Rate = 249.63 / 2388 = 0.1045 or 10.45%

Therefore, the sales tax rate is 10.45 percent.
