25 should be 3 square roots of 8, 4 square roots of 2, and then the square root of 50. 26 should be all those multiplyed together. First you need to reduce so, the square root of 28 will be 2 square roots of seven because you can pull out two twos. then the square root of 112 would be 4 square roots of seven. so when you multiply both of the 2 square roots of seven you get 28. so the rest is
28 x 2 x 3 x 4 square roots of 7. you cannot reduce the square anymore so the answer will be 672 square roots of 7. (28 x 2 x 3 x 4= 672)

Answer:

174

Step-by-step explanation:

Given

132, 145, 97, 112, 128, 82

Required

Estimate amount of students in an art class

This is calculated by obtaining the mean of the given data

$Mean = \frac{\sum x}{n}$

Where n is the number of observations

So; n = 6

$Mean = \frac{132+ 145+ 97+ 112+ 128+ 82}{6}$

$Mean = \frac{696}{6}$

$Mean = 174.0$

Hence, the estimated number of students is 174

A baker made 20 pies. a boy scout troop buys one–fourth of his pies, a preschool teacher buys one–third of his pies, and a cater

aleksklad [387]

One-fourth + one-sixth + one-third

three plus two plus four /12 = 9/12 = 3/4 

So, balance = 1/4 = 1/4 times 20 = 5 pies which is the answer!

Hope this helps!! Pleaseeee, Hit that Thanks button ;D

A pipe is leaking at 1.5 cups per day. About how many gallons per week is the pipe leaking?

Lubov Fominskaja [6]

1.5 cups x 7 days = 10.5 cups

(be ready, thisl come out ugly)

1 cup = 0.0625 gal

10.5 cups = 0.65625 gallons leaked per week

A line goes through the points (8,9) and (-2,4).

Softa [21]

Part A:

Slope of line is given by vertical distance ÷ horizontal distance

Let (8, 9) be (x₁, y₂) and (-2, 4) be (x₂, y₂)
The vertical distance is y₂ - y₁ = 4 - 9 = -5
The horizontal distance is x₂ - x₁ = -2 - 8 = -10

slope of the line = -5 ÷ -10 = 0.5
---------------------------------------------------------------------------------------------------------------

Part B

The point-slope form is given by
(y - y₁) = m (x - x₁)

We have the gradient, m = 0.5
(x₁, y₁) = (8, 9) ⇒ You can also use the other coordinate (-2, 4)
Substitute these value into the form, we have

(y - 9) = 0.5 (x - 8)
----------------------------------------------------------------------------------------------------------------

Part C

The slope-intercept form is given by the equation
y = mx + c

Where m is the slope gradient and c is the point where the line intercepts the y-axis. We don't have the value of c at the moment but we can find out by simplifying the equation in part B

y - 9 = 0.5 (x - 8) ⇒ Multiplying out the bracket
y - 9 = 0.5x - 4
y = 0.5x - 4 + 9
y = 0.5x + 5 ⇒ This the slope-intercept form

I’ll give 15. What is the missing side length in the triangle below?

Dmitry [639]

Answer:

40 ft

Step-by-step explanation:

The fiagram shows the right triangle (one angle is right angle).

By the Pythagorean theorem,

$\text{Leg}_1^2+\text{Leg}_2^2=\text{Hypotenuse}^2$
