Find the missing angle.

Answers

Answer:

total angle of a triangle = 180°

other two angles = 85° , 65°

∴ the missing angle = 180 - ( 85 + 65 )

= 180 - 150

= 30

hope this answer helps you..

please mark as brainliest... thank you!

the missing angle is 30°. you add the other two and subtract it from 180° since a triangle is always 180°. hope this helps? can i please get brainliest?

Triangle NGM is reflected across the x-axis, and is dilated by a factor of
$2 \frac{1}{2} $

what are the coordinates of vertices N'G'M'

$Triangle NGM is reflected across the x-axis, and is dilated by a factor of [tex]2 \frac{1}{2} [/tex]what$

Answers

The coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

From the given graph, N(-4, 6), M(-6, 2) and G(-2, 4).

Scale factor = $2\frac{1}{2}$

= 2.5

The reflection of point (x, y) across the x-axis is (x, -y).

Here, N(-4, 6)→(-4, -6)

M(-6, 2)→(-6, -2)

G(-2, 4)→(-2, -4)

Now, with scale factor 2.5, we get

(-4, -6)→2.5(-4, -6)→N'(-10, -15)

(-6, -2)→2.5(-6, -2)→M'(-15, -5)

(-2, -4)→2.5(-2, -4)→G'(-5, -10)

Therefore, the coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

All faces of a bench except the two faces that rest on the ground will be coated with water-resistant paint. The bench is a right prism. What is the total area to be coated with the paint? Show your work.

Answers

Answer:

Step-by-step explanation:

234 is the answer

The total area to be painted is 8,316 square inches.

How to calculate total area?

The bench has a rectangular base with dimensions 63 in by 14 in. The height of the bench is 54 in. The two faces that rest on the ground do not need to be coated with paint, so the total area to be coated is the sum of the areas of the four remaining faces.

The area of one of the longer faces is:

63 in × 54 in = 3,402 in²

The area of the other longer face is the same, so the total area of the longer faces is:

2 × 3,402 in² = 6,804 in²

The area of one of the shorter faces is:

14 in × 54 in = 756 in²

The area of the other shorter face is the same, so the total area of the shorter faces is:

2 × 756 in² = 1,512 in²

The total area to be coated with paint is the sum of the areas of the four remaining faces:

6,804 in² + 1,512 in² = 8,316 in²

Therefore, the total area to be coated with paint is 8,316 square inches.

Answers

A. 1607.7

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

$\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}$

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

$\hrulefill$

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Mark is comparing prices of different brands before he goes shopping. Who has the best deal on ice cream? Brand Size & Price Turkey Hill $4.50 for 30 ounces Breyers $15.36 for 128 ounces Ben & Jerrys $2.88 for 16 ounces

Answers

Based on the given information, we need to calculate the price per ounce for each brand to determine the best deal on ice cream.

Turkey Hill: Price per ounce = 4.50 ÷ 30 = 0.15 dollars/ounce

Breyers: Price per ounce = 15.36 ÷ 128 = 0.12 dollars/ounce

Ben & Jerrys: Price per ounce = 2.88 ÷ 16 = 0.18 dollars/ounce

Therefore, the best deal on ice cream is Breyers, with a price of $0.12 per ounce.

Answer:

Breyers has the best deal, at $0.12/ounce.

Step-by-step explanation:

Convert all to the ice cream prices by the ounces in which they're sold to see how much the price is per 1 ounce:

4.5/30 = 0.15

15.36/128 = 0.12

2.88/16 = 0.18

Therefore, for 1 ounce of:

Turkey Hill: $0.15

Breyers: $0.12

Ben & Jerrys: $0.18

The sum of two numbers is 14 and their difference is 18. Find the larger number.

Answers

Answer:

Let a = the larger number and b = the smaller

a + b = 14

a - b = 18

We can add the 2 equations together.

2a = 32

2a/2 = 32/2

a = 16

The answer is 16
Because a = the larger number and b = the smaller number so equations would look like a+b=14 and a-b=18 we can add the 2 equations together and get 2a=32 then simply to 2a/2=32/2 then simplify that and get the answer a=16

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?

2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100

Answers

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

2 over 8 equals j over 18

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

2 over 8 equals j over 18

How to find the equation of linear regression?

To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator.

The points for this problem are given as follows:

(58, 52), (75, 66), (66, 68), (85, 74), (53, 38), (74, 65), (78, 76).

Inserting these points into a calculator, the equation is given as follows:

y = 1.05x - 10.43.

The estimated homework grade for a student with a test grade of 31 is x when y = 31, hence:

31 = 1.05x - 10.43

x = 41.43/1.05

x = 39.46.

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(4, 8) = 8. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 8 = 32. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - nine quarters minus eleven eighths is seven eighths.
