i need answers quick thanks

Step-by-step explanation:

the small and the large triangles are similar triangles.

they have the same angles. and the corresponding sides correlate to each other with the same ratio for every pair of sides.

so,

28 / 82 = (2x + 8) / ((2x + 8) + (5x -4)) =

= (2x + 8) / (7x + 4)

(7x + 4)×28 = (2x + 8)×82

196x + 112 = 164x + 656

32x = 544

x = 17

Answer:

it is quite simple it's just that you need to substitute the input in place of x

eg:if the input is 2 then 2(3(2)+4) = 20 and 20 is the output

Step-by-step explanation:

they are on the same line, so they sum up to 180°

Answer:

a = -3 and b=5

Step-by-step explanation:

Given that 10 can be written as 2*5 or √2*√2*5, and √18 can be written as √(2*9) or √2*√9 or 3√2, you can write the fraction as:

[tex]\frac{5\cdot\sqrt2\cdot\sqrt2-3\sqrt2}{\sqrt2}[/tex]

So getting rid of the √2 factor, you get 5√2 - 3, so a=-3 and b=5

Answer: 334

Step-by-step explanation:

Cut the polygon into 2 pieces

Find the area of each rectangle and some it

7*10 = 70

24*(21-10) = 264

264 + 70 = 334

Answer:

334 ft²

Step-by-step explanation:

split the polygon into two

Area of A = 21 ft × 7 ft = 147 ft²

Area of B = (21 ft - 10 ft) × (24 ft - 7 ft)

Area of B = 11 ft × 17 ft = 187 ft²

Area of polygon = sum of Areas of A and B

147 ft² + 187 ft² = 334 ft²

The line four times the sum of 3.2 and a number is the number less 1.4 can be expressed as 4(n+3.2) = n-1.4.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given to us

Four times the sum of 3.2 and a number is the number less than 1.4

Let the number be n.

It is given that the sum of 3.2 and number,

n + 3.2

Four times the sum, therefore,

4(n+3.2)

The total we got is the number less 1. 4. thus,

4(n+3.2) = n - 1.4

Hence, the line four times the sum of 3.2 and a number is the number less 1.4 can be expressed as 4(n+3.2) = n-1.4.

took the quiz made a 100

The number of three-point tries is 36.

Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).

The first step is to determine the total number of tries and baskets: (27 X 7)/3 = 63

Number of three-point tries = (4/7) x 63 = 36

Answer:

Step-by-step explanation:

it looks like  an isosceles triangle, 2 equal side and 2 equal angles (F&E)

the sum of the interior angles in a triangle is 180°, and FH is 180°.

180 - 120 = 60° (angle G)

now we know that it is an equilateral triangle, so Y and 2x are 60°

(3 * 60 = 180°)

-------------------------------

or

180 - 60 = 120

120 : 2 = 60°

Answer:

38 or 36 if there's options

Step-by-step explanation:

Answer:

36

Step-by-step explanation:

By the Fundamental Counting Principle, if there are x ways to choose one thing, y ways to choose another thing, and z ways to choose another thing, then there are x*y*z possible combinations of all of those things.

Here, there are 3 ways to choose a shift, 4 ways to choose a pair of pants, and 3 ways to choose a tie. Therefore, there are 3*4*3 = 36 different outfits that Gerald can make that include one shirt, pair of pants, and tie.

Answer:

31° , 62° , 113° , 154°

Step-by-step explanation:

sum the 4 angles and equate to 360

y + 2y + 3y + 20 + 4y + 30 = 360 , that is

10y + 50 = 360 ( subtract 50 from both sides )

10y = 310 ( divide both sides by 10 )

y = 31

2y = 2(31) = 62

3y + 20 = 3(31) + 20 = 93 + 20 = 113

4y + 30 = 4(31) + 30 = 124 + 30 = 154

the 4 angles are 31° , 62° , 113° , 154°

Answer:

You divide 15 by 25 and you get your decimal, which you multiply by 100 to get your percent.

An exterior angle is equal to the sum of the two opposite inside angles:

x = 133 - 118 = 15 degrees

Answer: x = 15

Answer:

15 because 133=x-118 I hope it helps

The blood pressure of Ruby is modelled by following sinusoidal equation: [tex]y = 103 +18\cdot \sin (146\pi\cdot t)[/tex].

Answer:

D. -1/2

Step-by-step explanation:

First to rewrite the equation in numbers

[tex]125=\frac{1}{25}^{y-1}[/tex]

First, we need to find what exponent would get 1/25 to 125.

[tex]\frac{1}{25}^{y}=125[/tex]

Sense 1/25 is a fraction we must use a negative exponent to make it a whole number. We can just find what exponent would get 25 to 125 then make it negative. 1 wouldn't be enough and 2 would be too much so y is between 1 and 2 into negative is between -1 and -2. Sense the original equation has (y-1) the only option you can subtract 1 from to get between -1 and -2 is -1/2 which would give -1 1/2.

Answer:

Keep it simple: D or -1/2

Step-by-step explanation:

The absolute distance of the Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.

Mean is simply defined as the average of the given set of numbers. The mean is considered as one of the measures of central tendencies in statistics. The mean is said to be an arithmetic mean. It is the ratio of the sum of the observation to the total number of observations.

Mean refers to the average of the observation and deviation means the variation from the present standard.

Given

Robin’s scores: 99, 108, 102, 107, 119

Mean = 107

MAD = 5.2

Evelyn’s scores: 125, 137, 138, 145, 145

Mean = 138

MAD = 5.6

The absolute distance of the Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.

Hey there!

2(x + y)

DISTRIBUTE 2 WITHIN the PARENTHESES
