Please help me with 37 and 38 with the correct answer

Answer:

Daniel is rollerblading at 15 miles per hour

Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15

Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15

Answer:

[tex]y= 480-0.5x[/tex]

Step-by-step explanation:

Given data

Number of balls= 480

we are told that 50%(half) of the balls are put back every 1

let the number of hours be x

and let the remaining ball be y after x hours

Hence the expression is given as

[tex]y= 480-0.5x[/tex]

Answer:

The length of QS = 8

Step-by-step explanation:

From the above question:

Δ Q R S ≅ Δ T U V

Q S = 3 v + 2 , and T V = 7 v − 6 , enter the lengths of QS

Hence:

Step 1

We solve for v

QS = TV

3v + 2 = 7v - 6

Collect like ters

2 + 6 = 7v - 3v

8 = 4v

v = 8/4

v = 2

Step 2

Solving for Q S

Q S = 3 v + 2

v = 2

QS = 3(2) + 2

QS = 6 + 2

QS = 8

The length of QS = 8

it's JIL and HIL.

hope it helps :)

The angle ∠JIL and ∠HIL are supplementary angles. Then the correct option is D.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

HJ and KM are parallel lines. And NG interset the line HJ at I and KM at L.

Then the supplementary angles are given below.

Answer:

The value of [tex]\frac{1}{2}y[/tex] is -1

Step-by-step explanation:

Equations

We have the equation:

[tex]-3(y - 1) = 9[/tex]

It's required to find

[tex]\frac{1}{2}y[/tex]

Let's solve the equation. Dividing by -3:

[tex]y - 1 = \frac{9}{-3}= -3[/tex]

Adding 1:

[tex]y=-3+1=-2[/tex]

Since y=-2, then y/2=-1

The value of [tex]\frac{1}{2}y[/tex] is -1

UX is the midline,

ST is the leg,

VW is the other leg.

so,

Answer:

A. 27 degrees, 63 degrees, 90 degrees.

Step-by-step explanation:

Let the angle of the triangle be x

Given the following data;

3 : 7 : 10 = 3x : 7x : 10x

We know that the sum of the sides of a triangle is equal to 180 degrees.

3x + 7x + 10x = 180

20x = 180

x = 180/20

x = 9

For the first side;

3x = 3 × 9 = 27°

For the second side;

7x = 7 × 9 = 63°

For the third side;

10x = 10 × 9 = 90°

Therefore, the ratio of the angles of the triangle is 27° : 63° : 90°.

Answer:

The measure of the angles of a triangle are in the extended ratio of 3 : 7 : 10. Find the measures of the angles.

A. 27 degrees, 63 degrees, 90 degrees✓

B. 30 degrees, 60 degrees, 90 degrees

C. 30 degrees, 70 degrees, 100 degrees

D.33 degrees, 77 degrees, 80 degrees

Step-by-step explanation:

Let the required angles of the triangle be 3x, 7x and 10x

According to the above problem,

[tex]3x + 7x + 10x = 180 \\ 20x = 180 \\ x = \frac{180}{20} \\ \boxed{x = 9}[/tex]

Therefore the angles are :---

[tex]3x = 3 \times 9 = 27°✓ \\ 7x = 7 \times 9 = 63°✓ \\ 10x = 10 \times 9 = 90°✓[/tex]

Answer:

Option (3)

Step-by-step explanation:

Let the unknown angle of the triangle measure x°.

By applying cosine rule in the right triangle,

cos(x) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

cos(x) = [tex]\frac{33}{65}[/tex]

x = [tex]\text{cos}^{-1}(\frac{33}{65})[/tex]

x = 59.49°

  ≈ 60°

Therefore, option (3) will be the correct option.

Answer: 17 years

Step-by-step explanation:

City A is currently 2,425 people in number and growing at 27 per year.

An expression to find the population in a given year assuming the year is x would be:

= 2,425 + 27 * x

= 2,425 + 27x

Applying the same logic to City B would give an expression of:

= 1,813 + 63x

Equating these together will give the year they will be the same:

2,425 + 27x = 1,813 + 63x

2,425 - 1,813 = 63x - 27x

612 = 36x

x = 612/36

x = 17 years

Answer:

16

Step-by-step explanation:

let the smaller no be x so the greater no is 8 + x

soln

8+x + x = 40

8 + 2x = 40

2x = 40-8

2x = 32

x = 32÷2

therefore x = 16

Answer:

16 and 24

Step-by-step explanation:

let the 2 numbers be x and y, x > y , then

x + y = 40 → (1)

x = y + 8 → (2) [ greater number 8 more than smaller ]

Substitute x = y + 8 into (1)

y + 8 + y = 40, that is

2y + 8 = 40 ( subtract 8 from both sides )

2y = 32 ( divide both sides by 2 )

y = 16

Substitute y = 16 into (2)

x = 16 + 8 = 24

The 2 numbers are 16 and 24

Answer:

Runner 1 = 9th place

Runner 2 = 10th place

Runner 3 = 11th place

Runner 4 = 12th place

Runner 5 = 13th place

Step-by-step explanation:

Given that:

Number of runners = 5

Total points scored = 55

Finishing spot for each runner (they finished one after the other)

Hence,

x, (x + 1), (x + 2), (x + 3), (x + 4)

x + x + 1 + x + 2 + x + 3 + x + 4 = 55

5x + 10 = 55

5x = 55 - 10

5x = 45

x = 9

Hence,

Runner 1 = 9th place

Runner 2 = 10th place

Runner 3 = 11th place

Runner 4 = 12th place

Runner 5 = 13th place

Answer:

7y

Step-by-step explanation:

The answer for combine y and 7 are 7a, 7 +y, 7 - y and 7/y.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now the given statement is,

combine y and 7

Now a variable is a symbol (usually a letter) that stands for a value that may vary.

Here y is our variable.

When we combine numbers and variables in a valid way, using operations such as addition, subtraction, multiplication, division, exponentiation, and other operations and functions, the resulting combination of mathematical symbols is called a mathematical expression.

Thus, combining y and 7 may have result as-

7a, 7 +y, 7 - y and 7/y.

Thus, the answer for combine y and 7 are 7a, 7 +y, 7 - y and 7/y.
