- remember that the midline is always half of the sum of the other two legs.

here,

UX is the midline,

ST is the leg,

VW is the other leg.

so,

ST + VW = 2UX

now plug in,

25 + VW = 2(35)

25 + VW = 70

VW = 45

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: 7 -1/6

Step-by-step explanation:

Multiply the denominator and numerator (1/3) by 2 to get 2/6, then do 1/6-2/6, which gives you a negative. Then subtract your whole numbers (14-7) to get 7 -1/6

Answer:

Step-by-step explanation:

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:

6.375 tons or 6 3/8 tons

Step-by-step explanation:

According to Given data, calculation are as follows,

Sunburst pebbles = 2 1/2 tons or 2.5 tons

Black polished pebble = 3 1/4 tons or 3.25 tons

River pebble = 5/8 tons or o.625 ton

So, total weight of pebbles are as follows,

Total weight = 2.5 tons + 3.25 tons + 0.625 ton

= 6.375 tons or 6 3/8 tons

Hence, total weight of pebbles was 6 3/8 tons.

[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

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.

Step-by-step explanation:

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

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
