Selena rewrote the expression 4(5m + 12s) using the distributive property. What expression did Selena create?

Answer:

Step-by-step explanation:

Well if its a 8ft ladder and its being set 2ft off from the base i think the chimney is 6 ft tall cause 8-2 is 6...

The chimney measures approximately 7.75 feet tall.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

To find the height of the chimney, you can use the formula for the length of the hypotenuse of a right triangle, which is:

c² = a² + b²

Where c is the length of the hypotenuse (in this case, the length of the ladder), a is the length of one of the legs (in this case, the distance the ladder is set from the base of the chimney), and b is the length of the other leg (in this case, the height of the chimney).

Plugging in the values given in the question, we get:

8² = 2² + b²

64 = 4 + b²

b² = 64 - 4

b² = 60

b = √60

b = 7.745 ≈ 7.75  

Thus, the height of the chimney is approximately 7.75 feet.

a) 27

b) 9

c) 17.5

Step-by-step explanation:

a) 75% of 36 = 27

b) 36-27=9

c) 14*1.25=17.5

Answer:

2.56

Step-by-step explanation:

8* 32=256

256/100=2.56

Subtracting a negative is the same as adding a positive, since the negatives cancel each other out.

So, 7/8 - (-1/8) is the same as 7/8 + 1/8. Adding 1/8 to 7/8 gives you 8/8, or one whole, so your answer is D. 1!

Answer:

  2463.01 mm²

  2461.76 mm² if you use 3.14 for π

Step-by-step explanation:

The formula for the area of a circle is ...

  A = πr²

where r is the radius, half the diameter.

For a diameter of 56 mm, the radius is 28 mm. Using that in the formula gives an area of ...

  A = π(28 mm)² = 784π mm²

For an appropriate value of π, the area is ...

  784π mm² = 2463.00864... mm² ≈ 2463.01 mm²

For 3.14 as the value of π, the area is ...

  784(3.14) mm² = 2461.76 mm²

Comment on pi

Quite often these problems expect you to use 3.14 for pi. The required answer has 6 significant digits, so the use of a 3-digit value for pi is not appropriate. Rather, the value used should be 3.141493 or even more accurate.

Answer:

( I am assuming that these are all fractions)

1. 14 [tex]\frac{4}{7}[/tex]

2.  8

3. [tex]\frac{4}{15}[/tex]

4. 5 [tex]\frac{8}{11}[/tex]

Step-by-step explanation:

1. First you have to convert 15 into a fraction but it must have the same denominator causing the equation to look like 105/7 - 3/7= 102/7. But you cannot just leave the fraction like that it must be simplified 14 [tex]\frac{4}{7}[/tex]

2. Three-fifths of an hour is 36 minutes. You would next multiply 5 by 60 which would the hours into minutes 5 x 60 = 300. You would then divide 300 by 36 which would give you 8.3333333333, which I just simplified it to 8

3. In order for you to multiply a fraction you would first multiply the top then the bottom. 12 x 6= 72, 15 x 18= 270. The fraction would look like 72/270 which is simplified to [tex]\frac{4}{15}[/tex] .

4. First I changed the fractions into improper fractions causing the fraction to look like 36/8 x 14/11 (I got these answers by 8 by 4 then adding 4, then for the next fraction I multiplied 11 by 1 then added 3.) 36 x 14= 1224, 11 x 8= 88 the fraction would look like 1,224/88 you would simplify to 5 [tex]\frac{8}{11}[/tex]

Hope this helps

Please tell me if I made any mistakes I enjoy learning from them.

9 cm

Step-by-step explanation:

divide the total circle centimeter which is 18 in half. Half of 18 is 9 so the diameter is 9.

Answer:

R = 9 cm

Step-by-step explanation:

C = 2ПR

Also C = 18П сm

2ПR = 18П

R = 18П/2П = 9 сm

Answer:

it is the graph that is up to 10 on the y value and 15 on the x value

( on the second picture it is the first graph)

Step-by-step explanation:

In a family number of children 3

Charge for 1 child = $y per hour

Charge for 3 children = 3y

Charge for 1 Adult = $x per hour

Charge for 2 adults = 2x

If the family does not want to s[end more than $30 an hour at health club.

Where, x and y should be greater than 0.

make the graph of this inequality.

take equality of equation and then find x and y table.

2x+3y=30

 x        y

 0        10

 6        6

 15      0

we have to take a test point (0,0)

This statement is true. So, Graph will shade towards the test point (0,0)

Answer:

circumference: 37.7

area: 113.1

Step-by-step explanation:

for the future look up '___ of a circle'

and enter the radius (if u are given the diameter divide it by 2)

Answer:

circumference = 37.68 (37.7 if you're rounding it)

Area = 113.04 (113.1 if you're rounding it)

Step-by-step explanation:

The formula for circumference is C=2πr (2 times pi times radius)

If the diameter is 12, the radius is 6.

2 x 3.14 x 6 = 37.7

The formula for area is A=πr2 (pi x radius to the second power)

The radius is 6. Six to the second power is 36.

36 x 3.14 = 113.04

Here, the x-values are ...

  a) {2, 4, 6, 8} . . . no repeats, a function

  b) (0, 1, 1, 2} . . . 1 is repeated; not a function

  c) {3, 3, 4, 4} . . . 3 and 4 are repeated; not a function

  d) {1, 1, 2, 2} . . . 1 and 2 are repeated; not a function
