Answer:

C . 4

Step-by-step explanation:

step 1 : -3 multiply with inside of the ( 7x-5 )

= -21x + 15

step 2 : then it will be 21x + 15 = 87 + 3x

step 3 : switch between the odds into like this

21x - 3x = 87 - 15

step 4 : subtract it all

18x = 72

step 5 : bring 18 to the other side

x = 72/18

step 6 : to find the ans of x is just calculate them

x = 72 ÷ 18

= 4

Or you can do like these ⬇️

-3 ( 7x - 15 ) = 87 + 3x

21x + 15 = 87 + 3x

21x - 3x = 87 - 15

18x = 72

x = 72/18 or 72÷18

x = 4

Answer:

1. Clear parentheses on both sides of the inequality and collect like terms.

2. Add or subtract terms so the variable is on one side and the constant is on the other side of the inequality sign.

3. Multiply and divide by whatever constants are attached to the variable.

Answer:

24.7 feet

Step-by-step explanation:

Maria who is 6 feet tall stands 20 feet away from the base of a tree she looks up at the top of the tree at a 43° angle of elevation.

what is the approximate height of the tree rounded to the nearest 10th?

We solve the above question using the Trigonometric function of Tangent

tan θ = Opposite/Adjacent

θ = Angle of elevation

Adjacent = Distance from the base of the tree = 20 feet

Opposite => Height of the tree = x

θ = 43°

tan 43 = x/ 20 feet

x = tan 43 × 20 feet

x = 18.650301723 feet

Approximately = 18.7 feet

We are told in the question that Maria is 6 feet tall

Therefore, the height of the tree = Maria's height + Height

= 6 feet + 18.7 feet

= 24.7 feet

Answer:

A. 27.3

B. 27.28

Step-by-step explanation:

You would have to round the tenth place up because of the 8 in the hundredths place, and for the hundredth place you would have to see if the thousandths place is higher than a 5 and if not don’t round up.

Answer:

a=27.3000

b=27.2800

Step-by-step explanation:

you just look at the decimal places and ignore the whole numbers for now the you look at the 2 since it is tenth the number at its back will add one to it because 8 is greater than 5 and it becomes 3 since we added 1 to 2 . our number then becomes 27.3 and the zeros you can remove them or put them it doesn't matter.

Answer:

19.2

Step-by-step explanation:

I hope it helps you.....

Answer:

AC ≈ 19.2 cm

Step-by-step explanation:

Using Pythagoras' identity in Δ BCD to find BC

BC² + BD² = DC² , that is

BC² + 12.6² = 19.3²

BC² + 158.76 = 372.49 ( subtract 158.76 from both sides )

BC² = 213.73 ( take the square root of both sides )

BC = [tex]\sqrt{213.73}[/tex] ≈ 14.62

Using the tangent ratio in Δ ABD to find AB

tan20° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AB}{BD}[/tex] = [tex]\frac{AB}{12.6}[/tex] ( multiply both sides by 12.6 )

12.6 × tan20° = AB , then

AB ≈ 4.59

Then

AC = AB + BC = 14.62 + 4.59 ≈ 19.2 cm ( to 1 dec. place )

Answer:17

Step-by-step explanation:

so i think it would be 17 as 5 is equivlent  to 8.33 percent of 60 which is the total amount of kids and 8.33 percent of 250 is 20 but since i think ur school rounds that percentage it would 17 red shirts

The results are in the table​ of the 250 total T-shirts about should be red 17.

We have given that,

Mr. torres ordered 250 School t-shirts to sell in a school store the t-shirts come in blue-gray or red to know how many of each color to order Mr. Torres polled a random sample of students. the results are in the table​.

A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.

So I think it would be 17 as 5 is equivalent to 8.33 percent of 60 which is the total amount of kids and 8.33 percent of 250 is 20 but since I think your school grounds that percentage it would be 17 red shirts.

Step-by-step explanation:

Answer:

A - 2 feet

Step-by-step explanation:

We know that the tank is a rectangular prism which means the volume is equal to length*width*depth

since the tank can hold 30 cubic feet of water, we can divide 30 by the given dimensions of the length and width to find the depth

30/5 = 6

6/3 = 2

therefore, the depth of the tank has to be 2 feet (A)

        Length x Width x Depth

From the question:

Volume of the rectangular prism = 30 cubic feet

Length of the rectangular prism = 5 feet

Width of the rectangular prism = 3 feet

Depth of the rectangular prism = ?

        Depth = Volume / (Length x Width)

Hence,

Depth = 30 cubic feet / 5 feet  x 3 feet

Depth = 30/ 15

Depth = 2 feet

The correct option is option A
