How much NaBr solute is saturated at 70 degrees?
A.
110
B.
B.120

C.
130

D.
140

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:

This week sales = 26

Last week sales = 84

Step-by-step explanation:

Let this week sales = x

Sales last week = 6 + 3x

Sales last week + this week = 110

x + (6 + 3x) = 110

x + 6 + 3x = 110

6 + 4x = 110

4x = 110 - 6

4x = 104

x = 26

This week sales = 26

Last week sales = 6 + 3(26) = 84

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: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.

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:

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:

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
