I need help solving for Y

Answers

Answer:

y=24

Step-by-step explanation:

since the triangles are similar, their sides are all in proportion

meaning:

[tex] \frac{20}{15} = \frac{32}{y} [/tex]

simplify the fraction

[tex] \frac{4}{3} = \frac{32}{y} [/tex]

cross multiply once the fraction is simplified

[tex]96 = 4y[/tex]

y=24

Answer:

y = 24

Step-by-step explanation:

the first triangle 20 : x : 32

the 2nd triangle 15 : 21 : y

Solve the equation of two triangles by similarity

x = [tex]\frac{21 * 20}{15}[/tex] = 28

y = [tex]\frac{21 * 32}{28}[/tex] = 24

​The pair of points (5, 6) and (10, y) lie on a line with slope 4/5 . What is the value of y?​

Answers

If the pair of points (5, 6) and (10, y) lie on a line with slope 4/5, then the value of y is 10

The slope m of the line passing through the points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is calculated as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

For the line passing through points (5, 6) and (10, y)

[tex]x_1=5, y_1=6, x_2=10, y_2=y[/tex]

The slope, m = 4/5

Substitute these value into the slope formula and solve for y

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\\frac{4}{5}=\frac{y-6}{10-5} \\\\\frac{4}{5}=\frac{y-6}{5}[/tex]

Cross  multiply:

4(5)  =  5(y-6)

4   =  y  -  6

Collect like terms

y  =  4  +  6

y  =  10

a water tank can hold up 80 gallons of water. if it is 40% full now. how many gallons of water does the tank contain?

Answers

Answer:

32 gallons of water

Step-by-step explanation:

If the total tank can hold up to 80 gallons of water, it is considered full when it contains 80 gallons. When the tank is 40% full, it has 40% of 80 gallons in the tank. 40% of 80 is 40/100*80=8*4=32 gallons of water.

To make I a subject of the formula V = IR, we *

multiply both sides by R
divide both sides by R
divide both sides by I

Answers

The original

Equation is V = IR

Where I is multiplied by R

To solve for I you need to isolate it by dividing both sides by R

I = V/ R

Answer: divide both sides by R

Answer:

To make I a subject of the formula V = IR, we divide both sides by R.

Step-by-step explanation:

V = IR

V/R =IR/R

The R in IR/R cancels out because it is on the other side.

We then have:

V/R = I

Which can be written as:

I = V/R

Mapping diagram: Is it a function? (yes /
no
) Why or why not?

Answers

It is a function

Why? Because each input maps to exactly one output. The input oval represents the domain (set of all possible inputs). The output oval is the range, which is the set of all possible outputs. If we had something like the input 0 mapping to the outputs 2 and 4 at the same time, then we wouldn't have a function.

549440

A farmer decides to make three identical pens with 88 feet of fence. The pens will be next to each other sharing a fence and will be up against a barn. The barn side needs no fence. What dimensions for the total enclosure (rectangle including all pens) will make the area as large as possible?

Answers

Answer:

The long fence, AC = 44 feet

4 shorter segments at 11feet each = 44 feet

Area = 484 ft^2

Step-by-step explanation:

The three pens will share one fence section parallel to the barn, we'll call it AB.  Each pen will need two side fence segments, from the front fence to the barn.  We'll call those portions AC.  We need four of them:  two for the outer sides and two more to divide up the space equally among the three pens.  The total area would be AB*AC.

We know that AC + 4AB = 88 feet.

or AC = (88feet - 4AB)

Area = AB(88feet - 4AB)

Area = 88AB - 4AB^2

To maximize the area, we can take the first derivative and set it equal to zero:

Area' = 88 - 8AB

0 = 88 - 8AB

AB = 11 feet

AC = (88 - 4AB)

AC = (88 - 44)

AC = 44 feet

The fours segments of fence:  

AC + 4AB = 88 feet

(44) + 4(11 feet) = 88feet

Area = 44' x 11 ft' = 484 ft^2

James is 5 ft. tall and casts a 6.5 ft. shadow. At the same time, a palm tree casts a 26 ft. shadow. How tall is the palm tree?

Answers

Answer:  20 feet

=====================================================

Work Shown:

(height)/(shadow length) = (height)/(shadow length)

(5 ft)/(6.5 ft) = (x ft)/(26 ft)

5/(6.5) = x/26

5*26 = 6.5*x

130 = 6.5x

6.5x = 130

x = 130/(6.5)

x = 20

The palm tree is 20 feet tall, which is the same height as a 2 story building (assuming each floor is 10 ft).
