Joe is finding the length of a rectangular prism. The volume of the prism is 204 ft3. The width is 3.5 ft, and the height is 5 ft. His work is shown below.

V = l w h. 204 = 3.5 (5) l. 204 = 8.5 l. StartFraction 204 Over 8.5 EndFraction = StartFraction 8.5 Over 8.5 EndFraction l. 24 = l.

What error did Joe make?
He incorrectly substituted into the volume formula.
He added 3.5 and 5 when he should have multiplied them.
He incorrectly divided 204 by 8.5.
He did not make a mistake in finding the length of the prism.

Answer:

x = 36

Step-by-step explanation:

180 - 48 = 132

This is because angle AC- and ACB form a straight angle (180 degrees).

132 + 12 = 144

180 - 144 = 36

The three interior sides of a triangle always add up to 180 degrees.

Factor the expression
x2 + 4xy - 117y2?

Answers

Lets Factorize the given expression:-

[tex]️{x}^{2} + 4xy - 117 {y}^{2} [/tex]

Splitting the middle term :-

[tex]{x}^{2} - 9xy + 13xy - 117 {y}^{2} [/tex]

[tex]( {x}^{2} - 9xy) + (13xy - 117 {y}^{2})[/tex]

[tex]x(x - 9y) + 13y(x - 9y)[/tex]

[tex](x - 9y)(x + 13y)[/tex]

So, the final answer is:-

[tex](x - 9y)(x + 13y)[/tex]

2/3 of a number is less than the original number by 20. Find the number.​

Answers

Question :-

2/3 of a number is less than the original number by 20. Find the number.

Required Solution :-

The original no. is 60

Explanation:-

Let the original no be" x "

It’s given, 2/3 of a number is less than the original number by 20.That means 2/3 of a no is =2/3x And 20 less than the original no = x-20.

[tex]\qquad[/tex] According to the question :-

[tex]\qquad \pmb{\sf\longrightarrow \dfrac{2}{3 }x= x-20}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow \dfrac {2}{3}x-x=-20}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow \dfrac{ 2x-3x}{3}=-20}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow \dfrac{ -1x}{3}=-20}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow -1x=-20\times 3}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow -1x=-60}[/tex]

[tex]\qquad \longrightarrow {\pink{\underline{\underline{\pmb{\sf{ x= 60}}}}}}[/tex]

Therefore

The original no. is 60.

Find the rate of change between:
(1,4)
(5,2)

Answers

Answer:

-1/2

Step-by-step explanation:

In a function, the rate of change from x = a to x = b is

rate of change = [f(b) - f(a)]/(b - a)

Here we have

a = 1, f(a) = 4

b = 5, f(b) = 2

rate of change = (2 - 4)/(5 - 1)

rate of change = -2/4 = -1/2

Find the area of the unshaded region in Fig, where ABCD is a square of side 20 cm and semicircles are drawn with each side of the square as diameter. (Use π = 3.14)​

Answers

Answer:

229

Step-by-step explanation:

Area of square is = 20 * 20 = 400

radius = 20 / 2 = 10

Area of semi circle is = 1/2 * πr²

= 1/2 * 3.14 * 10²

= 1/2 / 314

= 157

assume there are four shaded regions for the figure

Area of 4 semicircles−Area of shaded region=Area of square ABCD

Area of shaded region=Area of 4 semicircles−Area of square ABCD

= 4 * 157 - 400

= 628 - 400

= 228

so each single shaded area is 228/4

= 57

now in your problem there are 3 shaded regions like this

so area of unshaded region is =

Area of square - 3 * shaded region area of one region

=> 400 - 3 * 57

=> 400 - 171

=> 229

Quite an aggressive question but I gotchu

When you’re finding a line perpendicular to a given equation, the slope will be the negative reciprocal: that is, if “m” is representing the current slope and “m’” represents the new slope, then m’ = -1/m. Therefore, the new slope will be -1/(-3) or simply 1/3. As for the point, we must substitute in the values with our current slope. If x0 is the x-intercept (what x equals when y=0), then we have y=(1/3)x + x0. If y=5 and x=8 as it is with the given point, we have 5=(1/3)(8) + x0. Solving this we get x0=(7/3)… then the equation of the first problem is y=(1/3)x + (7/3)

As for the second problem, the slope is the same (-3). Just have y=-3x+x0, and subbing in the point we have 5=-3(8)+x0. For this to be true, x0 must be 29 (found by solving the equation). Therefore the answer to the second problem is y=-3x+29.

I WILL GIVE YOU BRAINLIST Liam and kiki are tigers living at the libertyville zoo. Liam weights 7 pounds for every 4 pounds that Kiki weighs. If Liam is 90 pounds more than Kiki, how many pounds does he weigh?​

Answers

Answer:  Kiwi is 120 lbs and Liam is 210 lbs

Step-by-step explanation:

Let L= Liam's weight, and K = Kiwi's weight.

We know that L/K = 7/4

We also know that L = K + 90

Rearrange the first equation to find K:  

L/K = 7/44L = 7KK = (4/7)L

Now use K = 4L/7 in the second equation:

L = K + 90L = (4/7)L + 90(3/7)L = 90L = (90)*(7)/3L = 630/3L = 210 lbs

Check the math:

If L = 210, then K must be L - 90, or 120 pounds

Does L/K = 7/4?

(L/K) = (210/120) = 7/4  YES
