Identify an equation that models the situation and find its solution. Kane planned to build a 53-centimeter-tall model of a buil

alex41 [277]

Answer:

The increment in the model is 106cm

Step-by-step explanation:

Given

$Initial\ Height = 53cm$

$Final\ Height = 159cm$

Required

Determine the increment

To do this, we simply subtract the initial height of the building from the final height

$Increment = Final\ Height - Initial\ Height$

$Increment = 159cm - 53cm$

$Increment = 106cm$

<em>Hence, the increment in the model is 106cm</em>

One acute angle of a right triangle is 12 degrees more than twice the other acute angle. Fine the acute angles of the right tria

Svetlanka [38]

Let one acute angle be X and one be Y
X+Y=90 -------Eq.1
2X+12=Y
2X-Y=-12------Eq.2
solving eq 1&2 we get,
3x=78
∴X=26
substituting value X in equation.1
X+Y=90
Y=90-26
∴Y=64
⇒answer:- X=26°
Y=64°

John needs 7 gallon bottles of water to fill 90water balloons how many gallon bottles of water does John need to purchase to fil

Allushta [10]

Answer:

11 bottles

Step-by-step explanation:

make a proportion because if you're using the same rate proportions can show that it's equal

$\frac{7}{90} = \frac{x}{140}$

cross multiply

$7 *140$ $= 980$

divide the answer by 90 to find x

$980/90= 10.8$

round to 11 because you can't have 10.8 bottles

Can you help with #21 please. I will mark Brainliest.

Leokris [45]

Answer:

A, C, E

Step-by-step explanation:

By analyzing the graph, we can see that the roots are $-2$ and $-4$ .

We now want to find all equations of the form $(x-(-2))(x-(-4))=(x+2)(x+4)=0$ .

This immediately gives C as 1 answer.

We can expand our equation to find other possible solutions!

By the FOIL method: $(x+2)(x+4)=(x)(x)+(2)(x)+(4)(x)+(2)(4)=x^2+6x+8=0$

We can then divide both sides of the equation to find that $-x^2-6x-8=0$ , so A is another answer.

We can complete the square on $x^2+6x+8$ to find the last possible solution.

$x^2+6x+8=x^2+6x+9-9+8=x^2+6x+9-1=(x+3)^2-1=0$ .

We can then multiply both sides of the equation by $4$ to find that $4(x+3)^2-4=0$ , so E is the last answer.

The proof that the other answers don't work is left as an exercise.

So, the answers are A, C, and E, and we're done!
