Answer:

D

Step-by-step explanation:

we can find x/y by multiply 3a/b * 3a/b

x/y = 9a^2/b^2

Answer:

3

Step-by-step explanation:

So, the little arow underneath lim that says x>1, this means that the qiuestion is asking:

What is the limit when x gets to 1?

We can use the quadratic they give us to solve this. Now, if you are doing this, you should know how to make a quadratic equation. So instead of making this long and tedious for you, I will use a graphing calculator.

So lets look at the graph below, specificly where x=1

as x reaches 1, what does the y coordinates look to be about? 3.

So we can conclude that the answer is that when x→1, y=3

I hope this helps!

Answer:

C. 6

Step-by-step explanation:

ΔADC and ΔACB are similar because two of their angles are congruent (∠ACD and ∠ABC, and ∠DAC and ∠CAB)

Because the sides are similar, you can create a proportion

[tex]\frac{AC}{AD}=\frac{AB}{AC}[/tex]

substitute the given values for the sides. AD=4 and AB=4+5=9

[tex]\frac{AC}{4}=\frac{9}{AC}[/tex]

cross multiply

[tex]AC^{2} =36[/tex]

take the square root of both sides

AC=6

Answer:

2280 the volume

Step-by-step explanation:

So one box = 480

So then what about 6 boxes?

you do 480 x 6 =   2880

480+ 480+ 480+ 480+480+480= 2880

Answer:

$415.63

Step-by-step explanation:

it would have been 393.75, but he worked 5 hours overtime and got paid time and a half for it, meaning his normal pay plus half of it. (only for overtime tho).

so first calculate his normal pay:

40 × 8.75 = 350

then add overtime to it

8.75 × 5 = 43.75

43.75 × 1.5 = 65.625

65.625 + 350 = 415.625

round that and its 415.63!

Answer:

Total surface area = 434 cm²

Total volume = 470 cm³

Step-by-step explanation:

1. The prism can be decomposed into two rectangular prisms which are the bigger rectangular prism and the smaller rectangular prism

✔️Total surface area of the prism = (surface area of the bigger prism - area of the face joined to the smaller prism) + (surface area of the smaller prism - area of the face joined to the bigger prism)

Surface Area of bigger prism = 2(LW + LH + HW)

L = 10 cm

H = 8 cm

W = 9 - 5 = 4 cm

Area of bigger rectangular prism = 2(10*4 + 10*8 + 8*4)

= 304 cm²

Surface area of the smaller prism = 2(LW + LH + HW)

L = 10 cm

H = 3 cm

W = 5 cm

Area of bigger rectangular prism = 2(10*5 + 10*3 + 3*5)

= 190 cm²

Area of the face joining both rectangular prisms = L*W

L = 10 cm

W = 3 cm

Area = 10*3 = 30 cm²

✅total surface area of the prism = (304 - 30) + (190 - 30) = 274 + 160 = 434 cm²

2. Volume of the prism = volume of the bigger rectangular prism + volume of the smaller rectangular prism

✔️Volume of the bigger rectangular prism = L*W*H

L = 10 cm

H = 8 cm

W = 9 - 5 = 4 cm

Volume = 10*8*4 = 320 cm³

✔️✔️Volume of the bigger rectangular prism = L*W*H

L = 10 cm

H = 3 cm

W = 5 cm

Volume = 10*3*5 = 150 cm³

✅Total Volume of the prism = 320 + 150 = 470 cm³

Answer:

Boris=504 keisha=120

Step-by-step explanation:

First you would start off by Multiplying 4x126 the result of that is= 504 so thats how much Boris sent. To get the answer to how many jose sent you simply just subtract 6-126 and that should result in 120

Answer:

what kind of air

Step-by-step explanation:

Answer:

area of rectangle = 110 cm^2

Step-by-step explanation:

here's your solution

=> length of rectangle = 35 cm. [ given ]

=> width of rectangle = 20 cm. [ given ]

=> we need to find area ,

=> area of rectangle = 2(length + width)

=> area of rectangle = 2(35 + 20)

=> area of rectangle = 2*55 =

=> area of rectangle = 110 cm^2

Step-by-step explanation:

We use tangent because it uses opposite over adjacent.

So,

tan 33 = x/46

or

46 * tan 33 = x

Type this into the calculator and you get around 29.87

Answer:

  15

Step-by-step explanation:

Your calculator can tell you √230 ≈ 15.17. The closest integer is 15.

__

If you have memorized the squares of small integers, you know that 15² = 225 and 16² = 256. 230 is closer to 225 than to 256, so √230 will be closer to 15.

Answer:

  no

Step-by-step explanation:

Put 2 where x is and see if you get a true statement.

  1/2(2) -4 = 5

  1 -4 = 5

  -3 = 5 . . . . . . False

2 is not a solution to the equation.
