Answer:

10. X = 2.75

11. X = 1.61

Hey there, I have the steps listed below but what is the problem asking, I cannot solve it unless it explains the problem. Thank you!

Step-by-step explanation:

10. 5x + 10 + 11x + 2 = 56

16x + 12 = 56

16/16x = 44/16

X = 2.75

11. -1 + 8x + 18x + 5 = 46

26x + 4 = 46

26/26x = 42/26

X = 1.61

~I hope I helped you! :)~

Problem 10

<h3>Answers:</h3>
  • x = 11
  • angle UTS = 65
  • angle AUT = 123

-----------------------

Explanation:

The remote interior angles UTS and TSU add to the exterior angle AUT. This is because of the remote interior angle theorem. The interior angles you add cannot be adjacent to the exterior angle.

(angle UTS) + (angle TSU) = angle AUT

(5x+10) + (58) = 11x+2

5x+10+58 = 11x+2

5x+68 = 11x+2

68-2 = 11x-5x

66 = 6x

6x = 66

x = 66/6

x = 11

Use this x value to find that...

angle UTS = 5x+10 = 5*11+10 = 65

angle AUT = 11x+2 = 11*11+2 = 123

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

Problem 11

<h3>Answers:</h3>
  • x = 4
  • angle CDB = 31
  • angle WBC = 77

-----------------------

Explanation:

We'll use the same theorem as before

(angle BCD) + (angle CDB) = angle WBC

(46) + (-1+8x) = 18x+5

46-1+8x = 18x+5

8x+45 = 18x+5

45-5 = 18x-8

40 = 10x

10x = 40

x = 40/10

x = 4

angle CDB = -1+8x = -1+8*4 = 31

angle WBC = 18x+5 = 18*4+5 = 77

How many cube-shaped boxes with 12-inch edges can fit into a box thatis 4
DochEvi [55]

Answer:

80

Step-by-step explanation:

First recall that:

1 inch=12 feet

The volume of cube-shaped boxes with 12-inch edges is 1 cm³

The volume of a box that is 4

feet tall, 4 feet long, and 5 feet wide is

given by:

Volume = lwh

We substitute l=4ft, w=5ft and h=4ft

To obtain:

Volume = 4 \times 4 \times 5 = 80 {ft}^{3}

Therefore 80 cube-shaped boxes with 12-inch edges can fit into a box that is 4

feet tall, 4 feet long, and 5 feet wide.

The concept being tested is functions.

The graph describe is a vertical parabola that opens downwards.

All vertical parabolas are functions because the pass the vertical line test.

In other words, each time, t, is associated with exactly one car value, y.

The correct answer is the second option.

David invests 10,000 in a sqving account that pays 3.5% simple interest. If David makes no withdrawals or deposits to the accoun
Triss [41]

Answer:

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the amount invested.

P represents the principal or amount invested.

R represents interest rate

T represents the duration of the investment in years.

From the information given,

P = 10000

R = 3.5%

T = 7 years

I = (10000 × 3.5 × 7)/100 = $2450

The amount that will be in the account after 7 years is

10000 + 2450 = $12450
