Help! 15 points + brainliest!

The box has volume

11 in × 3 in × x in = 33x in³

and surface area

2 (11 in × 3 in + 11 in × x in + 3 in × x in) = (66 + 28x) in²

The volume and area have the same value if

33x = 66 + 28x

Solve this equation for x :

33x - 28x = 66

5x = 66

x = 66/5 = 13.2

Answer:

104

Step-by-step explanation:

100%= 1.00

so

420%= 4.20

Multiply 4.20×20

84

now add the original 20

104. She has 104 boxes in total.

Answer: slope equals 2/6 =1/3= 0.33333

Step-by-step explanation:

Answer:

The slope of the line with points (-3,0) and (3, 2) is:

Step-by-step explanation:

Given the points

Determining the slope between (-3,0) and (3, 2)

(x₁, y₁) = (-3,0)  

(x₂, y₂) = (3, 2)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [2 - 0] / [3 - (-3)]

               = 2/6

               = 1/3

Thus, the slope of the line with points (-3,0) and (3, 2) is:

Answer:

0.375

Step-by-step explanation:

Answer:

about 214.1

Step-by-step explanation:

Since pi r squared is the formula for a circle's area, you would do the opposite. First, you would divide 144001 by pi which is about 45,836.94. Then, you would find the square root of that which is about 214.1.

Answer:

1 ≤ x ≤ 5

Step-by-step explanation:

Answer:

the answer will be 15 number D

Answer:

x = 15 (D)

Step-by-step explanation:

First, we distribute the -1/2:

-1/2 x x = -1/2x

-1/2 x 5 = -2.5

Now we have -1/2x + (-2.5) = -10

Move the variables to one side and the regular numbers on the other (in other words, subtracting both sides by -2.5:

-1/2x = -10 + 2.5

-1/2x = -7.5

x = -7.5/(-1/2)

x = 15   (D)

Answer:

5, -5

Step-by-step explanation:

We have the problem x^2+5=30

Same to both sides

x^2=25

And 25 is a perfect square, x = 5

BUUUUUUUT..........

x could also equal to -5 because no numbers that are squared can be negative

Confused?

Squaring a number means doing the number multiplied by itself

A negative multiplied by a negative equals a positive

A positive multiplied by a positive equals a positive

Under no circumstances can something squared be a negative number

-5*-5 also equals 25.

So those are your two numbers

Answer:

£210

Step-by-step explanation:

Given that :

Visa cost = £2300

7% charge of visa price = (0.07 * £2300) = £161

Total cost = £(161 + 2300) = £2461

Amount to be saved per month = £2461 / 12 = £205.08333

= £210 (nearest £10)

Answer:

only -2 is in the domain

Step-by-step explanation:

For negative values under the sqrt, there is no real answer, hence

-2x ≥ 0

only for x=-2 this is the case.

The domain represents all the valid input values for x.

Answer:

point form=7,11     x= 7,y =11

Step-by-step explanation:

Answer:

Step-by-step explanation:

y=2x-3

y=x+4

2x-3=x+4

2x-x=4+3

Step-by-step explanation:

Step-by-step explanation:

Question 15:

5(x - 9) - 2(x + 3)

= (5)(x) + (5)(-9) - (2)(x) - (2)(3)

= 5x - 45 - 2x - 6

= 3x - 51

= 3(x - 17).

Question 16:

The terms 36x, 18y and 9 have GCF of 9.

Hence 36x - 18y + 9 = 9(4x - 2y + 1).

Answer:

Answer:

The number of cheery pieces in the box are [tex]18[/tex].

Step-by-step explanation:

Let the number of orange pieces in the box be [tex]x[/tex].

The box contains three times as many cherry pieces as orange pieces.

So, the number of cherry pieces in the box be [tex]3x[/tex].

It has four more grape pieces than cherry pieces.

So, the number of grape pieces in the box be [tex]3x+4[/tex].

There are [tex]46[/tex] total pieces in the box.

So, [tex]x+3x+3x+4=46[/tex]

[tex]\Rightarrow 7x+4=46[/tex]

[tex]\Rightarrow 7x=46-4[/tex]

[tex]\Rightarrow 7x=42[/tex]

[tex]\Rightarrow x=\frac{42}{7}[/tex]

[tex]\Rightarrow x=6[/tex]

So, the number of cherry pieces [tex]=3x=3\times 6=18[/tex].

Hence, the number of cheery pieces in the box are [tex]18[/tex].

Answer:

72, 48

Each segment would be worth 12 hours. 6*12 is 72, 4*12 is 48. 72+48 is 120.

Answer:

8) x = 3

9) x = 10

Step-by-step explanation:

8) 45° ≅ 15x, therefore, the equation would look like: [tex]45 = 15x[/tex]

☆Let's solve it!

[tex] \frac{45}{15} = \frac{15x}{15} \\ 3 = x[/tex]

9) 12x - 10 is supplementary to 8x - 10. So the equation would be: [tex]12 x- 10 + 8x - 10 = 180[/tex]

☆Let's solve it!

[tex]12x - 10 + 8x - 10 = 180 \\ 20x - 20 = 180 \\ \frac{ \: \: \: \: \: \: \: \: \: \: + 20 = + 20}{ \frac{20x}{20} = \frac{200}{20} } \\ x = 10[/tex]

Answer:

B

Step-by-step explanation:

Lets look at A. In A, It says 0.510 is greater than 0.510. That is not true becuase both are equal. A is false.

Lets look at B. In B, it says 0.501 is less that 0.510. This is true. 501 is less than 510. B is true.

Lets look at C. In C, it says 0.061 is greater than 0.510. This is not true becuase 61 is not greater than 510. C is false.

Lets look at D. In B, it says that 0.500 is greater than 0.510. This is not true becuase 500 is less than 510. D is false.

B is the correct answer. I hope this helps! Let me know if I got something wrong so I can fix it.
