Answer: Required inequality: [tex]25+x\leq 50[/tex]

we can add at most 25 pounds.

Step-by-step explanation:

Let x = Weight added.

As per given,

25 pounds + Weight added Must be less than or equal to 50 pounds

i.e. Required inequality: [tex]25+x\leq 50[/tex]

To solve , we subtract 25 from both the sides ,we get

[tex]x\leq 25[/tex]

hence, we can add at most 25 pounds.

Answer:

5^2 = 100

100 x 3.14 = 314

Now we multiply by 20 since it's the height.

314 x 20 = 6,280 cm^3 is your answer.

Formula of cylinder:

H x πr^2

Height x pi(3.14 or 22/7 depending what they tell you to use for pi) x radius being squared (your radius is half of your diameter or given radius).

Answer:

x = 3

AB = 16

Step-by-step explanation:

Given: AM = 8, AB = 5x +1 and M is the midpoint of AB, the AM = MB

AB = 2AM

5x+1 = 2(8)

5x + 1 = 16

x = 16 - 1

5x = 15

x = 15/5

x = 3

Hence the value of x is 3

Since AB = 5x+1

AB = 5(3) + 1

AB = 15 + 1

AB = 16

Answer:

3 1/6

Step-by-step explanation:

19 divided by 6 = 3 1/6

Answer:

3 1/6

Step-by-step explanation:

Answer: Yes

Step-by-step explanation:

You can tell that two of the numbers are only 2 apart, hence CB and CA, and the other one, AB, or the bottom side, is way less.

Answer:

YES IT IS

Step-by-step explanation:

For a triangle to be a right triangle, it must follow pythagorean theorem to find the hypotenuse (long side of triangle).

A squared + B squared = C squared

6 squared + 8 squared = 100

Since we squared our addends, we must find the square root of 100 (which is 10)

Since 10 is one of the side lengths for the hypotenuse since it is the longest, and we got 10 from pythagorean theorem, we know it is a right triangle.

Hope this helps you. Have a great rest of your day.

Answer:

85

Step-by-step explanation:

2x + 29 + x - 23 = 180

solve for x = 28

b = 2 * 28 + 29 = 85

Answer:

25.5

Step-by-step explanation:

Using SOH CAH TOA, you can see that x is the hypotenuse, and 24 is adjacent to the angle 20, so you will need to use CAH.

CAH is cos=adjacent/hypotenuse. Substituting our values in means cos(20) will be equal to 24/x. By cross multiplying, you receive cos(20) x =24. To find x, divide 24 by cos(20) to get 25.5 to the nearest tenth.

Answer:

m=1 (0,3)

Step-by-step explanation:

m=1

slope is 1 because from left to right the line goes up and you move one 1and one to the left so m=1/1 =1

y-intercept is at (0,3) because is where the line intersects the y-axis

I also think- Because you're drawing on the same marble without replacing it.

Answer:

110?

Step-by-step explanation:

From what I read,

500/50= 10

so:

10×11= 110

Answer:

4.5 and 16.5

Step-by-step explanation:

4 + 16 = 20

5 + 17 = 22

(NUMBERS HAVE TO BE BETWEEN 4 - 5 AND 16 - 17)

4.5 + 16.5 = 21

16.5 - 12 = 4.5

Answer:

digit in the unit's place originally = 5

Step-by-step explanation:

x + y = 14

xy - yx = 36

Now, the only single digits that sum up to 14 are;

9 + 5 = 14

8 + 6 = 14

We can't use 7 + 7 because they said there is a difference when the numbers are reversed.

Now, let's assume 95 is the original number since we are told when it is reversed it is lesser.

Thus, when reversed we have 59.

Difference = 95 - 59 = 36

Thus,unit number of original number = 5

Answer:

$0.95

Step-by-step explanation:

total cost of 7 pens = total amount spent - cost of binder

$7.90 - $1.25 = $6.65

cost of each pen = total cost of 7 pens / 7

$6.65 / 7 = $0.95

Answer:

slope = -3 and equation of line is y = -3x+16

rise/run: y2-y1/x2-x1 = 10-16/2-0 = -6/2 = -3

Answer:

0.47 (Yes - This is a terminating decimal)

0.16666... (Yes - This is a repeating decimal)

0.5473... (No - This is a decimal that neither terminates nor repeates)

0.462 (Yes - This is a terminating decimal)

Step-by-step explanation:

A terminating decimal and a repeating decimal are both types of decimals that can be written as fractions. However, if the decimal is neither of these types, it cannot be written as a fraction.

Answer:

14.55'

Step-by-step explanation:

Cosine rule

c^2 = a^2 + b^2 - 2ab cos(C)

here

a=11

b=23

C = 150°

Substitute in cosine rule,

c^2 = 11^2 + 23^2 - 2(11)(23) cos (150°)

= 121 + 529 -2 (11) (23) sqrt(3)/2

=211.791

c = sqrt(211.791)

= 14.55

Answer:

5(2y - 3)

18(1 - y)

1.6 quatrz of corn syrup

Step-by-step explanation:

Using distributive property :

10y - 15

5(2y - 3)

6(3 - 3y)

6*3 - 6*3y

18 - 18y

18(1 - y)

C.)

20% of corn syrup

Amount of food to make = 8 quartz

20% of 8 quartz

20% of 8

0.20 * 8

= 1.6 quartz of corn syrup

Answer:

p = 4

Step-by-step explanation:

Given the expression x ^ 2-px + 3 = 0

If x = 0 is a solution

Substitute into the expression

0² - 0p + 3 = 0

-0p = -3

p = 3/0

p cannot be determined for this root

If x = 1

1² - 1p + 3 =0

1 - p + 3 = 0

-p+4 = 0

-p = -4

p = 4

Hence the va;ue of p is 4

Answer:

B. 12cm

Step-by-step explanation:

We can double check by plugging in the number. However, the question trys to trick you, by giving you the diametre, but in order for the formula to work (V=4 /3πr^3), we will divide the diametre by 2 (12 ÷ 2= 6),

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

Once we do that, we can double check, when you plug in your numbers your answer will be around 900 (904.78, to be exact, but the question asks for approximate diamtetre).

Have a good day :)
