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:

85

Step-by-step explanation:

2x + 29 + x - 23 = 180

solve for x = 28

b = 2 * 28 + 29 = 85

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:

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:

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

Step-by-step explanation:

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

Answer:

x=5

Step-by-step explanation:

2x=10

Divide each side by 2

2x/2 = 10/2

x = 5

Answer:

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

Answer:

∠ 1 = 63°

Step-by-step explanation:

∠ 1 and 117° are adjacent angles and sum to 180° , that is

∠ 1 + 117° = 180° ( subtract 117° from both sides )

∠ 1 = 63°

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:

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

% 25 = 1/4

Thus :

144 × 1/4 = 36

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:

Amount of water in bottle = 3/8 liter

Step-by-step explanation:

Given:

Total capacity of bottle = 3/4 liter

Amount of water in bottle = 1/2 of total capacity

Find:

Amount of water in bottle

Computation:

Amount of water in bottle = [Total capacity of bottle[1/2 of total capacity]

Amount of water in bottle = [3/4][1/2]

Amount of water in bottle = 3/ [(4)(2)]

Amount of water in bottle = 3/8 liter

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).
