Answer:

The unknown number is -2

Step-by-step explanation:

Let n represent the unknown number then...

12=14+n

Subtract 14 from both sides:

12-14=14-14+n

-2=n

n=-2

Step-by-step explanation:

Answer:

a = 1.972

Step-by-step explanation:

a + 3 1/4 = 5 2/9

find a common denominator

a + 3 9/36 = 5 8/36

a = 5 8/36 - 3 9/36

a = 188/36 - 117/36

a = 71/36

a = 1.982

a =12

Answer: P: 6x - 6 + (pi * x/2) A: 3x^2 - 3x - (pi * (x^2)/4)

Step-by-step explanation:

The missing section is a quarter of a circle. It is the same length at 90 degrees difference following an arc. This radius is X, same as the smaller length of the rectangle. The longer length of the rectangle is 2x-3+x, or 3x-3.

Area: Rectangle area is X * (3x-3) or 3x^2 - 3x. Subtract the missing piece. The full area of the circle would be pi * x^2. Divide by 4 for a quarter circle. So the full area would be 3x^2 - 3x - (pi * (x^2)/4).

Perimeter. x + 2x-3 + 3x-3 + the arc. The arc is a quarter of the circle's circumference. pi * 2x over 4. So total perimeter would be 6x-6 + (pi * 2x/4 or pi * x/2).  

Just my best guess tho

Answer:

120 history textbooks

360 physics textbooks

Step-by-step explanation:

Physics textbooks = 3 times the amount of history textbooks

History textbooks = x

Physics textbooks = 3x

480 = x + 3x

= 4x

480/4 = x

x = 120

120 history books sold

480-120 = 360

360 physics textbooks sold

Answer:

  not similar; corresponding sides are not proportional

Step-by-step explanation:

If the triangles were similar, corresponding sides would be proportional. That is, you would have ...

  AX/AB = AY/AC

Here, those ratios are ...

  6/24 ≠ 10/35

so, the corresponding sides are not proportional, and the triangles are not similar.

Answer:

1/6

Step-by-step explanation:

If you roll a 1 then on the second roll (for a fair 6 sided die) the probability that the second roll is a 1 is 1/6 (assuming independence.

Answer:

1/6

Step-by-step explanation:

If the die is fair (and we will assume that all of them are), then each of these outcomes is equally likely. Since there are six possible outcomes ( A standard die has 6 Number { 1,2,3,4,5,6 } ) , the probability of obtaining any side of the die is 1/6. The probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6, and so on.

The equation 60.1 = 7.2x + 2.5 can be used to find the number of oranges in the bag is 8.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

A grocer sells oranges in bags. Each empty bag weighs 2.5 ounces and each orange weighs 7.2 ounces.

Khalil buys a bag of oranges that weighs 60.1 ounces.

Let x be the number of oranges.

Then the equation will be

y = 7.2x + 2.5

For y = 60.1, the value of x is

[tex]\rm 60.1 = 7.2x + 2.5\\[/tex]

On simplifying, we have

x = 8

Thus, the number of oranges in the bag is 8.

Answer:

A:2

B:-5

C:8

D:-147

Step-by-step explanation:

A: For this one, you can cancel out the negatives. Then just divide 14 by 7. Your final answer is 2. Final Answer : 2

B: This one you can forget about the negative for the first bit. Just divide 15 by 3 to get 5. Now the negative is only on one side of the equation so therefore we add the negative back into our answer. Final Answer : -5

C: Just divide 32 by 4 to get 8. No removal or substitution is needed for this one because both numbers are positive. Final Answer : 8

D: Multiply both numbers normally forgetting about the negative at first. 49 * 3 is 147. Now one of our numbers contain a negative so we plug back the negative into our answer. Final Answer : -147

Step-by-step explanation:

m ∠ 1 = 42 °

m ∠ 2 = m ∠ 4 = m ∠ 9 = m ∠ 12 = ( 180° - 62° - 42° ) = 76 °

m ∠ 3 = m ∠ 6 = m ∠ 7 = 62 °

m ∠ 5 = m ∠ 8 = ( 180° - 62° ) = 118 °

m ∠ 10 = m ∠ 11 = ( 180° - 76° ) = 104 °
