First apply the PEMDAS rule:Parenthesis, Exponents, Multiplication, Division, Adding, Subtracting.

4² + 6 ÷ 2

4 x 4 = 16

16 + 6 ÷ 2

6 ÷ 2 = 3

16 + 3 = 19

4 consecutive odd integers add up to -200. Find the integers.

Let
x = first odd integer
x + 2 = second odd integer
x + 4 = third odd integer
x + 6 = fourth odd integer

x + (x + 2) + (x + 4) + (x + 6) = -200
4x = -200 - 2 - 4 - 6
4x = -212
x = -53

Therefore, the four consecutive integers are -53, -51, -49, -47.

Find the circumference of the circle. Round your answer to the nearest hundredth in the center of the circle is 4.5 ft. a 14.14 b 15.90 c 16.82 d 17.43

Answer:

a. 14.14 ft²

Step-by-step explanation:

The measurement given refers to the diameter of the circle. The formula for the circumference and area uses the radius of a circle, therefore it is always safer to use radius instead of diameter

The radius is half of the diameter, which is 2.25 ft.

A=2*r*\pi \\A=2*2.25*\pi \\A=14.14ft^{2}

Write or draw to explain a way to find each sum: 6+7, 8+4, 2+9

Step-by-step explanation:

For 6+7, on a number line we have placed a point A on value 6. On moving 7 units in the rightwards direction a point B is marked. That means when we move from 0 to point B, we get the result for 6+7 = 13.

For 8+4, on a number line we have placed a point C on value 8. On moving 4 units in the rightwards direction a point D is marked. That means when we move from 0 to point D, we get the result for 8+4 = 12.

For 2+9, on a number line we have placed a point E on value 2. On moving 9 units in the rightwards direction a point F is marked. That means when we move from 0 to point F, we get the result for 2+9 = 11.

QUESTION POSTED AT 14/12/2019 - 06:22 PM

Sam needs 5/6 cup mashed bananas and 3/4 Cup mashed strawberries for a recipe. He wants to find whether he needs more bananas or more strawberries . How can he write 5/6 and 3/4 as a pair of fractions with a common denominator

Answer: He needs more strawberries than banana.

Step-by-step explanation:

Since we have given that

Number of cups of mashed bananas is given by

\frac{5}{6}

Number of cups of mashed strawberries is given by

\frac{3}{4}

We need to find whether he needs more bananas or more strawberries.

For this we need a common denominator.

1) Taking L.C.M.  of denominator :

L.C.M. OF 6  and 4 = 12

2) Make the common denominator i.e. 12 for both the fractions.

\frac{5}{6}\times \frac{2}{2}=\frac{5\times 2}{6\times 2}=\frac{10}{12}\\\\and\\\\\frac{3}{4}\times \frac{3}{3}=\frac{3\times 3}{4\times 3}=\frac{9}{12}

so, we can see that

\frac{10}{12}>\frac{9}{12}

He needs more strawberries than banana.
