Answer:

For a rectangular prism use this formula to find the surface area:

SA of rectangular prism = 2(lw + wh + lh), where, l is length, w is width and h is the height of the prism.

Now, let's input our numbers given into the equation.

SA = 2(7×6 + 6×2 + 7×2)

Okay, so now that we have an equation filled out, let's solve to find the Surface Area of this rectangular prism.

SA = 2(7×6 + 6×2 + 7×2)

SA = 136 square yards

Step-by-step explanation:

Jen invested $3500 into a continuously compounded account with an interest rate of 3.1%. After 9 years, how much money is in the

GarryVolchara [31]

Answer:

≈$4607

Step-by-step explanation:

I will assume it's compounded yearly.

Apply the compound interest formula.

$A=P(1+\frac{r}{n})^{nt}$

A = Total

P = Initial Principle

r = Interest Rate

n = number of interest in every t period

t = number of periods

In the case,

P = 3500

r = 3.1% = 0.031

n = 1

t = 9

Hence,

$A=3500(1+\frac{0.031}{1})^{1*9}$

$A = 4606.764717......$

A ≈ 4607 (nearest whole number)

What is the ordered pair for point b on the graph (-1,4) (4,-1) (5,1) (1,5)

IRINA_888 [86]

Option C: (5,1) is the ordered pair for point B

Explanation:

The graph is plotted with unit scale 1 units for both x and y axis.

We need to determine the ordered pair for point B.

<u>Ordered pair:</u>

Since, the graph is plotted with unit scale 1, the point B is 5 units away from the point (0,0)

Thus, the x - coordinate for point B is 5.

Also, the point B is 1 unit away from the point (0,0)

Thus, the y - coordinate is 1

The coordinates of point B is (5,1)

Thus, the ordered pair for point B is (5,1)

Hence, Option C is the correct answer.

The Better Nutter Butter Co packed 400 lb. of peanut butter into jars holding 2.5 lbs. each. How many jars were used?

Rus_ich [418]

Answer:

160 jars

Step-by-step explanation:

To find how many jars were used, we just need to divide the amount of stuff by the amount of stuff a jar can hold.

400 (the amount of peanut number in pounds) / 2.5 (the amount of peanut butter each jar can hold) = 160.

So, 160 jars were used to package the 400 pounds of peanut butter.

Can you help me please

user100 [1]

The answer to this question is 10. The working out is shown in the image attached.

*** Sorry instead of writing 170 I wrote 270 for the big angle.. other than that it's correct

or another way to solve this is....

we know that a straight line is 180 degrees and the angle APD is 170 all we need to do is subtract 170 from 180 to get the answer of DPB

Hope this helped
