Use The Net To Find The Total Surface Area Of The Rectangular Prism.

Answers

Answer 1

Answer:

a. 46m²

Step-by-step explanation:

To find surface area, we must calculate each of the rectangular prism's faces and add them.

1 × 5 = 5

1 × 5 = 5

3 × 5 = 15

3 × 5 = 15

1 × 3 = 3

1 × 3 = 3

5 + 5 + 15 + 15 +3 + 3 = 46

a. 46 m²

I need to find the measure of angle A

Answers

Answer:

∠ A = 30°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

90 + x + 67 + x + 37 = 180, that is

2x + 194 = 180 ( subtract 194 from both sides )

2x = - 14 ( divide both sides by 2 )

x = - 7

Then

∠ A = x + 37 = - 7 + 37 = 30°

what is the slope of the function below y=5x+8​

Answers

Answer:

This function is in y=mx+b form, where m is the slope, and b is the y-intercept.

So, for this equation the slope is 5.

suppose 7,500 is invested at 1.5%, compounded continuously. what will the account balance be in 16 years?​

Answers

Answer:

[tex]\boxed {\boxed {\sf \$9,534.37}}[/tex]

Step-by-step explanation:

The formula for continuously compounded is:

[tex]A=Pe^{rt}[/tex]

where P is the principal amount, r is the interest rate as a decimal, and t is the amount of time.

The principal amount is $7,500 and time is 16 years. The interest rate is 1.5%. Convert this to a decimal- divide by 100 or move the decimal places two spots to the left.

1.5/100= 0.015         or           1.5 --> 0.15 --> 0.015

Now we know all the values and can substitute them into the formula.

[tex]P= 7500 \\r= 0.015 \\t= 16[/tex]

[tex]A= 7500(e^{0.015*16})[/tex]

Solve the multiplication in the exponent first.

[tex]A= 7500(e^{24})[/tex]

Solve the exponent.

[tex]A= 7500 (1.27124915)[/tex]

[tex]A=9534.368627[/tex]

Round to the nearest cent (hundredth place). The 8 in the thousandth place tells us to the round the 6 to a 7.

[tex]A=9534.37[/tex]

The account balance will be $9,534.37 after 16 years.

Russom deposits $500 into a compound interest account. The interest rate for the
account is 3.25%. Determine the account balance after 5 years.

Answers

Answer:

$581.25

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.25%/100 = 0.0325 per year,

then, solving our equation

I = 500 × 0.0325 × 5 = 81.25

I = $ 81.25

The simple interest accumulated

on a principal of $ 500.00

at a rate of 3.25% per year

for 5 years is $ 81.25.

0.24 as a percent. i already know that its 24% but can you show me an explanation

Answers

Explanation:

So any decimal number is the same as a percentage but take off ONE zero in front of it

So with 0.24 for example, you take off the zero in front and since there are no zeros for the decimal point to be behind, there is no need for the decimal point now, so the percentage is 24%

1.4 pounds of almonds, 0.8 pound of cashews, and 2.6 pounds of peanuts. How much does Mila spend in all

Answers

Answer:

the total amount spent is $31.68

Step-by-step explanation:

The computation of total amount spent as follows:

= 1.4 pounds × $9.15 + 0.8 pounds × $10.75 + 2.6 pounds × $3.95

= $12.81 + $8.6 + $10.27

= $31.68

hence, the total amount spent is $31.68

We simply apply the pounds with its price

Directions: Solve for x. Round to the nearest tenth. 16" N 37​

Answers

1776 hope this helps!

The value of x is: x = 35.57.

Here, we have,

given that,

from the given diagram, we get,

it is a right angle triangle,

base = x

hypotenuse = 37

and angle = 16°

now, we know that,

cos θ = adjacent / hypotenuse

so, we get,

cos 16° = x/37

The value of cos 16° is equal to the x-coordinate (0.9613).

∴ cos 16° = 0.9613.

=> 0.9613 = x/37

=> x = 35.57

Hence, The value of x is: x = 35.57.

System of Equations:

8s + 7c = 211

4s + 6c = 138

I used the elimination method and multiplied the second equation by -2

-8s - 12c = -276

add the above to the first equation and get

-5c = -65

c = 13

now find s

8s + 7(13) = 211

8s + 91 = 211

8s = 120

s = 15
