Answer 1

Answer:

find the area of all the shapes

Base x height / 2 = area of triangle

12x10=120/2=60

there are 4 triangles so 60 x 4 = 240 square inches

length x width = area

10 x 10 = 100

240+100=340

C. is the answer

(2x+10)°+(4x+20)°= 180° ( linear pair)

2x+10+4x+20=180

=6x+30=180                     6x=180-30

6x=150

x= 150/6= 25

x=25

2x+10=50+10=60

4x+20=100+20=120

we can check if we did correct if the angles add up to 180 as they are a linear pair

At 50, Brian sets up an IRA, where he plans to deposit $12,000 at the end of each year until age 75. Find the amount of the annuity if he invests in a stock fund that yields 4% compounded annually.

Answers

Answer: the amount of the annuity is $501000

Step-by-step explanation:

We would apply the future value which is expressed as

FV = C × [{(1 + r)^n - 1}/r]

Where

C represents the yearly payments.

FV represents the amount of money

in your account at the end of 25 years.

r represents the annual rate.

n represents number of years or period.

From the information given,

r = 4% = 4/100 = 0.04

C = $12000

n = 75 - 50 = 25

Therefore,

FV = 12000 × [{(1 + 0.04)^25 - 1}/0.04]

FV = 12000 × [{2.67 - 1}/0.04]

FV = 12000 × 41.75

FV = $501000

Renee can see a 25 square foot quilt in 16 hours. Genera can sew the same size quilt in 12 hours. How long would it take them to see the quilt together?

Answers

28 hours because they are too long from each other

Answer:

Approximately 6.86 hours.

Step-by-step explanation:

Renee sews at a rate of 1.5625 sq ft an hour. Found using square feet divided by hours.

Genera sews at a rate of 2.084 sq ft an hour. Found using square feet divided by hours.

To find how fast they can sew the quilt together, we must add their sewing speeds together: 1.5626 + 2.084 = 3.64583333.

Using this equation we can divide a 25 sq ft quilt by their speed of 3.64583333 to get approximately 6.86 hours.

The answer is approximate because we used rounded decimals.

Jillian calculates that see will take 95 minutes to run 7 miles. She runs the distance in 80 minutes. What is Jillian’s percent error? ​

Answers

Answer:

Kawaii, the problem is the comparison with the calculated time for Jillian and the actual time for Jillian to run the 7 miles.

 

%error=(calculated value - experiemental value)/calculated * 100%

 

%error=(95-80)/95*100%=15/95 *100% = 15.79 ≈ 16% error  

 

Note: 16% error is the approximate error because the numbers have 2 significant figures stated in the problem.

8x+c= k

Subtract c from each side

8x+c-c= k-c

8x = k-c

Divide each side by 8

8x/8 = (k-c)/8

x =  (k-c)/8

Which geometry includes a triangle that has angle measures of 45°, 61°, and 70°? Euclidean geometry hyperbolic geometry elliptical geometry spherical geometry

Answers

Answer: Hyperbolic geometry

Step-by-step explanation:

Hyperbolic triangle is a non - Euclidean triangle in which the sum of the angles of the triangle is not up to 180 degrees. That is, less than 180 degree.

Euclidean geometry is the normal geometry that is being taught in school in which the sum of the angles of its triangle equals 180 degrees

While spherical geometry is a non euclidean geometry with sum of the angles of its triangle greater than 180 degrees.

Therefore, the triangle that has angle measures of 45°, 61°, and 70° is a non - Euclidean geometry which is hyperbolic geometry.
