Two Lines Intersect. Find The Value Of B And C.b42

Answers

Answer 1

Answer:

b=42 degrees

c= 138 degrees

Step-by-step explanation:

B and the 42 degrees shown are congruent angles so therefore both are 42 degrees

To find C: We know that combining the 42 degrees and Angle C would form a flat angle or 180 degree angle, so therefore

subtract 180 with 42 to get Angle C

180-42= 138

Answer 2

Answer:

b=42, c=138

Step-by-step explanation:

B has to equal 42 because b is opposite of the 42º

and since 42+2c+42 has to equal 360, we simplify the expression to get:

84+2c=360,

2c=276

c=138

The binomial whose greatest common factor is 2a³ is 8a⁴ + 10a³.

What is  greatest common factor?

The largest number among all the common factors of the given numbers is known as the GCF (Greatest Common Factor) of two or more numbers. The greatest integer that may be used to divide two natural numbers x and y without producing any remainders is called their GCF. There are three main methods for calculating GCF: division, multiplication, and prime factorization.

Given the a³ is not common in  A and B they are wrong

C. 8a⁴ + 10a³

common factors of 8 and 10 is 2

so 8a⁴ + 10a³  has factors 2a³

Hence option C is correct.

<u is 75

< v is 29

<w is 76

Step-by-step explanation:

< u + < v +< w = 180

<w + 3x+35 = 180

so 3x+35= <v+ <u

3x+35=x+52+x+6

3x+35= 2x+58

x+35=58

x= 23

so each angle

U= (23+52)= 75

V= (23+6)= 29

W=180-75-29= 76

or 3(23)+35+w=180

104+w=180

w= 76

William bought a new storage box to hold all of her fishing supplies. His box measures 13 1/7 inches long, 7 2/5 inches wide, and 4 3/4 inches tall.

Answers

Answer:

461.97 in³

Step-by-step explanation:

Given the following measurement for the dimension of a box : 13 1/7 inches long, 7 2/5 inches wide, and 4 3/4 inches tall.

The volume of a box is calculated using the relation :

Volume = Length * width * height

Volume = 13 1/7 * 7 2/5 * 4 3/4

Volume = 92/7 * 37/5 * 19/4

Volume = (92*37*19) / (7*5*4)

Volume = 64676 / 140

Volume = 461.97 in³

Joseph and Isabelle left Omyra’s house at the same time. Joseph jogged north at 8 kilometers per hour, while Isabelle rode her bike west at 12 kilometers per hour. Omyra tried to figure out how far apart they were after 1.5 hours. Her work is shown below. Which statements describe her errors? Check all that apply.

A right triangle. The distance north from Omyra's House is 8 kilometers, and the distance west is 12 kilometers.

8 squared + 12 squared = d squared. 64 + 24 = d squared. 88 = d squared. StartRoot 88 EndRoot = d. 9.4 almost-equals d.
She did not find the full distance each traveled in 1.5 hours. She should have used 12 km for Joseph’s distance and 18 km for Isabelle’s distance.
She did not square the 12 in the problem. She should have used 12 squared = 144.
She did not evaluate 8 squared correctly. She should have used 8 squared = 8 (2) = 16.
She did not evaluate StartRoot 88 EndRoot correctly. She should have used StartRoot 88 EndRoot almost-equals 44.
She should not have taken the square root of each side when solving. She should have just divided each side by 2.
She should not have added the squares in the first step. She should have used 12 squared minus 8 squared = d squared.

Answers

For this case the distance will be given by:

d ^ 2 = (12 * 1.5) ^ 2 + (8 * 1.5) ^ 2

Rewriting we have:

d ^ 2 = (18) ^ 2 + (12) ^ 2

d ^ 2 = 324 + 144

d ^ 2 = 468

d = root (468)

d = 21.63 Km

Answer:

1) She did not find the full distance each traveled in 1.5 hours.

2) She should have used 12 km for Joseph's distance and 18 km for Isabelle's distance.

Anson's toy rocket is shown. What is the volume of the rocket? Round to the nearest tenth if necessary.

Answers

Answer:

The answer is below

Step-by-step explanation:

The rocket is made up of square pyramid and a rectangular prism. Hence the volume of the rocket is the sum of the volume of the square pyramid and the volume of the rectangular prism.

Volume of square pyramid = a²h/3

a = base length = 1.1 in, h = height of pyramid = 2.1 in

Volume of square pyramid = a²h/3 = 1.1² * 2.1/3 = 0.847 in³

Volume of rectangular prism = length * breadth * height = 1.1 * 1.1 * 8.2 = 9.922 in³

Volume of rocket = volume of prism + volume of pyramid = 0.847 + 9.922 = 10.769 in³

Find the surface area
please show work

Answers

363 inch²

Step-by-step explanation:

Each vertical face is a rectangle.

Area of each face = length x breadth

= 8 x 6 inch² = 48 inch²

There are 5 such faces, total area = 5 tiimes of 48 inch² = 240 inch²

For horizontal faces:

Observe: you can actually divide that face in 5 right-angled triangle(two edge point & centre form right angled ∆). With base 6 inch & height 4.1 inch.

For 2 such faces, you have 2 x 5 times of area of 1 ∆.

Area of 10∆s = 10 ( ½ x 4.1 x 6) = 123 inch²

Total area = area of horizontal surfaces + area of vertical surfaces

Total area = 240 + 123 inch² = 363 inch²

We can say that 79=3t-8. Next, we can subtract 8 on each side to get 71=3t. Then, we can divide by 3 to get that Tom has 23 2/3 points.

Answer:

FV= 200*(1.07^n)

Step-by-step explanation:

Current population= 200 deer

Growth rate= 7% per year

To calculate the future value of deer in any given years, we need to use the following formula:

FV= PV*(1+g)^n

FV= future value

PV= present value

g= growth rate

n= number of years

FV= 200*(1.07^n)

For example, the population in 5 years:

FV= 200*(1.07^5)

FV= 281
