Answers

Answer 1

Answer:

Same arc intercepted, the angles are equal

t = 10°u = 60°v = 40°

Cyclic quadrilateral has supplementary opposite angles

s + v + 60° + 10° = 180°s + 40° = 110°s = 70°

And s and r intercept same arc, therefore:

r = s = 70°

A story owner wants to prepare 100 lb of a candy mix that she will she for $1.36 per lb. She mixes 20 lb of jelly beans that cost 20 cents per lb with sugar candies. How much does 1 lb of sugar candies cost?

Answers

Answer:

1.65

Step-by-step explanation:

100 pounds of the mixture = 1.36 * 100 = 136 dollars.

She uses 20 pounds of jelly beans that cost

20 * .20   = 4.00

136 - 4 = 132 dollars left for 80 pounds of sugar candies.

80 pounds = 132 pounds of sugar candies.

1 pound =  x

80/1 = 132 / x             Cross multiply

80x = 132

x = 132 / 80

x = 1.65 / per pound

Answer number 1 plsssss

Answers

Answer:

At Z-Mart, after the discount it is 7/8 of the original price of 225,

at ABC Sports the final price is 200,

and at Bike World, after the discount it is 3/4 of the original price of 265

so

we multiply 225 by 7/8 to get 196.88,

which is lower than ABC Sports,

and then we multiply 265 by 3/4 to get 198.75, which is higher than Z-Mart

so Z-Mart or A) is correct.

Hope this helps! :D

Find the area using sine rules.

Answers

Answer:

22.44 mi²

Step-by-step explanation:

Step 1

Find the missing angle:

m∠H = 180° - (47° + 99°) = 34°

Step 2

Find the missing sides by using the law of sines:

sin 34° / 5.9 = sin 47° / HP = sin 99° / HKHP = 5.9 sin 47°/sin 34° = 7.7 miHK = 5.9 sin 99° / sin 34° = 10.4 mi

Step 3

Use Heron's formula for the area:

A = [tex]\sqrt{s(s - a)(s - b)(s - c)}[/tex], where s is semi-perimeter, and a, b, c - sides

Find s:

s = 1/2(5.9 + 7.7 + 10.4) = 12

Find A:

A = [tex]\sqrt{12(12 - 5.9)(12 - 7.7)( 12 - 10.4)}[/tex] = 22.44 mi²

Harpo, Groucho, Chico, Zeppo, Gummo, Karl, and Skid have won three tickets to the opera. They will randomly choose three people from their group to attend the opera. How many outcomes are possible?

Answers

Answer:

35

Step-by-step explanation:

This is a combination problem therefore we need to use the combination formula using factorials, plug in the values for n and r which would be 7 since there are 7 individuals in the group and 3 because we are making outcomes of 3.

C(n,r)=C(7,3)

=7!(3!(7−3)!)

=7!3!×4!

= 35

Finally, we can see that the total number of possible outcomes is 35

2) 2/1

3) -1/2

4) -2/1

Step-by-step explanation:

use two ordered pairs to find slope by using this formula:

difference of y-values over difference of x-values

difference of y-values:  4-3 = 1

difference of x-values:  2-0 = 2

The average test score for 8 students is 5 the scores for 7 of the 8 students are shown what is the score of the 8th student

Answers

Answer:

70

Step-by-step explanation

Find the diagram attached

Average = Sum of scores/sample size

Given the 7 numbers

20, 20, 20, 30, 80, 80, 80

Average = 50

5 = 20+20+20+30+80+80+80+x/8

x is the score of the 8th student

50 = 330+x/8

400 = 330+x

x = 400-330

x = 70

Hence the score of the 8th student is 70
