Answer: (I trust you can graph the points)

{(6,9), (7, 7), (8, 5), (9, 3), (10, 1)}

Step-by-step explanation:

-2x+21

x=6 -12+21 = 9

x=7 -14+21 =7

x=8 -16+21 = 5

x=9 -18+21=3

x=10 -20+21=1

Solve for x. hint:half circle.

Romashka [77]

Answer:

$x = 10$

Step-by-step explanation:

Given

The attached circle

Required

Find the measure of x

From the attached image:

$11x + 2$ and $-2 + 7x$ form a semi-circle

So:

$11x + 2 -2 + 7x = 180$

Collect like terms

$11x + 7x = 180+ 2 -2$

$18x = 180$

Solve for x

$x = \frac{180}{18}$

$x = 10$

Law of sines: Sinca) = sin(B) = sin(C)

ioda

Answer:

no trangles can be formed

Step-by-step explanation:

We have been given angle A as 75 degrees and sides a = 2 and b = 3.

Using Sine rule, we can set up:

sin(a) sin(b)

------------ = ------------

A B

Upon substituting the given values of angle A, and sides a and b, we get:

sin(75) sin(B)

------------ = ------------

2 3

Upon solving this equation for B, we get:

----->3sin(75)=2sin(B)

----->sin(B)=3sin(75)

-------------

------>sinB=1.4488

Since we know that value of Sine cannot be more than 1. Hence there are no values possible for B.

Hence, the triangle is not possible. Therefore, first choice is correct.

In The autumn 40% of the leaves on a tree are yellow and 24% of them are green the remaining 72 leaves are half yellow how many

Charra [1.4K]

Percentage of yellow leaves on a tree during Autumn = 40%

Percentage of green leaves on a tree during Autumn = 24%

Percentage of half yellow leaves on the tree during Autumn :

$= \tt100 - 40 + 24$

$= \tt 100 - 64$

$= \tt 36 \%$ Thus, the percentage of half yellow leaves on the tree during Autumn = 36%

Number of half yellow leaves on the tree = 36%

Let the total number of leaves on the tree be x.

Which means :

$= \tt36 \% \: of \: x = 72$

$= \tt \frac{36}{100} \times x = 72$

$= \tt \frac{36 \times x}{100} = 72$

$= \tt \frac{36x}{100} = 72$

$= \tt 36x = 72 \times 100$

$= \tt36x = 7200$

$= \tt x = \frac{7200}{36}$

$\color{plum} = \tt \: x = 200$

Thus, total number of leaves on the tree = 200

Number of yellow leaves on the tree :

$= \tt40 \% \: \: of \: \: 200$

$= \tt \frac{40}{100} \times 200$

$= \tt \frac{40 \times 200}{100}$

$= \tt \frac{8000}{100}$

$\color{plum} \tt = 80 \: yellow \: \: leaves$

Thus, total number of yellow leaves on the tree = 80

Number of green trees on the tree :

$= \tt24 \% \: \: of \: \: 200$

$= \tt \frac{24}{100} \times 200$

$= \tt \frac{24 \times 200}{100}$

$= \tt \frac{4800}{100}$

$\color{plum} = \tt 48 \: green \: \: leaves$

Thus, the total number of green leaves on the tree = 48

Since the sum of all types of leaves form 200[80+48+72=200], we can conclude that we have found out the correct number of each type of leaf.

▪︎Therefore, <em>the total number of leaves on the tree = 200</em>

A student bought 5 coats at $86 each and paid for them with only $20 bills. How many bills did it take ?

aleksandr82 [10.1K]

It took 22 $20 bills . $86 x5= $430
Then $430 divide by 20 = 21.5
So you can’t have half a bill do the answer has to be rounded up to 22 twenty dollar bills
