Find the area of the figure above.

Answers

Answer:

84

Step-by-step explanation:

You do problems like these by finding the area of each shape individually and then adding them together. I first found the area of the rectangle by multiplying 6 in. by 11 in. to get 66 in.^2. I then found the area of the triangle by multiplying length of the base of the triangle which is the same as the short side of the rectangle at 6 in. by the 6 in. height and dividing it by 1/2. This gets 18 and 66+18=84

Answer:

2/5

Step-by-step explanation:

In order to find the probabability, you first need to find your total. So:

A, B, C, D,

8+ 6 + 4 + 2 =

20

Since, 20 is out toal it goes in our denominator

Now since we artrying to find the probability of A then we count the number of students who an A and place that in our denominator

8/20

We simplify

According to the synthetic division below, which of the following statements
are true?
Check all that apply.

Answers

The correct statements about given synthetic division are C, D, and F

What is a quadratic polynomial?

"It is a polynomial with degree 2."

What is synthetic division?

"It is defined as a way of dividing one polynomial by another polynomial of first degree."

For given question,

We have been given a quadratic polynomial [tex]F(x)=4x^{2} -17x-15[/tex]

We can factorize above quadratic polynomial as,

[tex]F(x)\\=4x^{2} -17x-15\\=4x^{2} -20x+3x-15\\=4x(x-5)+3(x-5)\\=(x-5)(4x+3)[/tex]

This means the factors of [tex]4x^{2} -17x-15[/tex] are (x - 5) (4x + 3)

And the roots of the polynomial would be,

[tex]\Rightarrow F(x)=0\\\Rightarrow 4x^{2} -17x-15=0\\\Rightarrow (x-5)(4x+3)=0\\\Rightarrow x-5=0~~,~~4x+3=0\\\Rightarrow x=5~~,~~x=-\frac{3}{4}[/tex]

This means, the roots of [tex]4x^{2} -17x-15[/tex] are 5 and [tex]\frac{-3}{4}[/tex]

Therefore, the correct statements about given synthetic division are C, D, and F

The school play is selling tickets for their annual fall play. Adult tickets cost $7 each and
children’s tickets cost $4 each. The theatre holds 100 seats and the play is sold out! If $592 were made off of ticket sales, how many of each kind of ticket were sold

Answers

Answer:

64 adult tickets were sold and 36 children tickets were sold

Step-by-step explanation:

i created two equations. 7A + 4C = 592 and A + C = 100. A stands for adult tickets and C stands for children tickets. in order to find the value of C, the children tickets, i took the second equation, A + C = 100, and subtracted A on both sides to get C = -A + 100. i then plugged the value of c into the first equation i created. i then got 7A + 4(-A+100) = 592. after that, i distributed the 4 into the parentheses and got 7A - 4A + 400 = 592. from there, you solve and get 3A = 192. divide 3 from both sides, and get the value of A = 64. then, you go back to the second equation, A + C = 100, and plug in your value of A to get 64 + C = 100. you can then go on to solve for C and get 36. your final answer is 64 adult tickets and 36 children tickets were sold.

So first you need to find all the angles.

Triangles all have a total degree of 180.

Then you can start doing trig. To find c I did (4sqrt3)cos60 that equals 3.464 which is 2sqrt3. Then I figured out a by doing the same thing but with sine. (4sqrt3)sin60 and that equals 6. Then I moved to the other triangle. I figured out d next. 6tan45° and that equals 6. Then I did b by doing 6/cos45 and I got 6sqrt2

What is the solution to the following system of equations?

2x + y = 0

x + 2y = 3

Group of answer choices

(0, 0)

(-1, 2)

(2, -4)

(-5, 4)

Answers

Answer: (-1,2)


Steps:

Solve by elimination

Multiply the first equation by 2 to make the coefficients of x in both equations the same

2(x+2y=3)

2x+4y=6

Then line them up and subtract

2x+y=0
-2x+4y=6

= -3y=-6

Divide both sides by -3 to isolate y

y=2


Then substitute 2 for y into one of the equations to find x.

x+2(2)=3

x+4=3

x=-1

Solve for x: 10(x + 1) = 2x - 7

Answers

Answer:Simplifying

x = -2.125

Step-by-step explanation:Add '-10' to each side of the equation.

10 + -10 + 8x = -7 + -10

Combine like terms: 10 + -10 = 0

0 + 8x = -7 + -10

8x = -7 + -10

Combine like terms: -7 + -10 = -17

8x = -17

Divide each side by '8'.

x = -2.125

Simplifying

x = -2.125

Answer: x=-17/8


First, distribute the 10

10x + 10 = 2x - 7

Next, move the x-values to one side

8x = -17

Now, isolate the x by dividing both sides by 8

x = -17/8

Callum and Isobel have a total of 240 stamps.

Callum buys some stamps from Isabel.
The ratio of the number of Caullum’s stamps to the number of Isabel’s stamps is now 3:2
How many stamps does Callum buy from Isabel?
You must show all your working.
Please help.

Answers

Answer:

Total stamps = 240

ratio= 3:8

3x + 8x = 240

11x = 240

x = 240/11 = 21.8

then, callum's stamps = 3x = 3 * 21.8 = 65.4

Isabel's stamps = 8x = 8 * 21.8 = 174.4

After buying the stamps,

ratio = 3:2

callum's stamps = 3x

Isabel's stamps = 2x

= 3x + 2x = 240

5 x = 240

x = 240/5 = 48

callum's stamps = 3x = 3 * 48 = 144

Isabel's stamps = 2x = 2 * 48 = 96

no. if stamps bought by calling = 144 - 65.4 = 78.6 stamps
