how many times does 90 go into 490

Answer:

Step-by-step explanation:

First off, if side BC and side EC are congruent, then this is an isosceles triangle. It then goes to follow by the Isosceles Triangle Theorem that angle EBC is also 67 degrees. By the Triangle Angle-Sum Theorem then, angle BCE is 180 - 67 - 67 which is 46 degrees. Angle BCE is supplementary to angle FCA which means they add up to equal 180, so angle FCA is 180 - 46 = 134.

Angle FCA = 134

Answer:

13 / 19

Step-by-step explanation:

Given that :

U = 130

Let :

s = swimming pool

t = track

g = gym

n(g) = 61 ; n(s) = 68 ; n(t) = 60

n(g n s) = 25 ; n(t n s) = 30 ; n(g n t) = 19

n(g n s n t) = 6

n(g n t) only = n(g n t) - n(g n s n t) = 19 - 6 = 13

Hence, probability that a randomly scted person uses the gym and track and does not use the swimming pool = n(g n t) only ÷ n(g n t)

= 13 / 19

= 13 / 19

Answer: $20

Step-by-step explanation:

From the question, we are informed that John Smith has a past due balance of $80 on his account and out of the $80 paid, 25% will be given as commission.

Therefore, the total commission received from John's payment will be:

= 25% × $80

= 25/100 × $80

= 0.25 × $80

= $20

The commission is $20

9514 1404 393

Answer:

  1 solution

Step-by-step explanation:

The ratios of x- and y-coefficients are different, so the lines have different slopes. Lines with different slopes intersect at exactly one point. That point is the solution to the system of equations.

There is exactly one solution.

Step-by-step explanation:

We don't know Steve's age, so make his age=x. If his parrot is 19 years old and he's 7 years older than Steve, you would be adding 7 years onto Steve's age. So, to do that it would be x+7=19 or B!

Final Answer: [tex]A[/tex] = [tex]76.76[/tex] [tex]in^2[/tex]

Steps/Reasons/Explanation:

We will be trying to find the area of the rectangle. The formula tells us to multiply width times length. This means that we will multiply our length of 15.2 inches by a width of 5.05 inches to find the area of a rectangle.

The final answer would include [tex]in^2[/tex] because we are multiplying both inches of the length and width to find the area.

Question: What is the area of a rectangle with the length of 15.2 inches and a width of 5.05 in?

Rectangle Area Formula: [tex]Area[/tex] = [tex]width[/tex] × [tex]length[/tex]

[tex]A[/tex] = [tex]15.2[/tex] inches × [tex]5.05[/tex] inches

[tex]A[/tex] = [tex]76.76[/tex] [tex]in^2[/tex]

Answer:

there is alot of them

Step-by-step explanation:

Answer:

m∠3 =  102°

m∠4 =  102°

m∠5 =  78°

m∠6 =  133°

m∠7 =  47°

m∠8 =  47°

m∠9 =  133°

m∠10 =  102°

Step-by-step explanation:

Lines a and b are parallel and

m∠1 = 78° and

m∠2 = 47°

m∠3 = 180 - m∠1 = 180 - 78 = 102°

m∠4 = m∠3 = 102°

m∠5 = m∠1 = 78°

m∠6 = 180 - m∠7 = 180 - m∠2 = 133°

m∠7 = m∠2 = 47°

m∠8 = m∠2 = 47°

m∠9 = 180 - m∠8 = 180 - 47 = 133°

m∠10 = 180 - m∠1 = 102°

Answer:  The Length of the rectangle is 18 feet.

The width is 8 feet

Step-by-step explanation:  Perimeter is 2w + 2L

Length here is 2w + 2   Substitute this value for L in the equation.

P = 2w + 2L

52 = 2w + 2(2w + 2)  distribute and add

52 = 2w + 4w + 4

52 = 6w + 4    Subtract 4 from both sides, Then divide both sides by 6 to solve  for w

48 = 6w

8 = w  The width is 8 ft

Substitute into the original expression for Length

Length here is 2w + 2 :  2(8) + 2   16 + 2 = 18

The Length is 18 feet.

Check:   in the original equation P = 2w + 2L

52 = 2(8) + 2(18)

52 = 16 + 36  TRUE!

Answer:

The length would be 18ft the width would be 8ft

Answer:

D, or the last graph.

Step-by-step explanation:

I got it right when I was doing the assignment :)

From the information given regarding the graph, it should be noted that correct option about the graph of the system is D. On a coordinate plane, 2 dashed lines are shown.

It should be noted that a graph is a mathematical diagram which shows the relationship between two or more sets of numbers.

In this case, on a coordinate plane, 2 dashed lines are shown. The first straight line has a positive slope and goes through (0, 1) and (2, 2). Everything below the line is shaded. The second straight line has a negative slope and goes through (negative 3, 0) and (0, negative 1). Everything above the line is shaded.

Answer: x ≥ 17

Step-by-step explanation:

We know that she worked 7 hours at a dinner, for $10 per hour last week.

Then in the last week, she did make:

7*$10 = $70

Now she babysits, she wins $8 per hour, then if she works x hours, she will win:

w(x) = $8*x

if we add the $70 that she already had, we have:

$70 + $8*x

And we know that she wants to have, at least, $206, then we can write the inequality.

$70 + $8*x ≥ $206.

Now let's solve this for x.

first, we can subtract $70 in both sides:

($70 + $8*x) - $70 ≥ $206 - $70

$8*x ≥ $136

now we can divide by $8 in both sides:

($8*x)/$8 ≥ $136/$8

x ≥ 17

This means that she must babysit for at least 17 hours if she wants to buy the dress.
