Step-by-step explanation:

answer is c=26

hope that helped loll

Answer:

by using angle sum property

Angles a+b+c = 180 degree.

thus, 42+86+c= 180

128+c=180

c=180-128

c=52

principal amount by women for savings = $ 580

duration = 1 year and rate of interest on it = 6 .1/2 % = 13/200

now amount of interest she'll be earning = $580 x 1 x 13 /200 = $37.7

thats  37 dollar 70 cents

14x+70+20x+8 =180

34x + 78 = 180

34x = 102

X = 3

ABX 14(3)+70 = 112

CBX = 20(3) +8= 68

Answer:

70% of the people at the fair are students

165 people are on the ride

Step-by-step explanation:

In order to find a percentage, take the fraction given, 385/550, and divide the numerator, 385, and divide it by the denominator, 550. Once completing this, we get 0.7

Next, we multiply the result by 100, and get 70, thus, 385 is 70% of 550.

To find how many people 30% of 550 is, we take the percentage and put it in a fraction with the denominator being 100(changes with size of fraction like a decimal, 300 would be over a denominator of 1000)

With 30/100, we then multiply by 550 with the equation looking like this:

30/100*550/1

Once we finish multiplying(typically using a calculator, although you can do it manually) we get 165, the value of how many people are on rides out of the total 550.

Answer:

-2

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

Answer:

22) 3 in<x<11 in

23) 8 cm<x<26 cm

24) 0 ft<x<10 ft

25) 9 m<x<31 m

26) 2 km<x<14 km

27) 13 in<x<61 in

Step-by-step explanation:

It has to be greater than the difference and smaller than the sum.

22) 7-4=3, 4+7=11, so the answer is 3<x<11

23) 8<x<26

24) 0<x<10

25) 9<x<31

26) 2<x<14

27) 13<x<61

Answer:

45

Step-by-step explanation:

25 ÷ 45 = 0.555 x 81 = 45

Answer:

A 45-foot tree will cast a 81-foot shadow.

Step-by-step explanation:

Set up a proportion.

I'll set mine up like this:

[tex]\frac{Height of Tree}{Shadow}=\frac{Height of Tree}{Shadow}[/tex]

Insert the values given then solve for the unknown (t).

[tex]\frac{25}{45}=\frac{t}{81}[/tex]

[tex](81)\frac{25}{45}=\frac{t}{81}(81)[/tex]

[tex]45=t[/tex]

Answer: y=210000(1+0.02)^5

y=231856.97

Step-by-step explanation:

210000 is the total cost and it increases by two percent and its asking how much it will be in 5 years so when you plug in the equation you should get y=231856.97.

Answer:

The last one is incorrect

Step-by-step explanation:

Answer:

Step-by-step explanation:

For reference the quadratic equations looks like this

(-b±[tex]\sqrt{b^2-(4*a*c)}\\[/tex])/2a

Amy's mistake (and solution)

We can see that when amy mulitplied c she wrote 20 instead of -20 (in step 1). She can fix this by writing (4*1*-20) instead

Richard's mistake (and solution)

When richard messed up on step 5 when he wrote (6-2i)/2. You only would write the i if the negative was in the radical (but in this case it's outside). You would fix this by just getting rid of the i entirely (and keeping the 2)

I'm not really too sure how you would do three but I'll give it a shot anyways

our equation will look like this: x²+2x

which means our quadratic equation would look like this

[tex]\frac{-2+/-\sqrt{2^2-4*1*0}}{2}\\=\\\\\frac{-2+/-(2)}{2}\\\\\\= -1+/-(1)\\\\-1+1=0\\-1-1=-2[/tex]

When I write +/- I mean plus or minus giving us -2 and 0 as our solutions
