Problem 2: Raylin wants to buy a new bike for $85. She already has $22 saved and her mom will
give her $2.50 for each chore she does. What is the least amount of chores Raylin must do in order
to save enough money to buy the bike?
Answer
22
23
24
25
26

Answers

Answer 1
○=> Correct option :[tex]\color{plum}\tt\bold{(d) \: 25}[/tex]○=> Steps to derive correct option :

Cost of a bike Raylin wants to buy = $85

Money Raylin already has = $22

Money she needs :

[tex] = \tt85 - 22[/tex]

[tex] = \tt\$63[/tex]

Thus, money Raylin still needs = $63

Money she gets from doing one chore = 2.50

Number of chores the needs to do :

[tex] = \tt \frac{63}{2.50} [/tex]

[tex]\color{plum} =\tt 25 \: chores[/tex]

Thus, Raylin needs to do 25 chores to be able to buy the bike.

Therefore, the correct option is (d) 25

Answer:

x = 7

All 8 angles measure 135°

Step-by-step explanation:

(n-2)·180 = (8-2)·180 = 1,080°; this is the total of all interior angles

each angle is equal so we can divide 1080 by 8 and find that each angle measures 135°

to solve for 'x':

16x + 23 = 135

16x = 112

x = 112/16

x = 7

check:  16(7) + 23 = 135

             112 + 23 = 135

             135 = 135

Katherine has a fish tank shaped like a triangular prism in her living room. The triangle that forms the base of the tank has a base of 24 inches and a height of 20 inches. The entire tank is 36 inches tall. What volume of water is needed to fill the tank if the tank is only filled to 6 inches below the top?

Answers

Answer:

[tex]Volume = 7200in^3[/tex]

Step-by-step explanation:

Given

[tex]B = 24[/tex] --- base of the tank base

[tex]h = 20[/tex] --- height of the tank base

[tex]H = 36[/tex] --- height of the tank

Required:

Determine the volume of water needed for 6 inches below the top

First, calculate the area of the tank base.

[tex]Area = \frac{1}{2}Bh[/tex]

[tex]Area = \frac{1}{2}*24*20[/tex]

[tex]Area = 12*20[/tex]

[tex]Area = 240[/tex]

If the tank is filled 6 inches below the top, this means that the height of the water is H - 6.

So, the volume is:

[tex]Volume = Area * (H - 6)[/tex]

Substitute 240 for Area and 36 for H

[tex]Volume = 240 * (36 - 6)[/tex]

[tex]Volume = 240 * 30[/tex]

[tex]Volume = 7200in^3[/tex]

-3r+5r=2r
This is the right answer

Answer:

2r

Step-by-step explanation:

2r is the answer because:

We have to switch the -3r in to +3r and positive + positive = positive.

Then we change the add sign in to subtracting sign and we subtract:

3r-5r and  it will give us:

2r

And we keep the answer positive  because our answer was a +5r so the bigger number keeps the sign  the same.

Caleb and Suzanne each have a pile of blue and white chips. Caleb determines in his pile,three out of every four chips is blue. Suzanne determines in her pile, one out of every five chips are blue. How many total chips does each student have if Caleb and Suzanne each have 6 blue chips?

Answers

Answer:

Total number of chips Caleb have = 8

Total number of chips Suzanne have = 30

Step-by-step explanation:

In Caleb case -

Three out of every four chips is blue

⇒ If Caleb has total chips = 4

Then Blue chips = 3

⇒White chips = 4 - 3 = 1

Now,

If Caleb have 6 blue chips

⇒3 Blue chips = 4 total chips

  1 Blue chip = [tex]\frac{4}{3}[/tex] total chips

⇒6 blue chips = [tex]\frac{4}{3}[/tex] ×6 = 4×2 = 8 total chips

∴ we get

Number of chips become = 8

In Suzanne case -

One out of every five chips are blue.

⇒ If Suzanne has total chips = 5

Then Blue chips = 1

⇒White chips = 5 - 1 = 4

Now,

If Suzanne have 6 blue chips

⇒1 Blue chips = 5 total chips

⇒6 blue chips = 5×6 = 30 total chips

∴ we get

Number of chips become = 30

If = 58° and m = 120 in, what is the value of p to the nearest tenth of an inch?

Answers

Answer:

141.5 in

Step-by-step explanation:

sin 58 = m/p = 120/p

120 = psin58

120/sin 58 = p

p = 141.5 in.

Another way to look at this problem is to remember that the hypotenuse of a right triangle is the longest side.  Since 141.5 is the only answer greater than 120, it would have to be the logical choice for the length of p

Answer:

[tex]-\frac{1}{55}[/tex]

Step-by-step explanation:

Hi! Ace here.

Whenever we have a positive being added to a negative, we can just do the positive subtracted my negative.

So let's rewrite this:

[tex]\frac{4}{5} -\frac{9}{11}[/tex]

When subtracting and adding fractions, we have to make sure there is a common denominator, and if there isn't a common denominator, then we make a common denominator. The LCM, in this case, is 55, so let's convert the fractions.

[tex]\frac{4}{5} *\frac{11}{11} =\frac{44}{55}[/tex]

[tex]\frac{9}{11} * \frac {5}{5} = \frac{45}{55}[/tex]

Since [tex]\frac{11}{11}[/tex] and [tex]\frac{5}{5}[/tex] both equal 1, the fraction is the same value.

Now we subtract normally with our "new" numbers.

[tex]\frac{44}{55}- \frac{45}{55}[/tex][tex]=-\frac{1}{55}[/tex]

I hope this helped, let me know if you have any questions.
