0 In 20-25, insert parentheses to make each statement true. 20. 30 - 4 X 2 + 5 = 2 21. 17 – 8 – 5 = 14 22. 10 = 2-3 + 1 = 3 23. 30 – 4 x 2 +5= 57 24. 17 – 8 – 5 = 4 25. 10 = 2-3 + 1 = 1
I need to know where to place the parentheses but my teacher didn't explain it well enough for me.
Answer:
This is pretty much trial and error,
Step-by-step explanation:
what you are doing is trying to make the question true. So if you're trying to make 30 - 4 x 2 + 5 =2 true, you need to try to put parentheses in the right place, because Wwhatever you see in parentheses you have to do first. For example, the answer to the first question is 30 - 4 x (2+5) =2. The reason is 2 + 5 = 7, and 7 × 4 = 28, and 30 - 28 is 2. To help with order of operations, remember the term Please Excuse My Dear Aunt Sally (P for parentheses, E for exponent (if you're here yet), M for multiplication, D for division, A for addition, and S for subtraction). Here are the other answers:
17 - (8 - 5) = 14
(30 - 4) × 2 + 5 = 57
17 - 8 - 5 = 4

A person runs 1/8 mile in 1/64 hour.
The person's speed is (BLANK) miles per hour.
Answer: The person's speed is 8 miles per hour.
Step-by-step explanation:
To solve we want to convert the [tex]\frac{1}{8}[/tex] and [tex]\frac{1}{64}[/tex] proportionally for the number of miles per hour. We know that multiplying a fraction by its reciprocal will equal 1. So let's do that for the value of the hour.
[tex]\frac{1}{64}[/tex]×[tex]\frac{64}{1} =\frac{64}{64} =1[/tex]
Since we multiplied that to the number of hours we must also do that for the number of miles.
[tex]\frac{1}{8}[/tex]×[tex]\frac{64}{1} =\frac{64}{8} =8[/tex]

How do I explain this to my sibling?
Answer:
1. Multiply the number of candies sold by 8
2. Multiply the number of servings by 20
Step-by-step explanation:
Hello!
Question 1.We can approach this problem by looking at the first column in Question 1.
We can see that 10 is multiplied by 8 to get to 80, and 20 is multiplied by 8 to get to 160. We can assume this is a pattern because it repeats twice.
So we multiply by 8 for the first question.
Question 2.We see that for every increase of 30 servings, the pretzels increase by 600.
We simply divide 600 by 30, to find our multiplier of 20.
So we multiply by 20 for the second question.
Calculate the financial cost of a tobacco addiction. How much would it cost to buy two packs of cigarettes every week for one year? What else could you purchase with this amount of money?
Answer:
According to the National Cancer Institute, the average cost of a pack of cigarettes is $6.28, which means a pack-a-day habit sets you back $188 per month or $2,292 per year.
So we times that by two which would be $4,584 a year.
With this amount of money you could purchase a stocks, jewlery, car, or anything else that is under that amount.

A dart hits the circular dartboard shown below at a random point. Find the probability that the dart lands in the shaded square region. The radius of the dartboard is 14in, and each side of the shaded region is 5in. Use the value 3.14 for π. Round your answer to the nearest hundredth.
Answer:
The first thing you need to do is, have a square whose area is 11² = 121 square inches. Then we are going to multiply the radius by π which is 3.14 the area of the circle with the radius 4 is equal to 3.14 × 4² = 3.14 × 16 = 50.24, you need to divide the calculated radius times π (3.14) you can get the answer and you need to round your answer to the nearest hundredth probability that the dart will hit within the circle is equal to 50.24 ÷ 121 = 0.4152066116 which is rounded to 0.04152 or 41.52% this assumes the dart will always hit the square at least.

first put them in sequential order so it would be
10, 10, 15, 15, 16, 18, 23
okay Then, divide the sequence into the 1st and 3rd quartiles. the median would be 15 becuase it is the middle.
1st - 10
3rd - 18
then you subtract
18 - 10 = 8

Find the area of the window shown below. Use 3.14 for pi. Round to the nearest tenth.
Answer:
A = 22.0 in²
Step-by-step explanation:
The area-of-a-circle formula is A = (pi)r², where r is the radius. The area of a semicircle is A = (1/2)(pi)r².
In this case (semicircular window), the area is
A = (1/2)(3.14)(14 in) = 21.98 in². To the nearest tenth, that's A = 22.0 in²

Given: PQ || Hl. Find the length of GH. . A 23 B 26 C 28 D 30 help pls it time
n
Answer:
B) 26
Step-by-step explanation:
Finding PH
Take the sides in proportionGP/PH = GQ/QI10/PH = 15/2410/PH = 5/8PH = 10/5 x 8PH = 16Finding GH
GP + PH10 + 1626If PQ || HI, then the value of GH obtained will be equal to 26. Hence, option B is correct.
What is ratio?The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities in order to compare them.
As per the given figure in the question,
Firstly, we have to find the value of PH.
Take the sides in proportion from the given figure,
GP/PH = GQ/QI
= 10/PH = 15/24
⇒ 10/PH = 5/8
PH = 10/5 x 8
PH = 16
Now, the value of GH will be,
GP + PH
= 10 + 16
= 26

Knowing the surface of an object would be useful for:
- the amount of paint needed to paint a room
- how much wrapping paper a gift will need
What is Surface Area?
Surface area is the total area covering the outside of a 3D shape.
By knowing this number, we can count the amount of paint needed to paint a room, how much wrapping paper a gift will need, etc.
On the paint pail, we can find the information about its coverage. for example: 1 liter of paint will cover 6 m2 of wall. When we know the area of wall, we can count the pail needed.Once we know the area of the wrapping paper area and the gift’s surface, we can count the wrapping paper needed.On the other side, when we talk about the amount of water needed to fill an aquarium, how many watermelons fit in a box for shipping, the amount of gasoline left in the tank of vehicle, etc. we have to know the volume of the related variables.
