Which answer option shows the correct placement of the parentheses to make this a true number sentence? 8 + 4 ÷ 2 = 6

Answers

Answer 1

(8+4)/2=6 would be the correct placement of the parentheses.

Answer 2

The correct placement would be (8+4) divided by 2 = 6. I don't have the division key on my device. In addition, the sum of 8 and 4 is 12. Then 12 divided by 2 is 6.

B. x = 67, y = 46
C. x = 67, y = 134
D. x = 23, y = 46

Answers

B; since we know that angle NKL is 90° and is cut by a diagonal line that angle NKM is 67° since angles MKL and NKM both form a right angle. With this information we could now say that x is 67°, because angles NKM and LMK are alternate interior angles, stated in the alternate interior angles theorem. One of the properties of a parallelogram is that diagonal bisect each other, making all the bisected diagonal congruent, so we could use this information to find y. In the picture you could see highlighted in red the diagonals I will be focusing on. Since these two diagonals are congruent, but not the base side, this makes the shape of an isosceles triangle. We know that isosceles triangle's base angles are congruent, so we have to make label the base angles both 67°. Because of the Triangle Sum Theorem, the triangle has to equal 180°, so we add the base angles to get 134°, then we have to subtract 180° and 134° to get 46°, which is your y.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

If a jogger runs 2 kilometers and burns 185 calories, he or she.

Then the number of calories that jogger can burn per mile is given as,

⇒ 185 / 2

⇒ 92.5 calories per mile

The number of calories when he burns jogging 3 miles will be

⇒ 92.5 x 3

⇒ 277.5 calories

The number of calories when he burns jogging 3 miles will be 277.5 calories.

20(−1.5r+0.75) expand the expression and combine like terms

Answers

20(−1.5r + 0.75)

here, you need to distribute the "20" to the inside of your parentheses. you'll be multiplying 20 and -1.5 first:

-30r

then 20*0.75 second:

-30r + 15 is your expanded expression. you can't combine like terms any further.

Answer:

-30r + 15

Step-by-step explanation:

We have been given that

20(−1.5r+0.75)

Use the distributive property a(b+c)=ab+ac.

20×(−1.5r)+20×0.75

Multiplying, we get

-30r +15

These two are not like terms. Hence , we cannot combine them.

Therefore, we cannot simplify it more.

Hence, the simplified expression is -30r + 15

Final answer:

To find the number of cats at the pet store, set up a proportion using the given ratio of dogs to cats and the number of dogs. Cross multiply to solve for the number of cats.

Explanation:

To find the number of cats at the pet store, we need to use the given ratio of dogs to cats. Since the ratio is 1:2 and there are 15 dogs, we can set up a proportion to solve for the number of cats. We can write the proportion as 1/2 = 15/x, where x represents the number of cats. We can cross multiply to find x, which gives us x = 30. Therefore, there are 30 cats at the pet store.

3/5 pt of juice is poured into 6 glasses.How much juice is in each glass?

Answers

Each glass contains 1/10 pt of juice when 3/5 pt of juice is evenly divided into 6 glasses.

To determine how much juice is in each glass when 3/5 pt of juice is poured evenly into 6 glasses, one must divide the total amount of juice by the number of glasses. This is a basic division problem often encountered in converting customary units in real-world situations.

First, convert the pint (pt) measurement to a more convenient unit if needed. In this case, we can keep it in pints since the division is straightforward. Next, divide the 3/5 pt of juice by 6.

Calculate the amount of juice in each glass: 3/5 ÷ 6 = 3/5 × 1/6 = 3/30 = 1/10.

Convert the fraction to pint measurement if necessary: 1/10 pt.

So each glass would contain 1/10 pt of juice.

Kareen correctly answered 85% of the questions on his last math test. If he missed 6 problems, how many questions were on the test?

Answers

He got 85% correct, which also means he got 15% wrong (the 6 problems)

This means 6=15%

15 does not go into 100 evenly, but 5 does. And 3 happens to be a common factor for both 6 and 15. If you divide both sides by 3 you get:
2=5%

Now we need to find 100%. If 5% of the test is 2 questions, then 100% must be 40.

It's like solving proportions-

2:5
x:100

5 to 100: multiply by 20

2 to x: also multiply by 20

2 times 20 = 40 = 100%

The total number of questions on the test is 40 (questions).

28 because if you divide 49 by 7 you would get 7 and then multiply it by 4. Then you get the answer of 28.

Yes, she multiplied 24 (the hours in a day) by 7 (days in a week), and the answer is 168.

would a field with a width 75 yards and an area of 7500 square yards be within FIFA regulation?why or why not.

Answers

Final answer:

Yes, a field with a width of 75 yards and an area of 7500 square yards would be within FIFA regulation.

Explanation:

The area of a rectangle is calculated by multiplying its length by its width. In this case, the width of the field is 75 yards and the area is 7500 square yards. To determine if the field is within FIFA regulation, we need to compare its area to the typical dimensions of a soccer field.

A typical soccer field has a length of 100-130 yards and a width of 50-100 yards. Since the field in question has a width of 75 yards, it falls within the acceptable range. Therefore, the field with a width of 75 yards and an area of 7500 square yards would be within FIFA regulation.

14. The percentage of change from 35 birds to 45 birds is 59%.

17. 1/6 years.

18. 1/4 years.

19. 1/3 years.

20. 1/2 years.

What is a percentage?

In Mathematics, a percentage is any number that is expressed as a fraction of hundred (100).

Part 14.

Mathematically, percentage increase can be calculated by using the following mathematical equation:

Percentage increase = (Final value - Initial value)/Initial value × 100

Percentage increase = (45 - 35)/35 × 100

Percentage increase = 10/35 × 100

Percentage increase = 28.57 ≈ 29%.

Part 15.

Mathematically, percentage decrease can be calculated by using the following mathematical equation:

Percentage decrease = (Final value - Initial value)/Final value × 100

Percentage decrease = (60 - 38)/60 × 100

Percentage decrease = 22/60 × 100

Percentage decrease = 36.67 ≈ 37%.

Note; 1 year is equal to 12 months.

In order to express each number of months in years, we would divide the number of month by 12;

Part 17.

Time = 2/12

Time = 1/6 years.

Part 18.

Time = 3/12

Time = 1/4 years.

Part 19.

Time = 4/12

Time = 1/3 years.

Part 20.

Time = 6/12

Time = 1/2 years.
