There were 25 problems in Mark's test. 92% of the problems he answered correctly. How many wrong answers were in Mark's test?

Answers

Answer 1

Answer:

2 incorrect answers

Step-by-step explanation:

If you take the percentage correct, you will notice its a particularly high score for the amount of questions. In this case, instead of using a really long theorem, its much simpler to just input numbers.

To find your score on a test out of 100%, you take your amount correct and divide it by the total number of questions, then multiply by 100.

If you take 24/25, you get 0.96, which if multiplied 100*0.96=96%

Now its simple, just go 23/25 to get 0.92, multiplied 100*0.92=92% correct, 25-23=2 so the amount of incorrect answers would be 2.

Robert is baking desserts for a picnic. He needs to make at least 20 servings of dessert for the
event. For every batch of brownies he bakes, he will get 8 servings, and every pie will
yield 14 servings.

Answers

Answer:

x*8 + y*14 ≥ 20

Step-by-step explanation:

We know that:

A batch of brownies makes 8 servings.

A pie makes 14 servings.

He wants to make, at least, 20 servings.

Then if he makes x batches of brownies, he will get x times 8 servings.

If he makes y pies, he will get y times 14 servings.

Adding that, he will get a total of:

x*8 + y*14 servings

And because he wants to make at least 20 servings (he can make 20 or more)

The inequality will be:

x*8 + y*14 ≥ 20

Where the "≥" symbol means that the expression at the left is greater than or equal to the expression of the right

Answers

Step-by-step explanation:

1. 1/5 = 0.2 or 20%

2. 1/8 = 0.125 or 12.5%

3. Noah is more likely to select 'E' because he has a higher percentage or probability of selecting it. 0.2 is greater than 0.125

The table shows information about the type and number of sandwiches ordered by 80 customers. If 120 customers order a sandwich, how many would you expect to order a club?​

Answers

Answer:

54

Step-by-step explanation:

80 Customers divide that by 2 =40

36÷2= 18

So if 120 Customers were to order then you would just add 18 to 36 and that would make it 54.

Basically just find how many clubs are bought in 40 customers then multiple it by 3

One box of strawberries cost $5. Which equation can be used to calculate the most number of boxes a person can buy with $307 30 =5n 30 = 5+n 5 = 30 5 = 30 + in​

Answers

Answer:

30 = 5n

n = 6

Step-by-step explanation:

A box of strawberry cost = $5

A person has = $30

Number of boxes a person can buy = n

Equation to calculate the most number of boxes a person can buy with $30

Amount with the person = cost of a strawberry × number of strawberry

30 = 5 * n

30 = 5n

n = 30/5

n = 6

The triangle is an isosceles triangle as shown with the lines on the sides of the triangles. That means the unknown angle is 35 degrees since angle Q cannot be 35 degrees. Solve the equation:

2x + 80 = 180

2x = 100

x = 50

Can I have Brainliest?

X is 50

The triangle in the picture is an isosceles triangle, that means two of the sides are equal. An isosceles triangle has two equal sides, therefore it also has two equal angles. That means that side QR is equal to QP, which also means that point P and point R have equal angles. We know that the angles in a triangle must always add up to 180°. We already know the information for angle R and angle P so we can add those together, this gets us 70°. We can now build an equation with the information we have: 2x + 10 + 70 = 180. Solve the equation and you’ll have your final product, x = 50.

It is growth that hurts the ego that stings. Each transformation is painful because the old situation is being left behind for the new. For example when a relationship ends we feel hurt ur hopes and dreams have crashed and u feel lost and lonely wondering what comes next. i always ask myself is love worth the pain and for a long time i shut myself out saying no its not worth it that gettin hurt over lose is useless but i soon came to see that love is worth the pain but if pain is all you seem to receive in any relationship than that love is one-sided. Love is going to hurt at some point. it is worth the pain when it truly is love. When true love is in place, you find two people not one willing to give whatever is needed to make love last. i rlly wish i gave myself this advice a long time ago when i got hurt and kept going but i didnt now i can only hope that u wont make the same mistakes from me Ms. McClain conducted an experimentwith a 6-sided number cube.
