At a concert 6 out of the first 20 people who entered the
concert were wearing hats. Based on this information, if
there are 800 people at the concert, how many of these
people are expected to be wearing a hat?

Answers

Answer 1

Answer:

240 people

Step-by-step explanation:

6/20=x/800

800*6=20x

4800=20x

240=x

Therefore, you would expect 240 people to be wearing a hat

Answer 2
240 people because 6/20 is 30% and 240/800 is the same 30%

70

Step-by-step explanation:

An isosceles triangle has two equal sides, and the angles add up to 180 degrees. 180 - 70 - 40 = 100, therefore the answer is 70

The sum of the angles on ANY triangle will ALWAYS be 180°.

So,

40° + 70° +

Elise is making 42 chocolate ice cream sundaes. The number of quarts of ice cream she needs is directly proportional to the number of people served. Suppose it takes 3 quarts of ice cream to serve 18 people. Which statements are correct for this situation?

A) Elise needs 7 quarts of ice cream
B) Elise needs 6 quarts of ice cream.
C) The constant of proportionality is 1 /6.
D) The constant of proportionality is 6/ 1.
E) The constant of proportionality is 1/ 8.

Answers

Answer:

A (Elise needs 7 quarts of ice cream)

Step-by-step explanation:

Okay so we know that Elise is serving 42 people, since she's making 42 chocolate ice cream sundaes.

Since it takes 3 quarts to serve 18 people, we know that the amount of people divided by 6 will equal the quarts.

So 42 people divided by 6 equals 7 quarts.

The concentration of the mixture made by mixing 6 fl. oz. of a 20% alcohol solution and 4 fl. oz. of a 5% alcohol solutions is 14%

What is an equation?

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the concentration of the mixture, hence:

(6 * 20%) + (4 * 5%) = x * (4 + 6)

1.2 + 0.2 = 10x

x = 0.14 = 14%

Group the terms with variables on one side of the equal sign, and simplify.
8t −15 = 32t

Answers

Answer:

t = -5/8

Step-by-step explanation:

1.) Add 15 to each side canceling it out on the left

8t - 15 = 32t

    +15    +15

2.) Subtract 32 from each side canceling it on the right

8t = 32t +15

-32t  -32t

3.) Divide each side by 24 to get the variable

-24t = 15

-24t/-24t = 15/-24t

4.) Simplify by 3

5/-8

t = -5/8

Subtract 8t from 8t and then do 32t- 8t. The new equation is -15=24t. That is the new equation simplified. But the answer would be t=15/24, but you can simplify that which would be t=5/8

-3y

Answers

The second one.

Because 3y-7y = -10y and -8+9 = 1
-10y + 1
-10y + 1 because when you combine like terms 3y minus -7y because of the subtraction symbol in front so that equals -10y then -8 + 9 equals 1 so it’s -10y + 1

Multiply 5 x 8= 40 -the total of one triangle

5x3=15- the total measure of the circle top part

120+15= 135

ANSWER: 135

BRAINLIST??

Answer:

148cm²

Step-by-step explanation:

seriously why, just why? okay, hold on, we're gonna be here a while

Let's start with the triangles, they're all equal, and we already have their measurements and the formula for the area of a triangle is base x height ÷ 2, so all we have to do is plug:

5 x 8 = 40

40 ÷ 2 = 20

Now we have to multiply by 3 because there's 3 of these abominations:

20 x 3 = 60

So we put that on a back burner while we do the semicircle

So the formula for the area of a circle is pi x radius², so we have to find the radius. We know that each of the triangle bottoms is 5cm, so we just multiply by 3:

5 x 3 = 15

So the diameter of the semicircle is 15cm, now we divide that by two to find the radius:

15 ÷ 2 = 7.5

Now we just plug that into our formula (we're using 3.14 for pi)

7.5² = 56.25

3.14 x 56.25 = 176.625‬

Usually, we'd stop there, but it's only half of a circle, so:

176.625 ÷ 2 = 88.3125‬

So now we add both of our areas:

60 + 88.3125‬ =

148.3125‬

Normally, that would be the answer, but since we're supposed to be estimating, we round it to the nearest whole number:

148.3125 -> 148

So the area of the figure is 148cm²

if this is wrong, let me know so I can fix it

hope this helps:)
