Answer:

40

Step-by-step explanation:

Two ways we can solve this problem:

1. Graphically

2. Mathematically

Because you already solved it graphically, I will show you how to do so mathematically. Of course, graphically is much much easier and more efficient in this problem.

Let's break the problem down.

First, we are given a graph which contains a slope.

To find slope, we use the technique -> rise/run

Picking 2 obvious points from the graph, we can see

1st point -> (10, 20)

2nd point -> (40, 80)

Now, let's find the slope

[tex]\frac{80-20}{40-10} = \frac{60}{30} = 2[/tex]

Now, we have an equation y = 2x, where y = number of pies and x = cups of sugar

We want to find how many cups of sugar we need to bake 80 pies. Simply substitute 80 = number of pies = y

y = 2x -> 80 = 2x

Solving for x, divide both sides by 2

40 = x

We need 40 cups of sugar.

Answer:

6/41

Step-by-step explanation:

6 + 7 + 20 + 8 = 41 so that is number of tiles he took. 6 of those were 41 so therefore, the chance is 6/41

Answer:

There are four red marbles and six blue marbles in all, for a total of ten marbles.

Without replacement, the probability of the first marble being blue is 6/10, while the probability of the second marble being red is 4/9.

The probability of both events occurring is reduced to 4/15 by multiplying 6/10 * 4/9 = 24/90.

Answer:

19 inches

Step-by-step explanation:

Since the blue ribbon needs to be 7 inches longer than the red ribbon, add 7 to 12 to get 19 inches total.

Hopefully this helps- let me know if you have any questions!

Hey there!

Let's make an equation 28evbar01

=> Convert word problem into equation

7 - x = 12

x = 12 + 7

x = 19

Therefore, Blue ribbon is 19 inches

Answer:

240÷3.00=710

Answer:

Im pretty sure its C... Step-by-step explanation: what im seeing here is 10 with the small numbers in front so it looks like scientific notation, Maria has 1 million because 1 x a number = that number, 10 multiplied by itself 6 times equals 1 million, 10 x10 = 100 x 10 = 1000 x 10 = 10,000 x 10 = 100,000 x 10 = 1,000,000. so from this we know what Larry's 10 to the power of 5 is, we need to know what 100,000 x whatever equals. If im doing this right, Larry's number is 1 million 2 hundred thousand which is greater than 1 million. (sorry if the explanation is wanky and sorry if it was wrong, im new to brainly.)

Answer:

y ≤ 0

Step-by-step explanation:

y ≤ 0

< or >: dashed line

≤ or ≥: solid line

≤ or <: shade below the line

≥ or >: shade above the line

Here we have:

a solid like (possibilities: ≤ or ≥)

shades below the line (≤)

Final answer, y ≤ 0

Hope this helps!

Answer:

The inequality is D) y is less than or equal to 0

Step-by-step explanation:

The yellow shaded area is on the 0 line and below it, making it less than or equal to 0.

Answer:

546

Step-by-step explanation:

Sofia slept 546 miles and was awake for 45% which is 294 of the miles.

You can find this by finding 1%, and that would be 8.4. (You get 1% from dividing 100 from the 100% number.) Then you multiply it by 65 so now you get 546.

If the total length of the trip was 840 miles, then Sofia had traveled 294 miles before she fell asleep.

Given that,

If Sofia slept through the last 65% of the trip and the total length of the trip was 840 miles,

then she stayed awake for the first 100% - 65% = 35% of the trip.

Here, we have to calculate the distance she traveled before falling asleep, we can use the percentage of the total distance:

Distance traveled by Sofia = 35% of 840 miles

Distance traveled by Sofia = 0.35 * 840

Distance traveled by Sofia = 294 miles

So, Sofia had traveled 294 miles before she fell asleep.

Answer:

The triangle and the square have the same area because they both have four squares

Step-by-step explanation:

The square has four that are easily shown but the triangle has one full one but when two are split together like some of them when you put the two together they equal one whole.

CAB

Step-by-step explanation:

12x - 6 = 10

divide both sides by 2

6x - 3 = 5

add 3 to both sides

6x = 8

multiply both sides by 1/6

x = 4/3

Answer:

hee-hee!

Step-by-step explanation:

We know that the circles diameter is 15 mm. We can tell that by looking at the side of the rectangle. It says 15 mm.

Either way, we use the formula to find the area of a circle:

A = [tex]\pi[/tex]d

A = (3.14)(15)

A = 47.1

The area of the circle is 47.1. (i think?)

sowwy if it took long

Answer:

426.45 mm

Step-by-step explanation:

find the area of the circle by multiplying the radius by pi(3.14) then you would subtract that from the area of the rectangle. Hope this helps

Answer:

Fractions have different applications in the real word. We can interpret them as parts of a whole in recipes, sports team performance, test scores, time, and pizza slices in a pie. They can also be interpreted as decimals and percentages.

Step-by-step explanation:

Hope this helps!

All the correct methods to interpret fractions is,

Fractions as parts of wholes or parts of sets;

Fractions as the result of dividing two numbers;

Fractions as the ratio of two quantities;

Fractions as operators; and fractions as measures.

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

To find the method for interpret fractions.

Since, Fractions have different applications in the real word.

Hence, We can interpret them as parts of a whole in recipes, sports team performance, test scores, time, and pizza slices in a pie.

Step-by-step explanation:

To do this you need to simplify (4^3)^5

To do this, simply multiply the powers

So, it would be 3x5
