Jake has 900 cm³ of material. He uses 14.5 cm³ to make a right triangular prism. He wants to make a second prism that is a dilation of the first prism with a scale factor of 4.
How much more material does Jake need in order to make the second prism?

Select from the drop-down menu to correctly complete the statement.

Jake needs an additional (13.5, 28, 42.5)
cm³ of material to make the second prism.

Answers

Jake needs an additional 42.5 cm³ of material to make the second prism.

Amount of material available

Since Jake has 900 cm³ of material and he uses 14.5 cm³ to make a right triangular prism. The amount of material available to make the second prism is V = 900 cm³ - 14.5 cm³

= 885.5 cm³

Scale factor

Now, the second prism is gotten by ditaion of the first prism by a factor of 4.

Since we have volume, (scale factor)³ = volume of second prism/volue of first prism

Volume of second prism

So, volume of second prism, V' = (scale factor)³ × volume of first prism = 4³ × 14.5 cm³ = 928 cm³

Amount of material more needed

So, the amount of material more needed to make the second prism is V"' = V' - V = 928 cm³ - 885.5 cm³

= 42.5 cm³

So, Jake needs an additional 42.5 cm³ of material to make the second prism.

a cast member is selling balloons on main street. he has 4 princess balloon, 5 blue mickey balloons and 1 red mickey balloon. he sells 1 balloon and then another (no replacing). find the probability of selling one blue balloon followed by another blue balloon.

Answers

Answer:

hee-hee!

Step-by-step explanation:

We first have to find how many possible outcomes there are.

We find that out by seeing how many types of balloons are in total.

4 + 5 + 1 = 10

There are 10 possible outcomes.

We then see how many favorable outcomes there are.

There are 5 blue mickey balloons.

That means 5/10 or 1/2.

Then we subtract 1/10 from 5/10.

5/10 - 1/10 = 4/9

We lower the denominator by 1 because the total possible outcomes are also lowered by one.

The probability of the cast member selling another blue balloon after selling the first one is 4/9.

hope this helps :)

How many quarts of pure antifreeze must be added to 3 quarts of a 10% antifreeze solution to obtain a 60% antifreeze solution?
Round to nearest tenth if possible

Answers

Answer:

3.75 quarts, rounded to 3.8 quarts

Step-by-step explanation:

3 quarts of solution is 10% antifreeze, so 0.3 quarts are already antifreeze, and 2.7 quarts are not.

a(the antifreeze we already have)+x(what we're going to add)= 1.5*2.7

Let me explain. If we have 60% antifreeze, 40% is not. 60/40=1.5

Substitute a for 0.3

0.3+x=4.05 Subtract 0.3 from both sides

x=3.75

A truck drove 208 miles on 5 gallons of gas. How far should it be able to go on a full, 11-gallon tank?

Answers

Answer:

457.6

Step-by-step explanation:

if he drove 208 on 5 gallons, 208/5 =41.6 miles per gallon. 41.6*11= 457.6

Answer:

457.6 miles

Step-by-step explanation:

So 208 miles equals 5 gallons so if you add 208 two times you will already have used 10 gallons and that equals 416 miles so far. So now you have to divide 208 by 5 and that equals 41.6 so 416 plus 41.6 equals 457.6 miles

Answers

Answer:

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:

See below.

Step-by-step explanation:

Let's review the metric prefixes used in this problem:

m = 1/1000

h = 100

c = 1/100

k = 1000

da (deca) = 10

20 hm = 20 × 100 m = 2,000 m

3,412 mm = 3412/1000 m × 1 km/(1000 m) = 0.003412 km

0.25 m = 0.25 m × 1000 mm/m = 250 mm

590 mg = 590 mg × 1 g / (1000 mg) = 0.59 g

75 cm = 75 × m/100 = 0.75 m

12.5 m = 12.5 m × 1 km / 1000 m = 0.0125 km

8,808 cm = 8,808 cm × 1 m / 100 cm × 1 km / 1000 m = 0.08808 km

20 hm = 20 × 100 m × 1000 mm/m = 2,000,000 mm

1,235 g = 1,235 g × kg/(1000 g) = 1.235 kg

12 dm = 12 dm × 1 m / 10 dm × 1 dam / 10 m = 0.12 dam

20 L = 20 L × 1000 mL/L = 20,000 mL

13.6 mL = 13.6 mL × 1 L / 1000 mL = 0.0136 L

Step-by-step explanation:

1) 7.5 miles north-east

2) 8 cubic inches

3) x = 6.24

Step-by-step explanation:

1) Use pythagorus thereom:

a² + b² = c²

4.5² + 6² = c²

20.25 + 36 = c²

c = √56.25

c = 7.5

7.5 miles north-east

Surface area = 24

Cube has 6 sides

24 / 6 = 4

1 side = 4

1 length = √4

N = 85

Step-by-step explanation:

(236 + 542)+N = 863

778 + N = 863

N = 863 - 778

N = 85

Answer:

N=85

Step-by-step explanation:

(236 + 542) + N = 863

Go in order of PEMDAS (Parantheses, Exponents, Multiplication, Division, Addition, Subtraction)

236 + 542= 778

now we have

778+N = 863

(778 plus a number equals 863)

to find the number (N) we can subtract 778 from 863.

863-778=85

so,

N = 85
