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

Answer:

Percent: 140, 275, 0.08

Fraction: 16/25, 1 2/5, 2/25

Decimal: 0.64, 12.5, 0.125, 2.75

Step-by-step explanation:

0.08 = 8%

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

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

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

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

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.

Answer:

42.5 cm³ for K12

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:

Step-by-step explanation:

20 hm = 2000 m

3,412 mm = 0.003412 km

0.25 m = 250 mm

590 mg = 0.59 g

75cm = 0.75 m

12.5 m = 0.0125 km

8,808 cm = 0.08808 km

20 hm = 2000000 mm

1,235g = 1.235 kg

12 decimeters = 0.12 dam

20 L = 20000 mL

13.6 mL = 0.0136 L

Hope this helps :)

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

Answer:

1. = 7.5

2. = 8 inches

3. =  x=3

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

2) The ice is a cube,

Surface area = 24

Cube has 6 sides

24 / 6 = 4

1 side = 4

1 length = √4

1 length = 2

Volume = bhd

Volume = 2³

Volume = 8 in.³

3) ⅓x³ = 9

⅓x = (3√)9

⅓x = 2.08

x = 2.08 / ⅓

x = 6.24

Answer:

m1=125 degrees

m2=55 degrees

m3=55 degrees

m4=125 degrees

m5=125 degrees

m6=55 degrees

m7=55 degrees

Step-by-step explanation:

becoz the image thing says m8 is 125 degrees

and that just gave us the answer for measures 5, 4, and 1 because a is parallel to b so thats why you can see that all of the measures are all the same

now for 2, 3, 6, and 7 we needa find those righht?

remember full circle is 360 degrees and we know measures 4 and 1 is 125 degrees,

so all we gotta do is add them which is 250 degrees and subtract from 360 degrees

360-250 = 110 degrees

ok now divide by 2 since were lookink for 2 and 3 not 2 and 3 combined

110/2=55 degrees

and boom all of those angles are the same for 5, 6, 7, and 8

Answer:

$0.50/muffin

Step-by-step explanation:

To find the unit rate we have to find out how much 1 muffin costs:

To do this we can divide both sides by 7:

7÷7 for 3.50÷7

1 muffin for 0.50

Therefore our answer is $0.50/muffin

Answer:

$0.50 / muffin

Step-by-step explanation:

7 muffins for $3.50

To find the unit rate, we need to find what 1 muffin costs.

so

1 muffin = 3.5/7 = 0.5

$0.50 per muffin.

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

Answer:

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
