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
The length of line segment AD is 6.8 cm. The length of line segment AB is 3 cm. The length of line segment BC is 1.6 cm. Find the length of line segment CD.
Answer:
9.6
Step-by-step explanation:
This is a four side figure which is most likely to be a trapezium.So AD is the hypotenuse,AB is side (a),BC is the height and CD is side (b).

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.

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.
Jake needs an additional 42.5 cm³ of material to make the second prism.
Amount of material availableSince 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 prismSo, volume of second prism, V' = (scale factor)³ × volume of first prism = 4³ × 14.5 cm³ = 928 cm³
Amount of material more neededSo, 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.
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.

0.25 m = 250 mm
590 mg = 0.59 g

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
Which scenarios can be represented by a ratio of 4 : 5 ?
There are 8 apples and 10 oranges in a basket. In this scenario, we can see that ratio of apples to oranges is 4:5.
What is the ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
A ratio is a fraction that may compare part to whole or part to part. For example, suppose in a class, the ratio of boys to girls is 4 to 5. It means that the number of boys divided by the number of girls is a fraction that, in its simplest form, equals 4 over 5.
Same as there are 8 apples and 10 oranges in a basket. this is also represented perfectly in terms of ratio.
Therefore, In a basket, there are 10 oranges and 8 apples. We can observe that the ratio of apples to oranges in this situation is 4:5.

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
