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).
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.

20 L = mL
13.6 mL = L
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

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

A bakery sells 7 muffins for $3.50. What's the unit rate? $2/muffin $0.50/muffin $0.70/muffin $3.50/muffin
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.

can someone please help me
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.

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
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

3. solve 1/3x^3 = 9
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

3. Find Each Angle Measure
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
