Answer:
H=16 L1=3 L2=2
Step-by-step explanation: First, we need to brainstorm the multiples of 32 and 48, 16 comes to mind. Because 48 and 32 are both multiples of 16, one can determine that since 16x3 is 48 then L1, should be 3. Finally 16x2 is 32 so L2 must be 2.
Answer: 48 + 32 = 16 (3+2)
Step-by-step explanation:
Find the area of the whole rectangle:
48 + 32 = 80
Now things are more easier!let's just say that the length is 5 broken up and the height is 16
16 x 5 = 80
All we need to do is break it up correctly to fit make the totals 48 and 32.
16 x 3 = 48
16 x 2 = 32
In the end we get the equation:
48 + 32 = 16 (3+2)

Gunpowder contains 75% nitre and 10% sulfur. Find the amount of gunpowder which carries 9 kg nitre. What amount of gunpowder would contain 2.3 kg sulfur?
Answer:
Let the amount of gunpowder that contains 9 kg nitre be x kg. ∴ The amount of gunpowder containing 9 kg nitre is 12 kg.
So, about 200 kg gunpowder
Dialation of a triangle
Answer:
Whenever you want to zoom and enlarge a photo so you can see details, you are using a dilation transformation.
At eye exams, the pupil dilates (widens), allowing in more light and giving your doctor a better view of the back of your eye.
When you build model airplanes, cars, or buildings that are true in scale and measurement, you are performing a dilation.
And even your shadow is a dilation as well.
Step-by-step explanation:
Isabella buys a 1.75 litre carton of apple juice. What is the largest number of 200 millilitre glasses that she can have from the carton?
Isabella can have 8 full glasses and 0.75(3/4) glasses from the 1.75-liter carton of apple juice.
What is a fraction?Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
Isabella buys a 1.75-liter carton of apple juice.
To convert it to milliliter multiply it by 1000
1.75 liter in ml = 1.75×1000 = 1750 ml
Let's suppose the number of glasses she can have is x, so the value of x:
x = 1750/200 = 8.75 glasses.
Thus, Isabella can have 8 full glasses and 0.75(3/4) glasses from the 1.75-liter carton of apple juice.

A plant grows 3 centimeters in 10 days. How much does it grow per day? Write your answer as a fraction in simplest form.
Answer:
It grows 0.3 cm per day.
Step-by-step explanation:
Divide 3cm by the 10 days. [ 3 / 10 = 0.3 ]
Find the density of an object that has mass of 5kg and a volume of 50cm

Step-by-step explanation:
The easiest way too solve this si to split the shapes up into two smaller shapes. For the first one split it into two rectangles, the long rectangle and the smaller rectangle down the bottom right. First we will do the smaller rectangle, multiply 7 by 2 and then multiply that by 5-3 (the bottom length minus the top length) and you get 28. 7(7x3) + 28. This equals 175. Because it is volume the answer is cubic. Repeat theses steps for the other 3 questions and that is how you solve it.

Explanation:
We have these three rules for scale factors
scale factor > 1, enlarge the image0 < scale factor < 1, shrink the imagescale factor = 1, the preimage and image are identicalWith those rules in mind, we have enlargements for these transformations.
P to QP to RQ to RAll of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.
In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.
----------------
We also have these reductions
Q to SR to PThis is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.
----------------
And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.
P to SS to PThe order doesn't matter for this subset, but the order will matter for the other batches of transformations.

Step-by-step explanation:
If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525

Use the diagram of the equilateral triangle shown below to answer the following questions. Show the work that leads to your answers. a. What is the perimeter of the triangle? b. What is the height, ℎ mm, of the equilateral triangle? Write an exact answer using a square root and an approximate answer rounded to the tenths place.
Answer:
Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.
Step-by-step explanation:
The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.
For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.
I've enclosed an attachment for that.

x-2y=-4,:x=2y-4 Find the value of x and y
Answer:
x=-4+2y
x= 2y-4
y=-2+2x
y=2x+2
Step-by-step explanation:
lets start with x
x-2y=-4
x=-4+2y
x=2y-4
now y
x-2y=-4
2y=-4+x
y=-2+2x
x=2y-4
2y=x+4
y=2x+2

Valentina and her parents are on a long drive to Monterey Bay to go kayaking. She passes the time by counting how many different colors of cars she sees. The table below shows the results.
Color of car Number of cars
black 4
red 7
silver 12
white 14
brown 5
blue 3
Based on the data, what is the probability that the next car seen is brown?
Write your answer as a fraction or whole number.
Based on the data provided, Valentina saw a total of 4 + 7 + 12 + 14 + 5 + 3 = 45 cars. Out of these cars, 5 were brown. Therefore, the probability that the next car seen is brown is 5/45 which can be simplified to 1/9.
