Consider the diagram. BC is parallel to DE. Find the length of BC.

Answer:

A

Step-by-step explanation:

If you use process of elimination, it is the only one that makes since in the situation.

Answer:

Change two-thirds to a decimal and then multiply the decimal and your number. To convert 2/3 to decimal, divide the numerator by the denominator: 2 / 3 = 0.66666 ... 7, which you can round to 0.67. For example, to find 2/3 of 21: 0.67 * 21 = 14.07.

Step-by-step explanation:

The number of total students is 18+12+10=40

So

1) 18:40 but simplified it will be 9:20

2) 10:40 but simplified it will be 1:4

3) 30:40 but simplified it will be 3:4

4) 30:10 but simplified it will be 3

5) 18:22 but simplified it will be 9:11

N.B simplified means dividing them by their common multiple. so the final answer for each is the number after it is simplified

Answer:

Exact form: y=40/3

Decimal form: y=13.3

Mixed number form:

[tex]13 \frac{1}{3} [/tex]

Hope this helps!

y = -8/9

1)
The first thing you have to do is multiply both sides (opposite of division because it was divided by 5) by 5 to get y by itself on the right side. Your equation will then be 15y-40/60=y.

2)
Then you want to get rid of the divided by 60 on the left side, to do this you have to do the opposite of division which is multiplication. So multiply both sides by 60. Your equation will then be 15y-40=60y.

3)

To combine like terms, you have to bring y to one side, ill just bring the 15y over to the right, we do this by subtracting 15y to both sides (since its positive (+)15y we do the opposite which is subtraction (-). After we do this the equation will be -40=45y.

4)

Now what we are trying to do is get y by itself, so we do the opposite of what it is which is division (we do division because its multiplication 45y is 45 (times)x y). We divide 45 by both sides and our y is by itself! the new equation is -40/45=y which is our answer!

5)

But we can still simplify! Once the answer is simplified the final answer should be -8/9=y!

Answer:

x = 1

Step-by-step explanation:

a^2 + b^2 = c^2

The hypotenuse (c) and a side length is already given, so:

x^2 + 12 = 13

x^2 = 1

Square root of 1 = 1

So, x = 1

You can check it by 1+12=13

Answer:

b. Hannah

Step-by-step explanation:

Because, she deviates by 5, whereas Isabella only deviates by 2. Therefore, Hannah is relatively younger according the mean age of the degree level.

Answer:

A mathematical sentence is the analogue of an English sentence; it is a correct arrangement of mathematical symbols that states a complete thought. ... For example, the sentence '1+2=3 1 + 2 = 3 ' is true. The sentence '1+2=4 1 + 2 = 4 ' is false.

Danielle spent three times as much on transportation as she did on lunch, so we can call this 3x.

She spent $4 less than on books than she did on transportation -> 3x - 4

So, she spent x + 3x + 3x - 4 (simplified as 7x - 4).

Danielle had $59 to spend last week -> 7x - 4 = 59
Solve for x : (59+4)/7 = 9

So, she can spend at max $9 on lunch


Recheck : 9 + 27 + 27 - 4 = 63 - 4 = 59.

Answer:

Total - 8.4 kilos

Pears; 2/5

Apples; Unknown

The rest of the 2/5 of pears is 3/5 apples.

3/5(apples) x 8.4(kilos)

0.6 x 8.4 = 5.04 or 5 4/100 which simplifies to 1/25

[tex]3 * (x - 5)\\3 - 5 = 2\\2 * 3 = 6[/tex]

Therefore, x is 3.

Answer:

3821.9 [cm³].

Step-by-step explanation:

1) the required volume can be calculated as:

V=V(prism)-V(cylinder);

2) V(prism)=32*12*11=4224 [cm³];

3) V(cylinder)=π*r²*32=3.1415*4*32≈402.1 [cm³];

4) finally, V=4224-402.1=3821.9 [cm³].

For more info see the picture in the attachment.

Answer:

3,822.08 cm2

Step-by-step explanation:

You would start off by finding the volume of the who post which is 4,224. You then would find the volume of the hole cut out which is 401.92. Then you would subtract 401.92 from 4,224 giving you 3,822.08.

Hope this helps!

Answer:

Where's the model?

Hai there!

First, let's use the KCF technique (my old math teacher taught me this!)

Keep the first fraction the same, in this case, 1/2

Change the sign from division to multiplication

Flip the second fraction, or 3/8, to get it's reciprocal, or 8/3.

The new equation should look like this:

1/2 * 8/3

Now multiply straight across like you normally would, like so:

1 * 8 = 8

2 * 3 = 6

No answer!
