Let number of science problems=x
no. of math, problems=x+10
x+x+10=42
2x=42-10=32
x=32/2=16
hence number of science problems=16
no.of math problems=16+10=26

First do 42-10
which is 32
then divide 32 by 2 and get 16
so your answer is 16 math problems and 26 science problems

Give the answer <br> the areaaaaaa
GalinKa [24]

Answer:

16

Step-by-step explanation:

The figure shown is a trapezoid

Area of a trapezoid = 1/2(bottom base length + top base length) × height

Bottom base length = 7 units

Top base length = 1 unit

Height = 4 units

So area = 1/2 ( 7 + 1 ) × 4

==> add 7 and 1

Area = 1/2 (8) × 4

==> multiply 1/2 and 8

Area = 4 × 4

==> multiply 4 and 4

Area = 16

14,345,678 (nearest hundred thousand) * what’s is the answers
Readme [11.4K]

Answer:

14,300,000

Step-by-step explanation:

Starting off with 14 million, you haven't reached the 100 thousands or below yet where you should start. The next digit, 3, is in the 100 thousands place and the digit next to it is four. When you're rounding, if the digit is greater than five, then you round up. (example: if the number you're rounding is 67, seven is greater than five so you would round it to 70.) If the digit you are rounding is smaller than 5 then you would round down. (Example: if the number you're rounding is 34, then you would round down because four is smaller than five or higher.) Since in your problem, you have 345,678, (we've already discussed the 14 million part in the beginning) 4 is smaller than 5 or higher so it would round 14,345,678 to 14,300,678. However, since we've already rounded the part we meant to do, every digit after would turn to 0. The final result would be 14,300,000.

Suppose the coordinate of a is 0, ar = 5, and at =7. What are the possible coordinates of the midpoint of rt ?
77julia77 [94]

Here 'a' corresponds to 0.

Now there are two possibilities for 'r' & 't'

Case 1.

They are on the same side to the right of 'a'

In that case 'r'  corresponds to 5 & 't' corresponds to 7.

The midpoint of 'r' and 't' shall be \frac{5+7}{2} =6

Case 2.

Both are on the left of 'a'.

In that case 'r' corresponds to -5 & 't' corresponds to -7

The midpoint shall be \frac{-7-5}{2} =-6

Case 3.

'r' in on the right of 'a' and 't' is on the left of 'a'

So 'r' corresponds to 5 and 't' corresponds to -7

The midpoint shall be \frac{-7+5}{2}=-1

Case 4.

'r' is on the left of 'a' & 't' is on the right of 'a'.

'r' corresponds to -5 & 't' corresponds to 7

The midpoint shall be \frac{-5+7}{2}=1

The possible coordinates of the midpoints of rt are 6, -6, 1, -1.
