x = [?]
Answer:
x = 3
Step-by-step explanation:
Δ BDE and Δ BAC are similar triangles, thus the ratio of corresponding sides are equal, that is
[tex]\frac{BD}{BA}[/tex] = [tex]\frac{BE}{BC}[/tex], substitute values
[tex]\frac{x+5}{3x+5}[/tex] = [tex]\frac{4}{7}[/tex] ( cross- multiply )
4(3x + 5) = 7(x + 5) ← distribute parenthesis on both sides )
12x + 20 = 7x + 35 ( subtract 7x from both sides )
5x + 20 = 35 ( subtract 20 from both sides )
5x = 15 ( divide both sides by 5 )
x = 3
Find the area of a circle with a diameter of 8 in. Rounded to the nearest tenth. Use 3.14 for π.
210 in
210 in^2
50.2 in
50.2 in^2
Answer:
50.2 in^2
Step-by-step explanation:
Using the Formula
A=πr2
d=2r
Solving for A
A= 1/4 π d^2 = 1/4*π*8^2 = 50.26548
=50.2in^2

John says the transformation rule (x, y) = (x + 4, y + 7)
can be used to describe the slide of the pre-image (4,5)
to the image (0, -2). What was his error?
Answer:
The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5) into the rule. You get (4, 5) → (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image. Instead the rule was applied to the image. This is the source of the error.

What is the value of x in the figure?
Answer:
29
Step-by-step explanation:
Since we know that the x-axis is 180 degrees and the square looking symbol represents that it is 90 degrees, we know that the other side has to also equal 90 degrees since 180-90=90.
To find the x, we need to subtract 90 from 61, which would give us 90-61 = 29.

List all the common multiples of 9,12 and 15 between 1 and 100
Answer:
There is no common multiple of 9, 12 and 15 between 1 and 100
Step-by-step explanation:
The common multiples of 9, 12 and 15 between 1 and 100
Fist the lowest common multiple
9 = 3 * 3
12 = 3 * 4
15 = 3 * 5
Hence the lowest common multiple
= 3 * 3 * 4 * 5
= 180
Since the lowest common multiple of 9, 12 and 15 is greater than 100, it means that there is no common multiple of these numbers between 1 and 100
How do I show my work if these are parallel or not?
You can determine if things are parallel if the lines will eventually meet or not. M and N are one line while P and Q are also a line. Therefore, we can say P is one line while M is also one line. The answer would be is that they are parallel, the two lines will not crash with one another. To show your work as if they are parallel, you can continue the lines down and write a note saying they won't collide or you just say they won't collide and are parallel lines.
You finally get an allowance! You put $2.00 away in January, $4.00 away in February, $8.00 away in March, $16.00 away in April and followed this savings pattern through to December. How much money do you have in 12 months? *
Answer:
$8190
Step-by-step explanation:
So we know that were putting away $2 each month from our allowance.
Jan-$2
Feb-$4
March-$8
April-$16
Ok so we already put away 4 months of our allowance from 12. So we need 8 more months to count how much.
So lets add: 2 + 4 + 8 + 16=30
Now we need to figure out how much in May and so on.
May- 16x2=32
June-32x2=64
July-64x2=128
August-128 x 2=256
September-256 x 2=512
October-512 x 2=1024
November-1024 x 2=2048
December-2048 x 2=4096
In total to add:
2 + 4 + 8 + 16 + 32 +64 + 128 + 256 + 512 + 1024 + 2048 + 4096 = 8190
Hope this helps :)
