Answer:
x = 7.5 cm
Step-by-step explanation:
ΔBCA ~ ΔECD ⇒ the corresponding sides are proportional.
[tex]\frac{AC}{DC}[/tex] = [tex]\frac{AB}{DE}[/tex]
AC = 4 + 6 = 10 cm
[tex]\frac{10}{6}[/tex] = [tex]\frac{x+5}{x}[/tex] ⇔ 10x = 6(x + 5) ⇒ x = 7.5 cm

What's the answer?
Answers
Answer:
h = 12
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
0.75h + 3 = 12
Step 2: Solve for h
Subtract 3 on both sides: 0.75h = 9Divide 0.75 on both sides: h = 12Step 3: Check
Plug in h into the original equation to verify it's a solution.
Substitute in h: 0.75(12) + 3 = 12Multiply: 9 + 3 = 12Add: 12 = 12Here we see that 12 does indeed equal 12.
∴ h = 12 is a solution of the equation.
Answer:
h = 12
Step-by-step explanation:
Given
0.75h + 3 = 12 ( subtract 3 from both sides )
0.75h = 9 ( isolate h by dividing both sides by 0.75 )
h = 12

Pocahontas opens a savings account with $640 dollars that earns 3.9% interest per year not compounded. How much money to the nearest penny will Pocahontas have in 8 years
Answers
Given:
Principal value = $640
Rate of interest = 3.9% not compounded
Number of years = 8
To find:
The amount after 8 years.
Solution:
It is given that the interest is not compounded. It means, we need to find simple interest.
Formula for simple interest:
[tex]I=P\times r\times t[/tex]
where, P is principal, r is rate of interest and t is time in years.
Put P=640, r=0.039 and t=8.
[tex]I=640\times 0.039\times 8[/tex]
[tex]I=199.68[/tex]
So, the interest is $199.68.
Now, amount after 8 years is
[tex]A=P+I[/tex]
where, P is principal and I is interest.
[tex]A=640+199.68[/tex]
[tex]A=839.68[/tex]
Therefore, the amount after 8 years is $839.68.

A circle divided into 4 parts. 2 parts are shaded.

One-fourth
Two-fourths
Three-fourths
Four-fourths
Answers
A circle is divided into 4 parts out of which 2 parts are shaded. The diagram is attached for a better understanding. The fraction equivalent to 'Half' is 'Two-fourths'.
A fraction is part of the whole. It consists of two parts, that are:
1. Numerator: The number at the top of a fraction is called Numerator.
2. Denominator: The number at the bottom of a fraction is called Denominator.
The 'Half' is written in the number system as [tex]\dfrac{1}{2}[/tex].
Let's multiply the numerator and denominator by 2,
[tex]\dfrac{1}{2}= \dfrac{1 \times 2}{2 \times 2} = \dfrac{2}{4}[/tex]
Hence, the factor 'Two-fourths' is equivalent to 'Half'.

When you are dealing with a problem like this how do you solve it to make sure that the exponent is positive?
14 to the -4 power times 14 to the 7 power. I know that we will keep the base because they are the same but do I add or subtract the exponents?
Answers
Answer:
All you need to remember is the rules
Step-by-step explanation:
Let us remember
a to the m power x a to the nth power is = a to the m+n power. (add the exponents)
And
a to the m power ÷ a to the nth power is = a to the m-n power. (subtract the exponents) So
14 to the -4 power x 14 to the 7 power= 14 to the -4+7 which is equal to 14 to the 3rd power

Processing fee = 42 dollars; Daily fee = 102 dollars
Max number of days you can rent house = 11 days
========================================================
Explanation:
Part 1
Let
x = number of days
y = total cost in dollars
Note how each time x goes up by 2, y goes up by 204 (since 450-246 = 204). This consistent pattern directly tells us we have a linear equation going on. The next section goes into more detail.
--------------------
Part 2
The daily fee is directly tied to the pattern mentioned earlier. We have the cost going up by $204 each time 2 days go by. So the daily fee is 204/2 = 102 dollars per day.
You could also use the slope formula with say the first two columns of the table
m = (y2-y1)/(x2-x1)
m = (450-246)/(4-2)
m = 204/2
m = 102
This confirms the daily fee is $102.
You can use any two columns of the table that you want to get the slope. It doesn't have to be the first two columns.
Now use (x,y) = (2,246) along with m = 102 to find the y intercept. Like before you can use any column you want to form the (x,y) value.
y = mx+b
246 = 102*2+b
246 = 204+b
246-204 = b
42 = b
b = 42
The equation is y = 102x+42. The initial processing fee is $42. If you stayed at the house for x = 0 days, you still have to pay the fee y = 42.
--------------------
Part 3.
Plug in y = 1200 and solve for x
y = 102x+42
1200 = 102x+42
1200-42 = 102x
1158 = 102x
102x = 1158
x = 1158/102
x = 11.3529411764706
x = 11
We round down to the nearest whole number. This way we clear the hurdle.
Note that if x = 11, then,
y = 102x+42
y = 102*11+42
y = 1164
which is under the $1200 budget
In contrast, plugging in x = 12 leads to
y = 102x+42
y = 102*12+42
y = 1266
which is over the 1200 dollar budget. This shows that x = 11 is the max number of days you can rent the house.

Please help me, This is the only question I don’t understand pleas help me I would really appreciate it thank you!
Answers
Answer:
C
Step-by-step explanation:
A proportional equation is in the form:
[tex]\displaystyle y=kx[/tex]
Where y is the dependent variable, x is the independent variable, and k is the constant of proportionality.
An important aspect of a proportional equation is that it passes through the origin. That is, it has no y-intercept (or a constant value).
From our choices, the only choices that don’t have y-intercepts are C and D.
However, D is not a linear function.
Therefore, our answer is C.
And our constant of proportionality is 1/2.

Explanation:
If you just look at it like a straight line then you know it equals 180° but since it’s cut into pieces we have to figure out the others first.
So on the triangle on the bottom it’s 50 and 50 so add those and subtract from 180 to find out what the third angle in the triangle is.
50+50=100
180-100= 80°
Now the angle to the right of the 60° is going to be 80 because they’re corresponding.
So, if the one side of the split line is 80 then the other must be 100°.
