Answer:

137

Step-by-step explanation:

175+115+145+115+135= 685

685÷5= 137

To put that into words you add up all the numbers and divide the sum by how many numbers there are.

I need help don’t understand

nadya68 [22]

If f(x)=x+1 and then x became 2, you would have the function f(x)=3. So basically for that function you would be going up three over 1. That function is already g(x)=4x. If X became 2, you would have g(x)=8x. The rate of up 8 and then over one. Because of that, g(x) would be higher

What is the value of x in the equation -6/7= -×/84?

pantera1 [17]

-6/7 = -x/84

84/7 = 12

12(-6) = -72

x = -72

So, -6/7 = -72/84 because -72/84 simplifies to -6/7

What percent of 29.5 is 10.03

Alexxandr [17]

So if we take 29.5 to be the 100%, what is 10.03 in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
29.5&100\\
10.03&p
\end{array}\implies \cfrac{29.5}{10.03}=\cfrac{100}{p}\implies p=\cfrac{10.03\cdot 100}{29.5}$

For what power of q is its value 1?

DedPeter [7]

Answer:

0, for q ≠ 0 and q ≠ 1

Step-by-step explanation:

Assuming q ≠ 0, you want to find the value of x such that ...

q^x = 1

This is solved using logarithms.

x·log(q) = log(1) = 0

The zero product rule tells us this will have two solutions:

x = 0

log(q) = 0 ⇒ q = 1

If q is not 0 or 1, then its value is 1 when raised to the 0 power. If q is 1, then its value will be 1 when raised to <em>any</em> power.

_____

<em>Additional comment</em>

The applicable rule of logarithms is ...

log(a^b) = b·log(a)

Find the missing dimension of each triangle described Height: 7 in., area: 21 in2

leonid [27]

The basic dimensions of any triangle are its area, base, and height.
They're related by the area equation; the area is half of the base times the height, or:
$A=\frac{1}{2} b h$
We know the area and the height, so the missing dimension has to be the base. Let's set up an equation by substituting the values the problem gives into the area equation.
$21=\frac{1}{2} \cdot b \cdot 7$
Can you solve this equation for $b$ ?
