What is 7% of $1.50​

Mathematics

Answer:

0.105

0.11 if you are expected to round to nearest cent.

Step-by-step explanation:

"of" should be thought of as times.

So you are doing:

7\% \cdot 1.50

7% is the same as .07; you could just replace percent with times 1/100 if you don't know. Like this 7%=7*1/100=7/100=.07.

.07 \cdot 1.50

When putting this into the calculator you get 0.105.

Answer:

<h2>7% of %1.50 is equal to $0.105 ≈ $0.11</h2>

Step-by-step explanation:

METHOD 1:

\begin{array}{ccc}100\%&-&\$1.50\\7\%&-&\$x\end{array}\qquad\text{cross multiply}\\\\100x=(7)(1.50)\\\\100x=10.50\qquad\text{divide both sides by 100}\\\\\dfrac{100x}{100}={\dfrac{10.5}{100}\\\\x=0.105

METHOD 2:

p\%=\dfrac{p}{100}\to7\%=\dfrac{7}{100}=0.07\\\\7\%\ of\ \$1.50\ is\ equal\ to\ 0.07\ of\ \$1.50:\\\\0.07\cdot\$1.50=\$0.105

If f(x)=2x+7 and g(x)=11x-4, find (f+g)x.
klemol [59]

Answer:

(f+g)(x) = 13x + 3

Step-by-step explanation:

Rewrite  f(x)=2x+7 and g(x)=11x-4 in columns, as follows:

f(x)=2x+7

+g(x)=11x-4

----------------

Now add each column separately.

f(x)+g(x) = (f+g)(x) ("the sum of functions f and g")

2x + 11x = 13x, and, finally, 7-4 = 3.


Therefore,

 f(x)=2x+7

+g(x)=11x-4

----------------

(f+g)(x) = 13x + 3

In 5 years it grew 6 mill (181-175=6). Formula: 6(20/5)+181=X. multiply 6 by 4 (the number of five years in twenty years): 24. 24+181=205 million :)

Can anyone pls answer this! it's really urgent! ​
stich3 [128]

Answer:

The answer is C

Step-by-step explanation:

You need to find a common denominator and in this case its 20. SO you change 3/4ths to 15/20 and 4/5ths to 16/20ths and 19/20 stays the same. Then you cancel out the 20 because its all the same number (I think) and you have your answer.

A custom rectangular tabletop has a length that is twice it’s width, and the tabletop measures 76 inches on its diagonal. What a
Sunny_sXe [5.5K]

Answer:

<em>The dimensions of the tabletop: Length= 67.976... inches and Width= 33.988... inches and the perimeter will be 203.929... inches.</em>

Step-by-step explanation:

Suppose, the width of the rectangular tabletop is x inch.

As the tabletop has a length that is twice it’s width, so the length will be:  2x inch.

The tabletop measures 76 inches on its diagonal.

<u>Formula for length of diagonal of rectangle</u>:  d=\sqrt{l^2+w^2}

So, the equation will be..........

76=\sqrt{(2x)^2+ x^2}\\ \\ 76=\sqrt{4x^2+x^2} \\ \\ 76=\sqrt{5x^2} \\ \\ 5x^2= 76^2= 5776\\ \\ x^2= \frac{5776}{5}=1155.2 \\ \\ x= \sqrt{1155.2} =33.988...

Thus, the width of the tabletop is 33.988... inches and the length will be:  (2×33.988...) = 67.976... inches.

The perimeter will be:  2(33.988...+ 67.976...) inches = 203.929... inches.
