50% of what number is 307
Answer:
614
Step-by-step explanation:
Let the number be x.
50% × x = 307
0.5x = 307
x = 307/0.5
x = 614
50% of 614 is 307.
Answer:
614
Step-by-step explanation:
50% means half. So,
x ÷ 2 = 307
x = 307 × 2
x = 614

Its B. This is the answer because you have to cancel out the square root in the denominator. So if you multiply the square root of 11 times itself then it would become the square root of 121, which equals 11 and completely cancels out.
Answer:
Answer is option b
Step-by-step explanation:
To rationalise the denominator we should multiply that expression by second option.

Determine the value of k that would make these two functions inverses.
Answer: K = 6
Step-by-step explanation:
If you find the inverse of the inverse function, it will return back to initial function.
The inverse of r^-1 (x) will give r(x).
To find the inverse of r^-1(x), let it be equal to y. Interchange y and x for each other and make y the subject of formula. That is,
Y = 2x^2 - 14
Interchange y for x
X = 2y^2 - 14
2y^2 = x + 14
Y^2 = x/2 + 14/2
Square both side
Y = sqrt ( x/2 + 7 )
It is only when K = 6, that will can get the value above.

If we draw a picture, it would help a lot. Once we visualize the triangle, we can see that we have sin∅ = 2/3. So, plugging into your calc,
sin∅ = 2/3
∅ = sin^-1(2/3)

Eleven plus forty-one is divided by a number. If the result is 13, what's the number?
Answer:
4
Step-by-step explanation:
Let the number be x.
(11+41)/x = 13
52/x = 13
13x = 52
x = 52/13
x = 4
The number, if Eleven plus forty-one is divided by a number, and the result is 13, is 4.
What is division?It is the basic arithmetic operation, in which you are separating the number into some parts.
Given:
Eleven plus forty-one is divided by a number, and the result is 13,
Assume the number is x,
Write the equation as shown below,
11 + 41 / x = 13
52 / x = 13
x = 52 / 13

What is the slope intercept equation of a line that has a slope of -2 and a y-intercept of (0, 3)
Answer:
y = -2 x +3
Step-by-step explanation:
If the slope must be "-2", then the slope intercept form of the line should look like;
y = m x + b
with the slope "m" = -2
That is:
y = -2 x + b
Now the constant "b" can be found using the info on the value of the y-intercept which is (0, 3), so when x = 0, the value of the y-coordinate must be 3. By imposing this condition into the equation, we can find the value of "b":
3 = -2 (0) + b
3 = b
Then the equation becomes:
y = -2 x +3
Jose decided on purchasing a $145,000 home. At closing he brought a check
for $4645. The closing costs were as follows:
Title Fee
$545
Processing Fee $1975
Appraisal
$675
Based on this information, how many points did Jose purchase?
Answer: 1
Step-by-step explanation:
Given the following:
Title fee = $545
Processing fee = $1975
Appraisal = $675
Total : $(545 + 1975 + 675) = $3195
Amount of check brought = $4645
Which is in excess of the total:
$(4645 - 3195) = $1450
Cost of home = $145,000
The percentage of the excess paid with respect to the cost of home will give the number of points Jose purchased. They are used to lower the monthly cost of a mortgage.
(Excess amount / cost of home) × 100%
(1450 / 145000) × 100
0.01 × 100% = 1%
The number of points 1 percentage point.

Answer:
X = 75
Step-by-step explanation:
Angle F and angle X are corresponding angles so they are congruent (equal)
Angle F and 105 form a straight line so they are supplementary angles, which means they add to 180
F+ 105 = 180
F = 180-105
F = 75

What is another way to make 4.65?
Answer:
0.465 ×10
Step-by-step explanation:
Step-by-step explanation:
When you ask, "What is 4.65 as a decimal?", we assume you want to know what 4.65 percent is as a decimal. In other words, 4.65 percent converted to decimal.
First, we will tell you why it is useful to know 4.65 as a decimal.
Normally, to calculate 4.65 percent, you would multiply a number by 4.65 percent and then you would take the product of that and divide it by 100 to get the answer.
Instead, you can simply multiply a number by 4.65 as a decimal to get the answer.
4.65 percent means 4.65 per hundred. Therefore, to get 4.65 as a decimal, all you have to do is divide 4.65 by 100 like so:
4.65 ÷ 100 = 0.0465
Shortcut: When you divide anything by 100, just move the decimal point two places to the left.

Sarah currently earns $18.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 20% raise. How much will she earn each hour after the raise?
Step-by-step explanation:
18 = 20/100 18x100=1800÷20=9020x?=1800 20x90=1800
Sarah will earn $ 21.60 following the percentage increase
What Does Percent Mean?A ratio or figure stated as a fraction of 100 is called a percentage. The percent marker is frequently used to indicate it,%
The approximation error in a data value is the distinction between a precise value and one that is close to it. This error may be referred to as either an absolute error or a relative error.
The difference between the measured value and the true value, expressed as a percentage of the true value, is known as a percentage change.
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Let the amount Sarah will get following the percentage increase be A given the available facts.
Right now, Sarah's starting salary is $ 18.00.
20% is the proportion that hourly work will rise.
Hence, the amount of increased hourly work equals 20% of Sarah's starting salary.
Simplifying results in
The increase in hourly pay is (20/100) times 18 ($3.60)
Now, the amount Sarah will get following the % increase is A = the starting sum Sarah earns + the increase in hourly pay.
And Sarah will earn A = $ 18.00 + $ 3.60 = $ 21.60 after the percentage increase.
Hence, an increase of $ 21.60 is required for hourly employment.

ASAP!! A triangle has an area of 72 square feet, and a base measuring 6 feet. If a square was drawn with a side measuring the same as the height of the triangle, what would be the perimeter of that square?
Answer:
Perimeter of square = 96 ft
Step-by-step explanation:
Area of triangle = 72 ft²
Base of triangle = 6 ft
We know that the formula for Area of triangle is given as:
Area = (1/2) · Base · Height
Substitute the values:
72 = (1/2) · 6 · Height
72 = 3 · Height
Height = 72/3
Height = 24 ft
As the Height of triangle is equals to Side of square:
Side of square = 24 ft
Perimeter of square = 4 · (side of square)
Perimeter of square = 4 · (24)
Perimeter of square = 96 ft
