Answer:
$185
Step-by-step explanation:
First, find the amount that she deposited from her uncle's shop:
250(1/2)
= 125
Then, find how much she deposited from baby sitting:
80(3/4)
= 60
Add these 2 values up:
125 + 60
= 185
So, she deposited $185 that month
Identify the vertex of each.
2) y = 2x² + 24x + 75
There would be no x intercepts (I think)
And the y intercept would be (0,7)
So the vertex would be (-6,3)

What is the distance between (3, 5.25) and (3, –8.75)?
Answer:
The answer is
14 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(3, 5.25) and (3, –8.75)
The distance between them is
[tex]d = \sqrt{ ({3 - 3})^{2} + ({5.25 + 8.75})^{2} } \\ = \sqrt{ {0}^{2} + {14}^{2} } \\ = \sqrt{196} \: \: \: \: \: \: \: \: \: \: \\ = 14 \: \: \: \: \: \: [/tex]

Tina's Beauty Salon charges $10 per haircut. If the salon has 52 visitors seeking haircuts per day, estimate
how much Tina would make in 5 days by rounding the number of visitors to the nearest ten.
Group of answer choices
$50
$2500
$500
$250
Answer:
2500
Step-by-step explanation:
$10 times 52 is $520 a day so multiply 520 times 5 and you get $2600 so round that and it is $2500
Find the volume of the solid under the plane 3x+2y−z=0 and above the region enclosed by the parabolas y=x^2 and x=y^2.
The region in the x-y plane is the set of points
[tex]R=\{(x,y)\mid0\le x\le 1,x^2\le y\le\sqrt x\}[/tex]
The height of the solid falls between the x-y plane (for which z = 0) and the equation of the plane, z = 3x + 2y.
So the volume is
[tex]\displaystyle\int_0^1\int_{x^2}^{\sqrt x}\int_0^{3x+2y}\mathrm dz\,\mathrm dy\,\mathrm dx[/tex]
[tex]=\displaystyle\int_0^1\int_{x^2}^{\sqrt x}(3x+2y)\mathrm dy\,\mathrm dx[/tex]
[tex]=\displaystyle\int_0^1(3x^{3/2}+x-3x^3-x^4)\,\mathrm dx[/tex]
[tex]=\displaystyle\frac65+\frac12-\frac34-\frac15=\boxed{\dfrac34}[/tex]

Paul has $20,000 to invest. His intent is to earn 11% interest on his investment. He can invest part of his money at 8% interest and part at 12% interest. How much does Paul need to invest in each option to make get a total 11% return on his $20,000?
Answer:
In the 8% option , $5,000 should be invested
In the 12% option, $15,000 should be invested
Step-by-step explanation:
Let’s start with the total return.
Since the total return expected is 11%, the amount expected to be returned will be;
11/100 * 20,000 = $2,200
Now, let the amount invested at 8% interest be $x while the amount invested at 12% interest be $y
Mathematically;
x + y = 20,000 ••••••(i)
Now let’s work with the interest part;
On the 8% part, amount of interest expected is 8/100 * x
on the 12% part, amount of interest expected is 12/100 * x
8% of $x + 12% of $y = 2,200
Writing this fully mathematically, we have;
(8/100 * x) + (12/100 * y) = 2,200
8x/100 + 12y/100 = 2,200
Multiply through by 100
8x + 12y = 220,000 ••••••(ii)
Now we have two equations to solve simultaneously;
x + y = 20,000
8x + 12y = 220,000
From i, x = 20,000-y
Substitute this into ii
8(20,000-y) + 12y = 220,000
160,000-8y + 12y = 220,000
4y = 220,000 - 160,000
4y = 60,000
y = 60,000/4
y = $15,000
x = 20,000 -y
x = 20,000 - 15,000
x = $5,000

The number 25w^9x^6 - 4 is not factorable.
6) Order the fractions and decimals from least to greatest 0.75, 1/2, 04, 1/5
Answer:
Order from least to greatest: 1/5, 0.75, 1/2, 04.
Explanation:
1/5 is the least because 0.75 is equivalent to 1/4 and 1/2 is greater than both of those. 04 is a whole number because the 0 doesn't matter if there's no decimal point, which there isn't. So take away the 0 and you get the whole number 4! Hope this helped :)

A patient's temperature was recorded at 9 a.m., 11 a.m., 4 p.m. and 6 p.m. The first, second, and fourth readings were 112° F, 68° F and 85° F, respectively. If the average of the four readings was 84.75° F,
what was the third reading?
Answer:
74°F
Step-by-step explanation:
In order to find the average of a certain amount of numbers, you add those numbers together and divide by how many numbers there are. In this case, you would reverse that method to find the last number. We know that there were four readings, and we have three of them and the average. Multiply the average (84.75) by the number of readings (4), and you get the sum of all the readings (339). Then you subtract each of the readings that you already know to isolate the last reading. 339 - 112 (first reading) = 227, 227 - 68 (second reading) = 159, and 159 - 85 (fourth reading) = 74. Therefore, the third reading must be 74.

On John's flight to New York City, the plane flies 740 miles with a tailwind, which increases its speed. On the flight back
home, the plane travels against the same wind, which decreases its speed. Assume the airplane cruises at a speed of

Find the equation of the line that passes through the point (5, -4) and is perpendicular to the line y=1/4x - 2 .
Answer:
The equation of the line is:
[tex]y = -4\,x +16[/tex]
Step-by-step explanation:
A line perpendicular to the given one is going to have a slope equal to the opposite of the reciprocal of 1/4. That is the slope of the new line will be "-4".
Now we write the point-slope form for a line using the info provided of slope -4 and point (5, -4):
[tex]y-y_0=m\,(x-x_0)\\y - (-4) = -4 \,(x-5)\\y+4 = -4\,x +20\\y = -4\,x +16[/tex]
Answer:
y = -4x + 16
Step-by-step explanation:
For questions like this, I would first find the slope of the line that we are trying to find the equation for. To do this, I would use the line y = 1/4x - 2 and find the slope of a line that would be perpendicular to it. Taking the negative reciprocal of the slope of y = 1/4x - 2 will do just that.
By looking at the equation y = 1/4x - 2, we can see that the slope of the line is 1/4. The negative reciprocal of 1/4 would be -4, which would be the slope of the line whose equation we are trying to find.
Since we have a point on the line, and we now have the slope of the line, we can now make an equation for the line in point-slope form:
y + 4 = -4(x - 5)
Now while this is an equation for the line, lets try to get it into slope-intercept form:
y + 4 = -4(x - 5)
Distribute the -4 on the right side of the equation.
y + 4 = -4x + 20
Subtract 4 from both sides.
y = -4x + 16
And now we have the equation of the line in slope-intercept form.

Answer:
1. Statisticians and operations research analysts.
2. 167,582.3 persons.
3. 40%.
4. Pharmacist
Step-by-step explanation:
1. According to data from the U.S. Bureau of Labor Statistics, Statisticians and Operations Research analysts are among the fastest-growing occupations in terms of their percent growth, having high projected growth rates of 33.8 percent and 30.2 percent.
2. People who are expected to work as Mathematicians by 2026 are projected to grow up to 27.9 percent (167,582.3 persons).
3. About 40% of the fastest-growing careers are in the health & human services industry. This is the case because as the human population continues to increase, the need for healthcare providers will increase rapidly.
4. Considering the lower projection of 22% for this career, it gives better prospects for getting employment due to the limited supply of Pharmacists.
