Answer:
$86.25
Step-by-step explanation:
You need to calculate 15% of $75, and then add it to $75.
To find a percent of a number, change the percent to a decimal and multiply by the number. To change a percent to a decimal, divide the percent by 100, which the same as moving the decimal point of the percent two places left.
For example, 15% = 15/100 = 0.15 (by dividing 15 by 100).
15% = 0.15 (by moving the decimal point of 15 two places to the left).
Now back to the problem. First, we find 15% of $75.
15% of $75 =
= 15% * $75
= 0.15 * $75
= $11.25
The tip of 15% of $75 was $11.25.
The total amount spent is the bill total, $75, plus the $11.25 tip.
Total spent = $75 + $11.25 = $86.25

what is the domain function y=^4sqrtx-1
Answer:
Domain of y=[tex]\sqrt[4]{x-1}[/tex]: is x>=1
Interval notation: [1,∞)
Step-by-step explanation:
We have y=[tex]\sqrt[4]{x-1}[/tex]
1) The domain of a function is the set of x values for which the function is real and defined.
2) So, x-1 should be positive means x-1>=0, because fourth root of any negative value would be a complex number and not a real number.
3) Now we solve the inequality x-1>=0
4) Adding 1 to both sides of the inequality we get,
x-1+1 > = 0+1
5) Cancel out -1 and +1 from the left side
6) We get x>=1
It concludes that for the domain of the given function, the x value must be greater than or equal to 1
20,000 has been placed in a bank account that earns 5.7% interest. How much money will be in the account if it is compounded semi annually for 3 years
Answer:
$25 821.69
Step-by-step explanation:
The formula for the future value (FV) of an investment is
FV =PV(1 + r/n)^nt
FV = 20 000(1 + 0.087/2)^(2×3)
FV = 20 000(1 + 0.0435)⁶
FV = 20 000(1.0435)⁶
FV = 20 000 × 1.291 0847
FV = $25 821.69

Mr.King is creating an area for his flower garden in his yard. The length across the garden is 8 feet. If Mr.King splits his garden where 50% of the space is for tulips and the other 50% is for daisies,how much space will be filled with daisies? (Need photo of step by step if possible)
Answer:
2
Step-by-step explanation:
Final answer:
Assuming a square garden with each side being 8 feet, 50% of the space allocated to daisies would be 32 square feet.
Explanation:
Mr. King is dividing his garden evenly for tulips and daisies, meaning each flower type will occupy 50% of the garden's area. The length of the garden is given as 8 feet, but the width is not mentioned. To determine the actual area for daisies, we need both dimensions of the garden. However, if we assume that the width is also provided or the garden is square (8 feet by 8 feet), then the total area of the garden is 64 square feet (8 feet * 8 feet).
Now, to find the space filled with daisies, we calculate 50% of the total area:
0.50 * 64 square feet = 32 square feet.
Therefore, if the garden is a square and the other dimension equals the given length, the space filled with daisies will be 32 square feet.

The distance between the cities Chicago and Toronto is 540 miles. A motorcycle's speed is 48 mph. For a car it takes 2.25 hours less to cover same distance than for the motorcycle. How long does it take them to meet, if they start moving towards each other simultaneously?
Answer:
Motorcycle will complete the 540 mile trip in 11.25 hr.
The car will complete it 2.25 hours less, or 9 hours.
The speed of the car therefore is 540/9 = 60 mph.
60t + 48t = 540
108t = 540
t = 5
So they will meet in 5 hours, after which time the motorcycle will have traveled 48*5 = 240 miles
and the car will have traveled 60*5 = 300 miles.

the lopez family spent 22.10 on drinks for their annual picnic the cost of each drink was $0.85 if each person received 1 drink how many people attended the picnic
Answer:
26.
Step-by-step explanation:
You just have to do 22.10 ÷ 0.85.
Final answer:
By dividing the total cost spent on drinks by the cost of each drink ($22.10 ÷ $0.85), we find that 26 people attended the Lopez family picnic.
Explanation:
To determine how many people attended the Lopez family picnic, we need to divide the total cost spent on drinks by the cost of each drink. Since the Lopez family spent $22.10 on drinks and each drink cost $0.85, we perform the following calculation:
Total cost spent on drinks ÷ Cost of each drink = Number of people
$22.10 ÷ $0.85 = 26 people
Therefore, 26 people attended the Lopez family picnic.

A painting, square in shape, is placed in a wooden frame with width of 10% of the length of the side of the painting. The painting was enlarged by 10%. By what percent is the new frame bigger than the original frame if the width of the frame remains the same?
Answer:
the new frame is bigger than the original frame by 10%
Step-by-step explanation:
Let the length of the original frame be l,
then it's width is (10% of l)=[tex]\frac{10}{100}[/tex]×l
=[tex]\frac{l}{10}[/tex]
hence area of original frame=A=length×width
=[tex]\frac{l^{2} }{10}[/tex]
now the length of frame is enlarged by 10%
new lenght of frame=l+10%×l
=l+[tex]\frac{10}{100}[/tex]×l
=[tex]\frac{11}{10}[/tex]×l
width of new frame==[tex]\frac{l}{10}[/tex]
area of new frame=length×width
=[tex]\frac{11l^{2} }{100}[/tex]
percent change=((area of new frame-area of old frame)×100)÷area of old frame
=10%

Find the equations of the tangents to the curve x = 9t2 + 6, y = 6t3 + 3 that pass through the point (15, 9).
Final Answer:
The equations of the tangents to the curve[tex]\(x = 9t^2 + 6, y = 6t^3 + 3\)[/tex]that pass through the point (15, 9) are [tex]\(y = 2x - 21\)[/tex] and[tex]\(y = -2x + 51\).[/tex]
Explanation:
To find the equations of the tangents, we first substitute (x = 15) and (y = 9) into the parametric equations[tex]\(x = 9t^2 + 6\)[/tex] and [tex]\(y = 6t^3 + 3\)[/tex]. Solving for (t), we get (t = 1) and (t = -1). These values of (t) correspond to the points of tangency.
Next, we find the slopes of the tangents by taking the derivatives of (x) and (y) with respect to (t), resulting in (dx/dt = 18t) and (dy/dt = 18[tex]t^2[/tex]). At (t = 1), the slope is (18), and at (t = -1), the slope is (-18).
Using the point-slope form of a linear equation [tex]\(y - y_1 = m(x - x_1)\)[/tex], where (m) is the slope and [tex]\((x_1, y_1)\)[/tex] is the point of tangency, we obtain the equations of the tangents: (y - 9 = 18(x - 15)) and (y - 9 = -18(x - 15)). Simplifying these expressions yields (y = 2x - 21) and (y = -2x + 51).
What is the first step when solving this equation?
Answer:
Distribute
When you have an equation like this, distribute first and then add or subtract like terms to solve for x.
Hope this helps!!
Well, you need to find out what x is equal to, if anything.
The first step to completing it, from what I've learned, is to do the problem that is in parenthesis first.

A doctor takes a sample of Laura’s blood. There are 4.5*10^6 red blood cellsand 5000 white blood cells. How many times more red blood cells are there than white in the sample? (Answer in scientific notations)
Number of red blood cells = [tex]4.5*10^{6}[/tex]
Number of white blood cells = 5000 or we can write this as [tex]5*10^{3}[/tex]
We have to find how many times more red blood cells are there than white in the sample. so we will divide the two to get the answer.
[tex]\frac{4.5*10^{6}}{5*10^{3}}[/tex]
= [tex]0.9*10^{3}[/tex]
= [tex]9*10^{2}[/tex] = 9*10*10 = 900
Hence, the red blood cells are 900 times more than white blood cells.
Answer:
Red blood cells are 900 times of white blood cells in the blood sample of Laura.
Step-by-step explanation:
Sample of Laura's blood sample contains number of red plus cells = 4.5[tex]10^{6}[/tex] and number of white blood cells = 5×[tex]10^{3}[/tex]
Now we calculate the ratio of red blood cells and white blood cells
= 4.5×[tex]10^{6}[/tex]÷5[tex]10^{3}[/tex]
= 4.5×[tex]10^{3}[/tex]÷5
= 4500÷5
=900

Joe's gas tank is 14 full. After he buys 6 gallons of gas, it is 58 full. How many gallons can Joe's tank hold?
Answer:
7.3 repeating
Step-by-step explanation:
58-14
=44
44/6
=7.3 repeating
Answer:
Amount of gas that can be hold by Joe's tank = 16 gallons.
Step-by-step explanation:
Given that Joe's gas tank is 1/4 full. After he buys 6 gallons of gas, it is 5/8 full. Now we need to find about how many gallons can Joe's tank hold.
So let's find change that happened after filling the gas.
Change = (5/8 full) - (1/4 full)
Change = (5/8 - 1/4) full
Change = (5/8 - 2/8) full
Change = (5 - 2)/8 full
Change = 3/8 full
So that means 3/8 full happens in 6 gallons
then 1 full will happen in 6/(3/8) gallons = 6*(8/3) gallons = 48/3 gallons = 16 gallons
So the amount of gas that can be hold by Joe's tank = 16 gallons.

a)Estimate 49% of 162. b) Use mental math to calculate 49% of 162. plz help i need to know fast
Answer:
(a)
Given expression: 49% of 162
we can write 49% as [tex]\frac{49}{100}[/tex]
then;
[tex]\frac{49}{100} \times 162 = \frac{49 \times 162}{100} = \frac{7938}{100}=79.38[/tex]
Therefore, the estimate of the given expression is, 79.38.
(b)
Using mental math to calculate 49% of 162.
Mental math is used as a way to calculate an estimate quickly.
We can write 49% = 50% -1%
(50%-1%) of 162 = 50% of 162 -1% of 162
so,
50% of 162 = [tex]\frac{50}{100} \times 162 = \frac{1}{2} \times 162 = 81[/tex]
and
1% of 162 = [tex]\frac{1}{100} \times 162 = \frac{162}{100} = 1.62[/tex]
Now, subtract these we get;
81 - 1.62 = 79.38
Therefore, by using mental math 49% of 162 is, 79.38
