A right triangle has legs that measure 7 cm and 6 cm. What is the length of the hypotenuse in meters?
Answer:
[tex]\sqrt{85} or 9.22[/tex]
Step-by-step explanation:
You need to remember the following equation:
[tex]a^{2} + b^{2} = c^{2}[/tex]
Where a and b is the lengths of the two sides and c is the hypotenuse.
So simply plug these values into this:
[tex]6^{2} + 7^{2} = h^{2}[/tex]
36 + 49 = h^2
36 + 49 = 85
So the hypotenuse is the square root of 85:
[tex]\sqrt{85} = 9.22[/tex]

Find the slope-intercept form of the line passing through the point (7,-2) and parallel to the line y=-8x-4.
The slope-intercept form of the line passing through the point (7, -2) and parallel to the line y = -8x - 4 is y = -8x + 54. The required answer is y = -8x + 54.
To find the slope-intercept form of a line parallel to the given line, we need to determine the slope of the given line first.
The given line has a slope of -8 since it is in the form y = mx + b, where m represents the slope.
Since the line we are looking for is parallel to the given line, it will have the same slope of -8.
Now, we can use the point-slope form of a linear equation to find the equation of the line passing through the point (7, -2) with a slope of -8:
y - y1 = m(x - x1)
Substituting the values of the point and slope:
y - (-2) = -8(x - 7)
Simplifying:
y + 2 = -8x + 56
Rearranging the equation to the slope-intercept form:
y = -8x + 54
Therefore, the slope-intercept form of the line passing through the point (7, -2) and parallel to the line y = -8x - 4 is y = -8x + 54. The required answer is y = -8x + 54.

Zoe rounded 6 * 8493 to 6 * 8000. Andrew rounded 6 * 8493 + 6 * 9000 who will have an estimate closer to the actual product? How do you know? Explain another way to estimate 6 * 8493 that would give a better estimate
Answer: Zoe is closer to the actual product because 6.80 is closer to 6.8493 than 6.90 mathematically. Another way to estimate 6.8493 is to round to the nearest hundredth place: 6.85
Zoe will have an estimate closer to the actual product.
Explanation:To determine who will have an estimate closer to the actual product, we can compare the rounding methods used by Zoe and Andrew. Zoe rounded 6 * 8493 to 6 * 8000, while Andrew rounded 6 * 8493 + 6 * 9000. In this case, Andrew's estimate will be closer to the actual product because he considered additional terms in his calculation.
Another way to estimate 6 * 8493 that would give a better estimate is to round each term separately before multiplying. For example, rounding 6 to 10 and 8493 to 8500, the estimate would be 10 * 8500 = 85,000.

A student has 20 pencils at the beginning of the school year. After a week, the student has 18 pencils left. If the student continues to use pencils at the same rate, which equation will represent pencils left after w weeks?
Answer: p = -2w + 20
Step-by-step explanation:
If the student had 20 pencils but now has 18 pencils, he uses pencils at a rate of 2 per week. So, m = -2 (negative because he is decreasing the amount of pencils). The student started with 20 pencils so b = 20
Use the y = mx + b but replace "y" with "p" and replace "x" with "w" and input the m and b as stated above:
p = -2w + 20
The probability that a student at certain high school likes art is 36%. The probability that a student who likes art also likes science is 21%. Find the probability that a student chosen at random likes science given that he or she likes art. Round to the nearest tenth of a percent.
Answer: Probability that a student chosen at random likes science given that he or she likes art is 58%
Step-by-step explanation:
Since we have given that
Probability that a student who likes art and science = 21%
Probability that a student who likes art = 36%
According to question,
we need to find the probability that a student chosen at random likes science given that he or she likes art.
So, we will use "Conditional Probability":
P(A) = 0.36
P(S ∩ A) = 0.21
[tex]P(S\mid A)=\frac{P(S\cap A)}{P(A)}\\\\P(S\mid A)=\frac{0.21}{0.36}\\\\P(S\mid A)=0.58\\\\P(S\mid A)=58\%[/tex]
Hence, Probability that a student chosen at random likes science given that he or she likes art is 58%.

2÷9=2/9Caiden earned $475 from mowing lawns last summer. He deposited this money in an account that pays an interest rate of 3.8% compounded annually. What will be his balance after 15 year?
Answer:
The balance after 15 year is $831.25 .
Step-by-step explanation:
Formula
[tex]Amount = P (1 + r)^{t}[/tex]
Where P is the principle and r is the rate of interest in the decimal form and t is the time.
As given
Caiden earned $475 from mowing lawns last summer.
He deposited this money in an account that pays an interest rate of 3.8% compounded annually.
Here
P = $475
3.8% is written in the decimal form.
[tex]= \frac{3.8}{100}[/tex]
= 0.038
r = 0.038
t = 15 years
Put in the formula
[tex]Amount = 475 (1 + 0.038)^{15}[/tex]
[tex]Amount = 475 (1.038)^{15}[/tex]
[tex]Amount = 475\times 1.75(Approx)[/tex]
Amount = $831.25
Therefore the balance after 15 year is $831.25 .
Caiden will have approximately $850.91 in his account after 15 years of interest compounded annually at a rate of 3.8%.
Explanation:In this problem, we're dealing with compound interest, not simple interest. The formula to calculate compound interest is: A = P (1 + r/n)^(nt), where A is the amount of money accumulated after n years, including interest; P is the principal amount (the initial money); r is the annual interest rate (in decimal); n is the number of times that interest is compounded per year; and t is the time the money is invested for in years. In this case, P equals $475, r equals 3.8/100 or 0.038 (transforming percentage to decimal), n is 1 (because the interest is compounded annually), and t is 15 years. Substituting these values into the formula gives: A = $475 (1 + 0.038/1)^(1*15). Calculate the bracketed part first, resulting in a figure around 1.038 and raise it to the power of 15, so we get a value around 1.7914. Multiply this by the initial amount of $475 to get the final balance after 15 years which will be approximately $850.91. Hence, Caiden will have $850.91 in his account after 15 years.

There is a line whose slope is 0 and whose y -intercept is 9. What is its equation in slope-intercept form?
Answer:
y = 0x + 9
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m = 0 and c = 9, hence
y = 0x + 9
The equation of a horizontal line is normally written as y = 9
with the x- term omitted
The equation of a line with a slope of 0 and a y-intercept of 9 is y = 9, which represents a horizontal line on the graph.
The student is asking about the equation of a line in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. Given that the slope (m) is 0, and the y-intercept (b) is 9, the equation of the line is simply y = 0x + 9. Since any number multiplied by zero is zero, this simplifies to y = 9.
Therefore, the equation of the line with a slope of 0 and a y-intercept of 9 in slope-intercept form is y = 9. This represents a horizontal line that crosses the y-axis at 9.

The cost of a taxi ride is equal to $3.50 plus $0.25 for each mile. If a ride costs a total of $6.75 how long was the ride?
Answer:
13 miles
Step-by-step explanation:
Write and solve an equation involving this information, using x as the distance traveled, in miles:
Cost(x) = $6.75 = $3.50 + ($0.25/mile)x
First, subtract $3.50 from both sides, obtaining: $3.25 = ($.25/mile)x.
Next, divide both sides by $0.25/mile:
$3.25
x = ------------------ = 13 miles
$0.25/mile
The length of the taxi ride was 13 miles.

Write the equation of a line that passes through the points (0, -2) and (4, -5). Answer MUST be in standard form: Ax + By = C.
The slope-intercept form:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept → (0, b).
We have the points (4, -5) and (0, -2) → y-intercept → b = -2.
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Substitute:
[tex]m=\dfrac{-2-(-5)}{0-4}=\dfrac{-2+5}{-4}=\dfrac{3}{-4}=-\dfrac{3}{4}[/tex]
Therefore we have the equation of a line
[tex]y=-\dfrac{3}{4}x-2[/tex]
Convert to the standard form: [tex]Ax+By=C[/tex]
[tex]y=-\dfrac{3}{4}x-2\qquad\text{multiply both sides by 4}\\\\4y=-3x-8\qquad\text{add 3x to both sides}\\\\\boxed{3x+4y=-8}[/tex]
So for this, I will be putting the equation into slope-intercept form then rearranging it into standard form. Firstly, we need to solve for the slope. To do this, take the 2 coordinates given to us and solve as such:
[tex]\frac{-5-(-2)}{4-0}=-\frac{3}{4}[/tex]
Now, one of the coordinates given to us is (0,-2), which is the y-intercept. With all this info, our slope-intercept equation is [tex]y=-\frac{3}{4}x-2[/tex] . From here we can solve for the standard form.
Firstly, add 3/4x onto both sides of the equation:
[tex]\frac{3}{4}x+y=-2[/tex]
Now, it may appear that we are finished. However, 3/4 is not an integer (Integers are whole numbers). To make it an integer, we need to multiply both sides by 4:
[tex]3x+4y=-8[/tex]
Answer:In short, the standard form of this equation is 3x + 4y = -8.
