Answer:
A, [tex]\sqrt{17}[/tex]
Step-by-step explanation:
a^2 + b^2 = c^2
8^2 + b^2 = 9^2
64 + b^2 = 81
b^2 = 17
b = [tex]\sqrt{17}[/tex]
Answer:
by pythagoras theorem
9² = 8² + x²
x² = 81 - 64
x² = 17
x = root 17
option A

Write an equation in slope intercept form that goes through (-1,6) and (3,-2)
Answers
First, we need to use slope formula* to find the slope.
[tex]m = \frac{-2 - 6}{3 - (-1)} = \frac{-8}{4} = -2[/tex]
Second, we use the slope we found and ONE of the 2 points listed and plug it into slope-intercept form** to solve for b.
Here is what we have so far:
[tex]m = -2[/tex]I'm going to use this point:
[tex]x = 3[/tex][tex]y = -2[/tex]Here is how to find b:
[tex]-2 = -2(3) + b\\\\-2 = -6 + b\\\\4 = b[/tex]
Finally, we put all of it together and we have our equation.
[tex]y = -2x + b[/tex]
*Slope formula: m = y₂ - y₁/x₂ - x₁

What is the least common multiple of the numbers 5, 25, and 15? OA. 25 OB. 50 O C. 75 OD. 100 O E. 125
Answers
Explanation: Let’s go from smallest to largest.
A, 25, would not work because you can’t multiply 15 by a whole number to get 25.
B, 50, doesn’t work because again, you can’t multiply 15 with a whole number to get 50.
C, 75, is the CORRECT ANSWER because 5x15 is 75, 25x3 is 75, and 15x5 is 75. Each number can be multiplied by a whole number to get 75.

Please check the attached figure!
Step-by-step explanation:
Part a)
Point A is located at the x-coordinate x=-4 and y-coordinate y=1.
Hence, the coordinates of point A = (-4, 1)
Part b)
Point B(3, -2) has been plotted and is shown in the attached figure.
It is clear from the attached diagram that point B is located at the x-coordinate x=3 and y-coordinate y=-2. Hence, the coordinates of point B = (3, -2)
Part C)
Point C has the same x-coordinate as point A i.e. x=-4 and the same y-coordinate as point B i.e. y=-2.
Hence, the coordinates of point C = (-4, -2). Point C is also plotted as shown in the diagram.

Ok, you should first order every number in the regular order (1,2,3,4,5,6,7,and so on) or (1.2,1.3,2.4,5.9).

Median means the exact middle and here there are total of 15 different numbers so we know this is going to be easier if this was even. 50.7 is the median because it is in the middle and there are an even number of numbers on each side to it, 7.

Use quadratic formula to solve 1-6x^2-x
Answers
Answer:
(3x-1)(2x+1)
Step-by-step explanation:
1-6x^2-x=0
-6x^2-x+1=0
6x^2+x-1=0
6x^2+(3-2)x-1=0
6x^2+3x-2x-1=0
3x(2x+1)-1(2x+1)=0
(3x-1)(2x+1)=0
So the factor is (3x-1)(2x+1)

y - y1 = m(x - x1)
substitute:
y + 8 =-5/4(x - 8)
-5/4 = -1.25
y + 8 = -1.25 ( x - 8)

y + 8 = -1.25x + 10
subtract 8 from both sides:

Answers
Answer:4610
Step-by-step explanation:
$4564 is the amount in account after 5 years.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that Madison invested $3,300 in an account paying an interest rate of 6.7% compounded daily.
We need to assume no deposits or withdrawals are made, then we need to find money in account after 5 years.
Madison invested = $ 3300
Rate of interest = 6.7 %
Time = 5 years
[tex]A=P(1+\frac{r}{100} )^{t}[/tex]
P is the principle amount
t is the time
r is the rate of interest
[tex]A=3300(1+\frac{6.7}{100} )^{5}[/tex]
A=3300(1+0.067)⁵
A=3300(1.067)⁵
A=3300(1.383)
A=4563.9
A=4564
Hence, $4564 is the amount in account after 5 years.

Brad has $10 to spend at Ruby's. He orders 1/2 pound of sausage and 11/4 pound of chicken. How much money will Brad have left after he pays for his order?
Answers
Answer:
Step-by-step explanation:
Brad will have $5.24 left after he pays for his order.
What is unit rate?A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.
Given that, Brad has $10 to spend at Ruby's. He orders 1/2 pound of sausage and 11/4 pound of chicken.
Price of sausage per pound (unit rate) = $3.25
Therefore, price of 1/2 pounds of sausages = $3.25×0.25 = $1.63
Price of chicken per pound (unit rate) = $2.50
Therefore, price of 1 1/4 pounds of sausages = $2.50 × 1.25 = $3.13
Total the amount he spent at Ruby's = $1.63+$3.13 = $4.76
Amount left after payment = $10-$4.76
= $5.24
Hence, Brad will have $5.24 left after he pays for his order.

Lin's father spent $20 on ice cream for the family. He had to pay a 7% sales tax. What was the total cost of the ice cream? $
*Hint: be sure to include 2 decimal places to show the cents*
Answers
Answer:
6%→0.06
Now, we need to multiply the pre-tax cost of this item by this value in order to calculate the sales tax cost.
\textup{Sales tax}=0.06\times\$2.35
\textup{Sales tax}=\$0.141
Round to two decimal places since our total is in dollars and cents.
\textup{Sales tax}=\$0.14
Last, add this value to the pre-tax value of the item to find the total cost.
\textup{Total cost}=\textup{Pre-tax value}+\textup{Sales tax}
\textup{Total cost}=\$2.35+\$0.14
\textup{Total cost}=\$2.49
