Answer:
D is incorrect
Step-by-step explanation:
If you know the measure of two angles of a right triangle and you only one length of a right triangle then you will be able to ONLY find the length of the third angle of a right triangle and not the other two sides.
Cheddar cheese cost 5.25$ per pound. Which equation best represents y, the total cost of x pounds of cheddar cheese? Best answer gets brainlist
Answer: y = 5.25x
Step-by-step explanation:
The cost of one pound of cheddar cheese is $5.25.
The number of cheese purchased is x.
The total cost of cheese would therefore be the cost of one pound of cheese multiplied by the number of pounds of cheese purchased:
= 5.25 * x
Full expression is therefore:
y = 5.25 * x
y = 5.25x
Rewrite the function f (x) =-3(x + 2)2 + 7 in the form f(x) = ax++bx+c.
Answer:
f(x)= -3x² - 12x - 5
Step-by-step explanation:
-3(x+2)² + 7
-3(x+2)(x+2) + 7
(-3x-6)(x+2) + 7
-3x² - 6x - 6x - 12 + 7
-3x² - 12x - 5

Answer:
These methods convert everything to radians
Step-by-step explanation:
Length of arc DC fromula is radius*angle in radians
Radius of the circle of DC is 8 cm aka the outer circle.
The angle inside is 130 degrees, in radians convert and multiply by 180/[tex]\pi[/tex]
givong 130 degrees to be 13/18π
using formula, arc DC is 8*13/18π
=52/9π (in terms of pi) or 18.15 cm
or 130/360*(2π8)=18.15 (not using radians)
Length of arc QT regards the inner circle of radius 4 cm. Convert 130 degrees to radians. Using same formula as above, length of arc =4*13/18π
=26/9π or 9.08 cm
or 130/360*(2π4)=9.08 (not using radians)
Area of sector DEC suspended angle is 130 degrees of 13/18π radians. regarding large outer circle radius 8 cm.
Use formula 0.5*r^2*angle in radians fro area of sector gives:
0.5*8^2*13/18π
=208/9π or 72.61 cm^2
or 130/360*(π8^2)=72.61 (not using radians)
The area of sector QET angle 13/18πv rad and radius 4 cm using same forumla as above gives
0.5*13/18π*4^2
=52/9π or 18.15cm^2
or 130/360*(π4^2)=18.15 (not using radians)
Radian measure of angle DEC is 130 degrees again convert to radians by multiplying by π/180 gives
=13/18π
Radian measure of angle QET IS ALSO 130 degrees also
=13/18π
Madden 2020 game cost $95. Last year this game was $76. What is the
percent change in price
Answer:
25%
Step-by-step explanation:
Percentage change is the difference between the new price and the old price, divided by the old price. Finally, multiply by 100 to convert the decimal answer to percent.
Difference in prices (new - old): 95 - 76 = 19
Divide by old price: 19/76 = .25
Multiply by 100%: .25 x 100 = 25%

Y=190(1.471)^x determine the percentage of increase or decrease
Given:
The exponential function is:
[tex]y=190(1.471)^x[/tex]
To find:
The percentage of increase or decrease.
Solution:
The general exponential function is:
[tex]y=a(1+r)^x[/tex] ...(i)
Where, a is the initial value,t is the time period, r is the rate of increase if [tex]r>0[/tex] and r is the rate of decrease if [tex]r<0[/tex].
We have,
[tex]y=190(1.471)^x[/tex]
It can be written as:
[tex]y=190(1+0.471)^x[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]r=0.471[/tex]
Since [tex]r>0[/tex], therefore the given function is an increasing function.
[tex]r\%=0.471\times 100[/tex]
[tex]r\%=47.1\%[/tex]
Therefore, the percentage of increase is 47.1%.

Which of the following sets of numbers could not represent the three sides of a right
triangle?
{20, 48,52}
{40, 75, 85}
{14, 47,50}
{13, 84, 85}
Answer:
{14, 47, 50}
Step-by-step explanation:
The three sides of a right triangle must satisfy
a² + b² = c², known as the Pythagorean Theorem. So let's put the pairs into the theorem.
20, 48, 52
a² + b² = c²
20² + 48² = 52²
400 + 2304 = 2704
2704 = 2704
20, 48, and 52 represent the three sides of a right triangle.
40, 75, 85
a² + b² = c²
40² + 75² = 85²
1600 + 5625 = 7225
7225 = 7225
40, 75, and 85 represent the three sides of a right triangle.
14, 47, 50
a² + b² = c²
14² + 47² = 50²
196 + 2209 = 2500
2405 ≠ 2500
14, 47, and 50 do NOT represent the three sides of a right triangle.
13, 84, 85
a² + b² = c²
13² + 84² = 85²
169 + 7056 = 7225
7225 = 7225
13, 84, and 85 represent the sides of a right triangle.
14, 47, and 50 do NOT represent the three sides of a right triangle, therefore making it your answer.

A juice can is 16cm tall and has a diameter of 9cm. The ends of the can are tin and the body is cardboard.
What is the volume of the can?
What area of tin is used?
What area of cardboard is used?
What is the total area surface?
Answer:
a)1017.88 cm³
b)63.62 cm² (corr. to 2 d. p.)
c)452.39 cm² (corr. to 2 d. p.)
d)579.63 cm²
Step-by-step explanation:
a) Volume = π x r x h = π x (9/2) x 16 = 1017.88 cm³
b) area of tin is used = circle = π x (9/2)² = 63.62 cm² (corr. to 2 d. p.)
c) area of cardboard is used = 2 x π x (9/2) x 16 = 452.39 cm² (corr. to 2 d. p.)
d) total area surface = 2(63.62) + 452.39 = 579.63 cm²

The median score will stay at 91.
Step-by-step explanation:
First put the numbers in order from greatest to least:
87, 88, 91, 91, 95, 100
Then find the median (middle) because there are two in the middle that are the same, it's just that number.
Next, add the other numbers.
86, 87, 88, 88, 91, 91, 95, 98, 100, 100
Find the median again, which is still 91.

What is the equation in slope-intercept form of the line that crosses the x-axis at 21 and is perpendicular to the line represented by y = 7/2x-13
Given:
A line is perpendicular to the line [tex]y=\dfrac{7}{2}x-13[/tex].
The line passes through the x-axis at 21.
To find:
The equation of the line in slope intercept form.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex]
Where, m is the slope and b is the y-intercept.
The given line is:
[tex]y=\dfrac{7}{2}x-13[/tex]
So, the slope of this line is [tex]\dfrac{7}{2}[/tex].
The product of slopes of two perpendicular lines is -1.
Let m be the slope of required line. Then the slope of the required line is:
[tex]m\times \dfrac{7}{2}=-1[/tex]
[tex]m=-\dfrac{2}{7}[/tex]
The line passes through the x-axis at 21. It means the line passes through the point (21,0). So, the equation of the line is:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-0=-\dfrac{2}{7}(x-21)[/tex]
[tex]y=-\dfrac{2}{7}(x)-\dfrac{2}{7}(-21)[/tex]
[tex]y=-\dfrac{2}{7}x+6[/tex]
Therefore, the equation of the required line is [tex]y=-\dfrac{2}{7}x+6[/tex].
(PLEASE HELP) What is the area?
Answer:
The area is 2,000 cm2
Step-by-step explanation:

Remark
I hope you don't mind if I laughed a little at the graph. The y intercept of the line is at 10 dollars, but the rental car has not moved an inch. I guess they're charging you to look at your driver's license. It's late, and maybe I am a little giddy.
Begin by using a ruler (or some other straight edge) to join all the dots.
a) I'll spend a little time here. It is very important that you know how to read a chart and this question is your first step. The question is how many dollars does it take to go 40 miles? There is a system. Start with the 40 miles on the horizontal axis (x axis if you know that that is).
Use a ruler to go straight up until you hit the line.
When you hit the line, mark the place.Now move straight across until you hit the y axis where you find out the money.You should get 30 dollars.b) This question is a guess.
You can find the 70 dollars easily enough. Go straight up again until you hit the line. Mark the point on the line.Go straight across again.Not so easy. It isn't marked. You have to make a guess. My guess is 45. What do you think?c) This question is the exact reverse of the other two.
This time you start with the amount of moneySo you start at 60 dollars and go straight across until you hit the line.Mark the point.Now take your ruler and go straight down. You should hit 100 miles.HELP I NEED HELP ASAP HELP I NEED HELP ASAP HELP I NEED HELP ASAP HELP I NEED HELP ASAP HELP I NEED HELP ASAP HELP I NEED HELP ASAP HELP I NEED HELP ASAP HELP I NEED HELP ASAP

The variable g represents the number of guests, and the variable c represents the cost in dollars. If there are 10 guests, how much will Anne's retirement party cost? $
Answer:
Cost (10 guests ) = 50
Step-by-step explanation:
Given : Cost c = 10 + 4g (g refers to guests)
Equation : c = 10 + 4g
Putting no. of guests 'g' = 10
c = 10 + 4 (10) = 10 + 40
c = 50

Answer:
x = 4
Step-by-step explanation:
The image provided below, I find very helpful when trying to solve difficult problems such as this one.
We use the same relationship, the only difference is we are given expressions and numbers for the segments
If the product of the segments in one chord equal the product of the segments in the other chord then,
x * 6 = 8 * ( x - 1 )
Or 6x = 8 ( x - 1 )
Now we solve for
Step 1 distribute the 8
8 * x = 8x
8 * -1 = -8
We now have 6x = 8x - 8
step 2 subtract 8x from each side
6x - 8x = -2x
8x - 8x cancels out
we now have -2x = -8
step 3 divide each side by -2
-2x / -2 = x
-8 / - 2 = -4
we're left with x = 4
