Answer:
22in²
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Circumference = 25 (1/7)
As we know,
Circumference of a circle = 2πr
By solving this we get
Radius (r) = 4in
Now. we can calculate the area by using following formula,
Area = πr²
By putting the value, we get
Area = (22/7) × 4²
= 22/7 × 16
= 352÷16
Area = 22in²

Which function is best represented by this graph?
A. y = 1/2x + 6
B. y = −2x + 3
C. y = 2x + 6
D. y = −1/2x + 3
Answer:
d
Step-by-step explanation:
not a bc it has to be negative
not c bc its has to be negative
not b bc the slope is -1/2
IT'S D
Answer:
D
Step-by-step explanation:
from the picture, we know that the slope is negative to begin, since the line is going on a downward direction from left to right. this eliminated A and C instantly.
Now we also can see the graph crossed at 3 for the y intercept, which is another reason to eliminate A and C.
we must then find the show of the line.
let us use to point (0,3) since this is the y intercept and (6,0) since this is the x intercept. to find the slope, m, at must use the equation
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
so, let's label (0,3) as point 1 and (6,0) as point two. then,
x1 = 0
y1= 3
and
x2= 6
y2=0
Now we just plug in and simplify.
[tex] m = \frac{0 - 3}{6 - 0} = \frac{ - 3}{6} = - \frac{1}{2} [/tex]
we now have our slope and y intercept, so we can plug them into our equation
[tex]y = mx + b[/tex]
where m is the slope and b is the y intercept.
our equation is thus
[tex]y = - \frac{1}{2} x + 3[/tex]
so, the answer is D
Daryl can jump 2 1/2 yards. Sarah can jump 8 feet and Michelle can jump 72 inches.Which statement is true?
Isaac finished eight of the ten homework problems. Phil has finished of the homework. How many more problems did Isaac finish?
Answer:
-2
Step-by-step explanation:
If Issac has finished 8/10 problems in the homework, and Phil has completed all of it, it can be concluded that Phil completed 10/10. 10/10 would equal a whole, or in this case, the entire homework. If Issac completed 8 problems, and Phil completed 10, subtract both values to find that Issac completed -2 more problems than Phil.
*correct me if I'm wrong, or If I didn't fully understand your question, because I am a little confused with how much homework Phil has finished.
In a right triangle, the hypotenuse has endpoints P(–3, 2) and Q(1, –3). If R represents the third vertex in the triangle and R is located in the third quadrant, what is the length of PR?
PR = 5 units.
Step-by-step explanation:Given:
Right triangle
Hypotenuse = P(–3, 2), Q(1, –3)
R = located in the third quadrant.
To calculate the length of PR,
(i) First make a sketch of the points P and Q. The diagram is attached to this response.
(ii) As shown in the diagram, the point R is located in the third quadrant and its distance from P is from point -3 to 2 on the y-axis.
There are 5 points between -3 and 2. Therefore, the length PR = 5 units

X=15mJayna used the distributive property to simplify the expression 4(a + 2) and got(4a + 2). Do you agree with Jayna?
Answer:
No
Step-by-step explanation:
I would not agree with Jayna because using the distributive property, you can get:
4(a + 2) = 4(a) + 4(2) = 4a + 8
Jayna did not get the right answer because she did not distribute the 4 to the 2 in a + 2 and she only multiplied a by 4.

Sally can paint a room in 9 hours while it takes Steve 5 hours to paint the same room. How long would it take them to paint the room if they worked together?
Answer: About 3 hours and 5 minutes to paint the room together.
Step-by-step explanation:
Sally can paint 1/5 of the room in an hour and Steve can paint 1/8 of the room in an hour.
Room/Hour
1/5 ± 1/8 =8/40
8/40+5/40=13/40
How long to paint the room?
13/40 x 1= 40/13
40÷13=3.0777
So the answer will be Sally and Steve can paint the room in about 3 hours and 5 minutes

What is the surface area of this composite solid?
Use 11.3 meters for the slant height of the triangular prism.
Enter your answer in the box.
__m²
Composite made up of a rectangular prism surmounted by a triangular prism. The rectangular prism has dimensions of 16 meters wide by 20 meters long by 12 meters high. The triangular prism has dimensions of 16 meters wide by 20 meters long with a triangular altitude of 8 meters high.
Answer:
1764 m²Step-by-step explanation:
Refer to attached picture.
All given dimensions are given on the picture (not to scale).
Since altitude of the triangle and slant height is given, we can find the base of the triangle using Pythagorean:
[tex]b/2 = \sqrt{11.3^2-8^2} = \sqrt{64} = 8m, \\b = 16 m[/tex]It has 9 faces and the total surface area is:
S = 16*20 + 2(20*12) + 2(20*11.3) + 2(16*12) + 2(1/2*8*16) = 1764 m²cosine angle B (geometry, right triangles- giving brainliest and thanks to all!)

You start at (6, 7). You move right 3 units. Where do you end?
Answer:
(9, 7) is where you would end
Step-by-step explanation:
We know that;
x-value = 6
y-value = 7
We also know that by moving 3 units right u will add 3 to the x-value, therefore;
Final x-value = 6 + 3 = 9
Final y-value = 7 (there is no change)
Final coordinates: (9, 7)

Alice is searching online for tickets to a knicks game. Two weeks ago, the cost was $30. Now the cost is $39. What is the percent increase
Given:
Two weeks ago, the cost of tickets = $30
Now, the cost of tickets = $39
To find:
The percent increase.
Solution:
We have,
Initial value = $30
New value = $39
Formula for percentage increase is:
[tex]\%\text{increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]
Using this formula, we get
[tex]\%\text{increase}=\dfrac{39-30}{30}\times 100[/tex]
[tex]\%\text{increase}=\dfrac{9}{3}\times 10[/tex]
[tex]\%\text{increase}=3\times 10[/tex]
[tex]\%\text{increase}=30[/tex]
Therefore, the percent increase in the cost of tickets is 30%.

Someone please help 20 points!
please help me PLEASE
Answer:
The answers are A, B and C.
Step-by-step explanation:
To solve the inequality you first have to use Distributive Property. You should get -3k + (-21) > -57
Next Divide 21 on both sides. -57/21 is -36
You should have -3k > -57
Divide -3 on both sides. -57/-3 is 12
You should end up with k > 12
And you never used -5, 0 or 8 in the equation and the question asks to choose the following that isn't included in the solution so your answers are A, B and C.

If I need to pour a cement sidewalk five feet wide and 250 feet long, the cost of the cement is 30 afoot, what will I have to pay.
Answer:
$37500
Step-by-step explanation:
Given data
Width of side walk= 5ft
Lenght= 250ft
Cost per square foot= $30
Hence the area of the side walk= 5*250
= 1250ft^2
Hence the cost = 30*1250
=$37500
