Answer:
The radius will be half of your diameter so,
since 26 is your diameter half of that is = 13 is your new radius.
Now finding the area:
13^2 = 169
169 x 3.14 = 530.66 cm2 is your area.
Formula of an area of a circle:
πr^2
pi(3.14 or 22/7 depending on whatever they tell you to use for pi) x radius being squared
Find the student’s error in solving the following inequality.
31 < –5x + 6
25 < –5x
–5 < x
The student should have added 6 to both sides instead of subtracting it.
The student divided 25/–5 incorrectly.
The student should have switched the direction of the inequality sign to get –5> x for a final answer.
Answer:
The student should have switched the direction of the inequality sign to
get –5 > x for a final answer.
Step-by-step explanation:
When multiplying or dividing an inequality by a negative "flip" the inequality sign
The student should have switched the direction of the inequality sign to
get –5 > x for a final answer.

Note:
For a more conventional appearance the entire inequality can be flipped to
–5 < x
Jose is trying to pick out an outfit for the first day of school. He can choose from 2 pairs of pants, 6 t-shirts, and 3 pairs of shoes. How many different outfits does Jose have to choose from?
Jose has to choose from 36 different ways.
What is the Combination?The various ways in which objects from a set may be selected, generally without replacement to form subsets is known as combination.
For the given situation,
Pairs of pants = [tex]2[/tex]
T-shirts = [tex]6[/tex]
Pairs of shoes = [tex]3[/tex]
The formula to find the number of ways using combination = [tex]nC_{r}[/tex]
Number of ways of picking the outfit = [tex](2C_{1}) (6C_{1}) (3C_{1} )[/tex]
⇒ [tex](2)(6)(3)[/tex]
⇒ [tex]36[/tex]
Hence we can conclude that Jose has to choose from 36 different ways.

Given y varies inversely as x, and y = 5 when x = 9. Write the inverse function
Answer:
y = 45/x
Step-by-step explanation:
Given y varies inversely as x, then;
y = k/x
If y = 5 when x = 9
5 = k/9
k = 5*9
k = 45
Substitute into the formula above;
y = k/x
y = 45/x
Hence the required inverse function is y = 45/x

3x+2y=12 2x-3y=21 elimination please solve with answer and steps
Answer:
(6,-3)
or
x=6 y= -3
Step-by-step explanation:
Taking a quick look at this question we notice that we simply cannot add/subtract the two equations and eliminate a variable
What we can do is mulitply an equation to make the above true
let's try to get the first equation to have a 3y, and we can do this by multiplying it by 1.5 (this is legal because we do it to both sides)
So our new first equation is
1.5(3x+2y)=12*1.5
which simplifies to
4.5x+3y=18
We then add the two equatiosn
(4.5x+3y)+(2x-3y)=18+21
6.5x=39
x=6
Now that we know x we can plug that in and solve for y
3(6)+2y=12
18+2y=12
-6=2y
y= -3
Jake has a 34% batting average. If Jake gets up to bat 10 times in one game, what is the BEST estimate of how many times he will hit the ball?
Answer:
Approximately 3 times, Jake will be able to hit the ball in a game of 10 balls
Step-by-step explanation:
Batting average determine the % share of time the bat hit the ball.
Jake's probability of hitting a ball = 0.34
Jake plays 10 games.
Probability of hitting a ball in a game is
10 * 0.34 = 3.4
Approximately 3 times, Jake will be able to hit the ball in a game of 10 balls

Ted ate 3 pieces of the pizza. what is the area of the remaining pizza if the diameter of the pizza is 18 inches?
A. 95.4 square inches
B. 381.7 square inches
C. 159.0 square inches
D. 636.2 square inches.
Answer:
C. 159.0 square inches
Step-by-step explanation:
Given that
Ted ate 3 pieces of the pizza
We need to find out the area of the remaining pizza in the case when the pizza diameter is 18 inches
Since the large circular pizza is divided into 8 equal slices
Now the radius of a pizza is
= 18 ÷ 2
= 9 inches
Now the angle subtended by each pizza is
= 360 degrees ÷ 9 inches
= 45 degrees
Now the area of the each pizza is
= [tex]\theta[/tex] ÷ 360 × πr^2
= 45 ÷ 360 × 3.14 × 9^2
= 31.7925
Now the area of the remaining pizza is
= 5 × 31.7925
= 158.9625
= 159 square inches

The black trapezoid is a dilation of the green trapezoid. What is the scale factor of the dilation?
A) 1/5
B) 1/3
C) 3
D) 5
============================================================
Explanation:
We're told that "The black trapezoid is a dilation of the green trapezoid". This means the black trapezoid is the image, while the green one is the preimage. In other words, the green is the "before" and the black is the "after". The mapping is [tex]\text{green} \to \text{black}[/tex] because of the ordering [tex]\text{preimage} \to \text{image}[/tex]
Since the green figure (preimage) is larger than the black figure (image), the scale factor must be some value k such that 0 < k < 1. That narrows the answer choices between A and B.
Focus on the green trapezoid. The bottom left corner is at (-10,0). The bottom right corner is at (5,0). The distance between these two points is 15 units.
Using the same idea, the distance along the bottom edge of the black trapezoid is 3 units. We can count out the spaces along the bottom, or we can note the two bottom corners are at (-2,0) and (1,0).
------------------------------
So far we found:
The bottom edge of the green trapezoid is 15 unitsThe bottom edge of the black trapezoid is 3 unitsThese two edges correspond to one another. We divide the values to get the scale factor. We divide the image length over its corresponding preimage length.
scale factor = (image length)/(preimage length)
scale factor = 3/15
scale factor = 1/5

Answer:
Step-by-step explanation:
8√42 ÷ 2√7 is 8√42/2√7 in a fraction form
you want to take the square root out of the denominator, and so you would multiply the denominator by the numerator and itself.
8√42/2√7 * 2√7/2√7 = 4√6

Colin invests £1100 into his bank account. He receives 5% per year simple interest. How much will Colin have after 6 years? Give your answer to the nearest penny where appropriate.
Answer:
Step-by-step explanation:
P = £1100
r = 5%
t = 6 years
I =P*r*t
[tex]I =1100*\frac{5}{100}*6\\\\I=11*5*6\\\\I = 330[/tex]
Amount = P + I = 1100 + 330 = £1430
mDE = 128 and mBC = 63. Find mZA. (The figure is not drawn to scale.)
Answer:
The angle formed by the intersection of 2 secants could be found out as: 1/2 (Arc DE - arc BC)
mDE = 128
mBC = 63
=> 1/2 (128 - 63)
=> 32.5 = mZA
