What is the diameter of the following circle
Answer:
d = 140 in
Step-by-step explanation:
Remember that d = 2r. If r = 70 in, then d = 140 in
11. In circle R. BC = 5 and CE = 12
Which values are not possible lengths for segments AC and CD,
respectively?
В
A. 6 and 10
B. 3 and 20
C. 4 and 15
D. 12 and 13
Answer:
D) 12 and 13
Step-by-step explanation:
BC x CE = AC x CD
5 x 12 = AC x CD
60 = AC x CD
A) 6 x 10 = 60, yes
B) 3 x 20 = 60, yes
C) 4 x 15 = 60, yes
D) 12 x 13 ≠ 60, so no
The values that are not possible lengths for segments AC and CD,
is 12 and 13
Option D is correct
Chords in a circle :when two chords intersects in a circle , then the product of the length of segments of the chords are equal
Product of chordsFrom the given circle , the product of the measure of the segments are equal
[tex]AC \cdot CD= BC \cdot CE[/tex]
In circle R, BC = 5 and CE = 12
Substitute the values inside the formula.
[tex]AC \cdot CD= BC \cdot CE\\AC \cdot CD= 5 \cdot 12\\AC \cdot CD= 60[/tex]
Now we look at the options and see which one gives the product 60
[tex]6 \cdot 10=60\\3 \cdot 20=60\\4 \cdot 15= 60\\12 \cdot 13= 156[/tex]
The values that are not possible lengths for segments AC and CD,
is 12 and 13 because the product is 156 not 60.

Find the shaded area. Leave your answers in terms of PI.
Answer choices:
4π
64π
6π
8π
Answer:
8π cm^2
Step-by-step explanation:
Here's your solution
=> Area of biggest circle = πr^2
=> Area = 16π cm^2
=> Area of small circle = 4π cm^2
=> there are two circles hence both area =
8π cm^2
=> now, Area of shaded region = 16π cm^2 - 8π cm^
=> Area = 8π cm^2

What’s the answer??
Given f (x) = 6x2 and g(x) = 3x +4, find g (f (4)).
Answer:
292
Step-by-step explanation:
Given
f(x) = 6x²
g(x) = 3x + 4
Now.
f(4) = 6 * 4²
= 6 * 16
= 96
Now
g(f(4) = g( 96)
= 3 * 96 + 4
= 288 + 4
= 292

Mrs.Lamb’s favorite candy bar weight 3 ounces. If a box contains 150 of these candy bars, what is the weight, In pounds, of this box of candy? ( 1 pound = 16 ounces)
Answer:
28.125
Step-by-step explanation:
A bar weights 3 ounces, she has a box of 150 so you multiply
150 times 3 = 450
well one pound equals 16 ounces, so you divide
450 divide by 16 = 28.125

Which is a zero of the quadratic function f(x) = 9x2 – 54x – 19?
x = 1/3
x = 3 1/3
x = 6 1/3
x = 9 1/3
Answer: Third Choice. x= 6 1/3
Step-by-step explanation:
Given
f(x) = 9x² - 54x - 19
Completing the square
3x -19
3x 1
Substitute back to the function
f(x) = (3x-19) (3x+1)
Simplify
x= 6 1/3 or -1/3

The measure of angle L from the given triangle KLM is 57°.
What is sine rule?Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
The formula for sine rule is sinA/a=sinB/b=sinC/c. Where, A=angle A, a=length of side a, B=angle B, b=length of side b, C=angle C and c=length side c.
Given that, in ΔKLM, l = 570 cm, k = 490 cm and ∠K=46°.
By using sine rule in the triangle KLM, we get
sinL/l=sinK/k
sinL/570=sin46°/490
Here, sin46°=0.7193
sinL/570=0.7193/490
sinL/570=0.001467
sinL=0.8367
∠L=sin⁻¹(0.8367)
∠L=57°
Therefore, by using sine rule the measure of angle L is 57°.

If I roll a dice 120 times how many times I expect to get a 2
Answer:
If one rolls a dice 120 times, he/she expect to get a 2, 20 time
Step-by-step explanation:
The probability of getting a 2 when the dice is rolled 1 time is [tex]\frac{1}{6}[/tex]
Given - The dice is rolled for 120 times
Probability of getting a 2 is
[tex]\frac{1}{6} *120\\= 20[/tex]
Thus, if one rolls a dice 120 times, he/she expect to get a 2, 20 time

Olive is allowed to bring one friend on a trip with her.
She does not want to play favorites.
What is NOT a random method of choosing a friend? what’s is NOT a random method of choosing a friend
Answer:
Process of elimination
Step-by-step explanation:
If Olive wants to choose a friend while not playing favorites, while also not being random, she has to eliminate the ones she knows she will NOT take on the trip. She can choose this by selecting the one she knows that will be best on the trip with her, depending on the situation.
Or, if Olive only has one friend, then it wouldn't be surprising that she would take that one friend on the trip, since she has no one else to choose. This way, it is not playing favorites, nor is it random. Hope this helps you!

Mary makes trait mix with bulk nuts and dried fruit. She spends on the dried fruit Mixed nuts cost $2.50 per pound. She has a total of $12 to spend
How many pounds of nuts can she buy?
Answer:
4 pounds
Step by Step Explaintion
The required Mary can buy 4 pounds of mixed nuts with her remaining budget.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
If Mary has a total of $12 to spend and she spends $2.50 on dried fruit, then she has $12 - $2.50 = $9.50 left to spend on mixed nuts.
If mixed nuts cost $2.50 per pound, then Mary can buy $9.50 / $2.50 per pound = 3.8 pounds of mixed nuts.
However, since Mary cannot buy a fraction of a pound, the actual amount of mixed nuts she can buy will be limited to the nearest whole number.
Therefore, Mary can buy 4 pounds of mixed nuts with her remaining budget.
