Answer:
<CPE= 137
Step-by-step explanation:
In order to find the measure of (<CPE), one must add the measure of <(CPD) and (<DPE). From the given picture, one can infer that line (CA) is a diameter. This means that the sum of all angles on either side of the line is (180). Therefore, to find the measure of (<DPE) add up all of the angle measures on one side of the line, and set it equal to (180). Solve and then add the result to the value of (<CPD) to find the measure of (<CPE).
(<CPD) + (<DPE) + (<EPA) = 180
Substitute,
88 + (<DPE) + 43 = 180
Simplify,
131 + (<DPE) = 180
Inverse operations,
<DPE = 49
Now add the value of (<DPE) to (<CPD),
(<CPD) + (<DPE)
= 88 + 49
= 137

I'm assuming you want to answer problem 5.
If so, then the answer is A = 84 degrees
==========================================================
Explanation:
Minor arc BC is 96 degrees. This is the measure along the edge of the curve from B to C, following the shorter path. You correctly identified that the central angle BKC is also congruent to this arc measure, since the central angle cuts off this arc.
Because segments AB and AC are tangents to the circle, this makes the segments to be perpendicular to the radii that meet at the point of tangency. In other words, AB is perpendicular to BK, and AC is perpendicular to CK.
Ignore line BC. Focus on quadrilateral ABKC. So far we know that
angle K = 96angle B = 90angle C = 90The only thing missing is angle A, which is what we're after. Recall that for any quadrilateral, the four interior angles always add to 360 degrees.
So,
A+B+K+C = 360
A+90+96+90 = 360
A+276 = 360
A = 360-276
A = 84
-----------------------
Or as a shortcut, you can use the property that because B and C are right angles, this means we have 360-B-C = 360-90-90 = 180 degrees left for angles A and K to add to. This makes angle A and angle K to be supplementary.
So,
A+K = 180
A+96 = 180
A = 180-96
A = 84

The vectors VN−→{−8;3} and MT−→{2;10} are given. Calculate: 7⋅VN−→3⋅MT−→ =
Answer: { ; }.
Answer:
Step-by-step explanation:
To calculate 7⋅VN−→3⋅MT−→, we need to perform scalar multiplication on the two vectors. Scalar multiplication is simply multiplying each of the components of the vector by the scalar value.
So for the first vector, we have: 7⋅VN−→ = {7⋅(-8); 7⋅3} = {-56; 21}.
For the second vector, we have: 3⋅MT−→ = {3⋅2; 3⋅10} = {6; 30}.
Then to add the two vectors, we simply add the corresponding components: {-56; 21} + {6; 30} = {-50; 51}.
Therefore, the final result is {-50; 51}.

bills, 80 quarters, 32 dimes, 95 nickels, and 5 pennies. He would like to
receive $40.00 in cash.
The total cost of Jess Norton is $995.85 and the total cost of Olive Baker is $678 .
What is total cost ?
The total cost formula is used to total up the variable and constant expenses associated with providing commodities. Total cost = (Average Fixed Cost x Average Variable Cost) x Units Produced is the formula.
In economics, total cost is the total of all expenses a company incurs to produce a particular level of output.
The average cost, or the typical sum of money required to create a unit, can be determined using the cost function. The average cost function is A(x)=C(x)x, where x > 0 and C is the constant. Calculating the average cost per unit requires dividing the total cost by the quantity of units produced.
For Jees Norton,2 one hundred dollar bills = 2 x $100
= $200
Total deposits = 2 one hundred dollar bills + Checks
= $200 + $474.85 + $321
= $995.85
For Olive Baker,
Checks amount = $100 x 4
= $400
12 for $7.5
= 12 x $7.5
= $90
Six 20-dollar bills = 6 x $20
= $120
Five 10-dollar bills = 5 x $10
= $50
Eighteen 1-dollar bills = 18 x $1
= $18
Total deposits = $400 + $90 + $120 + $50 + $18
= $678

spider monkey: {12, 13, 13, 14, 14, 14, 16, 16}
(a) Calculate the mean and MAD for each type of monkey.
(b) Calculate the means-to-MAD ratio for the two types of monkeys.
(c) What inference can be made about the weight of both types of monkeys? Explain.
when answering please seperate the answers with either 1, 2, 3 or a, b, c! thank you
Answer:The mean for the howler monkeys is 17 and the MAD is 0.8571.
The mean for the spider monkeys is 14 and the MAD is 1.1429.
The means-to-MAD ratio is 2.6249.
Step-by-step explanation:
To find the mean of the howler monkeys, add all of the data values and divide by 7:
(15+16+17+17+17+17+18+19)/7 = 119/7 = 17
To find the MAD, subtract each data point from the mean; take the absolute deviation; then average these together:
(|15-17|+|16-17|+|17-17|+|17-17|+|17-17|+|17-17|+|18-17|+|19-17|)/7
=(2+1+0+0+0+0+1+2)/7=6/7 = 0.8571
Repeating these processes for the spider monkeys:
Mean:(12+13+13+14+14+14+16+16)/7 = 98/7 = 14
MAD:
(|12-14|+|13-14|+|13-14|+|14-14|+|14-14|+|14-14|+|16-14|+|16-14|)/7
=(2+1+1+0+0+0+2+2)/7 = 8/7 = 1.1429

The triangle ABC, along with it's image after the reflection x = -3, is given on the graph presented at the end of the answer.
How to obtain the image of the triangle?The coordinates for the original vertices of the triangle are given as follows:
A(-5, -6), B(-4, -3) and C(-3,-7).
The reflection line is given as follows:
x = -3.
The reflection lines is a vertical line, meaning that for the reflected triangle, the y-coordinate remains constant, while the x-coordinate means that the triangles will be on the same distance relative to the reflected line, however on the opposite direction.
Vertex A has a x-coordinate two units left of x = -3, hence the coordinates of the image will be two units right, hence:
A'(-3 + 2, -6) = (-1, -6).
Vertex B has a x-coordinate one unit left of x = -3, hence the coordinates of the image will be one unit right, hence:
B'(-3 + 1, -3) = B'(-2,-3).
Vertex C remains at the same position, as it has a x-coordinate of -3.

by splanation, in be clearly what he taking about. the hamburger, usually. is 1/4 p.1/2 p. in triple hamburger on 4 by 4
The number of used hamburgers that is 80% lean is = 500
and the number of used hamburgers that is 88% lean is = 300.
Let the number of hamburger that is 80% lean be = x.
So the number of hamburger that is 88% lean is = 800 - x
According to question after the mixing all these the total percentage of lean in 800 ponds of burgers is 83%.
So, the suitable mathematical equation is,
80% of x + 88% of (800 - x) = 83% of 800
(80/100) x + (88/100) * (800 - x) = (83/100) * 800
80x + 88 (800 - x) = 83 * 800 [Multiplying 1000 with both sides]
80x + 88 * 800 - 88x = 83 * 800
88x - 80x = 88 * 800 - 83 * 800 = 800 (88 - 83) = 5 * 800
8x = 800 * 5
x = (800 * 5)/8 = 100 * 5 = 500
Hence the number of hamburger with 80% lean is 500 and the number of hamburger with 88% lean is = (800 - 500) = 300.
