Find the value of angle A and angle B
hello
so these angles you can apply the "vertically opposite angles are equal" rule
angle "A" is vertically opposite to 138º so therefore angle "A" is 138º
angle "B" is verticall opposite to 42º so therefore angle "B" is 42º

a +-21 = -38
help me please
Answer:
A= -17
Step-by-step explanation:
A +-21 = -38
+21 +21
-38+21= -17
A= -17
Answer:
a = -17
Step-by-step explanation:
To solve this, we need to get A alone:
A + -21 = -38
—- +21- +21
Remember, when you do something to one side, you need to do the same thing to the other side.
Now:
A = -17!
To check:
-17 + -21 = -38
Therefore, A = -17

Answer:
300 degrees
Step-by-step explanation:
After converting the given equation 5π/3 into degree, the value obtained will be equal to 300°.
What is an expression?If a mathematical operation includes at least two words that are connected by an operator and either comprise numbers, variables, or both, it is referred to as an expression.
The operations with reflection coefficients include adding, subtracting, multiplying, and dividing. In order to include terms into an expression, a mathematical operation like reduction, addition, multiplication, or division is used.
As per the given information in the question,
5π/3 radians to degree.
To convert radians to degree multiply it with 180/π

Lin opened a lemonade stand during the summer. She
noticed that she sold more lemonade on warmer days.
For each day she sold lemonade, she plotted the point
(t,c), where t represents high temperature and c
represents cups of lemonade sold.
b. A computer program found that the line c= 2t - 89
is a good fit for the data. Use this equation to predict
how many cups of lemonade Lin might sell on a day
when the high temperature is 74 degrees.
c. the high temp this Sunday is expected to be 5 degrees warmer that the high temp this Saturday. using the line c = 2t - 89 how many more cups of lemonade should lin expect to sell on Sunday than Saturday? explain or show your reasoning
Answer:
59 cups ;
10 cups
Step-by-step explanation:
Given that he fitted model :
c = 2t - 89
Where, c = cups of lemonade sold ; t = high temperature
On a day when high temperature is 74 degrees ; cups of lemonade sold
Hence,
c = 2t - 89
c = 2(74) - 89
c = 148 - 89
c = 59 cups
Sunday is expected to be 5 degree warmer than on Saturday :
The number of cups sold on Sunday using the fitted model should be :
Difference in temperature between Saturday and Sunday multiplied by the slope value
Slope value from the model = 2
Temperature difference = 5
Difference in Number of cups :
2 * 5 = 10 cups
Number of lemonade sold on Sunday will be 10 cups more than that sold on Saturday
Answer: 59 cups

A parabola can be drawn given a focus of (3, 1) and a directrix of x = -5. What can
be said about the parabola?
The parabola has a vertex at
O,
Answer:
The statements that can be made about the parabola are;
The parabola opens towards the right
The equation of the parabola is (y - 1)² = 16 × (x + 1)
The parabola has a vertex at (-1, 1)
Step-by-step explanation:
The given focus of the parabola is (3, 1)
The directrix of the parabola, x = -5
Therefore, from the location of the directrix (on the x-axis) and the location of the focus relative to the directrix towards the positive direction of the x-axis relative to the directrix, the parabola opens towards the left of the coordinate chart
The general equation of the focus = (h + p, k)
The general equation of the directrix, x = h - p
Comparing with the values of the focus and the directrix of the given parabola, we have;
(3, 1) = (h + p, k)
-5 = h - p
Therefore, we get;
k = 1
h + p = 3...(1)
h - p = -5...(2)
Adding equation (1) to equation (2) gives;
h + h + p - p = 3 + (-5)
2·h = -2
h = -2/2 = -1
h = -1
From equation (1), we get;
h + p = -1 + p = 3
∴ p = 3 + 1 = 4
p = 4
The vertex of the parabola, (h, k) = (-1, 1)
The equation of the parabola in the form (y - k)² = 4·p·(x - h) is therefore, presented as follows;
The equation of the parabola = (y - 1)² = 4 × 4 × (x - (-1))
(y - 1)² = 16 × (x - (-1))
The equation of the parabola is (y - 1)² = 16 × (x + 1).

Tracy's Pie Shop recently sold 15 pies, of which 3 were blackberry pies. Considering this data, how many of the next 20 pies sold should you expect to be blackberry pies?
Answer: 4
Step-by-step explanation:
We can expect that 4 of the next 20 pies sold will be blackberry pies, based on the proportion of blackberry pies in the recent sample of 15 pies.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
If Tracy's Pie Shop recently sold 15 pies and 3 of them were blackberry pies.
Proportion of blackberry pies = 3/15
Proportion of blackberry pies = 0.2
So, in the recent sample of 15 pies, 20% were blackberry pies.
To estimate how many of the next 20 pies sold should be blackberry pies
Let us assume that the proportion of blackberry pies in the next sample of 20 pies will be similar to the proportion in the recent sample of 15 pies.
Therefore, we can use this proportion to estimate the number of blackberry pies in the next sample of 20 pies:
Number of blackberry pies = 0.2 x 20
Number of blackberry pies = 4
Therefore, we can expect that 4 of the next 20 pies sold will be blackberry pies, based on the proportion of blackberry pies in the recent sample of 15 pies.

Answer:

Step-by-step explanation:
I think that's the area.
Please help with this word problem!
Answer:
a)
x = (158-112) / 1x
or 158-112 / x
b) 112+ 23 /158-23 = x
or if you want x to be the same value as the first part then you could write
112+x / 158-x = 135/135
or revise as an equality
23 ≤ 112 < 158
112 + 23 = 158
112 + x = 158
Step-by-step explanation:
Tailwind speed
x = 158-112 / 2
x = 46/2
x = 23 knots
Speed
x = 112 + 23 / 158-23
x = 135 / 135 m/h = same speed as stated in question.
At a particular time of a day, a-7-m high flagstaff casts a shadow which is 8.2m long. What is the height the building which cast a shadow 20.5m in length that the same moment
Answer:
17.5m
Step-by-step explanation:
We solve using the formula
Height /Shadow
Height of flag staff = 7m
Shadow of flag staff = 8.2 m
Height of the building = x
Shadow of the building = 20.5
= 7/8.2 = x/20.5
Cross Multiply
8.2x = 7 × 20.5
x = 7 × 20.5/8.2
x = 143.5 / 8.2
x = 17.5m
The height of the building is 17.5 m
