Answer:
B. 29º
Step-by-step explanation:
Given that BCDE is a parallelogram, then [tex]BE \parallel CD[/tex] and A, E and D are collinear. Then, angle E inside triangle ABE and angle D inside parallelogram BCDE have the same measure. That is:
[tex]\angle D = \angle E = 51^{\circ}[/tex] (1)
In addition, the sum of internal angles in triangles equals 180º, which implies that:
[tex]\angle A + \angle B + \angle E = 180^{\circ}[/tex] (2)
If we know that [tex]\angle B = 100^{\circ}[/tex] and [tex]\angle E = 51^{\circ}[/tex], then [tex]\angle A[/tex] is:
[tex]\angle A = 180^{\circ}-\angle B - \angle E[/tex]
[tex]\angle A = 180^{\circ}-100^{\circ}-51^{\circ}[/tex]
[tex]\angle A = 29^{\circ}[/tex]
Hence, correct answer is B.
Answer:
The answer would be be 29 degrees
Step-by-step explanation:

How many quarts are in 10 cups
Answer:
There's 2.5
Step-by-step explanation:
4 cups is equal to 1 quart
So that means 8 cups is equal to 2 quarts

This means that 10 cups is 2.5 quarts.
Answer:
2.5 quarts
Step-by-step explanation:
since there are 0.25 quarts in one cup. you have to multiply 2.5 by 10. hope this helps*

Max completed 140 questions on DFM last week.
This week, Max completed 182 questions.
Find the percentage increase.
Answer:
30%
Step-by-step explanation:
182-140=42(increase)
increase ÷ original × 100 %
= 42÷140×100%
=30%
The percentage increase from the old number to new number is 30 percent.
Given that, Max completed 140 questions on DFM last week. This week, Max completed 182 questions.
We know that, percentage increase = (New Number - Original Number)/Original Number ×100
= (182-140)/140 ×100
= 42/140 ×100
= 4200/140
= 30%
Therefore, the percentage increase is 30 percent.

The shape congruent to given figure is Figure 4.
Option D is correct.
What is congruency?Congruent figures have sides that are the same length and angles that are the same measurement. In other terms, two figures are said to be congruent when they are superimposed upon one another. Even when they are flipped or rotated, they perfectly fit on top of one another.
We have a figure which is similar to parallelogram.
First, figure is seems to be rectangle and do not have same unit measurement which is not Congruent.
Now, the second has more width than given figure.
Now, Third figure is also a rectangle and cannot be congruent.

Find the missing length
Answer: 15
Step-by-step explanation:
For this you will have to use pythagoras’ theorem.
The formula for the shorter side of this triangle is u²=c²-b² (or in this case u²=17²-8²).
17²=289
8²=64
The formula becomes u²=289-64 or u²=225
Then to find u on its own you have to square root 225.
The square root of 225 is 15.

John wants to gain weight for his wrestling team so he can compete in a different weight class. He currently weighs 187 pounds, and is gaining weight at a rate of 1.5 pounds per week. Which equation below models this situation * number of weeks y = total weight (pounds )
Answer:
The equation would be 1.5w + 187 = y.
Step-by-step explanation:
1.5 lbs per week
already 187
The variable would be 'w'
so 1.5w +187 = y

Graph the image of the figure using the transformation given.
(its multiple choice!)
The original image undergoes reflection across x=-3.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
In the given graph DEFG is the original image.
D'E'F'G' is the new image after the transformations applied.
A reflection is defined by the axis of symmetry or mirror line. In the above diagram, the mirror line is x = -3.
Under reflection, the shape and size of an image is exactly the same as the original figure.
This type of transformation is called isometric transformation.
Hence, the original image undergoes reflection across x=-3.

Vivian needs to ride her bike to her friend’s house 96 miles away. She is riding at an average speed of 15 miles per hour. She has 6 hours to get there. Will she make it?
Answer:
No.
Step-by-step explanation:
If she is riding 15 miles per hour (the rate), and she has six hours (the time), then in order to find out the distance, we multiply the rate*the time.
15*6 = 90
90<96
So, no, she will not make it.
Isabella deposited $500 into a savings account at a local bank that earned 5% interest per year. How much interest does she earn in her first year?
Answer:
$25
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
putting time into years for simplicity,
12 months ÷ 12 months/year = 1 years,
then, solving our equation
I = 500 × 0.05 × 1 = 25
I = $ 25.00
The simple interest accumulated
on a principal of $ 500.00
at a rate of 5% per year
for 1 years (12 months) is $ 25.00.

Donald's Earnings, x (dollars) Fallons Earnings, y 38 45 43 50 48 55 53 60 58 65 Which equation best represents Fallon's earnings in terms of Donald's earnings? A. y=x+7 B. X=7y C. y=7x D. x=y+7
Given:
The table of values for Fallon's earnings in terms of Donald's earnings.
To find:
The equation that best represents Fallon's earnings in terms of Donald's earnings.
Solution:
In the given table the x-values are increasing by 5 units and y values increasing by 5 units. It means the rate of change of y with respect to x is constant and the table represents a linear function.
If the graph of a linear function passes through two points, then the equation of linear function is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Consider any two points from the table. Let the two points are (38,45) and (43, 50). Then, the equation is
[tex]y-45=\dfrac{50-45}{43-38}(x-38)[/tex]
[tex]y-45=\dfrac{5}{5}(x-38)[/tex]
[tex]y-45=1(x-38)[/tex]
[tex]y-45=x-38[/tex]
Adding 45 on both sides, we get
[tex]y=x-38+45[/tex]
[tex]y=x+7[/tex]
Therefore, the correct option is A.

Work out the probability that Ria takes one counter of each colour.
You must show your working.
Please show the full working out so I know how to get full marks in future I’ll give brainiest
Answer:
7/18
Step-by-step explanation:
Probability is the ratio of the number of possible outcomes to the number of total outcomes.
Given that there are 9 counters in a bag, 7 are green while 2 are blue.
the probability of picking at random a
Green counter = 7/9
Blue counter = 2/9
The probability that Ria takes one counter of each colour if 2 counter are picked as random is Green and Blue or Blue and Green
This is
=7/9 * 2/8 + 2/9 * 7/8
Recall that when a counter is picked the number of that ball available reduces and so does the total number of counter
=14/72 + 14/72
= 28/72
= 7/18
