Answer:
measure of angle E is 45 degrees because if you look closely then it is a
45, 45, 90 triangle, and so e is 45 degrees
Measure of c = 360-45+79+134 = 102 degrees
Step-by-step explanation:
The measures are 1) ∠ C = 101°, 2) ∠ Q = 89°, 3) ∠ M = 97°, 4) ∠ W = 34°, 5) x = 4 and 6) x = 13
What is trapezoid?A trapezoid, also known as a trapezium, is a flat-closed shape having 4 straight sides, with one pair of parallel sides. The parallel sides of a trapezium are known as the bases, and its non-parallel sides are called legs.
Given that, the quadrilateral in the figure is a trapezoid, we need to find the asked measures,
We know that, trapezoids are having one pair of opposite side parallel, therefore, adjacent angles are supplementary,
1) ∠ C + ∠ F = 180°
∠ C = 180°-79° = 101°
2) ∠ T + ∠ Q = 180°
∠ Q = 180°-91°
∠ Q = 89°
3) JKLM is an isosceles trapezoid, therefore, opposite angle are supplementary,
∠ M + ∠ K = 180°
∠ M = 180°-83°
∠ M = 97°
4) WXYZ is an isosceles trapezoid, therefore, opposite angle are supplementary,
∠ Y + ∠ W = 180°
∠ W = 180°-146°
∠ W = 34°
5) ∠ S + ∠ V = 180°
14x-15 + 139 = 180
14x = 180-124
x = 4
6) ∠ A + ∠ B = 180°
9x+2+5x-4 = 180
14x-2 = 180
14x = 182
x = 13
Hence, the measures are 1) ∠ C = 101°, 2) ∠ Q = 89°, 3) ∠ M = 97°, 4) ∠ W = 34°, 5) x = 4 and 6) x = 13

5. In 2 concentric circles, the inner radius is 2 cm and the outer radius is 4 cm.
What is the area between the two circles? (Use
[tex]\pi \\ [/tex]
= 3.14)
Answers
Step-by-step explanation:
The area of circle with radius 4cm is,
area of circle = π r *r = 3.14 * 4 * 4
= approx 50.27
The area of circle with radius 2cm is,
area of circle = π * r * r = 3.14 * 2 * 2
= approx 12.57
The circles are concentric means they have a common Centre, so,
Area between the two circles = area of bigger circle - area of smaller circle
= 50.27 - 12.57
= 37. 7 sq. cm

The researchers cautioned that the findings should not be a cause for alarm because the differences were found to be small. Explain how the difference between the math and reading score for the child care group and the overall mean for third graders could be small but the researchers could still reach the conclusion that the mean for the child care group is significantly higher than the overall mean.

Find the value of x.
Answers
Answer:
x = 62°
Step-by-step explanation:
the top-most angle in the top isosceles triangle must be 73° also
the third angle of the top isosceles triangle is (180 - 73 + 73) which is 34°
the left portion of the right angle must be 56°
you can find by using this equation: x + x + 56 = 180
2x = 124
x = 62
The numerator of the given fraction is 4 less than the denominator. If 5 is added to both numerator and denominator, the resulting fraction is equivalent to 5/7 . What is the original fraction? heeeeeeelp!!!
Answers
Answer:
5/9
Step-by-step explanation:
Let the denominator be k and thus numerator be 4 less than k or k - 4.
Fraction = (k - 4)/k
If 5 is added to both:
=> (k-4 + 5)/(k + 5) = 5/7
=> 7(k + 1) = 5(k + 5)
=> 7k + 7 = 5k + 25
=> 2k = 18
=> k = 9
Thus,
Fraction is (k-4)/k = (9-4)/9 = 5/9

Answers
Answer:
1. D= 46 degrees
2. X= 50 degrees
3. X= 180-118 = 62 degrees
4. X = 90-75 = 15 degrees.
Step-by-step explanation:
Answer:
Going by the order from the first row left to right and then second row left to right
1) D=46
2) x=62
3) x=50
4) x=15
5) b=40
Step-by-step explanation:
So for the first column for the first question its a complementary angle which means 2 or more angles added up to from a 90 degrees angle. We got 44 degrees already and an unknown angle which will lead to 90-44= 46 and that 46 degrees is your answer. D will be equal to 46.
For the second question on the first column, you have 2 angles forming a straight line. This is a s upplementary angle which means 2 or more angles added up to from 180 degrees. You have 1 angle already which is 118 and to find the other angle, 180-118 which will be 62. X will equal to 62
For the thrid question which is the first question on the SECOND column, you have another supplementary angle. You have 130 and 180-130=50 and X will equal to 50.
For the 4th question you have a complementary and one angle is 75. You do 90-75 and get 15. X will equal to 15.
The last question which is the huge rectangle on the right, you have 2 intersecting lines. We know one side is 40. Well the only thing that makes sense here is B=40 since its vertical to the one angle given. Vertical angles are equal so therfore the answer is b=40

Write a quadratic function whose zeros are 12 and 2 .
Answers
Answer:
The quadratic function is: [tex](x-2)(x-12)=0[/tex] and can be written as: [tex]x^2-14x+24=0[/tex]
Step-by-step explanation:
A quadratic function can typically be written in multiple forms, among which includes: (x-a)*(x-b)=0 where a, b can be any number
This quadratic function is solved for a and b, which represents the zeroes (or can be called roots) of the equation.
Given that the zeroes are already given, all that's need to write the quadratic function is to substitute a and b with the given zeroes:
Note: It doesn't matter which zeroes are substituted for a and b
(x-a)*(x-b)=0
(x-2)*(x-12)=0
Now, we can leave it in this form or expand the equation (often called the FOIL method):
(x-2)*(x-12)=0 Multiply each term with the other terms
[tex]x^2-2x-12x+24=0[/tex] Simplify by combining like terms
[tex]x^2-14x+24=0[/tex]
Thus, the quadratic function for zeroes 12 and 2 is: [tex]x^2-14x+24=0[/tex]

Scatter plot is the plot of graph in which the values of two variables plotted using their coordinates on the graph.
The average rate of change is the ratio of change in y values to the change in x values of the scatter plot.

Find the area of triangle ABC and the area of XYZ. AABC - AXYZ.
Answers
Answer:
ABC= 60 XYZ=540
Step-by-step explanation:
The area of a triangle is 1/2*base*height so for ABC we need to find the height first. To do this we use pythag theorem, and create the equation 13^2=5^2+height^2 rearranging this we can figure out that sqrt(height)=13^2-5^2. For the base we do 2*5 since there are two congruent line segments both equal to 5. Using this we can do 1/2*12*10=area of ABC
For XYZ we can do 1/2*30*36=area of XYZ, we can do 2*15 since there are 2 congruent 15 length line segments at the base.

Answers
Answer:
0.205 ; 0.117 ; 0.999
Step-by-step explanation:
Using binomial probability distribution :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Probability of success, p = 0.5
P(x = 4) = 10C4 * 0.5^4 * 0.5^6
P(X = 4) = 0.205078125
B.) 3 heads and 7 tails
P(X = 7) = 10C7 * 0.5^7 * 0.5^3
P(X = 7) = 120 * 0.0009765625
P(X = 7) = 0.117
P(atleast one head)
P(x greater than equal to 1) = p(x =1) +... P(x = 10)
Using a binomial probability calculator :
P(x greater than equal to 1) = 0.999
The price of a calculator is increased by 99 % and now is $ 883.56 . Find the original price.
Answers
Answer:
$444
Step-by-step explanation:
1.99 * x = 883.56 [The price has increased by 99%, so you multiply it by 1 + 0.99]
x = 444
Answer:
The original price of the calculator was $444
Step-by-step explanation:
So follow this equation
1.99x=883.56
1.99 becuase 99 percent is the .99 and since the original price with no change of all is worth 100 percent With no sales or increases, we add the 99 percent this time becuase it increased by 99%.
X is for the original price of the calculator
If you still don’t undertsand it works like this.
100% is basically 1.00 becuase you move the decimal place 2 times to the left for percentages. And if you multiply the original price by 100 percent, its basically 1x which will end up with x. Same thing. But when you increase a price, you add to the 1.00 like in this case 99% increase which is adding .99 to 1.00. If it decreases same thing except you subtract from that 1.00 But the percent. this saves a whole nother step Which makes percentage questions liek these much quicker and easier.
Alright so the eqaution is 1.99x=883.56
Solve by isolating x by dividing 1.99 on both sides
You’d get 444=x
$444 is the original price
