Step-by-step explanation:
Step 1: Recognizing that we have an isosceles triangle
This is an isosceles triangle because it has two congruent sides(two sides with a length of 7). The angles across from the congruent sides are also congruent, so the angle without a label measures x∘
x, degrees:
Hint #22 / 4
Step 2: Writing an equation
The three angles in a triangle add up to 180 180 ∘
180, degrees. We can write this as an equation:
x + x + 80 = 180∘
+x ∘
+80 ∘
=180 ∘
x, degrees, plus, x, degrees, plus, 80, degrees, equals, 180, degrees
Hint #33 / 4
Step 3: Solving for x
x+x+80
2x+80
2x+80−80
2x

=180
=180 Simplify the left-hand side
=180−80 Subtract 80 from each side
=100
=

Divide each side by 2
=50
Hint #44 / 4
The answer
x = 50

[tex]~~~\text{Area of triangle} = \dfrac 12 \times \text{Base} \times \text{Height}\\\\\implies 10 = \dfrac 12 \times 5 \times w\\\\\implies w =\dfrac{20}5 \\\\\implies w = 4 ~cm[/tex]
Answer:
4cm
Step-by-step explanation:
» Concepts
The area of a triangle is how much space is in the triangle. The formula for the area of a triangle is [tex]\frac{1}{2} bh[/tex], where b = base and h = height.
» Application
We're given the area as 10 cm² and the base as 5 cm. Thus, we have to plug these values into the formula to solve for the height.

A mirror frame in the shape of an oval is shown below. The ends of the frame form semicircles:
An oval is formed by a rectangle with semicircles at each end. The length of the rectangle is 54 inches. The width of the rectangle is 27 inches.
Which of the following is the perimeter of the inner edge of the frame?
(π = 3.14)
Answer:
4578.12 inches squared
Step-by-step explanation:
so 54 x 27 x 3.14 for pie equals 4578.12 that's the awnser but put it in inches squared ok so 4578.12 inches squared

Answer:
91.1250 m^3
Step-by-step explanation:
The volume of a cube can be calculated if you know its side length. The formula is then volume cube = side3. This is simply the length of the side multiplied by itself two times.
Answer:
91.125
Step-by-step explanation:
The formula to find the volume of a cube is lwh. All the side lengths of a cube are equal. So in this case, 4.5 to the third power is 91.125.

Answer:
∠G, ∠HGI, ∠IGH
Step-by-step explanation:
» Concepts
To name an angle, you MUST include the vertex either in the middle or have it standing by itself. To clarify, you can either call this angle ∠G, ∠HGI, or ∠IGH because they all include the vertex, G, in the middle or by itself. You put ∠HIG, which is incorrect because the vertex is not I.

(Find the Probability Question)
Choose 2 girls from a class of 12 boys and 8 girls.
Step-by-step explanation:
what should be the question ?
how many different pairs of 2 girls can you pick out of 8 ?
what is the probability that a specific girl is in the picked pair ?
or is it : if you pick randomly 2 students from the class, what is the probability to have picked 2 girls ?
and there are more options.
but I assume the problem is the picking randomly 2 students.
so, it is 20 students (12 + 8). if we pick 1 student, we have a chance of 12/20 = 3/5 to pick a boy, and a chance of 8/20 = 2/5 to pick a girl.
in our experiment we pick 2 students in a row without returning the first pick into the main pool.
the probabilty for the first pick to be a girl is, as mentioned, 2/5 or 0.4.
for the second pick we have only 7 out of 19 choices to pick a girl. so, the probability to pick a girl now is 7/19.
the combination of both (non-overlapping) probabilities is done via multiplication, and the probabilty to pick 2 girls is :
2/5 × 7/19 = 2×7 / 5×19 = 14/95 = 0.147368421...

5) Solve for x and find both angle measurements -
Answer:
x = 30
(2x)° = 60°
x = 30°
Step-by-step explanation:
The two angles combined is a right angle, and a right angle is 90°, so we can put that into this equation:
2x + x = 90 which is the same as 3x = 90 because 2x + x = 3x
3x = 90
divide both sides by 3 so you can get x by itself
3x divided by 3 = x
90 divided by 3 = 30
you get x = 30
since x = 30, 2x is the same as 2 times 30, and that is 60.

B. Andrew is correct because the 5 in the hundredths place is equal to 5.
C. Andrew is correct because the 4 to the right of the hundredths place is less than 5.
D. Paul is correct because the 5 in the hundredths place is equal to 5.

Answer:
The mean absolute deviation is 4
Step-by-step explanation:
The mean absolute deviation is a measure of how much a data set varies.
Step 1: Compute the mean
mean = the sum of all the terms / number of terms
mean = 94 + 86 + 95 + 99 + 88 + 90 / 6
= 552 / 6
= 92
The mean is 92
Step 2: Finding the absolute deviation
You would take each number in the data set and subtract it from the mean, take the absolute value. After you take the sum of the absolute data values
|data set #1 - mean| + |data set #2 - mean| + ... + |data set #6 - mean|
= |94 - 92| + |86 - 92| + |95 - 92| + |99 - 92| + |88 - 92| + |90 - 92|
= |2| + |- 6| + |3| + |7| + |- 4| + |- 2|
= 2 + 6 + 3 + 7 + 4 + 2
= 24
To find the mean absolute deviation you divided the sum by total number of terms...
24/6 = 4
The average (mean) is equal to the sum of all the data values divided by the count of values in the data set (which was step 1)

Which Measure of center best represents the set of data? calculate the measure of center. number of television sets in the whole: 4, 4, 3, 4, 4, 1, 3, 4, 2, 4
The question is worded weirdly, but the mean (average) is 3.3. The median is 4. The median would probably represent this better.
Step-by-step explanation:
The median is found by adding all of the numbers in the data set and then dividing by how many numbers there are.
The median is the middle number, which you find by alternately crossing out the biggest and smallest numbers.
Hope this helps!
In the diagram of an apartment, each inch represents 6 feet. Which is the area of the apartment's balcony?
Answer:
72 square feet
Step-by-step explanation:
Since you already know the 2 inches, you just need to find out the other side, and by subtracting the longer side 6 inches, to the shorter side on the furthest side 5 inches, you get 1 inch. And since each inch represents 6 feet, the final equation would be 12 (2x6) x 6 (1x6). So the answer would be 72 square feet.

What is the value represented by the letter A on the box plot of data?
5, 20, 40, 50, 50, 85
Answer:
The value represented by the letter A on the box plot of data is 5
Step-by-step explanation:
The set of data is
{5, 20, 40, 50, 50, 85}
In the given box plot,
A = Minimum value
B = First quartile
C = Median
D = Third quartile
E = Maximum value
Since the minimum value of the set is 5, therefore the value represented by the letter A on the box plot of data is 5.
