Find the perimeter and area of the shape based on the information provided.
Answer:
Area of the shape=241.2cm^2
Perimeter of the shape=76.08cm
Step-by-step explanation:
Find the base for the first triangle = tan(75°)=O/A
= A=30/tan(75°)
=A = 8.04cm (2decimal place)
Area of first triangle= 1/2×Base×height
=1/2×8.04cm×30cm
=120.6cm^2
So total area for the shape is = 2×120.6cm^2
=241.2cm^2
Perimeter of the shape = 2(30cm+8.04cm)
=76.08cm
I need you to solve for X
Answer:
x=5.3
Solving:
6*x, 4*8
these are both 90 degree angles, but what is the solution for x?
8*4=32 solving the area, so we need to get the same thing for the other
32 divided by 6 equals 5.333 repeating
Nearest tenth huh?
5.3
so X=5.3

A contractor is roofing a house. The contractor considers a roof to be steep when the roof rises 5 in., or more, for every
12 in, it runs. The following graph is a model of how steep the roof is. Does the contractor believe the roof is steep, and
what is the slope of the roof?
Using the slope, it is found that the correct option is:
No, the contractor does not believe the roof is steep because the slope is 0.
Given two points, [tex](x_0, y_0)[/tex] and [tex](x_1, y_1)[/tex], the slope is given by change in y divided by change in x, that is:
[tex]m = \frac{\Delta_y}{\Delta_x} = \frac{y_1 - y_0}{x_1 - x_0}[/tex]
The slope measures the inclination of a graph, and if it is zero, the graph is not steep.In this problem, y is always the same value, hence [tex]\Delta_y = 0[/tex] and [tex]m = 0[/tex], which means that the roof is not steep, and the correct option is:
No, the contractor does not believe the roof is steep because the slope is 0.

The value of y is directly proportional to the value of x. If y = 25 when x = 120, what is the value of y when x = 72?
Step-by-step explanation:
y directly proportional to X
y=kx
when k is constant
y is 25 and X is 120
25=k120
divide both sides by 120
25/120
k=25/120
there fore the law connecting is 25/120
what is the value of y when x = 72? 25/120*72=3
therefore y is 3

Answer:
110° = ∠AED
Step-by-step explanation:
Four sides polygon. The sum of the angles = (n - 2)180; 4 - 2(180) = 360°
∠B + ∠D + ∠BCD + ∠DEB = 360°
92° + 98° + 86° + ∠DEB = 360°
276° + ∠DEB = 360°
∠DEB = 360° - 276°
∠DEB = 84°
Now ∠AEB + ∠BED + ∠AED = 360° All exterior angles of any polygon = 360°
166° + 84° + ∠AED = 360°
250° + ∠AED = 360°
110° = ∠AED

Part A: How much of a markdown did her friend give Sheila?
Part B: What was the percent markdown, rounded to the nearest whole percent?
Answer:
$15
I don't know the percentage.
Step-by-step explanation:
50 + 50 = 100, 2 + 2 = 4, .50 + .50 = 1
100 + 4 = 104 + 1 = 105
100 - 90 = 10 plus the 5 left-over = 15
This list shows the quantity of items purchased by customers at a particular checkout counter of a supermarket. 13, 6, 5, 9, 12, 14, 18, 4, 13, 12, 4, 3, 11, 14 Create a histogram that correctly displays the data.
Histograms are used to represent data using bars
The dataset is given as:
3, 6, 5, 9, 12, 14, 18, 4, 13, 12, 4, 3, 11, 14
Rearrange in ascending order
3, 3, 4, 4, 5, 6, 9, 11, 12, 12, 13, 14, 14, 18
Calculate the range
[tex]\mathbf{Range = 18 - 3}[/tex]
[tex]\mathbf{Range = 15}[/tex]
Using 4 classes, the class width is
[tex]\mathbf{Width = \frac{Range } 4}[/tex]
[tex]\mathbf{Width = \frac{15} 4}[/tex]
[tex]\mathbf{Width = 3.75}[/tex]
Approximate
[tex]\mathbf{Width = 4}[/tex]
So, we have the following frequency table

Bridget, Brian & Caroline share some money in the ratio 4 : 9 : 4.In total, Bridget and Caroline receive £48.How much does Brian get?
Answer:
£54
Step-by-step explanation:
According to the ratio:
Bridget = 4/17
Brian = 9/17
Caroline = 4/17
____
So if Bridget and Caroline receive £48, that would mean £48 is 8/17 of the total amount. We can find 1/17 of the money by dividing £48 by 8.
48 / 8 = 6
And then multiply that by 9 to find 9/17 of the money (the amount Brian has).
6 x 9 = 54

3y + 15 = 2x + 15 =
Answer:
x = 3/2y
y = 2/3x
Step-by-step explanation:
x = 3/2y
Swap sides so that all variable terms are on the left hand side
2x + 15 = 3y + 15
Subtract 15 from both sides
2x = 3y + 15 - 15
Subtract 15 from 15 to get 0
2x = 3y
Divide both sides by 2
2x/2= 3y/2
Dividing by 2 undoes the multiplication by 2
X = 3y/2
Y = 2/3x
Subtract 15 from both sides
3y = 2x + 15 - 15
Subtract 15 from 15 to get 0
3y = 2x
Divide both sides by 3
3/3y = 2/3x
Dividing by 3 undoes the multiplication by 3
y = 2/3x

a. 2/3
Step-by-step explanation:
The bar over the 6 means the digit is repeated indefinitely. A bit of algebra can turn a repeating decimal into a fraction. Let x represent the value of the repeating decimal.
[tex]x=0.6\overline{6}\\\\10x=6.6\overline{6}\\\\10x-x=6.6\overline{6}-0.6\overline{6}\\\\9x=6\\\\x=\dfrac{6}{9}=\boxed{\dfrac{2}{3}}[/tex]

The attachment shows the long division of 2/3 gives a repeating decimal with a repeating digit of 6. You can tell the quotient repeats when the new dividend (after subtraction) is equal to a dividend you have seen before. In this case, the dividend is repeatedly 20, and the quotient digit is repeatedly 6.
The point of the long division is to show you that 2/3 is the correct answer choice for a rational number equivalent to 0.666...(repeating).

Which pair of triangles must be similar?
A.Triangles 1 and 2 are equilateral.
B.Triangles 3 and 4 each have an 80 degree angle.
C.Triangle 5 has a 80 degree angle and a 30 degree angle, and Triangle 7 has a 70
degree angle
D.Triangle 7 has 2 50 degree angle, and Triangle 8 has a 50 degree angle and a 100
degree angle
Answer:
Step-by-step explanation:
This question involves the concept of similar triangles.
The pair of triangles that are similar are "B and D".
A pair of triangles is termed as similar triangles if the two angles of both the triangles are equal to each other. Hence, we will check this condition for each pair given in the question.
A.
Only one angle is given to be equal for both the triangles, while the other two angles are unknown. Hence, this pair can not be termed as similar.
B.
For an isoceles triangle, two sides and two angles of the triangle are equal. Considering the 40° angle to be the equal angle, we can safely conclude that the two angles of both the triangles in the pair are the same. Hence, this pair can be termed as similar.
C.
Triangle 5 has angles: 30°, 90° and (180°-30°-90°) = 60°. While triangle 6 has angles: 30°, 70°, and (180°-70°-30°) = 80°. Since all the angles of both the triangles are different. Therefore, they can not be termed as similar.
D.
Triangle 7 has angles: 50°, 20° and (180°-50°-25°) = 105°. While triangle 6 has angles: 50°, 105°, and (180°-50°-105°) = 25°. Since all the angles of both the triangles are equal. Therefore, they can be termed as similar.
Roberto works in a home appliance store she is paid $195 per week and 3% on all sales over $1000 during one year her average weekly sales were $7800 about how much did she earned weekly? about how much did she earned during the year?
Step-by-step explanation:
she gets $195 per week plus 3% on sale OVER $1000.
ok. so, her weekly sales were $7800.
that means we need to calculate 3% of ... $6800 !
as she gets the commission only on sales that are over $1000.
6800 = 100%
1% = 100%/100 = 6800/100 = 68
3% = 1%×3 = 68×3 = $204
so, she earned $195 + $204 = $399 per week
and as there are 52 weeks per year, she then earned
399×52 = $20,748 per year.
