Answer:
x = -5
Step-by-step explanation:
Since these two triangles are similar, the ratio between the corresponding lengths of each triangle will be the same.
This means the ratio between one side of each triangle (e.g. AD and DC) will be the same as the ratio between a different side of each triangle (e.g. BE and BC).
So, to create an equation for the sides which contain the unknown 'x', we must first find the ratio between the two sides by using a different set of sides.
On the right side we are given 9 for AD, and 18 for DC.
9/18 = 0.5
This means that the extra length of the larger triangle from the smaller one (AD) is half the length of the smaller triangle (DC). We can use this to make an equation for x:
If AD/DC = 0.5, then BE/EC will also = 0.5
BE = x+23
EC = x+41
Therefore:
[tex]\frac{x+23}{x+41} = 0.5[/tex]
Now we can solve by multiplying both sides by x+41 to eliminate the fraction:
[tex]x+23=0.5(x+41)[/tex]
Now we multiply out the brackets and move the terms to different sides:
[tex]x+23=0.5x+20.5[/tex]
[tex]0.5x = -2.5[/tex]
[tex]x = -5[/tex]
And if we substitute the -5 into the equations:
-5+23 = 18
-5 + 41 = 36
We will see that -5 does indeed give us the same ratio between the lengths:
18/36 = 0.5

b)3.2
c)11.2
d)-3.2
11) What is the opposite of
12)
13)
14)
Answer: (10) 3.2 (11) option 2 (12) option 4
(13) Distributive (14) Associative
Step-by-step explanation:
10) "Absolute value" makes the number positive.
- |-4| + |-7.2|
= - 4 + 7.2
= 3.2
11) "Opposite" changes the sign.
the opposite of [tex]-\sqrt{\dfrac{2}{5}}[/tex] is [tex]+\sqrt{\dfrac{2}{5}}[/tex]
12) Reciprocal means "flip" the fraction
the reciprocal of [tex]-\sqrt{\dfrac{2}{5}}[/tex] is [tex]-\sqrt{\dfrac{5}{2}}[/tex]
13) a(b + c) = ab + ac is the Distributive Property
[tex]-\sqrt5(2+X)[/tex]
= [tex]-\sqrt5(2) -\sqrt5(X)[/tex]
= [tex]-2\sqrt5 -X\sqrt5[/tex]
14) a · (b · c) = (a · b) · c is the Associative Property
[tex]20(4\sqrt5)[/tex]
= [tex](20\cdot 4)\sqrt5[/tex]
The red lines on the diagram show the layout for a running event. Runners will race around the triangle-shaped grassy area. What is the total length of the race course? what is The total distance in km.
Answer:
Total distance = 5.754 km
Step-by-step explanation:
Red lines of the right triangle show the layout of the race course.
Total length of the race course = Perimeter of the triangle
Perimeter of the triangle = Sum of the measures of all three sides
= 1.83 + 1.524 + 2.4
= 5.754 km
Therefore, total distance of the race course is 5.754 km.
Answer:
5.754

Find the distance between the two points in simplest radical form.
(8, – 7) and (1, -1)
Answer:
The distance between the two points is [tex]\sqrt{85}[/tex] units
Step-by-step explanation:
Let us revise the rule of the distance between two point [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex]
[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
∵ We need to find the distance between the two points (8, -7) and (1, -1)
→ Let [tex]x_{1}[/tex] = 8 and [tex]x_{2}[/tex] = 1
→ Let [tex]y_{1}[/tex] = -7 and [tex]y_{2}[/tex] = -1
→ Substitute their values in the rule above
∴ [tex]d=\sqrt{(1-8)^{2}+(-1--7)^{2}}[/tex]
∴ [tex]d=\sqrt{(-7)^{2}+(-1+7)^{2}}[/tex]
∴ [tex]d=\sqrt{49+36}[/tex]
∴ [tex]d=\sqrt{85}[/tex]
→ Simplify the radical
∵ 85 = 5 × 17
→ Both of them are prime numbers
∴ The simplest form of [tex]\sqrt{85}[/tex] is [tex]\sqrt{85}[/tex]
∴ The distance between the two points is [tex]\sqrt{85}[/tex] units

Label each of the following as true, false, or open.
a. –4(5x) = 12
b. 4 x 6 = 24
c. a + 4 = 6, when a = 2.
d. 4x = 19, when x equals 5.
Answer:
a. –4(5x) = 12; OPEN
b. 4 x 6 = 24; TRUE
c. a + 4 = 6, when a = 2; TRUE
d. 4x = 19, when x equals 5; FALSE
Step-by-step explanation:
a. –4(5x) = 12 [-20x = 12 {Divide -20 from both sides} x = -0.6 So, if x is = -0.6, then it is true, so OPEN.
b. 4 x 6 = 24 [4 x 6 = 24 so TRUE]
c. a + 4 = 6, when a = 2. (Plug 2 in for a) 2 + 4 = 6; 6 = 6; TRUE
d. 4x = 19, when x equals 5. (Plug 5 in for x) 4(5) = 19; 20 is not = 19; FALSE
simplify for this. 22 + (3x3 - 4x4)
Answer:15
Step-by-step explanation: 1st multiple what’s in the parenthesis (3*3= 9 & 4*4= 16
Next write it out 22+(9-16)
Then you subtract 9 from 16 since it’s in parenthesis So it’s 22+(-7) and since you are adding a negative and a positive together you will have to subtract and keep the sign of the larger number so the answer is 15 since u needed to subtract but 22 is the larger number making it positive answer

Find the area of triangle DEF with vertices D(-1,2), E(3,-2) and F(-2,-2).*
Answer:
The area of the triangle DEF is 10.
Step-by-step explanation:
Area of a Triangle:
A triangle of base B and height H (both must be perpendicular) has an area of:
[tex]\displaystyle A=\frac{BH}{2}[/tex]
The image below shows the triangle formed by the points DEF. It's important to notice the points E and F lie on the same horizontal line because they both have the same y-coordinate.
This fact simplifies the calculations since we can easily compute the length the of base as the difference of their x-coordinates:
B=3-(-2)=3+2=5
Being the base of a horizontal line, the height of the triangle can be calculated as the difference of y-coordinates of D and the height of that line.
H=2-(-2)=4
With these two values, we calculate the area:
[tex]\displaystyle A=\frac{5*4}{2}=10[/tex]
The area of the triangle DEF is 10.

The bus routes in a city run on average every 15 minutes. The route times can vary by three minutes. Which absolute value equation can be used to find the maximum and minimum wait times at a bus stop?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Let absolute variation in the wait time at the bus stop = v
Variation = ±3 minutes
Average bus run through the city = 15 minutes
Hence, the minimum and maximum run values due to the variation can be modeled as:
|variation - average run| = ±3
|v - 15| = ±3
minimum : v = - 3 +. 15 = 12 minutes
Maximum : v = 3 + 15 = 18 minutes

Complete Question
You are measuring walnuts for banana-walnut oatmeal and a spinach and walnut salad. You need 3/4 cup of walnuts for the oatmeal and 7/8 cup of walnuts for the salad. You have a 1/8 -cup scoop. Complete the descriptions of two different ways to find how many scoops of walnuts you will need. Enter all non-whole number answers as mixed numbers in simplest form.
Answer:
13 scoops
Step-by-step explanation:
Description 1
Step 1
3/4 cup of walnuts for the oatmeal
7/8 cup of walnuts for the salad
Total cups of walnuts needed for both salad and oatmeal =
3/4 cups + 7/8 cups
(3/4 + 7/8)
(6 + 7/8)
= 13/8 cups of walnuts
= 1 5/8 cups of walnuts
Step 2
You have a 1/8 -cup scoop
The number of cup scoops of walnuts need is calculated as
1 5/8 cups ÷ 1/8 cup scoop
= 13/8 ÷ 1/8
= 13/8 × 8/1
= 13 scoops
Therefore, 13 scoops of walnuts is needed.
Description 2
3/4 cup of walnuts for the oatmeal
7/8 cup of walnuts for the salad
1/8 cup scoop
Therefore,
(3/4 + 7/8) ÷ 1/8
=(13/8) ÷ 1/8
= 13 scoops of walnuts are needed

Step 3: Simplify 18 + 12 to 30.
-5z = 30
Step 4: Divide both sides by -5.
z = [tex]-\frac{30}{5}[/tex]
Step 5: Simplify [tex]\frac{30}{5}[/tex] to 6.
z = -6

A survey o 100 people found that 35 people exercise in the morning, 45 people exercise in the afternoon, and 20 people exercise at at night. Tara claims that 33:55, 48:88 and 20:65 are possible ratios from this data. Jim claims that 35:100, 405:100 and 200:100 are possible ratios from the data who is correct? Explain
Answer:
Jim is correct.
Step-by-step explanation:
Given that:
Total people = 100
People who exercise in morning = 35
People who exercise in the afternoon= 45
People who exercise in the evening = 20
Ratio claimed by Tara = 33:55, 48:88, and 20:65
Ratio claimed by Jim = 35:100, 45:100, and 20:100
To find:
who is correct ?
Solution:
Looking at the ratio claimed by Tara, the ratio are number which are not known to us.
Therefore, the ratio claimed by Tara can not be correct.
Now, looking at the ratio claimed by Jim:
35:100, 45:100, and 20:100
35 is the number of people who exercise in morning.
45 is the number of people who exercise in evening.
20 is the number of people who exercise in night.
and 100 is the total number of people.
Therefore, this ratio represents the "Part-to-whole" ratio.
So, Jim is correct.
