Answer:
28
Step-by-step explanation:
From what I can see in the photo, it says one side is 2x+5 and the other is 5x + 2. All side lengths in a rhombus are equal, so we know that:
2x+5 = 5x+2
3 = 3x
1 = x
So one side length is 7. With all four sides, you get 4 * 7 = 28

Red=40%
Green =x%
40/100 × 60apples
0.4×60
24red apples
so 60-24
36green apples
Answer:
b) 36.
Step-by-step explanation:
Justicemoya35 has an excellent answer, but I will provide a slightly different approach!
According to the word problem, the box contains 60 apples.
If 40% of the apples are red, then 60% of the apples are green.
As I mentioned before, there are 60 apples; 60% of the 60 apples are green.
This means we have the find 60% of 60.
We can find the percentage of a number by using this formula:
60% OF 60
[tex]\frac{is}{of} =\frac{percent}{100}[/tex]
[tex]\frac{x}{60} =\frac{60}{100}[/tex]
Now that I've correctly set up the problem, we cross multiply, then divide the products.
[tex]60*60=3600[/tex]
[tex]100*x=100x[/tex]
[tex]3600/100x=36[/tex]
[tex]x=36.[/tex]
Therefore, 36 apples are red.
If AABC ~ ADEF, what is the length of DE?
NEED HELP ASAP please and thanks In advance
Answers
Answer:
DE = 21
Step-by-step explanation:
Recall: the ratio of the corresponding side lengths of similar triangles are equal
Given that ∆ABC ~ ∆DEF, therefore,
AB/DE = BC/EF = AC/DF
AB = 8.4
DE = x
BC = 10
EF = 25
AC = 16.5
DF = 41.25
Let's find DE using AB/DE = BC/EF. Thus:
8.4/x = 10/25
Cross multiply
x*10 = 25*8.4
10x = 210
Divide both sides by 10
x = 210/10
x = 21
DE = x = 21

Answer:
(a) 260 square centimeters
Step-by-step explanation:
The figure consists of a 10 cm square and four congruent triangles with base 10 cm and height 8 cm. Using the formulas for the area of a square and a triangle, the total area is ...
area = square area + 4 × triangle area
area = s² + 4×(1/2bh) = (10 cm)²+ 2(10 cm)(8 cm) = (100 +160) cm²
area = 260 cm²

One side of a triangle is three times the shortest side.
"The third side is 7 feet more than the shortest side. The
perimeter is 62 feet. Find all three sides.
Answers
Answer:
The lengths of the sides are - 11, 18, 33
Step-by-step explanation:
Shortest side = x
Second side = 3x
Third side = 7 + x
Perimeter = sum of all three sides
62 = x + 3x + x + 7
62 = 5x + 7
55 = 5x
x = 11
Shortest side = x = 11
Second side = 3x = 33
Third side = 7 + x = 18

Answer:
According to me it should be Option B, 15.31
Hope this helps!
The expected value for the age of a randomly chosen student is,
⇒ 15.38
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that:
Total number of students,
⇒ n = 1500,
And, Age : 13, 14, 15, 16, 17, 18
Probability : 0.01, 0.25, 0.27, 0.30, 0.16, 0.01
Now,
We can Calculate the expected value as shown below,
E = 13 × 0.01 + 14 × 0.25 + 15 × 0.27 + 16 × 0.30 + 17 × 0.16 + 18 × 0.01
E = 0.13 + 3.5 + 4.05 + 4.8 + 2. 72 + 0.18
E = 15.38
Therefore, The expected value for the age of a randomly chosen student is 15.

I am thinking of a number.i add 62 to the number and divide the total by 7.the result is 4 less than the number 1 thought of.what was the number
Answers
Answer:
15
Step-by-step explanation:
let the number be n, then
[tex]\frac{n+62}{7}[/tex] = n - 4 ( multiply both sides by 7 to clear the fraction )
n + 62 = 7n - 28 ( subtract n from both sides )
62 = 6n - 28 ( add 28 to both sides )
90 = 6n ( divide both sides by 6 )
15 = n
That is the number is 15

A sailor judges the distance to a lighthouse by holding a ruler at arm's length and measuring the apparent height of the lighthouse. He knows that the lighthouse is actually 60 feet tall. If it appears to be 3 inches tall when the ruler is held 2 feet from his eye, how far away is it?
Answers
9514 1404 393
Answer:
480 ft
Step-by-step explanation:
The geometry involves two similar triangles. The ruler at arms length forms a triangle that has the opposite side 3 inches high and 24 inches (2 ft) away. That is, the distance from the eye to the ruler is 8 times the height of the ruler.
The triangle involving the lighthouse is similar. That is, the angles in it are the same, so the sides are proportional to those in the smaller (ruler) triangle. The distance to the lighthouse will be 8 times the height of the lighthouse, just as the distance to the ruler is 8 times the height of the ruler.
8 × 60 ft = 480 ft
The lighthouse is 480 feet away.
What is an equation of the line that passes through the points (8, -8) and (1, 6)?
Answers
Answer:
[tex]y=-2x+8[/tex]
Step-by-step explanation:
In slope-intercept form, the equation of a line is given by [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope of the line, [tex]b[/tex] is the y-intercept, and [tex](x,y)[/tex] represent the coordinates of any point the line passes through.
Since we're given two points the line passes through, we can find the slope of the line using the slope formula [tex]m=\frac{\Delta y}{\Delta x}[/tex]:
[tex]m=\frac{-8-6}{8-1}=\frac{-14}{7}=-2[/tex]
Now we can plug in any point the line passes through to find the y-intercept:
[tex]6=-2(1)+b,\\6=-2+b,\\b=8[/tex]
Thus, the equation of this line is equal to [tex]y=-2x+8[/tex].
