Answer:
x=26
Step-by-step explanation:
2x+3x+50=180 add like terms
5x+50=180 subtract both sides by 50
5x=130 divide both sides by 5
x=26
Answer:
x = 26
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
2x + 3x + 50 = 180
5x + 50 = 180 ( subtract 50 from both sides )
5x = 130 ( divide both sides by 5 )
x = 26

According to a recent survey, 47 percent of the people living in a certain region carry a certain genetic
trait. People from the region will be selected at random one at a time until someone is found who carries
the genetic trait. Let the random variable X represent the number of people selected to find one person
who carries the genetic trait. How many people from the region can we expect to be selected to find one
person who carries the genetic trait?

Answer:
D = 1 8.87961173
Round off to the whole number
D= 19m
Explanation of results
So to find d you will use the trigonometry formula
So you are given the
Degree which is 39°
and the hypotenuse which is 30m
Using the sin θ = Opposite Side/Hypotenuse you are going to put in the numbers where they should go in the formula so,
[tex] \sin(39) = \frac{d}{30} [/tex]
then you are going to isolate d on the right by multiplying 30 on both sides.
It will look like
30 Sin 39
So, just put this in the calculator
Kevin drove 871 miles in 13 hours. At the same rate, how many miles would he drive in 11 hours?
Answer:
737 miles
Step-by-step explanation:
So we know that he drove 871 miles in 13 hours so first you want to do 871 divided by 13 and get 67 which means he drove 67 miles in one hour. Finally you just have to multiply 67 by 11 and get 737.
Answer:
737 miles
Step-by-step explanation:
Since the distance is gonna be less it's gonna be..

Mrs. Anderson's car can go 464 miles on 16 gallons of gasoline. How many miles
can the car travel on 22 gallons of gasoline?
Answer:
638 miles
Step-by-step explanation:
Key skills needed: Proportions, Unit Rates
1) The car can go 464 miles with 16 gallons of gasoline. We need to find how many miles each gallon gasoline results in.
To find the miles per gallon, we would do 464 miles/16 gallons --> 29 mpg
This means each gallon lets the car run 29 miles.
2) To find out how many miles 22 gallons is, we then do 29 x 22, which is 638 miles.
Therefore, your answer is 638.
Hope you understood and have a nice day!!

Find the total surface area of this prism where the cross-section is an isosceles triangle
please help me
I am giving 25 points.
Answer:
620 cm²
Step-by-step explanation:
First I'll describe the net. There are 3 rectangles and 2 triangles. The triangles are identical and 2 out 3 of the rectangles are the same.
So, we know that the two similar rectangles have measurements of 13cm x 10cm. So, that's 130 cm² for one such rectangle. Add the other one and we get 260 cm².
The bottom rectangle has dimensions of 10cm x 24 cm, or 240 cm². Add that to our previous total and we'll get 500 cm².
On to the triangles. Now, we know that 1. these are isosceles triangles, and 2. they have a height of 5 cm. We can pretend to cut them in half at their highest point, which would give us 4 triangles with height 5 and length 12. Now, if you put two identical triangles together, it's a four-sided shape, and you can just multiply length by width. Let's do that.
Now we have 2 rectangles, each with width 5 and length 12. Calculate the area for each, and now we have 2 rectangles with area 60 cm². Add them together....120cm².
Add that to our previous total, and we'll get 620 cm². That should be the surface area of your prism :D

Please help me with my homework please
Solution:
1)Distance covered by cyclist=3.75 miles.
Time =0.3 hours.
Speed= Distance ÷Time
Speed =3.75÷0.3=12.5 miles per hour.
2) Speed = 12.5 miles per hour, Distance = 4.5 miles .
Time = Distance ÷Speed.
Time = 4.5÷12.5=0.36 hours.
Time taken to cover 4.5 miles is 0.36 hours.
Answer:
a) Speed of the cyclist is (2.75/0.4) = 6.875 miles per hour.
b) It will take (5.5/6.875) = 0.8 hours to travel 5.5 miles at this rate.
Remember: Speed=Distance/TimeAn art shop has 80 large boxes of markers and 34 small boxes of markers in stock. Each large box contains 48 markers and each small box contains 20 markers. Which equation could be used to find n, the total number of markers in stock?
Answer: n= 80 ×48+ 34×20
Step-by-step explanation:
Given: Number of large boxes = 80
Number of small boxes = 34
Number of markers in each large box = 48
Number of markers in each small box = 20
Total markers = (Number of large boxes)x (Number of markers in each large box) + (Number of small boxes) x (Number of markers in each small box)
Total number of markers = n (given)
Then, n= 80 ×48+ 34×20
Therefore , the equation could be used to find n, the total number of markers in stock: n= 80 ×48+ 34×20

The area of the rectangle is 64.8 square centimeters. What is the perimeter of the rectangle? One group of ten tenths and one group of eight tenths divided into six groups of three tenths. Enter your answer in the box. centimeters
Answer:
(a) [tex]Perimeter = 32.2\ cm[/tex]
(b) 100
Step-by-step explanation:
Solving (a):
Given
Shape: Rectangle
[tex]Area = 64.8[/tex]
Required
Calculate the perimeter.
Area is calculated as:
[tex]Area = L * W[/tex]
Where
[tex]L = Length[/tex] and [tex]W = Width[/tex]
Substitute 64.8 for Area
[tex]64.8 = L * W[/tex]
Make L the subject:
[tex]L = \frac{64.8}{W}[/tex]
Perimeter is calculated as:
[tex]P = 2 * (L + W)[/tex]
Substitute 64.8/W for L
[tex]P = 2 * (\frac{64.8}{W} + W)[/tex]
[tex]P = \frac{129.6}{W} + 2W[/tex]
To solve further, we take the derivative of P and set it to 0, afterwards.
[tex]dP = -\frac{129.6}{W^2} + 2[/tex]
Set to 0
[tex]0 = -\frac{129.6}{W^2} + 2[/tex]
Collect Like Terms
[tex]\frac{129.6}{W^2} = 2[/tex]
Cross Multiply:
[tex]2W^2= 129.6[/tex]
Divide through by 2
[tex]W^2 = 64.8[/tex]
Take square roots
[tex]W = \sqrt{64.8[/tex]
[tex]W = 8.05[/tex]
Recall that:
[tex]L = \frac{64.8}{W}[/tex]
So:
[tex]L= \frac{64.8}{8.05}\\[/tex]
[tex]L= 8.05[/tex]
The perimeter is:
[tex]Perimeter = 2 * (8.05 + 8.05)[/tex]
[tex]Perimeter = 2 * (16.10)[/tex]
[tex]Perimeter = 32.2\ cm[/tex]
Solving (b):
Given
((1 Group of 10 tenths) and (1 group of 8 tenths))/(6 groups of 3 tenths)
Required
Solve
[tex]Tenths = \frac{1}{10}[/tex]
So, the expression becomes:
((1 Group of [tex]10 * \frac{1}{10}[/tex]) and (1 group of [tex]8 * \frac{1}{10}[/tex]))/(6 groups of [tex]3 * \frac{1}{10}[/tex])
This gives:
((1 Group of [tex]\frac{10}{10}[/tex]) and (1 group of [tex]\frac{8}{10}[/tex]))/(6 groups of [tex]\frac{3}{10}[/tex])
Group means product, so the expression becomes:
[tex]\frac{(1 * \frac{10}{10} \ and\ 1 * \frac{8}{10})}{6 * \frac{3}{10}}[/tex]
And, as used here means addition
[tex]\frac{(1 * \frac{10}{10} + 1 * \frac{8}{10})}{6 * \frac{3}{10}}[/tex]
Simplify:
[tex]\frac{(1 * 1 + 1 * 0.80)}{6 *0.30}[/tex]
[tex]\frac{(1 + 0.80)}{1.80}[/tex]
[tex]\frac{1.80}{1.80}[/tex]
[tex]= 1.00[/tex]

Answer:
10,100,1000,-10,-100,-1000
Step-by-step explanation:
The length of a rectangle is five inches less than three times its width. If the perimeter
of the rectangle is 150 inches, find the dimensions.
L=40 in. ; W=35 in.
L=60 in. ; W=45 in.
L=50 in. ; W=25 in.
L=55 in. ; W=20 in.
Answer:
L = 55 in, W = 20 in
Step-by-step explanation:
Hi there!
First we have to set up an equation for the length, which can be written as 3x - 5.
The formula for perimeter of a rectangle is 2l + 2w = p, so we can plug in some values here.
l = 3x - 5
w = x
[tex]2(3x-5) + 2(x) = 150[/tex]
Now we just have to solve!
[tex]6x - 10 + 2x = 150[/tex]
When we combine like terms and add ten to both sides, we are left with
[tex]8x = 160[/tex], which means x = 20
Using this, that means the width is 20
We can find the perimeter by plugging 20 in for x. [tex]l = 3(20) -5[/tex]
This means the length is 55.
