Answer:
1/3
Step-by-step explanation:
I have a certain way of doing this, I will start from the Y-intercept, let's say its (0, 2), then, if the next point is (3, 4) i will count up 1, to get to point 3 on the graph, then count left/right to point 4. Thus making my slope 1/2.
Hope that made sense!

The distribution of height of adult american women is approximately normal with a mean of 65.5 inches and a standard deviation of 2.5 inches what percentage of women are taller than 70.5 inches?
Answer:
2.275%
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x-mean)SD
here, x = 70.5
mean = 65.5
SD = 2.5
Substituting these values;
z = (70.5-65.5)/2.5
= 5/2.5 = 2
So we want to calculate the probability that;
P( z> 2)
We check the standard normal distribution table for this
That will be
0.02275
In percentage, this is 2.275 %

At a sale, coats were sold for $76 each. If the coats originally cost $80 each, what percentage of its original price was a coat sold for?
the difference of two numbers is 72 and their quotient is 10 plz help
Answer:
The numbers would be 80 and 8
Step-by-step explanation:
Hope this helps
Answer:
We have, x - y = 72
and, x = 10y
so, 10y - y = 72
y = 8
so, x= 80

Answer/Step-by-step explanation:
✔️Using trigonometric ratio, find width of the rectangle, BD:
Thus:
[tex] tan(\theta) = \frac{opposite}{adjacent} [/tex]
Where,
[tex] tan(\theta) = tan(60) = \sqrt{3} [/tex]
Opposite = BD
Adjacent = 7 cm
Plug in the values
[tex] \sqrt{3} = \frac{BD}{7} [/tex]
Multiply both sides by 7
[tex] 7\sqrt{3} = BD [/tex]
[tex] BD = 7\sqrt{3} [/tex]
✔️Using trigonometric ratio, find height of the rectangle, BF:
Thus:
[tex] tan(\theta) = \frac{opposite}{adjacent} [/tex]
Where,
[tex] tan(\theta) = tan(60) = \sqrt{3} [/tex]
Opposite = 6 cm
Adjacent = BF
Plug in the values
[tex] \sqrt{3} = \frac{6}{BF} [/tex]
[tex] BF = \frac{6}{\sqrt{3}} [/tex]
Rationalize
[tex] BF = \frac{6 \times \sqrt{3}}{\sqrt{3} \times \sqrt{3}} [/tex]
[tex] BF = \frac{6\sqrt{3}}{3} [/tex]
[tex] BF = 2\sqrt{3} [/tex]
✔️Perimeter of rectangle BDEF:
Perimeter = 2(BD + BF)
Plug in the values
[tex] Perimeter = 2(7\sqrt{3} + 2\sqrt{3}) [/tex]
[tex] Perimeter = 2(9\sqrt{3}) [/tex]
[tex] Perimeter = 18\sqrt{3} [/tex]
✔️Area of the rectangle BDEF:
Area = BD × BF
Plug in the values
[tex] Area = 7\sqrt{3} \times 2\sqrt{3} [/tex]
[tex] Area = 7 \times 2\sqrt{3 \times 3} [/tex]
[tex] Area = 14 \times 3 [/tex]
[tex] Area = 42 [/tex]
6. A rental car agency charges $240 per week plus $0.25 per mile to rent
a car. The charge for a minivan is $180 per week plus $0.40 per mile.
After how many miles is the total charge for each vehicle the same?
Answer:
400 Miles
Step-by-step explanation:
Set up the equations and make them equal to each other and then solve.
240+0.25m=180+0.40m
Answer
400 miles
Step-by-step explanation:
After 400 miles, both will be costing the same, you first create an equation with the values you have, for example, 240 + .25x and you either graph them and find the intersection or guess and check.

You have at most 8 hours to spend at a beach and at a planetarium. You want to spend more than 2 hours at the beach and at least 2 hours at the planetarium. Let x be the number of hours at the beach and let y be the number of hours at the planetarium. Which system represents the situation
Answer:
x > 2
y ≥ 2
x + y ≤ 8
Step-by-step explanation:
Here, we want to write a system of equations according to the given variables
More than means, greater than
since x is the variable we want to use;
x > 2
At least 2 hours means greater than or equal to 2
That is mathematically represented as;
y ≥ 2
At most means less than or equal to
So;
x + y ≤ 8

Answer:
the last one [d)]
Step-by-step explanation:
First, we need to use the triangle inequality theorem. The sum of the lengths of the two sides must be greater than the third side.
a) 7+14=21=21 (this cannot represent a triangle)
b) 13+23=36<37 (this cannot represent a triangle)
c) 7+18=25=25 (this cannot represent a triangle)
d) 11+24=35>32 (this can represent a triangle)
d) is the answer

Answer:
498
Step-by-step explanation:
So,if mike stacked 249 legos and thomas did twice as much that means x2 so if you do 249 x2 you get 498.

Answer:
b (5x+4y=32) is the correct answer
Step-by-step explanation:
if it is parallel then the slop has to be the same which means you can eliminate choices a and c. then, you can plug in the points they give you to see if the statement holds true.
5x+4x
5(12)+4(-7)
60-28
32
therefore, option b is correct
Arc math problem
Thanks
Answer:
Option D
Step-by-step explanation:
17). Area of a sector of a circle = [tex]\frac{\theta}{360}(\text{Area of the circle})[/tex]
= [tex]\frac{\theta}{360}(\pi r^{2} )[/tex]
Here 'r' = radius of the circle
From the picture attached,
r = 10 ft
θ = 300°
Area of the sector = [tex]\frac{300}{360}[\pi (10)^{2}][/tex]
= [tex]\frac{5}{6}(100\pi )[/tex]
= [tex]\frac{250\pi}{3}[/tex]
Area of the sector = [tex]\frac{250\pi}{3}[/tex] ft²
Therefore, Option (D) will be the correct option.
Answer:
area of greater arc/sector=300/360 ×πr²=5/6 ×π10²=250π/3 ft²

3x + 5 = 2x + 7 What should you do first to isolate the variable?
Answer:
you can subtract 2x from both sides
Then subtract 5 from both sides.
x = 2 is what the equation gives you
Step-by-step explanation:
You can do one of two things.
1. You can subtract 2x from both sides of the equation
or
2. You can subtract 5 from both sides of the equation.
Either one will give you the correct answer.
3x - 2x + 5 = 2x - 2x + 7 Combine the xs
1x + 5 = 7 Subtract 5 from both sides.
x + 5-5 = 7-5
x = 2
Answer:
subtract the lowest variable from the highest variable.
Step-by-step explanation:
3x+5=2x+7
1x+5=7
add the 5 to the 7
12
divide 12 and the 3x
