Step-by-step explanation:
2500 divided by 52 (number of weeks in a year)=
625 divided by 13= 48.076923
about 48 miles
Answer:
The answer is is 48.1 miles Every week
Step-by-step explanation:
We know that there are 52 weeks in the year and beyond 2500 mpt now we can calculate the number of miles that are conducted every week through

Find the area of the figure
Answer:
Step-by-step explanation:
i cant give you an exact answer but look up the formula for trapezoid and look up the formula for triangle and you will get your answer.
Answer: Area 89m^2
Step-by-step explanation:
To find the area of the rectangle we multiply
Base * Height = Area
8 * 13 = 104
Now we find the area that isn't shaded
I inference that the base of the triangle is 5m
5 * 6 = 30
Now divide that by 2
30/2 = 15
Subtract 15 from 104
104 - 15 = 89m^2

Answer:
The ordered pair (15, 12) means that 15 pounds of beans cost $12.
Step-by-step explanation:
(20, 16)
(x, y)
x is along the x-axis and y is along the y-axis.
x = 20 = 20 pounds of beans
y = 16 = 16 is the cost of the beans
(15, 12)
x = 15 is 15 pounds of beans
y = 12 is 12 for the cost of the beans
Answer: 15 pounds of beans costs 12 dollars
Step-by-step explanation:
if the x-axis represents the pounds of beans, then any x-coordinate will be beans.
Which of the following numbers are less than -0.625
A) -8/5
B) -5/8
C)-0.5
*Choose all that apply*
Answer:
A) -8/5
Step-by-step explanation:
First, convert -8/5 and -5/8 to decimals
-8/5 = -1.6
-5/8 = -0.625
-0.5 is greater than -0.625 because it is closer to 0.
So, the only number less than -0.625 is -8/5, which is equivalent to -1.6
So, the correct answer is A) -8/5

7400 times 7.5/100
=74 times 7.5
=$555.00
7400-555=$6845.00
Given that triangle LMN is
similar to triangle GJH, what is
the value of x?
Answer:
x = 53
Step-by-step explanation:
Similar means that the corresponding angles are congruent (the same) - basically what this means is that ∠L ≅ ∠G, ∠M ≅ ∠J, and ∠N ≅ ∠H.
Since we know that the angle measures in a triangle should add up to 180 and we know the measures of ∠L and ∠M already, we can do
180 = 67 + 60 + N
So, N = 180 - (67 + 60) = 180 - 127 = 53.
Since ∠N ≅ ∠H, ∠H = 53.

PLEASE HELP ITS DUE SOIN AND I DONT KNOW HOW TO ANSWER
Answer:
y = - 3
Step-by-step explanation:
Given the 2 equations
6x + 11y = - 3 → (1)
4x + y = = 17 → (2)
Multiplying (1) by 4 and (2) by - 6, then adding will eliminate the term in x
24x + 44y = - 12 → (3)
- 24x - 6y = - 102 → (4)
add (3) and (4) term by term to eliminate x
0 + 38y = - 114
38y = - 114 ( divide both sides by 38 )
y = - 3
Please help!!!! The roots of x^2-2x-2=0 are A.1+square root of 3 B.1+square root of 12 or C.No real roots
Answer:
A
Step-by-step explanation:
We have the equation:
[tex]x^2-2x-2=0[/tex]
We can use the quadratic formula. In this case, a = 1, b = -2, and c = -2. Hence:
[tex]\displaystyle x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-2)}}{2(1)}[/tex]
Evaluate:
[tex]\displaystyle x=\frac{2\pm\sqrt{12}}{2}[/tex]
Simplify:
[tex]\sqrt{12}=\sqrt{4}\cdot\sqrt{3}=2\sqrt{3}[/tex]
Hence:
[tex]\displaystyle x=\frac{2\pm2\sqrt{3}}{2}[/tex]
Divide:
[tex]x=1\pm\sqrt3[/tex]
The correct answer is A.

If a chord of a circle is 6 and is twice as far from the center chord of length 12, how long is the radius of the circle?
Answer and explanation:
A center chord in a circle is the diameter of that circle. Therefore a center chord of a circle is different from other chords that touch two points on the circle but not in the center of the circle. A diameter of a circle is the chord that runs the length of the center of the circle touching two points at the edge of the circle. A diameter is twice the radius of the circle. So if the diameter of the circle is 12cm then the radius of the circle is 6cm

A movie theater sells out 7 times per month. Chloe counted 168 sellouts at the theater. How long was Chloe recording sales?
A. 7 years
B. 2 years
C. 1 year
D. 24 years
More questions will be asked in the comments
Answer:
B. 2 years
Step-by-step explanation:
use y = mx + b
y = total number of sell outs = 168
m = sell outs per month = 7
x = months
b is not needed for this
168 = 7x
divide both sides by 7
x = 24
divide 24 by 12 to get the number of years
years = 2
Answer:
the answer to this question is B. 2 years

[tex]10\sqrt{12x^{3} } . 2\sqrt{6x^{5} }[/tex]
full calculations please!!
Answer:
[tex]120x^4\sqrt{2}[/tex]
Step-by-step explanation:
First we need to break down the numbers in the radicals into its factors
so
12= 3*2*2
x³=x*x*x
Which means we have
[tex]10\sqrt{3*2*2*x*x*x}=20x\sqrt{3x}[/tex]
and
[tex]2\sqrt{2*3*x*x*x*x*x} =2x^{2} \sqrt{6x}[/tex]
Because the radicand (the small number that goes up top) are the same we can just mulitply the two from here
which means we have
[tex](20x*2x^2)\sqrt{3x*6x}=40x^3\sqrt{18x^2} \\\sqrt{18x^2}=\sqrt{2*3*3*x*x} =3x\sqrt{2} \\=120x^4\sqrt{2}[/tex]
