3) What is 2/15 + 3/10 ? (hint: find the LCD first)
Answer:
13/30
Step-by-step explanation:
2/15 x 2 = 4/30
3/10 x 3 = 9/30
4/30 + 9/30 = 13/30
Answer:
13/30
Step-by-step explanation:
2/15 = 2/15 × 2/2 = 4/30
3/10 = 3/10 × 3/3 = 9/30
4/30+9/30=13/30
A farmer Harvester 21 1/4 so if you were a bushel of sweet corn this year than previous year it's a farmer sweet corn crops planted across 3 acres was the average loss Per acre
Answer:
7 1/12 bushels of sweet corn per acre of land
Step-by-step explanation:
Total bushels of sweet corn harvested this year fewer than the previous year = 21 1/4
Total acres of land used to plant = 3 acres
what is the average loss per acre?
Average loss = Total bushels of sweet corn harvested for the year / 3 acres
= 21 1/4 ÷ 3
= 85/4 ÷ 3
= 85/4 × 1/3
= 85 / 12
= 7 1/12
Average loss = 7 1/2 bushels of sweet corn per acre of land

Answer:
165
Step-by-step explanation:
We solve the first 5
1*(10-1)=9
2*(10-2)=16
3*(10-3)=21
4*(10-4)=24
5*(10-5)= 25
and notice
when you go from 6 on its getting the same number because say 3*(10-3) = 3*7 and 7*(10-7) = 7*3 and 7*3 = 3*7 so
You add the first 5 integer you solved up
9 16 21 24 25 = 95
and then you double it no extra 25
and then you get 165 = answer

The toll on a highway is based on the number of miles driven. If the toll on a 15-mile stretch of highway is $0.60, find the cost to drive a 80-mile stretch.
Answer:
$3.20
Step-by-step explanation:
We have
15-mile stretch = $0.60
80-mile stretch = x
Cross Multiply
15 × x = 80 × $0.60
x = 80 × $0.60/15
x = $3.20
Hence, the cost to drive a 80-mile stretch is $3.20

If an exterior Angele of a regular polygon is an integer, what are the possible values of the angle?
Answer:
Please read the explanied answer below.
Step-by-step explanation:
As we know that polygon is a shape that consists of at least three sides.The sum of exterior angles of any polygon = [tex]360^{\circ }[/tex]We also know that a regular polygon has all the angles equal and all sides have the same length.
As we know:
Exterior angle = 360° ÷ No. of sidesWhen the number of sides changes, the angle also changes. Therefore, we would get different integers as answer.
For example:
In terms of a triangle:
Exterior angle = 360° ÷ No. of sides
= 360° ÷ 3 = 120°
In terms of a rectangle:
Exterior angle = 360° ÷ No. of sides
= 360° ÷ 4 = 90°
and in the same way
360° ÷ 5 = 72 °
360° ÷ 6 = 60 °
360° ÷ 8 = 45 °
360° ÷ 9 = 40°
and so on.

What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Teacher Malone is reviewing papers in the educators' parlor. She has previously gotten done with reviewing 20 tasks and is evaluating 5 additional tasks each hour. Her showing colleague just came in to help her. He can grade at a pace of 7 tasks consistently.
Let 'x' be the number of hours and 'y' be the number of assignments. Then the equations are given as,
y = 5x + 20 ...1
y = 7x ...2
At some point, they will be finished and will have graded the same number of papers. Then from equations 1 and 2, we have
7x = 5x + 20
7x - 5x = 20
2x = 20
x = 20 / 2
x = 10
The number of papers checked by both becomes equal in 10 hours.

Percy planted 4 tomato plants the first week of spring. He planted 11 tomato plants the second week of spring. What is the percent increase in the number of plants Percy planted? Round your answer to the nearest whole percent.
Answer:
175%
Step-by-step explanation:
The formula for Percent increase =
Final value - Initial value/Initial value × 100
Final value = 11 tomato plant
Initial value = 4 tomato plant
Percent Increase = 11 - 4/4 = 100
= 7/4 × 100
= 175%

If the Jackson family drive 135 miles on 6 gallons of gas, how many miles can they can they drive on 9 gallons?
Answer:
202.5 miles
Step-by-step explanation:
We find the unit rate of the mile per gallon
135/6
= 22.5
We multiply 22.5 by 9 to get the miles they can drive on 9 gallons
22.5 * 9
= 202.5
Answer:
202.5 miles
Step-by-step explanation:
135 miles divided by 6 = 22.5 x 9 = 202.5 miles
6 gallons divided by 6 = 1 gallon x 9 = 9 gallons

A room has an area of 432 ft2. One dimension is 6 ft more than the other. Find the dimensions of the room.
Answer:
W=18ft
L=24ft
Step-by-step explanation:
Step one:
given data
area= 425ft^2
let the width W be =x
and the length L be =x+6
Required
Length and width
solution
Area= lenth*width
432=x*(x+6)
432=x^2+6x
x^2+6x-432=0
The roots of the quadratic equation is
x=-24-----can not be negative
x=18----correct
The dimension is
the width W =x=18ft
The length= x+6=18+6=24ft
check area= 18*24=432ft^2

A person and a building cast a shadow at the same time of day. The person is 5.8 feet tall and cast a shadow of 3.2 feet.
The building casts a shadow of 28 feet.
Answer: The height of the building is 50.75 feet.
Step-by-step explanation:
The ratio between the height of the object and the casted shadow must be equal for all the objects, as the angle at which the source if light impacts them is the same.
For the person, we know that it is 5.8ft tall, and the shadow is 3.2ft long.
The ratio will be: 5.8ft/3.2ft = 1.8125
Now, if H is the height of the building, and the shadow that the building casts is 28ft, we must have:
H/28ft = 1.8125
Now we can solve this for H.
H = 1.8125*28ft = 50.75 ft
Then the height of the building is 50.75 feet.

How do I solve this using the quadratic formula? −6x^2−2−3x=−8
Could you also show your work?
Thanks
Answer:
[tex]x=\frac{-1}{4} +/-\frac{1}{4}\sqrt{17}[/tex]
Step-by-step explanation:
First, we need to get the equation into the polynomial form. Add 8 to both sides:
[tex]-6x^{2} -2-3x=-8[/tex]
[tex]-6x^{2} +6-3x=0[/tex]
Rearrange the equation so that it is in standard form:
[tex]-6x^{2} -3x+6=0[/tex]
Remember the quadratic formula:
[tex]\frac{-b+/-\sqrt{b^{2}-4ac} }{2a}[/tex]
[tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] are the coefficients of the problem when it is in standard form. In this case, [tex]a=-6[/tex], [tex]b=-3[/tex], and [tex]c=6[/tex]. Now, all we need to do is plug those into the quadratic formula.
[tex]\frac{-(-3)+/-\sqrt{(-3)^{2}-4(-6)(6)} }{2(-6)}[/tex]
Simplify:
[tex]\frac{3+/-\sqrt{153}}{-12}[/tex]
[tex]x=\frac{-1}{4} +/-\frac{1}{4}\sqrt{17}[/tex]
Hope this helps!
Which graph shows a polynomial function with an even degree?
Answer:
c
Step-by-step explanation:
im smart
The graph that shows a polynomial function with an even degree is option D.
What is a Function?A function is a law that relates two variables, a dependent and an independent variable with each other.
The domain and range of a function is always defined, the domain is all the values that can be an input to the function and the range is all the valuess that a function can have.
A function that involves positive integer powers as exponents of a variable in an equation is called a polynomial function, like the quadratic equation,
An even degree polynomial function, represented by y = x², have graphs that either open upwards or downwards.
A function is even if, for each x in the domain of f, f (- x) = f (x).
In an even function, the graph is symetrically along y axis.
The only graph that is symmetrical along the y axis is graph D.

The school band is selling sweatshirts and baseball caps to raise $9000 to attend a band competition Sweatshirts cost $25 each and baseball caps cost $10 each. The equation 25x + 10y = 9000 models this situation, where x is the number of sweatshirts sold and y is the number of baseball caps sold. The number of shirts sold is 258 X - intercept = y - intercept = How many caps were sold?
x int:
y int:
how many caps were sold? :
Answer:
255 caps were sold
Step-by-step explanation:
25x+10y = 9000
25(258) + 10y = 9000
6450 + 10y = 9000
-6450 + 10y = -6450
10y = 2550
2550/10y
y = 255
