Answer:
Answer is 3.2
Step-by-step explanation: you can take any percent and divide it by 100. So in this example you would divide 320/100 and it will give you 3.2
Suppose you add two linear equations that form a system, and you get the result y = −2. How many solutions does the system have?
Answer:
This system will have 1 solution
Step-by-step explanation:
A linear system that has exactly one solution is called a consistent independent system. Consistent means that the lines intersect and independent means that the lines are distinct. Linear systems composed of lines that have the same slope and the y-intercept are said to be consistent dependent systems.

Answer:
m<2 = 70degrees
m<3 = 70degrees
m<4 = 110degrees
m<5 = 110degrees
m<6 = 70degrees
m<7 = 70degrees
m<8 = 110degrees
Step-by-step explanation:
A line has the angles of 180 degrees so if m<1 is 110 then m<2 must be 70degrees. Then m<4 is opposite side of m<1 so it has to be the same number of degrees and the same for m<3 is the opposite side of m<2.
You repeat the process with 5678

grocery store workers restock cans of soup and bags of rice at constant rates. which item was restocked at a faster rate and what is the rate? let x represent the number of minutes and y represent the total number of bags or cans
Answer:
Cans of soup are restocked at a faster rate
Step-by-step explanation:
With an equation y=mx+b, m = slope
m of rice = 12
The slope of the graph for the cans of soup is 30/2 = 15
m of soup = 15
15 is greater than 12

The sum of two numbers is 200 and the two numbers in a ratio of 2.3. What is the larger number
Answer:
the larger number is 120
Step-by-step explanation:
sum of number = 200
total ratio = 2 + 3 = 5
ratio 1 = 200 ÷ 5 = 40
ratio 2 = 40 × 2 = 80
ratio 3 = 40 × 3 = 120
The tortoise versus the hare: The speed of the hare is given by the sinusoidal function H(t) = sin(t) and the speed of the tortoise is T(t) = cos(t), where t is time measured in hours and the speed is measured in miles per hour. Find the area between the curves from time t = 0 to the first time after one hour when the tortoise and hare are traveling at the same speed. What does this area represent?
a. The total distance traveled by both the hare and tortoise during that time.
b. The difference in the distance traveled by the tortoise and hare during that time.
c. The average difference in velocity between the tortoise and hare during that time.
d. The difference in velocity between the tortoise and hare during that time.
Answer:
b. The difference in the distance traveled by the tortoise and hare during that time.
Step-by-step explanation:
First the intersection points are found out on the graph. Then the area between the curves is found out.
Putting the values
H(t) = sin(t)
H(t) = sin(1) = 0.01745
T(t) = cos(t),
T(t) = cos(1)= 0.9998
As T(t) ≥ H(t)
Area is found out by taking the integral of it.
Area = Integral ( limit 0 to 0.998) T(t)-H(t) dt
The difference represents how far the turtle is from the hare.
So it represents the difference in the distance traveled by the tortoise and hare during that time.

Compare the dimensions of the prisms. How many times greater is the surface area of the green prism than the surface area of the blue prism?
I will ONLY give a brainliest to whoever answers the questions CORRECTLY!
Answer:
The surface area of the green prism is 6.25 times greater than the surface area of the blue prism.
Step-by-step explanation:
The surface area of both prisms consists of six rectangles: top, base, front, back, left side and right side. In terms of surface area, top=base, front=back and left side=right side, so the total surface area for each prism is:
2(base area)+2(back area)+2(side area)
=2((base area)+(back area)+(side area))
Area of blue prism = 2((base area)+(back area)+(side area))
=2((4*2)+(4*10)+(2*10))
=2(8+40+20)
=2(68)
=136 cm²
Area of green prism = 2((base area)+(back area)+(side area))
=2((10*5)+(25*10)+(25*5))
=2(50+250+125)
=2(425)
=850 cm²
850cm² is 6.25 times greater than 136cm² (850/136=6.25), so therefore, the surface area of the green prism is 6.25 times greater than the surface area of the blue prism.

Find the volume of the pyramid.
I will ONLY give you a brainliest if your answer is CORRECT!
Answer:
72 cm³
Step-by-step explanation:
Volume of a triangular pyramid = a*(h/3), where a is the area of the base triangle and h is the height from the base to the highest point.
We need to first find a, the area of the bas triangle:
Area of triangle = (1/2)bh, where b is the length of the base and h is the perpendicular height.
a = (1/2)12*4
a = 6*4
a = 24 cm²
Knowing a, we can know find the volume:
Volume = a*(h/3)
= 24*(9/3)
= 24*3
= 72 cm³

Create an algebraic expression to solve the following problems.
a) Jeff’s cell phone plan charges him $10 per GB with no extra fees. How much will his bill be for 6 GB?
b) Marks cell phone charges him $8 per GB and a monthly fee of $15 how much will his bill be for 10 GB
c) Ricks cell phone plan charges him $5 per GB and a monthly for of $30. How much will his bill be for 2 GB?
PLEASE ANSWER PLEASE
Answer:
Step-by-step explanation:
x is the number of GB
f(x) is the cost in dollars
f(x) = 10x
Bill for 6 GB = f(6) = 60
:::::
f(x) = 8x+15
Bill for 8 GB = f(10) = 95
:::::
f(x) = 5x+30
Bill for 2 GB = f(2) = 40
Marina is drawing a plan for a new garden. The rectangle plotted in the coordinate plane represents the garden, measured in feet. How much soil will she need to cover the garden? 10 ft2 12 ft2 20 ft2 24 ft2
Answer:
Step-by-step explanation:
You need to upload a picture and i can answer underneath.
Usually if measured in feet then we have a scale = 1cm -1ft maybe.
so if you measure 3cm x 4cm then we have 12cm area = 12ft area if. Or if you have 2cm x 5cm = 10cm area = 10ft area if you have 4cm x 5cm = 20cm = 20ft area
etc. etc. Just make sure you say cm then ft in scale conversion.

Answer:
a=8 b=3/2
Step-by-step explanation:
so here a is the initial value which 8
then we can plug in 2 for x and 18 for f(x) to find b
f(x)=8*b^x
18=8*b^2
18/8=b^2
9/4=b^2
b^2=(3/2)^2
b=3/2

please answer ASAP.
a) y=-3/2x+5
b) y=-2/3x+5
c) y=-3/2x+3 1/2
d) y=-2/3x+3 1/2
Answer:
d) y= -2/3x+3 1/2
Step-by-step explanation:
Points on the graph: ( -4, 6) and ( -7, 8)
Slope:
m=(y2-y1)/(x2-x1)
m=(8-6)/(-7+4)
m= 2/(-3)
m= -2/3
Slope-intercept:
y - y1 = m(x - x1)
y - 6 = -2/3(x + 4)
y - 6 = -2/3x - 8/3
y = -2/3x + 3 1/2
