write 7.75 x 10^-3 in standard notation
Answer:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
7.75 × 10^−3
7.75 x 10^-3 in standard notation is 0.775

PLEASE HELP!!!!! "A country's population in 1991 was 70 million. In 1998 it was 74 million. Estimate the population in 2010 using the exponential growth formula. Round your answer to the nearest million."
Answer:
81 million
Step-by-step explanation:
A = Pe^rt
Let's break this equation down.
A is the total you will have.
P is the starting value.
R is the rate
T is the time.
Let's find the rate first.
74000000 = 70000000e^7r
Divide each side by 70mil
74000000/70000000 = e^7r
Then take the ln() of each side.
ln(74000000/70000000) = 7r
0.0556 = 7r
r = 0.0079
Now we can find how many people will be there in 2010.
A = 70,000,000e^(19 * 0.0079)
A = 81336530.2373
Now we round to the nearest million, leaving us with 81 million.

Greta’s family drinks 3 1/4 quarts of milk and 1 5/6 quarts of juice in one week. About how much more does Greta’s family drink in one week
To find out how much liquid Greta's family consumes weekly, we sum up 3 1/4 quarts of milk and 1 5/6 quarts of juice. After converting them to have a common denominator and adding, we determine the total consumption is about 5 1/12 quarts per week.
Explanation:The question: How much more does Greta's family drink in one week, if they consume 3 1/4 quarts of milk and 1 5/6 quarts of juice? To find the total amount of liquid Greta's family drinks in a week, we need to add the quarts of milk to the quarts of juice. Since these are fractional amounts, let's start by finding a common denominator. For fractions with denominators 4 and 6, the common denominator would be 12. Convert 3 1/4 quarts of milk to 13/4, which is equivalent to 39/12 quarts. Convert 1 5/6 quarts of juice to 11/6, which is equivalent to 22/12 quarts. Now that we have a common denominator, we can add these two amounts together.
Addition of fractions with common denominators:
Quarts of milk: 39/12 quartsQuarts of juice: 22/12 quartsAdding these we get 39/12 quarts + 22/12 quarts = 61/12 quarts. To convert this into a mixed number, we divide 61 by 12, which gives us 5 with a remainder of 1, so we have 5 1/12 quarts. Therefore, Greta's family drinks a total of about 5 1/12 quarts of milk and juice in a week.

What is the area of this irregular shape
➷ Find the area of the rectangle first:
Area of rectangle = length x width
Substitute the values in:
Area = 8 x 16
Area = 128
Now find the area of the triangle:
Area = (b x h)/2
Area = (1.5 x 6) / 2
Area = 4.5
As there are two right triangles, multiply this value by 2
4.5 x 2 = 9
Add this value to the area of the rectangle:
128 + 9 = 137
The area is 137 square feet.

1. Find the shaded area of each figure, round your answer to one decimal place if necessary.
Answer:
Part a) [tex]114.3\ yd^{2}[/tex]
Part b) [tex]49.5\ yd^{2}[/tex]
Step-by-step explanation:
Part a) we know that
The area of the shaded figure is equal to the area of semicircle plus the area of a triangle
Find the area of semicircle
The area of a semicircle is equal to
[tex]A=\frac{1}{2}\pi r^{2}[/tex]
we have
[tex]r=5\ yd[/tex]
substitute
[tex]A=\frac{1}{2}\pi (5)^{2}=12.5 \pi\ yd^{2}[/tex]
Find the area of triangle
The area of the triangle is equal to
[tex]A=\frac{1}{2}(b)(h)[/tex]
we have
[tex]b=15\ yd[/tex]
[tex]h=5(2)=10\ yd[/tex] -----> the height of triangle is equal to the diameter of semicircle
substitute
[tex]A=\frac{1}{2}(15)(10)=75\ yd^{2}[/tex]
Find the area of the shaded figure
[tex]12.5 \pi\ yd^{2}+75\ yd^{2}=(12.5 \pi+75)\ yd^{2}[/tex]
assume
[tex]\pi=3.14[/tex]
[tex](12.5(3.14)+75)=114.3\ yd^{2}[/tex]
Part b) we know that
The area of the shaded figure is equal to the area of the triangle minus the area of the circle
Find the area of the circle
The area of the circle is equal to
[tex]A=\pi r^{2}[/tex]
we have
[tex]r=5\ yd[/tex]
substitute
[tex]A=\pi (5)^{2}=25 \pi\ yd^{2}[/tex]
Find the area of triangle
The area of the triangle is equal to
[tex]A=\frac{1}{2}(b)(h)[/tex]
we have
[tex]b=16\ yd[/tex]
[tex]h=16\ yd[/tex]
substitute
[tex]A=\frac{1}{2}(16)(16)=128\ yd^{2}[/tex]
Find the area of the shaded figure
[tex]128\ yd^{2}-25 \pi\ yd^{2}=(128-25 \pi)\ yd^{2}[/tex]
assume
[tex]\pi=3.14[/tex]
[tex](128-25(3.14))=49.5\ yd^{2}[/tex]
a) The area of the shaded figure [tex]114.3yd^{2}[/tex]
b) The area of the shaded figure=[tex]49.5yd^{2}[/tex]
How can the shaded area be calculated?Part a) The area of the shaded figure= (the area of semicircle)+ (the area of a triangle)
Area of semicircle= [tex]A=\frac{\pi r^{2} }{2}[/tex] where r = radius = 5
[tex]A=\frac{\pi 5^{2} }{2} =39.3 yd^{2}[/tex]
The area of the triangle= [tex]\frac{1}{2} base *height[/tex]
base = 15
height=10
The area of the triangle= [tex]\frac{1}{2}*15 *10 =75 yd^{2}[/tex]
The area of the shaded figure=39.3+75= [tex]114.3yd^{2}[/tex]
Part b) The area of the shaded figure =( the area of the triangle) -(area of the circle)
The area of the triangle=[tex]\frac{1}{2} base *height[/tex]
base and height = 16
Area=[tex]\frac{1}{2} *16*16=128yd^{2}[/tex]
The area of the circle=[tex]\pi r^{2} =3.142*5^{2} = 78.55 yd^{2}[/tex]
[tex]128 yd^{2} -78.55 yd^{2} =49.5yd^{2}[/tex]

Step-by-step explanation:
A rental car agency charges $ 220.00 per week plus $ 0.25 per mile to rent a car. How many miles can you travel in one week for $ 457.50 question mark
The correct answer is 950 miles because $457.50 - $220.00 = $237.50 and $237.50 divided by $0.25 = 950
Hope this helps.
If a car rental agency charges $220.00 per week and an additional $0.25 per mile, you could travel up to 950 miles in one week for a total cost of $457.50. The calculation was done by subtracting the base fee from the total budget and then dividing it by the cost per mile.
Explanation:The subject here is how to solve an algebraic problem involving the cost of car rental and the distance traveled. In this situation, the rental car agency charges a weekly rental fee of $220.00 and an additional $0.25 cost per mile driven. So to find out how many miles can be driven in a week for a total cost of $457.50, we'll need to perform a two-step calculation.
First, subtract the base fee from the total amount: $457.50 - $220.00 = $237.50. This is the total amount you have left for the mileage cost.
Second, divide this amount by the cost per mile. So, $237.50 / $0.25 = 950 miles. Therefore, for a total cost of $457.50, you could travel up to 950 miles in one week.

a fencing company charges $22 per foot to install a wood fence how much will it cost to install a wood fence around a rectangular pool area that is 20 feet wide and 38 feet long
We need to first find the perimeter, so 2(20+38) = 116 feet
Next we multiply 116 by 22 to get $2552
Answer:
Cost to fence the rectangular pool = $2552
Step-by-step explanation:
To find the cost to fence the rectangular pool, we need to find the perimeter of the rectangular pool.
Given: length = 38 feet and wide = 20 feet
Perimeter of a rectangle = 2(length + width)
Now plug in the given values in the above formula, we get
Perimeter of the rectangle pool = 2 (38 + 20)
= 2(58)
= 116 feet
A fencing company charges $22 per foot to install a wood fence.
To fence 116 feet, we need to multiply $22 and 116.
Cost to fence the rectangular pool = $22*116 = $2552.

34z = 36z - 7
MO = 119
Step-by-step explanation:
A line segment with a midpoint means the segment has been divided into two equal segments. This means each segment is equal to the other OM = OP.
You can solve for z by setting them equal to each other.
34z = 36z - 7
-2z = -7
z = 7/2
To find MO, substitute z = 7/2 into the equation OM = 34z.
