The area for the circle below is
in.2.
Use 3.14 for π and type your answer to the nearest tenth.
D = 5in
I NEED HELP OR I WILL FAIL
Answers
Answer:
19.63 inches
Step-by-step explanation:
The area of a circle is found by using the formula
A = πr²
r is the radius of the circle, which is the diameter divided by two.
D = 5 in so r = D ÷2
5 ÷ 2 = 2.5 inches for the radius.
A = π (2.5)²
A = π (6.25)
A = (3.14)(6.25)
A = 19.625 inches
Circle A has a radius of 4 centimeters.

What is the LCM of 5xy and 10y² ?
Answers
Answer: 10xy²
We can type 10xy^2 to mean the same thing.
==========================================
Explanation:
The LCM of the coefficients 5 and 10 is 10. Note how 5 is a factor of 10.
For the variable portions, you select the terms that are unique and have the highest exponent. We have an x term with exponent 1 and y term with exponent as high as 2. So that's why we go with xy² as the variable portion.
Overall, we end up with an LCM of 10xy²

A diver was at 58m below sea level.The diver swam up 4m every 12 seconds. Where is the location of the diver after 2 minutes?
Answers
Answer:
18 metres below sea level.
Step-by-step explanation:
Since the diver swims up 4 metres every 12 seconds, that means the diver swims up 4 * (60/12) metres = 20 metres every minute. Therefore, he will have swum up 20 * 2 = 40 metres after 2 minutes. Factoring in the diver's original position, -58m, we can calculate his position to be -58 + 40 metres = -18 metres, meaning 18 metres below sea level.

Answers
Answer:
8 and 9
Step-by-step explanation:
let 'n' = smaller positive integer
let 'n+1' = larger
n² = 5(n+1)+19
n² = 5n + 5 + 19
n² = 5n + 24
n² - 5n - 24 = 0
(n-8)(n+3) = 0
n = 8 [this is the smaller positive integer]
n+1 = 9 [this is the larger positive integer]
n = -3 [this value can be discounted because it is not positive]

Which sequence is generated by the function f(n + 1) = f(n) – 2 for f(1) = 10?
Answers
Answer: The sequence generated is 10, 8, 6, 4, 2, ...
This sequence is arithmetic with starting term 10 and common difference -2. This means we add -2 to each term to get the next one (same as subtracting 2 from each term). This common difference is directly connected to the -2 from the recursive rule f(n+1) = f(n)-2
Whatever the nth term f(n) is, we subtract off 2 to get f(n)-2 to get the f(n+1) term, which is right after the nth term.
Answer:
Step-by-step explanation:
f(1)=10
n=1
f(1+1)=f(1)-2
f(2)=10-2=8
n=2
f(2+1)=f(2)-2
f(3)=8-2=6
n=3
f(3+1)=f(3)-2
f(4)=6-2=4

Draw a graph of the linear equations x – 4y + 10 = 0 and x + 4y – 10 = 0. Find the coordinates of the vertices of the triangle formed by these lines along with the X-axis
Answers
Step-by-step explanation:
x-14y=0
x=0/14y
x=14y
14y
The second equation crosses the x axis at x + 4 x 0 - 10 = 0 => x = +10
Adding the equations together gives 2x = 0 => x = 0
0 + 4y - 10 = 0 => 4y = 10 => y = 2.5
The vertices of the triangle formed by the two lines and the x axis are (-10, 0) (10, 0) and (0, 2.5)

What is the area of the top of the installed countertop, to the nearest square foot?
Answer:
19 square foot
Step-by-step explanation:
A countertop for a kitchen is modeled with the dimensions shown below. An 18-inch by 21 inch rectangle will be removed for the sink. What is the area of the top of the installed countertop to the nearest square foot.
Convert from inches to feet
18 inches
1 inch = 0.0833 feet
18 inch = x
Cross Mulitiply
x = 18 × 0.0833 feet
x = 1.5 feet
21 inches
1 inch = 0.0833 feet
21 inch = x
Cross Mulitiply
x = 21 × 0.0833 feet
x = 1.75 feet
Area 1 = 2 ft × 8 ft = 16 ft²
Area 2 = 2 ft × 3 ft = 6 ft²
Area of a sink = Length × Width
= 1.5 ft × 1.75 ft
= 2.625 square feet
Area 1 - Area of sink
= 16 ft² - 2.625 ft²
= 13.375 ft²
Area of the top installed part =
Area 2 + 13.375 ft²
= 6 ft² + 13.375 ft²
= 19.375 ft²
Approximately ≈ 19 ft²

the result is "subtract 9"
7. same logic as "6" result "subtract 53"
8.
Step-by-step explanation:
Step-by-step explanation:
A typically addition equation is
[tex]x +y = z[/tex]
where x and y is the addends and z is the sum.
Addends both play a role in what the sum will be and they are interchangble.
A addition table have rows and columns. If we move right or down, our sum will increase. If we move left or up, our sum will decrease.
Now let answer the question.
6. If we move the up one row( which is horinzontial), our sum will decrease by 1 then if we right one column our sum will increase by 1. So this means each value will stay the same.
7. If we move up 5 rows, our sum will decrease by 5. If we move to left 3 columns, our sum will increase by 3. So all of our values will decrease by 2.
8. Write a 10 by 10 addition table.Highlight a number in any row. To add 5 to the number, either move right 5 columns or down 5 rowsTo subtract 9, either move left 9 columns or up 9 columns.The number should be 4 less than you choose.
Line segment EG is partitioned by point F in the ratio 1:3. Point E is at E (0, 4), and point F is at (1, 3). What are the coordinates of point G? (−1, 5) (2, 2) (3, 1) (4, 0)
Answers
Answer:
(4,0)
Step-by-step explanation:
Line segment EG is partitioned by point F in the ratio 1:3.
This means that:
[tex]F - E = \frac{1}{4}(G - E)[/tex]
We use this equation to find both the x-coordinate and the y-coordinate of point G.
x-coordinate:
x-coordinate of E: 0
x-coordinate of F: 1
x-coordinate of G: x
Then
[tex]F - E = \frac{1}{4}(G - E)[/tex]
[tex]1 - 0 = \frac{1}{4}(x - 0)[/tex]
[tex]1 = \frac{x}{4}[/tex]
[tex]x = 4[/tex]
y-coordinate:
y-coordinate of E: 4
y-coordinate of F: 3
y-coordinate of G: y
Then
[tex]F - E = \frac{1}{4}(G - E)[/tex]
[tex]3 - 4 = \frac{1}{4}(y - 4)[/tex]
[tex]-1 = \frac{y-4}{4}[/tex]
[tex]y - 4 = -4[/tex]
[tex]y = 0[/tex]
What are the coordinates of point G?
x = 4, y = 0, so (4,0).
