Answer:
A is the correct answer
Answer:
B
Step-by-step explanation:
The first number should represent the lawns, and the second should represent the money he makes on each lawn.
A is incorrect because the numbers are swapped; Ryan does not earn one dollar for mowing 20 lawns.
C is wrong because if Ryan mows zero lawns, how can he make money. Although the multiplication is correct, it does not start at zero.
D is wrong because it is counting the price up by ten instead of adding 20.
B is right because every lawn is 20 more dollars, and that is what is shown.
What is the current value for a future sum of money called?
A. Current value
B. Present value
C. Future value

Answer:
[tex](21in,30in)=>210in^2[/tex]
[tex](15in,18in)=>90in^2[/tex]
[tex](15in,30in)=>150in^2[/tex]
Step-by-step explanation:
Required
Match the expressions on the left with the right
(a) 21 in by 15 in
Calculate area
[tex]Area = 21in * 15in[/tex]
[tex]Area = 315in^2[/tex]
Multiply by [tex]1/3[/tex]
[tex]1-third = 315in^2 * \frac{1}{3}[/tex]
[tex]1-third = 105in^2[/tex]
Hence:
[tex](21in,15in)=>105in^2[/tex]
(b) 21 in by 30 in
Calculate area
[tex]Area = 21in * 30in[/tex]
[tex]Area = 630in^2[/tex]
Multiply by [tex]1/3[/tex]
[tex]1-third = 630in^2 * \frac{1}{3}[/tex]
[tex]1-third = 210in^2[/tex]
Hence:
[tex](21in,30in)=>210in^2[/tex]
(c) 15 in by 18 in
Calculate area
[tex]Area = 15in * 18in[/tex]
[tex]Area = 270in^2[/tex]
Multiply by [tex]1/3[/tex]
[tex]1-third = 270in^2 * \frac{1}{3}[/tex]
[tex]1-third = 90in^2[/tex]
Hence:
[tex](15in,18in)=>90in^2[/tex]
(d) 15 in by 30 in
Calculate area
[tex]Area = 15in * 30in[/tex]
[tex]Area = 450in^2[/tex]
Multiply by [tex]1/3[/tex]
[tex]1-third = 450in^2 * \frac{1}{3}[/tex]
[tex]1-third = 150in^2[/tex]
Hence:
[tex](15in,30in)=>150in^2[/tex]
the answer is NOT.. C. please help .
Answer:
Option B
Step-by-step explanation:
First term of the given arithmetic sequence 'a' = -3
Common difference in each successive term 'd' = -8 - (-3)
d = -5
Explicit formula for an arithmetic sequence will be,
[tex]A_n=a+(n-1)d[/tex]
Here, n = number of term
[tex]A_n[/tex] = nth term of the sequence
[tex]A_n=(-3)+(n-1)(-5)[/tex]
For n = 23,
[tex]A_{23}[/tex] = -3 + (23 - 1)(-5)
= -3 - 110
= -113
Option B is the answer.
x=3y−5 2x+12y=-4 please solve the system of equations and show your work
sub x = 3y - 5 into equation 2
2(3y - 5) + 12y = -4
6y - 10 + 12y + 4 = 0
18y - 6 = 0
18y = 6
y = 6/18
y = 1/3
sub y = 1/3 into equation 1
x = 3(1/3) - 5
x = 1 - 5
x = -4

Which is the graph of the line given below? *
y=2/3x-5
To make this graph the first step is to look at the slope-intercept form
- we see that 2/3 is the slope and -5 is the y-intercept (the point on the y-axis)
So, now you can find the y-intercept on the graph (-5) and make a dot there
Next, move right 3 and up 2 and repeat until you have enough points to make a line :)
graph below- hope this helps :)
Shiro and Tatiana weighed some pebbles in
science class. They made a line plot to display
their data. Use the line plot to answer
Answer:
The answer is below
Step-by-step explanation:
a) Of the pebbles that were measured, which weight occurs the least?
Soln.: From the line plot, we can see that 3 ounce occurred once, 3 1/2 ounce occurred 4 times, 4 ounce occurred 3 times, 4 1/2 ounce occurred 5 times, 5 ounce occurred 2 times, 5 1/2 ounce occurred 3 times, 6 ounce occurred 2 times.
Therefore 3 ounce occurred the least.
b) What is the total weight of the pebbles represented by the data?
Soln.: The total weight is:
Total weight = (3*1) + (3 1/2 * 4) + (4 * 3) + (4 1/2 * 5) + (5 * 2) + (5 1/2 * 3) + (6 * 2) = 90 ounce
c) Is there an outlier in the data set? If so what number is the outlier?
Soln.: There is no outlier in the data set because all the data are close to each other.

Carbon 14 (14C) dating assumes that the carbon dioxide on Earth today has the same radioactive content as it did centuries ago. If this is true, the amount of 14C absorbed by a tree that grew several centuries ago should be the same as the amount of 14C absorbed by a tree growing today. A piece of ancient charcoal contains only 12% as much radioactive carbon as a piece of modern charcoal. How long ago was the tree burned to make the ancient charcoal given that the half-life of 14C is 5700 years? (Round your answer to the nearest whole number.)

5x−9≥11
Select one:
x≤−4
x≥4
x≤4
x≥−4
Answer:
[tex]x \geqslant 4[/tex]
Step-by-step explanation:
1) Add 9 to both sides.
[tex]5x \geqslant 11 + 9[/tex]
2) Simplify 11 + 9 to 20.
[tex]5x \geqslant 20[/tex]
3) Divide both sides by 5.
[tex]x \geqslant \frac{20}{5} [/tex]
4) Simplify 20/5 to 4.
[tex]x \geqslant 4[/tex]
Thus, the answer is Option B.
5x−9 ≥ 11
5x ≥ 11 + 9
5x ≥ 20
x ≥ 20/5
x ≥ 4

Answer:
-8, 36, -5Step-by-step explanation:
This sort of pattern is used in the factoring of trinomials. Typically, the top quadrant holds the product you're trying to factor. The bottom quadrant holds the sum of the factors. The factors appear on the left and right in no particular order.
__
1) You're looking for factors of -24 that have a sum of -5. It can be useful to simply list the factor pairs. Since you want a negative sum, you may want to start with the most negative factors and work up from there.
-24 = (-24)(1) = (-12)(2) = (-8)(3) = (-6)(4)
The sums of these factor pairs are -23, -10, -5, -2. Obviously, the pair we're interested in is the one with a sum of -5: (-8) +(3).
So, the left- and right-quadrants are filled with -8 and 3.
Blank 1 = -8
Blank 2 = 3
__
2) You are given the factors, so all you need to do is form the product and sum.
Blank 1 = (-3)(-2) = 6
Blank 2 = (-3) +(-2) = -5
_____
Additional comment
Any sort of factoring is much easier to do if you have memorized your multiplication tables, preferably through 12×12. It is also helpful if you're familiar with divisibility rules—at least for single-digit numbers. I've seen college students struggle trying to do factoring using a calculator. It's not pretty. Many folks learn their times tables up to 10×10 by the end of 3rd grade.
Answer:
Blank 1: -8
Blank 2: 3
Step-by-step explanation:
Sorry if i'm late on this but it is the same X method concept. -8 and 3 add up to get -5, and they multiply to get -24

Find the sum of deviation of all observations of the data 5, 8, 10, 15, 22 from their mean.
Answer:
the sum of deviation of all observations of the data 5, 8, 10, 15, 22 from their mean. =26
Step-by-step explanation:
Mean=sum of observation/ No. of observation
={5+8+ 10+ 15 + 22}/5
=60/5=12
Sum of deviations
= |5- 12| + |8 – 12| + |10- 12| + |15- 12| + |22-12|
= 7+4+2+ 3+ 10
= 26

Answer: x4
Step-by-step explanation:
Solve the system of equations
4x+3y=16
y=x+3
X=
Y=
First you substitute.
[tex]4x+3(x+3)=16\\4x+3x+9=16\\7x=7\\x=1\\y=4[/tex]
Answer:
x = 1 and y = 4
Step-by-step explanation:
Because y = x + 3 we can substitute 3y with 3(x + 3)
4x + 3(x + 3) = 16
4x + 3x + 9 = 16
7x + 9 = 16
7x + 9 - 9 = 16 - 9
7x = 16 - 9
7x = 7
7x ÷ 7 = 7 ÷ 7
x = 7 ÷ 7
x = 1
Since y = x + 3 and x = 1 y = 4.
1 + 3 = 4
x = 1 and y = 4
Check:
x = 1 and y = 4
1 x 4 + 3 x 4 = 16
4 + 12 = 16
whats the sum of 1/6+1/3+1/6
Answer:
2/3
Step-by-step explanation:
2/6 is equal to 1/3 so I added both 1/6's together first and then added the resulting 1/3 with the other 1/3 and got 2/3
you could also convert the 1/3 to 2/6 and add all the sixths together to get 4/6 which is equal to 2/3
hope this helps chu<3
Answer:
4/6.
Step-by-step explanation:
1/6+1/6=2/6 1/3 converts into 2/6 so 2/6+2/6=4/6

You roll a die. What's the theoretical probability of rolling a number greater than 2?
Answer: if the dice is six sided you have 4 chances to roll a higher number
Step-by-step explanation:
Answer:
3 in 36
Step-by-step explanation:
assuming a fair die you have three possible odd numbers out of six total possible outcomes so the probability is 0. the prob ability of getting an even number greater than 2 when rolling standard die must be 1/3. The probability of doing both, on two rolls, is 3 in 36, or 1 in 12.
