Answer:
Jordan age = 31 yearsAnna age = 19 yearsStep-by-step explanation:
let Jordan age be X & Anna age be Y
so,
Jordan is 12 years older than Anna.
x = y + 12 ......... (1)
The sum of their ages is 50.
x + y = 50 ........ (2)
putting value of x from (1) into (2)
x + y = 50
(y + 12) + y = 50
2y + 12 = 50
2y = 50 - 12
2y = 38
y = 38÷2
y = 19
putting value of y in (2)
x + y = 50
x + 19 = 50
x = 50 - 19
x = 31
so,
Jordan age = 31 years
Anna age = 19 years
A corn field has an area of 28.6 acres. It requires about 15,000,000 gallons of water. About how many gallons of water per acre is that?
Answer:
500,000
Step-by-step explanation:
so here's what's up, because it says about we can round 28.6 acres up to about 30. and there is 15,000,000 water every time. its a rather simple question. because all of the water needs to be divided equally, we must divide 15,000,000 by 30. and that makes a total of 500,000. so your answer is 500,000. but be carful because sometimes you must do the opposite.
Answer:
524,475.5 gallons
Step-by-step explanation:
15,000,000 / 28.6 = 524,475.5 gallons
What is the slope of the line
Answer:
The slope is 2!
Step-by-step explanation:
To find the slope of a line, you must first find two points that are EXACTLY on the grid.
Two points I picked are (-1, -2) and (0,0).
Now count how many points the numbers are far from each other up and down. So, starting from (-1,-2) to (0,0), the points are two points away from each other vertically (on the y-axis)
Now find how far they are on the x-axis
Once again I counted and they are 1 point away from each other horizontally.
Now you need to turn these two points into a fraction.
Slopes are rise/run or y/x
So:
The slope is 2/1.
Also, the slope is positive as the line ascends (goes up).
If the line were negative or going down, the slope would be negative, but the line is positive.
So, the answer is 2!

Suppose the function h(x) = 2x - 9 is translated up 5 units to become a new function,
i(x)
What's the equation of the new function?
A) i(x) = 2x - 4
B) i(x) = 77-9
C) i(x)= 2x- 14
D) i(x)= 7x- 4
Answer:
B
Step-by-step explanation:
Given that the function h(x) = 2x-9 is translated up 5 united to become a new function, i(x)
To find: Equation of new function
The graph of a function can be moved up, down, left, or right by adding to or subtracting from the output or the input.
Adding to the output of a function moves the graph up
Therefore,
Given function is:
h(x) = 2x - 9
Translated up by 5 units
Therefore, new function is:
i(x) = h(x) + 5
i(x) = 2x - 9 + 5
i(x) = 2x - 4
Thus Option B is correct

A parallelogram has a base of ⅝ centimeters and a height of 16 centimeters. What is the area of the parallelogram?
Answer:
10
Step-by-step explanation:
1. –5 + (–1) + 7 PLEASE STEP BY STEP
2. 19 + (–3) + 6
Answer:
1) -5+(-1)+7
-6+7
=1
2) 19+(-3)+6
16+6
=22
Answer:
1: 1
2: 22
Step-by-step explanation:
1 ) -5 + (-1) is -6, because they both have the same sign.
-6+7} when there is a negative and a postive, put the postive in front
so it will look like this 7-6 which is 1
2) 19+(-3) is basically 19-3, which is 16, and 16+6=22
Extra note:
when you see n+(-n), always remove the + sign and subtract
when you see -n+n, always switch the roles of the two
when you see -n+-n, remove the - sign and add it back later
when you see -n-n, think of -n+n
I hope these helps :)
The equation y=4.2x could represent a variety of situations. Write your own description of a situation represented by this equation. Decide what quantities x and y represent in your situation.
Answer:
The solution is given below:
Step-by-step explanation:
Given that
The equation is 4.2x
It could present the total price for the no of goods
Here we take an example
The price per chips is $4.2
And, the number of chips purchased be x
And, the total price would be y
So if 5 chips were purchased, so the total price would be
y = $4.2 (5)
= $21
hence, the above represent the description

y int = (0,4)
Step-by-step explanation:
x intercept y=0
6x+0=4
6x=4
x=4/6
x=2/3
(2/3,0)
y intercept x=0
6(0)+y=4
y=4
(0,4)
Answer:
(0,4) and ([tex]\frac{2}{3}[/tex], 0)
Step-by-step explanation:
6(0) + y = 4
y = 4
(0,4)
6x + 0 = 4
6x = 4
x = [tex]\frac{2}{3}[/tex]
([tex]\frac{2}{3}[/tex], 0)

Vhen flipping a coin, what is the probability of landings
meads and then heads again?
0.25% chance or 1/4th.
You have a 50/50 chance of getting heads or tails on a throw. .50 for each.
If you do get heads, there's the same chance of getting another heads.
Multiply the .50% chance of getting heads by .50 again, and you end up with a 0.25% chance total of getting heads twice in a row.

Angie is correct about both inverses.
Angie is correct about neither inverse.
Angie is correct about the additive inverse only.
Angie is correct about the multiplicative inverse only.
In the Exercises below, find the scale factor. Then list all pairs of congruent angles and write the ratios of the corresponding side lengths in a statement of proportionality.
Answer:
8) scale factor: 3
angles Q & L, S & N, r & M
sides 10 x 3 = 30, 6 x 3 = 18, 13 x 3 = 39
9) scale factor: 0.4
angles B & F, C & G, D & H, A & E
sides 9 x 0.4 = 3.6, 7.5 x 0.4 = 3, 10 x 0.4 = 4, 12 x 0.4 = 4.8
The scale factor for part (8) is 3, angles Q & L, S & N, R & M, for part (9) is 0.4 and angles of pair are congruent B & F, C & G, D & H, A & E
What is a scale factor?The ratio among comparable dimensions of an object and a model with that object, known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
8)
Scale factor for the triangle LMN:
Let's suppose the scale factor is x
3x= 30 ⇒ x = 3
6x= 18 ⇒ x = 3
13x=39 ⇒ x = 3
So the scale factor is 3
Angles Q & L, S & N, R & M
39/13 = 30/10 = 18/6 = 3
9)
Scale factor for the triangle LMN:
Let's suppose the scale factor is y
12y= 4.8 ⇒ x = 0.4
9x= 3.6 ⇒ x = 0.4
10x=4 ⇒ x = 0.4
So the scale factor is 0.4
Angles B & F, C & G, D & H, A & E
4.8/12 = 3.6/9 = 4/10 = 0.4
Thus, the scale factor for part (8) is 3, angles Q & L, S & N, R & M, for part (9) is 0.4 and angles of pair are congruent B & F, C & G, D & H, A & E
