Answer:
Lina should make $471.75 a month.
Step-by-step explanation:
If Lina makes $9.25 an hour and she works for 15 hours a week then you multiply those two numbers together. The resulting number is $555. Then you'll multiply that by .15 to find 15% of that number which is 83.25. After, you'll subtract that from $555, which gives you $471.75.

at point (0,2) can be reflected across the x-axis PLEASE HELP 50 POINTS true pr false
Answer:
Please check the explanation.
Step-by-step explanation:
When a point P(x, y) is reflected across the x-axis, all we need to do is to reverse the sign value of the y-coordinate of any given point while the x-value remains the same.
Thus,
The rule to reflect over the x-axis is:
P(x, y) → P'(x, -y)
In our case, the point, let's say A(0, 2), is reflected across the x-axis. Thus, the coordinates of A' will be:
P(x, y) → P'(x, -y)
A(0, 2) → A'(0, -2)
So, YES! point A(0,2) can be reflected across the x-axis and the coordinates of A' will be: A'(0, -2).

what is the number that is two more than one-tenth of one-fifth of one-tenth of 2,000
Answer:
6
Step-by-step explanation:
2 + (1/10)(1/5)(1/10)2000 = 2 + (1/500)(2000) = 2 + 4 = 6
The number that is two more than one-tenth of one-fifth of one-tenth of 2,000 will be 6.
What are the ratio and proportion?The ratio is the division of two numbers while multiplication is an operation in mathematics to multiply two or more values to get a multiplied number.
Proportion is the relation of a variable with another. It could be direct or inverse.
The one-tenth of x = (1/10)x similarly
one-tenth of one-fifth of one-tenth = (1/10)(1/5)(1/10)
So one-tenth of one-fifth of one-tenth of 2,000 = (1/10)(1/5)(1/10) ×2000
⇒ 2000/500 = 4 Now the question is saying 2 more hence
⇒ 4 + 2 = 6 hence six will be the correct answer.

The polygons are similar. Find the values of
the variables. Write an equation and solve,
showing ALL the work.
Answer:
x = 12, y = 8
Step-by-step explanation:
Since we know that the two triangles are similar that means we can find the ratio. The larger triangle is two times larger, we can find that out using 7/3.5 = 2. That means x + 4 = 2y and 3y = 2x. We can solve for y using substitution. We can double the first equation. 2x + 8 = 4y. We know that 2x = 3y so we can plug that in. 3y + 8 = 4y. Solving for y, gets us y = 8. Now we can plug that into any of the prior equations. I'll use 3y = 2x. 3(8) = 2x. 24 = 2x. Divide both sides by 2. x = 12.

A) 3x - 5 ≥ -14
B) 3x - 5 ≤ -14
C) 3x - 5 > -14
D) 3x - 5 < -14
Answer:
D
Step-by-step explanation:
We can work backwards.
First, notice that we have an open circle. So, we do not have "or equal to." So, we can ignore A and B.
Our final answer is all values less than -3. So:
[tex]x<-3[/tex]
We can multiply both sides by 3:
[tex]3x<-9[/tex]
And then subtract 5 from both sides:
[tex]3x-5<-14[/tex]
So, the answer that matches this will be D.
Instead of working backwards, you can also just solve each inequality. Since we have an open circle, we only need to solve C and D. If we solve C, we get x > -3, and if we solve D, we get x < -3 (as desired). So, D matches the graph shown.

The time,
T
(seconds), it takes for a pot of water to boil is proportional to the amount,
A
(litres), of water.
It takes 180 seconds to boil 2.8 litres of water.
Work out how long it takes (to the nearest second) to boil 2.2 litres.
Answer:
The time it takes to boil 2.2 litres of water is approximately 141 seconds
Step-by-step explanation:
The given parameters are;
The relationship of the variables, T and A is a proportional, therefore, we have;
T ∝ A, or T/A = k = Constant of proportionality
The time it takes to boil 2.8 liters of water = 180 seconds
∴ When A = 2.8 litres, T = 180 seconds, from which we have;
k = T/A = 180 s/(2.8 L) = 450/7 s/L
k = 450/7 s/L
When A = 2.2 litres, we have;
T/A = k
∴ T = k × A
Plugging in the value for both 'k', and 'A' when A = 2.2 litres, gives;
T = k × A = 450/7 s/L × 2.2 L = 990/7 s = 141.[tex]\overline{428571}[/tex] s
The time it takes to boil 2.2 litres of water, given a direct proportionality relation is, T = 141.[tex]\overline{428571}[/tex] seconds ≈ 141 seconds given to the nearest second.

In which number does the digit 3 have a value that is 10 times as great as the value of the digit 3 in 143,728?
Complete question :
In which number does the digit 3 have a value that is 10 times as great as the value of the digit 3 in 143,728? 137,982 142,398 292,389 392,097
Answer:
137,982
Step-by-step explanation:
The value of digit 3 in 143, 728
3 in 143,728 is in the 1000 thousand place, hence, digit 3 has a value of :
3 * 1000 = 3000
Therefore, 10 times the value of digit 3 will be :
3000 * 10 = 30000
Feom the options given, we obtain the option where 3 has a value of 30000 if the number is expressed in expanded form:
The answer is 137,982
3 here is in the 10 thousand place = 3 * 10,000 =. 30,000
earth's equator has a diamter of 7926.4 miles. which equation can be used to find the circumference of earth at the equator?
Answer:
To find the circumference you need to use C= 2πr but since you started with the diameter you need to divide it by 2 and you will get 3963.2. After you get the radius use the formula C= 2πr and you will get 24901.52
The equation would be written as 2 x π x 3963.2 = 24901.52

replaces the crayon in the box. If she selects a crayon 30 times, how many
times do you predict she will select a blue crayon?

07
0 10
08
Answer: i’m really not sure about this one but i think eight
Step-by-step explanation: if you calculate the probability of drawing a blue crayon you should get 16/60. if you’re drawing thirty times then multiply 16/60 by thirty and you get eight. sorry if this is incorrect hope this helped :D
Question 4 A triangle has two sides that are 8 cm and 13 cm. What could be the length of the triangle's third side? Select three that apply. А 5 cm B 10 cm С 17 cm D 20 cm E 21 cm F 24 cm
know what is the third side length
the difference between the 2 other sides < the greatest side of triangle < the sum of 2 other sides
so here the answers here could be ( 10- 17 - 20)
10-8 < 13 < 10+8
13-8 < 17 < 13+8
13-8 < 20 < 13+8

x-7=15
Answer:
x = 22
Step-by-step explanation:
x = 7 + 15
x = 22
Answer:
x = 22
Step-by-step explanation:
1x - 7 = 15
1x = 15 + 7
1x = 22 (divide both sides by the first number/1 to get x)
1x/1 = 22/1
x = 22

Jeff can type 110 words in 2 3/4 minutes. How many words can he type
in 4 1/4 minutes? *
Answer:
680
Step-by-step explanation:
What we should know is how many words he can type in 1/4 minutes. We can do 110 divided by 2.75 which is 40. 40 is the number of words he can type in 1/4 minutes. Now multiply this 17 (4 1/4 = 17/4) and you get 680. I believe he can type 680 words in 4 1/2 minutes. (Make sure my answer is correct)
