Which equation represents a line which is parallel to the line 2y-5x=-162y−5x=−16?
Answer:
Step-by-step explanation:
For two lines to be parallel to each other, they must have the same slope.
The standard form of expressing equation of a line is y = mx+c
m is the slope.
First let us get the slope of the given line
Given the line 2y-5x = -16
Rerwrite in standard form;
2y-5x = -16
2y = 5x-16
Divide through by 2;
2y/2 = 5x/2 -16/2
y = 5x/2 - 8
The slope of the line is 5/2
Since we are not given options, we can as well say that the equation of the line parallel to this line must have a slope of 5/2 no matter the intercept. Example of such line are;
y = 5/2 x + 2
Set up a proportion for the problem.
11 is what percent of 33 ?
Answer:
its 3 percent
Step-by-step explanation:
The sum of 13 and twice a number and is it linear
Answer:
Step-by-step explanation:
The number is already defined as ' h '. "Twice" means times by 2. So, 13 and twice 'h' are being added together. Here 13 and h are to be added, and the answer is doubled.
A rectangular pool has a length of 200 ft. You're building a model. Using a scale
factor of 1725, what is the scale length of your model? *
Answer:
1.4 inches.
Step-by-step explanation:
Given that the length of the pool = 200 ft.
Scale factor = 1725.
As,
[tex]\text{Scale factor }=\frac{\text{Original length}}{\text{Scaled length}}[/tex]
So,
[tex]\text{Scaled length} = \frac{\text{Original length}}{\text{Scale factor}}[/tex]
By using the given values, we have
{Scaled length} [tex]= \frac{200}{1725} ft.=0.116 ft.[/tex]
As 1 foot = 12 inch,
So, scaled length = 0.116 x 12 = 1.4 inches.
Hence, the scale length of the model = 1.4 inches.
mrs Moore worked 42 hours and 35 minutes last week. How many hours and minutes did she average in each of the five days?
Answer:
6.08333333 hours
Step-by-step explanation:
((42 hours) + (35 minutes)) / 7 = 6.08333333 hours
hope this helps LOL :)
Answer:
511 min or 8 hrs and 52 min
Step-by-step explanation:
first you need a common subject so convert 42 hours into min, which is 2,520 then add the 35 which gives you 2,555 total.
then divide by 5 which gives you the adverage of 511 min
convert answer into hours which is about 8 hours and 52 min rounding up

Help plzzzz will give brainliest
Answer:
It's positive.
Step-by-step explanation:
There are many reasons.... but one of the obvious ones is that it would've shown negative, correct?
Choose True or False for each statement.
Column A
1.
If the distance from 0 to x on a number line is equal to 2, then -2 + X = 0.:
If the distance from 0 to x on a number line is equal to 2, then -2 + X = 0.
2.
If the distance from 0 to x on a number line is less than 2, then -2 + X = is negative.:
If the distance from 0 to x on a number line is less than 2, then -2 + X = is negative.
3.
If the distance from 0 to x on a number line is greater than 2, the -2 + X is positive.:
If the distance from 0 to x on a number line is greater than 2, the -2 + X is positive.
4.
If the distance from 0 to x on a number line is greater than 0, then -2 + X is positive.:
If the distance from 0 to x on a number line is greater than 0, then -2 + X is positive.
8. A substance has a half life of 2.347 minutes.
a. If the initial amount of the substance was 110.4 grams, how many half-lives will have passed
before the substance decays to 6.9 grams.
b. What is the total time of the decay?
Answer:
a.) 4 half lives have passed
b) 9.388 minutes
Step-by-step explanation:
Formula for exponential growth / decay is given as:
[tex]A=A_0b^{\frac{t}{c}}[/tex]
Where [tex]A[/tex] is the final population
[tex]A_0[/tex] is the initial population
[tex]b[/tex] is the growth factor
[tex]c[/tex] is the time taken for the growth 'b'
[tex]t[/tex] is the amount of time
Here, we are given that:
[tex]A[/tex] = 6. 9 grams
[tex]A_0[/tex] = 110.4 grams
[tex]b = \dfrac{1}{2}[/tex]
[tex]c = 2.347[/tex] min
To find:
a.) Number of half lives taken for the decay.
b.) Total time in the decay.
Solution:
a.) Number of half lives taken for the decay is nothing but equal to [tex]\frac{t}{c}[/tex].
Putting the values in the formula, we get:
[tex]6.9=110.4\times \frac{1}2^{\frac{t}{c}}\\\Rightarrow 6.9=110.4\times 0.5^{\frac{t}{c}}\\\Rightarrow 0.0625=0.5^{\frac{t}{c}}\\\Rightarrow \dfrac{t}{c} =4[/tex]
Therefore, the answer is:
4 half lives have passed.
b.) Total time of decay. We have to find the value of [tex]t[/tex] here.
From answer of part a.):
[tex]\dfrac{t}{c} =4\\\Rightarrow \dfrac{t}{2.347} =4\\\Rightarrow t =\bold{9.388\ min}[/tex]

Please answer the 2 questions if you can? (This is my math from 8th grade)
Answer:
8.no answer A. x=8
Step-by-step explanation:
10.no answer B. x= -3
Answer:
8. (A) x = 8 , 10. (C.) x = 3
Step-by-step explanation:
Number 8 you could do 75 - 35 = 40
so what can you multiply 5 by (x) to get 40? you would multiply 5 by 8 or (x) and get 40
then add 35 + 40 to get 75 degrees which is the parallel angle to the other 75 degrees.
Number 10 you just want to get them to the same number.
so you would do ( 97 - 3 ) to get the ANSWER 87.
so x = 3

Answer:
96 loaves
Step-by-step explanation:
6 hours is 360 minutes. Divide that by 45 min equals 8. If he can bake 12 every 45 min, then he can bake 8 x 12 loaves in 6 hours or 96 loaves.
Answer:
A, 96 loaves of bread
Step-by-step explanation:
So first off, since the rate is in minutes and not hours, you would first find how many minutes are in 6 hours. 60 minutes per hour multiplied by 6 hours gets you 360 minutes. You would now divide 360 by 45, and that would get you 8. You now have 8 units of 45 minutes, if that makes sense. You would now multiply 8 by 12, and get 96 loaves of bread.
The number of miles driven by a truck driver falls between 300 and 700, and follows a uniform distribution.
a. Find the probability that the truck driver goes more than 650 miles in a day.
b. Find the probability that the truck drivers goes between 400 and 650 miles in a day.
c. At least how many miles does the truck driver travel on the furthest 10% of days?
Answer:
(A) 0.125 probability
(B) 0.625 probability
(C) 660 miles
Step-by-step explanation:
The distance driven by a truck driver daily, falls between 300miles and 700miles and follows a uniform distribution.
(A) The probability that the truck driver goes more than 650 miles a day is:
[700 - 650] / [700 - 300] = 50/400 = 0.125
(B) The probability that the truck driver goes between 400 and 650 miles a day is:
[650 - 400] / [700 - 300] = 250/400 = 0.625
(C) The minimum number of miles the truck driver travels on the furthest 10% of days is given thus:
10% of 400 = 40
Subtract this from the farthest distance;
700miles - 40miles = 660miles

if the slope is -3/5 and the y intercept is 1 what is the slope intercept form of the equation of each line given the slope and y intercept
Answer:
y = -3/5x + 1
Step-by-step explanation:
The perimeter of the triangle is 350 units. Find the measure of each side (label your answers).
Answer:
125, 105, 120
Step-by-step explanation:
You would first make an equation with what you know:
x + 45 + x + 25 + x + 40 = 350.
Now, you would simplify and add like terms.
3x + 110 = 350
Now, you would subtract 110 from both sides.
3x = 240
Now, you would divide both sides by 3.
x = 80
Now that you know what x is, simply plug it in to the respective equations for all three sides.
x + 45 would become 80 + 45, and add up to 125.
x + 25 would become 80 + 25, and add up to 105.
x + 40 would become 80 + 40, and add up to 120.
To check your work, you would now add the three totals.
125 + 105 + 120 = 350.
there are 17 boxes each box holds 42. how many packets of sweets are there in total?
Answer: 714
Step-by-step explanation:
42 • 17 = 714
divide to check if it is correct
714 ÷ 42 = 17 or 714 ÷ 17 = 42
hope it helps!
Answer:
No.of sweets in one box = 42
No.of sweets in 17 boxes = 42 x 17
= 714
