Answer:
There are 280 dimes
Step-by-step explanation:
A nickel is worth 5 cents while a dime is worth 10 cents
Let n be number of nickel
d the number of dimes
n + d = 39
Secondly
$39 is same as 3900 cents
So we have;
10d + 5n = 3900
From first equation;
n = 500-d
Put this in second equation;
10d + 5(500-d) = 3900
10d + 2500-5d = 3900
5d = 3900-2500
5d = 1400
d = 1400/5
d = 280
Ian has 3/4 of an hour to work on math problems before he leaves for track practice each problem takes 1/12 of an hour how many problems will ian be able to finish before leaving
Answer:
9
Step-by-step explanation:
Since Ian has 3/4 of an hour that is 45 minutes left till practice and it takes 5 minutes per question so he will have 9 questions finished
9514 1404 393
Answer:
9 problems
Step-by-step explanation:
The number can be found by dividing the time by the rate.
(3/4 h)/(1/12 problems/h) = (9/12)/(1/12) problems = 9/1 problems
= 9 problems
Ian can finish 9 problems before leaving.
43+9=10+42 and 10+42=52, then 43+9

Junior's brother is 1\dfrac121 2 1 1, start fraction, 1, divided by, 2, end fraction meters tall. Junior is 1\dfrac151 5 1 1, start fraction, 1, divided by, 5, end fraction of his brother's height.
Answer:
1 4/5 meters
Step-by-step explanation:
Juniors brother = 1 1/2 meters tall
Junior is 1 1/5 of his brother height
Junior = 1 1/5 of 1 1/2
= 6/5 × 3/2
= 6 * 3 / 5 * 2
= 18/10
= 1 8/10
= 1 4/5 meters
Junior is 1 4/5 meters tall

Please help!! If correct, get brainliest!
Answer:
a) <DXC and < CXB are complementary angles
b) Supplementary angles
<AXB and <DXB
<AXC and DXC
Step-by-step explanation:
Complementary angles: Two angles are complementary angles if their sum equals 90°
Supplementary angles: Two angles are Supplementary angles if their sum equals 180°
a) Name a pair of complementary angles
So, <DXC and < CXB are complementary angles
b) Name two Supplementary angles pair
<AXB and <DXB (their sum equals 180°)
<AXC and DXC ((their sum equals 180°))

Identify the slope and y-intercept: y = ¼x - ⅓
if you could please help me right not I would really appreciate it.
Answer:
Slope: ¼, y-intercept: -⅓
Step-by-step explanation:
We know that slope-intercept is y=mx+b. We also know that m is the slope, b is the y intercept, y is y, and x is x. As we can see, the equation is y = ¼x - ⅓. Since it is minus ⅓, not plus ⅓, that means the y-intercept is negative. Now we know that the y-intercept is -⅓. Now, let's identify the slope. The slope is ¼, because it is the number next to x (y=mx+b). Now that we know this, we have our answer! The slope is ¼, and the y-intercept is -⅓! I hope this helps!

help asap! Identify the function shown in this graph.
Answer:
A
Step-by-step explanation:
Using the formula y=mx+b we see the b (the y intercept) is at -1. Only answer choice A and B have a y intercept at -1. Now we check which one of those will correspond with the negative slope. A is negative and B is positive --> A is the correct answer choice.

Irena sells ice cream
One day she sells 80 ice creams,
the next day she sells 108 ice creams.
Work out the percentage increase in the number of ice creams she sells.
Answer:
35%
Step-by-step explanation:
Change/original x 100
The change between 80 and 108 is 108-80 = 28.
28/80 x 100 (80 is our original number of ice cream cones that she sold).
.35 x 100 = 35%
Answer:
The answer is 35%.

In the past, the mean running time for a certain type of flashlight battery has been 9.7 hours. The manufacturer has introduced a change in the production method and wants to perform a hypothesis test to determine whether the mean running time has increased as a result. The hypotheses are: H 0: μ = 9.7 hours H a: μ > 9.7 hours where μ is the mean running time of the new batteries . Explain the meaning of a Type I error.
Answer:
Step-by-step explanation:
From the information given:
[tex]\mathbf{H_o: \mu = 9.7 \ hours}[/tex]
[tex]\mathbf{H_1: \mu > 9.7 \ hours}[/tex]
The type 1 error is rejecting [tex]\mathbf{H_o}[/tex] when
The meaning of Type 1 error is rejecting the claim that the mean running time is 9.7 hours when actually the mean running time is greater than 9. 7 hour.

Answer:
A) y = -1/2x + 2
Step-by-step explanation:
The line is negative, so you will have a negative slope
The line is crossing the y- axis at 2 so the y- intercept is 2.
Now do rise over run or rise/run
The lines rise is 2 and the run is 4
2/4 = 1/2 and since the line is negative the slope is negative -1/2
y = -1/2x + 2
Hope this helps ya!!

A migrating bird flies 42 miles in 3 hours. How many miles does it fly in 5 hours?
Answer:
70 miles.
Step-by-step explanation:
In this question we are given the speed of the migrating bird. If we remember the definition of speed we will remember that speed is distance the object/body traveled, divided by the time it took the object/body to travel this distance.
Solution:
Firstly we need to find out what distance will the bird travel in 1 hour. We can easily do that science we know the distance it travels in 3 hours. So we just use the property of a fraction that states that if we multiply or divide the denominator and the numerator by the same number we will get a fraction of the same value but written a bit differently. So we divide the numerator and the denominator by 3 and get
[tex]\frac{42 miles}{3 hours}[/tex] = [tex]\frac{14 miles}{1hour}[/tex]
Now we know what distance the bird travels in one hour so we can easily figure how much the bird will travel in 5 hours by multiplying the numerator and the denominator by 5. So we do...
[tex]\frac{14 miles}{1 hour}[/tex] = [tex]\frac{70 miles}{5 hours}[/tex]
And we get that the bird will travel 70 miles in 5 hours.
