A collector has 2792 coins
altogether. Half of the coins
are on display. The collector
buys more coins at an auction
so that the coins on display
are now 40% of the collection.
How many coins are bought at
the auction?
Answer:
3490 coins
Step-by-step explanation:
Given data
Total coins= 2792 coins
Half of the coins are on display
that is 50% are on display
=2792/2
=1396
let the coins bought be x
40% of x= 1396
40/100*x= 1396
0.4x= 1396
x= 1396/0.4
x=3490
Hence 3490 coins were bought
At a bake sale, the soccer team had 50 packs of cookies to sell. At the end of the sale, they had 5 packs left.
What FRACTION of the cookies were sold?
Answer:
45/50= 9/10
Step-by-step explanation:
If 5 packs were left after the sale, then 50-5=45 is the number of packs sold
Then the fraction sold would be the number of packs sold divided by the total number of packs.
45 sold/50 total

Please find the slope of (-2, 4) and (3, -5)
Answer:
The slope of the line = m = -9/5
Step-by-step explanation:
Given the points
(-2, 4)(3, -5)Determining the slope between (-2, 4) and (3, -5)
(x₁, y₁) = (-2, 4)
(x₂, y₂) = (3, -5)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [-5 - 4] / [3 - (-2)]
= [-9] / [3 + 2]
= -9/5
Thus, the slope of the line = m = -9/5
Answer:
m = -9/5
Step-by-step explanation:
Taking (-2,4) as (x1,y1), and
Taking (3,-5) as (x2,y2)
Using the slope (m) formula:
[tex]m = \frac{y2-y1}{x2-x1}[/tex]
= (-5-4)/(3-(-2))
= -9/(3+2)
= -9/5
Hence, the slope is -9/5

4) Line L has equation y = 4x - 7, and line M is parallel to line L and passes through the point (2,15). Determine the equation of line M. A) y = 4x + 7 B) y = 2x + 7 ©). y = 4x + 15 D) y = 2x + 15
Answer:
the answer is A.y=4x+7
Step-by-step explanation:
Line M is parallel to the line L, so the equation for line M isy=4x+b
Plug in the coordinates of the point (2,15) , you get:
15=4*2+b
Solve that to get b=7
Therefore the equation of line M is y=4x+7
You estimate that there will be 85 people at your party, but only 75 show up, what is the percent error of your estimate?
Answer:
Percentage error of your estimate = 13%
Step-by-step explanation:
Given
Approximate value = 85
Exact value = 75
To determine
Percentage error can be determined using the formula
Percentage Error = |Approximate Value − Exact Value| / |Exact Value| × 100%
= |85 − 75| / |75| × 100%
= 10 / 75 × 100%
= 0.1333 × 100%
= 13%
Therefore, percentage error of your estimate = 13%
