Let Monique's number of art brushes be m.
Then, since Chelsea has <span>11 times as many art brushes as Monique, Chelsea has 11m brushes.
Together they have 60 art brushes, so we write the equation:
m+11m=60.
This means that 12m=60, dividing both sides of the equation by 12 we get m=5.
Chelsea has 11m=11*5=55 brushes.
Answer: 55</span>
It is easier to add 50 to a number than 48 because 50 has a zero in it which makes an addition simpler.
48 + 34 = borrow 2 from 34 and add to 48
= 50 + 32 50 + 32 is 82
= 82
Answer:
Rounding to the nearest tenth and rounding to the nearest one hundredth.
Step-by-step explanation:
round all up or down then line up and add
12.568= 13
11.426= 11
12.324= 12
11.981= 12
12.601= 13
add the totals then you see
60.83 sames as 61
Answer:
f(t) = 4(t − 1)2 + 4; the minimum height of the roller coaster is 4 meters from the ground
Step-by-step explanation:
The function is a quadratic where t is time and f(t) is the height from the ground in meters. You can write the function f(t) = 4t2 − 8t + 8 in vertex form by completing the square. Complete the square by removing a GCF from 4t2 - 8t. Take the middle term and divide it in two. Add its square. Remember to subtract the square as well to maintain equality.
f(t) = 4t2 − 8t + 8
f(t) = 4(t2 - 2t) + 8 The middle term is -2t
f(t) = 4(t2 - 2t + 1) + 8 - 4 -2t/2 = -1; -1^2 = 1
f(t) = 4(t-1)^2 + 4 Add 1 and subtract 4 since 4*1 = 4.
The vertex (1,4) means at a minimum the roller coaster is 4 meters from the ground.
- f(t) = 4(t − 1)2 + 2; the minimum height of the roller coaster is 2 meters from the ground
- f(t) = 4(t − 1)2 + 2; the minimum height of the roller coaster is 4 meters from the ground
- f(t) = 4(t − 1)2 + 4; the minimum height of the roller coaster is 1 meter from the ground
- f(t) = 4(t − 1)2 + 4; the minimum height of the roller coaster is 4 meters from the ground
