Select all that apply.Which of the following expressions could you use to estimate 47% of 89?


1/2 · 90
0.5 · 90
0.47 · 89
90/2

Answers

Given: 
47% of 89

Exact solution is : 0.47 * 89 = 41.83

Estimates: you round the number to the nearest tens.
47% can be 50% ; 89 can be 90

0.50 * 90 = 45

50% is the same as 1/2
1/2 * 90 = 45

90/2 is also applicable to estimate for the above figure. 90/2 = 45

Which of the following represents "next integer after the integer n"?On
On + 1
O2n

Answers

Answer:

Option B.

Step-by-step explanation:

Integer: A non fractional complete number is known as integer. It can be either positive or negative or zero.

For examples : ...,-3,-2,-1,0,1,2,3,...

It is a clear that the difference between two consecutive integers is 1. It means we have to add 1 in the integer to get the next integer.

We need to express "next integer after the integer n" mathematically. So, we need to add 1 in n.

Required expression =n+1

Hence, the next integer after the integer n is n+1.

Therefore, the correct option is B.

jill is making a long cape she needs 4 1/3 yards of blue fabric for the outside of the cape she needs 3 2/3 yards of purple fabric for the lining of the cape

Answers

Answer:

Jill needs 8 yards of fabric to make a cape.

Step-by-step explanation:

Givens

  • Jill needs 4 1/3 yards of blue fabric for the outside of teh cape.
  • Also she needs 3 2/3 yards of purple fabric for the lining.

In order to know the total number of yards Jill needs to make a cape, we first need to transform each mixed number into fraction. We do that multiplying the whole part with the denominator and then adding it to the numerator, as follows

4(1)/(3)=(13)/(3) \n3(2)/(3)=(11)/(3)

Then, we sum both fractions

(13)/(3) +(11)/(3)=(13+11)/(3)=(24)/(3) =8

Therefore, Jill needs 8 yards of fabric to make a cape.
Hey there, just subtract 4 1/3 from 3 2/3 to get your answer. 4 1/3=13/3 and 3 2/3=11/3, 13*3-11*3/3*3=39-33/9=6/9, 6/9 simplified is 2/3

Manny makes dinner using 1 box of pasta and 1 jar of sauce. if pasta is sold in packages of 6 boxes and sauce is sold in packages of 3 jars, what is the least number of dinners that Manny can make without any supplies leftover?

Answers

You need to find the least common multiple of 6 and 3. This the minimum whole number that contains the number of boxes in one package of pasta and the number of jars in one package of sauce. t he least common multiple of 6 and 3 is 6. This means that Manny can make 6 dinners, which will be made with 1 package of pasta (6 boxes ) and two packages of sauce (2 * 3 = 6 jars).
