Answer:

67%

Step-by-step explanation:

There are a few methods to finding the percent of a number. You can use proportions:

$\frac{percent}{100}=\frac{48}{72}$

The 'percent' is the percent of the fraction that you are looking for, or 48/72.

Cross-multiply: 72x = (48)(100) or 72x = 4800

Divide both sides by 72: 72x/72 = 4800/72

Solve for 'x': x = 66.6666...

Round 66.666.... to the nearest percent: 67%

A large bag or sugar weighs 7 1/2 lb. Gow Much does 1 1/4 bags of sugar weighs

arsen [322]

Answer:

The correct option is 4.

Step-by-step explanation:

It is given that the weight of a large bag of sugar is $7\frac{1}{2}$ . This complex fraction can be written as

$7\frac{1}{2}=\frac{14+1}{2}=\frac{15}{2}$

So, the weight of a large bag of sugar is $\frac{15}{2}$ .

The number of bags is $1\frac{1}{4}$ . It means the number of bags is number of bags is $\frac{5}{4}$ .

$1\text{ Bag}=\frac{15}{2}\text{ lb}$

Multiply both side by $\frac{5}{4}$ .

$1\times \frac{5}{4}\text{ Bag}=\frac{15}{2}\times \frac{5}{4}\text{ lb}$

$\frac{5}{4}\text{ Bag}=\frac{75}{8}\text{ lb}$

$\frac{5}{4}\text{ Bag}=9\frac{3}{8}\text{ lb}$

Therefore correct option is 4.

Clara is growing her hair out and wants it to be no longer than 15 cm but more than 11 cm. Her hair is 7 cm right now and grows

sertanlavr [38]

For this case we have the following compound inequality:
11 <7 + 0.25t ≤ 15
We must solve this inequality for time.
We have then:

For 11 <7 + 0.25t:
11 <7 + 0.25t
11 - 7 <0.25t
4 <0.25t
4 / 0.25 <t
16 <t

For 7 + 0.25t ≤ 15:
7 + 0.25t ≤ 15
0.25t ≤ 15 - 7
0.25t ≤ 8
t ≤ 8 / 0.25
t ≤ 32

Therefore, the answer is:
16 <t ≤ 32

Answer:
16 <t ≤ 32
Clara has the desired length in more than 16 weeks, but up to 32 weeks.

Somebody please help me with this

Answer:

15/56

Step-by-step explanation:

5 people have a license

3 people don't

? = Probability that first person has a license and second does not

We can divide the problem into two sections, the first being the probability of the first person having a license, and the second section is the probability that the second person doesn't have a license.

P1 = Probability of the first person having a license, there are 5 out of 8 person having a license, thus P1 = 5/8.

P2 = Probability of the second person having a license. There are 3 people not having a license, out of 8-1 = 7 persons available, since one is taken already from the first choice, therefore P2 = 3/7.

P1 and P2 are dependent events, thus P(1,2) = P1 * P2.

P(1,2) = P1 * P1 = 5/8 * 3/7 = 15/56

Distance between (-10,9) and (-5,2)

jonny [76]

Answer:

8.60 units (3 s.f.)

Step-by-step explanation:

The distance between 2 points is given by the formula:

$\sqrt{(y1 - y2)^{2} + {(x1 - x2)}^{2} }$

Thus using the above formula,

Distance between (-10, 9) and (-5, 2)

$= \sqrt{ {(9 - 2)}^{2} + {( - 10 + 5)}^{2} } \\ = \sqrt{ {7}^{2} + ( - 5)^{2} } \\ = \sqrt{74} \\ = 8.60 \: units \: (3 \: s.f.)$

A cake decorator rolls a piece of stiff paper to form a cone. She cuts off the tip of the cone and uses it as a funnel to pour d

Nimfa-mama [501]

Answer:

Step-by-step explanation:

Use the formula for volume of a cone

V = 1/3 pi r^2 (h)

V = 1/3 pi 66^2 (18)

V= 1/3 pi 4356(18)

V = 1/3 pi 78408

V = 1/3 264,201.12

V = 82,067.04cm^3
