When Sarah divided a number by 5, the quotient was 247 with a remainder. What is one possible dividend? With a complete sentence

Stolb23 [73]

Answer:

When a number is divided by 5 and the result is 247 with a remainder, one possible dividend is 1236.

The quotient of a number is the number that is gotten when a number is divided by another number. For example, the quotient of 10 and 2 is 5.

An unknown number was divided by 5 and the result was 247 with a remainder. In order to determine the number the first step is to determine the product of 247 and 5.

247 x 5 = 1235

Since the number has a remainder, the number cannot be exactly 1235. The number would lie between 1235 and 1240. The numbers can be 1236, 1237, 1238 and 1239.

7. Eduardo has $150 in savings and makes $9.75 per hour. Jennifer has $90 in savings and earns $15.25 for each

Stells [14]

Answer:

a) 150-90 = h(15.25 -9.75)

b) 10.91

Step-by-step explanation:

a) Jennifer has 150 -90 = 60 less in savings than Eduardo, but she is earning 15.25 -9.75 = 5.50 more per hour. An equation she can use to figure her hours is ...

60 = 5.50h . . . . for h hours worked.

In 'raw' form, that might be ...

150 -90 = (15.25 -9.75)h

b) Solving the above equation, we get ...

60/5.50 = h ≈ 10.90909 ≈ 10.91 . . . hours

$\pi r {}^{2} h$

where,

r = radius
h = height

now, let's solve

=》

$3.14 \times 7 \times 7 \times 13$

=》

$2000.18$

So, volume = 2000.2 cm³

The average temperature of coffee in the sample, which is 70.2.

Step-by-step explanation:

The population is all the costumers. The company has determined that they want the average coffee temperature to be 65 degrees C. So, 65 degrees C is the average of the population.

The sample is the 20 orders. The mean $\mu$ of the sample is 70.2C(That is, the mean of the 20 orders0. So, the correct answer is:

The average temperature of coffee in the sample, which is 70.2.
