Answer:

Students will begin to lay the foundation for fractions in second grade. Students have experienced fractions in first grade through geometric shapes. Students should understand that the inverse relationship between the size of the fractional part and the number of equal parts in the whole when given the same size whole. The greater the number of parts, the smaller the size of the parts and the smaller the number of parts, the greater the size of the parts.

Second grade students do not use or write in fraction notation (a/b) as they use written words to describe the relationship of fractions. Students should also have a great understanding that each fractional part of an object is the same size in area and the same shape and that the orientation of the partitioned parts does not affect the size in area or shape of the parts.

A company is considering a new manufacturing process. It knows that the rate of savings (in dollars per year) from the process w

Ainat [17]

Answer:

i). $\$ 7500$

ii). $\$ 67500$

Step-by-step explanation:

Given in the question-

Saving rate is s(t)= 3000(t+2)

We know that savings in the 1st year can be calculated as

$\int_{0}^{1}3000(t+2).dt$

$3000\left [ \frac{t^{2}}{2}+2t \right ]_0^1$

$3000\left [ \frac{1}{2}+2 \right ]$

= $\$ 7500$

So savings in the first 5 years can be calculated as

$\int_{0}^{5}3000(t+2).dt$

$3000\left [ \frac{t^{2}}{2}+2t \right ]_0^5$

$3000\left [ \frac{25}{2}+5 \right ]$

= $\$ 67500$

In a candy store , a $12.00 jar of candy is labeled , " 35% off ." What is the discount ? What is the sale price of the jar of c

MA_775_DIABLO [31]

Answer:

$7.80

Step-by-step explanation:

Tjar originally costs $12.00. It is marked 35% off. This means of the original price, you pay 65% of it since 100%-35%=65%.

To find the sale price, multiply the original price by 65%. In order to do that you must convert the percent to a decimal first.

65% becomes 0.65

We multiply 12(0.65)=7.8.

The sale price is $7.80
