Explain why u would make one of the ascends a tens number when solving an addition problem

1 answer:

5 0

Children will use the Make a Ten strategy in this lesson, along with other strategies. Remind children that if they are adding two numbers such as 8 + 5, they can regroup the numbers to make adding easier. Tell children that they can take 2 from the 5 and add the 2 to 8 to make a ten. Also remind them that they must remember to subtract the 2 from the 5, leaving a 3, so they add 10 and 3 and get 13. Tell children that they will use this strategy to add two-digit numbers.

Materials: overhead projector, ten-frames and counters, tens and ones workmat, bundles of 10 craft sticks and single sticks, large number line, and large hundred chart

Preparation: Prepare a tens and ones workmat and a ten frame for use on the overhead. Make 9 bundles of craft sticks, 10 per bundle, using rubber bands to hold them together. Or use tens and ones blocks. Make a large number line and hundred chart for the classroom.

Prerequisite Skills and Concepts: Children should know the addition facts to 20 and the strategies used in learning them.

The average depth of the ocean is about

Dafna1 [17]

The height, in meters, of the tallest tower on the Incheon Bridge is 230.5 meters

From the question,

The average depth of the ocean is about 3688 meters.

Also,

To reach this depth, one would have to stack the tallest tower of the Incheon Bridge in South Korea 16 times.

Now, to determine the height, in meters, of the tallest tower on the Incheon Bridge,

We will divide the average depth of the ocean by 16

That is,

The height of the tallest tower on the Incheon Bridge = 3688 m ÷ 16

∴ The height of the tallest tower on the Incheon Bridge = 230.5 meters

Hence, the height, in meters, of the tallest tower on the Incheon Bridge is 230.5 meters

A sphere has a radius of 6 inches. What is the volume of the sphere in terms of π?

natka813 [3]

The volume of sphere in terms of $\pi$ is 288 $\pi$ cubic inches, if the sphere has a radius of 6 inches.

Step-by-step explanation:

The given is,

A sphere has a radius of 6 inches

Step:1

Formula for volume of sphere is,

$Volume, V =\frac{4}{3}\pi r^{3}$ ...........................(1)

where, r - radius of sphere

From given,

r - 6 inches

Equation (1) becomes,

$= \frac{4}{3}\pi (6)^{3}$

= $\frac{4}{3} \pi(216)$ ( ∵ $6^{3}$ = 6×6×6 =216 )

= $(1.3333)\pi (216)$

( The volume of the sphere in terms of π, So keep the value of $\pi$ )

= 288 $\pi$

= 288 $\pi$ Cubic inches

Volume of sphere, V = 288 $\pi$ Cubic inches

Result:

The volume of sphere in terms of $\pi$ is 288 $\pi$ cubic inches, if the sphere has a radius of 6 inches.

asambeis [7]

Answer:

The grade point average of the student is 49.92.

Step-by-step explanation:

A student earned grades : C, A, B, and A

Corresponding numbers of credit hours : 44, 66, 11, and 66

Assigns quality points to letter grades :

A = 4 , B = 3 , C = 2 , D = 1 , F = 0

The grade point average (GPA):

$\frac{\sum (\text{grade point}\times \text{credit hours})}{\sum (\text{grade point})}$

$=\frac{2\times 44+4\times 66+3\times 11+4\times 66}{2+4+3+4}$

$=\frac{649}{13}=49.9230\approx 49.92$

The grade point average of the student is 49.92.
