Which answer choice correctly identifies the missing information in the problem? Joey and Kirk are in the 6th grade. Kirk is 5 f

user100 [1]

Answer:Kirk is taller than Joey by 8 inches

Step-by-step explanation:

Step 1

Kirk's height is given as =5 feet 4 inches tall.

Joey's height 4 feet 8 inches tall

Difference in height = 5 feet 4 inches

- 4 feet 8 inches

Step 2

Bear in mind that 12 inches = 1 feet . Now,8 cannot be subtracted from 4 , so we borrow 1 feet from 5feet, which is equivalent to 12 inches and add to inches so it becomes

4 feet (12+4)inches = 4 feet 16inches

- 4 feet 8 inches - 4 feet 8 inches

= 8 inches

Therefore Kirk is taller than Joey by 8 inches

The formula s = StartRoot StartFraction S A Over 6 EndFraction EndRoot gives the length of the side, s, of a cube with a surface

never [62]

Answer:

$2\sqrt{2}\ ft\ longer$

Step-by-step explanation:

Area Of A Cube

Suppose a cube with side length s, the area of one side is

$A_s=s^2$

Since the cube has 6 sides, the total area is

$A=6A_s=6s^2$

But if we have the area, we can solve the above formula for s to get

$A=6s^2$

$\displaystyle s=\sqrt{\frac{A}{6}}$

We have two different cubes with areas 1,200 square inches and 768 square inches. Let's compute their side lengths

$\displaystyle s_1=\sqrt{\frac{1,200}{6}}=\sqrt{200}$

$\displaystyle s_1=10\sqrt{2}\ ft$

$\displaystyle s_2=\sqrt{\frac{768}{6}}=\sqrt{128}$

$\displaystyle s_2=8\sqrt{2} ft$

The difference between them is

$10\sqrt{2}\ ft-8\sqrt{2}\ ft=2\sqrt{2}\ ft\approx 2.83\ ft$

The side of the cube with area 1,200 square inches is $2\sqrt{2}\ ft$ longer then the side of the cube with area 768 square inches

Find each measurement to the nearest tenth use 3.14 for pi. r=_ ; d=_ ; C= 17.8 m

jarptica [38.1K]

C = pi×diameter OR C = 2pi×radius
So...
17.8 = pi×diameter 17.8 = 2pi×radius
17.8/pi = diameter 17.8/2pi = radius
5.66591597407 = diameter or d
2.83295798704 = radius or r

Choose the graph which matches the function. (2 points) f(x) = 3x-4

vovangra [49]

The last image is the graph of $y = 3^x$

In fact, it is an increasing exponential function, and it passes through the points $(0,1)$ , which reflects the fact that $3^0=1$ and $(1,3)$ , which reflects the fact that $3^1=3$ .

Now, $y = 3^{x-4}$ is a child of the parent function we just described. Precisely, it is the result of the transformation $f(x) \to f(x-4)$

In general, every time you perform a transformation like $f(x) \to f(x+k)$ , you translate the graph horizontall, k units to the left if k is positive, and k units to the right if k in negative.

Since in this case $k = - 4$ , we have a horizontal translation of 4 units to the right.

So, the correct option is the third one, because:

The first graph is the parent function translated 4 units to the left
The second graph is the parent function translated 4 units down
The third graph is the parent function translated 4 units to the right
The fourth graph is the parent function
