Answer: 40

Step-by-step explanation:

Given : Deandre downloaded 8 apps onto his tablet in 12 seconds.

By using UNITARY METHOD, the number of apps he download in one seconds will be :-

$\dfrac{8}{12}=\dfrac{2}{3}$

Also, 1 minute = 60 seconds

At this rate, the number of apps he can download in 60 seconds will be :-

$\dfrac{2}{3}\times60=40$

Hence, the number of apps he can download in one minute = 40

Answer:

40 apps

Step-by-step explanation:

8 apps per 12 seconds is a rate of 8/12 (apps/sec) = 2/3 (apps/sec)

2/3 (apps/sec) × 60 (sec) = 40 (apps)

d1i1m1o1n [39]

Solution :

The minimum distance from Earth to the Sun is 91.4 million miles

The maximum distance is 94.5 million miles

$d_{min} = 91.4, d_{max} = 94.5$

$d=\frac{d_{min} + d_{max}}{2}$

$d=\frac{91.4 + 94.5}{2}$

d=92.95

$d_{sol}=\frac{d_{max} - d_{min}}{2}$

$d_{sol}=\frac{94.5 - 91.4}{2}$

$d_{sol} =1.55$

Absolute Value Equation:

|x - d| = $d_{sol}$

|x - 92.95| = 1.55

Joanie is organizing her closet. She has 3 times as many black shirts as gray shirts, plus 3 new black shirts she just bought. S

marin [14]

Answer:

Option A. 2

Step-by-step explanation:

To solve this problem we can write equations for each shirt color.

Let's call:

b = black shirts

g = gray shirts

w = white shirts

B = brown shirts

If you have 3 times more black shirts than gray shirts and buy 3 more black shirts then:

$b = 3g +3$ (i)

If you have 5 times more white shirts than gray shirts and gave a white shirt then:

$w = 5g -1$ (ii)

It has 2 times more gray shirts than brown camsas, then:

$g = 2B$ (iii)

It has the same amount of black and white shirts

$b = w$ (iv)

We want to find the number of gray shirts.

Then replace (iv) in (ii)

$b = 5g -1$ (v)

Now substitute (v) into (i) and clear g.

$5g -1 = 3g +3\\\\5g -3g = 3 +1\\\\2g = 4\\\\g = 2$

Joan has 2 gray shirts

5 Show different ways to make 492,623.

timama [110]

Step-by-step explanation:

Start by writing 492,623 in standard form

4 hundred thousands + 9 ten thousands + 2 thousands + 6 hundreds + 2 tens + 3 ones

We can write this in other ways by moving a digit to the next smaller place value. For example, we move the 4 one place to the right to get 49 ten thousands:

49 ten thousands + 2 thousands + 6 hundreds + 2 tens + 3 ones

Then, we can move the 49 ten thousands to the right to get 492 thousands, and we can move 6 hundreds to the right to get 62 tens.

492 thousands + 62 tens + 3 ones

Or, we can do this:

4926 hundreds + 23 ones
