I think you would multiply 20 × 4 and the answer would be 80 that the scientist counted the number of plants in each 4 sections after 20 days.

The graph represents the speed at which Pete’s marble travels.

AfilCa [17]

Answer:

B

Step-by-step explanation:

Here, we simply want to know who will reach the 6-foot mark sooner

Mathematically, we need to get the slope from the graph

Looking at the graph, we can see that the 3 ft mark was reached at exactly 2 seconds

So what this mean is that, in 4 seconds, the 6 ft mark will be reached

This makes up the fact that the speed for Pete’s travel is 1.5 ft/ secs

Now compare this with what Stephano has, which is 2.25 ft/ s

we can see that stephano is traveling at a better speed and will reach the 6 ft mark first

So the correct option is B

Which step shows the result of applying the subtraction property of equality? One-fourth (12 x + 8) + 4 = 3 Step Solution 1 3 x

luda_lava [24]

Answer:

Step-by-step explanation:

Given the equation 1/4 (12 x + 8) + 4 = 3, to fnd the result of the equation, the following steps must be followed.

Step 1: Expand the bracket at the left hand side of the equation using the distributive property.

1/4 (12 x + 8) + 4 = 3

$\frac{1}{4} (12x)+\frac{1}{4}(8) + 4 = 3\\ 3x+2+4 = 3\\3x+6=3$

Step 2: Subtract 6 from both sides of the equation

$3x+6-6 = 3-6\\3x =-3\\x = \frac{-3}{3}\\ x = -1$

762,508 expanded form using exponents

r-ruslan [8.4K]

762,508 in expanded form using exponents is given as:

$7 \times 10^5 + 6 \times 10^4 + 2 \times 10^3 + 5 \times 10^2 +0 \times 10^1 + 8 \times 10^0$

<h3><u>Solution:</u></h3>

Given that we have to write 762, 508 in expanded form using exponents

Expanded form or expanded notation is a way of writing numbers to see the math value of individual digits

<h3><u>Write 762508 in Expanded form</u></h3>

Let us first find the place value of digits

Place value can be defined as the value represented by a digit in a number on the basis of its position in the number.

Place value of 7 = 700000

In 762508, 7 is in hundred-thousands place

Place value of 6 = 60000

In 762508, 6 is in ten-thousands place.

Place value of 2 = 2000

In 762508, 2 is in thousands place

Place value of 5 = 500

In 762508, 5 is in hundreds place

Place value of 0 = 0 x 10 = 0

In 762508, 0 is in tens place

Place value of 8 = 8

In 762508, 8 is in ones place

Therefore, the expanded form is given as:

700,000 + 60,000 + 2,000 + 500 + 0 + 8

<u><em>Using exponents we can write as,</em></u>

$7 \times 10^5 + 6 \times 10^4 + 2 \times 10^3 + 5 \times 10^2 +0 \times 10^1 + 8 \times 10^0$

GREYUIT [131]

700*600=420,000
420,000/10=42,000
Diameter = 25
so radius = 12.5
Pi*12.5^2=625/4Pi
42,000/625/4 Pi =86.56169741
=86.6
she can fit 86 tins
