How do you know that 4x2x2 is the same as 4x4

Answers

Answer 1

Answer: If you would like to know if 4x2x2 is the same as 4x4, you can find out using the following step:

2x2 equals to 4, so instead of 2x2 you can write 4.

The result is: 4x2x2 = 4x(2x2) = 4x4, which is the same as 4x4 in the second part of the question.

Answer 2

Answer: Because 2×2=4
so 4×4=16
and 4×2×2=16

99% is my guess because there are 2 white golf balls and the rest are yellow. i am just thinking logically.

If the smallest angle of a triangle is 20 degrees and it is included between sides of 4 and 7, then (to the nearest tenth) the smallest side of the triangle is 3.2 - true or false?

Answers

Answer:

The answer is False

Step-by-step explanation:

we know that

Applying the law of cosines, find the length of the third side of the triangle

$c^(2)= a^(2)+b^(2)-2abcos(C)$

In this problem we have

$a=4\ units, b=7\ units, C=20\°$

substitute the values and solve for c

$c^(2)= 4^(2)+7^(2)-2*(4*7)*cos(20\°)$

$c= 3.5\ units$ -------> smallest side of the triangle

therefore

$3.5\neq 3.2$

Hello,
Al 'Kashi theorem says:

a²=4²+7²-2*4*7*cos 20°=12.37721...
==>a=3.518126381...≈3.5 ==>False.

in example 4A,simon raised a total of $25.00 for selling 10 candles.if simon raised $30.00 for selling 10 candles ,would the unit rate be higher or lower explain.

Answers

The unit rate would be higher if Simon raised $30.00 for selling 10 candles.

What is rate ?

In math, a rate is a ratio that compares two different quantities which have different units.

Now given that,

Total candle sold = 10

Total amount of 10 candles = $25.00

Thus, amount per candle = $25/10

⇒ amount per candle = $2.5

Similarly, Total candle sold = 10

Total amount of 10 candles = $30.00

Thus, amount per candle = $30/10

⇒ amount per candle = $3

Now, since total of $30.00 for selling 10 candles is greater than total of $25.00 for selling 10 candles.

Thus, the unit rate would be higher.

Thus, the unit rate would be higher if Simon raised $30.00 for selling 10 candles.

higher: 25.00÷10=$2.50 and 30.00÷10=$3.00

so the unit rate is higher

Justin weighs 15 pounds less than Greg weighs. Half of Greg’s weight is 75 pounds less than Justin’s weight. How much does each of them weigh

Answers

The answer is:
Justin weighs 165 pounds.
Greg weighs 180 pounds.

If:
j - Justin's weight
g - Greg's weight

Then the system of equations is:
j + 15 = g ⇒ g = j + 15
1/2g = j - 75 ⇒ j = 1/2g + 75

We can replace j in the first equation:
g = 1/2g + 75 + 15
g - 1/2g = 90
1/2g = 90
⇒ g = 90 ÷ 1/2 = 180

Thus, Greg weighs 180 pounds.

Now, using the first equation, we will calculate Justin's weight:
j + 15 = g ⇒ j = g - 15
g = 180

Thus
j = g - 15 = 180 - 15 = 165

Therefore, Justin weighs 165 pounds.
