FORMULA:

TSA of cubes = 6(a)²

ANSWER:

We just have to plug the respective value.

So, TSA of 8 cubes = 6 × (12)²

6 × 144
864ft².

So, <u>Correct choice</u> - [C] 864 ft².

Eloise scored a total of 268 points during the basketball season. Of her total points, l points came from left handed shots. She

Naddik [55]

Answer:

$\bold{268=225+}l$

Step-by-step explanation:

Given that:

Total points scored in basketball season, T = 268

Points scored from right handed shots, R = 225

Points scored from left handed shots = $l$

To find:

To write an equation to describe the situation and find the value of $l$ for left handed shots ?

Solution:

We know that the points can be scored in basketball either by right hand shots or by left hand shots.

In other words, we can say that:

Total points scored in basketball season = points scored from right handed shots + points scored from left handed shots

i.e.

$T = R + l\\\Rightarrow \bold{268=225+}l$

So, the equation is:

$\bold{268=225+}l$

Now, let us find the value of $l$ from the above equation:

$l=268-225\\\Rightarrow \bold{l = 43}$

Number of points scored from left handed shots = <em>43</em>

The ratio is 8:9 is the ratio between 0.45 - 0.60?

bagirrra123 [75]

Divide 8 by 9

8 / 9 = 0.888

0.88 is greater than 0.60 so it is not between 0.45 - 0.60

The ratio of the areas of the two squares is 25 to 9. The side length of the smaller square is 30 meters. How long is the side l

Ratling [72]

Ratios of Area of the two squares = 25:9
So then let the areas be A1 = 25A and A2 = 9A, A is common element
Side of the smaller area S2 = 30 meters
Area of the smaller square A2 = 30 x 30 = 900
We have area of smaller square as 9A = 900 => A = 100
Area of the large square = 25A = 25 x 100 = 2500.
Hence S1^2 = 2500 => S1 = 50 meters which is 20 meters longer than the
side of the smaller square.

Solve 4 over x minus 4 equals the quantity of x over x minus 4, minus four thirds for x and determine if the solution is extrane

Vinil7 [7]

I'm thinking this is what the problem looks like: $\frac{4}{x-4}= \frac{x}{x-4}- \frac{4}{3}$ . The first thing to do is to move the $\frac{x}{x-4}$ over to the other side because it has a common denominator with the other side. Doing that and at the same time combining them over their common denominator looks like this: $\frac{4-x}{x-4}= -\frac{4}{3}$ . The best way to solve for x now is to cross-multiply to get 3(4-x)=-4(x-4). Distributing through the parenthesis is 12 - 3x = -4x + 16. Solving for x gives us x = 4. Of course when we sub a 4 back in for x we get real problems, don't we? Dividing by zero breaks every rule in math that there ever was! So, yes, the solution is extraneous.
