What times what equals 225?

Answers

Answer 1

Answer:

The required factor that equals 225 is 3 × 3 × 5 × 5.

To find what times what equals 225, we can factorize 225 by finding its prime factors. Here's the step-by-step solution:

Step 1: Start by dividing 225 by the smallest prime number, 2. However, 2 does not divide 225 evenly.

Step 2: Move on to the next prime number, 3. Divide 225 by 3: 225 ÷ 3 = 75. Since 3 is a factor, we can write 225 as 3 × 75.

Step 3: Repeat the process for the quotient, which is 75. Divide 75 by 3: 75 ÷ 3 = 25. Now we have 225 = 3 × 3 × 25.

Step 4: Continue factoring the remaining quotient, 25. Divide 25 by 5: 25 ÷ 5 = 5. Now we have 225 = 3 × 3 × 5 × 5.

Step 5: Since we have reached a prime factor, which is 5, and there are no more factors to consider, we can stop factoring.

Therefore, what times what equals 225 is 3 × 3 × 5 × 5.

What is the area of the kitchen floor in this floor plan?A-24 sq meters
B-28 sq meters
C-35 sq meters
D-42 sq meters

Answers

Answer: The correct option is (C) 35 sq. meters.

Step-by-step explanation: We are given to find the area of the kitchen floor in the floor plan shown in the figure.

From the figure, we see that

the kitchen is in the form of a rectangle with length 7 meters and breadth 5 meters.

We know that

the area of a rectangle with length l units and breadth b units is given by

$A=l* b.$

For the rectangular kitchen, we have

length, l = 7 meters

and

breadth, b = 5 meters.

Therefore, the area of the kitchen floor in the floor plan is given by

$A=l* b=7* 5=35~\textup{sq. meters}.$

Thus, option (C) is CORRECT.

First you would figure out the dimensions, which are 7 ft by 5 ft. Then, multiply those together, which equals 35 sq ft. The answer to your question is C - 35 sq ft. Hope this helps!

Geoff planted dahlias in his garden. Dahlias have bulbs that divide and reproduce underground. In the first year, Geoff’s garden produced 8 bulbs. In the second year, it produced 16 bulbs, and in the third year it produced 32 bulbs. If this pattern continues, how many bulbs should Geoff expect in the sixth year?A. 64
B. 512
C. 128
D. 256

Answers

1st = 8, 2nd = 16, 3rd = 32, doubling each time so 4th = 64, 5th = 128,

6th = 256

Solve for x. -ax+4b>9

Answers

-ax+4b>9
-ax>9-4b
-x>(9-4b)/a
x<-(9-4b)/a
x<(4b-9)/a

Answer: x<-(9-4b)/a or x<(4b-9)/a

Let's solve for a.(−a)(x)+4b>9Step 1: Add -4b to both sides. −ax+4b+−4b>9+−4b −ax>−4b+9
Step 2: Divide both sides by -x. −ax−x>−4b+9−x a<4b−9x

Log x + log 8 = 2 ???

Answers

To start we will use the sum to product rule of logs to make logx + log 8 = 2 -> log8x = 2. now assuming that this is log base 10 we will get rid of the log by raising both sides to the power of ten.

8x = 10^2
8x = 100
x = 100/8

The solution to the equation $log(x) + log(8) = 2$ is $x = 12.5$ .
