Answer:
91
Step-by-step explanation:
Todd’s average score for six tests = 92.
The sum of two of her test = 188
First, we need to find the total score for the six test. This given below:
Average = sum of all test / number of test
sum of all the test = average x number of test
average score for six tests = 92.
Number of test = 6
Sum of all the Tests = 92 x 6 = 552
Sum of four test = sum of all the test — sum of two test
Sum of four test = 552 — 188 = 364
Now we can solve for the average of the other four test as shown below:
Average of four test = 364/4= 91
Answer:
depends on the sized of the room-send picture so I can help
Step-by-step explanation:
The scale factor of the similar triangles is: 1/2. The value of x is: 4.5 cm.
<h3>Scale Factor of Similar Triangles</h3>
Scale factor of similar triangles is the ratio of their corresponding sides.
Given the two similar triangles in the diagram attached below, we have the following scale factor as:
Scale factor = 2/4 = 1/2
Therefore:
x = 1/2 × 9
x = 4.5 cm.
Therefore, the scale factor of the similar triangles is: 1/2. The value of x is: 4.5 cm.

Answer: 7.29 or 7 1/4 or 29/4 (they're all equal, just rewritten)
Step-by-step explanation:
the angles are equal, so we set the equations to each other and then solve. here's my work:
12k - 9 = 8k + 20
12k (- 8k) - 9 = 8k ( - 8k) + 20
4k - 9 = 20
4k -9 ( + 9) = 20 ( + 9)
4k = 29
k = 7.29 or 7 1/4 or 29/4
Answer:
The fourth option
Step-by-step explanation:
48 is the minimum height, 42 is his current height, and h is the height he must grow. 42 +h is at least 48 so that rules out the first and third options. The second option would be around twice the required height, so it must be the fourth option.
