Answer:
D. 4/7 = 24/28
Step-by-step explanation:
In any proportion, the value of the numerator and denominator does not change if is multiplied by the same value.
We know that 4*6 = 24, so the numerator holds true. However, 7*6 is 42. In the same vein, 7*4 is 28, so the denominator would hold true. However, 4*4 is 16. Thus, the proportion has not been multiplied by the same value.
In order to get 24/28 from 4/7, you would have to multiply by 6/4, which is not the same value.
Answer:
length=11 width=10
Step-by-step explanation:
Create two equations with length(l) and breath(w) as our unknowns
2l+2w=42
2l=42-2w
2l/2=(42-2w)/2
l=21-w(equation 1)
lxw=110
lw=110
Substitute equation one into equation two
(21-w)w=110
21w-w²=110
Write your equations in standard quadratic form
0=w²-21w+110
solve this as a quadriatic tri nominal
0=(w-10)(w-11)
0=w-10. or 0=w-11
10=W. 11=L
7) Larger number= 30
Smaller number= 18
8) He bought 4 videogames and 11 movies.
When the dilation is around the origin, we just have to multiply each coordinate by the scale factor.
We're starting from A(2,2), B(2,5), C(6,5) and D(6,2) and scaling by 3 so the image A'B'C'D' is
Answer: A'(6,6), B'(6,15), C'(18,15), D'(18,6)
Answer:
6 questions
Step-by-step explanation:
<u>First</u>, you divide the total score of 100 by the 64 questions to get 1.5625 points per question. <u>Next</u>, you divide the lowest score to qualify of 90 by the 1.5625 to get 57.6 questions correct to qualify. <u>Then</u>, you round 57.6 questions correct up to 58 questions correct because a fraction of a question correct doesn't make sense. <u>Finally</u>, you subtract the total number of questions (64) by the required correct answers (58) to get 6 questions you can miss to still qualify for the scholarship.
