Scale Factor
What scale factor was applied to the first rectangle to get the
resulting image?
Enter your answer as a decimal in the box.
Answer:
Scale factor = 2.5
Step-by-step explanation:
The scale factor that was applied = length of the resulting image ÷ length of the first rectangle
Length of resulting image = 7.5
Length for first rectangle = 3
Scale factor = 7.5/3 = 2.5

Gabrielle is 13 years older than Mikhail. the sum of their ages is 113. what is mikhails age?
Step-by-step explanation:
g=m+13
g+m=113
use substitution
Answer:
50 years old
Step-by-step explanation:
Let's say that Mikhail's age is x.
If so, Gabrielle's age would be 13 years older, therefore x + 13
We know that the sum of their ages is 113, so we can form this equation:
x + x + 13 = 113
Solving this equation, we get:
x + x = 100
2x = 100
x = 50
50 is Mikhail's age, so Gabrielle's age is 63

Need help please confused
Answer:
a. 11.6 (rounded to nearest tenth)
b. Yes
Step-by-step explanation:
a²+b² = c²
6²+10² = c²
36²+100 = c²
136 = c²
√136 = √c²
11.6 = c
b. because 11.6 is the hypotenuse (longest side length) and there is 6 and 10 as the shorter leg lengths.

Step-by-step explanation:
tanx cscx= 1/f(x)
simplify and write the trigonometric expression in terms of sine and cosine
Answer:
f(x) = cos(x)
Step-by-step explanation:
tanx cscx = (sinx/cosx) * (1/sinx) = 1/cosx
1/f(x) = 1/cosx
f(x) = cos(x)
The given trigonometric equation in terms of sine and cosine is f(x)=cosx.
The given trigonometric function is tanx·cscx= 1/f(x).
What is the trigonometric equation?A trigonometric equation is one that involves one or more of the sixs sine, cosine, tangent, cotangent, secant, and cosecant. Some trigonometric equations, like x = cos x, can be solved only numerically, through successive approximations.
We know that, tanx = sinx/cosx and cscx=1/sinx
Now, 1/f(x) = tanx·cscx
= sinx/cosx × 1/sinx
= 1/cosx
So, 1/f(x) = 1/cosx
Take inverse on both the side of equation, we get
f(x)=cosx
Hence, the given trigonometric equation in terms of sine and cosine is f(x)=cosx.

THE amusement park won't allow kids to ride roller-coasters until they are a minimum of 48 inches tall. Michael is now 42 inches tall, and grows about 1/2 inch every month. How many months will it be until Michael can read a roller coaster? Please show me the individual steps?
Answer: It will one year (or 12 months) before Michael is able to ride the roller coaster.
Step-by-step explanation: Because he grows a half inch every month, this means that It takes him two months to grow one full inch. Because he has to grow six inches, you just multiply 2 by 6 to get 12 months or one year.
Answer:
48-42=6, which is how much Michael needs to grow.
1/2x=6, where x is the number of months
x = 12 months.
1 year = 12 months so the answer is one year.
Solve this equation for a: 6a + 3 = 45
A.6
B.7
C.8
D.9
Answer: 7
Step-by-step explanation:
6 x 7 = 42
42+3 =45
Therefore 7 is the answer
Answer:
B. 7
Step-by-step explanation:
Answer to A. 6 = 6(6) + 3 = 39 (wrong answer)
Answer to B. 7 = 6(7) + 3 = 45 (correct answer)
Answer to C. 8 = 6(8) + 3 = 51 (wrong answer)
Answer to D. 9 = 6(9) + 3 = 57 (wrong answer)

Out of 4,000 colleges surveyed, 60% reported that SAT scores were not used as a high consideration in viewing their applications. How many schools view the SAT as important in screening applicants?
Answer:
Hi.
The first thing you want to know is how many schools 60% is.
To find 60%: 4,000 x 0.6 (b/c 0.6 = 60%)
so, 60% of 4,000 = 2,400
To find the number of schools that consider SAT scores:
Subtract 2,400 from 4,000 which, equals 1,600
or
Find the remaining percentage; 40%:
4,000 x 0.4 = 1,600
Answer: 1,600 colleges
