Answer:
x = 5
Step-by-step explanation:
Since the triangles are similar, corrresponding sides are in proportion.
[tex]\frac{NM}{SR} = \frac{ML}{RL} = \frac{NL}{SL}[/tex]
Using the equation formed by the second and third fraction above we get
[tex]\frac{28}{24} = \frac{3x - 1}{x + 7}[/tex]
28(x + 7) = 24(3x - 1)
28x + 196 = 72x - 24
44x = 220
x = 5

Answer:
30
Step-by-step explanation:
Answer:
1.) B.) 30
2.) D.) 2.38
Step-by-step explanation:
1.) The answer is B because when the encyclopedia first went live there were 30 articles in it.
2.) The answer is D because the product first started out as $38⁰⁰ and each year it is decreasing half the amount of the year before it and it does this for 4 years:
Start: Year 1: Year 2: Year 3: Year 4:
$38⁰⁰ ÷ 2 = $19 ÷ 2 = $9⁵⁰ ÷ 2 = $4⁷⁵ ÷ 2 = $2³⁸ <--- I rounded up because 2.375 is closer to 2.38

Calculate 48 x 3/8 choose the numbers to complete the equation
Answer:
1. Choose: 3
2. Choose: 144
3. Choose: 18
Step-by-step explanation:
The first thing you do is multiply 48 * 3/8= 18. Then multiply 48 * 1/8= 6. Then divide both answers to get 3, so 48 * 1/8 * 3.
Then to find the second Choose option, you know that 48 * 1/8 * 3= 18; so 18 * 8= 144(to check your answer, divide 144/8 = 18).
Finally, to find the third Choose option, you divide the fraction 144/8 = 18.

A Mars rover descended from the rim of a crater at a constant rate. After 2 days, the rover's elevation was 106 meters. After 6 days, its elevation was 48 meters. What elevation did the rover start at? ____meters Complete the equation that describes the relationship between the rover's elevation in meters, E, and the elapsed time in days, t. Write your answer using whole numbers or decimals rounded to the nearest tenth. E= ___ t+____
Answer:
135
E = - 14.5t + 135
Step-by-step explanation:
Given that, descent rate is constant ;
Elevation after 2 days = 106 m
Elevation after 6 days = 48 m
Let
Rate of elevation per day= x
Initial elevation = a
Hence,
a - 2x = 106 - - - (1)
a - 6x = 48 ___(2)
-2x + 6x = 106 - 48
4x = 58
x = 58/4
x = 14.5 meters per day
Hence, initial elevation :
a - 2(14.5) = 106
a - 29 = 106
a = 106 + 29
a = 135
Relationship between Rover's elevation, E and elapsed time, t
E = - 14.5t + 135
-14.5 = rate per day

During a film festival, the first film ticket is priced at $16, and each additional ticket is $11. If Rico spends $71, then how many tickets did he purchase?
Answer:
5
Step-by-step explanation:
16 + 11x = 71
16 + -16 + 11x = 71 + -16
16 + -16 = 0
0 + 11x = 71 + -16
11x = 71 + -16
11x = 55
x = 5
What’s the inverse of this function?

The ocean's surface is at 0. Which is farthest from the ocean’s surface?
A.
a fish swimming at -22 feet
B.
a kite flying at 48 feet
C.
a shipwreck at -52 feet
D.
a balloon at 19 feet
Answer:
C. a shipwreck at -52 feet
Step-by-step explanation:
It is asking which is farthest from the ocean's surface, so we must use absolute value.
[tex] | - 22| = 22 \\ |48 | = 48 \\ | - 52| = 52\\ |19| = 19[/tex]
52 is greater than the others. therefore the farthest away.
How do I divide -x^3 + 2x^2 + 5x -4 by x+2 using synthetic division?
Answer:
-x²+4x-3+2/(x+2)
or
-x²+4x-3 remainder 2
Step-by-step explanation:
If a/b=b/c,then what is b²?
Given:
The equation is
[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]
To find:
The value of [tex]b^2[/tex].
Solution:
We have,
[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]
On cross multiplication, we get
[tex]a\times c=b\times b[/tex]
[tex]ac=b^2[/tex]
[tex]b^2=ac[/tex]
Therefore, the value of [tex]b^2[/tex] is [tex]ac[/tex].
Which equation has the greatest rate of change?
y=12x-7
y=5x+9
y=4x+12
y=X+36
Answer:
y=12x-7
Step-by-step explanation:
Rate of change is the same thing as slope which can be found by looking at the value before the x. Since 12 is the largest number, it has the largest rate of change.
