70?
Step-by-step explanation:
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
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.

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.

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

^Solve for x. Please help me if you can I really need the answer
Answer:
x ≈ 25.1
Step-by-step explanation:
Using the sine ratio in the right triangle
sin26° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{11}{x}[/tex] ( multiply both sides by x )
x × sin26° = 11 ( divide both sides by sin26° )
x = [tex]\frac{11}{sin26}[/tex] ≈ 25.1 ( to 1 dec. place )
"Correct" Answer:
53
Step-by-step explanation:
It's automadically 90 degrees because it's an acute angle, so you add 11 + 26 which gives you 37. Subtract 90 from 37 and it gives you 53, the variable.
26 + 11 = 37
90 - 37 = 53

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].
