0.5y+7=5(0.2+1.5y) someone please help I got y=1.36 but its wrong
Answer:
y= 6/7
Step-by-step explanation:
0.5y + 7 = 5( 0.2 + 1.5y )
Get rid of the brackets first
0.5y + 7 = 1 + 7.5y
Move the like terms
0.5y + 7 - 7.5y = 1
0.5y - 7.5y = 1 - 7
Collect the like terms
-7y = -6
Divide both sides by -7 to get y on its own
y= -6/-7
A negative number divided by a negative number gives a positive number so
y = 6/7
Answer:
y=6/7 or 0.857 aprox.(0.86)
Step-by-step explanation:
[tex]0.5y+7=5(0.2+1.5y)[/tex]
[tex]0.5y+7=1+7.5y[/tex]
[tex]7.5y-0.5y=7-1[/tex]
[tex]7y=6[/tex]
[tex]y=6/7= 0.857[/tex]

Multiply (8 + 3i)(3 + 5i).
39 + 49i
9 + 49i
24 + 15i2
24 + 49i + 15i2
Answer:
It's the last option "24 + 49i + 15i^2"
Step-by-step explanation:
To solve you must do FOIL, (First, Outer, Inner, Last). To do this, you must do:
8 × 3 = 24 , 8 × 5i = 40i , 3i × 3 = 9i , and
3i × 5i = 15i^2 .
Don't forget to combine like terms.
Altogether: 24 + 49i + 15i^2 .
Picture does better job at explaining FOIL⤴⤴⤴
Hope this helps :)

Look at the arithmetic pattern shown here.
Select the Hint button to view a hint.
Using the variable n for the term, describe the sequence.
Answer:
[tex]a_{n}[/tex] = 10n
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 10 and d = a₂ - a₁ = 20 - 10 = 10 , then
[tex]a_{n}[/tex] = 10 + 10(n - 1) = 10 + 10n - 10 = 10n
The sequence can be seen to be an arithmetic sequence and the common difference of the sequence is 10.
What is an arithmetic sequence?Arithmetic sequences are an essential concept in mathematics and have applications in various fields, including algebra, physics, computer science, and finance. They are widely used to model patterns and relationships in real-world situations.
Looking at the sequence we can see that the common difference d can be obtained as;
d = S2 - S1
= 20 - 10
= 10
d = S3 - S2
= 30 - 20
= 10

A box is pulled to the right with a force of 65 N at an angle of 58 degrees to the horizontal. The surface is frictionless. The free body diagram is shown.
A free body diagram with 3 force vectors. The first vector is pointing north, labeled F Subscript N Baseline, the second vector is pointing south labeled F Subscript g Baseline = 30 N, and the third pointing 58 degrees north of east labeled F Subscript g Baseline = 65 N.
What is the net force in the x-direction?
30 N
34 N
55 N
65 N
Answer:
34 N.
Step-by-step explanation:
Net force in x direction = 65 cos 58
= 34 N.

√80+√20 find it ......
Answer:
Approximately 13.41
Step-by-step explanation:
First do square root of each, which is finding what number multiplies by its self to get the number.
For example: The square root of 80 is approximately 8.94, and the square root of 20 is approximately 4.47.
So: 8.94 + 4.47 = 13.41 (Add normally, but remember to put the decimal in the right place).

If a toy rocket is launched vertically upward from ground level with an initial velocity of 120 feet per second, then its height h after t seconds is given by the equation h(t) = -16t2 + 120t. How long will it take the rocket to return to the ground?
A) 7.5 seconds
B) 16 seconds
C) 3.75 seconds
D) 120 seconds
Answer:
A) 7.5 seconds
Step-by-step explanation:
Height of the ground is zero
-16t^2 + 120t = 0
Divide both sides by 16
-t^2 + 7.5t = 0
Factor out t
t(-t + 7.5) = 0
From the zero product rule
t = {0, 7.5}
0 would be time of launch
7.5 is time back to the ground
