Answer:
n = (7/3)t
Step-by-step explanation:
Represente the unknown number by n. Then write the statement symbolically, as:
(3/7)n = t
and then solve the above equation for n by multiplying both sides by (7/3):
n = (7/3)t
1. −4n−8=4(−3n+2)
2. a−15=4a−3
what is the solution for 1 and what is the solution for 2
Answer:
n = 2 and a = - 4
Step-by-step explanation:
(1)
- 4n - 8 = 4(- 3n + 2) ← distribute parenthesis
- 4n - 8 = - 12n + 8 ( add 12n to both sides )
8n - 8 = 8 ( add 8 to both sides )
8n = 16 ( divide both sides by 8 )
n = 2
(2)
a - 15 = 4a - 3 ( subtract a from both sides )
- 15 = 3a - 3 ( add 3 to both sides )
- 12 = 3a ( divide both sides by 3 )
- 4 = a

A jet ski depreciates at 11% of its original value each year. If the jet ski was $8,000 at its time of purchase, what is the value of the jet ski after 5 years?
Answer: $4467.25
Step-by-step explanation:
Exponential decay problem. 8000(0.89)^5.
100-11 = 89
89/100= 0.89, that is how we got the decimal.
Then, solve.
0.89 * 0.89 * 0.89 * 0.89 * 0.89 = 0.5584059449
0.5584059449 * 8000 = 4467.2475592
Round the decimal part to the nearest hundredth, which is $4467.25.

Step-by-step explanation:
What is the solution of the system of equations below?
y + 2x = 2
y + 4x = 0
F. (1, -4) G. (-1,-4) H. (-1, 4) I. (1, 4)
G
Solution:
Here,
y+2x=2
y=2-2x
Now,
Putting the value of y
y+4x=0
2-2x+4x=0
2+2x=0
2(1+x)=0
1+x=0
x=-1
Then,
Putting the value of x
y=2x-2
=2×-1-2
=-2-2
=-4
Hence,the solution is (-1,-4)
A wooden building has the shape of a
rectangular pyramid. The building's
base is 100 meters long and 50
meters wide. The height of each
triangular face is 40 meters. How
much wood was used to make the
entire building?
A 33,000 m²
B 13,000 m2
C 11,000 m2
D 6,000 m2
Answer:
B: 13000 m²
Step-by-step explanation:
To find how much wood is used, we will have to find the surface area of the wooden building.
Formula for surface area of a rectangular pyramid is;
SA = lw + l√(h² + w²/4) + w√(h² + l²/4)
We are given;
l = 100 m
w = 50 m
h = 40 m
Thus;
SA = (100 × 50) + 100√(40² + 50²/4) + 50√(40² + 100²/4)
SA = 5000 + 4717 + 3201.56
SA = 12918.56
Approximating to 2 significant figures gives;
SA = 13000 m²
What is the value of the expression below when y=5
4y2-7y-6
Answer and Step-by-step explanation:
Let's plug 5 in for y.
[tex]4(5)^{2} - 7(5) - 6\\\\\\\\4(25) - 35 - 6\\\\\\100 - 35 - 6 = 59\\\\\\[/tex]
The value of [tex]4y^{2} - 7y - 6[/tex] when y is equal to 5 is 59.
#teamtrees #PAW (Plant And Water)
Answer:
59
Step-by-step explanation:
You can just replace y with its value which is 5.
4y² - 7y - 6 = 4(5²) - 7(5) - 6
= 4 × 25 - 35 - 6
= 100 - 35 - 6
= 59

In ARST, the measure of ZT=90°, the measure of ZR=39°, and TR = 55 feet.
Find the length of ST to the nearest tenth of a foot.
Answer:
ST = 44.5 feet
Step-by-step explanation:
sing SOH CAH TOA to solve the problem;
Given
m<T = 90
m<R = 39 degrees
TR = 55feet
Required
ST = opposite to m<R
TR is the adjacent
tan theta = opp/adj
tan m<R = ST/TR
tan 39 = ST/55
ST = 55tan39
ST = 55*0.8098
ST = 44.5 feet

Answer:
7
Step-by-step explanation;
Rewriting our equation with parts separated:
4+1/7+2+6/7
Solving the whole number parts:
4+2=6
Solving the fraction parts:
1/7+6/7=7/7 (7/7 is a whole number) But first before simplifing, reduce the fraction, 7/7=1/1. Then 1/1=1.
Combining the whole and fraction parts:
(Solving the whole number parts - 6)
(Solving fraction parts - 1)
6+1 = 7Find the value of x.
Answer:
x=90°
Step-by-step explanation:
The inside angles in a triangle always add up to 180°.
So:
53°+37°=90°
180°-90°=90°
x=90°
Answer:
see below
Step-by-step explanation:
since the sum of angles in a triangle is 180 degrees
x + 53 + 37 = 180
x = 180 - 53 - 37
x = 90 degrees

Which quantity makes the equation true?
x + 3x + _______ = 7x
Answer:
Step-by-step explanation:
C) 3X
Answer: C. 3x
Step-by-step explanation:
Since x and 3x both have x, you can add them together to get 4x (if there is x by itself, it really means that there is one of it, so it would be 1x.)
Then, you subtract 7x by 4x, which gives you the answer, 3x. You could also solving it by asking yourself: What number plus 4x equals 7x, which would give you 3x.

Step-by-step explanation:
What is the minimum y-value after which the exponential function will always be greater than the linear function? y = 1 y = 3 y = 4 y = 5
Answer:
y = 4.
Step-by-step explanation:
I suppose that this question relates to the image that can be seen below.
In the image, the green line represents the exponential function and the blue line represents the linear function.
The y-value after which the exponential function will always be greater than the linear function is the y-value where bot graphs intersect, such that after that point, the blue line starts increasing fast, and is always above the green line.
In this case, this point is the second intersection, and we can see that this intersection happens in the point (2, 4)
Remember that the usual notation for points is (x, y).
Then the y-value after which the exponential function will always be greater than the linear function is y = 4.
