Answer:
a. y = 2x b. 32
Step-by-step explanation:
a, y = kx, where k is a non-zero constant
when x = 7, y = 14
14 = 7k
k = 2
The required equation is y = 2x
b. From(a), y = 2x
y = 2(16)
y = 32

The combined height of one fur tree and one pine tree is 21 meters. The higher of 4 fir trees stacked on top of each other is 24 meters taller that the one pine tree. How tall are the types of trees that Logan genetically engineered?
Answer: Fur tree = 6 meters, pine tree = 15 meters
Step-by-step explanation:
Lets say the height of one fur tree is x
the height of one pine tree is y
so x+y=21 and 4x=24
x = 6
y = 15
Arthur is organising his collection of dvds he has 135 altogether. The ratio of comedy films to action horror is 6 : 8 : 1
Answer: See explanation
Step-by-step explanation:
The number of comedy films will be:
= 6/(6+8+1) × 135
= 6/15 × 135
= 54 comedy films
The number of action films will be:
= 8/(6+8+1) × 135
= 8/15 × 135
= 72 action films
The number of horror films will be:
= 1/(6+8+1) × 135
= 1/15 × 135
= 9 horror films
A father is 20 years older than his son. Five years ago,he was three times as old as his son was.Find their present ages
Answer:
Dad=35, Son=15
Step-by-step explanation:
Well since the dad is 20 year older then the son we can call the son x and the dad x+20. Now five years ago the father was 3 times older then the so we construct the following equation:
x+20−5=3(x−5)
x+15=3x-15
x=15
So now we know that the sons age is 15 meanimg that since the dads 20 years older then him, his age is 20+15 which is 35!
Solve for b. b + 2 = 4.6
b=6.6
b=4.12
b=2.6
b=2.3
Answer:
b=2.6
Step-by-step explanation:
b+2=4.6
Subtract both sides by 2 to isolate b
b+2-2=4.6-2
b=2.6
Therefore, b is equal to 2.6.

find the value (s) of the variables (s) in each parallelogram.
Step-by-step explanation:
As we can see it is a parallelogram so here the diagonals bisect so
6y + 1 = 4y + 9
6y - 4y = 9 - 1
2y = 8
y = 8 / 2
y = 4
2x - 5 =x + 7
2x + x = 7 + 5
3x = 12
x = 12 / 3
x = 4
Hope it will help :)

triangle similarity i think ... picture included * SIN COS TAN
Answer:
d = 105tan(37°)Step-by-step explanation:
opposite (o) = d
adjacent (a) = 105
Angle A = 90 - 53 = 37°
Therefore,
the correct equation would be
tan(A°) = opposite/adjacent
tan(37°) = d/105
d = 105tan(37°) ✅d = 105 × 0.7535540501
d ≈ 79.12 units

c. What will her monthly
payment be if the term of
the loan is 72 months with
an APR of 3.5%?
9514 1404 393
Answer:
a) $15,779.70
b) $13,679.70
c) $210.92
Step-by-step explanation:
a) When tax is added, the total cost is ...
total = price × (1 +tax rate)
total = $14,775 × 1.068 = $15,779.70
__
b) The amount financed is the difference between the total cost and the down payment.
financed = total - down35
financed = $15,779.70 -2100 = $13,679.70
__
c) The monthly payment is found using the amortization formula. It can also be found using any of a number of financial calculators, spreadsheets, or apps.
A = P(r/12)/(1 -(1 +r/12)^-n) . . . . annual rate r, n monthly payments, principal P
A = $13,679.70(0.035/12)/(1 -(1 +0.035/12)^-72) ≈ $210.92

[tex]a^{2} + b^{2} = c^{2}[/tex]
(the hypotenuse has to be [tex]c^{2}[/tex])
[tex]9.2^{2} + b^{2} = 16.5^{2}[/tex]
[tex]84.64 + b^{2} = 272.25[/tex]
[tex]b^{2} = 187.61[/tex]
