Answer:
x = 10.
Step-by-step explanation:
(5x-1) + (8x+5) + (4x+6) = 180 (the 3 angles in a triangle sum to 180 degrees).
5x + 8x+ 4x - 1 + 5 +6 = 180
17x + 10 = 180
17x = 170
x = 10.
The height of a door is 1.8 feet longer than it's with its front area is 1496.9 ft.² find the width and height of the door
The width of the door is [tex]37.8ft[/tex] and the height of the door is [tex]39.6ft[/tex]
Let
[tex]A=\text{the front area of the door}\\h=\text{the height of the door}\\w=\text{the width of the door}[/tex]
From the question
[tex]A=w\times h=1496.9\\h=w+1.8[/tex]
We are to find both the width and the height of the door. To proceed, we have to eliminate the height, and solve for the width. Later, we calculate the value of the height from the width.
Eliminate the height;
[tex]A=w\times h\\A=w\times(w+1.8)\\w^2+1.8w-A=0[/tex]
substitute the value of the front area into the equation and solve for the width
[tex]w^2+1.8w-1496.9=0\\w\approx 37.8\text{ or }w\approx-39.6[/tex]
the width can only take positive value. Now, to get the height
[tex]h=w+1.8\\=37.8+1.8\\=39.6[/tex]
the width and height of the door are [tex]37.8ft[/tex] and [tex]39.6ft[/tex] respectively.

Emily borrows £580 from a bank at an interest rate of 896 per year.
She will give the money back after 4 years.
How much money will Emily have to pay back?
Answer: £4,164
Step-by-step explanation: multiply 896 by 4 to get £3,584 next add 580 to 3,584 to get £4,164
Answer: 4,164
Step-by-step explanation: I am confused if the 896 is a percent or the money she owes every year, now here is the explanation.
Emily took the £580 and after the 4 years she owes 896*4 = £3,584 plus the original £580 which is £4,164
If it it without the original £580 then the answer is 896*4 = £3,584
If that is not correct then i am sorry

Daisy had 2 3/4
bags of mulch to put in her yard. Each bag will cover 235.5 ft2
. How much square feet will she be able to cover is she uses all of the bags of mulch?
help me plsssssss
Answer:
mmmmmmm
Step-by-step explanation:
n
Daisy will cover a total area of 647.625 square feet, if she uses all of the bags of mulch.
The amount of mulch is given as:
[tex]Bag = 2\frac 34[/tex]
The area covered by each bag is given as:
[tex]Area = 235.5ft^2[/tex]
If she uses all bags, the total area covered by the bags is:
[tex]Total = Bag \times Area[/tex]
So, we have:
[tex]Total = 2\frac 34 \times 235.5ft^2[/tex]
Rewrite the fraction as an improper fraction
[tex]Total = \frac {11}4 \times 235.5ft^2[/tex]
This gives
[tex]Total = \frac {2590.5}4 ft^2[/tex]
[tex]Total = 647.625 ft^2[/tex]
Hence, she will be able to cover a total area of 647.625 square feet

5:2 and 30: 12
o equivalent
not equivalent
Answer:
yes
Step-by-step explanation:
Ratios are equivalent if they are multiples or divisors of each other.
5 : 2 ( multiply both sides by 6 )
= 30 : 12
or
30 : 12 ( divide both sides by 6 )
= 5 : 2
Thus 5 : 2 and 30 : 12 are equivalent ratios
Answer:
equivalent
Step-by-step explanation: 5 x 6 = 30 2 x 6 = 12
velocity question ht=2+31t-16tsquared
Answer:
Step-by-step explanation:
If I am not mistaken the equation is [tex]S(t) = 2 + 31t - 16t^{2}[/tex]
Then in that case V(t) = S'(t) = 31 - 32t
V(t)=0 gives the time when the stone hits the ground.
31 - 32t = 0
32t = 31
t = 31/32 = 0.96875s
