Answer:
25%
Step-by-step explanation:
Let v, t be the current average speed and the time taken to reach the school respectively.
As distance = speed x time, so,
distance, d=vt...(i)
Let V be the new average speed in order to to take 20% less time than t.
So, time taken with speed V = t-20% of t = t- 0.2t= 0.8t
As distance is constant, so
d= V(0.8t)= 0.8Vt
hBy using equation (i), we have
0.8Vt = vt
0.8 V = v
V= v/0.8=1.25v
Therefore, the percentage increase in the average speed = [tex]\frac{V-v}{v}\times 100[/tex]
[tex]=\frac{1.25v-v}{v}\times 100[/tex]
=25%
Hence, the percentage increase in the average speed is 25%.
Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses whenever possible.
d. The opposite of - 10t and t - 10t
Answer:
The answer is t.
Step-by-step explanation:
We need to find the sum of opposite of - 10t and t - 10t.
Opposite of -10t = 10 t
So,
10t + (t-10t)
Grouping the numbers,
(10t+(-10t)) + t
= 0 + t
= t
Hence, the answer is t.

Step-by-step explanation:
is that what you were asking?
x + 5y = -27
-2x - 5y = 24
Answer:
Step-by-step explanation:
x+5y=-27
-2x-5y=24
If the signs are the same u minus if they are different u add
So they are different were gonna add
x+5y=-27
-2x-5y=24
-1=-3
You cant divide it further x=-3
Next were gonna subsitute in any equation
x(-3)+5y=-27
-3+5y=-27
+3 to -27
-7+3=-24
5y=24
24/5=4.8 y=4.8

A bag contains 16 coins consisting of
dimes and nickels. The total value of
coins is $1.30. How many of each
type of coin are there?
Answer:
Dimes: 10 dimes
Nickles: 6 nickels.
Step-by-step explanation:
Dimes: 10 x 0.10 = 1.00
Nickels: 6 x 0.05 = 0.30
$1.00 + $0.30 = 1.30
Select all factors of the following polynomial: 5p3 + 45p2 + 40p
Answer:
[tex]\huge\boxed{5p;\ (p+1)}[/tex]
Step-by-step explanation:
[tex]5p^3+45p^2+40p=5p(p^2+9p+8)=5p(p^2+p+8p+8)\\\\=5p\bigg[p(p+1)+8(p+1)\bigg]=5p(p+1)(p+8)\\\Downarrow\\\boxed{5p};\ \boxed{(p+1)};\ \boxed{(p+8)}[/tex]
the factors for the given expression are
[tex]5p, p+1, p+8[/tex]
Given :
Given expression is [tex]5p^3 + 45p^2 + 40p[/tex]
Lets factor the given trinomial by factoring out GCF that is greatest common factor
Lets find out GCF from the given expression
all the terms are divisible by 5 and also we have 'p' in common
so GCf is 5p
[tex]5p^3 + 45p^2 + 40p\\5p\left(p^2+9p+8\right)\\[/tex]
Now we factor [tex]\left(p^2+9p+8\right)[/tex]
Product is 8 and sum is 9
So factors are 8 and 1
[tex]5p\left(p^2+9p+8\right)\\5p\left(p+1\right)\left(p+8\right)[/tex]
So the factors are
[tex]5p, p+1, p+8[/tex]

Answer: ↓↓↓
Step-by-step explanation:
Part A
131.5 or $131,500 is the starting value of the plane X before it started to depreciate.
Part B (They meant plane Y as in plane Y but plane B as in the second plane, look at the table and Part C)
b (m) = 177,233 (0.024)^m
$177,233 is the starting value of plane Y.
The value depreciates by 2.4% and that is the same as 0.024, except 0.024 is in decimal form.
Part C
b (t) = 177,233 (0.024 x 12)^t
b (t) = 177,233 (0.288)^t
I multiplied 12 by the depreciation because for the whole equation to actually show the depreciation in years I had to solve how much the plane would depreciate in 1 year. So, since 12 months is 1 year, I multiplied 12 by 0.024.
That's it! I hope I'm right because this took a lot of thinking lol

We need to write the equivalent expression for the above expression.
Taking like terms together,
[tex]=(\dfrac{3x}{5}+\dfrac{3x}{5})+\dfrac{2}{5}\\\\=\dfrac{3x+3x}{5}+\dfrac{2}{5}\\\\=\dfrac{6x}{5}+\dfrac{2}{5}\\\\=\dfrac{6x+2}5}[/tex]

A number, rounded to 2 decimal places, is equal to 3.84.
Write down the lower and upper bounds of the number.
Answer:
Lower bound = 3.835
Upper bound = 3.844
Step-by-step explanation:
Given,
A number rounded to 2 decimal place = 3.84
In other to obtain the least and greatest number, we are mostly concerned about the third digit after the decimal point.
Knowing that numbers 5 and above are rounded to 1 while numbers below 5 are rounded to Zero.
Hence, the lower bound should have its original hundredth value as (4 - 1) such that it becomes 4 when the thousandth value is rounded to 1.
Lower bound = 3.835
The upper bound should have its thousandth value as one which is rounded to Zero, just a point below 5
Upper bound = 3.844
You make 9 quarts of tomato sauce from 6 baskets of tomatoes.
What is the ratio of quarts to baskets in simplest form?
Answer:
3/2
