Answer:
Step-by-step explanation:
if we have a rectangle with W=90 and L=120, and we need to find the diagonal
we will have a right triangle with the legs 90,120
diagonal is the hypothenuse
c^2=90^2+120^2=8100+14400=22500
c=sqrt22500=150
the diagonal, c=150
2 1 Add the expressions 4- b +-a and a +-6-7. What is the simplified sum? 3 4 2 6 14 5 Q+b-3 6 3 1 b-3 2 4 3 5. a+2b-3 4 6 5 1 -6-3 6 12
Answer:
-b - 9
Step-by-step explanation:
First, since the a cancel eachother out we are left with (4-b) + (-6-7)
Second, you want to add the -6 and -7 to get -13, so (4-b) - 13
Finally, add the 4 to the negative 13 to get (-b - 9)
How many quarts of a 50% solution of acid must be added to 20 quarts of a 20% solution of acid to obtain a mixture containing a 45% solution of acid?
Answer Using the method of alligation. 40.0= 20/(10/20) qts of 50% solution to add to your 20 qts of 20% solution. 60.0= (20+40.0) qts of the final 40% solution.
the following m and m colors are in the bowl
4 yellow
6 orange
3 green
5 blue
2 brown
what is the probability of selecting a blue eating it then selecting a yellow
Answer:
probability of blue =5/20=1/4
Step-by-step explanation:
probability of yellow=4/20=1/5
Probability of selecting a blue colour then a yellow colour is, 1/19.
What is conditional probability?Conditional probability is a term used in probability theory to describe the likelihood that one event will follow another given the occurrence of another event.
Given, A bowl containing 4 yellow, 6 orange, 3 green, 5 blue, 2 brown colors.
Let P(A) be the probability of selecting a blue colour.
∴ P(A) = N(B)/N(S).
P(A) = 5/20.
P(A) = 1/4.
Let P(B) be the probability selecting a yellow colour is = 4/19.
As we replacement is not allowed.
∴ Probability of selecting a blue colour then a yellow colour is,
= P(B)×P(A).
= 4/19×1/4.
= 1/19.

A car was bought for £18,000.
It was sold for £15,300.
Express this as a percentage decrease.
Answer:
15%
Step-by-step explanation:
when 18000 is 100%, 10% is 1800. So to make 15300 we need 8.5 1800s. So 85% of 18000 is 15300 so the rest is 15%. The answer is 15%
Answer:
15%
Step-by-step explanation:
[ (18,000-15,300) / 18,000 ] x 100
= (27,00 / 18,000) x 100
= 0.15 x 100
= 15%

Which equation shows how the distributive property can be used to find the number of
Xs in both arrays?
Answer:
here is a simple version
lets make A equal the exponent so (A=^2 or 3 or whatever)
the exponent will be the amount of times you want to repeat the process.
Now lets make x = the first array, so x=3
and lets make y = the second array, y=7
now a simple equation would be (3x)(7y)^A or for this you could say
(3x)(7y)^6

-2x + 8 = y
3x - y = 22
How do I solve it
answer
x=6, y=-2
explanation
-2x + 8 = y -------equ 1
3x - y = 22 -------equ 2
u can use any of the simultaneous equation method
using elimination method
rearrange first from -------equ 1
-2x+8=y
-y-2x=-8
multiple through by -1
y+2x=8 -------equ 3
rearrange first from -------equ 2
3x-y=22
-y+3=22 ------equ 4
equate 3 and 4, adding them together
y+2x=8 -------equ 3
-y+3=22 ------equ 4
0+5x=30
5x=30
x=6------equ 5
replace 6 for x in any equation
using -------equ 3
y+2x=8
y+2(5)=8
y+10=8
y=8-10
y=-2
Answer:
(x, y)=(6, -4)
Step-by-step explanation:
-2x+8=y
3x-y=22
Substitute the given value of y into the equation 3x-y=22
3x-(-2x=8)=22
Solve the equation for x
x=6
Substitute the given value of x into the equation 3x-y=22
3x6-y=22
Solve the equation for y
y=-4
The possible solution of the system is the ordered pair (x, y)
(x, y)=(6, -4)
Check if the given ordered pair is the solution of the system of equations
-2x6+8=-4
3x6-(-4)=22
Simplify the equalities
-4=-4
22=22
Since all of the equalities are true, the ordered pair is the solution of the system
(x, y)=(6, -4)
