5 video games bought.
Explanation:
Step one) identify all variables.
> y = money in bank acc AFTER buying (x) video games.
Step two) y = $40
Step three) substitute
> 40 = 90 - 10x.
Step Four) solve for x
> subtract 90 both sides.
-50 = -10x
DIVIDE by -10 on both sides ( to isolated x)
This equals 5 = x
x is number of video games bought meaning >> 5 video games bought

find the height of a with a cone with a diameter of 22 m whose volume is 113 m3.
Answer:
h=0.89
Step-by-step explanation:
Given
Diameter=22m
so radius=11m
Volume=113m^3
Solution
1/3πr^2h=113
1/3×3.14×11×11h=113
h=113×3/3.14×11×11
h=0.89
So the value of h is 0.89
Answer:
it's 3 m

help me plzzzzzzzzZz
Answer:
yes
Step-by-step explanation:
congruent means identical in form
Write this equation in standard form: (4, -1) m = 3
Standard form looks like this: Ax + By = C.
y - (-1) = 3(x - 4)
y + 1 = 3x - 12
y = 3x - 12 - 1
y = 3x + 13
Move 13 to left side and y to right side.
-13 = 3x - y
Done!

6. A recent Gallop poll showed Trump's approval rating 40% with a margin or error of 3%.
a) Find the confidence interval,
c) Does the confidence interval support that more than 50% of Americans approve of
Trump? Why or why not?
Answer:
Explained below.
Step-by-step explanation:
The (1 - α)% confidence interval for the population proportion is:
[tex]CI=\hat p\pm MOE[/tex]
Given:
[tex]\hat p=0.40\\MOE=0.03[/tex]
(a)
Compute the confidence interval as follows:
[tex]CI=\hat p\pm MOE[/tex]
[tex]=0.40\pm0.03\\\\=(0.37, 0.43)[/tex]
(b)
Since the confidence interval consists of values less than 50%, it implies that there is not enough evidence to suggest that more than 50% of Americans approve of Trump.
A home improvement store advertises 60 square feet of flooring for $287.00 including an $80.00 installation fee. How much does each square foot of flooring cost?
50 POINTS *GIVEING BRAINLIEST*
60 square feet= $287.00 + $80.00
= $367
1 square feet= $367 / 60
= $6.116666667
= $6.12 (to 2dp) ( answer)
Answer:
60 square feet for 287 = 287/60 = 4.78 per square foot
so ur equation would be : y = 4.78x + 80

How many 5-digit numbers are there in which three of the digits are 6, or two of
the digits are 9 ?
Answer:
The value is [tex]Z = 80[/tex]
Step-by-step explanation:
From the question we are told that
The total number of digit is n = 5
The total possible number of 6 is k = 3
The total possible number of 9 is a = 2
Generally the number of way of representing a 5 digits number(i.e the number of five digit numbers ) in which 3 of the digit are 6 is mathematically represented as
[tex]N = ^ nP_k[/tex]
Here P stands for permutation hence we are going to be making use of the permutation function in our calculators
[tex]N = ^ 5P_3[/tex]
=> [tex]N = 60[/tex]
Generally the number of way of representing a 5 digits number(i.e the number of five digit numbers ) in which 2 of the digit are 9 is mathematically represented as
[tex]M = ^ nP_a[/tex]
[tex]M = ^ 5P_2[/tex]
=> [tex]M = 20[/tex]
Generally the number of 5-digit numbers there are in which three of the digits are 6, or two of the digits are 9 is mathematically represented as
[tex]Z = M + N[/tex]
=> [tex]Z = 60 + 20[/tex]
=> [tex]Z = 80[/tex]
