Gia can run 4 miles in 32 minutes. At that rate, how many miles can she run in 40 minutes
Answer:
5
Step-by-step explanation:
For these types of problems, we can use cross - multiplication.
4/32 = x/40
Notice that since 40 and 32 are both measured in minutes, we put them on the same line.
Now, like the name suggests, we cross multiply the equation, by doing 4 * 40 = 32 * x. Now, we are left with 160 = 32x. After solving this, we get the answer 5.
A plane is flying at a steady speed of 30000m/minute.
How long does it take to fly 2000m. Give your answer in seconds.
SHOW METHOD AND EXPLAIN
Answer:
4 seconds
Step-by-step explanation:
[tex]\frac{30,000}{1} =\frac{2,000}x}[/tex]
The numerator is the distance and the denominator is the time.
I used cross multiplication, the numerator of one fraction times the denominator of the other.
[tex]30,000*x=2,000*1\\30,000x=2,000[/tex]
divide both sides by 30,000 and simplify
[tex]x=\frac{2,000}{30,000} \\x=\frac{2}{30}[/tex]
Then multiply the fractions by 2/2 (basically multiplying the numerator and the denominator each by 2)
[tex]x=\frac{4}{60}[/tex]
Since the denominator is 60, the number of seconds in a minute, the numerator is the answer
I hope this makes sense ;-;
A line passes through the point (8, -9) and has a slope of 3/4 . Write an equation in point-slope form for this line.
Answer:
y+9=3/4(x-8)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-9)=3/4(x-8)
y+9=3/4(x-8)
Brian rolls a fair dice 60 times.
How many times would Brian expect to roll a three?
Answer:
10 times.
Step-by-step explanation:
He rolls all the dice independently, so The expected number of 3's is 60 * (expected number of 3's in one throw).
The expected number of 3's in one throw is:
5/6 * 0 + 1/6 * 1 = 1/6
because 5/6 of the time we roll zero 3's and 1/6 of the time we roll one 3 :D
So he should expect (60 * 1/6 = 10) 3's in 60 throws.

Patrick invested money into a special savers bank account.
Each year money in the account earns 4% interest.
After one year, the total amount of money in the account was £291.20
How much did Patrick invest?
Answer:
£280.0
Step-by-step explanation:
Given the following
Rate R= 4%
Time T = 1year
Amount = £291.20
Simple Interest I = ?
I = PRT/100
A = P+I
Since P = A-I
I = (A-I)RT/100
I = (291.2-I)RT/100
100I = (291.2-I)4
100I = 1,164.8-4I
104I = 1,164.8
I = 1,164.8/104
I = £11.2
Amount = P+I
Principal = A-I
P = 291.2-11.2
P = 280.0
Hence patrick invested £280.0

Answer:
1) (x - 2)² = 25 2) x = 2 ± 5Step-by-step explanation:
[tex]24 = x^2 - 4x + 3\\\\ x^2 - 4x + 3-24=0\\\\\underbrace{x^2-2\cdot x\cdot2+2^2}-2^2-21=0\\\\{}\qquad(x-2)^2-25=0\\\\{}\qquad\bold{(x-2)^2=25}\\\\{}\qquad x-2=\pm\sqrt{25}\\\\{}\qquad \bold{x=2\pm5}[/tex]
the required equation for 1 is (x - 2)² = 25 and solution for 2 is x = 2 ± 5
What is the equation?The equation is the relationship between variables and is represented as y =ax + b is an example of a polynomial equation.
part 1
Given equation,
x² - 4x + 3 = 24
x² - 4x + 4 - 4 + 3 = 24
(x - 2)² - 1 = 24
(x - 2)² = 24 + 1
(x - 2)² = 25
Part 2
Solution for the given equation that transformed in part 1 of the solution.
(x - 2)² = 25
(x - 2) = √25
(x - 2) = ±5
x = 2 ± 5
Thus , the required equation for 1 is (x - 2)² = 25 and solution for 2 is x = 2 ± 5

12. x = 15, y = 21
13. x = 10, M = 37, N = 84, P =59
14. x = 19, R = 43, S = 20, T = 117
15. A = 21, B = 125, C = 34
16. J = 48, K = 57, L = 75
Explanation
12. 6x - 11 + x + 5 + 81 = 180
7x + 75 = 180
7x = 105
x = 15
4y - 18 + y + 14 + 6*15 - 11 = 180
5y + 75 = 180
5y = 105
y = 21
13. 4x - 3 + 9x - 6 + 6x - 1 = 180
19x - 10 = 180
19x = 190
x = 10
M = 4*10 - 3 = 37
N = 9*10 - 6 = 84
P = 6*10 - 1 = 59
14. R = 2x + 5
S = x + 1
T = 7x - 16
2x + 5 + x + 1 + 7x - 16 = 180
10x - 10 = 180
10x = 190
x = 19
R = 2*19 + 5 = 43
S = 19 + 1 = 20
T = 7*19 -16
15. A = C -13
B = 4C - 11
c - 13 + 4c - 11 + c = 180
6c -24 = 180
6c = 2-4
C = 34
A = 34 - 13 = 21
B = 4*34 - 11 = 125
16. K = J + 9
L = 2J -21
j + 9 + 2j - 21 + j = 180
4j -12 = 180
4j = 192
J = 48
K = 48 + 9 = 57
L = 2*48 -21 = 75
