Answer:
[tex] \frac{1}{2} \: or \: 0.5 [/tex]
Step-by-step explanation:
[tex] \frac{5}{7} \times \frac{14}{20} = \frac{5 \times 14}{7 \times 20} [/tex]
It can be also written as -
[tex] = > \frac{5 \times 14}{20 \times 7} = \frac{5}{20} \times \frac{14}{7} = \frac{1}{4} \times 2 = \frac{1}{2} [/tex]
Write x^2-8x+22 in the form (x-a)^2 +b
Answer:
[tex] {(x - 4)}^{2} + 6[/tex]
Step-by-step explanation:
[tex] {x}^{2} - 8x + 22 \\ \\ = {x}^{2} - 8x + 16 + 6 \\ \\ = {x}^{2} - 8x + {4}^{2} + 6 \\ \\ = {(x - 4)}^{2} + 6[/tex]
The completed square form of x² - 8x + 22 = 0 is (x - 4)² = - 6.
What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as its degree is two.
Given, a quadratic equation x² - 8x + 22 = 0.
We know (a - b)² = a² - 2ab + b².
∴ x² - 8x + 22 = 0 is
(x)² -2(x)(4) + 4² + 6 = 0.
(x - 4)² = - 6.

a baker needs 3/5 cup of water 2/3 cup flour using this ratio how much flour is needed for 1/3 cup water?
10/27 cup
3/10 cup
2/15 cup
1/36 cup
Answer:
10/27 cups
Step-by-step explanation:
y = how much flour is needed
set up proportion of water to flour equals water to flour
[tex]\frac{3/5}{2/3}[/tex] = [tex]\frac{1/3}{y}[/tex]
cross-multiply: 3/5 y = 2/9
multiply each side by the reciprocal of 3/5
5/3 · (3/5)y = 2/9 · (5/3)
y = 10/27
Answer: 10/27 cups flour.
Step-by-step explanation:
Compare fractions 3/5 and 1/3:
[tex]\dfrac{3}{5}=\dfrac{3 \times 3}{5 \times 3} =\dfrac{9}{15} \\\\ \dfrac{1}{3}=\dfrac{1 \times 5}{3 \times 5} =\dfrac{3}{15}\\\\\dfrac{3}{15} < \dfrac{9}{15}[/tex]
1/3 is less than 3/5 because 3/15 is less than 9/15.
Find how many times 1/3 is less than 3/5:
[tex]\dfrac{3}{5} \div \dfrac{1}{3} =\dfrac{3}{5} \times \dfrac{3}{1}=\dfrac{9}{5}[/tex]
This means that flour should also be taken 9/5 times less:
[tex]\dfrac{2}{3} \div \dfrac{9}{5} =\dfrac{2}{3} \times \dfrac{5}{9} =\dfrac{10}{27}[/tex]

X – y=11
3x + 10y= -6
Answer:
(8, - 3 )
Step-by-step explanation:
Given the 2 equations
x - y = 11 → (1)
3x + 10y = - 6 → (2)
Multiplying (1) by 10 and adding to (2) will eliminate the y- term
10x - 10y = 110 → (3)
Add (2) and (3) term by term to eliminate y
13x + 0 = 104
13x = 104 ( divide both sides by 13 )
x = 8
Substitute x = 8 into either of the 2 equations and solve for y
Substituting into (2)
3(8) + 10y = - 6
24 + 10y = - 6 ( subtract 24 from both sides )
10y = - 30 ( divide both sides by 10 )
y = - 3
solution is (8, - 3 )

Step-by-step explanation:
Since the degree of the angle is 45, we know that the triangle is isosceles. That means that the sides of the triangle, not including the hypotenuse, has a length of 3√2.
Using the Pythagorean theorem, which is a^2 + b^2 = c^2, we have (3√2)^2 + (3√2)^2 = c^2.
Note: c is the hypotenuse of the triangle.
18 + 18 = c^2
= 36 = c^2
Therefore, c = 6.
In a survey of 2,800 people who owned a certain type of car, 1,540 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
55%
Step-by-step explanation:
Calculation for What percent of the people surveyed were satisfied with the car
Percentage of people satisfied=1,540 people/2,800 people
Percentage of people satisfied=0.55*100
Percentage of people satisfied=55%
Therefore the percent of the people surveyed were satisfied with the car is 55%

Fractions are integers that have both a numerator and a denominator. Fraction comes in the form: [tex]\frac{x}{y}[/tex]
where x = numerator and y = denominator.
a) 1/5 + 3/4
We find the Lowest common denominator (5, 4) = 20
Hence: 4 + (5 x 3) / 20
= 4 + 15 / 20
= 19/20
b) 7/9 - 3/5
We find the Lowest common denominator (5, 9) = 45
Hence: (7 x 5) + (9 x 3) / 45
= 35 - 27 / 45
= 8/45
c) 6/8 - 2/7
We find the Lowest common denominator (7, 8) = 56
Hence: (6 x 7) - (2 x 8) / 56
= 42 - 16 /56
= 26/56
= 13/28
d) 5/6 + 5/10
We find the Lowest common denominator (6, 10) = 30
Hence: (5 x 5) + (5 x 3) / 30
= 25 + 15 / 30
= 40/30
= 4/3
= 1 1/3
e) 7/8 - 2/3
We find the Lowest common denominator (3, 8) = 24
Hence: (7 x 3) - (2 x 8) / 24
= 21 - 16 / 24
= 5/24
f) 8/10 + 5/6
We find the Lowest common denominator (6, 10) = 30
Hence: (8 x 3) + (5 x 5)
= 24 + 25 / 30
= 49/30
= 1 19/30
g) 9/11 - 2/3
We find the Lowest common denominator (3, 11) = 33
Hence: (9 x 3) - (11 x 2) / 33
= 27 - 22 / 33
= 5/33

The probability of getting a 6 is 4/5. The dice is rolled 500 times How many sixes would you expect to roll
Answer: 400
Step-by-step explanation:
From the question, we are informed that the probability of getting a 6 is 4/5 and that the dice is rolled 500 times.
The number of sixes that would be expected to roll will be 4/5 multiplied by the number the dice is rolled
= 4/5 × 500
= 400
There'll be 400 sixes.
