what is the length of AC

Answer:

10x=y.

Step-by-step explanation:

10 represents the amount he earns an hour. X represents the number of hours so 10x. 10 times the amount of hours equals y (total amount of money)

Answer:

y = 10x

Step-by-step explanation:

The total earnings, y, is equal to the hourly rate, 10, times x, the hours worked.

y equals 10 times x, or, in equation form, y = 10x.

Answer: 170 people paid GH¢20 and 180 people paid GH¢30

Step-by-step explanation:

Let the number of people that paid GH¢20 be represented by x.

Let the number of people that paid GH¢30 be represented by y.

Based on the above information given, we can form an equation which will be:

x + y = 350 ....... i

20x + 30y = 8800 ....... ii

Multiply equation i by 20

20x + 20y = 7000 ...... iii

20x + 30y = 8800 ...... iv

Subtract iii from iv

10y = 1800

y = 1800/10

y = 180

Since x + y = 350

x = 350 - y.

x = 350 - 180

x = 170

Therefore, 170 people paid GH¢20 and 180 people paid GH¢30

Answer:

sample mean

Step-by-step explanation:

Using the normal distribution and the central limit theorem, considering that this is a sample proportion, as we are dealing with percentages, it is found that there is a 0.1562 = 15.62% probability of getting less than 50% Democrats in a random sample of size 100.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

The mean and the standard deviation of the sampling distribution of sample proportions are given by:

[tex]\mu = p = 0.55[/tex]

[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.55(0.45)}{100}} = 0.04975[/tex]

The probability of getting less than 50% Democrats in a random sample of size 100 is the p-value of Z when X = 0.5, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.5 - 0.55}{0.04975}[/tex]

[tex]Z = -1.01[/tex]

[tex]Z = -1.01[/tex] has a p-value of 0.1562.

0.1562 = 15.62% probability of getting less than 50% Democrats in a random sample of size 100.

Answer: 4d + 3

Step-by-step explanation:

Megan's daughter's age = d

Based on the information given, since Megan's age is three years more than four times her daughter's age, this can be written mathematically as:

= (4 × d) + 3

= 4d + 3

Therefore, Megan's age is 4d + 3.

For example, if the daughters age is 7 years, Megan's age will be:

= 4d + 3

= 4(7) + 3

= 28 + 3

= 31 years

Answer:

-6+3[tex]\sqrt{2}[/tex] and -6-3[tex]\sqrt{2}[/tex]

Step-by-step explanation:

xy = 18

x+y = -12

y = -12-x

substitution method:

x(-12-x) = 18

-12x - x² - 18 = 0

-x² - 12x - 18 = 0

-(x² + 12x + 18) = 0

used quadratic formula:

(-12±√144 - 4(18)) ÷ 2

(-12 ± [tex]\sqrt{72}[/tex]) ÷ 2

(-12 ± 6[tex]\sqrt{2}[/tex]) ÷ 2

= -6 ± 3[tex]\sqrt{2}[/tex]

Answer:

if it was 29inches it would be 78.7

Step-by-step explanation:

The given altitude and the base length of the triangle can be used for

finding the lengths of the other two sides.

The perimeter of the triangle is approximately 73.0 inches

Reasons:

The altitude is the perpendicular bisector of the base of the triangle

Length of the altitude = 26 inches

Length of the base of the triangle, b = 18 inches

Required:

The perimeter of the triangle

Solution:

The base length of the two congruent triangles formed are [tex]\dfrac{18 \, cm}{2}[/tex] = 9 cm

each.

Therefore;

The length of the hypotenuse side, L, is given by Pythagoras's theorem as

follows;

L² = 9² + 26² = 757

The hypotenuse side, L = The length of the equal sides of the isosceles triangle

Therefore, the perimeter of the triangle, P = b + 2·L

Which gives;

To the nearest tenth, the perimeter of the triangle, P = 18 + 2·√(757) ≈ 73.0

The perimeter of the triangle, P ≈ 73.0 inches

Answer:

2) A = 12 in.²

5) A = 737 in.²

6) A = 48 in.²

9) A = 2400 in.²

Step-by-step explanation:

2)

Trapezoid

base1 = 4 in.

base2 = 2 in.

height = 4 in.

A = (b1 + b2)h/2 = (4 + 2)(4)/2 = 12

A = 12 in.²

5)

rectangle + semicircle

A = LW + ½πr²

A = 29 * 20 + ½(3.14)(10²)

A = 580 + 157

A = 737 in.²

6)

A = 8 * 8 - 4 * 4

A = 48 in.²

9)

A = 50 * 60 - 20 * 30

A = 2400 in.²
