Answer:
h = 5
Step-by-step explanation:
6/8 - h/8 = 1/8
Multiply each side by 8 to clear the fractions
8*(6/8 - h/8) = 1/8*8
6 - h = 1
Subtract 6 from each side
6-h-6 = 1-6
-h = -5
Multiply each side by -1
h = 5
Answer:
[tex]h = 5[/tex]
Step-by-step explanation:
Solve the equations:
[tex] \frac{6}{8} - \frac{h}{8} = \frac{1}{8} [/tex]
Reduce fractions to the lowest term by canceling the greatest common factor:
[tex] \frac{3}{4} - \frac{h}{8} = \frac{1}{8} [/tex]
Rerreange unknown terms to the left side of the equation:
[tex] - \frac{h}{8} = \frac{1}{8} - \frac{3}{4} [/tex]
Find the common denominator and write the numerator above common denominator:
[tex] - \frac{h}{8} = \frac{1 - 6}{8} [/tex]
Calculate the sum or difference:
[tex] - \frac{h}{8} = \frac{ - 5}{8} [/tex]
Reduce the greatest common factor on both sides of the equation:
[tex] - h = - 5[/tex]
Divide both sides of the equation by the coefficient variable:
[tex]h = 5[/tex]

can someone please help me i need to calculate the are of a trapezium which is 6cm 15cm 9cm, please help
Answer:
Step-by-step explanation: The parallel sides of a trapezium are called the bases and the distance between them is the height. Therefore if 6cm and 15cm are the bases and 9cm is the height, then the area is A= ½(b1+b2)×h, where b1 is 6cm and b2 is 15cm and h is 9cm. Therefore the Area= ½(6+15)×9=94,5cm.

C. 10 units to the right and 2 units up
D. 10 units to the right and 4 units up
Answer:
C, and D
Step-by-step explanation:
First you reflect over the line y=x (line goes diagonal from quadrant I to quadrant III)
The rule of reflecting over the y=x line is that point (x,y) becomes point (y,x)
For example, point C ( -4, 2), becomes C' ( 2, -4)
Second is a translation 10 units to the right and 4 units up from C'(2,-4) to C''(0, 12)

Which point would not be a solution to the system of linear inequalities shown below? y\ge x+5\hspace{50px}y\ge\frac{2}{3} x+6 y≥x+5y≥ 3 2 x+6 (12, 7) (-12, 1) (-12, 9) (-12, 6)
Answer:
(12,7) is not a solution
Step-by-step explanation:
Given
[tex]y\ge x+5\hspace{50px}y\ge\frac{2}{3}x + 6[/tex]
Required
Point that is not a solution
We have:
[tex]y\ge x+5\hspace{50px}y\ge\frac{2}{3}x + 6[/tex]
Substitute [tex]\frac{2}{3}x + 6[/tex] for y in the first inequality
[tex]\frac{2}{3}x + 6 \ge x + 5[/tex]
Collect like terms
[tex]\frac{2}{3}x - x \ge 5-6[/tex]
[tex]-\frac{1}{3}x \ge -1[/tex]
Solve for x (the inequality will change because we are to divide by a negative number_
[tex]x \le -1/-\frac{1}{3}[/tex]
[tex]x \le 3[/tex]
Without solving further, we can conclude that the first option is not a solution.
Because (12,7) implies that [tex]x =12[/tex]
Compare [tex]x =12[/tex] to [tex]x \le 3[/tex], then [tex]x \le 3[/tex] is false

Step-by-step explanation:
Each number 1 2 3 etc are counting by 5's. 11, five times is 55. It cannot be D because the shorter needle determines the hour and the longer one is on 11. It can't be A because counting by 5 starts with 1 not 12 it rotates clockwise not anti-clockwise. It can't be C because for it to be 50, it would need to be on the 10 not on 11.

Describe how you would factor x^2 + 10x - 24. Be specific.
Answer:
if u have more doubts feel free to ask :)
Step-by-step explanation:
x² + 10x -24
x² + 12x - 2x - 24
x(x + 12) -2(x + 12)
(x + 12) (x - 2)
Factors of 24 : ±1 , ±2 , ±3 , ±4 , ±6 , ±8 , ±12, ±24. Combination of +12 and -2 gives "10" the middle term also " 24"
Kelly is going two work two part-time jobs during the school year. When she works for her dad, she will make $8.00 per hour. When she works at a day care center, she will make $14.00 per hour. To pay her car payment, Kelly needs to make at least $84.00 a week and can work no more than 10 hours total per week. Write an inequality to represent the difference combinations of hours working for her dad,X, and hours working for the daycare center,Y, Kelly can work if she wants to earn at least $84 per week
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of hours Kelly works for her dad per week and y represent the number of hours Kelly works in the daycare center per week.
Since she wants to make $84 per week, hence:
8x + 14y ≥ 84 (1)
Also, she can work a maximum of 10 hours per week, hence:
x + y ≤ 10 (2)

There is a 30% chance of snow on each of the next three days. What is the probability of getting snow on one of these days?
Answer:
30%
Step-by-step explanation:
In a (Gallup poll, 26.6% of 5000 people reported a Body Mass Index (BMl) greater than 30, which is classified as obese. The 5000 people polled are a random sample of adults, aged 18 and older, from the United States population. Choose the correct interpretation for the 98% confidence interval for the proportion of the population who arc obese? A. The proportion of adults in the United States, aged 18 or older, who are obese is between 0.2515 and 0.2805. B. We are 98% confident the proportion of adults polled who are obese is between 0.2515 and 0.2805. C. In 98% of all samples, the proportion of adults polled who are obese will be between 0.2515 and 0.2805. D. We are 98% confident that the proportion of adults in the United States, aged 18 or older, who are obese is between 0.2515 and 0.2805.
Answer:
D. We are 98% confident that the proportion of adults in the United States, aged 18 or older, who are obese is between 0.2515 and 0.2805.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
26.6% of 5000 people reported a Body Mass Index (BMl) greater than 30
This means that [tex]\pi = 0.266, n = 5000[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.266 - 2.327\sqrt{\frac{0.266*0.734}{5000}} = 0.2515[/tex]
The upper limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.266 + 2.327\sqrt{\frac{0.266*0.734}{5000}} = 0.2805[/tex]
The correct interpreation is that we are 98% confident that the proportion of adults in the United States, aged 18 or older, who are obese is between 0.2515 and 0.2805, which means that the correct answer is given by option D.
