Answer:
Angela is 12 and Micah is 28.
Step-by-step explanation:
So, the problem tells us that Micah is four more than twice Angel's age, and the sum of both their ages is 40. So, if we use a to stand for Angela's age and m to stand for Micah's age, we can safely assume our equation will look like this:
(a × 2) + 4 = m. And once that is figured out, we use a + m = 40.
For right now, we can start just randomly entering in numbers for a. Let's try 10, for example.
(10 × 2) + 4 = 24.
But does 10 + 24 = 40? No, it equals 34. So we go higher.
(12 × 2) + 4 = 28.
Does 12 + 28 = 40? Yes, yes it does.
So we can say with all certainty that Micah is 28 years old, and Angela is 12.

The median of the given data is equal to 104. The correct option is B.
What is the median?The median is the value that separates the upper and lower halves of a data sample, population, or probability distribution in statistics and probability theory. It is sometimes referred to as "the middle" value in a data set.
Given that the data set is 99, 100, 105, 104, 102, 105, 105, 121, and 104. To calculate the median arrange the data in increasing order.
99,100,102,104,104,105,105,105,121
The median will be the middlemost value of the data set, Here in the above data set the middle value is 104. Hence the median is 104

How long would it take for a car to travel 200 km if it has an average speed of 55 km/hr?
Answer:
11,000 km/hr
Step-by-step explanation:
Distance= speed x time
time= 55 km/hr
speed= 200 kn
=200 km x 55 km/hr
= 11,000 km/hr
At an average speed of 55 km/hr the car will cover a distance of 200 km
in 3.6 hours.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
We know, distance = speed×time or d = st.
Given, A car to travel 200 km if it has an average speed of 55 km/hr.
Therefore, From d = st we have,
200 = 55t.
t = 200/55.
t = 3.6 hours.
What is the relative speed between two moving objects?The relative speed is the net speed of two different objects with respect to each other.
If two objects move in the same direction we take the difference between their speeds.
If two objects move in the opposite direction we take the sum of their speeds.

Complete the division problem by determining the number that should be placed in the box. Division bracket with 12 on the left, 5496 inside, and 458 above it. Underneath the 5496, there is a minus 4800. Then there is a solid line with 696 under the line. There is a minus sign, and an empty box followed by a solid line. Beneath the line, there is a 96 minus 96 underneath. There is a solid line and a 0 to end the problem. (4 points)
Answer:
600
Step-by-step explanation:
Just below the solid line, there is the remainder and just above the solid line, there is a multiple of 12.
The number with a negative sign is being subtracted to the above number.
The first subtraction is mentioned as
5496-4800=696, observe that 696 is just below the solid line.
Now, proceeding further in the same way, the number below the second solid line is 96 which is obtained when the number in the box is being subtracted to the above number 696.
Let the number in the box is [tex]x[/tex]. So,
[tex]696-x=96[/tex]
[tex]\Rightarrow x=696-96=600[/tex]
Hence, the required number in the box is 600.

The ratio of men to women at a business office is 6:13. There are 95 people working at the company. 9. 10. How many more women are there then men?
the ratio is 6:13 meaning 6 is for men and 13 is for women so add 6 and 13 to get 19 . since the total number of people was 95 it will be represented by the total ratio 19 then to get the number of men it will be 6 times 95 then divide by 19 for women 13 times 95 then divide by 19 after that subtract men from women

Kelly bought 8 boxes of sunglasses at a swap meet. Each box had 15, 20, or 25 pairs in it. Kelly estimates a reasonable number of sunglasses to be 110.
Is this a reasonable estimate?
Answer:
NO
Step-by-step explanation:
Because 8 * 15 = 120 so even if they all had 15 in hem here would be at LEAST 115
No. The reason is that if all the boxes had even 15 pairs in them, the least amount, it would be 120 not even 110. An ideal estimate would be something in between 200 and 120.

(-1,-2) would result in a relation that is no longer a function.
In the table, there's already x = -1 and y = -4. Function only gives a single y-value with x-value. If a single x-value gives two y-values then it'd not be Function.
If we add (-1,-2) in the table. The domain will be repetitive. Basically, we already have (-1,-4) and if we add (-1,-2) in the table, a single x-value will give TWO y-values which is not a function.

If 5 of mathjuce contain 120grams of sugar how many grames of suger are in a case of 24 cans of mathjuce
Answer: 576 grams of sugar
Explanation: To solve this, you must do this following. First, you'd need to divide the 5 cans of MathJuice by their grams of sugar content. By doing this, you will find out how many grams of sugar are in each can. So, you'd divide 120 by 5 and get 24. This means that there are 24 grams of sugar in each can. Now, you'd need to multiple that by the number of cans in a case of MathJuice. You need to multiply 24 by 24. Doing this will get you a product of 576. Therefore, there are 576 grams of sugar in a case of MathJuice.
I hope this helped!

Write an equation of the line through the point (-3,-8) and perpendicular to the line x = -7.
The slope of the x = - 7 equals infinite...
We know that the slopes of the perpendicular lines are inverse and symmetrical to each other ;
So ;
[tex](slope) \times \infty = - 1[/tex]
[tex]slope = - \frac{1}{ \infty } \\ [/tex]
[tex]slope = 0[/tex]
This the slope of the line.....
_________________________________
We have following equation to find the line :
[tex]y - y(through \: point) = (slope) \times ( \: x - x(t \:p) \: ) \\ [/tex]
Now just need to put the coordinates and the slope ;
Look :
[tex]y - ( - 8) = 0 \times (x - ( - 3))[/tex]
[tex]y + 8 = 0[/tex]
[tex]y = - 8[/tex]
And we're done....
Thanks for watching buddy good luck.
