Which equation would you use to find the total cost,
T, of the gym membership for m months?
1. T=30m+25
2. T=15m
3. T=30m+15
4. T=45m

Answer:

Math class ends at 10:35 AM.

Step-by-step explanation:

To find the answer, you need to add 40 minutes to the timestamp if 9:55 AM. There are 60 minutes in an hour, so you add five minutes to get to 10:00. 40-5=35. Now add 35 minutes to 10:00. The answer is 10:35 AM.

Answer:

The answer is 10:35 AM.

Step-by-step explanation:

Here, we know that in one hour there's 60 minutes.

1 hour = 60 minutes.

So, add 40 minutes in 9:55

9:55 + 40 minutes = 10:35 AM

Thus, Mr Gleasons math class will end at 10:35 AM.

The required number of bricks is 2990. None of the options are correct.

Given that,
Marcus builds a brick wall that is 23 bricks across and 130 bricks high. Which is the best estimate of how many bricks Marcus will use to build the wall is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Number of bricks in a row = 23
Number of bricks in column = 130
Total number of bricks = 23 * 130
                                      = 2990,

Thus, the required number of bricks is 2990. None of the options are correct.

The mean teaching year for all 218 teachers at High School A is 7.73 if the teaching year is recorded as an integer, with first-year teachers recorded as 1, second-year teachers recorded as 2, and so on.

It is defined as the numerical data representation in the graph with the help of a bar without space. The histogram gives an idea about the data's approximate distribution.

We have two histograms representing the teaching year with frequency.

From the first histogram the two reactangles represents = 45+48 = 93

From the second hisogram = 79+34 = 113

Median divided into two equal parts.

From the data:

The first graph has 200 points

The second graph has 221 points

The first graph median should be near the 100th data point

The second graph median should be the 111th data point

We obtain 93 from rectangles on a, which is less than 100, and these two rectangles include 1-4 and 4-7 (not including?) As a result, we might argue that this data covers 1-6.

We clearly need more values after we reach the medians, thus we must include the following interval. As a result, in a medium, 7 should be used.

The same reasoning applies to b), where the first two rectangles yield 113 and the median is the 111th datum point. We don't need to add these two rectangles because it includes them. So, for this median, the next interval (7-10) must be 6.

For part (b):

Mean of 18 = 2.5

= 2.5×18 ⇒ 45

Mean of 200 = 8.2

= 200×8.2 ⇒ 1640

New mean = Total/number of observation

= (45+1640)/(200+18)

= 1685/218

= 7.729

= 7.73

Thus, the mean teaching year for all 218 teachers at High School A is 7.73 if the teaching year is recorded as an integer, with first-year teachers recorded as 1, second-year teachers recorded as 2, and so on.

The domain of the function is [-5,0) and the range of the function y = startroot x 5 endroot is [0,∞)

Range of a function is the set of all the possible output values which are valid for that function.

The function given in the problem is,

[tex]y=\sqrt{x+5}[/tex]

This function is defined when the value of √(x+5) is greater than or equal to 0.

[tex]\sqrt{x+5}\ge0[/tex]

Solve it further,

[tex]\sqrt{x+5}\ge0\\(x+5)\ge0\\x\ge-5[/tex]

Thus, the domain of the equation is [-5,0). Now for the range,

[tex]x+5\ge0\\\sqrt{x+5}\ge0\\y\ge0[/tex]

Thus the range is  [0,∞).

Hence, the domain of the function is [-5,0) and the range of the function y = startroot x 5 endroot is [0,∞)

Answer:

Step-by-step explanation:

There are 8 different ways that the order of the children is 1/8 for each one.

So for boy * boy * boy = 1/2 * 1/2 * 1/2 = 1/8

All of the other possibilities also produce 1/8 because each child has a possibility of 1/2 to be a boy or a girl.

x=30

Step-by-step explanation:

you would call those alternate exterior angles meaning that they are the same angle, so all you have to do is reverse the equation meaning you do 75-15=60 and you would then divide by 2 to get X so 60/2=30, so x=30

Answer:

x = 30

Step-by-step explanation:

2x+15 should be vertical to angle 5

75 is vertical to angle 4.

If we were to look at angles 4 and 5 those are alternate interior which means they have to be congruent.

2x+15=75

2x=75-15

2x=60

x=30

Answer:

x-intercept : (-1.2,0) 

y-intercept : (0,-0.7)

Step-by-step explanation:

Hello!

An x-intercept is when the y-value is 0, and a y-intercept is when the x value is 0.

Another way to think about it, x-intercepts intersect with the x-axis, while the y-intercept intersects with the y-axis.

A coordinate, a point on a graph, is written as (x,y) or x-position and y-position.

x-intercept : (-1.2,0)  

y-intercept : (0,-0.7)

hope this helps <3

Answer:

452.39

Step-by-step explanation:

Step-by-step explanation:

a) x + 4 = 12

=> x + 4 - 4 = 12 - 4

=> x = 8

d) - 14 = 2x

=> -14/2 = 2x/2

=> -7 = x

x = -7

b) x + 5,1 = x + x

1 = x + x

1 = 2x

1/2 = 2x/2

x = 1/2 or 0.5

e) 5 = 4x

=> 5/4 = 4x/4

=> x = 5/4 or 0.8

c) 6x = x - 15

=> x - 15 = 6x

=> -15 = 6x - x

=> -15 = 5x

=> -15/5 = 5x/5

=> x = -3

f) x + 8 = 2x + 3

x+8=2x+3

x+8−2x=2x+3−2x

−x+8=3

−x+8−8=3−8

−x=−5

−x/−1 = −5/−1
