B. Solve;
1. Find a number such that three times the sum of that number
and 5 is greater than 33.

2. The sum of two consecutive integers is less than 81. Find the
pair of integers with the greatest sum.​

Answers

Answer 1
1 .
Let’s say your number is x.
3x+5>33
3x>28
x>28/3
2.
Let’s say the two consecutive integers are x and x-1
Since the two numbers are integers and two consecutive numbers (odd+even) can never add up to an even number (80 for example).
The highest possible sum of two consecutive integers that is less than 81 will add up to 79.

x+x-1=79
2x-1=79
2x=80
x=40
So the two consecutive numbers are 40 (x) and 39(x-1)
Hope this helps

Michael uses a blend of dark chocolate and milk chocolate to make the ice cream topping at his restaurant. He needs to buy 100 kg of chocolate in total for his next order. Dark chocolate costs $12 per kilogram, milk chocolate costs $10 per kilogram, and he wants to spend $1120 total.

Let d be the number of kilograms of dark chocolate he buys and m be the number of kilograms of milk chocolate he buys.

Which system of equations represents this situation?

Answers

Answer:

d + m = 100

12d + 10m = 1120

Step-by-step explanation:

d = 60

m = 40

Answer: 60 kg dark chocolate, 40 kg milk chocolate

Step-by-step explanation:

Okie soooo

Let's name the variables (which they did for us lol)

d = kg of dark chocolate and m = kg of milk chocolate

He needs 100 kg of chocolate

d + m = 100

and he wants to spend 1120 when dark chocolate costs $12/kg and milk chocolate costs $10/kg

12d + 10m = 1120

Now we solve the system (I shall use elimination method)

Multiply the first equation my -10

-10(d + m) = (100)(-10)

which becomes

-10d - 10m = -1000

12d + 10m = 1120 (rewrite the second equation)

------------------------- (add the two equations together)

2d = 120

d = 60

now substitute d into either equation

60 + m = 100

m = 40

60 kg dark chocolate

40 kg milk chocolate

What is perimeter of the semi circle?

Answers

Answer:

54.22 mm

Step-by-step explanation:

Find the circumference of the circle and then divide it by 2.

We start with the formula for the circumference for the circle:

C = 2πr

To find r, divide 22 by 2:

22/2=11

Now find the cicumference:

C = 2πr = 2(3.14)(11) = 108.46 mm

NOW, to find the perimeter of the semicircle, divide the circumference by 2:

108.46/2 = 54.22 mm

Write the SLOPE INTERCEPT FORM of the equation of the line parallel to y=23x+19 through the point (6, 2). First to answer correctly gets brainliest!

Answers

Answer:

y = 23x - 136

Step-by-step explanation:

Since the lines are parallel, they have the same slope. So, the slope of the new line is 23 as well.

Now we have: y = 23x + b

plug in the points that are on this line (6,2) :

2 = 23 x 6 + b

2 = 138 +b

-136 = b

Line: y = 23x - 136

A council reviews the number of bedrooms in 40 houses located in the same area. The table shows the information gathered. Find the modal average number of bedrooms. Work out the mean number of bedrooms

Answers

Mode is the most frequent number, in this case, 3 bedrooms appears 15 times. As a result 3 is the mode.
Doing the mean, is the same as providing a weighted average of bedrooms, with the weights being the frequency a given number of bedrooms appears at. As such, I need to multiply each element of the first column with the respective element of the second column. For example, for 1 bedroom, I have 1 x5 = 5; for 2 bedrooms I have 2x10 =20; if we do this across all number of bedrooms, and then add it all up, we get 113. We then divide this 113, by the number of flats being surveyed ie 40. This gives an average (or mean) of 2.825

The modal average number of bedrooms is 3, while the mean number of bedrooms is 2.825.

What is Mean?

A mean is an arithmetic average of a set of observations. it is given by the formula,

Mean = (Sum of observations)/Number of observations

A.) The modal average number is a mode of a given data set. Now, if the mode of the given data is needed to be taken then we need to observe the row that has the highest frequency.

Therefore, the modal average number of bedrooms is 3.

B.) The mean number of bedrooms can be found as shown below.

Mean number of bedrooms = (1×5 + 2×10 + 3×15 + 4×7 + 5×3)/40

                                               = (5 + 20 + 45 + 28 + 15)/40

                                               = 113/40

                                               = 2.825

Hence, the modal average number of bedrooms is 3, while the mean number of bedrooms is 2.825.

What is a, the initial amount, for the function: f(x) = 300(1.16)*?

Answers

Answer:   300

====================================================

Explanation:

One general template of exponential functions is

f(x) = a*(b)^x

The 'a' is the initial amount, which in this case is a = 300

----------------------

Extra info:

The b is the base of the exponential, which is b = 1.16

The value of b is helpful to determine if you have exponential growth or decay, and how much of either. Because b = 1.16 is greater than 1, it indicates exponential growth. The rate of growth is found by solving 1+r = 1.16 to get r = 0.16, which leads to 16% growth.

Answer:

B. The population for the survey is all people who surf at Breakers Point.

D.Micah's sample will be representative because anyone can surf at Breakers Point.

Step-by-step explanation:

hope it helps

The statements that are true are:

The population for the survey is all people who surf at Breakers Point.

Micah will not get a representative sample.

Options B and C are the correct answer.

What is random sampling?

It is the way of choosing a number of required items from a population given.

Each item has an equal probability of being chosen.

We have,

A.

Micah will obtain a random sample by talking to as many surfers as possible.

This statement is not necessarily true as Micah may not be able to talk to all the surfers at Breakers Point during the time frame mentioned. Additionally,

Randomly selecting surfers would result in a better representation of the population.

B.

The population for the survey is all people who surf at Breakers Point.

This statement is true, as the population of interest is the surfers at Breakers Point.

C.

Micah will not get a representative sample.

This statement is also true, as the survey is conducted only between 8:00 A.M. and 12 P.M, which may not be representative of all surfers at Breakers Point.

Additionally, there may be bias in the sample if Micah only surveys surfers at a certain location or time period.

D.

Micah's sample will be representative because anyone can surf at Breakers Point.

This statement is not necessarily true as not all surfers may surf at the same time or location, or have the same level of experience or preference for surfboard style.

Thus,

The population for the survey is all people who surf at Breakers Point and

Micah will not get representative sample statements are true.
