the larger of two numbers is 10 less than twice the smaller number. If the sum of the two numbers is 38, find the two numbers. Show how you got your answer?

Answers

Answer 1
x = larger number, y = smaller number

x + y = 38...because the sum of the numbers is 38
x = 2y - 10....larger one is 10 less then twice the smaller

now we will sub in 2y - 10 for x back into the first equation
x + y = 38
2y - 10 + y = 38
3y - 10 = 38...add 10 to both sides
3y = 38 + 10
3y = 48 ...divide both sides by 3
y = 48/3
y = 16

now sub 16 in for y back into either of the original equations and find x
x = 2y - 10
x = 2(16) - 10
x = 32 - 10
x = 22

so ur numbers are 16 and 22
Answer 2

The larger number will be 22 and the smaller number will be 16.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say the larger number is L and the smaller number is s

Given the larger of the two numbers is 10 less than twice the smaller number

So,

L = 2s - 10

And

The Sum of the two numbers is 38

So,

L + s = 38

By substitution

38 - s = 2s - 10

s = 16

By again substitution

L = 2(16) - 10

L = 22

Hence "The larger number will be 22 and the smaller number will be 16".

There are 111 guest attending a party there are 15 servers each server has the same number of guest to serve Jess will serve any extra guest how many guest will Jess be serving? Please help me

Answers

11 divided by 7 is the biggest factor.
So, each sever served 7 guests. Jess served 7+6 so 13.

Answer:  The required number of guests served by Jess is 13.

Step-by-step explanation:  Given that there are 111 guest attending a party there are 15 servers each server has the same number of guest to serve.

If Jess will serve any extra guest, then we are to find he number of guests served by Jess.

By division algorithm, we can write

[tex]111=7\times15+6\\\\\Rightarrow 111=7\times14+(7+6).[/tex]

So, 14 servers will serve 7 guests each and Jess will serve 7 guests along with extra 6 guests.

Therefore, the total number of guests served by Jess is given by

Shawn wants to model the number 13,450 using base ten blocks how many large cubes flats and longs does he need model the number

Answers

1 small cube = 1 small cube
   
10 small cubes = 1 long
   
10 longs (or 100 small cubes) = 1 flat
   
100 flats (or 1000 small cubes) = 1 large cube
           
13,450 needs to be divided into groups (by number). Separate by thousands, hundreds, and tens. There are 13 thousands in 13,000. That leaves 450 remaining. 450 is 4 hundreds and 5 tens. 1 large cube is 1000 small cubes. 1000 * 13 = 13,000. You need 13 cubes, with a total of 450 remaining. 100 small cubes is 1 flat. 100 * 4 = 400. You need 4 flats, with 50 remaining. 10 small cubes are 1 long. 10 * 5 = 50. You need 13 cubes, 4 flats, and 5 longs.

A crane cable can support a maximum load of 22,000 kg. If a bucket has a mass of 5,000 kg and gravel has a mass of 1,500 kg for every cubic meter, how many cubic meters of gravel can safely lifted by the crane?

Answers

Final answer:

The crane can safely lift approximately 11.33 cubic meters of gravel, taking into account the maximum load the cable can support and the mass of the bucket and gravel.

Explanation:

We need to calculate the maximum volume of gravel a crane cable can lift, given the maximum load it can support. The crane's cable can support a maximum load of 22,000 kg. Since the bucket that carries the gravel has a mass of 5,000 kg, we subtract this mass from the maximum load the cable can support to find the maximum mass of gravel that can be lifted:

22,000 kg (max load) - 5,000 kg (bucket mass) = 17,000 kg (max gravel mass)

Given that 1 cubic meter of gravel has a mass of 1,500 kg, we can calculate the volume of gravel that can be safely lifted by the crane by dividing the maximum gravel mass by the mass of gravel per cubic meter:

17,000 kg (max gravel mass) ÷ 1,500 kg/m³ (gravel density) = 11.33 m³

Therefore, the crane can safely lift approximately 11.33 cubic meters of gravel.

the axis of symmetry is the coordinate of x, i.e. x=2

Answer:

axis of symmetry at x=2

Step-by-step explanation:

[tex]y - 4x = 7 - x^2[/tex]

LEts solve for y

Add 4x on both sides

[tex]y=- x^2+4x+7[/tex]

To find axis of symmetry we use formula

How do I solve this question?

Answers

Before attempting to solve this question, we must first know three things.

1. A straight line has a measure of 180 degrees.

2. When two angles add up to 180 degrees, those angles are called supplementary.

3. The interior angles of a triangle add up to 180 degrees.

We can see ∠ECT = 180 degrees.

∠DCT is supplementary to ∠DCE.

∠DCT = 140 degreees
∠DCE = x degrees

x + 140 = 180

Solve for x.

x + 140 = 180
x = 40 <-- Subtract 140 from each side

∠DCE = 40 degrees

We know the two interior angles of ΔDEC.

45 + 40 + x = 180

Solve for x.

45 + 40 + x = 180
85 + x = 180 <-- Combine like terms
x = 95

So, the missing angle is equal to 95 degrees.

A one-minute advertisement on a local television station during prime time (8- 10 p.m. on weeknights) costs the advertiser $12,800. To the nearest cent, how much does the advertisement cost per second? Show your work using dimensional analysis and Giant Ones.

Answers

Cost = $12,800
Time = 2 hours, 8 - 10 pm

Cost per hour = ($12800)/(2) = $6400 per hour

There are 60*660 = 3600 seconds per hour.
Therefore the cost per second is
($6400)/(3600 s) = $1.7778 per second  = $1.78 per second (nearest cent)

Answer: $1.78 (nearest cent)
Final answer:

The cost of the advertisement per second is $213.33 to the nearest cent.

Explanation:

To find the cost per second of the advertisement, we need to convert the cost from dollars per minute to dollars per second. We can use dimensional analysis to do this.

First, we know that there are 60 seconds in one minute. So, we can set up a conversion factor to convert from minutes to seconds:
1 minute = 60 seconds

Next, we set up a ratio using the given cost per minute and the conversion factor:
$12,800/1 minute * 1 minute/60 seconds = $213.33/second

Therefore, the cost of the advertisement per second is $213.33 to the nearest cent.

Your teacher divides your class into two groups and then randomly chooses a leader for each group the probability that you are chosen to be a leader is 1÷12 the probability that both you and your best friend are choosing is 1÷132 is your best friend in your group explain

Answers

Answer:

1 DIVIDED BY 12 IS 1 SO SAME THING WITH 1 DIVIDED 132 IS 132 SO ADD THEM AND YOU SHOULD GET YOUR ANSWER PS i dont know the answer

Step-by-step explanation:

No, my best friend is not in my group.

Let's break down the probabilities to determine if your best friend is in your group. The probability that you are chosen as a leader is [tex]\frac{1}{12}[/tex]. Let’s denote your best friend by BF. Given that the probability that both you and best friend are chosen as leaders is [tex]\frac{1}{132}[/tex], we need to check if BF is in your group.If your best friend is in your group, then there is only one leader to be chosen from this group. Hence, the probability that you and your best friend are chosen from the same group would be calculated by selecting the group leader and then the remaining leader from the other group.In this scenario, the probability of you and your best friend being chosen as leaders would typically depend on the group size and configuration.Since the probability of you both being chosen is [tex]\frac{1}{132}[/tex], this indicates that you are more likely not in the same group. If BF were in the same group, the probability would be calculated based on how likely both members are to be from the same group, considering the overall class size and number of groups.Thus, given the probability details, we can conclude that your best friend is not in the same group as you.
