Answer:

He has. saved up $110 so far in a savings account. He wants to buy some new clothes since his current wardrobe is getting worn out.

Step-by-step explanation:

a. Eduardo needs $140 more before he can go shopping.

b. 3.5 months will it take Eduardo to save this much money.

c. Eduardo will need to make thoughtful decisions about how he manages his money and balances his spending with his savings goal.

a. Here, we have to find out how much more money Eduardo needs before he can go shopping, we need to calculate the difference between his budget and the amount he has saved:

Remaining money needed = Budget - Saved amount

Remaining money needed = $250 - $110

Remaining money needed = $140

So, Eduardo needs $140 more before he can go shopping.

b. To determine how many months it will take Eduardo to save $140, we can divide the remaining amount by his weekly allowance:

Number of weeks to save $140 = Remaining money needed / Weekly allowance

Number of weeks to save $140 = $140 / $10

Number of weeks to save $140 = 14 weeks

Since there are approximately 4 weeks in a month, we can convert weeks to months:

Number of months = Number of weeks / 4

Number of months = 14 weeks / 4

Number of months = 3.5 months

c. If Eduardo wants to buy the clothes in exactly 3.5 months, he will need to consider some trade-offs to meet his savings goal on time:

Cutting Expenses: Eduardo might need to cut down on unnecessary expenses, like snacks or entertainment, to save more money each week.

Additional Income: He could explore opportunities to earn extra money, such as doing chores or odd jobs for neighbors, to supplement his allowance.

Delayed Purchases: Eduardo could delay spending money on non-essential items until he reaches his savings goal. This might mean postponing purchases that can wait.

Adjusting Budget: Eduardo could reconsider his budget to see if there are any areas where he can reduce spending further to meet his goal faster.

Savings Prioritization: Eduardo could prioritize his savings over other purchases and activities for the next 3.5 months.

Ultimately, Eduardo will need to make thoughtful decisions about how he manages his money and balances his spending with his savings goal.

Answer:

B. y = 9/2x + 36

Step-by-step explanation:

Find the negative reciprocal of the slope of the original line and use the point-slope formula  y − y 1 = m ( x − x 1 )  to find the line perpendicular to  2 x +9 y = − 30 .

y = 9 /2 x + 36                        PERPENDICULAR

Answer:

I believe it's A) "In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality."

Step-by-step explanation:

I say this because that's essentially the first step when solving both an equation and inequality.

(In case you were wondering, the next step would be to divide -3 on both sides, in order to get x by its self.)

Answer:

a = -10

Step by step:

put it in standard form

you get

a+10=0

a = -10

Answer:

a= -12

Step-by-step explanation:

write your line down your paper on the equal sign

than do SADMAP, (backwards PEMDAS) so in this case subtract -7

do that on both sides

-7 cancels out making it positive 7 + -17

add

you should get -10 than bring down a

and you get

A=-10

Answer: This is so because, the circle does not totally cover the area defined by the four squares and this is evident in the workings below.

The area of a square is; Area = l²

Since each circle has area, A = 1 square unit.

Therefore,

Length of Each side of each square = 1 unit

This in turn is the radius of the circle given;

The area of the circle is therefore, Area = πr²

Area = (22/7) × 1²

Area = 3.142 square units

In essence, the area of the circle is less than 4 square units.

Answer:

Alicia

Step-by-step explanation:

First, convert the mixed fractions into improper fractions

Alicia

Distance: 5 1/2 = 11/2 = 5.5 miles

Time: 1 2/5 = 7/5 = 1.4 hours

Carlos

Distance: 8 1/8 = 65/8 = 8.125 miles

Time: 2 1/2 = 5/2 = 2.5 hours

Henry

Distance: 3 2/3 = 11/3 = 3.6 reoccuring miles

Time: 1 1/10 = 11/10 = 1.1 hours

Zoe

Distance: 4 2/3 = 14/3 = 4.6 reoccuring miles

Time: 1 3/10 = 13/10 = 1.3 hours

After that, divide the distance by the time

Alicia = 5.5 / 1.4 = 3.93 ( 3 s.f )

Carlos = 8.125 / 2.5 = 3.25

Henry = 3.6 re / 1.1 = 3.3 reoccuring

Zoe = 4.6 / 1.3 = 3.54 ( 3 s.f )

Looking at these answers, we determine which rate is the greatest

Alicia = 3.93

Carlos = 3.25

Henry = 3.3 re

Zoe = 3.54

Alicia hiked the highest rate.

Step-by-step explanation:

2 + (1^2 - 1 ) = 2

2 +( 2^2 - 1 ) = 5

5 + ( 3^2 - 1) = 28

28 + (5^2 - 1) = 52

Thus the next number would be 52

Hope this helps :D

Answer:

  9.1 cm

Step-by-step explanation:

The law of cosines can be used to find the missing side.

  l² = m² +n² -2mn·cos(L)

  l² = 8² +2.8² -2(8)(2.8)cos(103°) ≈ 81.9178

  l ≈ √81.9178 ≈ 9.0508

The length of l to the nearest tenth centimeter is 9.1 cm.

Answer:

isosceles, acute

Step-by-step explanation:

isosceles because there are two equal sides and acute because none of the angles is greater than 90 degrees

The solution of the system of equations  2x+3y=9 and y=x+8 is x = -3 and y = 5.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the two equations are 2x + 3y = 9 and y = x + 8. The value of x and y is calculated as:-

2x + 3y = 9

y = x + 8

Solve the equations as;-

2x + 3y = 9

-2x + 2y  = +16

___________

      5y = 25

        y = 5

y = x + 8

x = 8 - 5

x = 3

Therefore, the solution of the system of equations  2x+3y=9 and y=x+8 is x = -3 and y = 5.

Answer:

y=-x-3

I attached a file so you can plot the points on your own.

Answer:

Step-by-step explanation: First we need to figure out the slope. There are two ways:

First you need to find the slope with Δy/Δx. This will plug in as

-7 - (-6)/ 4 - 3. This will simplify to -1/1, then -1. So m = -1

Now we have the equation y = -1x + b. We need to find b.

In order to do that, we need to plug in one of the points. I'm using (3,-6) but you can use whatever point. Once we plug it in, we have -6 = -(3) + b. Solve for b and you get -3. So the final equation is y = -x - 3.

Like the slope intercept form, we need to find the slope, in which case is -1. Next, we can use one of the ordered pairs again to plug it into the equation

y -  [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex]), where [tex]y_{1}[/tex] is the y of the pair and [tex]x_{1}[/tex] is the x of the pair. You can use the other points too. The final equation once you plug it in is y -(-6) = -(x-3) or y + 7 = -(x - 4).
