Answer:

y=0.25x-1

Step-by-step explanation:

y=mx+b

slope = 0.25

y = 0.25x+b

the y intercept = -1

y = 0.25x+-1

y = 0.25x-1

Step-by-step explanation:

The height of logo is 7.6 cm.

An ellipse is a closed curve, the intersection of a right circular cone and a plane that is not parallel to the base, the axis, or an element of the cone.

Given:

x²/64 + y²/14.44=1

We know

x²/a² + y²/b² =1

On comparing

a²=64

and, b²=14.44

Also, a=8 and b= 3.8

So, length of logo will be = 2h

=2* 3.8

=7.6 cm

Answer:

tall candles = 39

Short candles = 52

Step-by-step explanation:

let tall candles be x

and short candles be y

No. Of candles sold = x + y =91

Money made from candles will be equal to = 8x + 5y = $572

These both are simultaneous linear equations.

x + y =91 ( multiply by 5)

5x + 5y = 455

8x + 5y = $572

Subtract them:

-3x = -117

x = -117/3

x = 39

put value of x in

x + y = 91

39 + y = 91

y = 91 - 39

y = 52

x shows tall candles so they are 39

y shows short candles so they are 52

Answer:

I wanna say in the year of 2018.

Step-by-step explanation:

In 2018 the population will reach 40 million.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let us consider x years later it would reach 40 million.

So, 39.1 + 0.35 x = 40

0.35x= 40- 39.1

0.35x= 0.9

x= 2.57

x= 3 years

Hence, In 2018 the population will reach 40 million.

Answer:

f(x)=15 when: 0<x(less than or equal to)3

f(x)=22 when: 3<x<7

f(x)=30 when: 7(is less than or equal to)x

Part B- Evaluate the function for f(2): 15

Step-by-step explanation:

Algebra Nation; Section 8 topic 6

The domain of each function is the set of all possible values of t for which the function is defined. In this case, the domain of each function is:

For f(t) = 15: 0 < t ≤ 3

For f(t) = 22: 3 < t ≤ 7

For f(t) = 30: t > 7

The admission prices at the amusement park can be represented as functions of the amount of time a customer spends at the park. Let's denote the amount of time by t (in hours). Then we can define the following functions:

For t ≤ 3: f(t) = 15

For 3 < t ≤ 7: f(t) = 22

For t > 7: f(t) = 30

The domain of each function is the set of all possible values of t for which the function is defined. In this case, the domain of each function is:

For f(t) = 15: 0 < t ≤ 3

For f(t) = 22: 3 < t ≤ 7

For f(t) = 30: t > 7

Note that the domain for each function reflects the fact that customers can only be charged according to the specified rates for the corresponding time intervals.

Additionally, since the amusement park is open for 15 hours a day, 7 days a week, we can say that the total operating time is 15 x 7 = 105 hours per week.

Answer:

100%

Step-by-step explanation:

Assuming Zoe throws a dart at a target 9 times. The relative frequency of Zoe hitting the bullseye is 100%.

Relative frequency=Number of times a dart is throwed/Number of times the bullseye is hits×100

Where:

Number of times a dart is throwed=9 times

Number of times the bullseye is hits=9 times

Let plug in the formula

Relative frequency=9/9×100

Relative frequency=100%

Inconclusion the relative frequency of Zoe hitting the bullseye is 100%.

Step-by-step explanation:

Answer:

Step-by-step explanation:

The total sum of angles around a point is 360 degrees.

Step-by-step explanation:

Formula for simple interest:

[tex]a = p(1 + rt)[/tex]

where

a = final amount

p = principal amount

r = interest rate per annum

t = time in years

Now, we are finding a, the final amount, and given,

p = $650

r = 5.5% (5.5/100)

t = 4 years

[tex]a = 650(1 + (\frac{5.5}{100} )(4)) \\ = 650(1 + (0.055)(4)) \\ = 650(1 + 0.22) \\ = 650(1.22) \\ = 793 \: dollars[/tex]

Answer:

C.$793

Step-by-step explanation:

were looking to 5.5% of 650 but in order to do that first we need to find 1%, we can do that by dividing by 100

650=100%

/100  /100

6.5=1%

now we can multiply by 5.5 to get 5.5%

6.5 = 1%

x5.5 x5.5

35.75=5.5%

now we are looking to find how much money is in the account total after 4 years

so the equation is

(35.75x4)+650

143+650

$793 in total
