Ariadne jogs at an average speed of 8 km/h. How far does she travel in 1½ hours?

Answer:

y=30x

Step-by-step explanation:

the slope would be the change in height/time so 150/5 which is 30feet/sec

thus using the form y=mx+b and assuming the balloon started on the ground (0) then y=30x

Answer:

It means like swicthing up thing 09, 18, 04

Step-by-step explanation:

In maths, Distance is described as the quantity of space between two points, and further calculation can be defined as follows:

Given Expression:

[tex]5x + 2 = 30\\\\2(x + 5) = 30\\\\5(x + 2) = 30\\\\2x + 5 = 30[/tex]

To find:

distance=?

Solution:

[tex]5\ days\ \begin{cases} & \text{ if } \text{before school 2 miles} \\ & \text{ if } \text{after school x miles} \end{cases}[/tex]

[tex]\therefore 5(x+2)=30\\\\[/tex]

[tex]\bold{5(x+2)=30}\\\\\bold{5x+10=30}\\\\\bold{5x=30-10}\\\\\bold{5x=20}\\\\[/tex]

[tex]\bold{x=\frac{20}{4} }\\\\\bold{x=4}[/tex]

Therefore, the final answer is "4 miles".

Answer:

[tex]8.9444 = \sqrt{80} [/tex]

Step-by-step explanation:

the distance is equal to the magnitude or modulus of the vector between the coordinates,

to find the distance, find the vector then the magnitude,ie

vector=

[tex] \frac{4}{2} - \frac{ - 4}{ - 2 } = \frac{8}{4} [/tex]

distance=

[tex] | \sqrt{{8}^{2} + {4}^{2} } | = | \sqrt{64 + 16 } | \\ | \sqrt{80 } | = \sqrt{80} = 8.944[/tex]

Answer:

f(5) = 11 , f(0) = 6 , f(-2) = 4

Given expression:

f(x) = x + 6

Find:

f(−2), f(0), f(5)

Computation:

f(x) = x + 6

When x = -2

f(-2) = -2 + 6

f(-2) = 4

When x = 0

f(0) = 0 + 6

f(0) = 6

When x = 5

f(5) = 5 + 6

f(5) = 11

Answer:

The cost for 1 chair is $2.75 and the cost for 1 table is $8.75.

Step-by-step explanation:

Use the elimination method of linear equations to find your answer.

Our equations for this problem are:

3c+5t=52 and 9c+7t=86

Multiply the entire first equation by -3.

-3(3c+5t=52)

Simplify the equation from above:

-9c-15t=-156

Stack the two equations on top of each other and add/subtract:

-9c-15t=-156

9c+7t=86

You should be left with -8t=-70. Simplify this to find the value of t:

t=8.75

Plug the value of t into any of the original equations and solve for c.

3c+5(8.75)=52

Simplify the equation above:

3c+43.75=52

Subtract 43.75 from both sides of the equation:

3c=8.25

Divide both sides by 3 to get your c value:

c=2.75

Answer:

749 miles

Step-by-step explanation:

I divided 107 by 2 and then multiplied that by 14

a person drives 53.5 at that particular speed so they keep driving that amount of miles each hour so it's 749

The distance they will drive, at the same speed, in 14 hours is 749 miles.

Given the following data:

To find how far (distance) will they drive, at the same speed, in 14 hours, we would apply direct proportion:

By using direct proportion:

107 miles = 2 hours

X miles = 14 hours

Cross-multiplying, we have:

[tex]2X = 107 \times 14\\\\2X = 1498\\\\X = \frac{1498}{2}[/tex]

X = 749 miles

Answer:

x = 12°

Step-by-step explanation:

To find the value of x, you have to subtract 65 from 180.

This is because angles on a straight line add upto 180 degrees, and 65 is the supplementary angle of 11x -17.

Hence,

11x - 17 + 65 = 180

11x + 48 = 180

11x = 132

x = 12

Answer:

x:y = 5:6

Step-by-step explanation:

y = x(20/100) + x

y = x (1/5) + x

Factorize X

y = x (1/5 + 1)

y = x (6/5)

5y = 6x

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

ratio x:y = 5:6

The ratio is x:y = 5:6.

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same sort and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is expressed as a: b.

Given:

value of y is 20% more than the value of x

So,

y = x(20/100) + x

y = x (1/5) + x

y = x (1/5 + 1)

y = x (6/5)

5y = 6x

Hence, the ratio is x:y = 5:6.

Answer: f(x) = 2x

g(x) = x + 3

First let us find (fog)(x)

(fog)(x) = f(g(x)

= f(x+3)

= 2(x+3)

= 2x + 6

==> (fog)(x) = 2x + 6

Now let us find (gof)(x):

(gof)(x) = g(f(x)

= g(2x)

= 2x + 3
