Answer:

10(3w)=6*5

30w=30

w=1

(not sure if youre meant to just have the equation or find w)

48°F

€1.25

Step-by-step explanation:

The floor area is found by multiplying its length by its width: 6*5=30

The amount of area covered by one tile is found by multiplying its length by its width: 3*w=3w.

Ten tiles are used to cover the floor, so the floor area should be equal to ten times the tile area:

10(3w)=6*5

30w=30

w=1

(not sure if youre meant to just have the equation or find w)

35°F is 13°F lower than the high temp. So, add 13°F to find the high temp.

35+13=48°F

Sixteen bagels cost €20. To find the price of one, we divide the price by the amount bought: 20/16=1.25

f(x)=2x+5 find the interval where the function is increasing

Answers

It is always increasing.

To find increasing and decreasing intervals, we need to find where our first derivative is greater than or less than zero. If our first derivative is positive, our original function is increasing and if g'(x) is negative, g(x) is decreasing.

Answer:

The Expression h(-7) represents the output of h corresponding to the input of -7

Step-by-step explanation:

Answer:

C. The expression h(-7) represents the output of h corresponding to the input of -7.

Step-by-step explanation:

In a function written in function notation, the term h(x) represents the output value while x represents the input value, and h is the name of the function.

So, the expression h(-7) represents the output of h corresponding to the input of -7.

the scale on a map is 1:25000. how many km on the ground is represented by 6cm on the map?

Answers

Given:

The scale on a map is 1:25000.

To find:

How many km on the ground is represented by 6cm on the map?

Solution:

Let x be the km on the ground.

We know that,

1 km = 1000 m

1 m = 100 cm

So,

1 km = 100,000 cm

x km = 100,000x cm

The scale on a map is 1:25000. It means the ratio of map and ground is equal to 1:25000.

[tex]\dfrac{1}{25000}=\dfrac{6}{100,000x}[/tex]

[tex]\dfrac{100,000x}{25000}=6[/tex]

[tex]4x=6[/tex]

[tex]x=\dfrac{6}{4}[/tex]

[tex]x=1.5[/tex]

Therefore, 1.5 km on the ground is represented by 6cm on the map.

Which equation represents a line which is perpendicular to the line y= -5/4x - 4?

A. 4y - 5x = -4

B. 4x - 5y = 15

C. 5x + 4y = -8

D. 4x + 5y = 40

Answers

Answer:

Step-by-step explanation:

4x-5y=15

-5y=-4x+15

y=4/5x+15

4y - 5x = -4 represents the line which is perpendicular to the line y= -5/4x - 4. Option A is correct.

What are perpendicular lines?

Two lines are perpendicular to each other if the product of their slopes is equal to -1.

Given,

y= -5/4x - 4

Slope of this line =m1 = -5/4

Let, slope of required line be m2

Then, (m1)(m2) = -1

(-5/4)m2 = -1

m2 = 4/5

The required line has slope = 4/5

Hence, 4y - 5x = -4 has slope equal to 4/5.
