Answer:

x intercept is 8, y intercept is 10

Step-by-step explanation:

x intercept is the x value for which the graph crosses the x-axis. Similar for y.

5x + 4y = 40 describes a straight line, so we should have no problem with finding those values

Let's find an x for which y = 0

5x + 4y = 40

substitute y=0

5x = 40

x = 8

Let's find a y for which x = 0

5x + 4y = 40

substitute x=0

4y = 40

y = 10

Answer:

True.

Step-by-step explanation:

It is given that, a regular hexagon is dilated by a scale factor of 0.4 to make image.

It means, the perimeter of image is 0.4 times the perimeter of the original hexagon.

For example,

Let's take the rectangle with length of 12 and width of 4, it's perimeter is 12+12+4+4 =32

Let's find image using scale factor 0.4, we get

length =0.4(12)= 4.8

width =0.4(4)=1.6

So, perimeter of image = 4.8+4.8+1.6+1.6=12.8

If we compare the perimeters

0.4(32)=12.8.

So, it is true.

Answer:

y - 4 = x

Step-by-step explanation:

4 less than y is y minus four, so therefore y - 4 = x

Answer: 16

Step-by-step explanation:

Assume that this number is x:

When seven more than this number is doubled, the result is 46. In formula form that would be:

2 * (7 + n) = 46

Solving this formula:

2 * ( 7 + n) = 46

7 + n = 46/2

n = 46/2 - 7

n = 16

Answer:

An exponent is a number or letter written above and to the right of a mathematical expression called the base. It indicates that the base is to be raised to a certain power. x is the base and n is the exponent or power

Example:

[tex]5^{2}[/tex] = 25

not 5x2

5x5

the numeber times the number itself by how many times the exponet says.

***i hope i was clear! ^^

Answer:

An exponent refers to the number of times a number is multiplied by itself. For example 2 to the 3rd.It means 2*2*2=8.

2 to the third is not the same as 2*3=6

if you want to know what I mean by 2 to the 3rd please take at the picture above

Answer:

R = 10 cm

Step-by-step explanation:

The area of a spherical shape is given by :

[tex]A=4\pi r^2[/tex]

Where

r is the radius of the sphere

ATQ,

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large bubble.

The radius of each small bubble is 5 cm

Using the given condition,

[tex]4\pi R^2=4\times (4\pi r^2)\\\\R^2=4r^2\\\\R=\sqrt{4r^2} \\\\R=2r\\\\R=2\times 5\\\\R=10\ cm[/tex]

So, the radius of the large bubble is equal to 10 cm.

Answer:

20cm

Step-by-step explanation:

5cm+5cm+5cm+5cm=20cm

Answer:

Answer = C.31.25

Step-by-step explanation:

SO there are 4 years and every year the price gets 50% of so we take it as 100/2 = 50% so we have to divide 500 by 2 four times that is -

1. 500/2 ( 50% of 500) = 250

2. 250/2 (50% of 250) = 125

3. 125/2 (50% of 125) = 62.50

4. 62.50/2 (50% of 62.50) = 32.25

so we divided 500 4 times to get the answer as 32.25$

okay first lets look at the question once again $24? 1. Taxi Fares are normally distributed with mean fare $22.27 and a standard deviation of $2.20.

A) What is the probability of a single Taxi fare being over $24? 0.2158

What is the probability that the average of a random sample of 10 taxi fares being over 'Sd=22 0068

B) Which should have a greater probability of being between $12 and $24 - the mean of 10 randomly selected taxi fares or the amount of a single randomly selected taxi fare? Why?​

So for A. its i dont know

and for B. its i dont know either

Answer:

how many floors the elevator goes down per unit of time

Step-by-step explanation:

not sure what the unit of time is but its seconds or minutes im pretty sure it doesnt say

Answer:

The elevator started at floor 7

Step-by-step explanation:

The y-intercept is when x is 0

In this situation x represents time, so when no time has passes yet y is at 7

This means that the elevator was at floor before any time passed (before it started moving)

hope this helps, lmk if it doesnt :)

Answer:

Area = 615.75 [tex]m^{2}[/tex]

Step-by-step explanation:

A = π [tex]r^{2}[/tex]

A = 3.14 x [tex]14^{2}[/tex]

A = 615.75 [tex]m^{2}[/tex]

Answer:

b

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{KL}{EF}[/tex] = [tex]\frac{JK}{DE}[/tex] , substitute values

[tex]\frac{6x+3}{x+11}[/tex] = [tex]\frac{25}{10}[/tex] ( cross- multiply )

10(6x + 3) = 25(x + 11) ← distribute parenthesis on both sides

60x + 30 = 25x + 275 ( subtract 25x from both sides )

35x + 30 = 275 ( subtract 30 from both sides )

35x = 245 ( divide both sides by 35 )

x = 7

Then

KL = 6x + 3 = 6(7) + 3 = 42 + 3 = 45 → b

Answer:

A is correct. :)

Answer:

y= 500+7x

Step-by-step explanation:

Given data

Total amount for the rent=  $500

Cost of food per night= $10

Family charges per night=$60

Let the number of nights be x

and let the total charges be y

Hence, the expression for the situation is given as

y=500+10x+60x

y= 500+7x

Answer:

2/3

Step-by-step explanation:

Probability =

= No. of faces having less than 5 spots / Total no. of faces

= 4/6

=2/3

The probability of a face with less than 5 spots turning up when it tosses a die which has 6 total outcomes is 2/3 or 0.667.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

The probability of a face with less than 5 spots turning up when a die is tossed has to be find out.

Here, in this die, it is known that,

Thus, the probability of this event is,

[tex]P=\dfrac{4}{6}\\P=\dfrac{2}{3}\\P=0.667[/tex]

Thus, the probability of a face with less than 5 spots turning up when it tosses a die which has 6 total outcomes is 2/3 or 0.667.

Answer:

is it written like this?

if so then the coefficient of y is 1

Answer:

¼

Step-by-step explanation:

A coefficient is the number that comes before a variable, including its sign (plus/minus). Thus, the coefficient of y is the number that comes before the variable y.

[tex] \frac{y}{4} [/tex] can also be written as [tex] \frac{1}{4} y[/tex]. Since the sign before ¼ is a plus sign, the coefficient of y can simply be written as ¼.
