Answer 1

Answer:

EH = HG

EH = HG

2x + 24 = 5x - 30

x = 18

EH = 60

HG = 60

Step-by-step explanation:

what is question 4 ?

you mean the 4th point in this question, or is the whole thing question 4 ?

in any case, what they want to see here is

EH = HG (because FH is the median of the triangle, so it cuts the baseline in half).

therefore we get

2x + 24 = 5x - 30

54 = 3x

x = 18

EH = 2×18 + 24 = 36 + 24 = 60

HG = 5×18 - 30 = 90 - 30 = 60

as expected - they are equal.

Answers

Answer:

c

Step-by-step explanation:

To find the midpoint the formulas

x=x1+x2/2 and y=y1+y2/2 are used

in this case x1 is 5,x2 is 5,y1 is 4 and y2 is -3

therefore

x=5+5/2.

=10/2

=5

y=4+(-3)/2

=1/2

The midpoint of a line segment divides the line into equal segments

The midpoint of the line segment is (5,1/2)

The endpoints of the line is given as:

(5,4) and (5,-3)

The midpoint of the line is calculated as:

(x,y) = 0.5(x1 + x2, y1 + y2)

So, we have:

(x,y) = 0.5(5 + 5, 4 - 3)

Evaluate the sum and difference

(x,y) = 0.5(10, 1)

Evaluate the product

(x,y) = (5, 1/2)

Hence, the midpoint of the line segment is (5,1/2)

Jack plotted the graph below to show the relationship between the temperature of his city and the number of ice cream cones he sold daily: Main title on graph is Ice Cream Cone Sale. Graph shows 0 to 30 on x axis at increments of 5 and 0 to 60 on y axis at increments of 10. The label on the x axis is Temperature in degree C, and the label on the y axis is Number of Ice Cream Cones Sold. Dots are made at the ordered pairs 0, 5 and 5, 15 and 7.5, 15 and 10, 24 and 10, 28 and 12, 32 and 12.5, 25 and 12.5, 30 and 15, 35 and 15, 40 and 17.5, 35 and 20, 45 and 22.5, 36 and 23, 46 and 25, 55 and 27.5, 60. Part A: In your own words, describe the relationship between the temperature of the city and the number of ice cream cones sold. (5 points) Part B: Describe how you can make the line of best fit. Write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate slope and y-intercept. (5 points)

Answers

Answer:

(a) The amount of ice cream increase as temperature increases

(b)

[tex]y = 2x + 5[/tex] --- equation

[tex]y = 5[/tex] --- y intercept

[tex]m = 2[/tex] --- slope

Step-by-step explanation:

Given

See attachment for graph

Solving (a): The relationship between the variables

From the attached graph, the dots on the graph increases towards up-right direction. This implies that there is a positive correlation between the variables.

In other words;

The amount of ice cream increase as temperature increases

Solving (b): The line of best fit

First, we draw a line through the points (the line should have almost equal points on both sides; see attachment 2).

From (2), we select any 2 points on the line:

[tex](x_1,y_1) = (15,35)[/tex]

[tex](x_2,y_2) = (0,5)[/tex]

The slope (m) is:

[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{5-35}{0-15}[/tex]

[tex]m = \frac{-30}{-15}[/tex]

[tex]m = 2[/tex]

So, the line of best fit is:

[tex]y = m(x - x_1) + y_1[/tex]

Substitute known values:

[tex]y = 2(x - 0) + 5[/tex]

[tex]y = 2(x) + 5[/tex]

[tex]y = 2x + 5[/tex]

The y-intercept is when [tex]x=0[/tex]

So, we have:

[tex]y = 2*0 + 5[/tex]

[tex]y = 0 + 5[/tex]

[tex]y = 5[/tex]

Step-by-step explanation:

Write the equation of the line that passes through the points (8, –1) and (2, –5) in standard form, given that the point-slope form is y + 1 = (x – 8).

Answers

Answer:

A linear equation in the standard form is written as:

y = a*x +b

where a is the slope and b is the y-intercept.

If we know that the line passes through the points (a, b) and (c, d), then the slope can be written as:

a = (d - b)/(c - a)

So we know that our line passes through the points (8, -1) and (2, -5)

then the slope will be:

a = (-5 - (-1) )/(2 - 8) = (-4/-6)  = 2/3

Then our line is something like:

y = (2/3)*x + b

to find the value of b, we can use the fact that we know that our line passes through the point (2, -5)

this means that when x = 2, we must have y = -5

replacing these values in the equation we get:

-5 = (2/3)*2 + b

-5 = 4/3 + b

-5 - 4/3 = b

-15/3 - 4/3 = b

-19/3 = b

then the equation is:

y = (2/3)*x - 19/3

(in the question you wrote the point-slope form, but you can see that it does not work for the second point, so there may be a mistake there, as the slope is missing)

The actual equation in the point-slope form is:

y + 1 = (2/3)*(x - 8)

Answer:

The answer is 2x + -3y = 19

Step-by-step explanation:

just try to expand the answer given for example when you look at no.1, 2x•x=2x^2 so look for the equation where there is a 2x^2 in it.

for finding the solution, for example when you look at no.1 again, you have 2x=0 so x=0/2=0 and you also have x+3=0 so x=-3

this applies to all the pther no.

A and B are partner in a business .A contribution RS 20000 and B rs 30000 a however acts as a manager the understanding being that of the profit should get 25% for his service as manager the remaining divided in the ratio of their contribution .If B ges Rs 1350 Ashish share what would A get

Answers

Answer:

Rs 1,650

Step-by-step explanation:

The given contribution are;

A contributes Rs 20,000, and B contributes Rs 30,000

The percentage of the profit A receives as manager = 25%

The amount of the profit divided in the ratio of their contribution = The remaining profit (75%)

The amount B gets = Rs1,350

The amount A gets = required

The ratio of their contribution at which the remaining profit is shared = 20,000:30,000 = 2:3

Where, out of 5 parts of 75% of the profits, B gets 3, while A gets 2

Let P represent the profit, we have;

B's share = 3/5× 0.75 × P = 1,350

∴ P = (5 × 1,350/3)/0.75 = 3,000

A gets 25% of the profits and 2/5 of the 75% remaining profit

∴ The amount A gets = 0.25×3000 + (2/5)×0.75×3000 = 1,650

Or simply put;

A gets the remainder of the profit which is Rs 3,000 - Rs 1,350 = Rs 1,650

find the LCM and hcf of 72 and 162 , leaving the LCM in prime factors

Answers

Answers:  LCM = 2^3*3^4HCF = 18

=========================================================

Explanation:

Find the prime factorization of 72 and 162

72 = 8*9 = 2^3*3^2162 = 2*81 = 2*9^2 = 2*(3^2)^2 = 2*3^4

Here's a simplified version of each

72 = 2^3*3^2162 = 2*3^4

We have these unique primes: 2, 3

Circle the terms that have the largest exponents for each of those unique primes. So you'll circle 2^3 and 3^4. Those items circled will multiply together to get the LCM.

This means 2^3*3^4 is the LCM (lowest common multiple).

2^3*3^4 turns into 648, but your teacher wants you to keep the LCM in prime factor form.

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

Now onto the HCF (highest common factor; aka GCF).

Looking at

72 = 2^3*3^2162 = 2*3^4

We again see '2's and '3's as the unique primes. Both have at 1 copy of '2' between them. They also both have 3^2 between them. It might help to think of 3^4 as 3^2*3^2.

Those common factors you circled are then multiplied.

Overall, the HCF is 2*3^2 = 2*9 = 18

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

Side note: The HCF is useful to help reduce fractions, while the LCM is useful to help find the LCD (lowest common denominator) when adding or subtracting fractions of different denominators. There are other applications of each of these.

Answer:

LCM= 648

HCF= 18

what is the significant figures for 0.045325​

Answers

Answer:

There are 5 significant digits in 0.045325 and they are 4, 5, 3, 2, and 5.

Step-by-step explanation:

Significant digits rules:

All non-zero numbers count as significant digitsLeading zeroes (zeroes in front of any non-zero numbers) are never significant digitsZeroes in-between non-zero numbers count as a significant digitsTrailing zeroes (zeroes after all non-zero numbers) count only if there is a decimal

In 0.045325, the two zeroes are leading zeroes and therefore do not count. The rest of the digits, (4, 5, 3, 2, and 5) are all non-zero and therefore count. Thus, there are 5 significant digits in 0.045325.

i reallyyy need help ! a p e x

Answers

Answer:

D

Step-by-step explanation:

Because the closed dot is connected to the one less than 1, we know that one of the equation is less than or equal to 1. So this eliminates A.

B makes no sense because it shows two equations for when x < 1. So this one can be ruled out immediately.

We also notice the shape of the functions, the one on the bottom looks like a cube, you can make out the beginning of the chair shape.  So the one that is less than or equal to 1 is the cubic function. Which eliminates C.

This leaves D and you can plug in values of x and y to confirm this is correct.

Answer:

Step-by-step explanation: First you look at the left side of the graph. You can tell by the shape that it is an x^3 function. also the filled in circle means inclusive. so we know that when x <= (whatever number). It is impossible to tell for sure with this graph if it is on 1. for the first part. the only answer that has less then or equal to is the last one, D. So the answer is D. You can look at the right side that it is open circle. So we know it is >. So we can see the bottom part of D has that as well

Mike, a Salvation Army bell ringer, has 20% as many quarters as nickels in his cup. If Mike has $6.00 in quarters and nickels, how many nickels does he have?

Answers

5.8 Nickels

Step-by-step explanation:

Let x rep no of Nickels in Mike's cup

Then x - 0.2 = Number of quarters in Mike's cup

0.2x = Amount of money that mike has from the nickels

1 ( x - 0.2) = Amount of money that Mike has from the quarter

Then,

0.2x + 1 (x - 0.2) = 6

Expand the bracket

0.2x + x - 0.2x = 6

x = 6

Recall

x - 0.2 = 0

6 - 0.2 = 5.8

Therefore, Mike has 5.8 nickels for the quarter
