The weight of Jack is 30kg 500g. The weight of Dereck is 28kg 700g. What is their total weight? Also, find the difference of their weight?

Answers

Answer 1

Answer:

Below.

Step-by-step explanation:

30 kg 500g + 28kg 700g

= 58kg + 1200g

= 59kg 200g.

Difference

= 30 kg 500g - 28kg 700g

= 2kg + 500 - 700

= 2kg - 200g

= 1kg 800g.

Find the intersection point for the following linear functions.

f(x) = 2x + 3
g(x) = -4x − 27

A.
(5,13)
B.
(5,-7)
C.
(-5,-10)
D.
(-5,-7)

Answers

Answer:

(-5,-7)

Step-by-step explanation:

To find points of intersection, first set the two equations equal and then solve for x. Then substitute that x back into either equation for the complete point of intersection.

2x + 3 = -4x - 27

6x = -30

x = -5

2(-5)+3 = -10 + 3 = -7    (substituting our solution into f(x) here)

A handful of coins has the value of 1 dollar and 79 cents. There are three times as many dimes as quarters, and five more pennies than dimes. If there are only three types of coins, how many coins of each type are there?

Answers

Answer: There are 3 quarters , 9 dimes and 14 pennies.

Step-by-step explanation:

Let x= Number of quarters

Then, Number of dimes = 3x

Number of pennies = 3x+5

1 quarter = $ 0.25

1 dime = $0.10

1 penny = $ 0.01

So, Total amount = 0.25x+ 0.10(3x) + 0.01(3x+5)

= 0.25x+0.30x+ 0.03x+0.05

= 0.58x+0.05

Since Total amount = 1 dollar and 79 cents = $ 1.79  [1 cent = $ 0.01]

So,

[tex]0.58x+0.05=1.79\\\\\Rightarrow\ 0.58x= 1.74\\\\\Rightarrow x=\dfrac{1.74}{0.58}\\\\\Rightarrow x=3[/tex]

Thus, there are 3 quarters , 9 dimes , 14 pennies.

Answer:

Step-by-step explanation:

there are 3 quarters , 9 dimes , 14 pennies.

consider the steps for determining the quotient of 12/x-4 / 4/x-4

Answers

Answer:

Quotient = 3

Step-by-step explanation:

We need to solve the given expression :

[tex]\dfrac{\dfrac{12}{x-4}}{\dfrac{4}{x-4}}[/tex]

It can be done as follows :

As, [tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]

So,

[tex]\dfrac{\dfrac{12}{x-4}}{\dfrac{4}{x-4}}=\dfrac{12}{x-4}\times \dfrac{x-4}{4}\\\\=\dfrac{12}{4}\\\\=3[/tex]

Hence, the required quotient is 3.

find values of x and y??

Answers

Answer:

x = 80y = 122

Step-by-step explanation:

The angles marked with x-expressions are complementary, so ...

  (3/4x -2) + (2/5x) = 90

  x(3/4+2/5) = 92 . . . . . . . add 2

  x(23/20) = 92 . . . . . . . . combine the fractions

  x = 92(20/23) . . . . . . . . multiply by 20/23

  x = 80

__

The angle marked y° is a vertical angle with the angle that is the sum of 90° and (2/5x)°. So, the value of y is ...

  y = 90 + 2/5(x) = 90 +2/5(80) = 90 +32

  y = 122

The cost for 25 square yards of carpet is $650 including delivery and installation. The cost for 40 square yards of installed carpet is $950. Write an equation in slope-intercept form (y = mx + b) for the cost of the installed carpet

Answers

Answer:

The equation is;

y = 20x + 150

Step-by-step explanation:

Firstly, let us identify the coordinates

(area, cost of area)

We start by getting the points;

(25,650) and (40,950)

The slope will be;

m = (y2-y2)/(x2-x1)

m = (950-650)/(40-25)

m = 300/15 = 20

So the partial equation is;

y = 20x + c

To get the value of c which is the y-intercept, we make use of any of the two points

650 = 20(25) + c

650 = 500 + c

c = 650-500

c = 150

Harold Crispen worked Monday, Tuesday, and Thursday from 9:00 A.M. to 4:30 P.M. with a half hour lunch each day. What were his total hours worked? 21 22.5 30 28​

Answers

Answer:

His total hours he worked is;

21

Step-by-step explanation:

The of hours between 9:00 A.M.  and 4:30 P.M. are;

[tex]\begin{array}{ccc}From \ 9:00 \, A.M. & to \ 10:00\, A.M. & = 1 \, Hour\\From \ 10:00 \, A.M. & to \ 11:00\, A.M. & = 1 \, Hour\\From \ 11:00 \, A.M. & to \ 12:00 \, P.M. & = 1 \, Hour\\From \ 12:00 \, P.M. & to \ 1:00 \, P.M. & = 1 \,Hour\\From \ 1:00 \, P.M. & to \ 2:00 \, P.M. & = 1 \,Hour\\From \ 2:00 \, P.M. & to \ 3:00 \, P.M. & = 1 \,Hour\\From \ 3:00 \, P.M. & to \ 4:00 \, P.M. & = 1 \,Hour\\From \ 4:00 \, P.M. & to \ 4:30 \, P.M. & = 0.5 \, Hour \end{array}[/tex]

Sum of the hours Harold Crispen spends at the workplace on a workday = (1 + 1 + 1 + 1 + 1 + 1 + 1 + 0.5) hours = 7.5 hours

The time Harold Crispen take for launch each workday = 0.5 hour

The number of hours Harold Crispen spend working each day = (7.5 - 0.5) hour

The number of hours Harold Crispen spend working each day = 7.0 hours/day

The number of days he worked = Monday + Tuesday + Thursday = 3 days

The total hours he worked = (The number of hours he works each day) × (The number of days he worked)

His total hours he worked = 7.0 hours/day × 3 days = 21.0 hours.

Answers

Answer:

down 2, right 1

Step-by-step explanation:

Here, we want to know what -2 means for the slope

The following conventions are necessary to be known;

down is negative

left is negative

up is positive

right is positive

Thus;

Since the slope is actually vertical change/ horizontal;

The 2 value must be in respect to the y-axis

Hence;

up 2 right 1 is positive

down 2 left 1 is positive since both are negatives

The correct answer is thus;

down 2, right 1
