Answer:
1,500 Kg
Step-by-step explanation:
Formual for froce is given by
force = mass * acceleration
Force exerted by 1 woman = 425 N
no. of women exerting force = 3
Force exerted by 3 woman = 425 * 3 N = 1275 N
Acceleration produced by 1275 N force = 0.85 m/s^2
Using formula force = mass * acceleration
1275 = mass * 0.85 m/s^2
=> mass = 1275/ 0.85 m/s^2 = 1,500 Kg
Thus, mass of car is 1,500 Kg.

Jocelyn sells necklaces for $8 each. It costs her $20 for
materials to make the necklaces. Her net profit is
displayed in the graph to the right, where x represents
the number of necklaces sold, and y represents the net
profit made. Analyze the graph to determine Jocelyn's
net profit after selling 2 necklaces.
We see that the slope intercept is y = 8x - 20. So if we substitute x with 2, because x represents the amount of necklaces sold and we are analyzing her net profit after selling 2 necklaces, that gives us y = 8(2) - 20. Which simplifies to y = -4. So by the time Jocelyn sells 2 necklaces, her net profit will be at -4.

What is an x intercept of x^2-64
Answer:
(8,0) ( -8,0) are the x intercepts
Step-by-step explanation:
Factor
x^2 - 64
This is the difference of squares
(x-8) (x+8)
Set equal to zero to find the intercepts
x-8 = 0 x+8 =0
x= 8 x= -8
Answer: (8,0) and (-8,0)
Step-by-step explanation: It is one positive and one negative 8 because a double positive would be a +64 and a double negative would also be a +64(unless there was another x for example x^2+2x-64.
x^2-64
(x+8) (x-8)
(x+8) (x-8)=0
x+8=0 and x-8=0
(-8,0) and (8,0)
What is the measure of the arc represented by the numbers 7 and 4 on a clock face? *PLS ANSWER*
Answer:
90°
Step-by-step explanation:
The clock face is a circle and represents 360°
There are 12 divisions 1- 2- 3- 4 - 5 - 6 - 7 - 8 - 9 - 10- 11 - 12 on the face
Each division = 360° ÷ 12 = 30°
There are 3 divisions between 4 and 7 , thus
arc measure = 3 × 30° = 90°
Answer:
90°

Question 4 on my algebra work: Solve the equation. (full work shown appreciated please, it's been a while since I've done a problem like this) [tex]\frac{6+n}{4} = 4[/tex]
Answer:
Option D
Step-by-step explanation:
Take a look at the steps below;
[tex]( 6 + n ) / 4 = 4,\\6 + n = 16,\\n = 10\\\\Conclusion; Solution Is 10[/tex]
To derive the second step we multiplied either side by 4, and as the 4 and 4 cancel each other out on one side of the equation, the other side being 4 * 4 = 16, we receive 6 + n = 16. The third step was found through the subtraction of 6 on either side of the equal sign. 16 - 6 = 10, so your solution is Option D

The mapping shows a relationship between input and output values.
A mapping diagram shows a relation, using arrows, between input and output for the following ordered pairs: (negative 5, 0), (2, negative 3), (negative 1, negative 3), (4, negative 2), (4, 2), (6, negative 1).
Which ordered pair could be removed to make this relation a function?
(–5, 0)
(–1, –3)
(4, –2)
(6, –1)
Answer:
(4, –2)
Step-by-step explanation:
A function has associated only one output for each input. In the ordered pairs, we can see that for the input 4 there are two associated outputs, which are -2 and 2. Then, to make the relation a function, one of them must be removed.
Answer:
(4,-2)

From the hay loft door, Ted sees his dog on the ground. The angle of depression of the dog is 40º. Ted's eye level is 16 feet above the ground. How many feet must the dog walk to reach the open barn door directly below Ted (to the nearest foot)?
Answer: 19 feet
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Tan α = opposite side / adjacent side
Where α is the angle of depression of the dog, the opposite side (16) is Ted's eye level above the ground, and the adjacent side (x) is the distance between the dog and the barn door.
Replacing with the values given:
tan40 = 16/x
Solving for x
x =16/tan40
x= 19 ft

A music store bought a CD set at a cost of $25. When the store sold the CD set, the percent
markup was 35%. Find the selling price.
Answer:
$33.75
Step-by-step explanation:
The selling Price is $33.75.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A music store bought a CD set at a cost of $25.
Markup Percent= 35%
Now, the Selling Price
= 25 + 25 x 35%
= 25 + 25 x 35/100
= 25 + 25 x 0.35
= 25 + 8.75
= $33.75
Hence, the selling Price is $33.75.

a CD player regularly sells for $80. It is on sale for 20% off. What is the sale price of the CD player?
-_______________________________
Hey,
Solution,
Marked price(MP)= $ 80
Discount percent= 20%
Now,
Discount amount=discount percent of MP
= 20% of 80
=20/100*80
= $ 16
Again,
Selling price(SP)=MP - Discount amount
=$80 -$16
=$64
So,the sale price of the CD player is $ 64.
Hope it helps...

About 11.31 cm
Step-by-step explanation:
If one of the legs of a right iscosceles triangle is 8, then the length of the other one must also be 8. Therefore, by the Pythagorean Theorem:
[tex]h=\sqrt{8^2+8^2}=\sqrt{64+64}=\sqrt{128}\approx11.31[/tex]
Hope this helps!
Solution,
Hypotenuse=?
Perpendicular=8 cm
Base=8cm
Now,
Using Pythagoras theorem,
h^2=p^2+b^2
or,h^2=(8)^2+(8)^2
or,h^2=64+64
or,h^2=128
or,h=√128
or,h=8√2
h=11.31 cm

Alex has 70% of her weekly paycheck automatically deposited into a savings account. this week $35. Alex wants to know the total amount of her paycheck this week.
Answer: The total amount of her paycheck this week is $50
Step-by-step explanation:
Hi, the full question is :
Alex is 70% of her weekly paycheck automatically deposited into a savings account. This week $35 is deposited. Alex wants to know the total amount of your paycheck this week.
So, to answer this question we have to write an equation and solve for x (total amount of the paycheck).
Since 70% of her weekly paycheck is automatically deposited into a savings account. and this week $35 is deposited, we have to multiply the total amount of the paycheck (x) by the percentage deposited in decimal form (70/100), that expression must be equal to the amount deposited (35)
x (70/100) = 35
Solving for x:
x (0.7) =35
x = 35/0.7
x = $50
Answer:
Step-by-step explAlex is 70% of her weekly paycheck automatically deposited into a savings account. This week $35 is deposited. Alex wants to know the total amount of your paycheck this week.
