Answer:
It's of science not of mathematics
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{10 \: N}}}}}[/tex]
Step-by-step explanation:
Given,
Load distance ( LD ) = 2m
Load ( L ) = 800 N
Effort distance ( ED ) = 160 m
Effort ( E ) = ?
Finding the Effort applied
Apply the principal of simple machine :
[tex] \boxed{ \sf{L \times LD = E\times ED}}[/tex]
[tex] \longrightarrow{ \sf{800 \times 2 = E \times 160}}[/tex]
[tex] \longrightarrow{ \sf{1600 = 160 \: E}}[/tex]
[tex] \longrightarrow{ \sf{160E = 1600}}[/tex]
[tex] \longrightarrow{ \sf{ \frac{160E}{160} = \frac{1600}{160} }}[/tex]

A pyramid with a rectangular base has a volume of 105 cubic centimeters and a height of 15 centimeters. The length of the rectangular base is 7 centimeters. Find the width of the rectangular base.
Answer:
Hey there!
V=lwh/3
315=lwh
315=15(7)w
315=105w
width=3
Hope this helps :)
The width of the rectangular base of the pyramid is W = 3 centimeters
What is the volume of a pyramid?The volume of a pyramid, is the product of the area of its base with the height of the pyramid, and divide by 3. We express this product with the formula V = ( 1/3) ×B×h, where B is the area of the base of the pyramid, and h is its height.
Volume of Pyramid = ( 1/3 )a²H
Given data ,
Let the volume of the pyramid be represented as V
Now , the value of V is
V = 105 cm³
And , the length of the pyramid L = 7 cm
The height of the pyramid is H = 15 cm
Let the width of the pyramid be W
And , Volume of Pyramid = ( 1/3 ) ( L x W x H )
105 = ( 1/3 ) ( W x 15 x 7 )
On simplifying , we get
105 ( W ) ( 1/3 ) = 105
Divide by 105 on both sides , we get
W / 3 = 1
Multiply by 3 on both sides , we get
W = 3 cm
Therefore , the value of W is 3 cm
Hence , the width of pyramid is 3 cm

An error has been made in subtracting the two polynomials as shown in the student work. (6x2 – 4x – 5 ) – (3x2 – 7x + 2) = How do you correctly subtract the two polynomials? Identify: Terms: Coefficient of "x2 ":Coefficient of "x":
Answer:
3x^2 + 3x - 7
Step-by-step explanation:
Given:
(6x^2 – 4x – 5 ) – (3x^2 – 7x + 2)
The correct way of subtracting the polynomial is by changing the sign of each term of the second polynomial. Like this
= 6x^2 – 4x – 5 – 3x^2 + 7x - 2
Collect like terms
= 6x^2 - 3x^2 - 4x + 7x - 5 - 2
Simplify
= 3x^2 + 3x - 7
(6x^2 – 4x – 5 ) – (3x^2 – 7x + 2) = 3x^2 + 3x - 7
From the answer, the coefficient of x^2 is 3, coefficient of x is 3
Find how long it takes a person to drive 94 miles on a highway if she merged into a highway at 1pm and drives nonstop with her cruise control set on 40mph
Answer:
2.35 hrs
If she merged the highway at 1 pm, then she'll leave the highway by 3:21 pm
Step-by-step explanation:
distance traveled = 94 miles
cruise speed = 40 mph
time taken = ?
time taken = distance/speed = 94/40 = 2.35 hours
2.35 hrs = 2 hrs + (0.35 x 60) = 2 hrs + 21 min
If she merged the highway at 1 pm, then she'll leave the highway by 3:21 pm

The pinata weighs 11/4 pounds without candy.He adds 8bags that weighs 3/8,3/8,1/2,1/2,1/2,3/4,3,11/4 how much will the pinata weigh when it is filled with the eight bags of candy
Answer:
[tex]Weight = \frac{23}{2}[/tex]
Step-by-step explanation:
Given
Weight of Pinata = 11/4 lb
Weight of candies = 3/8, 3/8, 1/2 , 1/2, 1/2, 3/4, 3, 11/4
Required
Weight of Pinata when filled with candies
To solve this question, we simply need to add all weights together
First, we need to add up the weight of the candies
[tex]Candies = \frac{3}{8} + \frac{3}{8} + \frac{1}{2}+ \frac{1}{2}+ \frac{1}{2}+ \frac{3}{4} + 3 + \frac{11}{4}[/tex]
Take LCM
[tex]Candies = \frac{3 + 3 + 4 +4 + 4 + 6 + 24 + 22}{8}[/tex]
[tex]Candies = \frac{70}{8}[/tex]
Simplify:
[tex]Candies = \frac{35}{4}[/tex]
Next; Add the weight of the candies to the weight of pinata
[tex]Weight = Candies + Pinata[/tex]
[tex]Weight = \frac{35}{4} + \frac{11}{4}[/tex]
Take LCM
[tex]Weight = \frac{35 + 11}{4}[/tex]
[tex]Weight = \frac{46}{4}[/tex]
Simplify
[tex]Weight = \frac{23}{2}[/tex]
Hence, the weight of the Pinata after it is filled with candies is 23/2 lb

then you add: 15 + 18h = 33h
(just add 15 and 18 then add h on the end)
Three houses A B and Clie on the same line on a map. House Blies exactly in the middle of house A and house C The point (3,6) on the
map represents house A and the point (-5-3) represents house B.
Find the coordinates of house Con the map
Answer:
(-13, -12)
Step-by-step explanation:
The midpoint (x,y) between two points ([tex]x_1,y_1[/tex]) and ([tex]x_2,y_2[/tex]) on the coordinate plane is given by:
[tex]x=\frac{x_1+x_2}{2};\\\\y=\frac{y_1+y_2}{2}[/tex]
Hence given that house A is at (3, 6) and house B is at (-5, -3). Since house B is placed at the middle of house A and house B, let the coordinates of house C be ([tex]x_2,y_2[/tex]). Hence:
[tex]-5=\frac{3+x_2}{2\\} \\3+x_2=-10\\\\x_2=-10-3\\\\x_2=-13[/tex]
[tex]-3=\frac{6+y_2}{2\\} \\6+y_2=-6\\\\y_2=-6-6\\\\y_2=-12[/tex]
Therefore house C is at (-13, -12)
How many grams NaCl would you use to make a 4M solution in 100ml
Answer:
Amount of NaCl = 23.376 gram
Step-by-step explanation:
Given:
Molarity = 4M
Volume of solution = 100 ml
Find:
Amount of NaCl
Computation:
Molar mass of Na = 22.99 g/mole
Molar mass of Cl = 35.45 g/mole
Molar mass of NaCl = 22.99 + 35.45
Molar mass of NaCl = 58.44 g/mole
Molarity = [moles of solute / volume of solute(ml)]1,000
4 = [moles of solute / 100]1000
Moles of solute = 0.4
moles of solute = Mass of solute / molar mass
0.4 = Amount of NaCl / 58.44
Amount of NaCl = 23.376 gram

Marcie wants to enclose her yard with a fence. Her yard is in the shape of a rectangle attached to a triangle. The formula for the area of the enclosed space is A=lw+0.5bh. Solve for b
Answer:
b = (A - lw) / 0.5h
Step-by-step explanation:
The formula for area of the enclosed place is
A=lw+0.5bh
Where,
A= Area of the enclosed space
l= length of the rectangle
w= width of the rectangle
b= base of the triangle
h= height of the triangle
A=lw+0.5bh
Solve for b
A=lw+0.5bh
Subtract lw from both sides
A - lw = lw + 0.5bh - lw
A - lw = 0.5bh
Divide both sides by 0.5h
(A - lw) / 0.5h = (0.5bh) / 0.5h
(A - lw) / 0.5h = b
Therefore,
b = (A - lw) / 0.5h
Answer:
b= A-lw over 0.5h

The Theodore Teddy Bear Company can pack 48 medium size bears in a carton. They received an order for 500 medium bears from the Canadian Traveling Carnival. Estimate the number of cartons needed to ship the order.
Answer:
11 cartons.
Step-by-step explanation:
Since only 48 bears can be fitted into 1 carton, we need to find how many cartons approximately 500 bears can fit in:
500/48 = 10.4167 cartons
We can't have 4/10ths of a carton. Makes no sense in the real world. Therefore, we need a total of 11 cartons to pack 500 bears, even if one box isn't full.
