The safe load for a horizontal beam supported at both ends varies
jointly as the width and the square of its depth and inversely as
the distance between the supports. If a 4 cm by 6 cm beam,
10 m long supports 5 kg when standing on the edge, what is the
safe load if the beam is turned on its side?
Answer:
The formula would be
wd^2c/l = p
(2*1^2c)/4 = 10
(2*1c)/4 = 10
2c/4 = 10
c = 20
3*2^2*20/6 = p
3*4*20/6 = p
240 pounds
hope it help :)
Step-by-step explanation:
The safe load if the beam is turned on its side will be 240 pounds.
What is a load?A burden or pressure source that is carried by someone or something. Construction loads are defined as the weights placed on an existing or temporary structure both during and after the construction process.
Given that the safe load for a horizontal beam supported at both ends varies jointly with the width and the square of its depth and inversely with the distance between the supports. If a 4 cm by 6 cm beam, 10 m long supports 5 kg when standing on the edge,
The load will be calculated by using the formula below:-
wd²c/l = p
(2 x( 1 ) ²c)/4 = 10
(2x 1c)/4 = 10
2c/4 = 10
c = 20
3 x ( 2 )²x ( 20/6 ) = p
3 x 4x ( 20/6 ) = p
p = 240 pounds
Therefore, the safe load if the beam is turned on its side will be 240 pounds.

|8x+3|=12 what’s the answer
Answer:
x= 9/8 , -15/8
Step-by-step explanation:
Answer:
x = 1.125 , x = 9/8
Step-by-step explanation:
|8x+3| = 12
=> 8x + 3 = 12
=> 8x = 12-3 = 9
=> 8x = 9
=> x = 9/8
As 9/8 is a fraction let's make it a decimal.
9/8 * 125/125 (To make it into a power of ten so that we can convert)
=> 1125 / 1000
=> 1.125

Simple geometry that I don’t know cuz I’m a dum dum
Helpp meee pleaseeeeeeeeeee !!!!
Step-by-step explanation:
since the domain of the function is given, you just have to plug in the numbers to the function:
13x - x²
it's basically asking: if x was any of the numbers in the given domain, what would it be the answer be?
for example:
I'll solve for -2 and you can do the rest.
13 • -2 -(-2 ²) =
13 • 2 + 4 =
26 + 4 = 30
so the range for -2 would be 30
Create two tables with at least four coordinates each. In the first table, choose coordinates that make the relation a function. In the second table, choose coordinates that don't make the relation a function. Explain in complete sentences how you determined which coordinates would define a function and which coordinates would not.

Answer:
function: (1, 98), (2, 98), (3, 2), (4, -86)not a function: (1, 98), (2, 98), (3, 2), (3, -86)Step-by-step explanation:
A relation that is a function has unique x-values. A relation that is not a function has at least one x-value that is repeated. The y-values do not need to be unique in either case, except that a repeat of the same (x, y) pair does not disqualify a relation from being a function.
In the table shown above, the non-function has the x-value of 3 repeated with different y-values.

If f (x) = one-ninth x minus 2, what is f>1(x)
Answer: f-1(x) = 9x + 18.
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x - 2 ( add 2 to both sides )
y + 2 = x
Multiply through by 9 to clear the fraction
9y + 18 = x
Change y back into terms of x
(x) = 9x + 18
Answer:
Answer: f-1(x) = 9x + 18.

A deluxe bakery sells a cookie for $2.38, a brownie for $3.07 and a cake for $14.87. On Wednesday they sold 13 cookies, 4 brownies and 4 cakes. The cost in ingredients for each cookie is $1.7, for each brownie is $1.91 and for each cake is $5.83. How much profit did they make on Wednesday?
Answer:
$ 49.64
Step-by-step explanation:
Selling price of cookie on Wednesday = 13 × 2.38 = $30.94
Selling price for brownie on Wednesday = 4 × 3.07 = $ 12.28
Selling price for cakes on Wednesday = 4 × 14.87 = $ 59.48
Cost price for cookie = 13 × 1.7 = $ 22.1
Cost price for brownie = 4 × 1.91 = $ 7.64
Cost price for cakes = 4 × 5.83 =$ 23.32
Total profit for Wednesday= Total selling price - total cost price
That is;
(30.94 + 12.28 + 59.48) - (22.1 + 7.64 +23.32) = $ 49.64

Step-by-step explanation:
B 27 bags of chips by 5 people
Answer:
B) 5 people share 27 brownies.
Step-by-step explanation:
This is the answer because:
1) If 5 people are sharing 27 brownies, it means they are basically asking, how many brownies did each person get. Then, we would write the numerical sentence: 27 ÷ 5 because we want to know how many brownies each person got.

Joseph runs 2 miles on Monday. Each day after that, he runs the same 1 mile route every morning. His goal is to run at least 6 miles
by the end of the week. Which inequality represents the least number of days after Monday that Joseph needs to run to reach his goal?
Sine he runs 2 miles on Monday, we already have a +2.
Then, he runs by a constant rate of 1, which is the constant rate of change per day.
Let x represent the number of days he runs and y the total amount of miles he runs. Now, the equation is y = x + 2
However, he needs to run at least 6 miles. At least means greater than or equal to. The values for y can be greater than 6, or equal to 6.
y ≥ 6
y = x + 2
Now substitute x + 2 for y.
x + 2 ≥ 6
Subtract 2.
x ≥ 4
This is the inequality. He has to run for at least 4 days.
