The ratio of melanie's allowance to jacob's allowance is 4.1 to 20.5. If Jacob gets $5.00,how much allowance does melanie get?
Answer:
1.00
Step-by-step explanation:
x=(5*4.1)20.5
x=1
x^2-4x+6x-24 factored
Answer: (X+6)(x-4)
Step-by-step explanation:
x^2-4x+6x-24 ==> x^2+2x-24
*Find two numbers that multiplied gives you -24 and add up to 2*
(6)(-4)= -24 6-4=2
Final result= (x+6)(x-4)
A 4 pound force acting in the direction of (4,-2) moves an object just over 7 ft from point (0,4) to point (5,-1). Find the work done to move the object to the nearest foot-pound
Answer:
[tex]W=59.7408J[/tex]
Step-by-step explanation:
From the question we are told that:
Force [tex]f=4N[/tex]
Force Direction [tex]\arrow (4,-2)[/tex]
Distance traveled [tex]d_t=7ft \aprrox\ 2.1336m[/tex]
Distance traveled Direction point (0,4) to point (5,-1)
Generally the equation for work done is mathematically given by
[tex]W=force*distance[/tex]
[tex]W=f*d_t\\W=4*7*2.1336[/tex]
[tex]W=59.7408J[/tex]
Maria adds 3 cards to her stack of 60. She says now there are only two ways to
arrange the cards into equal groups. Her reason is that 63 is an odd number. Is Maria's
reasoning correct? Explain why or why not.
Answer:
63 is an odd number because the singular number 3 is odd meaning there will be some cards left over.
Maria's reasoning is incorrect. Because, The fact that 63 is an odd number does not necessarily mean that there are only two ways to arrange the cards into equal groups.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
To determine the number of ways that the cards can be arranged into equal groups, we need to consider the factors of 63. In this case, the factors of 63 are 1, 3, 7, 9, 21, and 63. This means that there are six possible ways to arrange the cards into equal groups of any of these factors:
1 group of 63 cards
3 groups of 21 cards
7 groups of 9 cards
9 groups of 7 cards
21 groups of 3 cards
63 groups of 1 card
So, Maria's reasoning is not correct. There are actually six ways to arrange the cards into equal groups, based on the factors of 63.

Step-by-step explanation:
A circle has a radius of 8. Find the area of a sector of this circle that is intercepted by central angle measuring pi over 7
Answer:
14.4 square units
Step-by-step explanation:
Keep in mind that the area here is a fraction of the area of a full circle of radius 8.
(area of sector) = (fraction)(pi)(8)^2
The fraction is the given central angle (pi over 7) divided by 2pi:
pi 1
--------- * ----------- = 1/14
7 2pi
Multiply the formula (fraction)(pi)(8)^2 found above by this fraction:
area of sector = (1/14)(pi)(8)^2 = 14.4 square units
A coach is buying snacks for 22 players on a soccer match chip is a total of $77 to buy each player a bottle of water and energy bar the price of one energy bar is two dollars
The question is incomplete:
A coach is buying snacks for 22 players at a soccer match. She pays a total of $77 to buy each player a bottle of water and an energy bar. The price of one energy bar is $2. Let w equal the price of a bottle of water. Write an equation that represents the situation.
Answer:
x=44+22w, where
x is the total amount paid
w is the price of a bottle of water
Step-by-step explanation:
With the information provided, you can say that the total amount paid is equal to the result of multiplying the price per energy bar for the number of energy bars purchased plus the result of multiplying the price per bottle of water for the number of bottles of water:
price per energy bar= $2
number of enrgy bars= 22
price per bottle of water= w
number of bottles of water= 22
x=(2*22)+(w*22)
x=44+22w, where
x is the total amount paid
w is the price of a bottle of water

what is 4(11h +3g)?????
Answer:
[tex]12g+44h[/tex]
Step-by-step explanation:
Step 1: Rearrange terms
[tex]4(11h+3g)\to4(3g+11h)[/tex]
Step 2: Distribute
[tex]4(3g+11h)\to12g+44h[/tex]
Answer:
44h+12g
Step-by-step explanation:
Okay, so, this a standard algebraic expanding problem, so:
We take our 4(11h + 3g)
because we have parenthesis, we have to distribute the 4:
4 x 11h + 4 x 3g = 44h + 12g
So, 4(11h + 3g) expanded is 44h + 12g

FalseTrueTrueFalseTrueFalse===============================================
Explanations:
If we can write a number as a ratio (or fraction) of two whole numbers, then that number is considered rational. The denominator can never be 0. In the case of 6/4, this is a rational number. Therefore, the statement "6/4 is irrational" is false. This is a true statement. We cannot write sqrt(2) as a fraction of two integers. The proof of this is fairly lengthy, but one way is to use a proof by contradiction to show that sqrt(2) = a/b is impossible. Since we cannot make sqrt(2) into a ratio of two integers, we consider it irrational.This is a true statement. Any terminating decimal is always rational. In this case, 1.3 = 13/10.This is false. Any repeating decimal can be converted to a fraction through a bit of work. It turns out that 17.979797... = 1780/99 which makes the value to be rational.Any integer is rational. We can write the integer over 1. So something like -16 is the same as -16/1, showing how it is rational. So that's why this statement is true.This statement is false because we found true statements earlier.Solve the quadratic equation by using the quadratic formula 3x^2x-3=0
