A baker starts with 100 pounds of flour. He uses the following quantities in one day: 3 3/8 lb, 18.25 lb, 8.6125 lb, 7 3/4 lb, and three recipes each requiring 5 7/16 lb. How much flour is left at the end of the day?
Answer:
45.7 lb
Step-by-step explanation:
3 3 /8 = 3.375 lb
18.25 lb
8.6125 lb
7 3/4 = 7.75 lb
5 7/16 = 5.4375 lb
Flour required of 3 recipes = 3 * 5.4375 = 16.3125 lb
3.3750 +
18.2500 +
8.6125 +
7.7500 +
16.3125
Quantity of flour used in a day = 54.3000 lb
Quantity of left at the end of the day = 100 - 54.3
= 45.7 lb
find the sum of even numbers between 1001 and 10,000 (Arithmetic progressions) DO STEP BY STEP PLEASE
Step-by-step explanation:
arithmetic progression
even numbers between 1001 and 10000
1002,1004,.......9998
Tn=a+(n-1)d
Tn = 9998 last term in the progression of even numbers
a = 1002 first term
d = 2 distance
9998=1002+(n-1)(2)
8996=2n-2
8998=2n
n = 4499 the number of terms
sum = n/2 (a+Tn) = 4499/2(1002+9998)
= (4499/2)(11000) = 24744500
Logic:
notice what happens when you add the first and last terms
1002+9998=11000
1004+9996=11000

B. Via-0)2 + (0-0) - V-a
C. (2-0)2 + (0-0)2 =
D. V-0)? +(5-6)2 - 12 -
= a
Answer:
[tex]Distance = \sqrt{(0 - a)^2 + (0 - 0)^2}[/tex]
[tex]Distance = a[/tex]
Step-by-step explanation:
Given
[tex]A = (0,0)[/tex]
[tex]B = (a,0)[/tex]
[tex]C = (a,b)[/tex]
[tex]D = (0,b)[/tex]
Required
Determine the distance between A and B
The distance between points is calculated as thus;
[tex]Distance = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
Considering points A and B
[tex]A(x_1,y_1) = (0,0)[/tex]
[tex]B(x_2,y_2) = (a,0)[/tex]
Substitute values for [tex]x_1, x_2, y_1[/tex] and [tex]y_2[/tex] in the above formula
[tex]Distance = \sqrt{(0 - a)^2 + (0 - 0)^2}[/tex]
The above expression represents the distance between A and B;
However, it can be solved further as thus
[tex]Distance = \sqrt{( -a)^2 + (0)^2}[/tex]
[tex]Distance = \sqrt{a^2 + 0}[/tex]
[tex]Distance = \sqrt{a^2}[/tex]
[tex]Distance = a[/tex]
Hence, the distance between A and B is a

(20 POINTS!!!) Bob can paint a room in 3 hours, and Suzie can paint one in 2 hours. How long will it take them together to paint a room?
Answer:
1 hour 12 minutes or 1.2 hours
Step-by-step explanation:
You add fractions to get this.
1 room/3 hours + 1 room / 2 hours = 1 room / x
0.33333333+0.5 = 1 room / x
0.83333333 = 1 / x Multiply both sides by x
0.83333333x = 1 Divide by 0.8333333
x = 1/0.833333
x = 1.2 hours or
x = 1 hour and 12 minutes
At the grocery store, you can purchase lemons at 2 for $0.99. you can also buy a bag of 6 lemons for $2.50. Which is the better buy?
Answer:
Purchasing the bag of 6 lemons is the better buy.
Step-by-step explanation:
There are two ways that we can do this: find the unit rate or find how the LCM.
---
The first way is more orthodox, and you should definitely use it in harder problems. We can set up two ratios like so.
2 : 0.99
6 : 2.5
Let's simplify the ratios so the left side is one.
2 : 0.99 = 1 : 0.495 by dividing both sides by 2.
6 : 2.5 = 1 : 0.41666... by dividing both sides by 6.
Comparing the two ratios, we can conclude that the second one is smaller, therefore the bag of 6 lemons costs less.
---
The second way, although not very efficient with big numbers, works well with small numbers like these.
First, we need to find the LCM, or the least common multiple. The LCM of 2 and 6 is 6, as 6 is a multiple of both 2 and itself.
Now we must make the amount of lemons match each other so we can compare the price.
2 : 0.99 = 6 : 2.97 by multiplying by 3.
The second ratio stays the same.
2.50 is smaller than 2.97, so the second ratio is smaller than the first, reaching our previous conclusion.

Answer: x= 3/2 and y= 1/2
Step-by-step explanation:
Since both equations are equated to y, you just need to use substitution to create the equation below:
-x+2 = 3x-4
Solve the equation for x:
4x=6
x=6/4=3/2
Plug in x into any one of the given equations to find the value of y:
y=-x+2
y= - (3/2)+2
y= - (3/2)+4/2
y= 1/2

The solution to the system of equations will be x= 3/2 and y= 1/2.
What is a system of equations?A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.
An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
The given equations are y=−x+2 and y=3x−4 to calculate the values of x and y using the substitution method.
Since both equations are equated to y, you just need to use substitution to create the equation below:
-x+2 = 3x-4
Solve the equation for x:
4x =6
x =6/4=3/2
Plug x into any one of the given equations to find the value of y:
y =-x+2
Solve for the value of y.
y = - (3/2)+2
y = - (3/2)+4/2
y = 1/2
Hence, the solution for the equation will be x= 3/2 and y= 1/2.

HELP!!!! PLEASE! 10 POINTS Which function is graphed?
Answer:
f(x)=2x-6
Step-by-step explanation:
Because the slope is 2 and the y-intercept is -6.
[tex]x[/tex]Answer:
The answer would be [tex]f(x)=2x-6[/tex]
Step-by-step explanation:
The question is basically asking for the slope intercept form and [tex]f(x)[/tex] is equal to [tex]y[/tex]. So after we have figured that out we would have to know what the slope intercept form is, slope intercept form is simply [tex]y=mx+b[/tex]. In the equation [tex]m[/tex] will equal the slope or the rise over run and [tex]b[/tex] will equal the y-intercept and that is all we need to solve this equation.
If we look at the graph we will see that the line crosses the y axis at the point (0,-6) so knowing that we will remember that [tex]b[/tex] is the y-intercept is where the line crosses the y axis and in this case it is crossing it at -6 so if we plug that into the equation we will get [tex]y=mx-6[/tex].
Now we will find the slope or [tex]m[/tex]. First we will see the distance between the 2 points on the graph, if we count we will have to go up 6 to get to (0,0) and we will go right 3 so we know that slope is rise over run so you would go up or rise 6 and go right or run 3 so we would get [tex]\frac{6}{3}[/tex] as our slope, but we could simplify this to just 2 so we would get [tex]2x[/tex] as our [tex]mx[/tex].
We have solved all of the parts and now we can put it together. So first we would do f of x or [tex]f(x)[/tex] which means function and than we would put [tex]2x[/tex] and finally we would put our [tex]-6[/tex]. When we put that all together we would get [tex]f(x)=2x-6[/tex].
To check you could just graph this and you would get:

Answer:
6
Step-by-step explanation:
To find the GCF do the prime factorization of each term
24: 2x2x2x3
18t: 2x3x3xt
Now find the numbers that they both have in common
That would be 2 & 3
When you multiply them together you should get 6
This is the same as 6(3t + 4) because we can add two terms in any order
To get either answer, we first note that 6 is the greatest common factor (GCF) of 18 and 24. So we factor each term so that a 6 is involved. Then we use the distributive property in reverse like so
24 + 18t = 6*4 + 6*3t = 6(4 + 3t)
The distributive property is a(b+c) = a*b + a*c. We multiply the outer term 'a' by each term inside the parenthesis. Then we add the results.

Answer:
20 or 55
Step-by-step explanation:
It depends because i am not sure what f(x) is.
Case 1: f(x)=x^2
We know h(x)=7 hence f(h(x))=7^2=49 hence g(f(h(x)))=49+6=55
Case 2: f(x)=x*2
We know h(x)=7 hence f(h(x))=2*7=14 hence g(f(h(x)))=14+6=20
Note: x^2 is x to the power of 2 while x*2 is x times 2.

Answer:
18.9 ft²
Step-by-step explanation:
Surface area of this cylinder = area of the bottom and top circles + area of the curved surface.
Area of the two circles = 2πr² , where r is the radius.
Area of the curved surface = 2πrh , where r is the radius and h is the height.
Radius = [tex]\frac{1}{2}[/tex] × diameter
Area of the two circles = 2 × π × ([tex]\frac{2}{2}[/tex])² = 6.3 ft² (answer rounded up to nearest tenth)
Area of the curved surface = π × diameter × h = π × 2ft × 2ft = 12.6 ft² (answer rounded up to nearest tenth)
