Elena needs 1/4 meter of ribbon to decorate the border of a photo frame.
Enter the number of photo frames that can be decorated using 3/4 meter of ribbon.
Answer:
3 photo frames
Step-by-step explanation:
1 frame uses 1/4 meters. You can solve this as a proportion. 1 is to 1/4 and x is to 3/4. 1/4 x 3 is 3/4. So multiply 3 x 1 as well. You get 3.

20
Answer:
b= 20 • c
b is equalled to how many bottles, which c is equalled to how many cases, since there is no number for how many cases then is just the variable "c".
The equation representing the number of bottles is c = 20b
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x - 5 = 16 is an equation.
Given that, Madison ordered c cases of the bottle with each case having 20 bottles,
So, for c cases she will have 20b bottles.
The equation is :-
c = 20b
Here,
c is dependent variable
b is independent variable
Hence, the equation representing the number of bottles is c = 20b

What single decimal multiplier would you use to increase by 5% followed by a 20% increase?
Answer:
The single decimal multiplier is 1.26.
Step-by-step explanation:
Multipliers:
For a decrease of a%, we multiply by: [tex]\frac{100-a}{100}[/tex]
For a increase of a%, we multiply by: [tex]\frac{100+a}{100}[/tex]
For consecutive changes, we multiply the multipliers.
Increase of 5%
Multiply by [tex]\frac{100+5}{100} = \frac{105}{100} = 1.05[/tex]
Increase of 20%
Multiply by [tex]\frac{100+20}{100} = \frac{120}{100} = 1.2[/tex]
Consecutive:
1.05*1.2 = 1.26
The single decimal multiplier is 1.26.

HELP PLEASE ASAP !!!
Answer: 398765
=====================================================
Work Shown:
x = total number of copies sold so far
8.1% of x = 0.081*x = amount of copies sold in the first month
0.081*x = 32300
x = 32300/0.081
x = 398,765.432098766
x = 398,765
Rounding to the nearest whole number, about 398,765 copies have been sold so far to date.
A horse can run at a top speed of 18 1/5 miles in 1/3 hour. What is the unit rate of the top running speed of a horse in miles per hour?
Answer:
54.6
Step-by-step explanation:
(18⅕ miles)/(⅓ hour) = ((18⅕)×3 miles)/hour = 54.6 miles per hour
The unit rate of the top running speed of a horse in miles per hour is 54.6 miles per hour.
What is the unit rate?There is an independent quantity, and a quantity that depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called the rate of increment of dependent quantity per unit increment in independent quantity.
Speed can be calculated as the ratio of the distance traveled to the time taken by the object.
We have been given that horses can run at a top speed of 18⅕ miles in 1/3 hour.
Therefore, Distance = 18⅕ miles
Speed = 18⅕ miles in 1/3 hour.
Thus, we get;
Unit rate= (18⅕ miles) / (⅓ hour)
Unit rate = ((18⅕)×3 miles)/hour
Unit rate = 54.6 miles per hour
Therefore, the unit rate of the top running speed of a horse in miles per hour is 54.6 miles per hour.

how do i convert to slope intercept form
Answer:
y = x - 8
Step-by-step explanation:
Slope intercept form: y = mx + b, where b is the y-intercept.
Solve the given equation for y and then compare the result with this y = mx + b:
3y = 3x - 24
Dividing all three terms by 3 yields:
y = x - 8 (answer). The slope is 1 and the y-intercept is -8.
Ashlyn and her friends are making gingerbread houses. They need to divide 28 packages of gumdrops between 7 friends. There are 25 gumdrops in each package. How many gumdrops will each friend get?
Answer:
100 gumdrops per person
Step-by-step explanation:
We know that there are 28 packages and each one has 25. So just multiply 28 by 25 and you get 700 gumdrops in total. Finally because there are seven friends in total you divide 700 by 7 and get 100 per person.

Answer:

Step-by-step explanation:
3(x-4)= 2(x + 5)
Find the number
Answer:
x=22
Step-by-step explanation:
Reorder the terms:
3(-4 + x) = 2(x + 5)
(-4 * 3 + x * 3) = 2(x + 5)
(-12 + 3x) = 2(x + 5)
Reorder the terms:
-12 + 3x = 2(5 + x)
-12 + 3x = (5 * 2 + x * 2)
-12 + 3x = (10 + 2x)
Solving
-12 + 3x = 10 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
-12 + 3x + -2x = 10 + 2x + -2x
Combine like terms: 3x + -2x = 1x
-12 + 1x = 10 + 2x + -2x
Combine like terms: 2x + -2x = 0
-12 + 1x = 10 + 0
-12 + 1x = 10
Add '12' to each side of the equation.
-12 + 12 + 1x = 10 + 12
Combine like terms: -12 + 12 = 0
0 + 1x = 10 + 12
1x = 10 + 12
Combine like terms: 10 + 12 = 22
1x = 22
Divide each side by '1'.
x = 22
Simplifying
x = 22

The arcs on the Golden Gate Bridge.
I think about the Golden Gate Bridge, which is a suspension bridge.
As in any suspension bridge, a long cable is supported by two large supports.
The cable falls from support, in the form of a curve concave upwards, to a minimum point that is the vertex of the parabola, through which the axis of symmetry passes, and curves again upwards to ascend to the upper end of the other support.
As a unique feature of this parabolic arc, you can tell that the concavity is upward; the parabola opens upward.
Also, you can tell that the parabola is vertical, which means that the axis of symmetry is vertical.
The symmetry is clear because the curve to the left of the vertex is a mirror image of the curve to the right of the vertex. Hope I helped, have a good day!
