Answer:
the leftover piece of ribbon is 5 3/4 feet long.
Step-by-step explanation:
if she has 7 1/2 feet of ribbon, and she removes (by cutting it off) 1 3/4 feet of ribbon.
So, if we set up this scenario like a math problem, we can write it as this:
7 1/2 feet of ribbon - 1 3/4 feet of ribbon = remaining ribbon
[ - = take away]
so, we are solving the equation:
7 1/2 - 1 3/4
To solve this, it is easiest to make the fractions have the same denominators
1 / 2 is equal to 2 / 4
However, 2/4 is less than 3/4, so we need to make this fraction a larger number.
To do this, we can take away 1 foot from the 7, and write it as if it were fourths
1 [foot] = 4/4 quarter foot
So, we can add 4/4 + 2/4 = 6/4
Now, we can re-write our situation.
6 6/4 - 1 3/4 = left over ribbon
6 6/4
- 1 3/4
__________
5 3/4
So, the leftover piece of ribbon is 5 3/4 feet long.
Hope this helps!

Help please I’ll make it brainliest!!!!!
Step-by-step explanation:
it is very simple, once you remember that "kilo" means 1000, "mili" means 1/1000, and "centi" means 1/100.
and therefore 1 cg = 10 mg, or 1 cm = 10 mm.
"deci" means 1/10.
and therefore 1 dm = 100 mm, 1dg = 100 mg.
1.
9.32 kg = 9.32×1000 = 9320 g
2.
1.429 g = 1.429/1000 = 0.001429 kg
3.
287 g = 287/1000 = 0.287 kg
4.
4.6 L = 4.6×1000 = 4600 mL
5.
0.119 L = 0.119×1000 = 119 mL
6.
9936 mL = 9936/1000 = 9.936 L
7.
26793 mL = 26793/1000 = 26.793 L
8.
0.06 L = 0.06×1000 = 60 mL
9.
170 cg = 170×10 = 1700 mg
10.
2674 cm = 2674/100 = 26.74 m
11.
9.05 mm = 9.05/100 = 0.0905 dm
12.
2 L = 2×1000 = 2000 mL
13.
62.4 L = 62.4×1000 = 62400 mL
14.
99.9 mm = 99.9/1000 = 0.0999 m
15.
4.34 g = 4.34×100 = 434 cg
16.
10 km = 10×1000 m = 10×1000×1000 = 10000000 mm
17.
65 cL = 65/100 = 0.65 L
18.
105 mL = 105/1000 = 0.105 L
19.
0.27 g = 0.27×100 = 27 cg
20.
7777 m = 7777/1000 = 7.777 km

if f(x)=2x-1 and g(x)=x^2-4, what is g(f(x))
Answer:
4x^2 - 4x - 3
Step-by-step explanation:
f(x) = 2x - 1
g(x) = x^2 - 4
g(f(x)) = ?
[substitute the x of g(x) with f(x)]
g(x) = x^2 - 4
g(f(x)) = (2x - 1)^2 - 4
[solve]
[binomial * binomial = quadratic equation]
[use FOIL method (first, outer, inner, last)]
g(f(x)) = (2x - 1)(2x - 1) - 4
g(f(x)) = (2x*2x) + (-2x) + (-2x) + (1) - 4
[combine like terms]
g(f(x)) = 4x^2 - 2x - 2x + 1 - 4
g(f(x)) = 4x^2 - 4x - 3
Today only a table is being sold for $364.89. This is 38% of its regular price. What was the price yesterday

OC. 4x b≤ $102
OD. 4+ b< $102
If you help me I will give 100 points
Answer:
b
Step-by-step explanation:
because it is 4 dolls and x is the amount of dollars 1 doll is and 4x dolls are less then 102, the only answer that makes sense is b
The answer is B. I will choose to explain by process of elimination. It is not A because it is not less than or equal to, it is just less than. Therefore, we can also eliminate C. It is not D because it is four dolls that cost the same so it is 4x instead of 4+x. I hope I helped!

They measure the height of the plant at the end of each week for several weeks and display the data in a scatter plot. They then find the equation for the best-fit line to be y= 2.5 + 1.25x
X = the number of weeks that have passed

They want to use the equation to estimate when the height of the plant will be 10
Amalia's estimate is after 6 weeks.
Alec's estimate is after Week 15.
Is either student correct?
Amalia would be correct. They are guessing when the height would be 10, and you are given an equation that will 'predict' that. Height is y, so substitute 10 in the equation and solve for x. You will get x=6

A hockey season ticket holder pays $88.56 for her tickets plus $5.00 for a program each game. A second person pays $19.76 for a ticket to every game, but doesn't buy programs. In how many games will they have paid the same amount?
Answer: x = 6
Step-by-step explanation: If you take 88.56 + 5x = 19.76x, an equation, you should first rearrange the variables to the left side of the equation: 5x - 19.76x = -88.56.
Next, you should combine your like terms. So, -14.76 = -88.56.
Then, divide both sides of the equation by the coefficient of variable. So, x = -88.56 / -14.76./
Lastly, calculate. Determine the sign for multiplication or division, so x = 88.56 / 14.76. Multiply both the numerator and denominator with the same integer. So, x = 8856 / 1476. Cross out the common factor, then you get your answer of x = 6

Two balls are drawn without replacement from a box containing 2black and 3 red balls. What is the probability of drawing a black ball on the second draw? Draw a tree diagram
The probability that the second ball drawn is black is 4/10 = 2/5
How to find the probability?
There are two cases. The case where the first ball is red is the first one.
The probability of drawing a red ball is equal to the quotient between the number of red balls and the total number of balls.
p = 3/5
Then, the probability of drawing a black ball in the second attempt is computed in the same way, but because we already drew a ball, now the total number of balls is 4, so we have:
q = 2/4 = 1/2.
So the joint probability is:
P = (3/5)*(1/2) = 3/10.
Then we have the case where both balls are black, the probabilities now are:
p = 2/5
q = 1/4
So the joint probability is:
P = (2/5)*(1/4) = 1/10
The total probability is the sum of the two above:
probability = 3/10 + 1/10 = 4/10.
The probability that the second ball drawn is black is 4/10 = 2/5
