One serving of yogurt has 95 cal what is a reasonable estimate for the number of calories in 2.5 servings of yogurt One serving of yogurt has 95 cal what is a reasonable estimate for the number of calories in 2.5 servings of yogurt
Answer:
2.5 servings have 237.5 calories.Step-by-step explanation:
To solve this problem we need to apply the rule of three.
If one serving has 95 calories, then how much calories would have 2.5 servings?
[tex]2.5 \ servings \ \frac{95 \ calories}{1 \ serving}=237.5 \ calories[/tex]
Therefore, 2.5 servings have 237.5 calories.
A coffee merchant wants to make 6 pounds of a blend of coffee costing five dollars per pound. The blend is made using a six dollar per pound grade coffee and a three dollar per pound grade of coffee. How many pounds of each of these grades should be used?
Answer:
We should use 4 pounds of $6 coffee and 2 pounds of $3 coffee for the blend.
Step-by-step explanation:
The blend should,
Cost = $5
Weigh = 6 pounds.
Lets take the weight of $6 coffee as [tex]x[/tex] pounds
And lets take the weight of $3 coffee as [tex]y[/tex] pounds.
Lets write an equation for the weight of the blend,
[tex]x+y=6[/tex] <---------- 1st equation.
[tex]\frac{6x+3y}{x+y} =5[/tex]
=[tex]6x+3y=5x+5y[/tex]
=[tex]x=2y[/tex] <---------- 2nd equation
We can substitute to x in 1st equation from 2nd equation,
⇒[tex]2y+y=6[/tex]
=[tex]2y+y=6[/tex]
=[tex]3y=6[/tex]
=[tex]y=2[/tex]
We can substitute y value to 2nd equation to find x,
⇒[tex]x=2y[/tex]
=[tex]x=2*2[/tex]=[tex]x=4[/tex]
Therefore, we should use 4 pounds of $6 coffee and 2 pounds of $3 coffee for the blend.

Line JK has the slope 3/4 and is perpendicular to line LM. What is the slope of line LM?
Answer:
The slope of line [tex]LM[/tex] is [tex]-\frac{4}{3}[/tex]
Step-by-step explanation:
Line [tex]JK[/tex] has the slope [tex]\frac{3}{4}[/tex] and is perpendicular to line [tex]LM[/tex]
Suppose, the slope of line [tex]LM[/tex] is [tex]m[/tex]
We know that, the product of the slopes of two lines which are perpendicular to each other is always [tex]-1[/tex]. So, the equation will be..............
[tex]\frac{3}{4}*m= -1\\ \\\frac{3m}{4}=-1\\ \\ 3m= -4\\ \\ m=-\frac{4}{3}[/tex]
So, the slope of line [tex]LM[/tex] will be [tex]-\frac{4}{3}[/tex]

Which statement best explains who earns the most money per item sold
Since you didn’t include the statements, the answer is Marsha.
Why? Her slope increases more per item sold than Dreya.
[tex]\text{The slope formula is: }y=mx+b[/tex]
Marsha earns the most money per item sold because her profit margin is higher, and her earnings increase more rapidly as she sells more items compared to Dreya. Correct option is 2.
Marsha earns the most money per item sold because her profit margin per unit is higher than Dreya's. Profit margin is calculated by subtracting the cost of producing or acquiring an item from its selling price and then dividing the result by the selling price. If Marsha's profit margin per item is larger than Dreya's, it means that she earns more money for each item sold.
The statement also mentions that Marsha's slope increases more per item sold than Dreya's. This likely refers to a graphical representation where Marsha's revenue or profit line has a steeper slope than Dreya's. A steeper slope indicates that Marsha's earnings increase at a faster rate for each additional item sold, reinforcing the idea that she earns more money per item.

What is the value of f? 6f − 12 = −4f + 6
A. −9
B. −3/5
C. 1 4/5
D. 9
The answer is D! Aight hope it helped
The value of f in the equation 6f − 12 = −4f + 6 is 1 4/5.
Explanation:To answer the student's question, we need to solve the algebraic equation 6f − 12 = −4f + 6 for the unknown variable f. First, we want to get all terms with f on one side of the equation, and all constant terms on the other side. Thus, we'll add 4f to each side of the equation to eliminate -4f from the right side of the equation and get 6f + 4f = 6 + 12. This simplifies to 10f = 18, then we divide each side by 10, and we get f = 18/10 which reduces to f = 1 4/5 (Option C).

What is the value of x ?
Remark
The 2 angles are vertically opposite and that means they are equal.
Equation
(3x - 3) = [6(x - 10)]
Solution
Remove the brackets.
3x - 3 = 6(x - 10)
3x - 3 = 6x - 60 Subtract 3x from both sides
- 3 = 6x - 60 - 3x Combine like terms
-3 = 3x - 60 Add 60 to both sides
-3 + 60 = 3x
57 = 3x Divide by 3
57 / 3 = 3x / 3

A restaurant has 1,996 forks, 1,745 knives and 2,116 spoons. The owner wants to have 2,000 of each utensil. She can buy more utensils or donate extra utensils. How many additional forks and knives are need? How many extra spoons are there?
Answer:
4 forks and 255 knives will be needed more, while 116 spoons are extra.
Step-by-step explanation:
A restaurant has 1996 forks, 1745 knives and 2116 spoons.
Owner wants to have 2000 of each utensil.
So make them equal to 2000, number of forks needed = 2000 - 1996 = 4
[Subtracted from 2000 because number of forks are less than 2000]
Number of knives needed = 2000 - 1745
= 255
[Again subtracted from 2000 because number of knives are less]
Number of spoons to be donated = 2116 - 2000
= 116
[2000 is subtracted from total number of spoons because spoons are more than 2000]
Therefore, 4 forks and 255 knives will be needed more, while 116 spoons are extra.
100e^0.125t=200
A. t= ln(16)
B. t= ln(256)
C. t= 8ln(100)
D. t= 0.08ln(200)
To solve the equation 100e^0.125t=200 for t, divide by 100, apply the natural logarithm, and rearrange to find t=ln(2)/0.125, which simplifies to t=ln(16).The Correct Answer is Option. A.
Explanation:The question involves solving for the variable t in the exponential equation 100e^0.125t=200.
To solve this, we need to isolate the exponent on one side. Here are the steps to find the correct value of t:
Divide both sides by 100 to get e^0.125t = 2.Apply the natural logarithm (ln) to both sides to obtain ln(e^0.125t) = ln(2).Simplify the left side using the property ln(e^x) = x, resulting in 0.125t = ln(2).Finally, divide both sides by 0.125 to find t. This gives t = ln(2)/0.125.The correct answer from the given options is A. t= ln(16), as ln(2) / 0.125 = ln(16).

Shane and Karen want to measure the length of a soccer field. Should they use centimeters or meters to measure it. Explain
Hello!
They should most definitely use meters. Meters are much bigger than centimeters as centimeters are 1/100th of a meter. Meaning, it will take 100 centimeters to get 1 meter. A soccer field is a large surface, and to get a simpler number, you should use meters.

5 decimal jumps to the right is a shortcut to what math
In this Decimal Point Movement question, Moving the decimal five places to the right in mathematics is a shortcut for multiplication by 105 (one hundred thousand). This uses the principle of powers of ten.
In mathematics, moving the decimal five places to the right is actually a shortcut for multiplying by 105, or 100,000. This concept utilizes the patterns in powers of ten. For instance, for any given number, we can count the zeros in the power of ten and then move the decimal point that same number of places to the right.
Illustrating with an example, let's say we have the number 5.27. If we multiply it by 105, we move the decimal five places to the right to get 527000. This aligns with the multiplication principle: when we multiply by 10, 100, 1000, and so on, each time, we are essentially incrementing the decimal place to the right.
