Answer:
600
Step-by-step explanation:
first you need to find the calories for the entire batter:
12 muffins x 250 cal = 3000 cal
then you divide the total calories by 20:
3000/20 = 150
then multiply 150 by 4:
150 x 4 = 600
To find the caloric content of each mini-muffin, divide the total calories in the recipe by the new yield to find that each mini muffin is 150 calories. Consuming 4 mini muffins will total 600 calories.
Explanation:The caloric content of a full-size muffin is 250 calories. If we reduce the size of the muffins we make from the recipe, it doesn't alter the total caloric content of the whole batch – it just redistributes those calories across more muffins. To calculate the number of calories in one mini-muffin, we need to divide the total number of calories in the entire recipe (250 calories/muffin * 12 muffins = 3000 calories) by the total yield of mini-muffins, which is 20. This results in 3000 calories/20 mini-muffins = 150 calories per mini-muffin. If you consume 4 mini-muffins, you'd be consuming 4 * 150 calories = 600 calories.

The answer for P(A∪B) is 40/45 (or) 8/9.
Step-by-step explanation:
Given,
The number of students that play only stringed instruments (A) = 35 students.
The number of students that play only brass instruments (B) = 10 students.
The number of students that play both of the instruments = 5 students.
The number of students that play none of the instruments = 5 students.
Probability = Number of required events / Total events
To find the total number of students,
TOTAL = A + B - both + neither.
TOTAL = 35 + 10 - 5 + 5 = 45 students.
P(A∪B) = P(A) + P(B) - P(A∩B)
Probability of A, P(A) = 35 students / 45 students = 35/45
Probability of B, P(B) = 10 students / 45 students = 10/45
Probability of A∩B (both), P(A∩B) = 5 students / 45 students = 5/45
P(A∪B) = (35/45) + (10/45) - (5/45)
= 40/45
P(A∪B) = 8/9

An engineer on the ground is looking at the top of a building. The angle of elevation to the top of a building is 38°. The engineer knows the building is 300 ft tall. What is the distance from the engineer to the base of the building to the nearest whole foot? ✓ 384 ft 487 ft X 234 ft 185 ft
Answer:
My best guess is 384 ft
Step-by-step explanation:
Tangent 38° = opposite side / adjacent side
Tangent 38° = 300 ft / x ft
The value of x from the equation is 383.98 ft. Thus, the engineer is 383.98 ft.
Rounding it up gives us 384 ft.
Answer:
384 ft.
Step-by-step explanation:
We know the opposite side of the triangle and we need the adjacent side.
So tan 38 = opposite / adjacent
= 300 / x
x = 300 tan 38
x = 383.98 feet.
Given Angle 1 = Angle 2,
find x.
Answer:
x = 6
Step-by-step explanation:
Given ∠ 1 = ∠ 2 then the segment is an angle bisector and the ratios of sides to base are equal, that is
[tex]\frac{3}{x-4}[/tex] = [tex]\frac{x}{4}[/tex] ( cross- multiply )
x(x - 4) = 12 ← distribute left side
x² - 4x = 12 ( subtract 12 from both sides )
x² - 4x - 12 = 0 ← in standard form
(x - 6)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 2 = 0 ⇒ x = - 2
However, x > 0 , thus x = 6
What is the x intercept and y intercept of this equation.
Answer:
x intercept is 15 and y intercept is -3.75
Step-by-step explanation:
The first thing is to form equation with the given tow point using the formula
y-y1/x - x1 = y2 - y1/ x2 - x1
y + 5/x + 5 = -2 + 5/7 + 5
y + 5/x + 5 = 3/ 12
3x + 15 = 12y + 60
12y - 3x = -45
On x intercept y = 0
x = 15
On y intercept x = 0
y = -3.75
explain how you know the numbers of the decimal places that should be in the product when you multiply two decimal numbers together
Answer:
0.214 * 0.32 = 0.06848 (3 + 2 = 5 decimal places)
0.7 * 0.11 = 0.077 (1 + 2 = 3 decimal places)
Step-by-step explanation:
Let's remember that multiplying decimals is the same as multiplying whole numbers except that you have to put the decimal point in the answer. When you multiply decimals, the decimal point is placed on the product so that the number of decimal places in the product is the sum of the decimal positions of the factors.
Example:
214 * 32 = 6,848
0.214 * 0.32 = 0.06848 (3 + 2 = 5 decimal places)
7 * 11 = 77
0.7 * 0.11 = 0.077 (1 + 2 = 3 decimal places)

For a company meeting, she spent $90 on to burrito platters and one taco platter. How much does each type of platter cost?
By setting up a system of equations from the given scenarios, we find that the cost of a burrito platter is $32 and the cost of a taco platter is $26.
Explanation:To solve Carmen's problem about the cost of burrito and taco platters, we need to set up a system of equations based on the information given.
We know she spent $58 on one burrito platter and one taco platter and $90 on two burrito platters and one taco platter.
Let's denote the cost of a burrito platter as B and the cost of a taco platter as T.
Step 1: Establish the Equations
The first scenario gives us the equation: B + T = 58.
The second scenario gives us the equation: 2B + T = 90.
Step 2: Solve the Equations
From the first equation, we can express T in terms of B: T = 58 - B.
Substitute the expression for T in the second equation: 2B + (58 - B) = 90.Simplify and solve for B: B = 32.Substitute the value of B back into any of the original equations to find T: T = 26.Therefore, the cost of a burrito platter is $32 and the cost of a taco platter is $26.

I need to solve by completing the square but I just can’t seem to get the correct answer, the quadratic is 2x^2- .5x-28=0
Answer:
x - 5.19 or x = -2.67 is the correct answer.
Step-by-step explanation:
Here, the given quadratic equation is: [tex]2x^2- 5x-28=0[/tex]
To solve it by : Completing The Square
Step : 1 Make the coefficient of leading variable x² as 1.
Divide whole equation by 2,we get:
[tex]x^2- \frac{5}{2} x-14=0\\\implies x^2- \frac{5}{2} x = 14[/tex]
Step 2: Find the coefficient of x in the equation and DIVIDE it by 2 to HALF THE VALUE
Here, the coefficient of x = (-5/2)
Dividing ot by 2, we get the value = (-5/4)
Step 3: ADD THE SQUARE of the found value on BOTH sides.
And USE: [tex](a - b)^2 = a^2 + b^2 - 2ab[/tex]
[tex]x^2- \frac{5}{2} x = 14 \implies x^2- \frac{5}{2} x + (\frac{5}{4} )^2= 14 + (\frac{5}{4} )^2\\\implies (x -\frac{5}{4})^2 = 14 + \frac{25}{16} = \frac{224 + 25}{16} = \frac{249}{16} \\\implies (x -\frac{5}{4})^2 = \frac{249}{16} = (\frac{15.7}{4})^2\\ \implies (x -\frac{5}{4})^2 = (\frac{15.7}{4})^2[/tex]
Step 4: TAKE ROOT ON BOTH SIDES, we get:
[tex](x -\frac{5}{4})^2 = (\frac{15.7}{4})^2\\\implies (x -\frac{5}{4}) = \pm (\frac{15.7}{4})\\\implies x = (\frac{15.7}{4}) +(\frac{5}{4}) = 5.19\\or, x = - (\frac{15.7}{4}) +(\frac{5}{4}) = -2.67\\[/tex]
So, either x - 5.19 or x = -2.67

Answer:Marissa walked [tex]\frac{65}{100}[/tex] miles altogether on saturday and sunday
Solution:Given that, Marissa walked her dog
From given information,
[tex]\text{Miles walked on saturday } = \frac{1}{10} \text{ mile }\\\\\text{Miles walked on sunday } = \frac{55}{100} \text{ mile }[/tex]
We have to find the distance walked in all
[tex]\text{Total distance } = \text{Miles walked on saturday + Miles walked on sunday }[/tex]
Substituting the values we get,
[tex]\text{Total distance } = \frac{1}{10} + \frac{55}{100}[/tex]
Make the denominators same for easier calculations by taking L.C.M of 10 and 100
Prime factors of 10 = 2 x 2 x 5
Prime factors of 100 = 2 x 2 x 5 x 5
For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.
The new superset list is

Multiply these factors together to find the LCM
LCM = 2 x 2 x 5 x 5 = 100
[tex]\text{Total distance } = \frac{1}{10} + \frac{55}{100}[/tex]
[tex]\text{Total distance } = \frac{1 \times 10}{10 \times 10} + \frac{55}{100}\\\\\text{Total distance } = \frac{10}{100} + \frac{55}{100}\\\\\text{Total distance } = \frac{10+55}{100} = \frac{65}{100}[/tex]

An expression that represents the total cost in dollars for two days for the n members of the club is given by .”
Answer:
[tex]x = \$187n[/tex]
Step-by-step explanation:
let x be the total cost in dollars for two days for the n members
Given:
The first day the members paid $70 for transportation plus $15 per ticket to the planetarium.
The second day they paid $90 for transportation plus $12 per ticket to the geology museum.
We need to write an an expression to represent the total cost in dollars for two days for the n members of the club.
Solution:
First day each member pay $70 for transportation and $15 for ticket,
[tex]Cost\ per\ member\ for\ the\ first\ day = transportation\ cost+ticket\ cost[/tex]
[tex]Cost\ per\ member\ for\ the\ first\ day = 70+15[/tex]
[tex]Cost\ per\ member\ for\ the\ first\ day = \$85[/tex]
Therefore, cost for n members for the first day.
[tex]Cost\ for\ n\ member\ for\ the\ first\ day = \$85n[/tex]
Similarly for the second day each member pay $90 for transportation and $12 for ticket,
[tex]Cost\ per\ member\ for\ the\ second\ day = transportation\ cost+ticket\ cost[/tex]
[tex]Cost\ per\ member\ for\ the\ second\ day = 90+12[/tex]
[tex]Cost\ per\ member\ for\ the\ second\ day = \$102[/tex]
Therefore, .
[tex]Cost\ for\ n\ member\ for\ the\ second\ day = \$102n[/tex]
Now, we write an expression to represent the total cost in dollars for two days for the n members of the club, so cost for n members for two days is equal to sum of the two days expenses for n members.
[tex]Cost\ for\ n\ member\ for\ the\ two\ day = \$85 + \$102n[/tex]
[tex]x = \$85n + \$102n[/tex]
[tex]x = \$187n[/tex]
Therefore, total cost for two days for the n members [tex]x = \$187n[/tex]
The table below shows selected points from a function.
Fist section box answer choice: Constant, not Constant
second section box answer choice: linear, non-linear
The rate change of interval for the given table is Constant , so the function a linear function.
Step-by-step explanation:
A linear function is defined as a function which yields a line in a graph and the rate of change(constant) is called as slope.
Since the rate is constant, then function will result in a straight line.
From the given table the slope m=1 and it changes constantly.
The linear equation formula is y=mx+c.
where m is the slope and c is the y-intercept.
The linear equation for the given table is y=x+1.
∴ The rate change of interval for the given table is Constant , so the function a linear function.
If the graph for a function has any shapes other than a straight line then it doesn't have a constant slope and it will be a non-linear function.
