Orlando is mixing nuts and cereal squares to make a party mix. Nuts sell for $7 a pound and cereal squares sell for $4 a pound. If Orlando wants to make 30 pounds of party mix at a cost of $6.50 a pound, how many pounds of nuts and how many pounds of cereal squares should he use?
Answer:
0.5lb cereal squares, 0.75 lb nuts
Step-by-step explanation:
1lb nuts = $7
multiply each side by 1/2 (whatever you do to one side, you do to the other),
0.5lb nuts = $3.5
1lb cereal squares = $4
multiply each side by 3/4 (whatever you do to one side, you do to the other),
0.75lb cereal squares = $3
0.5lb nuts + 0.75lb cereal squares = 3.5 + 3 = $6.5

On an exam, Mafuyu scored in the 20th percentile. If there were 50 students in the class, how many students scored lower than he did?
Using the percentile concept, it is found that 10 students scored lower than he did.
What is the meaning of the percentile of a measure?When a measure is in the xth percentile of a data-set, it is greater than x% of the measures and lesser than (100 - x)%.
In this problem, he scored on the 20th percentile, that is, higher than 20% of the 50 students. Then:
0.2 x 50 = 10.

find the coordinates of the point where the line [tex]y=5x+7\\[/tex] crosses the [tex]y[/tex] axis
Answer:
(0, 7)
Step-by-step explanation:
The point that crosses the y-axis is called the y-intercept of the line.
We are given an equation of the line and we need to determine the y-intercept. This can be done by determining the constant in the equation.
What are constants?
Constants are such terms that include only numbers. There should be no variables in constants.
We know that:
[tex]\bullet \ \text{Given equation of line: y = 5x + 7}[/tex]
The constant we can see in the equation is "7". Therefore, the y-intercept is 7.
Note: The y-intercept of the line must have an x-coordinate of 0.
Therefore,
⇒ Coordinates of y-intercept: (x, y) ==> (0, 7).

If you flip 11 coins, the probability of not getting all 11 tails is
The required probability of not getting all tails is 2037 / 2048.
Given that,
If you flip 11 coins, the probability of not getting all 11 tails is to be determined.
What is probability?
Probability can be defined as the ratio of favorable outcomes to the total number of events.
What is simplification?The process in mathematics to operate and interpret the function to make function simple or more understandable called simplify and the process is called simplification.
Since each coin has 2 possible outcomes for a single toss i.e either head or tail.
Total number of sample spaces for the 11 coins to be tossed = 2^11 = 2048
The number of favorable outcomes for all tails = 11
Probability of not getting all 11 tails = 1 - probability of all are tails
= 1 - 11 / 2048
= 2037 / 2048
Thus, the required probability of not getting all tails is 2037 / 2048.

The following histogram shows the number of days during the school year that students bought lunch.
a. How many total students are at the school?
b. What is the probability that a randomly chosen student will by lunch between 10 and 20 times in a month?
The total number of students is 470.
The probability that a randomly chosen student will by lunch between 10 and 20 times in a month is 0.26.
What is the total number of students?
A histogram is used to represent data graphically. the histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval.
The total number of students = 140 + 120 + 80 + 40 + 30 + 60 = 470
What is the probability?The probability that a randomly chosen student will by lunch between 10 and 20 times in a month = number of students between 10 and 20 times / total number of students
(80 + 40) / 470 = 0.26

Applying the triangle proportionality theorem, the length of Jk in the diagram given is: 16 units.
What is the Triangle Proportionality Theorem?The triangle proportionality theorem states that when a side of a triangle is parallel to a line that intersects the other two sides of the triangle, then it divides the two sides of the triangle, proportionately.
Using the triangle proportionality theorem, we have the ratio if JK is x:
x/(36 - x) = (63 - 35)/35
x/(36 - x) = 28/35
35x = 28(36 - x)
35x = 1,008 - 28x
35x + 28x = 1,008
63x = 1,008
x = 16

Which triangle could be drawn as it is described ?
Answer: D
Step-by-step explanation:
Step-by-step explanation:
The side measures of choices A and C do not form a triangle of any sort.
The angle measures of choice B mean the remaining angle is ...
180° -110° -35° = 35°
Two of the angles are the same measure, so the triangle will be isosceles, not scalene. No scalene triangle can be formed with those angle measures.
__
The angle measures of choice D mean the remaining angle is ...
180° -20° -80° = 80°
Two of the angles are the same measure, so an isosceles triangle can be formed as described in choice D.

If 60 kilovolts was used for a radiographic exposure and a 15 % increase is required, which of the following should be set by the technologist?
Step-by-step explanation:
there is nothing "following" here.
however, if I understand correctly, we need a 15% increase to 60 kV.
100% = 60 kV
1% = 100%/100 = 60/100 = 0.6 kV
15% = 1% × 15 = 0.6 × 15 = 9 kV
so, adding these 15% gives us
60 + 9 = 69 kV.
once we understand this mechanism, we can also use the shortcut : to add x% to something, we need to multiply this something by 1.x.
in our case, we want to increase 60kV by 15% ?
the result is
60 × 1.15 = 69 kV
simply because (as the top part should have shown too) x% of the whole = x/100 × whole.
so, to add x% means to have
100/100 × whole + x/100 × whole = 1.x × whole

a helicopter took 39 minutes to fly 91 miles, traveling in a headwind. the same helicopter took one hour and 15 minutes to fly 195 miles flying in the opposite direction. if the wind speed and direction was the same for both flights, find the speed of the helicopter in still air and the wind speed. gina wilson algebra brainly
Using the relation between velocity, distance and time, it is found that the velocity of the helicopter is of 225 mph and of the wind is of 69 mph.
What is the relation between velocity, distance and time?Velocity is given by distance divided by time, that is:
[tex]v = \frac{d}{t}[/tex]
A helicopter took 39 minutes to fly 191 miles, traveling in a headwind. Due to the headwind, the relative velocity is the sum of the velocities, hence:
[tex]v_h + v_w = \frac{191}{\frac{39}{60}}[/tex]
[tex]v_h + v_w = 294[/tex]
[tex]v_w = 294 - v_h[/tex]
The same helicopter took one hour and 15 minutes to fly 195 miles flying in the opposite direction, hence:
[tex]v_h - v_w = \frac{195}{\frac{75}{60}}[/tex]
[tex]v_h - v_w = 156[/tex]
Since [tex]v_w = 294 - v_h[/tex]:
[tex]v_h - 294 + v_h = 156[/tex]
[tex]2v_h = 450[/tex]
[tex]v_h = 225[/tex]
[tex]v_w = 294 - 225 = 69[/tex]

Step-by-step explanation:
Find the value of x.
Answer:
x=21
Step-by-step explanation:
Following the vertical angles, we can assume that the equation that has x and 87 are equal to each other. From then, you set them equal to each other and solve for x.
87=4x+3
84=4x subtract 3 from both sides
21=x divide by 4 to get the x alone on both sides
