====================================================
Work Shown:
(2.50 dollars)/(8 juice boxes) = (x dollars)/(24 juice boxes)
2.50/8 = x/24
2.50*24 = 8x
60 = 8x
8x = 60
x = 60/8
x = 7.50
----------------
Another approach:
She paid $2.50 for 8 juice boxes. The unit price is 2.50/8 = 0.3125 dollars per juice box. Multiply this by 24 to get 24*0.3125 = 7.50
----------------
Yet another method:
We know the cost for 8 juice boxes is $2.50
We want to know the cost for 24 juice boxes.
The jump from 8 to 24 is "times 3". So we'll multiply the $2.50 cost by 3 to get 3*2.50 = 7.50
We can think of it like this
[tex]\frac{2.50 \ \text{dollars}}{8 \ \text{juice boxes}}=\frac{3*2.50 \ \text{dollars}}{3*8 \ \text{juice boxes}}=\frac{7.50 \ \text{dollars}}{24 \ \text{juice boxes}}[/tex]

Help ASAP solve for the value of Z
Answer:
z = 6
Step-by-step explanation:
The angle in the middle is a right angle with a measure of 90°
Together, all three angles, makes a stright angle which is measured 180°.
So we can write the following equation to find the value of z:
5z + 1 + 59 = 90 (we don'thave to include the middle angle since we already its measure)
add like terms
5z + 60 = 90 subtract 60 from both sides
5z = 30 divide both sides by 5
z = 6

find the area under the standard normal curve between z=0 and z=3
The area under the standard normal curve between z=0 and z=3 is 0.4987.
How to illustrate the information?It should be noted that because the normal distribution is symmetrical on both sides of the mean and is a continuous probability distribution, the right side of the center is the opposite of the left side.
The normal distribution was first termed by early statisticians who observed that the same shape repeatedly appeared in many distributions. The characteristics of normal distributions are as follows: Bell-like in its symmetry. The distribution's mean and median, which are both at its center, are equal.
The area will be illustrated as:
P(0 < Z < 3)

A house purchased for $265,100 gains 2% of its value every year. If this growth rate continues, in how many years will the house be worth twice its original value
The price of the house will double the original value in 35 years
How to determine the number of years?The given parameters from the question are
Initial value of the house = $265,100
Rate of gain = 2% of its value every year
An exponential function is represented as
y = a *(1 + r)^x
Where
y represents the current valuea represents the initial valuer represents the growth or decay ratex represents the number of years, in this caseThis means that
a = 265,100
r = 2%
So, we have
y = 265,100 *(1 +2%)^t
When the price doubles, we have
2 * 265,100 = 265,100 *(1 +2%)^t
Divide both sides by 265,100
So, we have
2 = (1 +2%)^t
Evaluate the sum
So, we have
2 = 1.02^t
Take the logarithm of both sides
t * log(1.02) = log(2)
Divide
t = log(2)/log(1.02)
Evaluate
t = 35
Hence, the number of years is 35

The graph shows the temperature of a liquid that is being heated during an experiment. Three of the statements are true. Which is NOT?
The statement that is not true is that at this rate, it would take less than 10 mins for the temperature of the liquid to rise to 52 degrees.
Which statement is not true?We know that in a graph we see the presentation of a data set by the use of the Cartesian coordinates. There is the vertical axis and there is the horizontal axis. The vertical axis is the axis where we have to plot the time while the vertical axis is the axis where we have to plot the temperature as we can see from the image attached to this answer.
The graph as show has to the points which are; (0, 0) and (6.5, 26). Thus we can use the both points to obtain the slope of the graph and this would give us;
m = 26 - 0/ 6.5 - 0
m = 4
This implies that the rate at which the temperature rise with time is 4 degrees centigrade per hour. In a quarter hour, the temperature would rise to;
y = mx

Answer:
i cannot see the lines very well, but i can tell you how to find slope
Step-by-step explanation:
slope is rise/run. find where the line hits a intersection on the graph, and count the squares across the graph where it hits another intersection. it should not be on the line though, because that is only the run. then count how many squares up it takes till you touch where the line hits another intersection. that is the rise. then divide the rise by the run.

The animals at a safari park include gorillas, buffalo and wallabies. There are 24 more buffalo than there are gorillas. There are 7 times as many wallabies as there are gorillas. There are the same number of buffalo as there are wallabies. How many gorillas are there at the safari park?
The number of gorillas at the safari park is 4.
Let the number of gorillas at the safari park be x.
It is given that there are 24 more buffalo than there are gorillas.
Number of buffalo at the safari park = 24 + x
There are 7 times as many wallabies as there are gorillas.
Number of wallabies at the safari park = 7x
Now, the number of buffalo is the same as the number of wallabies.
So, we equate their numbers to find the value of x i.e. number of gorillas.
24 + x = 7x
7x - x = 24
6x = 24
x = 4
Therefore, the number of gorillas at the safari park is 4.
