Answer:
(X,Y)=( [tex]\frac{4}{3}[/tex] ,[tex]\frac{25}{9}[/tex])
Step-by-step explanation:
Answer:
x = 1 1/3 and y = 2 7/9
Step-by-step explanation:
Subtract the two equations:
[tex]5x + 3y = 15\\2x + 3y = 11[/tex]
3x = 4
divide both sides by 3
x = 4/3
Substitute this into the equation 5x + 3y = 15
[tex]5(\frac{4}{3} ) + 3y = 15\\\frac{20}{3} + 3y = 15\\3y = 8\frac{1}{3} \\y = 2\frac{7}{9}[/tex]

Answer the following questions using the graph at the right (attatched). The graph shows the height h in feet of a snowball t seconds after it is launched. The path of the snowball is given by the equation: h = -16t^2 + 128t
How long is the snowball in the air? Explain how you know the answer based on the graph
Answer:
8secs
Step-by-step explanation:
To calculate how long the ball stays in air, we need to find the time it takes to reach the max height first
The ball reaches its max height when dh/dt = 0.
-32t+128=0
32t = 128
t = 128/32
t = 4secs
The time the ball spent in air will be;
t = 2(4)
t = 8secs
Hence the ball spent 8secs in air

Salma will run less than 35 miles this week. So far, she has run 18 miles. What are the possible numbers of additional miles she will run?
Use t for the number of additional miles she will run.
Write your answer as an inequality solved for t.
Answer:
We know that Salma will run less than 35 miles in total this week.
So if t represents the number of miles that Salma runs, we have the inequality:
0mi ≤ t < 35 mi
(where the first part comes because she can not run a number of negative miles, but this is trivial.)
We know that she already ran 18 miles, then we have now the inequality:
t + 18mi < 35mi
Now we need to isolate S
t < 35mi - 18mi
t < 17mi
So she can run any number of miles that is smaller than 17 miles.
For example, she could run 10 miles, 14 miles, 4.5 miles, etc.

Step-by-step explanation:
A quality assurance inspector at a donut factory, checks for product quality using a random sample of 7 donuts from a batch of 38, with 14 cake donuts and 24 glazed donuts. Let p^ be the proportion of cake donuts in the sample.
Is the 10% condition met in this case?
Is the Normal condition met in this case?
Answer:
No/maybe and Yes
Step-by-step explanation:
A) The normal condition states that the population must be greater than or equal to 10n. In this case 10 * 7 (sample size) = 70 which is greater than the batch of 38. You could argue that the factory is likely to produce more than 38 donuts, so it may be possible for Samuel to meet the 10% condition if he is talking about more than one batch.
B) The normal condition is met by np [tex]\geq[/tex] 10 and n(1-p) [tex]\geq[/tex] 10.
We already know that the sample size is 7, so all we need to do is find p. Except we don't. The value of p represents probability, and something can not occur more than 100% of the times that it is possible. For this reason p can only be 0 - 1.0. Even at 100% probability, 7 * 1 < 10, so the normal condition can never be met with only 7 samples.

ALGEBRA: Sandra Woo delivers flowers. She earns $5.50 to deliver a small arrangement and $8.25 to deliver a large arrangement. Last week she made 52 deliveries and earned a total of $343.75. How many LARGE arrangements did she deliver?
Answer:
the large arrangement be 21
Step-by-step explanation:
The computation of the large arrangements she delivered is as follows:
Let us assume the small arrangement be x
And, the large arrangement be y
Now as per the question
5.50x + 8.25y = $343.75 ......(1)
x + y = 52........(2)
We can write as
x = 52 - y
Now put the x value in the (1) equation
5.50(52 - y) + 8.25y = $343.75
$286 - 5.50y + 8.25y = $343.75
2.75y = 57.75
y = 21
Hence, the large arrangement be 21
Write the equation of a line that is perpendicular to the line y = x – 5 and contains the
point (-4, 13)?
Answer:
y = -x + 9
Step-by-step explanation:
Here, we want to write the equation of a line
mathematically, if two lines are perpendicular, the product of their slopes is -1
Comparing the given equation with the general form of;
y = mx + b
where m is the slope and b is the y-intercept, we can see that the slope value is 1
So the slope of the second line will be;
-1/1 = -1
now we want to write the equation of a line that has a slope of -1 and passes through the point (-4, 13)
we use the point-slope form here
That will be;
y-y1 = m(x-x1)
y-13 = -1(x+ 4)
y-13 = -x - 4
y = -x -4 + 13
y = -x + 9

Answer:90%
i used my calculator but basically i added the numbers up and divided them by 75 which gave me 10% so that is the percent of the oranges so you substracted by the whole (100%) and it gives you the answer, your welcome.
The 90% of the fruit is apples.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Jamal has 75 oranges and 675 apples.
The total fruits are 750.
Let n be the percentage of the fruit is apples.
So,
675 = n x 750/100
n = 67500/750
n = 90%

(-4t^5) (-10t) NEED AN ANSWER VERY SOON !! PLEASE HELP!!!!
Answer:
40t⁶
Step-by-step explanation:
Since -4t⁵ and -10t have the same variable (base), we can multiply their coefficients (numbers) and add their exponents
-4t⁵ * -10t = 40t⁶
Since both numbers are negative, when we multiply them, they cancel out.
SInce both variables are the same (both are t), we can just add their exponents together. Even though we don't see an exponent above -10t, we can assume that it is 1. Think of it as this, -10t = -10t¹ because it just represents -10t, -10t (specifically the t) isn't being multiplied by anything.
Answer:
40t^6
Step-by-step explanation:
(-4t^5)(-10t) = 4t^5 • 10t
40t^5 t = 40t^ 5+1 = 40t^6
