Answer:
m< MPQ = 76degrees
Explanation:
From the digaram shown;
arcMNQ + arc MPQ = 360 degrees
Given that
arcMNQ = 208degrees
arc MPQ = 360 - arcMNQ
arcMPQ = 360 - 208
arcMPQ = 152degrees
The length of arc MPQ is 152degrees
m< MPQ = 152/2
m< MPQ = 76degrees

A calf raiser mixes a batch of milk replacer for 15 calves. Each calf gets two
quarts of milk replacer. If the calf raiser uses 960 oz. of replacer and needs to
add 34 as much water as milk replacer, how many ounces of water does she need?
Answer:
The calf raiser uses 960 oz of milk replacer for 15 calves, so each calf gets 960 oz / 15 = 64 oz of milk replacer.
To convert this to quarts, we need to divide by 32 (since there are 32 oz in a quart)
64 oz / 32 oz/quart = 2 quarts
Each calf gets 2 quarts of milk replacer and the calf raiser needs to add 34 as much water as milk replacer
So the total amount of water she needs is 2*34 = 68 quarts
To convert the quarts of water to ounces we need to multiply by 32 (since there are 32 oz in a quart)
68 quarts * 32 oz/quart = 2176 oz of water.
So the calf raiser needs 2176 ounces of water to mix with the milk replacer for 15 calves.

What is the sec 132 degrees 15 minutes in degrees
The sec 132 degrees 15 minutes in degrees is approximately -1.638 degrees.
What is the sec function?The secant function, denoted as sec(x), is a trigonometric function that is defined as the reciprocal of the cosine function, cos(x).
In other words,
sec(x) = 1 / cos(x)
The secant function is defined for all values of x except for those where the cosine function is equal to zero, which corresponds to the values x = (2n+1)π/2 where n is an integer. At these points, the secant function is undefined.
According to the given informationTo convert sec(132 degrees 15 minutes) to degrees, we first need to convert the angle to decimal degrees.
We know that 1 degree is equal to 60 minutes, so 15 minutes is equal to 15/60 = 0.25 degrees.
Therefore, the angle 132 degrees 15 minutes is equal to 132 + 0.25 = 132.25 degrees.
Now we can find the secant of this angle:
sec(132.25 degrees) = 1/cos(132.25 degrees) ≈ -1.638
So the answer is approximately -1.638 degrees.

9514 1404 393
Answer:
17 singles24 doubles11 triplesStep-by-step explanation:
Let s, d, t represent the numbers of singe, double, and triple cones sold. The problem statement tells us three relationships.
s + d + t = 52 . . . . . . Danielle sold 52 cones one day
d -2t = 2 . . . . . . . doubles is 2 more than twice the number of triples
0.89s +1.19d +1.39t = 58.98 . . . . total amount of sales
__
There are many ways to solve this set of equations. A graphing calculator can quickly tell you the solution is ...
(s, d, t) = (17, 24, 11)
__
If you want to solve this by hand, it may work well to use substitution.
The second equation gives an expression for d:
d = 2t +2
The first equation gives an expression for s that can be written in terms of t.
s = 52 -d -t
s = 52 -(2t +2) -t = 50 -3t
Using these in the last equation, we have ...
0.89(50 -3t) +1.19(2t +2) +1.39t = 58.98
1.10t = 12.10 . . . . . . . . collect terms, subtract 46.88
t = 11 . . . . . . . . . . . . . . divide by 1.10
d = 2(11) +2 = 24
s = 50 -3(11) = 17
Danielle sold 17 singles, 24 doubles, and 11 triple cones.

Kiara sets up a passcode on her tablet, which allows only 7 digit codes. she has heard that it’s more secure if a digit is repeated in the passcode. A spy sneaks a look at Kiara’s tablet and sees her fingerprints on the screen over 6 numbers. what is the probability the spy is able to unlock the tablet on his first try? express your answer as a fraction
Lets suppose that the numbers that the spy saw were 1,2,3,4,5,6 and by the question we know that the password has 7 digits, meaning that one of those number repets itself. We dont know wich one repets, so we need to keep that in mind. First, lets imagine that the number 1 repeats, so one of the possibilities is:
\(1123456\)We can see that to find all the possibilities of passwords with 1 repeating is a permutation with repetition. So the amount of passwords that we can have is:
\(\text{Passwords with 1 repeating=}\frac{7!}{2!}=7\times6\times5\times4\times3=2520\)Now, we just need to calculate the possibilities when 2,3,4,5 or 6 repeats:
\(\text{Passwords with 2 repeating=}\frac{7!}{2!}=7\times6\times5\times4\times3=2520\)\(\text{Passwords with 3 repeating=}\frac{7!}{2!}=7\times6\times5\times4\times3=2520\)\(\text{Passwords with 4 repeating=}\frac{7!}{2!}=7\times6\times5\times4\times3=2520\)\(\text{Passwords with 5 repeating=}\frac{7!}{2!}=7\times6\times5\times4\times3=2520\)\(\text{Passwords with 6 repeating=}\frac{7!}{2!}=7\times6\times5\times4\times3=2520\)So, in total we have 15120 possibilities of passwords, so the probability of a spy getting the password first try is:

Step-by-step explanation:
one card is drawn from a pack of 52cards each of the 52 cards being equally likely to be drawn. what is the probability that the card drawn is a king?
The probability of drawing a king from a standard deck of 52 cards is 1/13.
In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.
To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).
The total number of possible outcomes is 52 because there are 52 cards in the deck.
The favorable outcomes, in this case, are the four kings.
Therefore, the probability of drawing a king is given by:
Probability = (Number of favorable outcomes) / (Number of possible outcomes)
= 4 / 52
= 1 / 13
Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.
This means that out of every 13 cards drawn, on average, one of them will be a king.
It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.
Each draw is independent, and the probability of drawing a king is constant.

Ellie bought a scarf and a dress The scarf cost £4 She sold both items for £26 She made 100% profit on the scarf 30% profit on the total cost Work out her percentage profit on the cost of the dress
Answer:
Step-by-step explanation:
hold I’m going to put much elaborated steps in the comments
Answer and Step-by-step explanation:
Let's first calculate the cost of the dress.
If Ellie made a 100% profit on the scarf, that means she sold it for twice the cost, or £8. So, the cost of the scarf was £4.
To find the cost of both items, we can subtract the cost of the scarf from the total price:
Total price = £26
Cost of scarf = £4
Cost of dress = £26 - £4 = £22
Ellie made a 30% profit on the total cost, which includes the cost of both the scarf and the dress.
To calculate the total profit, we can find 30% of the total cost:
30% of £26 = 0.3 x £26 = £7.80
So, Ellie's total profit is £7.80.
To find the percentage profit on the cost of the dress, we need to compare the profit made on the dress to its cost.
Profit on the dress = Total profit - Profit on the scarf
Profit on the dress = £7.80 - £4 = £3.80
So, Ellie made a profit of £3.80 on the dress.
To calculate the percentage profit on the cost of the dress, we can divide the profit by the cost and then multiply by 100 to get a percentage:
Percentage profit on the dress = (Profit on the dress / Cost of dress) x 100%
Percentage profit on the dress = (£3.80 / £22) x 100%
Percentage profit on the dress ≈ 17.27%
Therefore, Ellie made a percentage profit of approximately 17.27% on the cost of the dress.
