Answer:
C
Step-by-step explanation:
If we round up the 3/4 cup of sugar to 1 cup to make it easier, and then multiply by 2 because the 3/4 cup of sugar only makes half a dozen cupcakes, then we will get 2 cups of sugar which is an overestimate of how much is needed. If we multiply it again by 3 because he needs 3 times the amount of sugar, we get 6 cups of sugar because we rounded it up. Since we know 3/4 is less than 1, we can assume that 6 cups of sugar is more than needed.

Quandrilateral ABCD is inscribed in a circle. What is the measure of angle A? A=(2x-40)B 116 C D=x what is the measure of angle A
Answer:
angle A = 88°
Step-by-step explanation:
Given: inscribed quadrilateral ABCD
(recall that inscribed quadrilaterals have opposite angles supplementary.
A=2x-40
B=116
D=x
From inscribed quadrilateral,
B+D=180 => 116+x = 180 => x=64
A=(2x-40) = 2*64-40 = 88°
(C = 180-88 = 92°)

What is the area please
The answer is 105 units²
Explanation:
Since the middle is a square, the base of all 4 triangles are equal.
Let x be the height of the triangles.
The height of the triangle can be defined as:
15 = 7 + x + x
15 = 7 + 2x
15 - 7 = 2x
x = 8/2
x = 4
Area = area of square + 4(area of triangle)
= (7 x 7) + 4(1/2(7)(4))
= 49 + 56
= 105 units²

what is x in this problem 8-(-4)^2-5=x
Answer:
X=-12
Step-by-step explanation:
9-16-5=X
-12=X
X=-12
Answer:
-13
Step-by-step explanation:
This is just a matter of simplifying.
x = 8-(-4)^2-5
Let's get rid of the exponent.
x = 8 - 16 - 5
x = -13
You can check if this is correct.
The tricky part is the -(-4)^2.
You have to solve the -4^2 first, instead of the parenthesis.

A golfer strikes a golf ball into the air from the ground. The height, h metres, of the ball
can be modelled by h = 32t – 4t2, where t is the time in seconds after it leaves the
ground.
i. On a sheet of graph paper, using a scale of 2 cm to represent 1 unit on the t -axis
and 1 cm to represent 5 units on the h -axis, draw the graph of h = 32t – 4t2
ii Use your graph to find he maximum height of the ball above the ground and the time
at which it occurs.
u dont have to draw the graph can u just find the values for me thanku
Answer:
64 m, at time t = 4 sec
Step-by-step explanation:
We must maximize the function h = 32t – 4t^2. One way in which to do this is to find the axis of symmetry, t = -b / [2a], and from that calculate the height:
a = -4, b = 32, c = 0
-32
and therefore the axis of symmetry is t = ---------------- = 4
2(-4)
The height, h, at time t = 4, is h(4) = 32(4) - 4(4)^2 = 64 m
The maximum height of the ball is 64 m, at time t = 4 sec
Step-by-step explanation:
The golf ball reaches its maximum vertical height when its vertical velocity h' becomes zero. Taking the derivative of h and setting it to zero, we get
h' = 32 - 8t = 0
which gives us t = 4 seconds. So after 4 seconds, the ball will reach its maximum height and its value is
h = 32(4) - 4(4)^2
= 128 - 64
= 64

Write the expression for 2 added to the product of a number p and 43
Answer:
43p + 2
Step-by-step explanation:
Product of p and 43 = 43p
2 added to the product of p and 43 = 43p + 2
Answer:
Step-by-step explanation:
The product of a number p and 43 means
p * 43 = 43p
And 2 added to the product gives;
43p + 2
However; the expression is 43p + 2.

According to a survey, about 30% of people ages 18 and older in a city have a cat. You ask 5 randomly chosen people (ages 18 and older) whether they have a cat. What is the probability that at least 2 people have a cat? Round your answer to the nearest hundredth.
Step-by-step explanation:
When they ask what the prob that at most 3/4 people asked have a pet, they are asking what is the prob that 0, 1, 2, or 3 people answer yes. So you could calculate all 4 of those and then add them together.
However, in this case, since there's only 1 other possible outcome (all 4 have a pet), we could just calculate the prob of that and subtract it from 1 to get the prob of everything else happening.
We'll use the binomial distribution formula where n=4, k=4, and P=.6.
nCk * P^n * (1-P)^(n-k)4C4 * (.6)^4 * (.4)^0.1296
So the prob of at least 3 having pets = 1 - P(all 4 have pets) which is 1-.1296 = .8704. You could double check this by calculating the prob of the other 4 outcomes and then adding them together.
The probability that at least 2 people have a cat is 0.522 or 52.2%.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
This is a problem that can be solved using the binomial probability formula, which gives the probability of getting exactly k successes (in this case, people with cats) out of n trials (in this case, people you ask) with a probability of success (in this case, having a cat) of p.
The formula is:
P(k) = (n choose k) × [tex]p^k \times (1-p)^{(n-k)}[/tex]
where (n choose k) is the binomial coefficient, which is equal to n! / (k! × (n-k)!).
For this problem, n = 5 (the number of people you ask), k = 2 (the number of people who have cats), and p = 0.3 (the probability of a person having a cat, according to the survey).
P(2) = (5 choose 2) × 0.3² × 0.7³
P(2) = 0.252
To find the probability of at least 2 people having a cat, we have to add up the probability of getting exactly 2, 3, 4, and 5 people having cats.
P(≥2) = P(2) + P(3) + P(4) + P(5)
Substituting the values we get:
P(≥2) = 0.252 + 0.189 + 0.072 + 0.009 = 0.522
So, the probability that at least 2 people have a cat is 0.522 or 52.2%.
