Answer:
He is incorrect. He would need 225g of cocoa powder
Step-by-step explanation:
1. Lets calculate how much powder do we need per one cupcake, so 60 divided by 20, since 60g makes 20 cupcakes, 60/20 = we get 3g of cocoa powder per one cupcake.
2. Now we can multiply that by 75, 75*3=225, and 225g is more than 210g

Abby wants to ride her bicycle more than 70 miles this week. On Monday, Abby rode her bicycle for 25 miles. Abby plants to ride the same number of miles in the next six days. Write an inequality that can be used to determine the number of miles, m, that Abby will ride her bicycle each day to achieve her goal.
Answer:
25d > 70
Step-by-step explanation:
Abby wants to ride her bicycle more than 70 miles this week.
More than = >
On Monday, Abby rode her bicycle for 25 miles. Abby plants to ride the same number of miles in the next six days.
Let the number of days of week she would ride her bike = d
On Monday = 25 miles
And the rest of the week = The same = 25 miles
The inequality is written as:
25d > 70
A consultant for a major computer company receives $3250 per month as a fee no matter how many hours he works. Using x to represent the number of hours the consultant works each month, write a function, f, in symbolic form to represent the total amount the consultant recieves each month.
Answer:
The function is;
f(x) = $3,250
Step-by-step explanation:
The fixed amount the consultant receives each month = $3,250
The number of hours the consultant works each month = x
Let f(x) represent the function of the total amount the consultant receives each month
Therefore;
The function f(x) = The total amount the consultant receives each month = The fixed amount the consultant receives = $3,250
∴ f(x) = $3,250.
The function 'f' which represents the total amount the consultant receives each month is f(x) = $3,250 (Given that the consultant receives a constant amount each month).

Clara has 9 pounds of apples. She needs 1 1/4 pounds to make one apple pie. If she saves 2 pounds for applesauce, how many pies, p, can she make? Write an algebraic equation to represent this situation.
Answer:
She can make :
5 3/5 pies
Algebraic equation =
1 1/4 p = (9 - 2)
Step-by-step explanation:
Clara has 9 pounds of apples. If she saves 2 pounds for applesauce, how many pies, p, can she make?
Total number of pounds of apples = 9 pounds
She saves 2 pounds for apple sauce
The number of pounds of apples left =
9 pounds - 2 pounds
= 7 pounds
She needs 1 1/4 pounds to make one apple pie.
Therefore
1 1/4 pounds = 1 apple pie
7 pounds = p
Cross Multiply
1 1/4 × p = 7 × 1
p = 7 ÷ 1 1/4
p = 7 ÷ 5/4
p = 7 × 4/5
p = 28/5
p = 5 3/5 pies
An Algebraic equation for this situation is:
1 1/4 p = (9 - 2)
Where p = Number of pies
Find each of the following angles and arcs formed in circle R. (PLEASE HELP!! WILL MARK BRAINLIEST!)
Answer:
m<RTV = 90°
m<TRU = 129°
m<TVU = 51°
m<TSU = 64.5°
mST = 101°
mSTU = 230°
Step-by-step explanation:
i just did it:)
The measure of each angles are; m<RTV = 90°, m<TRU = 129°, m<TVU = 51°, m<TSU = 64.5°, mST = 101° and mSTU = 230°.
What is a circle?A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.
Since Angle RTV is formed by the segments RT - that is the radius of the circle, and TV, which is tangent to the circle at point T. The radius always forms a right angle with the tangent lines.
Hence, the measure of angle RTV is; 90°.
The measure of a central angle and the measure of the intercepted arc would be equal. Hence, the measure of angle TRU is 129°.
Since RTVU is a quadrilateral. We know that 3 of the interior angles' measures are 90°, 90°, and 129°. The measures of the interior angles of any quadrilateral add up to 360°, the measure of angle TVU is 51°.
Thus the measure of angle TSU is 64.5°.
Also the sum of all consecutive arcs in a circle is 360°,
We know that mTU = 129° and mUS = 130° then the measure of arc ST is 101°.

Answer:
A) 3/56 + 27/56 = 30/56 ÷ 2/2 = 15/28
Step-by-step explanation:
So, there's 3/56 cities that have a lake and 27/56 cities that have a river.
Since the question is asking how much have a lake or river, we add them up.
3/56 + 27/56 = 30/56
(Divide by 2 since that's the common factor)
30/56 ÷ 2/2 = 15/28

find 0. round to the nearest degree. 15 4
Answer:
68.2
Step-by-step explanation:
You can use a^2+b^2=c^2 to find the length of the missing side, where c^2 is the hypotenuse (side 14).
5^2+x^2=14^2
25+x^2=196
x^2=196-25=171
x=13.0 (rounded)
Next, use one of sin or tan to find the missing angle.
Sin0=opposite/hypotenuse
Sin0=13/14
0=sin^-1(13/14)
0=68.213 (rounded)
The value of the angle asked is 69°.
Given is a right triangle, with base = 5 units and the hypotenuse is 14 units,
We need to find the angle θ which is between the base and the hypotenuse,
To find the angle θ between the base and the hypotenuse of a right triangle, we can use the trigonometric function cosine (cos).
The cosine of an angle is defined as the ratio of the length of the adjacent side to the length of the hypotenuse.
In this case, the base of the triangle is the adjacent side, and the hypotenuse is given as 14 units.
Therefore, we can use the following formula:
cos(θ) = adjacent/hypotenuse
Plugging in the values we know:
cos(θ) = 5/14
To find the angle θ, we need to take the inverse cosine (arccos) of both sides:
θ = arccos(5/14)
θ = 69°
Hence the value of the angle asked is 69°.

A
Line r intersects line p.
B Line ris parallel to line 2.
CLine ris 10 units above line p.
D
Line ris 10 units below line p.
Answer:
A. Line r intersects line p
Step-by-step explanation:
to find the second graph multiply the slope of line p by -10
slope is 1/5 or 0.2

The Sea Dragon, a pendulum ride at an amusement park, moves from its central position at rest according to the trigonometric function P(t)=−10sin(pi/3t), where t represents time, in seconds. How many seconds does it take the pendulum to complete one full cycle?
A= 3
B= 5
C= 6
D= 10
Answer:T = 2*Pi / (Pi / 3) = 6 seconds
Step-by-step explanation:
The time (in seconds) that it take the pendulum to complete one full cycle is given by: Option C: 6 (seconds)
What is the period of sine function?Trigonometric functions are periodic. They repeat their values after some specific constant input interval (constant depends on the trigonometric function chosen).
For sine function, its period is 2π
Thus, we get:
[tex]y = \sin(x) = \sin(x+2\pi) = \sin(x + 2\pi n) ; n \in \mathbb Z[/tex] integer, and y is some constant at some constant value of x)
For this case, the pendulum's motion is modeled by:
[tex]P(t) = -10\sin\left(\dfrac{\pi}{3} t\right)[/tex]
Let it takes 'd' seconds to do one full cycle, then we get:
[tex]P(t) = P(t+d) = P(t+2d) = P(t + nd); n \in \mathbb Z - \mathbb Z^{-}[/tex] (n is non-negative integer).
Using the formula, we get:
[tex]-10\sin\left(\dfrac{\pi}{3} t\right) = -10\sin\left(\dfrac{\pi}{3} (t + nd)\right)\\\sin\left(\dfrac{\pi}{3} t\right) =\sin\left(\dfrac{\pi}{3}t + \dfrac{\pi}{3}nd\right)[/tex]
But we know that:
[tex]\sin\left(\dfrac{\pi}{3} t\right) =\sin\left(\dfrac{\pi}{3}t +2\pi n\right)[/tex]
Thus, we get:
[tex]2\pi n = \dfrac{\pi}{3}nd\\[/tex] (compared for non-negative values of n)
This gives:
[tex]d = \dfrac{2\pi n \times 3}{\pi n} = 6[/tex] (in seconds)
Thus, the time (in seconds) that it take the pendulum to complete one full cycle is given by: Option C: 6 (seconds)

Hi there!
Your job, at least on this triangle, is pretty simple. This is a 45-45-90 triangle.
Because this is a 45-45-90 triangle, both legs are 5. That leaves us to find the hypotenuse, x.
And a 45-45-90 triangle's hypotenuse is easy. You just take the measure of one of the legs, or 5 in this case, and stick a [tex]\sqrt{2\\}[/tex] right next to it. So your answer will be:
[tex]5\sqrt{2}[/tex]
