Priya is mixing drops of food coloring to create purple frosting for a cake she uses 24 drops of red dye and 16 drops of blue dye find the ratio of drops of red dye to total drops of dye
Answer:
24:40
Step-by-step explanation:
To find the radio for red dye to total drops of dye, just add the red and blue dye.
The ratio of drops of red dye to total drops of dye is 3:2.
What is Ratio?When a number is divisible by another number, then it can be written in the form of a:b, this is called Ratio.
Priya is making frosting.
The number of drops of blue dye is 16.
The number of drops of red dye is 24.
Ratio ( Red dye : Blue dye) = 24 : 16
Ratio ( Red dye : Blue dye) = 3:2

What is the image point of (1,-2)(1,−2) after a translation right 4 units and down 4 units?
Answer:
(-3, 2)
Step-by-step explanation:
If we are dealing with vertical movement up/down, we manipulate the x-axis.
If we are dealing with horizontal movement left/right, we manipulate the y-axis.
We are trying to move the point right 4 units (horizontal movement) and down 4 units (vertical movement).

Please help asap! I will gave brainlest!
Step-by-step explanation:
I know that
[tex] \cot {}^{2} (x) + 1 = \csc {}^{2} (x) [/tex]
So These the steps I need to do:
First Apply Reciprocal Identies to find Cot x.
[tex] \frac{1}{ \tan(x) } = \cot(x) [/tex]
So cot x is
[tex] \frac{24}{7} [/tex]
Now, I can squared that result and add 1 to get csc^2(x).
[tex] \frac{576}{49} + 1 = \frac{576}{49} + \frac{49}{49} = \frac{625}{49} [/tex]
Now, I take the principal square root since csc is positve when theta is in the 1st quadrant.
[tex] \frac{ \sqrt{625} }{ \sqrt{49} } = \frac{25}{7} [/tex]
So
[tex] \csc(x) = \frac{25}{7} [/tex]
[tex]cosec{\theta=\frac{25}{7}is\ the\ answer.}[/tex]
Step-by-step explanation:[tex]If\ tan\ \theta=\frac{7}{24},0\ degrees < \theta < 90\ degrees[/tex]
[tex]sec\ \theta=\sqrt{1+\tan^2\theta}=\sqrt{1+\frac{49}{576}}=\sqrt{\frac{625}{576}}=\frac{25}{24}[/tex]
[tex]cos\ \theta=\frac{1}{sec\ \theta}=\frac{24}{25}[/tex]
[tex]sin\ \theta=\sqrt{1-\cos^2\theta}=\sqrt{1-(\frac{24}{25})^2}=\sqrt{\frac{49}{625}}=\frac{7}{25}[/tex]
[tex]cosec\ \theta=\frac{1}{sin\ \theta}=\frac{25}{7}[/tex]
[tex]Hence,\ cosec\ \theta=\frac{25}{7}is\ the\ answer.[/tex]

8.A golfer swings a club about a pivot point. If the head of the club travels a distance of 26 feet and rotates through an angle of 5 radians, which of the following gives the distance the club head is from the pivot point?
The distance the club head is from the pivot point is about 5.2 feet.
What is a circle?A circle is the locus of a point such that its distance from a fixed point known as the center is always constant.
Let r represent the radius of the circle, that is the distance the club head is from the pivot point. Hence:
Length of arc = angle in radians * radius
26 = 5r
r = 5.2 feet
The distance the club head is from the pivot point is about 5.2 feet.

x-4(3-2x) = 3(3x+4)
Find X
Answer:
all x are the solution
Step-by-step explanation:
x - 4×3 - 4×(-2x) = 3×3x + 3×4
x - 12 + 8x = 9x +12
9x + 12 = 9x + 12
9x = 9x
(0 = 0)
no matter which number we take for x the equation will always be correct
ex. x = 3 : left : 9×3 = 27
right : 9×3 = 27

Find f(-2)
f(-2) =

Answer: 10
Step-by-step explanation:
Since -2 is in between -5 and 0, we will use the part of the function that says f(x)=x^2 + 3x.

In the year 2000, the height of an apple tree was
150 centimeters. In the year 2020, the same tree has
grown to 270 centimeters. What was the average rate
of change in the height of the tree from 2000 to 2020?
In other words: On average, how fast was the tree
growing? Include units.
Answer:
(270+150)/(2020-2000)= 21 - average rate of change in the height per year
Answer:
I think to get the average rate you subtract 150 from 270 centimetres you'll get 120 centimetres then subtract 2000 from 2020 to get 20 now to get the rate divide 120cm by 20 and you will get six so the rate is 6 cm per year

For what values of a are the following expressions true?
1. |a-5|=5-a
2.|a|=-a
Answer:
1. a = 0 and 5
2. no solutions
Step-by-step explanation:
For absolute value, it's the distance from that number on the number line to 0, so it has to be positive. We define absolute value as when |a| = b, a = b and a = -b.
1. |a - 5| = 5 - a
a - 5 = 5 - a
2a = 10
a = 5
AND
a - 5 = -(5 - a)
a - 5 = -5 + a
-5 = -5
a = 0 (a could work as 0 in this scenario)
Thus our solutions are a = 0 and 5.
2. |a| = -1
Now we have to catch ourselves here. Since absolute value is always positive, nothing works. There is no negative distance to 0 (at least in real numbers). Hence, we can say that there are no solutions.

Add two smaller shapes' area together
Find the area of this circle.
A= ?
5 in
Hint: First, plug in the value
of the radius into the
formula for r.
If radius, r = 5in., then we can compute that the area of the circle = 78.55in² or approximately 79in².
Using the formula, Area of Circle = πr²
It is given in the question, r = 5in and as we know that the value of π = 3.142
Now, putting the values from above in the formula of area of circle, we will get:
A = π × 5² = 3.142 × 25 = 78.55
= 79in² (to the nearest whole number).
The space a circle takes up in a two-dimensional plane is known as its area. Alternately, the area of a circle is the area contained within the circumference or boundary of the circle. The sum of the square units inside that circle is another name for it.
