A certain orange colour requires mixing 5 parts of red paint with 7 parts of yellow paint.Roderick mixed 15 parts of red paint with 21 parts of yellow paint. Did he create the correct orange colour?

Answers

Answer 1

Answer:

Roderick has created the correct orange color.

Explanation:

The orange color required mixing 5 parts of red paint with 7 parts of yellow paint. The ratio is given below:

[tex]\operatorname{Re}d\colon\text{Yellow}=5\colon7[/tex]

Roderick mixed 15 parts of red paint with 21 parts of yellow paint. This is expressed in ratio as:

[tex]\begin{gathered} \operatorname{Re}d\colon\text{Yellow}=15\colon21 \\ \text{Divide both sides by 3} \\ \frac{15}{3}\colon\frac{21}{3}=5\colon7 \end{gathered}[/tex]

Since the two ratios reduces to the same value, they are equivalent, thus Roderick has created the correct orange color.

There are given that the graph of the triangle.

Now,

According to the properties,

If the point (x, y) or (-x, y) rotated about the origin by the angle of 360 degrees.

That means,

There is no difference between rotating 360 degrees clockwise or anti-clockwise around the origin.

Then,

From the vertices of the triangle ABC is:

[tex]\text{A is (-6, 3), B is (-5, 7) and C is (-4, 3).}[/tex]

Since the triangle map onto itself

[tex]\begin{gathered} A=A^{\prime} \\ B=B^{\prime} \\ C=C^{\prime} \end{gathered}[/tex]

So, the triangle is rotated 360 degrees about the origin

Hence, the correct option is D.

P(X = x) 0.2, 0.2, 0.2, 0.2, 0.2. Find the value of P(X<3).

Answers

The value of the probability P(x < 3) is 0.8

How to determine the probability value?

From the question, the table of values is given as

x = -1,0,1,2,3.

P(X = x) 0.2, 0.2, 0.2, 0.2, 0.2

To calculate the probability P(x < 3). we make use of the probability values where x is less than 3

This means that

P(x < 3) = P(-1) + P(0) + P(1) + P(2)

Substitute the known values in the above equation

So, we have

P(x < 3) = 0.2 + 0.2 + 0.2 + 0.2

Evaluate the sum

P(x < 3) = 0.8

Hence, the probability value is 0.8

How do you convert 313313 yards to inches? Use the drop-down menus to explain your answer.Since there are inches in 11 yard, 313313 by .So, 313313 yards = inches.

Answers

Given:

[tex]3\frac{1}{3}\text{yards}[/tex]

We need to convert yards into inches.

Explanation:

[tex]3\frac{1}{3}\text{yards}=\frac{3\times3+1}{3}\text{ yards}[/tex]

[tex]3\frac{1}{3}\text{yards}=\frac{10}{3}\text{ yards}[/tex]

to determine if the sequence is arthimetic or a geometric progression, we check if a common difference or common ratio exists between the two sequence

the sequence is 36, 30, 24, 18,......

from careful observation, this is an arthimetic progression because a common difference exists between them

Write the equation for the trigonometric graph.y= 8cos(pi/40x)y= –8sin(pi/40x)y= –8cos(pi/40x)y= 8sin(pi/40x)

Answers

Solution

For this case we can verify the answer using the point x= 0 if we replace we got:

y=8 cos (pi/40* 0) = 8 cos (0) = 8

y= -8 sin (pi/40 *0)= -8 sin(0) = 0

y= -8cos(pi/40*0)= -8 cos (0)= -8

y= 8 sin (pi/40 *0)= 8 sin(0) = 0

Then the correct option would be:

y= -8cos(pi/40*0)

The point (7,6) is not on the circle

STEP-BY-STEP EXPLANATION:

(a)

The equation of the circle is given as follows:

[tex]\begin{gathered} (x-h)^2+(y-k)^2=r^2 \\ \text{ where (h,k) is the center and r is the radius } \end{gathered}[/tex]

We replace to calculate the radius of the circle, like this:

[tex]\begin{gathered} \mleft(-4-3\mright)^2+\mleft(1-\mleft(-7\mright)\mright)^2=r^2 \\ (-7)^2+(8)^2=r^2 \\ r^2=113 \end{gathered}[/tex]

Therefore, the equation would be:

[tex](x-3)^2+(y+7)^2=113[/tex]

(b)

We replace the point, and if the value is greater than the radius, it means that this point is not on the circle:

[tex]\begin{gathered} (x-3)^2+(y+7)^2\le113 \\ \text{ replacing:} \\ \mleft(7-3\mright)^2+\mleft(6+7\mright)^2\le113 \\ 4^2+13^2\le113 \\ 16+169\le113 \\ 185\le113 \end{gathered}[/tex]
