What is R,S,W? I really need help!
Answers
Answer:
R- 73°
S- 73°
W- 138°
Step-by-step explanation:
Every triangle is 180°.
So 65+42=107
180-107=73
So that's the triangle to the right.
Now the other one is identical.
So we know the line w is on is 180°
On the corner w is on it took up 42°
So 180-42= 138° (which is 'w')

What is the answer for number 11
Answers
Answer: C
Step-by-step explanation: First you have to do y-y÷x-x. So first you do 2-3 which gives you -1. Then you do 6-4 which gives you 2. Then you divide -1÷2 which gives you -0.5x. Now you know it's either C or D because it's negative. For the y-intercept, you have to plug in one of the ordered pairs to y and x using the slope-intercept form.
Which of the following equations is equivalent to 2(a + 6) – 3(a – 5) = 18?
A: 5a + 27 = 18
B: 5a - 3 = 18
C: -a + 27 = 18
D: -a + - 3 = 18
Answers
use distributive property:
2(a+6)-3(a-5)+15=18
2a+12-3a+15=18
combine like terms:
2a+12-3a+15=18
-a+27=18

Answers
Answer:156
Step-by-step explanation: 26÷1/6 =26×6 =156
The intensity level is moderate
In one second Corey's heart will beat 3 times.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Corey's heart beats 26 times in 1/6 minutes.
Assume that her heart beats [x] times in 1 second. Then -
1/6 of minute = 1/6 x 60 = 10 seconds
In 10 seconds, her heart beats 26 times
So, in one second, her heart will beat (26/10) = 2.6 times = 3 times (approx.).
Therefore, in one second Corey's heart will beat 3 times.

An AP is given by k,2k/3,k/3,0 .....Find the sixth term. find the nth term. If the 20th term is equal to 15, find k
Answers
9514 1404 393
Answer:
6th term: 8k/3n-th term: an = k + (k/3)(n -1)k = 45/22 for 20th term = 15Step-by-step explanation:
You know the general term of an AP is ...
an = a1 +d(n-1)
Here, a1 = k. The common difference is ...
2k/3 -k = -k/3
So, the general term is ...
an = k +(k/3)(n -1) . . . . the general term
__
The 6th term is then ...
a6 = k + (k/3)(6 -1) = (3k +5k)/3 = 8k/3 . . . . 6th term
__
The 20th term is ...
a20 = k + (k/3)(20 -1) = 22k/3
If this is 15, then the value of k is ...
22k/3 = 15
22k = 45
k = 45/22 . . . . value of k for a20 = 15

What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given table is as follows:-

Here the x-values represent the depth, in meters. The y-values represent the pressure in atmospheres (atm).
The ratio between the values x and y is 15:3 or 30:6 or 5 :1. From the given options the additional set of values that could be included in the table having the same ratio of 5:1 is ( 10, 2 ).
Therefore, the additional set of values that could be included in the table will be (10, 2). the correct option is A.

A box of Shredded Wheat weighs 0.35 kg and a box of Weetabix weighs 9/25 kg?
Which box is heavier?
Show your work
PLEASE HELP DUE TONIGHT THANK YOU SO MUCH
Answers
Answer: The box of Weetabix is heavier by 0.01 kg
Step-by-step explanation:
Divide 9/25 to get the decimal equivalent
9÷25 =0.36
Compare Shredded Wheat at 0.35 kg to Weetabix at 0.36 kg
Weight of the box of Shredded Wheat is [tex]0.35[/tex] kg and weight of the box of Weetabix is [tex]0.45[/tex] kg.
So, the box of Weetabix is heavier.
Weight of the box of Shredded Wheat [tex]= 0.35[/tex] kg.
Weight of the box of Weetabix [tex]= \frac{9}{25}[/tex] kg.
Here to compare the two weights, first make both of them similar.
Either make both of them decimals or both of them fraction.
Here, we will make both the weights decimals.
[tex]\frac{9}{20} = 0.45[/tex]
Now, [tex]0.45>0.35[/tex]
So, the box of Weetabix is heavier.

The ellipse is centered at the origin, its major axis is horizontal, with length 8; the length of its minor axis is 4;
Answers
Consider we need to find the equation of ellipse.
Given:
Ellipse is centered at the origin.
Major axis is horizontal, with length 8.
The length of its minor axis is 4.
To find:
The equation of ellipse.
Solution:
Major axis is horizontal, so standard form of ellipse is
[tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1[/tex] ...(i)
where, (h,k) is center of the ellipse and length of major axis is 2a and length of minor axis is 2b.
Ellipse is centered at the origin. So, h=0 and k=0.
Major axis is horizontal, with length 8.
[tex]2a=8[/tex]
[tex]a=4[/tex]
The length of its minor axis is 4.
[tex]2b=4[/tex]
[tex]b=2[/tex]
Substitute h=0, k=0, a=4 and b=2 in equation (i).
[tex]\dfrac{(x-0)^2}{4^2}+\dfrac{(y-0)^2}{2^2}=1[/tex]
[tex]\dfrac{x^2}{16}+\dfrac{y^2}{4}=1[/tex]
Therefore, the required equation of ellipse is [tex]\dfrac{x^2}{16}+\dfrac{y^2}{4}=1[/tex].
