Answer:
Angles 2 and 3 are supplementary to each other
Step-by-step explanation:
A supplementary angle is 2 angles that when you add the sum is 180.
So, first what we should do is divide 2,046 by 62 to find the width of Lucas's banner.
2,046 / 62 = 33 The width of Lucas's banner is 33 cm.
Which means if the width of Emily's banner is 3x that:
3 x 33 = 99 Emily's banner is 99 cm in width.
So, your 2 answers are: 99 cm, division and multiplication. ;)
Answer:
Index of refraction of transparent is 1.48
Step-by-step explanation:
Snell's law states that;
n1(sinθ1) = n2(sinθ2)
Where;
n1 and n2 represent the indices of refraction for the two media, and θ1 and θ2 are the angles of incidence and refraction that the ray R makes with the normal.
In this question;
n1 = 1;
θ1 = 43.8°
θ2 = 19.3°
n2 is unknown.
Thus using Snell's law, we have;
1 x sin 43.8 = n2 x sin 19.3
n2 = (sin 43.8)/sin 19.3
n2 = 1.48
You need to add and multiply because there a keyword name many so it add and multiply so 1 .2+8=answer and of you get the answer multiplayer it by 1.2 bpth
The number of brownies Mariel brought home is 8
<u>Explanation:</u>
Given:
Total number of brownies, n = 48
Class ate = 
= 40
Mariel brought rest of the brownies home.
So, the number of brownies Mariel brought home = 48 - 40
= 8
