1a) 4:2 = 2
4.98 x 2 = $9.96
1b) 3:2 = 1 1/2
4.98 x 3/2 = $7.47
2a) 9:3 = 3
4.80 x 3 = $14.40
2b) 12:3 = 4
4.80 x 4 = $19.20
3a) 6:2 = 3
15.00 x 3 = $45.00
3b) 5:2 = 2 1/2
15.00 x 5/2 = $37.50
Answer:
Step-by-step explanation:
Given

Required
Find x
From the attachment, we have:
Because both triangles are similar, we use the following equivalent ratios:
Substitute values for each parameter
Convert to fractions
Simplify the right-hand side
Cross Multiply

Solve for x
Answer:
69
Step-by-step explanation:
If she is averaging 65% of the worth of lectures.
the lectures she had was supposedly rated out of 60. Therefore, the 65% will be 65% of 60(total grade)
0.65 * 60 = 39
On the second part, if we apply the same method, we have
0.75 * 40 = 30
All we have to do on add both together
39 + 30 = 69.
therefore, get total grade in the course is 69
If you simply want to multiply the answers given to you I would say answer c. 6lbs peanuts, 3 pound almonds and 2lb raisins. If you multiply 6*1.50 you get 9, you multiply 3*3.00 would also equal 9, and 2*1.50 is 3. 9+9+3=21
Answers: x = 4 and y = 3
============================================================
Explanation:
Triangle UBD is congruent to triangle RAN
Note the order of the lettering as it's important.
BD and AN are the last two letters of UBD and RAN in that order. Therefore, these sides correspond and BD = AN. From that, we know,
BD = AN
2y+5 = 3y+2
5-2 = 3y-2y
3 = 1y
y = 3
-----------
Using similar logic, UD and RN are the first and last letters of UBD and RAN respectively. So,
UD = RN
15 = 2x+7
2x+7 = 15
2x = 15-7
2x = 8
x = 8/2
x = 4
