Answer:
The plastic model is 50 meters tall
Step-by-step explanation:
Here, we want to know how tall is the plastic model
In the plastic model 10 m represents 65 meters
then x meters plastic = 325 m real
10 * 325 = 65 * x
3250 = 65x
x = 3250/65
x = 50 meters
Answer:
a15 = 35
Step-by-step explanation:
Given:
a3 = 11
a6 = 17
Find:
a15 = ?
Computation:
a3 = 11 ⇒ a+ 2d = 11..........Eq1
a6 = 17 ⇒ a + 5d = 17...............Eq2
From Eq2 - Eq1
⇒ 3d = 6
⇒ d = 2
And a = 7
So,
⇒ a15 = a + 14d
⇒ a15 = 7 + 14 (2)
⇒ a15 = 7 + 28
⇒ a15 = 35
Let the number of islands visited be x and that peninsulas be y
thus,
x+y=19
⇒y=19-x.........i
if he skydives twice in islands and thrice in peninsulas, then the total number of skydives will be:
2x+3y=45.....ii
substituting i in ii we get:
2x+3(19-x)=45
2x+57-3x=45
putting like terms together we get:
2x-3x=45-57
-x=-12
therefore
x=12
and
y=19-x=19-12=7
hence the number of islands visited was 12 and that of peninsulas was 7
Answer:
b
Step-by-step explanation:
<ABC refers just to angle B. Angle B is on the opposite side of 98 therefore we would have to divide it by two. 98 divided by 2 is 49
