Answer:
42 min
Step-by-step explanation:
Joanna takes 2 mins to send a text.
2 mins = 2 x 60 sec = 120 sec
Anna takes 40 seconds to send a text
120 ÷ 40 = 3
Anna can text 3 messages in 120 sec
Together, in 120 sec ,
both of them can send out 1 + 3 = 4 texts
Number of 120 seconds needed to send 84 texts
= 84 ÷ 4
= 21
Number of seconds needed
= 21 x 120
= 2520
25020 sec = 2620 ÷ 60 min = 42 min
Answer:
5.50 + 1.50x = 19
x = 9
Ava can ride <u>9</u> rides.
Step-by-step explanation:
5.50 + 1.50x = 19
-5.50 -5.50
1.50x = 13.50 (divide both sides by 1.50)
x = 9
Answer:
2587mm^3 approx!
Step-by-step explanation:
first you divide the nut into 6 part(in triangle now, by joining centre to each edge)
let's take one part of the triangular shape then area of that part can be found by using 1/2×base×height
i.e, 1/2×13×15=97.5(mm^2)
now when we consider depth of that traingular part,we will get volume of that part as area×depth
i.e, 97.5×6=585(mm^3)
now volume of all the 6 triangular part is 585×6=3510(in mm^3)
now take circular cavity in consideration, it's volume will be π(7^2)6=923(mm^3) approximately
now reqired volume will be volume of that hexagonal part minus that of circular cavity
=3510-923
=2587mm^3
