Answer:
option A
a = 8.65 m/s²
Step-by-step explanation:
Given that,
force applied on a cart (forward direction) = 19N
frictional force experience by cart (backward direction) = 1.7N
mass of the cart = 2 kg
Frictional force always opposes applied force, so the Resultant force on the cart would have to be 19N - 1.7N.
Formula to use
Resultant force = ma
plug values in the formula
19 - 1.7 = 2(a)
17.3 = 2(a)
a = 8.65 m/s²
so the acceleration of the cart is 8.65m/s²
12/-30=8x
cross multiply
12x=-240
x=-20
Answer:
£2720
Step-by-step explanation:
106%=2883.20
100%=x
106x=288320
divide both by 106 it gives 2720
Answer:
m∠1 = 70
Step-by-step explanation:
A line is 180 degrees
The angles of a triangle total to 180 degrees
180 - 101 = 79
79 + 31 = 110
180 - 110 = 70
Answer:
A. 1:8
Step-by-step explanation:
We have been given that several students were asked to name the kinds of animals they saw in the past week at the park.
Dogs: 8
Cat: 2
Fish: 4
Lizard: 2
We are asked to find the ratio that compares the number of cats seen to the total number of animals seen.
Let us find total number of animal by adding each type of animals as:


We can see that the students saw 2 cats, so ratio of cats to total animals would be
.
Dividing 2 and 16 by 2, we will get:

Therefore, the ratio 1:8 compares the number of cats seen to the total number of animals seen and option A is the correct choice.
