Answer:
38.60mm
Step-by-step explanation:
Step one:
Given data
We are given that the dimension of the triangles are length 23 mm and 31 mm
Let us assume that the triangle is a right angle triangle
Step two:
Applying the Pythagoras theorem we can find the third as
square both sides
z= √ 1490
z= 38.60mm
Hence a possible dimension of the third side is 38.60mm
Answer:
(a) and (b) are true
Step-by-step explanation:
a) is true.
b) is true. Replacing x with 8 in the equation y=1/4x-5 results in 2-5, or -3.
c) is false. See (a), above.
d) is false. Replacing x in the equation by 12 results in y = (1/4)(12) - 5, or -2.
Answer:
10
Step-by-step explanation:
When u cross multiply
= 3x=30(5*6)
= x=30/3
=x=10
Answer:
B: 60
Step-by-step explanation:
f(x)= 5x+10, if x=10
f(10)=5(10)+10
5(10)+10=60
f(10)=60
<h3>
Answer: 10/9 hours</h3>
Work Shown:
3/20 of a yard = 1/6 of an hour
(20/3)*(3/20 of a yard) = (20/3)*(1/6 of an hour)
1 yard = 20/18 of an hour
1 yard = 10/9 of an hour
In the second step, I multiplied both sides by 20/3 to have that initial "3/20 yard" turn into "1 yard".
The improper fraction 10/9 is equivalent to the mixed number 1 & 1/9. Both are roughly equivalent to the decimal value of 1.11; so it takes roughly 1.11 hours for Jerry to mow the full lawn.
