Answer:
Yes she will reach her goal
Step-by-step explanation:
The total miles to be skated by Maribel on monday is 1 1/2 miles.
On Monday morning she skates 9/10miles
If on Monday afternoon she skates 8/9 of that distance on Monday, then she must have skate (8/9 of 9/10) miles in the afternoon which is equivalent to 4/5miles.
Total miles she skated will be 9/10+4/5 = 9+8/10
= 17/10
= 1 7/10 miles
This means that she will reach her goal and even pass the initial total miles she wanted to skate which is 1 1/2miles
I think it is b .because negative numbers are less than anything
Answer:
One length = 10
Two length = 20
One width = 2
Two width = 4
Step-by-step explanation:
The perimeter is 24
A rectangle has 4 sides
2 are length
other 2 is width
First, the length is 8 inches longer
there are 2 length so 8 + 8 = 16
That leave 8 inches left
divide 8 by 4 = 2
Add one length together
8 + 2 = 10
2 is the width
How to check you answer:
10 + 10 + 2 + 2 =24
The value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We know that:
P + Q are complementary, which means that
P+Q = 90°
Then R is a right angle, i.e. it measures 90°.
sin(90-x) = cos (x)
cos(90-x) = sin (x)
Then sinQ = 4/5
cos(90-Q) = cosP = 4/5
Now sin²(P) + cos²(P) = 1
sin²(P) = 1 - cos²(P)
sin²(P) = 1 -[4/5]² =9/25
sin(P) = 3/5
cos(Q) = sin(P) = 3/5
cos(P) + cos(Q) = 4/5 + 3/5 = 7/5
Thus, the value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.
