First simplify the fractions: 1 1/2 + 3/10 Then add the fractions together: 0.8 Then you have 1.8.
Hey, Aneseyia313! 5/10+3/10 No adding the denominators(bottom number), you only add the numerators(top number). 5+3=8 8/10 1+0=1 1 8/10 8/10=4/5 1 4/5 I hope this helps;)
The time in seconds between seeing lightning and hearing thunder is about five times the storm's distance in miles. Write a function to represent the storm's distance f(s) given the time s. How far away is a storm if this time is 15 seconds?
Answers
f(s)=5s f(s)=5(15) f(s)=75 At 15 seconds, the storm would be approximately 75 miles away.
A quadrilateral has angles that measure 87°, 69°, and 104°. What is the measure of the fourth angle?
Answers
The answer should be ................... 100
Sum of angles of quadrilateral = 360
87 + 69+ 104 + x = 360
156 + 104 +x = 360
260 + x = 360
thus, x = 100
Thus, the measure of the fourth angle is 100 degrees
write 5.6% as a decimal
Answers
0.056 That should be right
.56 is ur answer.......
A regular octagon has sides measuring about 4cm. If the octagon is divided into 8 congruent triangles, each has a height of 5 cm. What is the area of the octagon?
Answers
Base of each triangle = about 4 cm Height of each triangle = 5 cm
Area of each triangle = (1/2) (base) (height) and there are 8 of them.
Total area = (8) x (1/2) x (base) x (height) =
(4) x (about 4 cm) x (5 cm) = about 80 cm² .
The area of a triangle is 1/2*base*height
So, do that for one of the triangles, since they're all the same 1/2*4*5=10cm squared
Multiply by 8 to find the total
10*8=80
80 cm squared.
