Answer:
The numbers or measurements being compared are called the terms of the ratio. A rate is a special ratio in which the two terms are in different units. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.
Step-by-step explanation:
Answer: the amount of dimes is $1.15 this is also equivalent to 11 dimes and an extra nickel.
Explanation:
80 nickels =$4.00
$5.15-$4.00= $1.15
11 dimes= $1.10
1 nickel= $0.05
$1.10+$0.05= $1.15
hope this helps! :)
Answer:
Step-by-step explanation:
The given box in both questions are cuboid.
Question 3:
Volume of cuboid = length * width * height
= 3 * 3 * 5 = <u>45 units.</u>
Question 4:
Volume of cuboid = length * width * height
= 4 * 2 * 6 = <u>48 units</u>
C=2pi(r)
Pi=3.14
r=5.5
So C=2(3.14)(5.5)=34.56
So the circumference is 34.56 mi
And the area is A=pi(r)²
So you have
A=3.14(5.5)²
So A=95.03 mi²
So the area is 95.03 mi² and the circumference is 34.56 mi
Hope this helps!

Equation Given :
-------------------------------------------------------
16x² = 121
-------------------------------------------------------
Take away 121 from both sides:
-------------------------------------------------------
16x² - 121 = 0
-------------------------------------------------------
Make each term a perfect square
--------------------------------------------------------
(4x)² - (11)² = 0
--------------------------------------------------------
Apply algebraic rule : a² - b² = (a + b)(a - b)
--------------------------------------------------------
(4x + 11) (4x - 11) = 0
-------------------------------------------------------
Apply zero product property :
-------------------------------------------------------
4x + 11 = 0 or 4x - 11 = 0
--------------------------------------------------------
Solve for x :
--------------------------------------------------------
4x = - 11 or 4x = 11
x = -11/4 or x =11/4
--------------------------------------------------------------------------
Answer: x = -11/4 or x = 11/4
--------------------------------------------------------------------------
