Hello from MrBillDoesMath!
Answer:
This is the second choice from the top ( - 5.81)
Discussion:
The five terms are:
-3 - 3/2 - 3/4 -3/8 - 3/16 =
-3 ( 1 + 1/2 + 1/4 + 1/8 + 1/16) =
-3 (31/16) =
-93/16 =
-5 13/16 =
- 5.8125 ( approximately)
This is the second choice from the top
Thank you,

Answer:
Round 4264 to the nearest hundred so the answer is 4300.
So the equation for this would be y= 90x where y would be the distance in feet covered in x seconds and x would be seconds. So to find out the distance covered in 25 seconds you would plug in 25 for x.
y= 90(25)
y= 2250
So to answer the question you would say that the cheetah would cover 2,250 feet in 25 seconds.
Answer:
h=6 feet
Step-by-step explanation:
Given: 1. The base of a rectangle is three feet longer than its height.
2.Are of the rectangle=54 square meters
Let us say the rectangle has height h and base(breadth) b.
Since, the base of the rectangle is three feet longer than the height, we have b=h+3.
Also, Area of the Rectangle= hb
therefore, 54=h(h+3)
54= h2+ 3h
h2+3h-54=0 (Subtract 54 from both the sides)
To find the value of h we have to solve the quadratic equation.
[We have the equation in the form ax2+bx+c=0, to factorise the equation-
Step1. Find two numbers such that their multiplication is equal to ac and their addition is equal to b.
Step2. Replace b with these numbers.
Step3. Simplify the equation]
So, h2+3h-54=0
h2+9h-6h-54=0
h(h+9)-6(h+9)=0
(h+9)(h-6)=0
Which gives-
h= -9 or h= 6
As h is the height of the rectangle, h can not be -9.
so h=6 feet
and b=h+3=9 feet
So the dimensions of the rectangle are 6 feet for the height and 9 feet for the base.
Answer: each cupcake was 6.75
Step-by-step explanation: 12.00 + 3.50 =15.50 29.00- 15.50 is 13.50 divide by 2 boom 6.75 is each cupcake
