The area of the parallelogram is 45 square miles. Find its base and height
Final answer:
The student's question involves finding the base and height of a parallelogram given its area. Without additional information, there are infinite base-height combinations possible. The formula used is base multiplied by height equals the area of the parallelogram.
Explanation:
The student is asking about the relationship between the base, the height, and the area of a parallelogram. To find the base and height from the area, the formula for the area of a parallelogram is used, which is base x height = area. With an area of 45 square miles, if we have the measurement of either the base or the height, we can divide the area by that measurement to find the other dimension. However, with only the area given, the base and height can't be uniquely determined; there are infinitely many combinations of base and height that yield the same area. For instance, if the base is 9 miles, the height would be 5 miles, or if the base is 15 miles, the height would be 3 miles, and so on.

Answer:
10cm Base
Step-by-step explanation:
Actually the answer is 10 cm for the base.
First step is take 1600cm2 and divide it by 4 (or how many pendents you have) so it'll look like this
1600/4 =400cm2
Then you need to find the area of the Triangles.
Area of the Triangle=1/2xbase xheight
400=1/2xbx80
400=40xb
10=b
Answer: 10cm Base

The cost y (in dollars) to rent a camping tent is proportional to the number x of days that the tent is rented. It costs $56 to rent a tent for 7 days. Write an equation that represents the cost to rent a camping tent for x days.
Answer:
[tex]y=8x[/tex]
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]
In this problem the linear equation represent a proportional variation
Let
x------> the number of days
y-----> the cost to rent a camping tent
The linear equation is equal to
[tex]y=kx[/tex]
we know that
It costs [tex]\$56[/tex] to rent a tent for [tex]7[/tex] days
Find the value of k
[tex]56=7k\\ \\k=56/7\\ \\k=8\frac{\$}{day}[/tex]

Venetta buys 2 pounds of pistachios and 3 pounds of almonds. The pistachios cost $4 more per pound than the almonds. She pays a total of $48. Which of the following are true? Select all that apply.
A. One pound of pistachios plus 1 pound of almonds cost $20.
B. The pistachios cost twice as much per pound as the almonds.
C. Reducing the number of pounds of almonds by one results in a total cost of $40. D. The cost a, in dollars, of 1 pound of almonds is modeled by 2(a – 4) + 3a = 48. E. The cost p, in dollars, of 1 pound of pistachios is modeled by 2p + 3(p – 4) = 48.
We want to find a system of equations, and by solving that system we will be able to see which statements are true.
We will see that options A, C, and E are true.
We know that:
Venetta buys 2lb of pistachios
Venetta buys 3 lb of almonds.
Let's define the variables:
x = price per pound of pistachios
y = price per pound of almonds.
Now we also know that:
"The pistachios cost $4 more per pound than the almonds."
This can be written as:
[tex]x = y + \$4[/tex]
"She pays a total of $48"
This can be written as:
[tex]2*x + 3*y = \$48.[/tex]
So a system of equations:
[tex]x = y + \$4[/tex]
[tex]2*x + 3*y = \$48.[/tex]
To solve this system, the first thing we need to do is isolate one of the variables in one of the equations, particularly we can see that x is already isolated in the first equation, so we can skip that step.
Now we can replace the isolated variable in the other equation to get:
[tex]2*(y + \$4) + 3*y = \$48[/tex]
now we can solve this for y:
[tex]2*y + \$8 + 3*y = \$48[/tex]
[tex]5*y + \$8 = \$48[/tex]
[tex]5*y = \$48 - \$8 = \$40[/tex]
[tex]y = \$40/5 = \$8[/tex]
now that we know this, we can use:
[tex]x = y + \$4 = \$8 + \$4 = \$12[/tex]
now that we know:
y = $8
x = $12
Let's see which statements are true:
A) One pound of pistachios plus 1 pound of almonds cost $20.
True, $8 + $12 = $20.
B) The pistachios cost twice as much per pound as the almonds.
False, $12 is not the double of $8.
C) Reducing the number of pounds of almonds by one results in a total cost of $40.
True, one pound less of almonds means $8 less in the price.
D) The cost a, in dollars, of 1 pound of almonds is modeled by 2(a – 4) + 3a = 48
Simplifying the expression we get:
2*(a - 4) + 3a = -8 + a = 48
a = 48 + 8 = 52
This clearly does not model the price of one pound of almonds, this statement is false.
E) The cost p, in dollars, of 1 pound of pistachios is modeled by 2p + 3(p – 4) = 48.
Solving the equation we get:
2*p + 3*p - 12 = 48
5*p = 48 + 12 = 60
p = 60/5 = 12
This is true.

A football team receives the ball on their own ten yard line. They make a gain of fifteen yards in the first play. What yard line is the ball on? What represents zero in this situation? Explain
The summation of 10 yds and fifteen yds is 25 yds thus the ball is the on 25 yd line and the zero represents the ball is in the net and goals.
What is summation?The summation is to add or subtract any two or more terms by doing that operation we will get a new result which could be big or small depending upon the number.
There could be only two terms, but there could be one hundred, a thousand, or a million.
As per the given question,
The initial position of the ball = 10 yd line
The team gained 15 yds in the first play.
Therefore, New position of the ball = 10 yds + 15yds = 25 yds

if an obtuse angle is split in half, how can the two new angles be classified? give an example.
Splitting an obtuse angle in half will either result in two acute angles or right angles, depending on the original angle's measure.
When an obtuse angle is split in half, each of the two new angles will be either acute or right angles, depending on the measure of the original obtuse angle. An obtuse angle is one that is greater than 90 degrees but less than 180 degrees.
By splitting an obtuse angle exactly in half, both resulting angles will have a measure less than 90 degrees, making them acute, unless the original angle was exactly 180 degrees, in which case the split would result in two angles of 90 degrees each, making them right angles.
Consider the obtuse angle, ABC, which measures 120 degrees. When we bisect angle ABC to create two new angles, namely ABD and DBC, each of these angles will measure 60 degrees, classifying them as acute angles.

The diameter of the new cell, which is exactly half the diameter of the original cell (4.32 x 10^-4 millimeters), is 2.16 x 10^-4 millimeters.
Explanation:The lab technician is dividing a cell with an original diameter of 4.32 x 10^-4 millimeters. The new cells' diameter is stated to be exactly one half of the original diameter. Therefore, to find the diameter of the new cell, simply take half of the original cell's diameter. This can be accomplished by dividing the numerical value of the diameter by 2, which would be 4.32/2 = 2.16. The exponent remains the same because the size (magnitude) of cell diameter is only halved, not the order magnitude. So the diameter of the new cell is 2.16 x 10^-4 millimeters.

0.64 divided by 4 in standard algorithm
Answer:
Quotient = 0.16, Remainder = 0
Step-by-step explanation:
Standard algorithm of division is a step by step procedure to perform division.
In this question we have to divide 0.64 by 4, therefore, 0.64 is the dividend and 4 is the divisor.
Steps:
Zero times four is 0. Then we put decimal point in our quotient.
Continuing one times 4 is 4. We subtract 4 from 6 to have remaining value of 2. Then, we copy down 4. Thus, the remaining value now is 24.
Six times four is 24. Thus, the remaining value is zero.
Hence, we get the remainder of zero and quotient 0.16.
When 0.64 is divided by 4 using standard algorithm, we get 0.16.
What is Division?
Division in maths is the process of breaking a number up into equal parts, and finding out how many equal parts can be made.
