Marvin used a customary unit of measure to estimate the weight of a watermelon he grew in his backyard what could the estimated weight be
Answer:
Usually pounds (lb) .About an an average of 20 to 25 pounds (lbs)
Step-by-step explanation:
Since Marvin uses Customary units, and considering the Watermelon.
Pounds, He could estimate based on average of 20 to 25 pounds.
He could choose another customary units, but it wouldn't be practical and unusual to say a watermelon of 160 quarters, also it would leave all the listeners without parameters.
So, definitely pounds.
steve has a photo and a rectangular piece of card. the photo is 16cm by 10cm. the card is 30cm by 15cm. steve cuts along the dotted line shown in the diagram below teve throws away the piece of card that is 15 cm by x cm. The piece of card he has left is mathematically similar to the photo. Work out the value of x.
Answer:
24cm
Step-by-step explanation:
The photo stays the same, the card changes. They must be proportional to each other.
15 by x cm means the 30 is going to be shortened, since it is being cut.
16 / 10 = 1.6
1.6 x 30 = 24
or
[tex]\frac{16}{10} = \frac{x}{15} \\\\Divide\\\\\frac{16}{10} *\frac{15}{x} = \frac{240}{10x} = 24[/tex]

The base of a solid oblique pyramid is an equilateral triangle with a base edge length of 18 inches. A solid oblique pyramid has an equilateral triangle base with an edge length of 18 inches. What is the height of the triangular base of the pyramid? 9 √ 2 in. 9 √ 3 in. 18 √ 2 in. 18 √ 3 in.
Answer:
b.[tex]9\sqrt{3}in[/tex]
Step-by-step explanation:
We are given that
Length of equilateral triangle=a=18 in
Base of oblique pyramid is an equilateral triangle.
We have to find the height of the triangular base of the pyramid
Height of the triangular base of the pyramid,h=[tex]acos\theta[/tex]
We know that each angle of equilateral triangle =60 degree
[tex]\theta=\frac{60}{2}=30^{\circ}[/tex]
Substitute the values
Height of triangular base of the pyramid,h=[tex]18cos30=18\times \frac{\sqrt 3}{2}[/tex]in
Using the value of
[tex]cos30^{\circ}=\frac{\sqrt 3}{2}[/tex]
Height of triangular base of the pyramid,h=[tex]9\sqrt{3}in[/tex]

PQ⊥PS , m∠QPR=7x−9, m∠RPS=4x+22
Find : m∠QPR
Given:
It is given that,
PQ ⊥ PS and
∠QPR = 7x-9
∠RPS = 4x+22
To find the value of ∠QPR.
Formula
As per the given problem PR lies between PQ and PS,
So,
∠QPR+∠RPS = 90°
Now,
Putting the values of ∠RPS and ∠QPR we get,
[tex]7x-9+4x+22 = 90[/tex]
or, [tex]11x = 90-22+9[/tex]
or, [tex]11x = 77[/tex]
or, [tex]x = \frac{77}{11}[/tex]
or, [tex]x = 7[/tex]
Substituting the value of [tex]x = 7[/tex] in ∠QPR we get,
∠QPR = [tex]7(7)-9[/tex]
or, ∠QPR = [tex]40^\circ[/tex]
Hence,
The value of ∠QPR is 40°.

Divide the sum of 3/4 and −4/7 by their difference
Answer:
5/37.
Step-by-step explanation:
Sum:
3/4 + -4/7
= 21/28 - 16/28
= 5/28
Difference:
3/4 - (-4/7)
= 3/4 + 4/7
= 21/28 + 16/28
= 37/28.
Dividing:
5/28 / 37/28
= 5/28 * 28/37
= 5/37.

One zip Weighs as much as three zaps two zaps weight as much as five zowies three zowies weigh as much as two swooshes if one weighs sixty pounds how much does a zip weigh
Answer:1 zip weighs 30 lb
Step-by-step explanation:
3 zowies = 12 lb. so, 1 zowie = 4 lb.
2 zap = 20 lb. so, 1 zap = 10 lb.
1 zip = 30 lb.
One zip weighs 360 pounds.
1. One zip weighs as much as three zaps.
2. Two zaps weigh as much as five zowies.
3. Three zowies weigh as much as two swooshes.
4. One swoosh weighs 60 pounds.
We need to find the weight of one zip.
Step 1: Find the weight of one swoosh.
Since one swoosh weighs 60 pounds, we have:
1 swoosh = 60 pounds
Step 2: Find the weight of three zowies.
Since three zowies weigh as much as two swooshes, and one swoosh weighs 60 pounds, we have:
3 zowies = 2 swooshes = 2 * 60 = 120 pounds
Step 3: Find the weight of two zaps.
Since two zaps weigh as much as five zowies, and three zowies weigh 120 pounds, we have:
2 zaps = 5 zowies = 120 pounds
Step 4: Find the weight of one zip.
Since one zip weighs as much as three zaps, and two zaps weigh 120 pounds, we have:
1 zip = 3 zaps = 3 * 120 = 360 pounds
The height of a cylinder is twice the radius of its base. A cylinder has a height of 2 x and a radius of x. What expression represents the volume of the cylinder, in cubic units? 4πx2 2πx3 πx2 + 2x 2 + πx3
Step-by-step explanation:
The height of a cylinder is twice the radius of its base.
Let the height of the cylinder = 2x
Let the radius of the cylinder = x
By formula, volume of the cylinder = π[tex]r^{2}[/tex] h
here r = x, h = 2x
substituting the values in the equation, we get
volume of the cylinder = π[tex]r^{2}[/tex] h = π [tex]x^{2}[/tex] (2x)
volume of the cylinder = 2π[tex]x^{3}[/tex]
The expression that represents the volume of the cylinder is 2x³π.
What is the volume of the cylinder?A cylinder is a three-dimensional object that is made up of a two circles that are attached to a rectangle.
Volume of a cylinder = πr²h

Which relation describes a function?
{(0,0), (0, 2), (2.0), (2, 2)}
{(-2, -3), (-3, -2), (2,3), (3, 2)}
{(2,-1), (2, 1), (3,-1), (3, 1)}
{(2, 2), (2, 3), (3, 2), (3, 3)}
Answer:
{(-2, -3), (-3, -2), (2,3), (3, 2)}
Step-by-step explanation:
A function is a set of ordered pairs in which no two pairs have the same first number.
In other words, an x cannot be paired with two y's.
A function takes an x and pairs it with one and only one y.
{(0,0), (0, 2), (2.0), (2, 2)} is not a function because it pairs 0 with both 0 and 2.
{(2,-1), (2, 1), (3,-1), (3, 1)} is not a function because it pairs 2 with both -1 and 1.
{(2, 2), (2, 3), (3, 2), (3, 3)} is not a function because it pairs 2 with both 2 and 3.

Fraction 2/3 has greatest value among the fractions 1/3, 2/3, and 2/9.
Greatest fraction to be determine among the fractions 1/3, 2/3, and 2/9.
What is the fraction?
Fraction is defined as the number of composition constitute the Whole.
Here,
1/3 = 0.33, 2/3 = 0.66 and 2/9 = 0.22.
2/3>1/3>2/9
Thus, fraction 2/3 has greatest value among the fractions 1/3, 2/3, and 2/9.
In circle P diameter QS measures 30 cm.

a. 7.2 cm
b. 25.8 cm
c. 94.2 cm
d. 14.4 cm
PLEASE HURRY!! I HAVE LIMITED TIME!! :)
Given:
The diameter of the circle P is 30 cm.
The radius of the circle P is 15 cm.
The measure of ∠RPS is 125°
We need to determine the arc length of QR.
Measure of ∠QPR:
The angles QPR and RPS are linear pairs.
Thus, we have;
[tex]\angle QPR + \angle RPS=180^{\circ}[/tex]
Substituting the values, we have;
[tex]\angle QPR + 125^{\circ}=180^{\circ}[/tex]
[tex]\angle QPR =55^{\circ}[/tex]
Thus, the measure of ∠QPR is 55°
Arc length of QR:
The arc length of QR can be determined using the formula,
[tex]Arc \ length =(\frac{\theta}{360})2 \pi r[/tex]
Substituting [tex]\theta=55[/tex] and r =15, we get;
[tex]Arc \ length =(\frac{55}{360})2 (3.14)(15)[/tex]
[tex]Arc\ length = \frac{5181}{360}[/tex]
[tex]Arc \ length =14.4 \ cm[/tex]
Thus, the arc length of QR is 14.4 cm.
Hence, Option d is the correct answer.

Answer: "distance from zero on a number line"
Explanation: Absolute value means "distance from zero" on a number line.
Since distance can either be 0 or positive,
absolute value is either 0 or positive.
Absolute value is represented with vertical bars on either side of the number.
An example is shown below, we have the absolute value of -5.
The absolute value of a number is just
the positive version of that number.
So the positive version of -5 is 5.

Okay, we are going to solve this backwards!
First, we need to know that the formula for circumference is
c = π × d
d = diameter
π = 3.14
They told us what the circumference is, so let's plug it in
75 = (3.14) × (d)
let's solve for d
[tex]\frac{75}{3.14} = d[/tex]
d = 23.88 inches
We must remeber that the radius is HALF of the diameter, so let's divide the diameter by 2
[tex]\frac{23.88}{2} = 11.94[/tex]
Now, let's round to the nearest whole inch like they suggested
11.94 ≈ 12
The answer is 12 inches!
Jaxson and his children went into a movie theater and he bought $42.50 worth of drinks and candies. Each drink costs $6 and each candy costs $3.25. He bought a total of 8 drinks and candies altogether. Write a system of equations that could be used to determine the number of drinks and the number of candies that Jaxson bought. Define the variables that you use to write the system.
Answer:
6d+3.25c=42.50
d+c=8
Step-by-step explanation:
let's say d is for drinks and c is for candy.
each drink is $6
each candy is $3.25
the porblem told us our total $42.50
so if we mulitpy the cost of each drink and candy together
6d+3.25c=42.50
and
Since he bought a total of 8 drinks and candies, we know that d+c=8
Answer:
Let d = the number of drinks
Let c = the number of candies
6d+3.25c=42.50
d+c=8
