Manuel bought 9 pounds of apples.
He has eaten 3
4 of a pound so far and has
$15 worth of apples left. Write and solve an
equation to find the cost of the apples per
pound to the nearest dollar. How much did
the apples cost per pound?
Answers
Answer:
1) Since Manuel bought 9 pounds and ate 3/4 of 1 pound, he has 8.25 pounds left (9 - 0.75 = 8.25)
2) Let's call "x" the cost of 1 pound of apples
3) (8.25)*(x) = $15
4) x = $1.81818 rounded to the nearest dollar is $2 / pound

Create an equation that models the total number of calories Jonathan consumes,y,based on number of biscuits he eats,x,and the 6 packages of pemmican
Answers
An equation that models the considered calorie consumption by Jonathan is y = mx + 6k, where m is the number of calorie per buiscuit, and k is the number of calorie per package of pemmican.
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
We're specified that:
x = number of buiscuits Jonathan eastsy = number of calories Jonathan consumes6 = number of packages of pemmican that jonathan consumes.Let we take:
m = number of calories per buiscuit that Jonathan eats.
Then, for x buiscuits, it would be [tex]m \times x[/tex] calories, or in short [tex]mx[/tex] calories.
Let k = number of calories per package of pemmican, then:
for 6 packages of pemmican, it would be [tex]6 \times k[/tex] calories, or in short [tex]6k[/tex] calories.
Thus, total calories Jonathan consumes = y = calories from x buiscuits + calories from 6 packages of pemmican.
or, we get:
[tex]y = mx + 6k[/tex]
Thus, an equation that models the considered calorie consumption by Jonathan is y = mx + 6k, where m is the number of calorie per buiscuit, and k is the number of calorie per package of pemmican.

g(x) = 4x² will be the equation of the parabola.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
Given, two parabolas f(x) and g(x),
From the general equation of the parabola,
y = a(x – h)² + k or x = a(y – k)² +h.
Here (h, k) denotes the vertex.
As we can see in our case, the vertex is (0, 0)
Thus, the equation of the parabola will be
y = ax²
Since the given parabola passes through the point (1, 4)
Substitute the values,
4 = a(1)²
a = 4
therefore, the equation of the parabola g(x) will be,
g(x) = 4x²

Is 0.3 the multiplicative inverse of 3 1/3? Why or why not?
Chapter : Rational Numbers
Answers
Answer:
3 1/3 = 10/3
0.3 = 3/10
a * 1/a =1
then 1/a is multiplicative inverse of a
0.3* 3 1/3 = 3/10 * 10/3 =1
0.3 is multiplicative inverse of 3 1/3
Step-by-step explanation:
Answer:
3 1/3 = 10/3
10.3 = 0.3 = 3 1/3
x * 1/x = 1
∴ yes, the multiplicative reverse of 3 1/3 is 0.3

First you put the entries in ascending order, because that's how the line plot needs to be ordered.
1/4, 3/8, 1/2, 3/4, 7/8, 1, 1 1/4
So right there, you can rule out A.
You can rule out C because 1/4 does not occur 5 times in the data set.
B is incorrect because 3/8 isn't on the line plot at all.

Victor sold cupcakes and cookies yesterday. Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the
day, Victor had sold $95.25 worth of cookies and cupcakes. If he sold 68 cupcakes and cookies combined, how many
cupcakes were sold and how many cookies were sold?
Answers
answer:number of cupcakes sold is 13 Number of cookies sold is 27
Step-by-step explanation:
Let x represent the number of cupcakes that Victor sold. Let y represent the number of cookies that Jane sold. Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the day, This mean Victor had 2.25x 0.5y = 42.75 - - - - - - - - - -1she sold 40 cupcakes and cookies combined, it means thatx y = 40Substituting x = 40 - y into equation 1, it becomes2.25(40 - y) 0.5y = 42.7590 - 2.25y 0.5y = 42.75- 2.25y 0.5y = 42.75 - 90- 1.75y = - 47.25y = - 47.35/-1.75y = 27x = 40 - yx = 40-27 = 13
An equation is formed when two equal expressions. The number of cupcakes that Victor sold is 35, while the number of cookies that Victor sold is 33.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of cupcakes sold be represented by x, while the number of cookies sold is represented by y.
Now, the total number of cupcakes and cookies sold combined is equal to 68. Therefore, the equation can be written as
x + y = 68
x = 68 - y
Also, Each cupcake sold for $2.25 and each cookie sold for $0.50. And the total sale that Victor made is of $95.25. Therefore, the equation can be written as,
2.25x + 0.50y = 95.25
2.25(68 - y) + 0.5y = 95.25
153 - 2.25y + 0.5y = 95.25
-2.25y + 0.5y = 95.25 - 153
1.75y = 57.75
y = 33
Now, substitute the value of x in the first equation.
x + y = 68
x + 33 = 68
x = 35
Hence, the number of cupcakes that Victor sold is 35, while the number of cookies that Victor sold is 33.

Find the diagram attached.
Note that in a cyclic quadrilateral, the sum of the opposite side of the quadrilateral is 180degrres.
According to the diagram shown:
<D+<I = 180
<D+45 = 180
Subtract 45 from both sides
<D+45-45 = 180-45
<D = 180-45
<D= 135°

The problem is that you cannot be sure that either triangle (it actually requires both of them) contain a right angle
What you have so far is SSA which is not one of the fundamental congruency triangles. In order to be certain of congruency the angle must be made up of the 2 given sides. You are certain that SAS will produce congruency. You are not so sure of r SSA. There are proofs of this on the internet. I urge you to look into it. Though not long, following it step by step takes a lot of patience. A cup of strong coffee is a good idea.
