76 baseballs and 24 bats were ordered.
Explanation:Let's assume that 'x' represents the number of baseballs ordered and 'y' represents the number of bats ordered.
We can set up two equations to solve for 'x' and 'y':
x + y = 100 (since the total number of items ordered is 100)4.50x + 20y = 822 (since the total cost of the purchase is $822)We can solve the system of equations using the substitution or elimination method. Let's use the elimination method by multiplying the first equation by 4.50:
4.50x + 4.50y = 4504.50x + 20y = 822Subtracting the first equation from the second equation eliminates 'x' and we can solve for 'y':
15.50y = 372
y = 24
Substituting the value of 'y' back into the first equation, we can solve for 'x':
x + 24 = 100
x = 100 - 24
x = 76
Therefore, 76 baseballs and 24 bats were ordered.
76 baseballs and 24 bats were ordered for the summer camp, costing $822 in total.
Let's denote the number of baseballs as [tex]\( B \)[/tex] and the number of bats as [tex]\( T \)[/tex].
We're given two pieces of information:
1. The total number of items ordered is 100, so [tex]\( B + T = 100 \)[/tex].
2. The total cost of the items is $822, so [tex]\( 4.50B + 20T = 822 \)[/tex].
We can solve this system of equations by substitution or elimination. Let's use the elimination method.
1. Multiply the first equation by 20 to match the coefficient of [tex]\( T \)[/tex] in the second equation:
[tex]\[ 20(B + T) = 20(100) \][/tex]
[tex]\[ 20B + 20T = 2000 \][/tex]
2. Subtract this modified first equation from the second equation:
[tex]\[ (4.50B + 20T) - (20B + 20T) = 822 - 2000 \][/tex]
[tex]\[ 4.50B + 20T - 20B - 20T = -1178 \][/tex]
[tex]\[ -15.50B = -1178 \][/tex]
3. Divide both sides by -15.50 to solve for [tex]\( B \)[/tex]:
[tex]\[ B = \frac{-1178}{-15.50} \][/tex]
[tex]\[ B \approx 76 \][/tex]
4. Now, substitute the value of [tex]\( B \)[/tex] back into the first equation to find [tex]\( T \)[/tex]:
[tex]\[ 76 + T = 100 \][/tex]
[tex]\[ T = 100 - 76 \][/tex]
[tex]\[ T = 24 \][/tex]
So, there were 76 baseballs and 24 bats ordered.

What is the equation of the line described below written in slope-intercept form? the line passing through point (0, 0) and parallel to the line whose equation is 3x + 2y - 6 = 0
Answer:
The slope intercept form of the required line is [tex]y=\frac{-3}{2}x[/tex].
Step-by-step explanation:
If a line is defined as
[tex]Ax+By+C=0[/tex] ... (1)
Then the slope of the line is
[tex]m=\frac{-A}{B}[/tex]
The given equation is
[tex]3x+2y-6=0[/tex] .... (2)
From (1) and (2), we get
[tex]A=3, B=2, C=-6[/tex]
The slope of the line is
[tex]m=\frac{-3}{2}[/tex]
The slope of parallel line is same. So, the slope of required line is -3/2.
The slope intercept form of a line is
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
The slope of required line is -3/2 and y-intercept is at (0,0).
[tex]y=\frac{-3}{2}x+0[/tex]
[tex]y=\frac{-3}{2}x[/tex]
Therefore the slope intercept form of the required line is [tex]y=\frac{-3}{2}x[/tex].

On Monday Mrs. Wise bought 3 lbs of apples at $4 per lb. On Tuesday, apples were on sale for 20% off so she bought another 5 lbs. What was the price of apples on Tuesday? NEED ANSWER ASAP!
It is given that on Tuesday, apples were on sale for 20% off. Now, we know that on Monday Mrs. Wise bought 3 lbs of apples at $4 per lb. This means that if we have a 20% off on Tuesday then this must be with respect to the price on Monday which is $4. Thus the price of Tuesday can be calculated as:
[tex] 4-\frac{20}{100}\times 4=4-0.8=3.2 [/tex]
Thus, the per pound price of apples on Tuesday was $3.2

What is the value of this expression when z = 36?

-26
The provided expression with 'z = 36' is incomplete and lacks an operation or additional numbers, making it impossible to calculate its value. The student is advised to provide the full expression for proper assistance.
Explanation:The student asked: What is the value of this expression when z = 36?
Unfortunately, there is a typographical error in the expression provided. It seems to be missing an operation or additional numbers. Given the format '/z', it seems like it should have been a mathematical operation involving the variable 'z'. However, without an operator such as '+' (plus), '-' (minus), '*' (multiply), or '/' (divide), we cannot determine what the expression is supposed to be or calculate its value given z = 36.
If this is an expression from a specific textbook or sheet, I recommend double-checking the source material for the correct expression. If it's a part of a larger problem or context, please provide the full details so that an accurate computation can be made.
Cassandra lives in Oklahoma and makes $60,000 a year. If the median annual income in Oklahoma is $64,105 and the median annual income in the United States as a whole is $50,233, is Cassandra likely to qualify for Chapter 7 bankruptcy?
Answer:
Cassandra is likely to qualify for Chapter 7 bankruptcy.
Step-by-step explanation:
Given scenario is : Cassandra lives in Oklahoma and makes $60,000 a year. The median annual income in Oklahoma is $64,105.
A person qualifies for chapter 7 bankruptcy, if his annual median income is below the median income of his state. So, here the annual median income of Cassandra is below the median income of her state, Oklahoma.
So, she will qualify for chapter 7 bankruptcy.

Step-by-step explanation:
how do you solve "z+ma=ba" solve for a
Final answer:
To solve the equation for a, subtract z from both sides, factor out a, and then divide by (m - b), resulting in a = -z / (m - b), assuming m and b are not equal.
Explanation:
To solve the equation z + ma = ba for a, we need to isolate a on one side of the equation. We can rewrite the equation, moving all terms involving a to one side and all other terms to the opposite side. This process is called collecting like terms.
Here are the steps to isolate a:
Subtract z from both sides of the equation to get ma = ba - z.
Since both terms on the right hand side involve a, factor a out: a ( m - b ) = -z.
Finally, divide both sides of the equation by (m - b) to solve for a: a = -z / (m - b), assuming that m ≠ b.
This algebraic manipulation gives us the value of a in terms of z, m, and b.

We will find the slope of each line.
Formula:
[tex]\text{Slope, m}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\text{Slope of AB, m}_1=\dfrac{3-3}{9+2}=0[/tex]
[tex]\text{Slope of BC, m}_2=\dfrac{6-3}{5-9}=-\dfrac{3}{4}[/tex]
[tex]\text{Slope of CD, m}_3=\dfrac{6-6}{2-5}=0[/tex]
[tex]\text{Slope of AD, m}_4=\dfrac{6-3}{2+2}=\dfrac{3}{4}[/tex]
Slope of AB = Slope of CD = 0
[tex]m_1=m_3=0[/tex]
Thus, AB is parallel to CD
Slope of BC ≠ Slope of AD
[tex]m_2\neq m_4[/tex]
Thus, BC is not parallel to AD
The quadrilateral ABCD has two sides are parallel and two are not parallel.

Factor completely. a2+3a−28 Enter your answer in the box.
Solution :
To factor completely
[tex] a^{2} + 3a-28 [/tex]
To factor it completely , first take the product of first and third term, and then break the second term in two parts in such a way that its sum equals the second term and the product equals the product of first and third term.
Product of first and third term is [tex] (a^{2})(-28) = -28 a^{2} [/tex]
Second term is 3a, Re-write 3a as sum of 7a and -4a.
Lets check it Product of 7a and -4a is [tex] -28 a^{2} [/tex] wich is eaqual to product of first and third term and sum of 7a and -4a is 3a which is the second term.
Now factorise, we get
[tex] a^{2}+3a-28\\\\ = a^{2} +7a-4a-28\\\\=a(a+7)-4(a+7)\\\\=(a+7)(a-4) [/tex]
Hence, [tex] (a+7)(a-4) [/tex] is the factor of [tex] a^{2}+3a-28 [/tex].

1.One of the lamp posts at a bank has a motion detector on it, and the equation (x+15)2+(y−12)2=25 describes the boundary within which motion can be sensed.
What is the greatest distance, in feet, a person could be from the lamp and be detected?
5 ft
10 ft
50 ft
125 ft
Answer:
5ft
Step-by-step explanation:
The required greatest distance, in feet, a person could be from the lamp and be detected is 5 ft. Option A is correct.
The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the center of the circle on the coordinate plane and r is the radius of the circle.
Here,
Given equation
(x+15)²+(y−12)²=25
The above equation is the equation of the circle, so the longest distance that person could be from the lamp and be detected is the radius of the circle,
Which is given as,
r² = 25
r = √25
r = 5
Thus, the required greatest distance, in feet, a person could be from the lamp and be detected is 5 ft. Option A is correct.
