Answer:
$2600 I believe
Step-by-step explanation:
Since he puts $75 in his account every week and he save his money for 24 weeks, 75 times 24= 1800 and he already had $800 in his account, so 1800+ 800= 2600

Andre builds a form for a new cement step in the shape of a rectangular prism. The form he builds is 40 and 1/2 inches long, 10 inches deep, and 8 inches high. How much cement is needed to fill the form?
Answer:
3240 in^3
Step-by-step explanation:
Step one:
given data
The dimension of the form
Length 40 and 1/2 inches long,
Depth 10 inches deep,
The width and 8 inches high
Step two:
The amount of cement is equivalent to the volume of the form
[tex]V=L*W*H\\\\V=40.5*10*8\\\\V=3240 in^3[/tex]
Hence the volume of cement is 3240 in^3
The set of ordered pairs below represents a function.
{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}
Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.
Select all ordered pairs that could be used to show that this claim is incorrect.
(–9, –6)
(1, 12)
(–10, –10)
(4, 7)
(–5, 1)
Given:
The set of ordered pairs below represents a function.
{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}
Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.
To find:
All the ordered pairs that could be used to show that this claim is incorrect.
Solution:
We need to find the ordered pairs that can be replaced with (6,-10) and for which the set is not a function.
A relation is called function if there exist a unique output for each input.
If (-9,-6) is replaces with (6,-10), then the set has two outputs y=1 and y=-6 for x=-9. So, the claim is incorrect.
If (1,12) is replaces with (6,-10), then the set has two outputs y=12 and y=3 for x=1. So, the claim is incorrect.
If (-10,-10) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.
If (4,7) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.
If (-5,1) is replaces with (6,-10), then the set has two outputs y=1 and y=2 for x=-5. So, the claim is incorrect.
Therefore, the correct options are (a), (b) and (e).

The expressions that are equivalent to [tex]3\frac{1}{4} -(-\frac{5}{8} )[/tex] are
[tex]3\frac{1}{4} +(\frac{5}{8} ) \\\\3\frac{1}{4} +(+\frac{5}{8} )[/tex]
for understanding check the calcualtions here
Calculationan expression is the combination of numbers and operators like +, - * or /
If we have any equal sign then it is an equation .
Given expression is :
[tex]3\frac{1}{4} -(-\frac{5}{8} )[/tex]
to find out equivalent expression we remove the parentheisis by multiplying negative inside the parenthesis
Negative times negative becomes positive
first fraction is positive . So it remains the same
Multiply negative inside the parenthesis . Negative times negative is positive
so, the equivalent expressions are
[tex]3\frac{1}{4} +(\frac{5}{8} ) \\\\3\frac{1}{4} +(+\frac{5}{8} )[/tex]

John bought 12 items from the concession stand. He bought cokes and nachos for his friends. Cokes cost $2.50 each and Nachos cost $3.50 each. He spent a total of $37. How many Nachos did he buy?
Answer: He bought 7 nachos.
Step-by-step explanation:
Let x= Number of cokes
y = Number of nachos
As per given , we have
x+y=12 (i)
2.50x+3.50y=37 (ii)
Multiply 2.5 on both sides of (i), we get
2.5x+2.5y= 30 (iii)
Subtract (iii) from (ii), we get
y=7 (iv)
Put value of y from (iv) in (i), we get
x+7=12
⇒ x= 12-7
⇒ x=5
Hence, he bought 5 cokes and 7 nachos.

____________________________________________________________
It takes Buddy 94 years to be 100 so you would add 94 to both boys ages!
6+94=100 years old!
3+94= 97 years old!
Answer:
He is going to be 50 years old
Step-by-step explanation:
if he was 3 when his brother was 6 then it would mean that when his brother is 100 he should be 50 because that would be half. You can divide it if you want some extra proof :)

The points (-4, 3) and (4, r) lie on a line with slope 1/2
Find the missing coordinate r.
Answer:
7
Step-by-step explanation:
8 units separate -4 and 4
8 divided by 2 (which is the x of slope) is four
Four times 1 (which is y of slope) equals four
3+4 equals seven

determine the domain of the following graph
Answer: [tex]-2 \leq x \leq 9[/tex]
Step-by-step explanation:
The domain is the set of x-values for which the relation is defined.
The domain of the graph will be -2 ≤ x ≤ 9 which is shown in the given figure.
What are the domain and range of the function?The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.
The domain of a graph is the set of all possible input values (also called the independent variable) that can be plotted on the graph. In other words, it is the range of values that the horizontal axis (also called the x-axis) of the graph covers.
To determine the domain of a given graph, you will need to look at the labels and scale of the x-axis.
The domain of a graph is the set of all possible input values in intervals as -2 ≤ x ≤ 9 that can be plotted on the graph.
Thus, the domain of the graph will be -2 ≤ x ≤ 9, as indicated in the illustration.
