Answer:
34 mph Is correct answer
Step-by-step explanation:
Average speed = total distance / total time
Total distance = ( 40 × 2 + 30 × 3 )
= 170 miles
Total time = 5 h
So, avg speed = 170/5 = 34 mph

In the school store, pencils cost 15 cents each and erasers cost 10 cents each. There is no tax. Gabby wants to spend exactly $2.00 on pencils and erasers.
How many of each can she buy? Provide detail explanation of your solution process and all possible strategies.
she bought 10 pencils and 5 erasers
Let x represent the number of pencils and y represent the number of erasers.
Gabby wants to spend exactly $2.00 on pencils and erasers, hence:
0.15x - 0.1y = 2 (1)
Therefore x = 10 and y = 5
Therefore she bought 10 pencils and 5 erasers.

Answer:
1,304,0006Step-by-step explanation:
You may recall that when you learned multiplication of decimals, there were two facts involved:
the total number of decimal digits when two decimal numbers are multiplied is the sum of the numbers of decimal digits in each onemultiplying by 10 adds a zero on the right. (Multiplying by 10^n adds n zeros on the right.)__
Here, we combine these facts.
Multiplying the decimal number 1.304 by 1000000 will add 6 zeros to the right of 1304 to make it 1304000000. Placing the decimal point in this product so there are 3 decimal digits (as there are in 1.304) makes this number be ...
1,304,000.000 . . . . . . product of 1.304 and 1,000,000
You will notice the decimal point in 1.304 has effectively moved 6 places to the right.

What is the equation written in vertex form of a parabola with a vertex of (9, -1) that passes through (7. 7)?
O
A. y = 2(x - 992 - 1
B. y = 2(x + 1)2 - 9
O C. y = 2(x - 7)2 + 7
D. y = 7(x - 9)2 - 1
Answer:
[tex]y = 2\, (x - 9)^{2} - 1[/tex].
Step-by-step explanation:
If the vertex of a parabola is [tex](h,\, k)[/tex], there would exist a constant [tex]a[/tex] ([tex]a \ne 0[/tex]) such that the following would be an equation for this parabola:
[tex]y = a\, (x - h)^{2} + k[/tex].
The equation above is in the vertex form.
In this question, the vertex of this parabola is [tex](9,\, -1)[/tex]. (Such that [tex]h = 9[/tex] and [tex]k = -1[/tex].) Therefore, the equation of this parabola in the vertex form would be:
[tex]\text{$y = a\, (x - 9)^{2} + (-1)$ for some $a \ne 0$}[/tex].
It was also given that the point [tex](7,\, 7)[/tex] is on the parabola. In other words, if [tex]x = 7[/tex] and [tex]y = 7[/tex], the equation of this parabola ([tex]\text{$y = a\, (x - 9)^{2} + (-1)$}[/tex]) should be satisfied. In other words:
[tex]7= a\, (7 - 9)^{2} + (-1)[/tex].
Solve this equation for [tex]a[/tex].
[tex]a = 2[/tex].
Therefore, the equation of this parabola in vertex form would be[tex]y = 2\, (x - 9) + (-1)[/tex], which is equivalently [tex]y = 2\, (x - 9)^{2} - 1[/tex].

Answer:
1 Answer: Since these two lines are the same line, they have infinite solutions Answer: So first thing you gotta do is multiply the first equation by 5. Your first equation will be. Since these two lines are the same line, they have infinite solutions.
Another Answer: You would have to multiply either equation in order to get one of the variables to cancel.
I would multiply the first equation by -5.
-5(3x + 6y = -2)
-15x -30y = 10
15x + 30y = -10
0 + 0 = 0
Since everything cancels and the equation is true, the solution is Infinitely many solutions, or all real numbers.

Step-by-step explanation:
take 2 1\4 divid by 2 = 1 1/4 cup
Answer:
1.5 cupsStep-by-step explanation:
Given
2 packages = 3 batches ⇒ 1 batch = 2/3 packages1 package = 2 1/4 cupsEach recipe is
2/3 packages = 2/3 * 2 1/4 = 2/3 * 9/4 = 3/2 cups = 1.5 cupsjacob said the product of 8/9 and 2 and 3/4 is 3 and 1/4. how can you tell that his answer is wrong?
Answer:
he is wrong becuase 89 times a number greater than 0 cannot result in a product greater than the number
Step-by-step explanation:
Based on real algebra properties, we know that the product of 8/9 and 2 and 3/4 is not 3 and 1/4.
How to infer the correctness of a product?The multiplication of two positive integers equals another positive integer. Each term of a multiplication can be rewritten as sums of multiples of 10, which can be simplified by algebra:
Given; Definition of multiplication
8/9 and 2 = 26/9
3/4
The product is;
26/9 x 3/4
= 13 x 1/6
= 13/6
Based on real algebra properties, we know that the product of 8/9 and 2 and 3/4 is not 3 and 1/4.
