The chapter 7 test will have 20-30 questions on it. Novanet!
Answer:
We can conclude that the chapter 7 test will also have 20-30 questions on it.
Step-by-step explanation:
All tests for the first six chapters of a textbook had 20–30 questions.
The chapter 7 test will be given tomorrow.
Hence, based on reasoning, we can say that the chapter 7 test can also have 20-30 questions in it.
The probability is also high as all the 6 previous tests had 20 to 30 questions. Hence, it is very likely that the 7th test will also have same number of questions.

steven spent $90on clothes.he bought a pair of jeans that cost $34 and spent the rest on t shirts that cost $8.
I'm not sure what the question is but if your trying to find out how many t-shirts he bought it would be 7.
Here's why...
90$-34$= 56
56/8= 7
He could buy 7 shirts with the left over money he had.
Hope this answered your question. :)
~Noodles~
Final answer:
Steven spent $90 in total, bought jeans for $34, and used the remaining $56 to buy T-shirts that cost $8 each, allowing him to purchase 7 T-shirts.
Explanation:
The student’s question is a simple mathematics word problem involving subtraction and division. Steven spent a total of $90 on clothes. After purchasing jeans for $34, he used the remainder of his money to buy T-shirts costing $8 each. To solve this, we first subtract the cost of the jeans from the total amount to find out how much money was left for T-shirts:
$90 (total amount) - $34 (cost of jeans) = $56
Next, we calculate the number of T-shirts Steven could buy with the remaining $56 by dividing this amount by the cost of one T-shirt:
$56 ÷ $8 (cost per T-shirt) = 7 T-shirts
Therefore, Steven was able to purchase 7 T-shirts with the rest of his money.

Step-by-step explanation:
a line contain the points (82,-96) and (87,-86) . what is the slope of the line in simplification form ?
y=2x−26 because the form for standard slope is: y=mx+b
you have to find the slope by doing y-y/x-x and then you plug the slope you get into m and then you pick a point; either (82,-96) or (87,-86) and you plug it in for the x and y in y=mx+b and you work out the equation from there.

Tickets to a concert cost $2 for children, $3 for teenagers and $5 for adults. When 570 people attended the concert, the total ticket receipts were $1950. Three-fourths as many teenagers as children attended. How many adults attended?
Answer: 220
Step-by-step explanation:
Children (x): $2
Teens (y): $3, [tex]\frac{3}{4}x[/tex]
Adults: (z): $5
Quantity: x + y + z = 570 ⇒ x + [tex]\frac{3}{4}x[/tex] + z = 570 ⇒ 1.75x + z = 570
Cost: 2x + 3y + 5z = 1950 ⇒ 2x + 3[tex](\frac{3}{4}x)[/tex] + 5z = 1950 ⇒ 2x + 2.25x + 5z = 1950 ⇒ 4.25x + 5z = 1950
Qty: 1.75x + z = 570 → 5(1.75x + z = 570) → 8.75x + 5z = 2850
Cost: 4.25x + 5z = 1950 → -1(4.25x + 5z = 1950 → -4.25x - 5z = -1950
4.50x = 900
x = 200
Teens (y): [tex]\frac{3}{4}x[/tex]
y = [tex]\frac{3}{4}(200)[/tex]
= [tex]\frac{600}{4}[/tex]
= 150
Quantity: x + y + z = 570
200 + 150 + z = 570
350 + z = 570
z = 220
Work out the probability it is a humbug.
Please help!!
The probability of an eclair is 1/15, which means for every 1 eclair there is a total of 15 sweets.
Since the table says there is 3 eclairs, there is 3 x 15 = 45 total sweets.
Now add the 3 different sweets together to equal 45:
3 + 2x+6 + x = 45
Combine like terms:
3x +9 = 45
Subtract 9 from each side:
3x = 36
Divide each side by 3:
X = 36 /3
x = 12
Now you have x, calculate the number of humbugs:
2x +6 = 2(12) +6 = 24 + 6 = 30 total humbugs.
The probability of picking one would be 30/45, which reduces to 2/3.

Juan is constructing a doghouse . He need four pieces of Ply wood that are 2 ft x 3 ft rectangles. He also needs two pieces of plywood that are 2 ft x 2 fr squares . How many square feet of plywood is he purchasing in all?
Final answer:
Juan will be purchasing 32 square feet of plywood in all for constructing the doghouse, calculated by summing the areas of four 2 ft x 3 ft rectangular pieces and two 2 ft x 2 ft square pieces.
Explanation:
Juan is constructing a doghouse and needs to calculate the total square footage of plywood required for both rectangular and square pieces. To determine this, we calculate the area of each piece of plywood and then sum them up. The area of a rectangle is given by multiplying its length by its width, and for a square, each side is of equal length, so we multiply the length of one side by itself to find the area.
The four rectangular pieces are 2 ft by 3 ft, so each one has an area of:
2 ft × 3 ft = 6 square feet
Since there are four such pieces, this amounts to:
4 pieces × 6 square feet per piece = 24 square feet
The two square pieces are 2 ft by 2 ft, so each one has an area of:
2 ft × 2 ft = 4 square feet
Thus, the total for the two square pieces is:
2 pieces × 4 square feet per piece = 8 square feet
Adding both totals together, Juan will be purchasing:
24 square feet + 8 square feet = 32 square feet of plywood in all.
Identify the range of the function.
The range of the function is -4 < x ≤ 4.
The range of a function is all of the values of y that the graph could contain. In this case, x varies between -4 and 4. We should have a < symbol at -4 because it doesn't include -4 due to the open circle. We should have a ≤ with 4 since it has a closed dot.
Two siblings Edwin and Rhea are both going skiing but choose different payment plans. Edwin's plan charges $45 for rentals and $5.25 per lift up the mountain. Rhea's plan was a bundle where her entire day cost $108. Set up an inequality that models the number of trips, n, up the mountain for which Edwin will pay more than Rhea. Solve the inequality. Also, what is the greatest amount of trips that Edwin can take up the mountain and still pay less than Rhea? Explain how you arrived at your answer.
The greatest amount of trips that Edwin can take up the mountain and still pay less than Rhea would be 63.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Two siblings Edwin and Rhea are both going skiing but choose different payment plans.
Edwin's plan charges $45 for rentals and $5.25 per lift up the mountain.
Rhea's plan was a bundle where her entire day cost $108.
An inequality that models the number of trips, n, up the mountain for which Edwin will pay more than Rhea.
45 + 5.25n > 108
Subtract 45 on both sides
-45 + 45 + 5.25n > 108 -45
5.25n > 63
Divide both sides by 5.25
n > 12
Also,
5.25 x 12
= 63
The greatest amount of trips that Edwin can take up the mountain and still pay less than Rhea would be 63.

Hello!
√28x³y³ is equal to [tex]2xy\sqrt{7xy}[/tex]
We can find this solution through the following steps.
Rewriting the equation by factoring 4 from 28, factoring out x², and factoring out y²We then can rewrite 4 as 2² in our equation, leaving us with [tex]\sqrt{2^{2}*7*(x^{2}x)*y^{2}y }[/tex]We will then move our x and 7, and rewrite [tex]2^{2}*x^{2}* y^{2}[/tex] as [tex](2xy)^{2}[/tex]We can then pull the terms from the radical leaving us with [tex]2xy\sqrt{7xy}[/tex]Please Fill in the Blank with the simplified equation. 5/8g=40
Multiply both sides by 8
5/8g × 8 = 40× 8

Which of the following is a true statement describing the pattern 20, 25, 30, 35,…? The pattern contains only even numbers. The pattern contains only odd numbers. The pattern is decreasing. The pattern contains only factors of 5.
In this pattern all are divisible by 5
20[tex] =4×5[/tex] i.e. divisible by 5
25[tex] = 5×5 [/tex] is divisible by 5
30[tex] =2×3×5[/tex] is divisible by 5
35[tex] =7×5 [/tex] is divisible by 5
Hence the pattern contain factor 5
The statement that correctly describes the pattern 20, 25, 30, 35, ... is that it contains only factors of 5.
The given sequence of numbers is 20, 25, 30, 35,... and the correct statement describing this pattern is that it contains only factors of 5. This is because each number in the sequence is a multiple of 5 and can be divided by 5 without leaving a remainder. The sequence is not exclusively even or odd numbers, as it contains both (20 and 30 are even, while 25 and 35 are odd). Also, the pattern is not decreasing; it is instead increasing by increments of 5.

what is 6 7/8 + 7 5/12
[tex]6 \: \frac{7}{8} \: + 7 \frac{5}{12} [/tex]
Here is your equation:
[tex]6 \frac{7}{8} + 7 \frac{5}{12}[/tex]
As you can see, the denominators, which is the bottom number in the fraction, are different. You need to have the same denominator, so that you can add it. To change the denominators, you need to find the LCM of both denominators, which is 8 and 12. To find the LCM, first list the multiples of both numbers and see what is common.
[tex]8 - 8, 16, 24, 32, 40, 48, 56 \\12-12, 24, 36, 48[/tex]
The only common number is 48. That means you need to change both fractions so that they have a denominator of 48.
[tex]6 \frac{7 \times 6}{8 \times 6} \rightarrow 6 \frac{49}{48}[/tex]
[tex]7 \frac{5 \times 4}{12 \times 4} \rightarrow 7 \frac{20}{48}[/tex]
Here is your new equation:
[tex]6 \frac{49}{56} + 7 \frac{20}{48}[/tex]
Add:
[tex]6 \frac{49}{48} + 7 \frac{20}{48} = 13 \frac{69}{48}[/tex]
Simplify:
[tex]13 \frac{69}{48} \rightarrow 14 \frac{21}{48} \rightarrow 14 \frac{7}{16}[/tex]
Your answer is 14 [tex]\frac{7}{16}[/tex]
