Mrs. Traynor's class is taking a field trip to the zoo. The trip will cost $26 for each student. There are 22 students in her class. Part A Round each factor to estimate the total cost ofthe students' field trip. Part B Use compatible numbers to estimate the total cost of the field trip.
Answer:
Part A:The total cost can then be estimated as 20 × 30 = $600
Part B: Estimating the total cost with compatible number = 25 × 20 = $500
Step-by-step explanation:
Part A
Rounding off a number simply means making the number simpler but the rounded value should be close to the actual number. The number could be rounded to the nearest ten, hundred or thousand. The field trip to the zoo involved 22 student and the cost for each student is $26. The question ask to round each factor before estimating the total cost of the student's field trip. The number of student rounded to the nearest ten is 20 and the cost for each student rounded to the nearest ten is $30. The total cost can then be estimated as 20 × 30 = $600
Part B
Part B request we use compatible numbers to estimate the total cost of the field trip. Compatible numbers are numbers that are easy to calculate mentally. This pairs of numbers are easy to add, subtract, divide and multiply mentally. Using compatible numbers the cost can be 25 and the number of student can be 20. Estimating the total cost = 25 × 20 = $500
Note the actual total cost is 26 × 22 = $572

Step-by-step explanation:
According to law of conservation of mass :
In a balanced chemical equation, the mass of reactants is always equal to the mass of products.
Here, Water [tex]2H_{2}O[/tex] is the reactant which has 4 units of Hydrogen and 2 units of oxygen.
and [tex]2H_2+O_2[/tex] are products which also has 4 units 4 units of Hydrogen and 2 units of oxygen.
Thus, The mass of the reactants equals the mass of the products.
Thus, option (B) is correct.
What is the net force on this object? Small box with dot in the middle. Arrows originate at dot. Arrow up and Arrow down are same length. Arrow up labeled F sub norm equals 20 N and Arrow down labeled F sub grav equals 20 N. Arrow to the right is longer than arrow to the left. Arrow to the right is labeled F sub app equals 22 N and arrow to the left is labeled F sub frict equals 14 N. 0 newtons 8 newtons 22 newtons 36 newtons
Answer:
The net force is 8N.
Step-by-step explanation:
Consider the provided information.
Two forces cancel each other if they are in opposite direction and the forces are equal, the net force is zero in this case.
Now consider the figure 1:
Here, vertical forces (up and down) cancel each other and horizontal forces do not cancel each other, thus the force is unbalanced.
Calculate the net force as shown:
[tex]F_{net} = F_g + F_n + F_f + F_a[/tex]
Substitute [tex]F_g=-20, F_n=20, F_f =-14, F_a=22[/tex] in above formula.
[tex]F_{net}= -20 + 20 -14 + 22 = 8 N[/tex]
Hence, the net force is 8N.

Zuma bought a snowboard with a regular price of $295. It was on sale at a 25% discount. There was an 8% tax on sale price. How much did Zuma spend to buy the snowboard?
To calculate the total amount Zuma spent on a snowboard, first determine the sale price by subtracting the discount from the original price, then add the sales tax to the sale price. Zuma spent a total of $238.95 on the snowboard after a 25% discount and an additional 8% sales tax.
Explanation:To find out how much Zuma spent to buy the snowboard, we have to first calculate the discounted price of the snowboard and then add the sales tax to it.
Step 1: Calculate the discount amount by multiplying the original price by the discount rate in decimal form.
Discount = Original Price × Discount Rate
Discount = $295 × 0.25 = $73.75
Step 2: To find the sale price, subtract the discount amount from the original price.
Sale Price = Original Price - Discount
Sale Price = $295 - $73.75 = $221.25
Step 3: Calculate the sales tax by multiplying the sale price by the tax rate in decimal form.
Sales Tax = Sale Price × Tax Rate
Sales Tax = $221.25 × 0.08 = $17.70
Step 4: To find the total amount spent, add the sales tax to the sale price.
Total Spent = Sale Price + Sales Tax
Total Spent = $221.25 + $17.70 = $238.95
Zuma spent $238.95 to buy the snowboard.

Answer:
Sample Response: Divide the number of hits, 102, by the times at bat, 300. Then move the decimal 2 places to the right and add the percent sign to get 34%.
Step-by-step explanation:
Sample Response: Divide the number of hits, 102, by the times at bat, 300. Then move the decimal 2 places to the right and add the percent sign to get 34%.
The percent of times the baseball player got a hit out of the number of times at bat will be 34%.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
A baseball player got 102 hits in the last 300 times at bat.
Then the percent of times the baseball player got a hit out of the number of times at bat will be
P = (102 / 300) x 100
P = 0.34 x 100
P = 34%
The percent of times the baseball player got a hit out of the number of times at bat will be 34%.

mr.young has 30 times as many pencils as jack. the whole school has 200 times as many pencils as jack. if jack has 2 pencils, how many pencils does mr. young have?how many pencils does the whole school have?
Final answer:
Mr. Young has 60 pencils, and the whole school has 400 pencils, calculated by multiplying Jack's 2 pencils by 30 and 200 respectively.
Explanation:
Mr. Young has 30 times as many pencils as Jack. If Jack has 2 pencils, then to find out how many pencils Mr. Young has, we simply multiply Jack's number of pencils by 30:
Mr. Young's pencils = Jack's pencils × 30
Mr. Young's pencils = 2 × 30 = 60 pencils.
Similarly, the whole school has 200 times as many pencils as Jack. To find out how many pencils the whole school has, we multiply Jack's number of pencils by 200:
The whole school's pencils = Jack's pencils × 200
The whole school's pencils = 2 × 200 = 400 pencils.
