Holly missed 8 of 182 school days this year. Approximately what percent of school days was Holly in attendance?
Answer:
Wrong it is
Step-by-step explanation:
First, determine how many school days Holly attended.
182 - 7 = 175
Next, find the percentage of school days she attended.
175 ÷ 182 = 0.9615384615 96%
Holly attended approximately 96% of school days.
To calculate the percentage of school days Holly was in attendance, subtract the days missed from the total days and divide by the total days, then multiply by 100.
Holly missed 8 out of 182 school days this year. To find the percentage of days she was present, subtract the days missed from total days and divide by total days, then multiply by 100.
Days attended = 182 - 8 = 174Percentage attended = (174/182) * 100 ≈ 95.60%z - y-1/3 if y=4 and z=3
What is the approximate length of the midsegment parallel to BC. the coordinates are B(-6,1) C(5,-1) ? please help
Step-by-step explanation:
Let the mid-point of BC is M. So, the length of BM = MC.
The coordinates of B are (-6, 1) and coordinates of C are (5, -1). Therefore, using the distance formula find the distance as follows.
d = [tex]\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}[/tex]
Place the values form points B and C into the above formula as follows.
d = [tex]\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}[/tex]
= [tex]\sqrt{(5- (-6))^{2} + ((-1)- (1))^{2}}[/tex]
= [tex]\sqrt{(11)^{2} + (-2)^{2}}[/tex]
= [tex]\sqrt{121 + 4}[/tex]
= [tex]\sqrt{125}[/tex]
= 11.18 (approx)
Therefore, the length of mid-point of line segment will be [tex]\frac{11.18}{2}[/tex] = 5.59 (approx). BM = MC = 5.59.
The length of line segment which is parallel to BC = [tex]\frac{d}{2}[/tex].

Use doubles minus one to solve 8+7. Write the number sentence
Answer:
8+8-1 = 15
Step-by-step explanation:
The doubles minus one is the technique to add two numbers which are consecutive.In this technique you add double the greatest number of the two consecutive and then subtract 1 from the result.
Here we have equation 8+7.
so doubling the greater number (8+8) or (8*2) gives us 16.
then subtracting 1 from it (16-1) gives us 15
so 15 is our answer.
Using the doubles minus one strategy, the greater value of the expression is doubled and one subtracted from the sum. Hence, we have 8 + 8 - 1 = 15
Given the expression :
8 + 7
The greater value of the two digits is 8
Doubling the greater value : 8 + 8
Subtracting 1 from the sum of the doubled digit :
8 + 8 - 1 = 8 - 7 = 15
Therefore, the result of the expression is 15

A line with a slope of 1/2 passes through the point 2,-1 what is the equation of this line
The equation of the line is [tex]\( y = \frac{1}{2}x - 2 \)[/tex].
To find the equation of a line with a given slope passing through a specific point, you can use the point-slope form of a linear equation: [tex]\( y - y_1 = m(x - x_1) \)[/tex], where ( m ) is the slope and [tex]\( (x_1, y_1) \)[/tex] is the given point.
Given that the slope [tex]\( m = \frac{1}{2} \)[/tex] and the point ( (2, -1) ), we substitute these values into the point-slope form:
[tex]\( y - (-1) = \frac{1}{2}(x - 2) \)[/tex]
This simplifies to:
[tex]\( y + 1 = \frac{1}{2}(x - 2) \)[/tex]
To remove the fraction, distribute [tex]\( \frac{1}{2} \)[/tex]:
[tex]\( y + 1 = \frac{1}{2}x - 1 \)[/tex]
Now, isolate ( y ) by subtracting 1 from both sides:
[tex]\( y = \frac{1}{2}x - 1 - 1 \)[/tex]
[tex]\( y = \frac{1}{2}x - 2 \)[/tex]
So, the equation of the line is [tex]\( y = \frac{1}{2}x - 2 \)[/tex].
A container holds 3 quarts of lemonade. How much is this in cups? Use the table below. Include the correct unit in your answer.
To find out how many cups are in 3 quarts of lemonade, you multiply the number of quarts (3) by the conversion factor of 4 cups per quart, giving you 12 cups of lemonade.
To answer the question, 3 quarts of lemonade is equivalent to how many cups, we will need to use the conversion between quarts and cups. In the United States customary system, 1 quart is equal to 4 cups. Therefore, to convert quarts to cups, you would multiply the number of quarts by 4.
To solve:
Multiply the number of quarts by 4 to convert to cups.Thus, 3 quarts of lemonade is equivalent to 12 cups of lemonade.

Answer: $ 0.41
Step-by-step explanation:
Given : The Factors shot 5 rolls of film with 36 exposures on each roll.
i.e. One roll contains 36 exposures .
It cost $14.85 to process each roll.
Then, the cost to process each exposure will be :_
[tex]\$14.85\div36=\$0.4125\\\\\approx\$0.41\ \ \ \ [\text{ Rounded to the nearest penny}][/tex]
Therefore, the cost to process each exposure= $0.41
Find the product. 7 times 300= 7 x blank hundreds
Final answer:
The product of 7 times 300 is 2100, which can be expressed as 7 times 21 hundreds when considering that 300 equals 3 hundreds.
Explanation:
The student asked to find the product of 7 times 300, which can be represented algebraically as 7 × 300. To express this in terms of hundreds, we would have 7 × 3 hundreds, since 300 is the same as 3 hundreds. Following the multiplication of 7 and 3, we get 21 hundreds, which is equal to 2100. Therefore, the completed statement would be 7 × 300 = 7 × 21 hundreds.
This multiplication utilizes the concept where multiplying by a power of ten, like hundreds (102), is equivalent to moving the decimal point to the right in this case by two places.
roland sold 26 candy bars during the first week. the number of candy bars he sold during the second week was 4 less than 2 times the number of candy bars he sold during the first week. the number of candy bars he sold during the third week was 6 more than 1 1/2 times the number of candy bars he sold during the second week. what was the total number of candy bars roland sold during the three weeks?
The number of candy bars Roland sold during the three weeks will be 152.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
Roland sold 26 candy bars during the first week.
The number of treats he sold during the subsequent week was 4 under twice the quantity of pieces of candy he sold during the principal week.
Then the number of candies sold in the second week will be calculated as,
⇒ 2 x 26 - 4
⇒ 48
The number of sweet treats he sold during the third week was 6 a greater number than 1 ¹/₂ time the number of pieces of candy he sold during the subsequent week. Then the number of candies sold in third week will be given as,
⇒ 48 x (1 ¹/₂) + 6
⇒ 48 x 1.5 + 6
⇒ 72 + 6
⇒ 78
The total candies are calculated as,
⇒ 26 + 48 + 78
⇒ 152
The number of candy bars Roland sold during the three weeks will be 152.
