The sparrow's heart beats approximately 158 times faster than a human heart. None of the options provided (A, B, C, or D) match this calculation.
Explanation:To find how many times faster the sparrow's heartbeat is compared to the human heart, you divide the number of times the sparrow's heart beats by the number of times a human heart beats. Thus, you would perform 241,776,000 ÷ 1,533,000. The result of this division is approximately 157.7, which means that the sparrow's heart beats about 158 times faster than a human heart.
None of the options provided in the question (A, B, C, or D) match this result, indicating there may be a mistake. Always remember, the correct way to compare in such circumstances is to do division, and not multiplication or addition.

Marcia buys a dress that is on sale for 15% off it's original price. She uses a store coupon to obtain an additional 10% off the sale price. Marcia pays $91.80 for the dress. What was the original price of the dress?
Answer:
120$
Step-by-step explanation:
We must calculate the prices with the application of discounts successively
The last discount he got was 10%, so $ 91.80 equals 90% of the price
We calculate the price before this discount by applying with a simple rule of three
[tex]90 \% \longrightarrow 91.80\\100\% \longrightarrow x\\x=\frac{(100)(91.80)}{90}\\ x= 102\$[/tex]
She pays $ 102 with a 15% discount, so this value equals 85% of the original price
We calculate the price before this discount by applying with a simple rule of three
[tex]85\% \longrightarrow 102\\100\% \longrightarrow x\\x=\frac{(100)(102)}{85}\\ x= 120\$[/tex]
please help Graph y= –3x+4 .
The graph of the equation of line y = -3x + 4 is plotted
Given data ,
Let the equation of line be represented as A
Now , the value of A is
y = -3x + 4
where the equation is in the form of slope intercept
where the y-intercept is given by b = 4
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = -3
So , the slope of -3 indicates that for every 1 unit increase in x, the value of y decreases by 3 units. The negative slope means that the line is decreasing as x increases, sloping downward from left to right.
Hence , the equation of line is plotted on the graph

Sophie and Eleanor are making bouquets using daisies and tulips. Each bouquet will have the same total number of flowers,Eleanor uses fewer daisies in her bouquet. than sophie. Whose bouquet will have the greatet ratio of daisies of total flowers? Explain.
Answer:
Sophie's ratio is greater.
Step-by-step explanation:
Sophie and Eleanor are making bouquets using daisies and tulips. Each bouquet will have the same total number of flowers.
Eleanor uses fewer daisies in her bouquet than Sophie.
Lets say the total flowers used in each bouquet is 15.
Eleanor uses 5 daisies. So, her ratio for daisies to total flowers become = [tex]\frac{5}{15}=\frac{1}{3}[/tex]
Suppose Sophie uses 10 daisies so her ratio becomes = [tex]\frac{10}{15}=\frac{2}{3}[/tex]
Now comparing both ratios, we can see that Sophie's ratio is greater.

B) Nick ran 12.8 miles less than Perry last week. If Nick ran 9.2 miles, how many miles did Perry run? C) Perry ran 9.2 miles less than Perry last week. If Nick ran 12.8 miles, how many miles did Perry run? D) Nick ran 9.2 miles less than Perry last week. If Nick ran 12.8 miles, how many miles did Perry run?
The correct answer is D
Nick ran 9.2 miles less than Perry last week. If Nick ran 12.8 miles, how many miles did Perry run?
x - 9.2 = 12.8
x = 12.8 + 9.2
x = 22
Perry ran 22 miles for the week, 9.2 miles more than Nick.

Sean and his sister, Betty equally mow 8/9th the total area of a lawn. What fraction of the total area did each of them mow? (Show ur work plz)
Using the division operation, the fraction of the total area mowed by each person is [tex] \frac{4}{9}[/tex]
Total fraction mowed = [tex] \frac{8}{9}[/tex]
Number of persons who mowed the area = 2
Since, the same amount of area ws mowed by each person, then the area mowed per person can be calculated thus :
Total Area mowed ÷ number of persons[tex] \frac{48}{9} \div 2 = \frac{4}{9}[/tex]

The manager of a plant nursery bought 120 lb of soil to use for potting plants. The manager can put 5 lb into each of the small pots and 12 lb into each of the large pots. The manager made a sketch to show the line representing the different combinations of pots that can be used. The x-axis represented the number of small pots and the y-axis represented the number of large pots. The manager labeled only the intercepts.
Which points did the manager label?
1. (0, 12) and (5, 0)
2. (0, 10) and (24, 0)
3. (0, 24) and (10, 0)
4. (0, 5) and (12, 0)
The points that were labelled by the manager on the graph are (0, 10) and (24, 0). These points are found by dividing the total amount of soil by the amount of soil required by each type of pot.
Explanation:In this Mathematics problem, we need to determine which points were labelled on the graph created by the nursery manager representing combinations of small and large pots. We can find these points, the intercepts, by understanding that these occur when one variable is zero. The x-intercepts happen when all soil is used for large pots (i.e., the y-axis, or number of small pots, is zero), and the y-intercepts occur when all the soil is used for small pots (i.e., the x-axis, or number of large pots, is zero). For the x-intercept, if each large pot requires 12lb of soil, then the manager could fill 120/12 = 10 large pots if no soil is used for small pots. Therefore, the x-intercept is (0, 10). Similarly, the y-intercept would be obtained by dividing the total amount of soil with the amount used for a small pot. That gives us 120/5 = 24. Hence, the y-intercept is (24, 0). So, the points labelled by the manager are option 2: (0, 10) and (24, 0).
