Answer:
15 windflower bulbs
19 daffodil bulbs
Step-by-step explanation:
Given
Represent windflower with W and daffodil with D.
So:
Mary's sales is:
10W + 4D = 226 --- (1)
Darryl's sales is:
6W + 4D = 166 ---- (2)
Required
Solve for W and D
We'll make use of elimination method.
Start by subtracting (2) from (1)
10W - 6W + 4D - 4D = 226 - 166
4W = 60
Multiply both sides by ¼
¼ * 4W = 60 * ¼
W = 60 * ¼
W = 15
Substitute 15 for W in (1)
10W + 4D = 226
10 * 15 + 4D = 226
150 + 4D = 226
Collect like terms
4D = 226 - 150
4D = 76
Multiply both sides by ¼.
¼ * 4D = 76 * ¼.
D = 19

A soccer player uses her head to hit a ball up in the air from a height of 2 meters with an initial vertical velocity of 5 meters per second. The height h in meters of the ball is given by \large h=-4.9t^2+5t+2 , where t is the time elapsed in seconds. How long will it take the ball to hit the ground if no other players touch it?
Answer:1.32 s
Step-by-step explanation:
Given
The initial height of ball H=2 m
Initial velocity u=5 m/s
Height of ball at any instant is given by
[tex]H=-4.9t^2+5t+2[/tex]
The ball will hit the ground when h=0
[tex]-4.9t^2+5t+2=0\\4.9t^2-5t-2=0\\t=\dfrac{5\pm\sqrt{25+4(4.9)(2)}}{2\times 4.9}\\t=\dfrac{5\pm\sqrt{64.2}}{9.8}\\t=\dfrac{5+8.01}{9.8}=1.32\ s\quad\text{Neglecting negative value of t}[/tex]
A market research survey has 15 questions and will be sent to 500 people. What is the total cost to conduct the survey if it has a $1,000 base fee plus $5 per question and $2 per person surveyed?
Answer:
Total cost to conduct survey = $2075
Step-by-step explanation:
Given that:
Number of questions on survey = 15
Number of people = 500
Base fee = $1000
Per question charge = $5
Per person surveyed = $2
Let,
q be the number of questions
p be the number of people
Total cost = Base fee + 5q + 2p
Total cost = 1000 + 5(15) + 2(500)
Total cost = 1000 + 75 + 1000
Total cost = $2075
Hence,
Total cost to conduct survey = $2075

Answer:
$88
Step-by-step explanation:
first, you find 20% of 57 which = 11.4
then subract it with 57 which looks like 57-11.4 = 45.6
= 45.6
first, you find 20% of 53 which = 10.6
then subract it with 53 which looks like 53-10.6 = 42.7
= 42.4
then you add them both which = 45.6+ 42.4= 88

Sara sold 461 tickets for a school play. Student tickets cost $3 and adult tickets cost $4. Sara’s sales totaled $1624.How many adult tickets and how many student tickets did Sara sell?
Answer:
220 student and 241 adults
Step-by-step explanation:
x+y=461
3x+4y=1624
y=-x+461-----> 3x+4(-x+461)=1624
-x+1844=1624
+x -1624
x=220
3(220)+4y=1624
660+4y=1624
4y=964
y=241
There are 241 adult tickets and 220 student tickets did Sara sell.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Sara sold 461 tickets for a school play.
And, Student tickets cost $3 and adult tickets cost $4. Sara’s sales totaled $1624.
Let number of adult tickets = x
And, Number of student tickets = y
Hence, We get;
⇒ x + y = 461 .. (i)
And, 4x + 3y = 1624 .. (i)
Multiply by 3 in (i);
⇒ 3x + 3y = 1383 .. (iii)
Subtract form (ii);
⇒ x = 241
And, From (i);
⇒ x + y = 461
⇒ 241 + y = 461
⇒ y = 461 - 241
⇒ y = 220
Thus, There are 241 adult tickets and 220 student tickets did Sara sell.

I don´t get how to solve it please explain
Answer:
B. 16.9
Step-by-step explanation:
Reverse Pythagoreans theorem C^2 - B^2 = A^2 so
7^2 - 5^2 = c^2 and it comes out to
49-25 = 24 the square root of that is 4.9 (rounded)
But we are lookign for the perimeter so
4.9 + 7 + 5 = 16.9
Edith leaves her home at 11:50 am.
She travels 75 miles at an average speed of 30 mph.
At what time does she finish the journey.
Answer:
2:30 minutes her journey finish.
distance / speed = time
75 / 30 = 2.5 hours :
it means 2:20 pm they finish her journey
Step-by-step explanation:
Brainliest?
Answer:
2:20 pm
Step-by-step explanation:
30 mph=1 mile every 2 minutes
75 miles x 2 =150 minutes or 2 hours and 30 minutes
11:50 am + 2 hours and 30 minutes = 2:20 pm
Using the formula Distance = rate . time, find the distance covered by an airplane flying at 300 mph for 3 hours.

I need help in this
Answer:
x = 4
Step-by-step explanation:
Since the rectangles are similar, use a ratio.
15/6 = 10/x
or
6/15 = x/10
I will use 15/6 = 10/x to solve this problem, but both ratios should work to solve this problem.
15/6 = 10/x
Cross Multiply:
6(10) = 15x
Solve:
60 = 15x
x = 4

Help pleasee! Thank uu
Answer:
The answer is the 2nd option
Step-by-step explanation:
Bryan and Yuan started out at their houses and are biking towards each other. Bryan started
out first, and has already gone 5 miles. He bikes at a constant speed of 3 miles per hour.
Yuan just left, and rides at 4 miles per hour. When the boys meet halfway between their
houses, they will continue to the park together. How long will that take? How far will each
boy have ridden?
Answer:
Bryan and Yuan will meet after 5 hours, having traveled 20 miles each.
Step-by-step explanation:
Given that Bryan and Yuan left their homes at different periods of time and at different speeds, to determine how long they will meet and how much distance they will have traveled, the following calculation must be performed:
B = 5 + (3X)
Y = 4X
B = 5 + 3x2 = 11
Y = 4x2 = 8
B = 5 + 3x3 = 14
Y = 4x3 = 12
B = 5 + 3x4 = 17
Y = 4x4 = 16
B = 5 + 3x5 = 20
Y = 4x5 = 20
Therefore, Bryan and Yuan will meet after 5 hours, having traveled 20 miles each.

Let x denote the number of broken pencils in a randomly selected 50-count box from a local office supply store. The variable x has the
following probability distribution:
a)
0.82; if we were to select many boxes of pencils randomly, the number of broken pencils would typically vary about 0.82 from the
mean
b)
0.31; if we were to select many boxes of pencils randomly, we would expect about 0.31, on average, to contain broken pencils
c)
0.65; if we were to select many boxes of pencils randomly, the number of broken pencils would typically vary about 0.65 from the
mean
d)
0.52; if we were to select many boxes of pencils randomly, we would expect about 0.52 to have no broken pencils
e)0.13; if we were to select many boxes of pencils randomly, we would expect about 0.13, on average, to contain broken pencils

I need help solving the equal method
Answer:
(-2, -4)
Step-by-step explanation:
Since both equations are equal to y, you can set them equal to each other:
[tex]\frac{3}{2}x-1=\frac{1}{2}x-3[/tex]
Next, solve for x:
[tex]\frac{3}{2}x-1=\frac{1}{2}x-3\\x-1=-3\\x=-2[/tex]
Finally, substitute the solution for x in one of the equations (or both) to find y:
[tex]y=\frac{3}{2}(-2)-1\\y=-3-1\\y=-4[/tex]
[tex]y=\frac{1}{2}(-2)-3\\y=-1-3\\y=-4[/tex]
Therefore, the solution to the system of equations is (-2, -4).
