Answers

Sophie will have a greater daises to total flowers ratio than Eleanor. To make this easier to see, let's assume the boquets have 10 flowers each, and Eleanor uses 2 daisies and 8 tulips, while Sophie uses 5 daisies and 5 tulips. Then Eleanors ratio is 2:10=1:5, while Sophie's ratio is 5:10=1:2.

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.

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?

Answers

15% off the original price
10% off the sale price
Sale price $91.80 

First we have to find out the price before 10% discount. 
(sale price) divided by (1 - percent of sale price)

91.80/(1 -.10) = $102

So, $102 was the price before the 10% discount. Now we need to do the same with the 15% off so that we can get the original price.

102/(1 - .15) = $120 

The original price was $120

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 .

Answers

First start at the point 0,4 because the positive is our y-intercept. Then go up three over one to the left till you reach the end of the graph, then go back to 0,4.
Then go 3 down and right one till you reach the end of the graph. And now you got a line!
Y=mx+b
m=slope  (-3)
b=y-intercept   (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

Which graph represents the equation y=13x−4 ?

Answers

Answer:  The correct option is graph (A).

Step-by-step explanation:  We are given to select the graph that represents the following linear equation :

[tex]y=\dfrac{1}{3}x-4~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

Comparing with the slope-intercept form y = mx + c of a straight line, we see that

the slope of the line (i) is [tex]m=\dfrac{1}{3},[/tex] and y-intercept, c = -4.

Also, we know that the slope of a line passing through the points (a, b) and (c, d) is given by

[tex]m=\dfrac{d-b}{c-a}.[/tex]

Graph (A) :  

The points (0, -4) and (3, -3) lies on the line. So, its slope will be

[tex]m=\dfrac{-3-(-4)}{3-0}=\dfrac{1}{3},[/tex]

the point where the line crosses the y-axis is (0, -4).

That is, y-intercept, c = -4.

Since the slope and y-intercept of graph (A) is same as that of line (i), so this option is CORRECT.

Graph (B) :  

The points (0, -2) and (3, -3) lies on the line. So, its slope will be

[tex]m=\dfrac{-3-(-2)}{3-0}=-\dfrac{1}{3},[/tex]

Since the slope of graph (B) is not same as that of line (i), so this option is NOT CORRECT.

Graph (C) :  

The points (0, -4) and (-3, 3) lies on the line. So, its slope will be

[tex]m=\dfrac{3-(-4)}{-3-0}=-\dfrac{7}{3},[/tex]

Since the slope of graph (C) is not same as that of line (i), so this option is NOT CORRECT.

Graph (D) :  

The points (-4, 0) and (-3, 3) lies on the line. So, its slope will be

[tex]m=\dfrac{3-0}{-3-(-4)}=\dfrac{3}{1}=3,[/tex]

Since the slope of graph (B) is not same as that of line (i), so this option is NOT CORRECT.

Thus, graph (A) is the correct option.

Step-by-step explanation:

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)

Answers

The intercept are the number of each of the pots used when no soil was put in the other pot.
When no soil was put in the large pots, then 120/5 = 24 small pots will be filled.
When no soil was put in the small pots, then 120/12 = 10 large pots will be filled.

THerefore, the points labelled are (24, 0) and (0, 10)
Final answer:

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).

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)

Answers

Since they mowed [tex]\frac{8}{9}[/tex] of the lawn in two equal parts, we need to split the pieces that were mowed into two equal groups. We know that in total they mowed 8 out of the total 9 pieces of lawn, so two equal groups that make 8 would be of size 4, since [tex]\frac{8}{2}=4[/tex]. Then they each mowed [tex]\frac{4}{9}[/tex] of the lawn.

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]

Hence, each person mowed [tex] \frac{4}{9}[/tex]
