Flowers - Samantha and Maria purchased flowers. Samantha bought five roses for "r" dollars each and four daises for "d" dollars each. Altogether, Samantha spent $32 on flowers. Maria purchased one rose for "r" dollars apiece and six daisies for "d" dollars apiece - spending $22 total.

a) Write a system of equations (two linear equations) using appropriate variables.

b) Solve the system to find the cost of roses and daisies. Use any strategy that you've learned.

Answers

Answer 1

Answer:

part a

[tex]5r + 4d = 32[/tex]

[tex]r + 6d = 22[/tex]

part b

the value of roses is 4 dollars a pieces and that of daisies is 3 bucks a piece

Step-by-step explanation:

part a

for part a just denote r for roses and rerecord the question in terms of a function of roses and daisies the right hand side should be the prices or cost

part b

solve the two equations simultaneously or by substitution.

let's do simultaneous

multiply the secondequation by 5

[tex]5r + 4d = 32[/tex]

[tex]5r + 30d = 110[/tex]

subtracting the two,

[tex]26d = 78[/tex]

therefore

[tex]d = 3 dollars[/tex]

find the value of roses,

[tex]5r + 4(3) = 32 \\ 5r = 32 - 12 \\ r = 4[/tex]

Suppose that Paul's checking account shows a balance of $725.35 at the beginning of the month. During this month,
he makes deposits of $472.25, $175.35, $194.50, and $317.85, and he writes checks for $150.30, $237.60,
$45.75, and $257.85. Find the end-of-the-month balance in his account.

Answers

Answer:

$ 1,193.80

Step-by-step explanation:

Balance + deposits =

725.35+472.25+175.35+194.50+317.85 = $ 1,885.30

$1,885.30 - withdrawals =

1885.30 - 150.30-237.60-45.75-257.85 = $ 1,193.80

The volume of a cube is found by:
1. l x w x h
2. l x w
3. w x h

Answers

Answer:

Step-by-step explanation:

l x w and w x h are all formula for a rectangle, not a cube.

For instance, let's take l x w. If we change the height it will definitely change the volume, but according to 2) it won't. So, 2 is wrong.

We can do the same process for 3) to show it's wrong.

So, the answer is not 2) or 3), so it must be [tex]\boxed{1)}[/tex]

what is the inverse of -9x+2

Answers

Step-by-step explanation:

so,

y = -9x + 2

now we need to transform this equation that actually x is calculated out of y.

and then, at the end, to make the inverse function a formally correct function, we rename x to y and y to x.

so,

y = -9x + 2

y - 2 = -9x

x = -(y - 2)/9 = (-y + 2)/9

=> for a formal function definition

y = (-x + 2)/9

3) MS. Thomton spends $1.44 on 6 ounces of Mike and lkes. How much does he spend for pound?
(16 oz = 1 lb).

Answers

Answer:

He spent $3.84 for a pound of Mike and Ikes.

Step-by-step explanation:

First thing to do is divide 1.44 by 6 to get the amount of $ 1 ounce of Mike and Ikes cost. 1.44/6=0.24

Then multiply 0.24 by 16(amount of ounces in a pound) to get the amount of $ spent on 1 pound of Mike and Ikes.

0.24*16=$3.84

what is the probability of rolling a product less than 5 on a pair of 6-sided dice

Answers

Answer:

2/3 probability

Step-by-step explanation:

less than 5 is 4. There are 6 sides, so its 4/6. 4 out of 6 simplifies to 2/3.

Answer:

as there are 2 six-sided dices so total cases = 6*6 = 36

products less than 5 are = (1,1) , (1, 2), (1, 3), (2,1), (2,2), (3,1)

so number of products less than 5 = 6

so the probability = 6/36 = 1/6

m < 105° and m < (10x + 15)° have the same measure because they are alternate interior angles that do not have a common vertex on alternate sides of the transversal. Since they have the same measure, we can solve for x:

m < 105° = m < 10x° + 15 °

Subtract 15 from both sides:

m < 105° - 15° = 10x°

90° = 10x°

Divide both sides by 10 to solve for x:

90°/10 = 10x/10

9° = x

Therefore, the value of x = 9°

Substitute this value into m < (10x + 15)° to find its true measure:

10(9) + 15 = 90 + 15 = 105°

This proves my statements earlier that m < 105° has the same measure as m < (10x + 15)°

The correct answer is x = 9°

a student sketched some art on an 8 inch x 10 inch piece if paper he wants to resize it to fit an 4 inch x 6 inch frame. What percent of the original sketch was still able to be included?

Answers

The picture is originally 11 inches wide by 8.5
inches tall. It gets scaled down to a new width of 7 inches. We need to find the new height. To do this, we write a proportion:

8.5/11=x/7

Cross multiply:
11x = 59.5

Divide:
X = 5.41

The size of the picture is 5.41" x7", but the size of the frame is 5" x7". The part of the picture's area that is included in the frame is:
(5 × 7) / (5.41 × 7)
= 5/ 5.41
= 0.924

92.4% of the picture is inside the frame.

Answer:

Step-by-step explanation:

Given, 5:3 = 5 to 3

1. 40/5 (40 divided by 5) 8

(You would divide to know what to do next.

You would also divide by the 5 because the ratio of the cars are red to blue, and the question asks if there were 40 red cars, how many blue cars were there.)

2. Because 5 red cars grouped into 8 were 40, multiply 3 by 8.

3. 3 x 8 = 24.
