Answer:
part a[tex]5r + 4d = 32[/tex]
[tex]r + 6d = 22[/tex]
part bthe value of roses is 4 dollars a pieces and that of daisies is 3 bucks a piece
Step-by-step explanation:
part afor 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 bsolve 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]
MIDDLE SCHOOL MATH On the subway 8 out of 10 people are carrying a briefcase. Based on this information, if there are 700 people on the subway, then about how many do NOT have a briefcase?
Answer:
140
Step-by-step explanation:
If 8 out of 10 are carrying a briefcase, that means 2 out of 10 are not carrying one.
Use a proportion to find how many don't have a briefcase with 700 people
Let x represent the number of people without a briefcase:
[tex]\frac{2}{10}[/tex] = [tex]\frac{x}{700}[/tex]
Cross multiply and solve for x
10x = 1400
x = 140
So, 140 people do not have a briefcase
Answer:
140
Step-by-step explanation:
8/10 people, there's 700 people
10 multiplied by 70 =700.
2 people dont have briefcases = 2 times 70=140
Find the exact (leave pi) and the approximate ( pi = 3.14 ) circumference for each circle
(#s A-F ONLY)
Answer/Step-by-step explanation:
a. Circumference (C) = πd
d = 12 cm
π = 3.14
Exact value of C = π*12 = 12π cm
Approximate value of C = 12*3.14 = 37.68 cm
b. Circumference (C) = πd
d = 8 m
π = 3.14
Exact value of C = π*8 = 8π m
Approximate value of C = 8*3.14 = 25.12 m
c. Circumference (C) = πd
d = 6 km
π = 3.14
Exact value of C = π*6 = 6π km
Approximate value of C = 6*3.14 = 18.84 km
d. Circumference = πd
d = 9 ft
π = 22/7
Exact value of C = π*9 = 9π ft
Approximate value of C = 9*22/7 = 28.2857143 ≈ 28.29 ft (nearest hundredth)
e. Circumference = 2πr
r = 4 mm
π = 22/7
Exact value of C = 2*π*4 = 8π mm
Approximate value of C = 2*22/7*4 = 25.1428571 ≈ 25.14 mm (nearest hundredth)
f. Circumference = 2πr
r = 7 mi
π = 22/7
Exact value of C = 2*π*7 = 14π mi
Approximate value of C = 2*22/7*7 = 44 mi (nearest hundredth)

Step-by-step explanation:
A cable TV/Internet/phone provider charges new customers $90 for all three services, per month, for the first year
under their 90 NOW promotion. Alice normally pays $59 for her monthly home phone service, $49 for Internet
service, and $69 for cable television
1. What are her percent savings if she switches to the 90 NOW plan? Round to the nearest percent.
Answer:
49%
Step-by-step explanation:
First find how much Alice is paying for the all three service currently.
Amount paid by Alice at present= 59 + 49 + 69 = $ 177
If she switches to 90 NOW plan, then the amount saved = 177 - 90 = $ 87
Percentage of savings = (saved amount ÷ total amount she was paying at present) * 100
[tex]= \frac{87}{177}* 100\\\\= 49.15[/tex]
= 49 %

Step-by-step explanation:
A circular mirror has a diameter of 12 inches. And a circular frame that is 3 inches wide surrounds the mirror. What is the combined area, in square inches, of the circular mirror and the frame? *
Answer:
254.5 in.^2
Step-by-step explanation:
diameter of mirror = 12 in.
radius of mirror = diameter/2 = 13 in. / 2 = 6 in.
frame width = 3 in.
radius if combined mirror and frame = 6 in. + 3 in. = 9 in.
A = (pi)(r^2)
A = 3.14159 * (9 in.)^2
A = 3.14159 * 81 in.^2
A = 254.5 in.^2

Write the equation in standard form, then identify center and radius of circle.
Answer:
Step-by-step explanation:
Given
x^2 + y^2 - 16y - 36 = 0
x^2 + y^2 - 16y = 36
x^2 + y^2 - 16y + (16/2)^2 = 36 + 8^2
x^2 + (y - 8)^2 = 64 + 36
x^2 + (y - 8)^2 = 100
The center is at (0,8) and the radius is 10

Ms. Jaffey had a total of 428.5 ounces of pretzels to put into 5 bowls for a party. She put an equal number of ounces of pretzels into each bowl. How many ounces of pretzels did Ms. Jaffey put into each bowl?
Ms. Jaffey put approximately 85.7 ounces of pretzels into each bowl.
To find out how many ounces of pretzels Ms. Jaffey put into each bowl, we need to divide the total number of ounces by the number of bowls.
Ms. Jaffey had a total of 428.5 ounces of pretzels, and she distributed them equally among 5 bowls. Therefore, we can divide the total number of ounces by 5 to determine the amount in each bowl.
428.5 ounces ÷ 5 bowls = 85.7 ounces.
So, Ms. Jaffey put approximately 85.7 ounces of pretzels into each bowl.
Since it's unlikely to have exact measurements when dividing a total quantity into equal parts, we round the result to one decimal place, giving us 85.7 ounces. This means that each bowl contains approximately 85.7 ounces of pretzels.

A fair number cube and a spinner are used in a game. The faces of the number
cube are labeled 1 through 6. The spinner has an equal chance of landing on 1 of 5
colors: red, green, blue, yellow or black. What is the probability of a player rolling an
even number and then spinning green?
Answer:
1 /10
Step-by-step explanation:
Fair cube ; numbered (1 - 6)
Spinner ; (red, green, blue, yellow or black)
Even numbers = (2, 4, 6)
Probability of obtaining an even number on rollin g a fair cube :
Probability = required outcome / Total possible outcomes
P(even number) = 3 /6 = 1/2
P(green color on spinner) = 1 /5
P(even number and green color) = 1/2 * 1/5 = 1/10

What is the unit rate for the ratio 4/7: 8/21?
Answer:
The unit rate is 1.5
Step-by-step explanation:
Given
[tex]Ratio = 4/7 : 8/21[/tex]
Required
Determine the unit rate
To do this, we need to express the ratio as:
[tex]Ratio = m : 1[/tex]
Where m is the unit rate
[tex]Ratio = 4/7 : 8/21[/tex]
Express as fraction
[tex]Ratio = \frac{4/7 }{ 8/21}[/tex]
Solve
[tex]Ratio = \frac{4}{7} * \frac{21}{8}[/tex]
[tex]Ratio = 1.5[/tex]
Express as ratio
[tex]Ratio = 1.5 : 1[/tex]
Hence, the unit rate is 1.5
