Answer:
C $1187
Step-by-step explanation:
diameter = 12ft
radius = 6 ft
area = πr²
= 3.14×6×6
= 113.04 ft²
paving stones is $10.5 per ft²
paving stones cost = 113.04×10.5 = 1186.92
; the nearest dollar do the paving stones cost is $1187
I am doing graphs but I'm struggling a lot with this
Answer:
Stem and Leaf Plot ⇒ Makes it easy to see the largest, smallest and most common data values.
Double Bar Graph ⇒ Compares two sets of data.
Bar Graph ⇒ Shows whether one type of data increases, decreases or neither when another type of data increases.
Scatter Plot ⇒ Shows the frequency of results and trends clearly.
Step-by-step explanation:
Stem and Leaf Plot makes a set of data easy to see and shows common data values together.
Double bar graph is the only graph that focuses solely on 2 sets of data.
Bar Graph description is a bit weird for this one to me but it's the last one (I did others first) and it is close enough.
Scatter plot is best at showing frequency and trends and to see the approximate increase/decrease of many data points.
The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.
Step-by-step explanation:
Let the athletes be 3x and 2x.
Now, By the question we get,
(3x-12)/(2x+12) = 5/4
or, 12x-48= 10x+60
or, 2x = 108
so, x = 54
now
3x= 3×54= 162
2x = 2×54=108
The number of athletes were 162 in first team and 108 in second team originally.
x is the number of athletes on first team originally ( x > 12, x ∈ Nˣ )
y ----------------------------------------second------------------( y ∈ Nˣ )
The ratio of athletes in the two teams is 3:2
⇒ [tex]\frac{x}{y} =\frac{3}{2}[/tex] (1)
After 12 athletes move from first team to second, the ratio is 5:4
⇒ [tex]\frac{x-12}{y+12} =\frac{5}{4}[/tex] (2)
(1),(2) ⇒ [tex]\left \{ {{\frac{x}{y} =\frac{3}{2}} \atop {\frac{x-12}{y+12} =\frac{5}{4}} \right. <=>\left \{ {{x=162} \atop {y=108}} \right.[/tex]
So: The first team originally has 162 numbers and the second team originally has 108 numbers
ok done. Thank to me :>

The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.
Answers:
team one = 162team two = 108=========================================================
Explanation:
The ratio 3:2 scales up to 3x:2x for some positive whole number x.
This tells us that the first team has 3x people and the second team has 2x people. We'll subtract 12 from the first team and add 12 to the second team to represent 12 people moving.
3x becomes 3x-122x becomes 2x+12The new team counts 3x-12 and 2x+12 represent team 1 and team 2. Those expressions are in the new proportion 5:4.
This means....
(team 1 new count)/(team 2 new count) = 5/4
(3x-12)/(2x+12) = 5/4
4(3x-12) = 5(2x+12)
12x-48 = 10x+60
12x-10x = 60+48
2x = 108
x = 108/2
x = 54
From this, we then can say:
team 1 original count = 3x = 3*54 = 162team 2 original count = 2x = 2*54 = 108The two subtotals add to 162+108 = 270 players overall.
If we were to subtract 12 from team 1, and add 12 to team 2, then,
team 1 new count = 162-12 = 150team 2 new count = 108+12 = 120The ratio 150:120 then reduces to 5:4 when we divide both parts by the GCF 30. This helps confirm we have the correct answer.
Answer:
162 athletes108 athletesStep-by-step explanation:
Each ratio can be expressed using two numbers that have the same sum. The sum in the first given ratio is 3+2 = 5, and in the second ratio, it is 5+4 = 9. The least common multiple of 5 and 9 is 45, so we can express both ratios so they have a sum of 45:
3 : 2 = 3(9) : 2(9) = 27 : 18
5 : 4 = 5(4) : 4(5) = 25 : 20
Here, we observe that the second ratio has numbers that look like 2 was moved from the numerator to the denominator. (27 -2 = 25; 18 +2 = 20) The problem statement tells us 12 athletes were moved, so multiplying the first ratio by 12/2 = 6 will tell us the numbers of players on each original team:
first team = 27×6 = 162 athletes
second team = 18×6 = 108 athletes
Delores has at most $500 for entertainment throughout the month. If she spends $45 per week on eating out and $25 each week on movies, what's the most amount she can spend on other entertainment throughout the month?
Answer:
The answer would be 280
Step-by-step explanation:
If there are about 4 weeks in each month and she eats out every week for 45 dollars.
45x4=180
and if she goes to the movies each week at 25 dollars do the same thing.
25x4=100
when you add the two sums together
180+100=280
finally you subtract 280 from the original number,
500-280=220
so delores would have 220 dollar left over for other activities.

Joan represents the height at which a sea gull is flying at +4 feet and the depth at which a fish is swimming at −3 feet on a number line, where 0 represents the surface of the water. Which of these explains whether the sea gull or the fish is closer to the surface of the water? The fish is closer to the surface of the water because |+4| = 4 and |−3| = 3, and 3 < 4. The fish is closer to the surface of the water because |+4| = 4 and − |−3| = −3, and −3 < 4. The sea gull is closer to the surface of the water because |+4| = −4 and |−3| = −3, and −3 > −4. The sea gull is closer to the surface of the water because |+4| = 4 and − |−3| = 3, and 4 > 3.
Answer:
The fish is closer to the surface of the water because |+4| = 4 and |−3| = 3, and 3 < 4.

A box of cereal states that there are 99 calories in a 3/4 cup serving. What is the unit rate for calories per cup? How many calories in 4 cups of cereal
Answer:
Hello There!
According to the question,
It is said that we have to find calories in 4 cups.
First we have to find in each cup.
So
[tex] \frac{3}{4} \times x = 99 \\ \\ so \: x = 99 \times \frac{4}{3} \\ \\ [/tex]
simplify 99 and 3 then it will look like
[tex]33 \times \frac{4}{1} [/tex]
1 has no value so 33×4=132 calories
Now it is in each cup or 1 cup.
To find in 4 cups, multiply 132×4
[tex]132 \times 4 = 528[/tex]
So 528 calories is the answer.
