On Saturday, many tickets fir a hockey game were sold. Children and adult were in the ratio of 4:7. There are 88 tickets in total. How many adult tickets were sold?
Answer:
56 adult tickets were sold
Step-by-step explanation:
Ratio of ticket sold to Children and adult is in the ratio 4 : 7
Total ratio = 4 +7 = 11
Ratio of adult = 7
Total ticket sold = 88
Number of adult tickets sold = Ratio of adult/Total ratio * Total ticket sold
Number of adult tickets sold = 7/11 * 88
Number of adult tickets sold = 7 * 8
Number of adult tickets sold = 56 tickets
Hence 56 adult tickets were sold
Each polio vaccination consists of 4 doses, and each measles vaccination consists of 2 doses. Last year, Dr. Potter gave a total of 606060 vaccinations that consisted of a total of 184 doses. How many polio vaccinations and how many measles vaccinations did Dr. Potter give last year?
I think there is a little error in your question. I guess You mean 60 vaccinations instead of 606060. I solved using 60 vaccinations.
Answer:Dr. Potter gave 32 polio vaccines and 28 measles vaccinations that year.
Step-by-step explanation:
STEP 1
Let number of polio vaccines be x
and number of measles vaccine be y
such that
total does of 60 vaccinations be expressed as
x+y = 60---- equation 1
And number of doses for both vaccine to total 184 doses taken be expressed as
4x + 2y= 184 ---- equation 2
Step 2--- solving
x+y = 60---- equation 1
4x + 2y= 184 ---- equation 2
Making x the subject of formula in equation 1 and substituting it in equation 2
x= 60-y
4(60-y) +2y- 184
240-4y+2y=184
240-184= 4y-3y
56= 2y
y= 58/2 = 28
To get x , put the value of y=28 in equation 1 and solve
x+y=60
x=60-28
x=32
Therefore Dr. Potter gave 32 polio vaccines and 28 measles vaccinations that year.

At a football game, you bought
x hot dogs for $2.50 each and x candy bars
for $1.50 each. If admission cost $8.50,
write an expression in simplest form that
represents the total spent at the game.
Answer:
[tex]y=4x+8.5[/tex]
Step-by-step explanation:
[tex]b=8.5[/tex] the initial cost is $8.5
[tex]m=2.5+1.5[/tex] the price changes by $4 for every hotdog & candy bar purchased
The final equation is [tex]y=4x+8.5[/tex]
Answer:
$12.00
Step-by-step explanation:
$8.50 + $2.50 = $10.00 + $1.50 = total $12.00

compare the graph of g(x)=6x−5 to the graph of f(x)=6x
a. g(x) shifted up 5 units
b. g(x) shifted down 5 units
c. g(x) is 6 units steeper
d. f(x) shifted down 5 units
Answer:
D
Step-by-step explanation:
Here, we want to compare the graph of g(x) and f(x)
Looking at the given equations, the difference between the two is that we have 5 subtracted from one of the equations
What this means is that we are moving down 5 units away from the graph of f(x) to get the graph of g(x)
Thus, option D is the correct answer
The golden ratio is a solution to a quadratic equation.
a. Find the precise value for Φ by solving Φ2 − Φ − 1 = 0.
b. Which method of solving a quadratic equation did you use? Explain your reasoning.
c. What type of number is Φ? Why can it only be approximated by a decimal value?
Answer:
Below.
Step-by-step explanation:
a. Φ^2 − Φ − 1 = 0
Φ2 − Φ = 1
(Φ - 0.5)^2 - 0.25 = 1
(Φ - 0.5)^2 = 1.25
Φ - 0.5 = √(1.25) (We only take the positive root).
Φ = 0.5 + √(1.25)
b. I used Completing the square.
c. Φ is irrational That is it cannot be represented as a fraction a/b and because of this it can only be approximated by a decimal.

If cot theta is greater then 0 or sin theta is smaller than 0 then terminal arm of an angle lies in quadrants
Answer:
4th quadrant
Step-by-step explanation:
Given that:
cot θ > 0 or sin θ < 0
[tex]cot \theta = \dfrac{1}{tan \theta}[/tex]
where;
[tex]tan \theta = \dfrac{sin \theta}{cos \theta}[/tex]
∴
If [tex]cot \theta = \dfrac{cos \theta}{sin \theta}>0[/tex] or sin θ < 0, then the terminal arm of the angle lies in the 4th quadrant
A car travels at a constant speed of 45 km per hour for 5 min each wheel has a radius of 25 centimeters calculate the number of complete revolutions that the wheel makes in 5 min
Answer:
477.47 revolutions
Step-by-step explanation:
From the information given:
The formula for calculating the circumference = 2π r
Given that the radius of each wheel = 25 centimeter
Then, the circumference = 2 π (25)
= 50π cm
The distance traveled in 5 minutes is as follows:
Given that:
The speed = 45 km/ hour
i.e.
1 hour = 45 km
In an hour, we have 60 minutes
So, 60 minutes = 45 km
1 minute = 45/60 = 0.75 km
To cm;
0.75 km = (0.75 × 1000) m = 750 m
750 m = 750 × 100 = 75,000 cm
∴
The number of revolution in 5 minutes sInce 1 revolution = 50π cm is:
= 75,000 cm/ 50π cm
= 477.47 revolutions in 5 minutes

Q- A bag contain red, yellow and blue beads.
The ratio of red beads to yellow beads is 2:3
The ratio of yellow beads to blue beads is 5:4
Work out what fraction of the beads are red.
Answer:
The fraction of the beads that are red is
Step-by-step explanation:
Algebraic Expressions
A bag contains red (r), yellow (y), and blue (b) beads. We are given the following ratios:
r:y = 2:3
y:b = 5:4
We are required to find r:s, where s is the total of beads in the bag, or
s = r + y + b
Thus, we need to calculate:
[tex]\displaystyle \frac{r}{r+y+b} \qquad\qquad [1][/tex]
Knowing that:
[tex]\displaystyle \frac{r}{y}=\frac{2}{3} \qquad\qquad [2][/tex]
[tex]\displaystyle \frac{y}{b}=\frac{5}{4}[/tex]
Multiplying the equations above:
[tex]\displaystyle \frac{r}{y}\frac{y}{b}=\frac{2}{3}\frac{5}{4}[/tex]
Simplifying:
[tex]\displaystyle \frac{r}{b}=\frac{5}{6} \qquad\qquad [3][/tex]
Dividing [1] by r:
[tex]\displaystyle \frac{r}{r+y+b}=\displaystyle \frac{1}{1+y/r+b/r}[/tex]
Substituting from [2] and [3]:
[tex]\displaystyle \frac{r}{r+y+b}=\displaystyle \frac{1}{1+3/2+6/5}[/tex]
Operating:
[tex]\displaystyle \frac{r}{r+y+b}=\displaystyle \frac{1}{\frac{10+3*5+6*2}{10}}[/tex]
[tex]\displaystyle \frac{r}{r+y+b}=\displaystyle \frac{10}{10+15+12}[/tex]
[tex]\displaystyle \frac{r}{r+y+b}=\displaystyle \frac{10}{37}[/tex]
The fraction of the beads that are red is [tex]\mathbf{\frac{10}{37}}[/tex]

HELP! Dont judge i really do need help!
Answer:
A.
Step-by-step explanation:
The coordinates are currently on the top left, which means one of the coordinates are negative. If you look at the chart, you can see that the X-axis is negative, and X is first on a coordinate plane. (X,Y) So, if the negative coordinate is X, and X goes first, then there's no other choice than to choose A, which is the only answer choice that has a negative X-axis in their coordinate plane! Hope this helps!

Mario spent $23.85 at the bookstore on one book and some magazines. The book cost $12.60 and the magazines cost $2.25 each. How many magazines did Mario buy?
Answer:
Mario brought 5 magazines
Step-by-step explanation:
If you just add $12.60 and $2.25 together then keep adding $2.25 until you get to $23.85, you'll get your answer.
So like,
(1) 12.60 + 2.25 = 14.85
(2) 14.85 + 2.25 = 17.1
(3) 17.1 + 2.25 = 19.35
(4) 19.35 + 2.25 = 21.6
(5) 21.6 + 2.25 = 23.85
So the total would be 5. Mario bought 5 magazines.

Helppppppp circle theorems
Answer:
m=14°, n=28°
Step-by-step explanation:
Angles in a Circle
The central angle is formed between two radii and its vertex at the center of the circle.
An inscribed angle is formed between two chords whose vertex lies on the circumference of a circle.
The measure of the central angle a formed by the same lines that form an inscribed angle b is:
a = 2b
This means the angle of a = 98° is double of the inscribed angle of 35°+m:
98 = 2(35 + m)
Dividing by 2:
49 = 35 + m
Solving for m:
m = 49 - 35 = 14
m = 14°
Angles m and n are also formed by the same lines, and:
n = 2m
Thus:
n = 28°
Answer: m=14°, n=28°
