An animal shelter has 34 dogs and 62 cats. Find the ratio of dogs to cats
Answer:
17 : 31
Step-by-step explanation:
[tex]\frac{34}{62} =\frac{17}{31}[/tex]
Answer:
17:31
Step-by-step explanation:
We can simplify the ratio 34 : 62 by dividing both terms by the greatest common factor (GCF).
The GCF of 34 and 62 is 2.
Divide both terms by 2.
34 ÷ 2 = 17
62 ÷ 2 = 31
Therefore:
34 : 62 = 17 : 31

Imagine that you traveled back in time to the Fourth of July, 1999. You are at Stanford Stadium, watching the semifinal of the Women's World Cup soccer match. Mia Hamm, star of the United States team, has just received the ball on a breakaway. She is 60 yards from Brazil's goal. Brazilian star Sissi is the closest opponent to Hamm and is 10 yards behind her. Mia takes off for Brazil's goal and, while dribbling the ball, is able to run at a speed of 6.8 yards per second. Sissi takes off at the same time as Hamm and runs at 8.4 yards per second. (She is able to run faster because she isn't dribbling the soccer ball.) Hamm has decided to shoot at the exact moment that Sissi catches up to her, because at that point it will still be difficult for Sissi to block the shot when she is side by side with Hamm. How far away from the goal will Hamm be when she shoots
Answer:
17.5 yards
Step-by-step explanation:
Speed is the ratio of distance to time. It is given by the formula:
Speed = distance / time
Mia Hamm is running at a speed of 6.8 yards per second. Let us assume that Mia covers a distance (d) during time (t) when Sissi catches up to her. Hence:
6.8 = d / t
t = d / 6.8
Sissi was 10 yards behind Mia Hamm and running at 8.4 yards per second. Therefore:
8.4 = (d + 10) / t
t = (d + 10)/ 8.4
d / 6.8 = (d + 10)/ 8.4
8.4d = 6.8d + 68
1.6d = 68
d = 42.5 yards
Mia had covered 42.5 yards when Sissi catches up with her. Therefore Mia Hamm distance to goal = 60 yards - 42.5 yards = 17.5 yards

Employees at the ACME paper bag corporation have two fast food restaurant chains located next to the corporate parking lot: Carl's Jr. and Wendy's. Due to time restrictions the ACME employees eat their lunches either at Carl's Jr. or Wendy's and nowhere else. If today an employee eats lunch at Wendy's, then tomorrow the probability they'll eat lunch at Wendy's is 10% otherwise they'll eat lunch at Carl's Jr. If today an employee eats lunch at Carl's Jr., then tomorrow the probability they'll eat lunch at Carl's Jr. is 40% otherwise they'll eat lunch at Wendy's. If on Monday an employee eats lunch at Carl's Jr. what is the probability they'll eat lunch at Carl's Jr. Wednesday?
Answer:
0.7 = 70% probability they'll eat lunch at Carl's Jr. Wednesday.
Step-by-step explanation:
We have that:
Carl's Jr on Monday.
On Tuesday:
40% probability of Carl's Junior.
100 - 40 = 60% probability of Wendy's.
On Wednesday:
If on Tuesday it was on Carl's Junior, 40% probability of Carl's Junior on Wednesday.
In on Tuesday it was on Wendy's, 100 - 10 = 90% probability of Carl's Junior on Wednesday.
What is the probability they'll eat lunch at Carl's Jr. Wednesday?
[tex]p = 0.4*0.4 + 0.6*0.9 = 0.7[/tex]
0.7 = 70% probability they'll eat lunch at Carl's Jr. Wednesday.

An arch in the shape of the upper half of an ellipse is used to support a bridge that is to span a river 60 meters wide. The middle of the arch is 10 meters above the center of the river. Start by writing an equation for the ellipse if the x-axis coincides with the water level and the y-axis passes through the center of the arch. How high above the river is the arch at a distance of 8 meters from the center?
The arch is ____ meters above the river at a distance of 8 meters from the center. Do not round until the end. Round to the nearest tenth of a meter.
Answer:
Step-by-step explanation:
(y/10)^2+(x/30)^2=1
y^2/100+x^2/900=1
9y^2+x^2=900
9y^2=900-x^2
y^2=(900-x^2)/9, when x=8 we have
y^2=(900-8^2)/9
y^2=(900-64)/9
y^2=836/9
y=9.6 meters
The arch is 9.6 meters above the river at a distance of 8 meters from the center.

Answer:

Step-by-step explanation:
subtract the post-discount price from the pre-discount price
64.99 - 45.49 = 19.50
divide the answer by the original price
[tex]\frac{19.50}{64.99}[/tex] = 0.30
multiply the answer by 100
0.30 x 100 = 30%
to check:
take the original number and multiply it by the decimal form of the percentgae:
64.99 x 30% (0.30) = 19.50
take the answer and subtract it from the orginal answer
64.99 - 19.50 = 45.49

Ken flips 2 fair coins.
What is the probability of obtaining the same result on each coin?
Answer:
Hello there! There is a 1/4 chance of getting the same result on both flips, keeping in mind that a coin only has 2 sides.
Step-by-step explanation:
There is a 1/2 chance of getting a result on one flip. So we now have to multiply that by getting the same result on another flip.
1/2 × 1/2 = 1/4
Hope this helps! :)
The probability of obtaining the same result on each coin will be 1/2.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
Ken flips 2 fair coins. The total events are given as,
Total event = 2 x 2
Total event = 4 {TT, HT, TH, HH}
The probability of obtaining the same result on each coin will be given as,
Favorable events = 2 {TT, HH}
P = 2 / 4
P = 1/2
The probability of obtaining the same result on each coin will be 1/2.

Jason made the following calculations. Explain the errors Jason made. Give the correct answers.
a. 1/3 + 3/5 = 4/8
b. 11/12 - 5/6 = 6/6 = 1
Answer:
a. 14/15
b. 1/12
Step-by-step explanation:
a) 1/3 + 3/5
so find the lowest common multiple for the denominators which is 15
then say 15 ÷ 3 = 5
then 15 ÷ 4 = 3 (you are dividing by the denominators)
say 5 × 1 (multiple by the numerators now)
= 5
= 5/15
now say 3 × 3 = 9
= 9/ 15
now it's 5/15 + 9/15
= 14/15
Jason made an error that he just added the denominators without applying any formula.
b. 11/12 - 5/6
find the lcm
= 12
11/ 12 × 1/1 = 11/12
5/6 × 2/2 = 10/12
11-10
= 1
= 1/12
Jason made a mistake that he said 12-6 instead of finding the LCD them multiplying that fractions
The errors Jason made that he did not take LCM of denominators.
What are denominators?In math, a denominator can be defined as the bottom number in a fraction that shows the number of equal parts an item is divided into.
Given are some calculations done by Jason,
We know that, to add two fractions, we take LCM of denominators and then divide the numerator by LCM and the add,
a) 1/3 + 3/5 = 4/8
Here, Jason have not taken LCM of denominators
Correction =
[tex]\frac{15(\frac{1}{3} )+15(\frac{3}{5}) }{15} \\= \frac{5+9}{15} \\=\frac{14}{15}[/tex]
b) 11/12 - 5/6 = 6/6 = 1
Again, the error is the same.
LCM(6, 12) = 12
Correction =
[tex]\frac{12(\frac{11}{12})+12(\frac{5}{6)} }{12} \\= \frac{11-10}{12} \\= \frac{1}{12}[/tex]

A line contains the points (6,-4) and (0,-2). What is the equation of the line?
Answer:
The equation of the line is:
[tex]y = -\frac{1}{3}x - 2[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept, that is, the value of y when x = 0.
(0,-2)
This means that the y-intercept is -2, that is, [tex]b = -2[/tex]. So
[tex]y = mx - 2[/tex]
Finding the slope:
When we have two points, the slope is given by the change in y divided by the change in x.
We have points (6,-4) and (0,-2).
Change in y: -2 - (-4) = -2 + 4 = 2
Change in x: 0 - 6 = -6
Slope: [tex]m = \frac{2}{-6} = -\frac{1}{3}[/tex]
So the equation of the line is:
[tex]y = -\frac{1}{3}x - 2[/tex]
