Answer:
The ratio of the number of cows to the number of sheeps in the farm is;
[tex]\begin{gathered} \frac{4}{5} \\ Or \\ 4\colon5 \end{gathered}[/tex]Explanation:
Given that;
there were 75 sheep
and 60 cows
We want to find the ratio of the number of cows to the number of sheeps in the farm;
[tex]\text{ratio}=\frac{\text{ number of cows }}{\text{ number of sh}eeps}=\frac{60}{75}[/tex]reducing the ratio to the least form;
[tex]\text{ratio=}\frac{60}{75}=\frac{4}{5}[/tex]Therefore, the ratio of the number of cows to the number of sheeps in the farm is;

Answer:
378,075
Explanation:
The population of Ashton in 2007 = 294876
The population increases at a constant rate of 2.8%.
Therefore, the population at any time, t after 2007 is:
[tex]\begin{gathered} P(t)=294876(1+2.8\%)^t \\ P(t)=294876(1+0.028)^t \\ P(t)=294876(1.028)^t \end{gathered}[/tex]Therefore, the population in 9 years time will be:
[tex]\begin{gathered} P(9)=294876(1.028)^9 \\ =378074.6 \\ \approx378,075 \end{gathered}[/tex]The predicted population in 9 years will be 378,075.
Anna found that there are 3^4 options for pizzas with different loppings at her local are there for pizzas? B. 12 c. 64 D.BA ker notes
As there are 3^4 options for pizzas, we can calculate this as:
[tex]3^4=3\cdot3\cdot3\cdot3=81[/tex]Answer: 3^4 options is equivalent to 81 options (option D).
8i+ 5 - 2i equals 3i+ 23
We will have:
[tex]8i+5-2i=3i+23[/tex]We will operate like terms and solve for i, that is:
[tex]8i-2i-3i=23-5\Rightarrow3i=18\Rightarrow i=6[/tex]*Step by step:
[tex]8i+5-2i=3i+23\Rightarrow6i+5=3i+23[/tex][tex]\Rightarrow6i+5-5=3i+23-5\Rightarrow6i=3i+18[/tex][tex]\Rightarrow6i-3i=3i+18-3i\Rightarrow3i=18[/tex][tex]\Rightarrow\frac{3}{3}i=\frac{18}{3}\Rightarrow i=6[/tex]There are 364 people That have to go from the airport to the hotel. One sand can’t transfer 12 people have any vans are needed
To find the number of van that are needed you divide the number of people into the people that a van can transport:
As the result of division is a decimal number you approximate it to the next whole number (because you can not have 0.33 of a van)
Then, there are needed 31 vansChase rode a Ferris wheel 93 timesaround, one lap after the other. If eachlap of the Ferris wheel took 20 seconds,how long was Chase's ride?minute
If Chase rode 93 times around, and each lap takes 20 seconds, to find out how long was Chase's ride we must multiply the time for each lap, and how many laps she did, then, the calculus will be
[tex]time=93\cdot20[/tex]The result will be in seconds!
[tex]\begin{gathered} time=93\cdot20 \\ \\ \text{time}=1860\text{ seconds} \end{gathered}[/tex]Then Chase's ride was 1860 seconds long! We can covert it in minutes by doing the division by 60
The time in minutes will be
[tex]\begin{gathered} \text{time}=\frac{1860}{60}\text{ minutes} \\ \\ \text{time}=31\text{ minutes} \\ \end{gathered}[/tex]Therefore, Chase's ride took 31 minutes

The intersection of plane STUV and plane UYXT will be the line segment TU.
The task is to determine the intersection of the planes UYXT and STUV.
We are aware of;
When two planes overlap, their intersection is a straight line.
The points 'T' and 'U' are shown in the picture to be on both planes UYXT and STUV.
As a result, the line connecting these two points, that is, the line TU likewise lies on both planes.
As a result, the line 'TU' is formed by the intersection of both planes.
Thus, the intersection of plane STUV and plane UYXT will be the line segment TU.

Step-by-step explanation:
We can use the slope formula to find the slope of a line given the coordinates of two points on the line:- (3,64) and (9,79).
The coordinates of the first point represent x_1 and y_1. The coordinates of the second points are x_2, y_2.

Answer:
m = (y2 - y1)/(x2 - x1) m = 15/6 m = 2.5Step-by-step explanation:
Formula we use,
→ m = (y2 - y1)/(x2 - x1)
Then the required slope is,
→ m = (y2 - y1)/(x2 - x1)
→ m = (79 - 64)/(9 - 3)
→ m = 15/6
→ [ m = 2.5 ]
Hence, the slope is 2.5.
Using the image above, which of the following are opposite rays?A QP and PLB PL and PQC LP and QPD LQ and PQ
ANSWER
PL and PQ
EXPLANATION
We want to find which of the rays are opposite rays.
That means which of the rays are going in opposite direction and are the same length to one another.
We see different rays in the image. Some are going upward while some are going downward.
The ones going upward are:
LQ and PQ
The ones going downward are:
QL and PL
By observation, among all the options, we see that only PL and PQ are the same length and that are in opposite directions.
That means that the answer is PL and PQ

Given that the figure has vertices (-13,13), (26,52), (39,39), to reduce the image by a scale factor of 0.77 with the origin as the center of dilation, we will multiply the x and y coordinates by the scale factors.

[tex]\text{focus}=(h+p,k)[/tex]and the directrix is

Answer:
Invest today: $8895.36
Interest earned: $3104.64
Explanation:
The amount after t years can be calculated as:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]Where P is the initial amount invested, r is the interest rate and t is the number of years and n is the number of times the interest rate is compound. Solving the equation for P, we get:
[tex]P=\frac{A}{(1+\frac{r}{n})^{nt}}[/tex]Now, we can replace A by $12,000, r by 5% = 0.05, n by 12 because it is compounded monthly and t by 6
[tex]P=\frac{12000}{(1+\frac{0.05}{12})^{12(6)}}=8895.36[/tex]Therefore, he should invest $8895.36 today to have enough money in 6 years.
Finally, the interest earned is calculated as
$12000 - $8895.36 = $3104.64
So, the answers are:
Invest today: $8895.36
Interest earned: $3104.64

is the least common denominator of two fractions always greater than the denominators of the fractions
The least common denominator of two fractions is not always greater than the denominators of each fraction because sometimes the least common denominator is equal to the greater denominator. For example, if we have the fractions
[tex]\frac{4}{5}-\frac{1}{5}[/tex]In this case, since you have equal denominators, the least common factor would be 5, not greater than 5.
Another example could be
[tex]4+\frac{2}{9}[/tex]In this case, the least common denominator is 9, not greater than 9.
Therefore, the least common denominator is not always greater than the denominator of the fractions.A hummingbird can travel up to 15 meters per second.What is the hummingbird's speed in miles per hour?1 mile ≈ 1609 meters Enter your answer, as a decimal to the nearest tenth, in the box. mph
