Answer:
y = 24/xStep-by-step explanation:
An inverse variation equation is:
y = k/xWe have y = 3 when x = 8, find the coefficient k:
3 = k/8k = 3*8k = 24The equation is:
y = 24/xFind the value of x.
x 13 39
Answer:
13x-39=39
13x=78
the answer is x=6

Step-by-step explanation:
A beehive contains 5 gallons of honey. A beekeeper removes 4 gallons, 1 pint, and 2 ounces. How much honey remains in the beehive?
how many quarts_____ and how many ounces_____
Answer:
3 quarts and 14 ounces of honey remain in the beehive.
Step-by-step explanation:
Pint = 16 ounces
Gallon = 128 ounces
Quart = 32 ounces
So, we start with a total of 640 ounces of honey. The beekeeper removes 530 ounces, leaving 110 behind. 32 ounces in a quart means that there are 3 full quarts in the hive as well as 14 ounces.
What is a formula for the nth term of the given sequence? 15,75,375
Answer:
3 × 5 ^ n
Step-by-step explanation:
since the series is exponential, the ratio between adjacent terms is 5.
nth term of geometric/exponential series is given by:
nth term = first term × (ratio)^(n-1)
= 15 × 5^ (n-1)
= 15 × 5^n × 5^-1
= 3× 5^n
Substitution method.
y=x - 5
y —3х – у = -3
Answer : ( 1, - 4 )
Explanation : y=x - 5
y —3х – у = -3
Step 1 : Consider the first eqaution. Subtract X from both sides.
y - x = -5
Step 2 : Consider the second eqaution. Combine y and -y to get 0 .
-3x = -3
Step 3 : Divide both sides by -3
x = -3 / -3
Step 4 : Divide -3 by -3 to get 1
x = 1
Step 5 : Consider the first eqaution. Insert the known values of variables into the equation.
y - 1 = -5
Step 6 : Add one to both sides.
y = -5 + 1
Step 7 : Add negative 5 and one to get negative 4 .
y = -4
Therefore, the answer is ( 1, - 4 )

At the Middleton School festival, a tent covers a rectangular space 30 1/2 yards long and 9 1/3 yards wide. What is the area, in square yards, covered by the tent?
Please help? I’m really confused
Answer:
48.2 in^3
Step-by-step explanation:
It'd be easier to calculate the volume if you'd change the mixed numbers to mixed numers with decimal fractions:
2 1/2 becomes 2.5
3 2/3 becomes 3.67
5 1/4 becomes 5.25
Then V = L*W*H, or
V = (5.25 in)(3.67 in)(2.5 in) = 48.2 in^3

The trait for a dimples (D) is dominant over the trait for no dimples (d). Two people with dimples (Dd x Dd)
got married. Complete the diagram below to show the genes of their children. What percentage of the
offspring will most likely have no dimples?
0%
25%
50%
75%
Answer:
25%
Step-by-step explanation:
Here is my punnett square:
D d <---parent 1
D DD Dd
d Dd dd
^
|
| parent 2
The results: DD, Dd, Dd, dd
DD, Dd: will have dimples because they have a dominant allele in their genotype. So in their phenotype, they will have dimples.
dd: will not have dimples because they do not have the dominant allele for dimples in their genotype. So in their phenotype, they will NOT have dimples.
3 cases (25% chance for DD, 50% chance for Dd, 25% chance for dd)
1/4 is DD is 25%
2/4 is Dd is 50%
and 1/4 is dd is 25%
answer: 25%

for each meal, Jeffrey eats either toast, cereal, or pancakes. How many different ways can Jeffrey choose his three meals for the day? PLSS HELP ASAP RN!
Answer:
27
Step-by-step explanation:
Jeffrey has three choices for breakfast: toast, cereal, or pancakes. Then, he has three choices for lunch: toast, cereal, or pancakes. Finally, he has three choices for dinner: toast, cereal, or pancakes.
Putting these together, Jeffrey has 3 * 3 * 3 = 27 possible ways to select the three meals.
Priya has planted a garden shaped like a right triangle. One leg of the triangle is 5 meters long, and the triangle formed by it and the hypotenuse is 50 grades. If Priya wants to build a fence around her garden, how many meters of fence will she need?
Answer:
Perpendicular = 6 meter (Approx.)
Length of fence required = 18.81 meter
Step-by-step explanation:
Given:
One side of triangle = 5 m
Angle with side and hypotenuse = 50°
Find:
Other sides
Length of fence required
Computation:
Using trigonometry function;
Tanθ = Perpendicular / Base
For 50° angle , 5 m is base
Tan 50 = Perpendicular / 5
1.1917 = Perpendicular / 5
Perpendicular = 5.9585
Perpendicular = 6 meter (Approx.)
Hypotenuse = √Perpendicular² + Base²
Hypotenuse = √6² + 5²
Hypotenuse = √36 + 25
Hypotenuse = √61
Hypotenuse = 7.81 meter (Approx.)
Length of fence required = 5 + 6 + 7.81
Length of fence required = 18.81 meter

Find the equation of the line that passes through (1,2) and is perpendicular to y=2x+3. Leave your answer in the form y=mx+c
Answer:
y = -1/2x + 5/2
Step-by-step explanation:
If two lines are perpendicular to each other, they have opposite slopes.
The first line is y = 2x + 3. Its slope is 2. A line perpendicular to this one will have a slope of -1/2.
Plug this value (-1/2) into your standard point-slope equation of y = mx + b.
y = -1/2x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (1, 2). Plug in the x and y values into the x and y of the standard equation.
2 = -1/2(1) + b
To find b, multiply the slope and the input of x (1)
2 = -1/2 + b
Now, add 1/2 to both sides to isolate b.
5/2 = b
Plug this into your standard equation.
y = -1/2x + 5/2
This equation is perpendicular to your given equation (y = 2x + 3) and contains point (1, 2)
