A bird is flying at an elevation of 3 5/8 feet above sea level. A fish swims directly under the bird at a depth of 5 1/3 feet below sea level. How far apart are the two creatures?
Given :
Distance of bird from sea level, [tex]d_1 = 3\dfrac{5}{8} = \dfrac{29}{8}\ feet[/tex] .
Distance between fish and sea level, [tex]d_2=5\dfrac{1}{3}=\dfrac{16}{3}\ feet[/tex] .
To Find :
Distance between bird and fish.
Solution :
Distance between bird and fish is given by :
[tex]D=d_1+d_2\\\\D = \dfrac{29}{8}+\dfrac{16}{3}\\\\D=8.958\ feet[/tex]
Therefore, distance between bird and fish is 8.958 feet.
Hence, this is the required solution.
Simon bought 3.5 pounds of Beef on sale for $1.25 per pound at HEB. If Simon gave the cashier $10.00, how much change would he receive from this purchase?
Answer:
$5.625
Step-by-step explanation:
Cost per pound of beef = $1.25 per pound
Number of pounds purchased = 3.5 pounds
Amount given to cashier = $10.00
Amount of change to receive from cashier =?
Amount issued to cashier - total cost of beef
Total cost of beef = (number of pounds * cost per pound)
Total cost of beef = (3.5 * 1.25) = $4.375
$10 - $4.375 = $5.625

naomi has earned $54 mowing lawns the past two days. she worked 2 1/2 hours yesterday and 4 1/4 hours today. if naomi is pains the same amount for every hour she works, how much does she earn per hour to mow lawns
Answer:
Naomi charges $8 an hour to mow lawns
Step-by-step explanation:
first day // 2 1/2= 2.5 hrs
2nd day // 4 1/4= 4.25 hrs
2.5hrs + 4.25hrs = 54hrs // 6.75hrs = 54hrs
/6.75 /6.75
= 8hrs

A book sold 39,300 copies in its first month of release. Suppose this represents 6.1% of the number of copies sold to date. How many copies have been sold to dat? Round your answer to the nearest whole number
Answer:
644,262 copies
Step-by-step explanation:
Since this is a proportion problem, and we are given three values and one variable which is the total number of copies sold to date (x). Then we can use the Rule of Three to solve this problem. To do this we simply multiply the diagonal values and divide by the last value which would give us the value of the variable x
39,300 copies <======> 6.1%
x copies <=======> 100%
(100*39,300) / 6.1 = 644,262 copies
Therefore, a total of 644,262 copies have been sold to date.

The value of a rare baseball card issued in 1989 is represented by the function )-0.2-252+3x +4 where x represents the number of years since the baseball card was issued. Use the Remainder Theorem to find the value of the card in 1999
The correct format of the question is
The value of a rare baseball card issued in 1989 is represented by the function f(x) = [tex]0.2x^3- 0.25x^2+3x +4[/tex] where x represents the number of years since the baseball card was issued. Use the Remainder Theorem to find the value of the card in 1999
Answer:
The value of the card in 1999 is 209
Step-by-step explanation:
The remainder theorem says that
If you divide a Polynomial by f(x) be a Linear factor of the form (x-a) the remainder will be equal to F(a).
f(x) = [tex]0.2x^3- 0.25x^2+3x +4[/tex]
So we need to find from 1989 to 1999 which is 10 years
so our a = 10
Factor will be x-10
Applying remainder theorem
[tex]\frac{ 0.2x^3 -0.25x^2+3x+4}{x-10}[/tex]
we will get
Quotient = [tex]0.2x^2 + 1.75x +20.5[/tex]
Remainder = 209
Verifying our result
F(10) = [tex]0.2(10)^3 -0.25(10)^2 + 3(10) + 4[/tex]
= 200 -25 + 30 + 4
= 209
Find the slope of the line y= -5x -1
Answer:
-5
Step-by-step explanation:
y=mx+b is the slope intercept formula.
m is the slope.
Answer:
slope = - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 5x - 1 ← is in slope- intercept form
with slope m = - 5

Practice elimination by solving the following systems
-4-2y=-12
4+8y=-24
Answer:
y = -6
Step-by-step explanation:
-4-2y=-12
4+8y=-24
We can eliminate 4.
4+8y-4-2y = -12-24
Simplify.
6y = -36
Find y.
y = -36 ÷ 6
Simplify.
y = -6
Answer:
-4-2y=-12
4+8y=-24
by elimination method,
-4 - 2y = -12
4 + 8y = -24
---------------
0 + 6y = -36
6y = -36
y = -36/6
y = -6
hope it helps you!!

What is the approximate area of the circle shown below? (The radius is 21cm)
A. 1385 cm2
B. 66 cm2
C. 5540 cm2
D. 132 cm
Answer:
The answer is A. 1385 cm2
Step-by-step explanation:
Use the formula A = pi times radius squared
Answer:
A. 1385 cm²
Step-by-step explanation:
Area of a circle is πr²
We know what the radius is, so all we have to do is plug it in.
π(21)²
π(21)²= 1385.44
Since it's approximate, it would just be 1385 cm²

Answer:
this should be correct, im sorry im wrong.
Step-by-step explanation:
Answer:
Look at explanation
Step-by-step explanation:
y = mx + b
m is the slope, and b is the y-intercept
So basically on the y-axis, which is the vertical line, u will make a point on 4, and that point is where your line will go through. And then 3 is the slope ur line will be going in, meaning that the line will go up 3 square units, or number, while only going one square unit to the right. It's going up and right because it's a positive number. So it should look like this:

28 in 21 in., 20 in.
Is this a right triangle?
Answer:
No, it is not a right triangle.
Step-by-step explanation:
The simplest way to determine is testing out the numbers with Pythagorian theorem.
If it complies with the theorem, it is a right triangle.
let's assume c = 28, b = 21, and a = 20
the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.
According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.
check:
c^2 = 28^2 = 784
a^2 + b^2 = 21^2 + 20^2 = 841
because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.

A running back on the high school football team was tackled for a 10-yard loss. On the very next play, the running back gains 10 yards. How many yards does the running back have after these two plays? Please hellpppp
Answer:
He has 0 yards
Step-by-step explanation:
Initially he lost 10 yards
This means that he is 10 yards away from the starting point which we shall call origin
Afterwards, he gained 10 yards
what this mean is that he is back at the original point before the loss
Since he gained what he lost, then he is back at the origin and then we can say that no yards was lost or gain so we have him gaining 0 yards only
