A rectangle has an area of 1,280.64 square miles and a base of 36.8 miles. What is the height?
Answer:
34.8 miles
Step-by-step explanation:
First, we know that Area = Length * Width. Let's plug in those values.
1,280.64 = x * 36.8 (I put the variable "x" there since we don't know what it is)
Now, solve for x (we want to have x by itself, so divide both sides by 36.8)
34.8 = x
Now that we know that the width of it is 34.8 miles, let's check our work.
34.8 * 36.8 = 1,260.64
This equation IS true, so:
The width of the rectangle is 34.8 miles. Hope this helps!

Answer:
Other root of equation, [tex]\frac{8}{3}[/tex]
Value of ([tex]b[/tex]), [tex]-17[/tex]
Step-by-step explanation:
The given quadratic equation is in standard form. Standard form is the basic format of representing a quadratic equation, a quadratic equation in standard form would use the following format,
[tex]y=ax^2+bx+c[/tex]
To solve this problem, one could use Vieta's theorems. Vieta's theorems state the following, let ([tex]x_1[/tex]) and ([tex]x_2[/tex]) represent the roots of the equation,
[tex](x_1)+(x_2)=-\frac{b}{a}[/tex]
[tex](x_1)(x_2)=\frac{c}{a}[/tex]
Substitute the given values into the equation,
[tex]3+(x_2)=-\frac{b}{3}[/tex]
[tex](3)(x_2)=\frac{24}{3}[/tex]
Simplify,
[tex](3)+(x_2)=-\frac{b}{3}[/tex]
[tex](3)(x_2)=8[/tex]
Inverse operations,
[tex](3)+(x_2)=-\frac{b}{3}[/tex]
[tex]x_2=\frac{8}{3}[/tex]
Substitute in the value of ([tex]x_2[/tex]),
[tex](3)+(\frac{8}{3})=-\frac{b}{3}[/tex]
Simplify, convert to improper fractions and combine like terms,
[tex]\frac{9}{3}+\frac{8}{3}=-\frac{b}{3}[/tex]
[tex]\frac{17}{3}=-\frac{b}{3}[/tex]
Multiply both sides of the equation by ([tex]3[/tex]) to remove the denominator,
[tex]17=-b[/tex]

Answer:
about 236.715 ft²
Step-by-step explanation:
area of a circle = πr²
so π7.5² = 176.7145868
area of a rectangle is b × h
so 15 × 4 = 60
60 + 176.7145868 = 236.7145868 ft² ≈ 236.715 ft² (for the nearest thousandths)
What’s the answer?!!!!!
Answer:
yes
because it has length, side and base
Answer:
No
Step-by-step explanation:
If it is a right angled triangle, then it will satisfy the pythagoras theorem, which is as follows:
Perpendicular² + Base² = Hypotenuse²
{hypotenuse is the longest side in a right-angled triangle}
LHS : Perpendicular² + Base²
(15)² + (10)² = 225 + 100 = 325
RHS : Hypotenuse²
(17)² = 289
LHS ≠ RHS
Does not satisfy pythagoras theorem
So the triangle is not right angled

The Nisbets went through the drive through
at the donut shop and spent $10.50 on 2
cups of coffee and 4 donuts. Behind them,
the Roys spent $8.25 on 1 cup of coffee and
5 donuts. What is the cost of one cup of
coffee?
Answer:
One cup of coffee is $3.25
Step-by-step explanation:
Create a system of equations where c is the cost of a cup of coffee and d is the cost of a donut
2c + 4d = 10.5
c + 5d = 8.25
Solve by elimination by multiplying the top equation by -5 and the bottom equation by 4
-10c - 20d = -52.5
4c + 20d = 33
Add them together and solve for c
-6c = -19.5
c = 3.25
So, a cup of coffee is $3.25

if U=π (r+h),find the value of "r" when U=16 whole 1 upon 2 and h=2
Answer:
r = 3 1/4
Step-by-step explanation:
Here, we want to find the value of r given the values
Firstly, we will write r as the subject of the formula
U = π ( r + h)
U/π = r + h
r = U/π - h
Now substitute;
U = 16 1/2 = 33/2
h = 2
π= 22/7
r = 33/2/22/7 - 2
r = (33/2 * 7/22) - 2
r = 21/4 - 2
r = (21-8)/4
r = 13/4 = 3 1/4

card. How many pounds of coffee did she buy?
Il pounds
Answer:

Find the ratio of the volume of the triangular prism
to the volume of the cuboid,
Give your answer in its simplest form
고
Answer:
The ratio of the volume of the triangular prism to the volume of the cuboid is [tex]\frac{3}{20}[/tex].
Step-by-step explanation:
Geometrically speaking, the volume of the prism is equal to the product of the area of the base and its height. Then, the volumes of the triangular prism and the cuboid are, respectively:
Triangular prism
[tex]V_{tp} = \frac{1}{2}\times 5\,cm \times 4\,cm \times 9\,cm[/tex]
[tex]V_{tp} = 90\,cm^{3}[/tex]
Cuboid
[tex]V_{c} = 6\,cm\times 5\,cm \times 20\,cm[/tex]
[tex]V_{c} = 600\,cm^{3}[/tex]
Lastly, the ratio of the volume of the triangular prism to the volume of the cuboid is:
[tex]r = \frac{V_{tp}}{V_{c}}[/tex]
[tex]r = \frac{3}{20}[/tex]
The ratio of the volume of the triangular prism to the volume of the cuboid is [tex]\frac{3}{20}[/tex].
Seven friends change counts in their pockets.They have $0.00,$1.25,$0.02,$2.00,$10.75,$0.40 and $0.00.What is the median amount of pocket change per person?
Answer: .4
Step-by-step explanation:
The median means the middle of a list of numbers so rearrange the numbers from smaller to greatest:
0, 0, .02, .4, 1.25, 2, 10.75
Thus the middle of this list is .4.
Hope this helps
Answer:
0.40
Step-by-step explanation:
Here is a list of the data in order from least to greatest:
$0.00, $0.00, $0.02, $0.40, $1.25, $2.00, $10.75.
There are seven numbers in the list, so the median is the fourth number, which is $0.40.
Mr. Palmer deposited $850 into a simple interest account for 8 years, earning at an 8% interest rate. What will his total balance be when he checks it?
I DO NOT WANT A LINK!!!!!!!!
Answer:
solution given:
principal [P]=$850
time[T]=8years
rate[R]=8%
now
simple interest [S.I.]=[tex] \frac{P×T×R}{100}[/tex] =$ [tex] \frac{850×8×8}{100}[/tex] =$544
so
Total balance=S.I.+P=$544+$850=$1394.

Which translation vector moves every point of a pre-image 4 units left and 6 units up?
F. (4, -6)
G. (-4, 6)
H. (-6, 4)
J. (6, -4)
Answer:
G(-4,6)
Step-by-step explanation:
Here, we want to write a translation
moving left means we are to subtract the number of units from the original
So we have this as -4
Moving up means we are to add the number of units to the original
So we have this as +6 = + 6 units
So the answer here will be;
(-4,6)
G. (-4, 6).
Given translation is 4 units left and 6 units up.
For left we use negative sign. And for up was use plus sign.
So the translation vector is (-4, 6).

I don’t know what to do
Answer:
x = 14.4
Step-by-step explanation:
Similar means that the figures are proportional to each other. Because of this, we can form a problem. [tex]\frac{9}{5}[/tex] (the short side lengths) = [tex]\frac{x}{8}[/tex] (the long side lengths). Now we can solve this by cross-multiplying. If we multiply 9 · 8 we get 72, and 5 · x is 5x. 72 = 5x. Now divide both sides by 5. 72 ÷ 5 = 14.4. Therefore, x should be equal to 14.4. Does this make sense?

Determine the area of the parallelogram.use proper units
Answer:
180 in^2
Step-by-step explanation:
to find the height you need to look at the triangle and apply pythagorean theorem
5^2=x^2=13^2
25+x^2=169
x^2=144
x=12
now we can find the area of the parallelogram:
b*h=area
15*12=180 in^2
The area of the parallelogram is 180 in^2
