Answer:
Area = 20 sq yd
Step-by-step explanation:
Use area of a triangle to solve:
A = 1/2 b•h
A = 1/2(10)(4)
A = 20 sq yd
Any side can be a base. The height must be perpendicular to that base. Turn this triangle to see base and height are given. See image.

inverse property
Answer:
(b) commutative property
Step-by-step explanation:
The "simplified" expression has the positions of the last two terms in the sum swapped. The property of addition that lets you change the order of the terms is the commutative property of addition.

Answer:
[tex]\textsf{D.}\quad\dfrac{b}{\sqrt{a^2+b^2}}[/tex]
Step-by-step explanation:
Tan trig ratio
[tex]\tan(x)=\sf \dfrac{O}{A}[/tex]
where:
[tex]x[/tex] is the angleO is the side opposite the angleA is the side adjacent the angleUsing the given information:
[tex]\implies x=\tan^{-1}\left(\dfrac{a}{b}\right)[/tex]
[tex]\implies \tan(x)=\tan\left(\tan^{-1}\left(\dfrac{a}{b}\right)\right)[/tex]
[tex]\implies \tan(x)=\left(\dfrac{a}{b}\right)[/tex]
Comparing this with the trig ratio, we can say that:
[tex]x[/tex] is the angle opposite side [tex]a[/tex]
Cos trig ratio
[tex]\cos(x)=\sf \dfrac{A}{H}[/tex]
where:
[tex]x[/tex] is the angleA is the side adjacent the angleH is the hypotenuseTherefore:
A = side [tex]b[/tex]H = side [tex]\sqrt{a^2+b^2}[/tex][tex]\implies \cos\left(\tan^{-1}\left(\dfrac{a}{b}\right)\right)=\cos(x)= \dfrac{b}{\sqrt{a^2+b^2}}[/tex]
Derek lives in canada and enjoys herb gardening. his american friend sent him a guidebook for growing fresh herbs. the book says that it is best to cut bay shoots when they are 3.25 in long. if 1 mm is equivalent to 0.03937 in, how many millimeters long should the bay shoots be when derek cuts them? a. 8.26 mm b. 12.80 mm c. 82.55 mm d. 95.67 mm
When the bay shoots are 82.55 mm, Derek should cut them according to the guidebook for growing fresh herbs option (c) is correct.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, multiplication by a conversion factor.
The book says that it is best to cut bay shoots when they are 3.25 in long.
As it is given that the:
1 mm = 0.03937 in
To find how many millimeters long should the bay shoots be when Derek cuts them, we must convert 3.25 in to mm
From the 1 mm = 0.03937 in, we can find how many mm is there in 1 in;
[tex]\rm 1 \ in= \frac{1}{0.03937} \ mm[/tex]
To convert 3.25 in into mm, we must multiply it by 1/0.03937
= 3.25×(1/0.03937)
= 82.55 mm
Thus, when the bay shoots are 82.55 mm, Derek should cut them according to the guidebook for growing fresh herbs option (c) is correct.

Harry's kitchen table is round and has a radius of 2 feet. What is the tabletop's diameter?
Answer:
4
Step-by-step explanation:
An object's radius is half of the object's diameter.
Solving for diameter
d = r * 2Solving for radius
r = d/2d = r * 2
= 2 * 2
= 4

Answer:
[tex]\boxed{\sf x < -3\quad \mathrm{or}\quad \:x > -1}[/tex]
Step-by-step explanation:
[tex]\sf x^2+4x+3 > \:0[/tex]
In order to solve inequality, we need to factor the left hand side. we can use the transformation [tex]ax^2+bx+c=a(x-x_1)(x-x_2)[/tex] to factor quadratic polynomials. where x(1) & x(2) are the solutions of the quadratic equation ax²+bx+c=0 .
[tex]\sf x^2+4x+3=0[/tex]
Quadratic formula:-
[tex]\boxed{\sf x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}}[/tex]
[tex]\sf a=1\\b=4\\c=3[/tex]
[tex]\sf \cfrac{-4\pm \sqrt{4^2-4\times \:1\times \:3}}{2\times \:1}[/tex] ← Calculate
[tex]\sf \sqrt{4^2-4\times \:1\times \:3}=\boxed{2}[/tex]
[tex]\sf \cfrac{-4\pm \:2}{2\times \:1}[/tex]
Now, let's Separate the solutions,
[tex]\sf x_1=\cfrac{-4+2}{2\times \:1},\:x_2=\cfrac{-4-2}{2\times \:1}[/tex]
Do the calculations,
[tex]\sf x_1=\cfrac{-4+2}{2\times \:1}=\boxed{-1}[/tex]
[tex]\sf x_2=\cfrac{-4-2}{2\times \:1}=\boxed{-3}[/tex]

It takes 12 hours to make a trip going 50 mph. How fast would you need to go to make it in 10 hours?
Answer:
10 hours = 60 mph
you will need to go 60 mph to make the trip 10 hours
explaination:
Multiplying the amount of hours and the mph, 12 times 50 is 600 miles.
10 times 60 is 600 miles. They both have the same answer, but 60 mph is the fastest. 60 mph is how fast you would need to go to make it in 10 hours.

What is the value of x?
Answer:
Step-by-step explanation:
Sum of all angles of triangle = 180
17x + 10x -5 + 50 = 180
Combine like terms
27x + 45 = 180
To find the valu of x, we have to isolate x. To isloate x
Step 1: Subtract 45 from both sides
27x = 180 - 45
27x = 135
Step 2: Divide both sides by 27
x = 135/27

Which statement is true?
We will see that the fourth statement:
"-0.3*|3 + 8x| = 0.9 has no solutions."
Is the true statement.
Which statement is true?Here we need to see which statement regarding absolute value equations is true.
Here you can see that the fourth statement is:
-0.3*|3 + 8x| = 0.9 has no solutions.
Now, if you look at the left side of the above equation, the left side will always be negative, while the right side is positive, then the equation can't have a solution.
There is no value of x that makes that equation true, so it is true that the given equation has no solutions. This is the correct statement.

Answer:
x = 7.5, x = -5
Step-by-step explanation:
1. Plug a(2), b(-5), and c(-75) into the qudratic formula:
[tex]x_{1,2} =\frac{-(-5)+-\sqrt{(-5)^{2}-4(2)(-75) } }{2(2)}[/tex]
2. Find the square:
[tex]x_{1,2} =\frac{-(-5)+-\sqrt{25-4(2)(-75) } }{2(2)}[/tex]
[tex]x_{1,2} =\frac{-(-5)+-\sqrt{25+600} }{2(2)}[/tex]
[tex]x_{1,2} =\frac{-(-5)+-25 }{4}[/tex]
3. Separate the solutions:
[tex]x_{1} = \frac{-(-5)+25}{4} , x_{2} =\frac{-(-5)-25}{4}[/tex]
4. Solve for both:
[tex]x_{1} =\frac{5+25}{4} \\\\x_{1} =\frac{30}{4} \\\\x_{1} =\frac{15}{2}\\\\x_{1} =7.5[/tex]
--------------------
[tex]x_{2} =\frac{5-25}{4} \\\\x_{2} =\frac{-20}{4} \\\\x_{2} =-5[/tex]
In conclusion, the solutions are x = 7.5 and -5.

What is the inverse of `y = 5x + 7
Show Steps!
Answer:
[tex]\sf y' = \dfrac{x-7}{5}[/tex]
Explanation:
⇒ y = 5x + 7
⇒ 5x + 7 = y
⇒ 5x = y - 7
⇒ x = (y-7)/5
replace x with y
⇒ y' = (x-7)/5
Take this and solve for x
5x=y-7x=y-7/5Interchange y and x
y=x-7/5So
The inverse is

What type of triangle is defined by the following set of side lengths
11, 9 , 7
Acute
Obtuse
Right
Not a triangle
Answer:
ACUTE TRIANGLE
Step-by-step explanation:
If the sum of the squares of the two shorter sides of a triangle is greater than the square of the longest side, the triangle is acute. However, if the sum of the squares of the two shorter sides of a triangle is smaller than the square of the longest side, the triangle is obtuse.
Therefore, the triangle with sides 11, 9, and 7 is an acute triangle since 9² + 7² is greater than 11²
