Answer:
Answer:
[tex]x = 13.8[/tex]
Step-by-step explanation:
Given
See attachment for triangle
Required
Find x
To find y, we make use of the relationship between sides lengths 11 & x and angle 37
The relationship is:
[tex]cos(37) = \frac{11}{x}[/tex]
i.e.
[tex]cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]
Make x the subject
[tex]x = \frac{11}{cos(37)}[/tex]
[tex]x = \frac{11}{0.7986}[/tex]
[tex]x = 13.7741[/tex]
[tex]x = 13.8[/tex] -- approximated
can someone please help me on Carnegie??
Answer:
First tell me what's Carnegie
OMG PLZ HELP ME! it is due tomorrow.....!
Step-by-step explanation:
Dilations do not change your angles, so although the length does change, your angles will not. So for your answer, the angles will be the exact same.
For the length, all you have to do is multiply each side by 5/2.
8: Multiplied by 5/2 is 20
9: Multiplied by 5/2 is 22.5
7: Multiplied by 5/2 is 17.5
The lengths are getting larger because they're being dilated by a number greater than 1.
I hope this helps :)
Answer:
Answers bellow hope I helped
Step-by-step explanation:
A)Each angle is the SAME becouse we are just making the triangle larger but the angles stay the same so:
Z' = 50°
X' = 70°
Y' = 60°
B)You have to multiply each of the sides by your scale factor so:
Side X'Y' = 7 x 5/2= 17.5
Side X'Z' = 8 x 5/2 = 20
Side Z'Y' = 9 x 5/2 = 22.5
A refrigerator was on sale at the appliance store for 20% off.Marcus received a coupon from the store for an additional 30% off any current price in the store. If he uses the coupon to buy the refrigerator , the price would be $487.20 before taxes.What was the original price?
Answer:
$870
Step-by-step explanation:
let $x be original price
x(0.8)(0.7) = 487.2
x= 487.2/0.8/0.7
x=870

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that Zachary bought some belts online for $56. He used a coupon code to get a 30% discount.
Given the website also app lied a 15% processing fee to the price after the discount.
Discount = 30% of original price
= 0.3 x $56
=16.80

Answer:
-4 < n ≤ 5
Step-by-step explanation:
Since the left inequality is an open circle and going to the right, the sign will be >
Since the right inequality sign is a closed circle and is going left, the sign would be ≤
The open circle ends at -4 so, n > -4
The closed circle ends at 5 so, n ≤ 5
You combine them and it looks like this:
-4 < n ≤ 5

Answer:
352 sq. inches
Step-by-step explanation:
32 x 22 = 704
704 / 2 = 352
Answer:
352 sq. inches
Step-by-step explanation:
The area of a triangle is found by the formula 1/2bh
aka 1/2 of base times height
the height is 22 and the base is 32 so we multiply 22 by 32
We get 704 but not the end we have to multiply that by 1/2 or divide by 2
Do that and you get 352
b=32 h=22
22*32=704
704/2 or 704*1/2 = 352

Which equation doesn't belong? Explain your reasoning. 1. 1/4x = 27 2. 3x = 36 3. 3/4x = 9 4. 4x = 48
Answer:
1/4x = 27
Step-by-step explanation:
Given the equations :
1.)
1/4x = 27 ;
x/4 = 27
x = 27 * 4
x = 108
2.)
3x = 36
Divide both sides by 3
x = 36/3
x = 12
3.)
3/4x = 9
3x / 4 = 9
3x = 9*4
3x = 36
x =. 36/3
x = 12
4. 4x = 48
x = 48/4
x = 12
All other equations equal to 12 except (1)

30 inch. by 18 inch 360 inch²

18 inch. by 15 inch 180inch²
Step-by-step explanation:
The answers are given in the same line .
Actual 1/3 2/3
30 inch. by 12 inch 120 inch² 240 inch²
30 inch. by 18 inch 180 inch² 360 inch²
12 inch. by 15 inch 60 inch² 120inch²
18 inch. by 15 inch 90 inch² 180inch²
We find the areas and multiply by 2/3 to get the answers
30 * 12= 360 inch²
2/3 * 360 = 240 inch²
30 * 18= 540 inch²
2/3 * 540 = 360inch²
12 * 15= 180 inch²
2/3 * 180 = 120 inch²
18 * 15= 270 inch²
2/3 * 270 = 180inch²
Rewrite the following expression with rational exponents. 3 sq root -27x^2 y^7
Show your work
Answer:
Step-by-step explanation:
The square root is possible only if y≤0
if y>0 the expression lose meaning, in fact (-)(+)(+) = (-) and a square root of a negative number doesn’t exist. x^2 is a square so it is ever positive if x is not 0
if y≤0 can be rewritten as:
3(-27x^2y^7)^1/2
or if we want simplify the expression:
[tex]3 \sqrt{3^2 * (-3) * x^2 * y^6 * y} = 3^2|x||y|^3 (-3y)[/tex] ^1/2
we have to put the symbol of absolute value between x and y because a x^2 and y^6 are numbers that are ever positive, while x and y^3 can be also negative. Thanks to the simbol of absolute value we can “force” them to be positive

Chip’s favourite snack food is Dingles potato chips. He enjoys layering 3 chips together to make a stack of interesting flavours. If he only has Regular flavoured Dingles, there is only one way to stack the three chips. That is Regular, Regular and Regular which can be written as rrr. The order in which the chips are layered does not matter. For example, if we have Regular and BBQ Dingles then the stack BBQ, BBQ and Regular (bbr) is the same as BBQ, Regular and BBQ (brb).
a) If he has Regular and BBQ flavoured Dingles, list all the different stacks of 3 chips he can make.
b) If he has three flavours of chips, Regular, BBQ, and Vinegar, list all the different stacks of 3 chips he can make.
c) If he adds a fourth flavour, Ketchup, list all the different stacks of 3 chips he can make.
