Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180.
6y - 5 + 10y - 41 + 12x + 22 = 180
12x + 16y - 24 = 180
12x + 16y = 204
3x + 4y = 51 Equation 1
Two sides are congruent, so opposite angles are congruent.
6y - 5 = 10y - 41
36 = 4y
4y = 36 Equation 2
Equations 1 and 2 form a system, of equations.
3x + 4y = 51
4y = 36
Solve the second equation for y.
y = 9
Substitute 9 for y in the first equation.
3x + 4(9) = 51
3x + 36 = 51
3x = 15
x = 5
Answer: x = 5; y = 9

Julio bought 3 bags of cat food and 4 bags of dog food for $43.00 Sandy bought 3 bags of cat foot and 6 bags of dog food for $54.00. How much is one bag of cat food and one bag of dog food?
Answer:
$12.50
Step-by-step explanation:
c is cat food d is dog food
3c + 4d = 43
3c + 6d = 54
subtract those to get
2d = 11
d = 5.50
3c + 2d = 3c + 22 = 43
3c = 21
c = 7
c+d = 7 + 5.50 = 12.50
Ann has an empty cup and add 1 ounce of water per second. Bob has 12 ounces of water and drinks 2 ounces per second. After how many seconds will they have the same amount of water
Answer:
4 seconds
Step-by-step explanation:
Given
Ann has an empty cup and add 1 ounce of water per second
let the number of seconds required to fill the cup be x
let the total be y
in x seconds Ann will have x ounces of water in the cup.
so the total amount of water in Ann's cup will be
[tex]y=x-----------1[/tex]
Bob has 12 ounces of water and drinks 2 ounces per second
also, let the number of seconds required to empty the cup be x
let the total be y
[tex]y= 12-2x--------------2[/tex]
Step two:
equate the two equations above and solve for x
[tex]x=12-2x[/tex]
collect like terms
[tex]x+2x=12\\\\3x=12[/tex]
divide both sides by 3
[tex]x=12/3\\\\x= 4 seconds[/tex]
Therefore, after about 4 seconds Ann and Bob's cup will have the same amount of water

And don't do an answer that's not helpful, I report when people do that
Answer:
The answer is 72
First you find E=180-130=50
Then you add all the angles and subtract from 360
102+100+50=252
360-252=108
then you do 180-108=72
Answer:
72 degrees.
Step-by-step explanation:
The first step would be finding E. We know that a straight line would be 180 degrees. Therefore, we would subtract 180-130=50.
100+102+50+b=360
252+b=360
-252 -252
b=108
Then we would subtract 180-108=72.
Therefore, because it is the angle we are looking for.
Your answer would be the measure of angle ABC is 72 degrees.

Surface area what the surface area of a rectangle 8in 10 3/4ths and 5 1/2
Answer:
The surface area of the cuboid is 378 [tex]\frac{1}{4}[/tex] square inches.
Step-by-step explanation:
A cuboid is a shape which has six surfaces formed from a rectangle. The surface area of a cuboid is the sum of all its individual ares of each surface.
Given the following dimensions of the cuboid:
length = 10 3/4 in = [tex]\frac{43}{4}[/tex] in
width = 8 in
height = 5 1/2 in = [tex]\frac{11}{2}[/tex] in
Since the opposite surface of a cuboid are the same, then;
Area of the 1st surface = length x width
= [tex]\frac{43}{4}[/tex] x 8
= 86 square inches
Area of the 2nd surface = width x height
= 8 x [tex]\frac{11}{2}[/tex]
= 44 square inches
Area of the 3rd surface = length x height
= [tex]\frac{43}{4}[/tex] x [tex]\frac{11}{2}[/tex]
= [tex]\frac{473}{8}[/tex]
= 59 [tex]\frac{1}{8}[/tex] square inches
Surface area of the cuboid = 2 x 86 + 2 x 44 + 2 x [tex]\frac{473}{8}[/tex]
= 172 + 88 + 118.25
= 378.25
Surface area of the cuboid = 378 [tex]\frac{1}{4}[/tex] square inches

Answer:
x + y + (y - 18) = 180
x = 86
y = 56
Step-by-step explanation:
The sum of the measures of the angles of a triangle equals 180.
x + y + (y - 18) = 180
x + 2y - 18 = 180
x + 2y = 198
x + 2y = 198
3x - 5y = -22
-3x - 6y = -594
(+) 3x - 5y = -22
----------------------------
-11y = -616
y = 56
x + 2y = 198
x + 2(56) = 198
x + 112 = 198
x = 86

Jade used Fraction 3 over 4 yard of fabric to make a scarf. Can she make 2 of these scarves with Fraction 1 and 4 over 5 yards of fabric, and why? No, because the quotient of Fraction 3 over 4 ÷ Fraction 1 and 4 over 5 is 1 and 7 over 20 No, because the quotient of Fraction 1 and 4 over 5 ÷ Fraction 3 over 4 is 1 and 7 over 20 Yes, because the quotient of Fraction 3 over 4 ÷ Fraction 1 and 4 over 5 is 2 and 2 over 5 Yes, because the quotient of Fraction 1 and 4 over 5 ÷ Fraction 3 over 4 is 2 and 2 over 5
Answer:
Yes, because the quotient of Fraction 1 and 4 over 5 ÷ Fraction 3 over 4 is 2 and 2 over 5
Step-by-step explanation:
Jade used Fraction 3 over 4 yard of fabric to make a scarf. Can she make 2 of these scarves with Fraction 1 and 4 over 5 yards of fabric, and why?
Representing the above expression Mathematically
3/4 yard = 1 scarf
1 4/5 yards of fabric = x
Cross Multiply
3/4x = 1 4/5 × 1
x = 9/5/ 3/4
x = 9/5 ÷ 3/4
x = 9/5 × 4/3
x = 12/5 scarves
x = 2 2/5 scarves
Hence, the correct option is :
Yes, because the quotient of Fraction 1 and 4 over 5 ÷ Fraction 3 over 4 is 2 and 2 over 5
Answer:
Yes, because the quotient of Fraction 1 and 4 over 5 ÷ Fraction 3 over 4 is 2 and 2 over 5

The height of a rocket x seconds after it is launched from a hill that is 224 feet high is modeled by the function f (x) = -16x² + 80x + 224.
How long does it take the rocket to hit the ground?
It takes (?) seconds.
need asap thank you
Answer:
t = 7 seconds
Step-by-step explanation:
The height of a rocket x seconds after it is launched from a hill that is 224 feet high is modeled by the function :
f (x) = -16x² + 80x + 224
We need to find how long does it take the rocket to hit the ground. At that point,
f(x) = 0
[tex]-16x^2 + 80x + 224=0\\\\\dfrac{-16x^2}{16}+\dfrac{80x}{16}+\dfrac{224}{16}=0\\\\-x^2+5x+14=0\\\\-x^2+(7-2)x+14=0\\\\-x^2+7x-2x+14=0\\\\x(-x+7)+2(-x+7)=0\\\\(x+2)(-x+7)=0\\\\x=-2\ \text{and}\ x=7[/tex]
Neglecting -2. Hence, the rocket will take 7 seconds to hit the ground.
With reference to the figure, sin X equals?
1.) 0.250
2.)0.447
3.)0.894
4.)1
Answer:
3.) 0.894
Step-by-step explanation:
✔️First, find BD using Pythagorean Theorem:
BD² = BC² - DC²
BC = 17.89
DC = 16
Plug in the values
BD² = 17.89² - 16²
BD² = 64.0521
BD = √64.0521
BD = 8.0 (nearest tenth)
✔️Next, find AD using the right triangle altitude theorem:
BD = √(AD*DC)
Plug in the values into the equation
8 = √(AD*16)
Square both sides
8² = AD*16
64 = AD*16
Divide both sides by 16
4 = AD
AD = 4
✔️Find AB using Pythagorean Theorem:
AB = √(BD² + AD²)
AB = √(8² + 4²)
AB = √(64 + 16)
AB = √(80)
AB = 8.9 (nearest tenth)
✔️Find sin x using trigonometric ratio formula:
Reference angle = x
Opposite side = BD = 8
Hypotenuse = AB = 8.944
Thus:
[tex] sin(x) = \frac{opp}{hyp} = \frac{8}{8.944} = 0.894 [/tex] (nearest thousandth)
Answer:
Hey! The correct answer is the third option, I just took the test and it was correct
