If you have 8 apples and your friend Joe gives you 2 more, you then have 10 apples.
∠A and ∠ B ∠B are supplementary angles. If m ∠ A = ( 7 x + 15 ) ∘ ∠A=(7x+15) ∘ and m ∠ B = ( x + 13 ) ∘ ∠B=(x+13) ∘ , then find the measure of ∠ A ∠A.
Answer:
∠A = 148°
∠B = 32°
Step-by-step explanation:
We know that ∠A and ∠B are supplementary angles, this means that:
∠A + ∠B = 180°
And we also know that:
∠A = (7x + 15)°
∠B = (x + 13)°
Then we have a system of 3 equations.
To solve it, we can replace the second and third equations into the first one, and get:
(7x + 15)° + (x + 13)° = 180°
Now we can solve this for x, but first, let's remove the degree sign so it is easier to work:
7x + 15 + x + 13 = 180
(7 + 1)*x + 28 = 180
8*x = 180 - 28 = 152
x = 152/8 = 19
Now that we know x, we can find the values of ∠A and ∠B
∠A = (7x + 15)° = (7*19 + 15)° = 148°
∠B = (x + 13)° = (19 + 13)° = 32°
the quantity of x plus 16 all over 3 = 3x
Answer:x= 2
Step-by-step explanation:
X+16/3= 3x
3(x+16/3)=3(3x) [in order to cancel out the divided by 3]
X+16=9x
16=8x
2=x

Example of standard notation
45,000,000 ---> 4.5000000
Follow the example using the number 45,000,000. In this case, move the decimal point until it is after the first non-zero number. If moving to the left, go one additional space so that there is a whole number on the left and a mantissa on the right.
107⁷
The number of spaces the decimal point was moved becomes the exponent. If it was moved right, the exponent is negative. If left, the exponent is positive. If the exponent is zero, scientific notation isn't needed.
45,000,000 = 4.5 x 10⁷
Answer:
9)2445

I hope It's Right
Step-by-step explanation:
Okay so I think by "standard notation" it means Regular notation/standard form so I'm answering in Regular notation/standard form. If I'm WRONG and It's asking for Scientific notation, tell me I can answer these in scientific notation also.

For the circle centered at the origin with radius 4 and equation x^2+y^2=16, find dx/dt at the first quadrant point where x=2 if dy/dt=-3 at that instant.
Answer:
dx/dt = 12
Step-by-step explanation:
Given the equation of a circle expressed as:
x²+y² = 16
Differentiate the expression with respect to x
2x dx/dt + 2y dy/dt = 0
Given
x = 2
dy/dt = 3
Required
dx/dt
Substitute the given parameters into the resulting differential equation
2x dx/dt + 2y dy/dt = 0
2 dx/dt + 2(4) (-3) = 0
y = 4 since the radius is 3,
2 dx/dt - 24 = 0
2 dx/dt = 24
dx/dt = 24/2
dx/dt = 12
Using implicit differentiation, it is found that:
[tex]\frac{dx}{dt} = 4 + 3\sqrt{3}[/tex]
The equation of the circle is:
[tex]x^2 + y^2 = 16[/tex]
We are given x = 2, then:
[tex]2^2 + y^2 = 16[/tex]
[tex]y^2 = 12[/tex]
[tex]y = \pm \sqrt{12}[/tex]
First quadrant, thus, positive:
[tex]y = \sqrt{12}[/tex]
[tex]y = 2\sqrt{3}[/tex]
Applying implicit differentiation, we have that:
[tex]2x\frac{dx}{dt} + 2y\frac{dy}{dt} = 16[/tex]
We are given that [tex]frac{dy}{dt} = -3[/tex], then:
[tex]2(2)\frac{dx}{dt} - 12\sqrt{3} = 16[/tex]
[tex]4\frac{dx}{dt} = 16 + 12\sqrt{3}[/tex]
[tex]\frac{dx}{dt} = \frac{16 + 12\sqrt{3}}{4}[/tex]
[tex]\frac{dx}{dt} = 4 + 3\sqrt{3}[/tex]

solve the inequality and graph the solution on the line provided.
Answer:
When solving inequalities you want to first group all like terms, so you'd first add 8 to both sides, and get rid of the extra number on the left side.
7x ≤ -7
Then you'd isolate the variable, so you should divide both sides by 7.
x ≤ -1
When graphing the equation the solution set includes -1 so you would put a closed circle (filled in). The variable "x" is less than and equal to -1 so you would put the arrow facing left <----.

first convert fraction to percentage, then into a decimal.
The line in a fraction that separates the numerator and denominator can be rewritten using the division symbol. So, to convert a fraction to a decimal, divide the numerator by the denominator. If required, you can use a calculator to do this. This will give us our answer as a decimal.
If x varies directly as y, and x is 10 when y is 150, find the constant of variation. A. StartFraction 1 Over 150 EndFraction c. StartFraction 1 Over 15 EndFraction b. StartFraction 1 Over 1500 EndFraction d. One-fifth Please select the best answer from the choices provided A B C D
Answer:
c. StartFraction 1 Over 15EndFraction
= 1/15
Step-by-step explanation:
If x varies directly as y
This is expressed as:
x ∝ y
Constant of variation = k
Hence,
x = ky
To find k, divide both sides by y
x/y = ky/y
k = x / y
x is 10 when y is 150
Therefore,
k = 10/150
k = 1/15
Constant of variation = 1/15
what is the slope of the line perpendicular to the lone whose equation is 2x+2y=28
Answer:
The slope of the line perpendicular to the line whose equation is 2x + 2y = 28 is -x.
Step-by-step explanation:
You first isolate y, then divide 2 on both sides. This gives you the equation y = x + 14. To find a slope perpendicular to the line, simply use the negative integer of x, which is -x. The slope of the line perpendicular to the line given is -x.

/point) 1: The food bank has 110.9 pounds or 1,774.4 ounces of chicken. To the
nearest
whole number, how many servings of chicken does this provide? Show your work
Answer:
The total number of servings of chicken the food bank can provide = 70 servings
Step-by-step explanation:
The given information from the table are;
The number of chicken contained in the main course of a serving of food = 2
The mass of each chicken served by the food bank = 12.6 oz
The quantity of chicken the food bank has = 110.9 pounds (1,774.4 ounces of chicken)
Therefore we have;
The mass of chicken per serving = 2 × 12.6 = 25.2 oz/serving
The total number of servings of chicken the food bank can provide = (The quantity of chicken the food bank has)/(The mass of chicken per serving)
∴ The total number of servings of chicken the food bank can provide = (1,774.4 oz)/(25.2 oz/serving) ≈ 70.413
Given that the servings are in whole numbers, we have;
The total number of servings of chicken the food bank can provide = 70 servings, to the nearest whole number.
