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°

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

This is The Answer! Solutions: x=2.

Step-by-step explanation:

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.

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.

Answer:

Each question was worth 5 points.

Step-by-step explanation:

If every question had the same worth, then that would be easier to calculate.

First divide the points he lost by how many questions.

20 ÷ 4 = 5

Now we have it! Each question is worth 5 points!

But if you want to find how many questions in total the test had, we can do that too!

100 ÷ 5 = 24

The test had 24 questions!

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.

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]

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  <----.
