33 degrees, 87 degrees, x=?

Answer:

3/42 or 1/14 if they have you reducing the number

Step-by-step explanation:

There are only 3 cans of black bean soup in the whole pantry. 3 is our numerator.

The denominator will be the total number of cans in the pantry, so

22 + 3 + 12 + 1 + 4 = 42

If you took a can of soup out of the pantry 42 times, 3 times it would be black bean soup

Explanation:

Triangle ABC is isosceles because sides AB and AC are the same length (both 8 units long).

The angles opposite these congruent sides are known as the base angles, and they are congruent angles.

So the base angles B and C are 30 degrees each.

----------

Next, we'll use the idea that for any triangle, the three angles always add to 180

So,

A+B+C = 180

A+30+30 = 180

A+60 = 180

A = 180-60

A = 120 degrees

Answer:

3,710 coupons

Step-by-step explanation:

You have to do 7,000-3,290 to get the answer, as 7,000 is the total number of coupons given, and 3,290 is the amount of coupons that was used.

7,000-3,290=3,710

Area of triangle + rectangle

Answer:

(3.442 ; 6.558)

Step-by-step explanation:

Given :

Mean score after patient is given the magnet treatment :

Mean score, xbar = 5

Standard deviation, s = 2.4

Sample size, n = 20

The confidence interval :

Mean ± margin of error

Margin of Error = Tcritical * standard error

The critical value at 95%, df = 20 - 1 = 19

Tcritical = 2.093 (T-student distribution)

The standard error = s/√n = 2.4 / √20 = 0.5367

The margin of error = 2.903 * 0.5367 = 1.558

The confidence interval :

Xbar ± Margin of error

5 ± 1.558

(3.442 ; 6.558)

Answer:

91.19

Step-by-step explanation:

From the given diagram;

BO = 2 BC

BO = 2(48)

BO = 96

To get AB, we will use the pythagoras theroem;

BO² = AB² + AO²

96² = AB² + 30²

9216 = AB² + 900

AB² = 9216 - 900

AB² = 8,316

AB = √8,316

AB = 91.19

Hence the length of AB is 91.19

Answer:

[tex]Base\ Area = 93ft^2[/tex]

Step-by-step explanation:

Given

[tex]Volume = 279ft^3[/tex]

[tex]Height =3ft[/tex]

Required

The base area

Volume is calculated as:

[tex]Volume = Base\ Area * Height[/tex]

This gives:

[tex]279= Base\ Area * 3[/tex]

Make Base Area the subject

[tex]Base\ Area = \frac{279}{3}[/tex]

[tex]Base\ Area = 93ft^2[/tex]

The whole set its self costs $159.

25% is being subtracted from $159.

To find the sales price just use your phone calculator or any calculator to subtract 25% from 159.

The sales price is $119.25.

Answer:

  (√5)/2

Step-by-step explanation:

Of the several ways I can think of to do this, using a graphing calculator is about the easiest. It shows the minimum to be ...

  f(1) = √1.25 = (√5)/2

__

Using the distance formula, you have ...

  f(x) = √((x -(-2))² +((x² +2)-5/2)²)

  f(x) = √(x² +4x +4 +x⁴ -x² +1/4) = √(x⁴ +4x +17/4)

The minimum is found where the derivative is zero.

  f'(x) = (2x³ +2)/√(x⁴ +4x +17/4) = 0

  x³ = -1 . . . . . f'(x) is zero when the numerator is zero

  x = -1 . . . . . cube root

Then the minimum value of f(x) is ...

  f(-1) = √(x⁴ +4x +17/4) = √((-1)⁴ +4(-1) +17/4) = √(1 -4 +17/4) = √(5/4)

  f(-1) = (√5)/2 . . . . minimum value of f(x)

__

The graph shows f²(x) in red and its minimum of 1.25 = 5/4. The curve (x, x²+2) and the point (-2, 5/2) are also shown, for reference. (The slope of the curve at x=-1 is -2, and the normal to the curve at that point has slope 1/2. The normal goes through the point (-2, 5/2), consistent with f(x) being a minimum at x=-1.)

Answer:

A. It increased both her intensity and her workout time.

Step-by-step explanation:

A. It increased both her intensity and her workout time.

B. It decreased her intensity but increased her workout time.

C. It increased her intensity but decreased her workout time.

D. It decreased both her intensity and work out time

Last week = 4 miles per day

This week = 5 miles per day

Intensity refers to how hard one exercises.

Workout time refers to how long one exercises the body.

By adding a mile, she has increased how hard she exercises her body (intensity))

And also increased how long she exercises the body (workout time) because the time she spent on 5 miles per day is more than time spent on 4 miles per day

[tex]Width = x^2 - 8[/tex]

Step-by-step explanation:

Given

[tex]L = 16 + W[/tex]

[tex]Area = x^4 - 64[/tex]

Required

An expression for the width

We have:

[tex]Area = x^4 - 64[/tex]

Express as difference of two squares:

[tex]Area = (x^2 + 8)(x^2 - 8)[/tex]

For all acceptable values of x,

[tex]x^2 + 8>x^2 - 8[/tex]

So:

[tex]Length = x^2 + 8[/tex]

[tex]Width = x^2 - 8[/tex]

Answer:

15.9 mm²

Step-by-step explanation:

We solve using Area of the circle formula

Area of a circle = πr²

Diameter of his friend's wand = 4.5mm

Radius = 4.5mm/2

= 2.25 mm

How much wire did his friend need to make the circular part of his wand? Use 3.14 for π

= 3.14 × (2.25mm)²

= 15.89625 mm²

Approximately = 15.9 mm²

180° - 103° = 77°

x = 77°

Answer:

Answer:

P(A) = 1/2

Step-by-step explanation:

The question seems incomplete, I assume that we want to find the probability of event A.

Here we have a fair six-sided dice, so each one of the six numbers has exactly the same probability of being rolled.

Such that the possible outcomes of rolling the dice is:

{1, 2, 3, 4, 5, 6}

Now we define event A as rolling an even number.

The possible outcomes such that the event A is true are the even numbers:

{2, 4, 6}

So we have 3 outcomes out of 6.

Then the probability of rolling an even numbers, is just the quotient between the number of outcomes of even numbers (3) and the total number of outcomes (6).

Then:

P(A) = 3/6 = 1/2 = 0.5
