Answer:

The largest angle needed is [tex]95.1^{o}[/tex].

Step-by-step explanation:

To determine the larges angle as required, let us apply the cosine rule.

[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - 2ab Cos C

Since in triangles, the longest side is opposite to the largest angle, then;

[tex]15^{2}[/tex] = [tex]8^{2}[/tex] + [tex]12^{2}[/tex] - 2(8 x 12) Cos θ

225 = 64 + 144 - 192 Cos θ

225 = 208 - 192 Cos θ

192 Cos θ = 208 -225

192 Cos θ = -17

Cos θ = [tex]\frac{-17}{192}[/tex]

Cos θ = -0.08854

θ = [tex]Cos^{-1}[/tex] -0.08854

  = 95.07962

θ = [tex]95.1^{o}[/tex]

The largest angle needed is [tex]95.1^{o}[/tex].

Answer:

3 grams are in one chicken wing

Step-by-step explanation:

Set up an equation:

Variable x = grams per 1 chicken wing

1000/3000 = 1/x

Cross multiply

1000 × x = 3000 × 1

1000x = 3000

Divide both sides by 1000 to isolate the variable x

x = 3

Answer:

3

Step-by-step explanation:

3000/1000=3

Answer:

Step-by-step explanation:

2x2+5x−10=x2+4

Step 1: Subtract x^2+4 from both sides.

2x2+5x−10−(x2+4)=x2+4−(x2+4)

x2+5x−14=0

For this equation: a=1, b=5, c=-14

1x2+5x+−14=0

Step 2: Use quadratic formula with a=1, b=5, c=-14.

x=

−b±√b2−4ac

x=

−(5)±√(5)2−4(1)(−14)

x=2 or x=−7

Answer:

x=2 or x=−7

Answer:

x = 2 or x= -7

Step-by-step explanation:

We can use factorisation to solve this.

First, we shift all the variables to one side (see attachement)

Then, we need to find the value of x, which multiples to give -14 and adds together to give 5.

7 - 2 = 5

and 7 x (-2) = -14.

Now we factorize (group into brackets) to find the values of x.

We solve for x to find the final answer.

104+76=180 and a circle is 360

- Thx for the points have a nice day! ^ω^

Answer:

A. 76

B. 256

Step-by-step explanation:

DF is a diameter so that means the right side of the

circle measure 180 degrees. Angle DGE measures 104, since that the central angle that means Arc DE measures 104 also.

Using arc addition, part of the right side measure 104 so that means the remaining arc must add up to 180.

[tex]104 + x = 180[/tex]

[tex]x = 76[/tex]

Arc EF measure 76.

2. A circle has 360 degrees in it. We are asked to find the measure of the circle expect the Arc ED.

Arc ED measures 104 so

[tex]360 - 104 = 256[/tex]

Answer:

[tex]\text{log}_a(1.5^{-1})=\frac{-9}{5}[/tex]

Step-by-step explanation:

Given;

[tex]\text{log}_a(2)=\frac{1}{2}[/tex]

[tex]\text{log}_a(3)=5[/tex]

By using logarithmic properties,

[tex]\text{log}_a(2)-\text{log}_a(3)=\frac{1}{2}-5[/tex]

[tex]\text{log}_a(\frac{2}{3})=\frac{1}{2}-5[/tex]

[tex]\text{log}_a(\frac{1}{\frac{3}{2}})=\frac{1}{2}-5[/tex]

[tex]\text{log}_a(\frac{1}{1.5})=\frac{1}{2}-5[/tex]

[tex]\text{log}_a(1.5^{-1})=\frac{1-10}{5}[/tex]

[tex]\text{log}_a(1.5^{-1})=\frac{-9}{5}[/tex]

Answer:

The answer is "2 years".

Step-by-step explanation:

Given:

[tex]\to P(t) = 493\times4^{\frac{t}{2}}[/tex]

when t=0

[tex]P(0) = 493\times4^{\frac{0}{2}}\\\\[/tex]

        [tex]= 493\times4^0\\\\= 493\times 1\\\\= 493 \\[/tex]

 Calculating the quadrupling time:    

[tex]\to P(t) = 4 \times P(0) \\\\[/tex]

            [tex]= 4\times 493 \\\\= 1972[/tex]

 Solving  

[tex]\to 1972= 493\times4^{\frac{t}{2}} \\\\\to 4 = 4^{\frac{t}{2}}\\\\\to \frac{t}{2} = 1\\\\\to t = 2\ years \\\\[/tex]

Answer:

y = 6.5 units

Step-by-step explanation:

Let L be the length of sides of the square.

Given the following data;

Perimeter of square = 8y - 12

Area of square = 100 square units

To find the value of y;

Area of a square = L²

Substituting into the formula, we have;

100 = L²

L = √100

L = 10 units

Mathematically, the perimeter of a square is given by the formula;

Perimeter of a square = 4L

Substituting into the formula, we have;

8y - 12 = 4*10

8y - 12 = 40

8y = 40 + 12

8y = 52

y = 52/8

y = 6.5 units

Answer:

20cm^3

Step-by-step explanation:

The volume of a rectangular prism is just the 3 values multiplied by each other. So that would be 6x5x2/3 = 20cm^3

Answer:

166°

Step-by-step explanation:

Supplementary angles have a sum of 180 degrees

That being said, we can find the measure of the missing angle by subtracting the measure of the given angle by 180

(the giving angle having a measure of 14°)

so missing angle = 180 - 14

180 - 14 = 166

Hence, the measure of the second angle 166°

Answer:

10.8

Step-by-step explanation:

The value of x is 5.26.

Trigonometry is the branch of mathematics that deals with the relationship between ratios of the sides of a right-angled triangle with its angles. The ratios used to study this relationship are called trigonometric ratios, namely, sine, cosine, tangent, cotangent, secant, cosecant.

There are basic six ratios in trigonometry that help in establishing a relationship between the ratio of sides of a right triangle with the angle. If θ is the angle in a right-angled triangle, formed between the base and hypotenuse, then

sin θ = Perpendicular/Hypotenuse

cos θ = Base/Hypotenuse

tan θ = Perpendicular/Base

The value of the other three functions: cot, sec, and cosec depend on tan, cos, and sin respectively as given below.

cot θ = 1/tan θ = Base/Perpendicualr

sec θ = 1/cos θ = Hypotenuse/Base

cosec θ = 1/sin θ = Hypotenuse/Perpendicular

Given:

H= 12

angle= 26°

Using Trigonometry

sin 26 = B/ H

0.4383= x/ 12

x= 5.26

Hence, the value of x is 5.26

Step-by-step explanation:

Please refer to the attachment

The radical expression √x/2 e is equivalent to the given product, which is the correct option(C).

Any expression that contains a radical symbol is considered a radical expression. Unknown variables, numbers, and arithmetic operators make up a radical expression. It contains no equality or inequality symbols.

To find the square roots, cubic roots, and higher, radical symbols are used. For example, √7, √6, and √11 are in the radial form.

The radical expression is given in the question, as follows:

√(3/x)·√(x²/12)

Combine the term in radicals of the above expression,

√[(3/x) × (x²/12)]

Reduce the likewise variables in the expression,

√(x/4)

Apply the square root property, and we get

√x/2

Thus, the radical expression √x/2 e is equivalent to the given product.
