10 1. Use The Image Below To Answer The Following Questions: Solve For The Measurement Of A. B. Solve

Answers

Answer 1

Answer:

see explanation

Step-by-step explanation:

(a)

the sum of the 3 angles in the triangle = 180° , then

∠ A = 180° - 90° - 48° = 180° - 138° = 42°

(b)

using the tangent ratio in the right triangle

tan48° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{y}{10}[/tex] ( multiply both sides by 10 )

10 × tan48° = y , then

y ≈ 11.1 units ( to the nearest tenth )

(c)

using the cosine ratio in the right triangle

cos48° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{10}{x}[/tex] ( multiply both sides by x )

x × cos48° = 10 ( divide both sides by cos48° )

x = [tex]\frac{10}{cos48}[/tex] ≈ 14.9 units ( to the nearest tenth )

A triangle has a perimeter of 77 cm. One side of the triangle is double the base. The other side is quadruple the base. What are the 3 side lengths? Show your work

Answers

The three sides of the triangles are 11 cm, 22cm, and 44cm.

What is the perimeter of a triangle?

The perimeter of the triangle can be calculated by the sum of all the three sides of the triangle.

A triangle has a perimeter of 77 cm.

Let the side of the triangle be x, y, and the base z.

One side of the triangle is double the base.

x = 2z

The other side is quadruple the base.

y = 4z

The perimeter

X + y + z = 77

or

2z + 4z + z = 77

7z = 77

z = 11

So, the length of base z is 11 cm.

The other sides as

x = 22

y = 44

Therefore,The three sides of the triangles are 11 cm, 22cm, and 44cm.

Given the following function: y=x^2+10x+25 Using your knowledge of discriminants, how many solutions does this function have?

Answers

Answer:

One solution

Step-by-step explanation:

Given function:

y = x² + 10x + 25

This is a quadratic function.  

A quadratic equation has:

Two solutions if discriminant is positive;One solution if discriminant is zero;No solution if discriminant is negative

Find the discriminant of the given function:

D = b² - 4ac = 10² - 4*1*25 = 100 - 100 = 0

This function has one solution since its discriminant is zero.

Answer:

one real solution

Step-by-step explanation:

Discriminant

[tex]b^2-4ac\quad\textsf{when}\:ax^2+bx+c=0[/tex]

[tex]\textsf{when }\:b^2-4ac > 0 \implies \textsf{two real solutions}[/tex]

[tex]\textsf{when }\:b^2-4ac=0 \implies \textsf{one real solution}[/tex]

[tex]\textsf{when }\:b^2-4ac < 0 \implies \textsf{no real solutions}[/tex]

Given function:

[tex]y=x^2+10x+25[/tex]

Therefore:

[tex]a = 1[/tex][tex]b = 10[/tex][tex]c = 25[/tex]

Substitute the given values into the discriminant:

[tex]\implies 10^2-4(1)(25)=0[/tex]

As the discriminant equals zero, there is one real solution.

How many inches around is the border if the diameter of the pizza is 8 inches?

Answers

Answer:

25.12

Step-by-step explanation:

Since it says around the pizza, we can assume it means circumference.

So, the formula to find circumference is C=2πr.

We have a diameter which is 8. We know that radius is half of the diameter. So, half of 8 is 4.

Now that we have the radius we can plug in the numbers for the formula C=2πr.

C=2πr

C=2*3.14*4

C=25.12

your answer is 25.12 inches.

300% of 7 is what percent of 42?
A. 30%
B. 50%
C. 60%
D. 12.5%

Answers

Answer:

B. 50%

Step-by-step explanation:

Step by step by me I guess

The solution is , B) 50% of 42 is 300% of 7.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here. we have,

given that,

300% of 7

we have to that is what percent of 42.

now, we know,,

300% of 7 = 300 * 7 /100

[300% is the same as 3. So to find 300% of 7 , 3 times 7 and get 21.]

i.e. 300% of 7 = 3* 7

                       = 21

Now we need to find _% times 42 = 21.

let, it = x

now,

Divide 21/42 to get 0.5.

This is the same thing as 50%.

so, we get,

50% of 42 = 21

i.e. 300% of 7 = 50% of 42

Hence, The solution is , B) 50% of 42 is 300% of 7.
