Answer:

An inscribed angle is defined as the half of its intercepted arc. It's important to notice that the subtended arc by angle C is 180°, because it's have of the total arc length.

[tex]C=\frac{1}{2} (180\°)=90\°[/tex]

Therefore, angle C is a right angle.

Now, in the image attached you can notice that triangle ABC has one acute angle of 46° and one right angle. We already know that the sum of all three internal angles of a triangle must be equal to 180°.

[tex]90\° + 46\° + B=180\°\\B=180\° - 46\° - 90\° = 44\°[/tex]

On the other hand, notice that the diameter of the circle represents the hypothenuse for the right triangle. To find the hypothenuse, we need to know the length of one leg at least.

Therefore, there's no enough information to find the hypothenuse, which implies we can't find the diameter/radius.

Step-by-step explanation:

Answer:

a=16 b =10 or any other combination that gives 160

a = 20 b=8

a = 32 b = 5

Step-by-step explanation:

The area of a triangle using the lengths of two sides and the sine of the included angle is ½ ab sin C  where a and b are sides and C is the angle.

A =40 = 1/2 ab sin 30°

sin 30° = 1/2 so

40 = 1/2*ab*1/2

40 =1/4 ab multiply each side by 4

160 = ab

any combination of sides that gives you 160 will work

Let's check if a=16 b =10

A = 1/2*16*10 sin 30°

A = 1/2*160*1/2

A = 40

Step-by-step explanation:

The area of a parallelogram is b * h, where b is the base and h is the height. We'll call the height x and the base x + 4, and we know that this is equal to 45.

x (x + 4) = 45

x² + 4x = 45

x² + 4x - 45 = 0

(x + 5)(x - 4) = 0

x = -5, 4 → x = 4 (no negative sides)

Therefore, base is 8 and height is 4. Hope this helps!

Answer:

x=9

Step-by-step explanation:

48-3=45

5x=45

45/5=9

The value of x in the given inequality will be equal or smaller than 9,

x ≤ 9

A relationship between two expressions or values that are not equal to each other is called inequality.

Given is an inequality 5x + 3 ≥ 48

Solving for x,

5x + 3 ≥ 48

Subtract 3 from both side, that will reverse the sign,

5x ≤ 45

Divide both sides by 5,

x ≤ 9

Hence, the value of x will be equal or smaller than 9, x ≤ 9

Answer:

mDBC = 341 °

Step-by-step explanation:

Arc DBC is almost the whole circle, if you were to exclude the degree measure of minor arc DC; which is, in other words m∠ DPC

Now by Vertical Angles Theorem:

m ∠ DPC = m∠ APB, ⇒ provided BD, and AC are diameters

m∠ DPC = 19°

This would mean ⇒

mDBC = 360 - m∠ DPC,

mDBC = 360 - 19,

mDBC = 341 degrees ( ° )

Answer:

1 / 663

Step-by-step explanation:

First, let's find the total number of ways you can pick 2 cards from the deck. This is 52 * 51 = 2652 because there are 52 cards available for your first pick, and after you pick one, you'll have 51 left for your second pick.

There are 4 5's  (one for every suite) and only 1 Queen of Hearts in a deck of cards. Therefore, the total number of successful outcomes will be 4 * 1 = 4.

The probability of picking a 5 and then a Queen of Hearts is 4 / 2652 =

1 / 663. Hope this helps!

Answer:

49 / 9π + 16

Step-by-step explanation:

So 110 / 360 = 11 / 36

The circumference of the circle is 16π

11 / 36 * 16 = 44 / 9π

44 / 9π + 8 + 8 is the answer since you gotta add the sides.

This might be wrong so check my steps.

Answer:

f(x)=x²-2x-2

Step-by-step explanation:

f(x)=ax²+bx+c

f(0)=-2 => c= -2

f(1)= -3=> a+b-2=-3; a+b=-1

f(2)= -2; 4a+2b-2=-2; 4a+2b=0; 2a+b=0

a+b=-1 and 2a+b=0

2a+b-(a+b)=0+1=> a=1

2+b=0=> b=-2

f(x)=x²-2x-2

We have been given that the quadratic equation [tex]y=-0.5x^2+4x+10[/tex] models the path of a heavy ball through the air, where y represents the height in feet and x represents time in seconds. We are asked to find the time when ball will hit the ground.

The ball will hit the ground, when height of ball above ground will be 0. So we will equate our given quadratic equation with 0 and solve for x.

[tex]-0.5x^2+4x+10=0[/tex]

We will use quadratic formula to solve our given problem.

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex], where

b = Coefficient of x term,

a = Coefficient of [tex]x^2[/tex] term,

c = Constant.

[tex]x=\frac{-4\pm\sqrt{(-4)^2-4(-0.5)(10)}}{2(-0.5)}[/tex]

[tex]x=\frac{-4\pm\sqrt{(16+20}}{-1}[/tex]

[tex]x=\frac{-4\pm\sqrt{36}}{-1}[/tex]

[tex]x=\frac{-4\pm6}{-1}[/tex]

[tex]x=\frac{-4+6}{-1}, x=\frac{-4-6}{-1}[/tex]

[tex]x=\frac{2}{-1}, x=\frac{-10}{-1}[/tex]

[tex]x=-2,x=10[/tex]

Since time cannot be negative, therefore, the ball will hit the ground after 10 seconds.

Answer:

yes, 1.5

Step-by-step explanation:

The ratios are equal. Then the triangle ΔRPQ is similar to the triangle ΔVAQ. And the ratio is 2: 1. Then the correct option is B.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

The ratio of the corresponding sides are given as,

RP / AV = PQ / AQ

6 / 3 = 8 / 4

2 = 2

The ratios are equal. Then the triangle ΔRPQ is similar to the triangle ΔVAQ.

Thus, the correct option is B.

Answer:

283.5 cm squared

Step-by-step explanation:

The surface area of a solid is basically just the sum of the areas of all the exterior sides. In this figure, we have 3 congruent triangles at the top, 3 congruent rectangles on the sides, and 1 triangle at the base. We need to find all these areas.

3 congruent triangles:

The area of a triangle is denoted by: A = (1/2) * b * h, where b is the base and h is the height.

Here, the base of one triangle is 10 and the height is 4. So:

A = (1/2) * b * h

A = (1/2) * 10 * 4 = 20

Since there are 3 such triangles, multiply 20 by 3:

20 * 3 = 60 cm squared

3 congruent rectangles:

The area of a rectangle is denoted by: A = lw, where l is the length and w is the width.

Here, the length is 6 and the width is 10, so:

A = lw

A = 6 * 10 = 60

There are 3 such rectangles, so multiply 60 by 3:

60 * 3 = 180 cm squared

1 base triangle:

Again we use the formula A = (1/2) * b * h for this area.

Here, the base is 10 and the height is 8.7, so:

A = (1/2) * b * h

A = (1/2) * 10 * 8.7 = 43.5 cm squared

Add all these together:

60 + 180 + 43.5 = 283.5 cm squared

The answer is thus 283.5 cm squared.

Answer:

283.5 cm²

Step-by-step explanation:

3 rectangles + 3 triangles on top + triangular base

3(10×6) + 3(½×10×4) + (½×10×8.7)

180 + 60 × 43.5

283.5 cm²
