Answer:

88.3 degrees

Step-by-step explanation:

The complementary angles complete each other to 90 degrees

if one of the angle is 1.7 degree then the other one is :

90 - 1.7 = 88.3 degrees

The second one

Step-by-step explanation:

Distance between (5,-3) and (9,1)=√(9-5)^2+(1-(-3))^2

=√4^2+4^2

=√16+16

=√32 units

It's not possible to calculate the distance between these points by pythagoras theorem .We can easily calculate it by distance formula I.e.√(x2-x1)^2+(y2-y2)^2

Step-by-step explanation:

Answer:

since 4/17 is smaller than 1, multiplying 4/17 with a. fraction smaller than 1 will yield a number still smaller than 4/17. This will still be smaller than 4/16. Hence the correct answer is A.

Step-by-step explanation:

Answer:

z = 4.5

Step-by-step explanation:

∠B = ∠B      ∠BAD = 90° - ∠B = ∠C

ΔBAD ~ ΔBCA

AB / z = BD / AB

z = AB * AB / BD = 3*3 / 2 = 4.5

I am of the belief this is the right answer according to the arithmetic calculator.

Answer:

A. 44/625

Step-by-step explanation:

There are 25 marbles total. To first calculate the probability of picking a yellow marble first can be represented as 11/25, the probability of picking blue is 4/25. We multiply these to figure out the probability of finding a yellow marble and then a blue one.

11/25 x 4/25 = 44/625

Answer:

6

Step-by-step explanation:

all you have to do is divide 54 by 9 because area is length times width

Answer:

6

Step-by-step explanation:

Area of a rectangle: l x b (Length x Breadth)

Note: Breadth is the same as width

Area = 54

Length = 9

Breadth = 54/9

             = 6

Hope this helped!!!! :))

Answer:

y = 3x + 1

Step-by-step explanation:

substitute the variables in y=mx+b

(5) = 3(-2) + b

5 = -6 + b

add 6 on each side

1 = b

They are wording it tricky, but it is simple. So first if you combine all the balls together there are 7, and 3 blacks ball 3/7.

Answer:

I believe you have the correct answer

Step-by-step explanation:

The probability of drawing a black marble from bag 1 is 2/3.

The probability of drawing a black marble from bag 2 is 1/4.

Since it is consecutive draws, we would multiply the 2 odds.

2/3 * 1/4 = 1/6

Answer:

[tex]\frac{3}{8}[/tex]

Step-by-step explanation:

After Saturday, there was [tex]\frac{5}{8}[/tex] of the journey left. [tex]\frac{3}{5}[/tex] of that would be:

[tex]\frac{5}{8}[/tex] *  [tex]\frac{3}{5}[/tex] = [tex]\frac{15}{40}[/tex] = [tex]\frac{3}{8}[/tex] of the journey.

Thus, the answer is 3/8

Answer:

1/216

Step-by-step explanation:

Hi, the probability of rolling it once is 1/6, twice in a row results in multiplying 1/6 by 1/6.

Therefore, three times means using the formula: (1/6)^3

Which gives us the fraction 1/216

Hope this helps, please give brainliest

Given:

A diagram of a composite figure.

Radius of cone and hemisphere is 8 cm.

Height of the cone is 15 cm.

To find:

The volume and the surface area of the composite figure.

Solution:

Volume of a cone is:

[tex]V_1=\dfrac{1}{3}\pi r^2h[/tex]

Where, r is the radius and h is the height of the cone.

Putting [tex]r=8,h=15[/tex] in the above formula, we get

[tex]V_1=\dfrac{1}{3}\pi (8)^2(15)[/tex]

[tex]V_1=\pi (64)(5)[/tex]

[tex]V_1=320\pi[/tex]

Volume of the hemisphere is:

[tex]V_2=\dfrac{2}{3}\pi r^3[/tex]

Where, r is the radius.

Putting [tex]r=8[/tex], we get

[tex]V_2=\dfrac{2}{3}\pi (8)^3[/tex]

[tex]V_2=\dfrac{1024}{3}\pi [/tex]

[tex]V_2\approx 341.3\pi [/tex]

Now, the volume of the composite figure is:

[tex]V=V_1+V_2[/tex]

[tex]V=320\pi +341.3\pi[/tex]

[tex]V=661.3\pi[/tex]

The volume of the composite figure is 661.3π cm³.

The curved surface area of a cone is:

[tex]A_1=\pi r\sqrt{h^2+r^2}[/tex]

Where, r is the radius and h is the height of the cone.

Putting [tex]r=8,h=15[/tex] in the above formula, we get

[tex]A_1=\pi (8)\sqrt{(15)^2+(8)^2}[/tex]

[tex]A_1=\pi (8)\sqrt{289}[/tex]

[tex]A_1=\pi (8)(17)[/tex]

[tex]A_1=136 \pi [/tex]

The curved surface area of the hemisphere is:

[tex]A_2=2\pi r^2[/tex]

Where, r is the radius.

Putting [tex]r=8[/tex], we get

[tex]A_2=2\pi (8)^2[/tex]

[tex]A_2=2\pi (64)[/tex]

[tex]A_2=128\pi [/tex]

Total surface area of the composite figure is:

[tex]A=A_1+A_2[/tex]

[tex]A=136\pi +128\pi[/tex]

[tex]A=264\pi[/tex]

The total surface area of the composite figure is 264π cm².

Therefore, the correct option is A.
