What is the slope of a line perpendicular to ta line whose equation is y = -3/4x - 6

Answer:

The surface area A of a sphere:

A=4πr^2

r - the radius

r=30 m

A=4π×30 ^2 =4π×900=3600π [m ^2 ]

Surface area = 3600π [m ^2 ]

Answer:

9 : D bc there are 6 cubes / squares then times tht by 3.3 cuz ur doin area.

8 : A

Answer: try 90 or 120

Step-by-step explanation:

becouse i did good maths in my head its to small to be 180 and to big to be 80 so e

Answer:

It is 7 sided

we know

3 sided- 180

4sided-360°

5 sided- 540°

.

.

7 sided- 900

here we can observe with an addition of a side, it results in addition of 180°

Step-by-step explanation:

so, 145+133+140+117+119+125+x = 900

x = 121

hope it helped

Answer:

A. 90 degrees

Step-by-step explanation:

a triangle has a total of 180 degrees in all of its angles combined (excluding the outside angles).

61+29=90

180-90=90

Answer:

P=75.922 ≈ 76

∘Step-by-step explanation:

What function uses the ADJACENT and the HYPOTENUSE?

SOH-CAH-TOA

cos P = adjacent/hypotenuse= 1.8/7.4

Pcos^-1 = (1.8/ 7.4)

​

P=75.922 ≈ 76

Answer:

Tank which is capable of holding 1 can fill each one of the tanks an exact number of time.

Step-by-step explanation:

Three tanks are capable of holding [tex]361,841,901[/tex]

To find which tank can be used to fill each one of them an exact number of time, find [tex]HCF(361,841,901)[/tex]

[tex]361=19^2\\841=29^2\\901=17(53)[/tex]

Therefore,

[tex]HCF(361,841,901)=1[/tex]

So, tank which is capable of holding 1 can fill each one of the tanks an exact number of time.

Answer:

By definition, atoms have no overall electrical charge. That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons.

Answer:

$15.62 is the tip and $90.37 total

Answer:

Stefan spent $120 originally

He made $24 dollars by selling the bicycle and helmet to Jin

Step-by-step explanation:

First, find the total cost:

127 + 17

= 144

To find the original cost, divide this by 1.2

144/1.2

= 120

So, Stefan spent $120 originally.

Now, find how much he made by subtracting 120 from 144:

144 - 120

= 24

So, he made $24 dollars by selling the bicycle and helmet to Jin.

Answer:

Plane

Step-by-step explanation:

The definition of a Plane is "In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far."

It couldn't be a Ray or a Line Segment because a Ray has 1 end point, and a Line Segment has 2.

It also couldn't be a Line because a Line is only 1 dimensional.

The answer has to be Plane.

Answer:

-16/65

Step-by-step explanation:

Given sinα = 3/5 in quadrant 1;

Since  sinα = opp/hyp

opp = 3

hyp = 5

adj^2 = hyp^2 - opp^2

adj^2 = 5^2 = 3^2

adj^2 = 25-9

adj^2 = 16

adj = 4

Since all the trig identity are positive in Quadrant 1, hence;

cosα = adj/hyp = 4/5

Similarly, if tanβ = 5/12 in Quadrant III,

According to trig identity

tan theta = opp/adj

opp = 5

adj = 12

hyp^2 = opp^2+adj^2

hyp^2 = 5^2+12^2

hyp^2 = 25+144

hyp^2 = 169

hyp = 13

Since only tan is positive in Quadrant III, then;

sinβ = -5/13

cosβ = -12/13

Get the required expression;

sin(α - β) = sinαcosβ - cosαsinβ

Substitute the given values

sin(α - β) = 3/5(-12/13) - 4/5(-5/13)

sin(α - β)= -36/65 + 20/65

sin(α - β) = -16/65

Hence the value of sin(α - β) is -16/65

Answer:

I think it may be 120 cm

Step-by-step explanation:

A F is 13 using pythagorean theorem on triangle CED and applying the hypotenuse length to A F.

ABC is similar to triangle CED and is dilated by a factor of 3  so the base is 36.

using pythagorean theorem on triangle ABC gets the hypotenuse length of 39 which can be applied to FE

add all the values together

39 + 13 + 15 + 36 +12 +5 = 120

Answer: $52.50

Step-by-step explanation:

There is $50 in the account and it earns interest at a rate of 5% a year.

This interest is not compounded therefore it is simple interest.

To calculate amount earned with simple interest is:

= Deposit * ( 1 + rate * time)

= 50 * ( 1 + 5% * 1 year)

= $52.50

Answer:

She made 32 free throw shots.

Step-by-step explanation:

Based on the given information, one can form the general equation;

[tex]\frac{made}{missed}[/tex]

Substitute in the given values;

[tex]\frac{4}{3}[/tex]

Assuming that the rates at which this proportion exists is constant, and one knows the number she missed, but not the number she made then one can say;

[tex]\frac{made}{missed}= \frac{4}{3} = \frac{made}{24}[/tex]

Solve the proportion using cross products;

[tex]\frac{4}{3}=\frac{made}{24}\\\\\\(4)(24)=(3)(made)\\\\96=3made[/tex]

Inverse operations,

[tex]96=3made\\/3\\\\32=made[/tex]
