Find the missing angle in this triangle

Answer:

a=12 b=9

Step-by-step explanation:

u can substitute 3/4a in for b in a+b=12 since it is equal to b, giving you

a+3/4a=21

a=4/4a

4/4a+3/4a=21

7/4a=21

4/7(7/4a=21)

a=12

plug in 12 for a in either equation

b=3/4*12

b=9

(21=12+b) -12

9=b

Answer:

A series can be represented in a compact form, called summation or sigma notation. The Greek capital letter, ∑ , is used to represent the sum. The series 4+8+12+16+20+24 can be expressed as 6∑n=14n . The expression is read as the sum of 4n as n goes from 1 to 6 .

Answer:

280 square units

Step-by-step explanation:

Area of the rectangle:

  A = b* h = 16 * 15 = 240

Area of the triangle:

   A = bh/2 = (16*5)/2 = 40

Total area = area of triangle + area of rectangle = 240 + 40 = 280 square untis.

Answer:

5/13

Step-by-step explanation:

We can first start by finding the number of even numbers in one suit and then multiply by 4. The even numbers are:

2, 4, 6, 8, 10

There are 5, and since there are 4 suits, there is a total of 20 even cards.

Probability is equal to the amount of desirable outcomes over the total number of outcomes. The desirable outcomes are when we pull out an even number, and as we calculated earlier, there are 20 of those. There are 52 total cards, so that is the number of total outcomes. We get the expression:

20 / 52 which simplifies to 5/13

Answer: 68 cubic inches

Step-by-step explanation:

basically the volume of the rectangular prism would be 2 x 2 x 14, so that's 56. Then the area of the triangular prism is 3 x 2 x 2, divided by 2, which is 6. There are two triangular prisms so that' 12. 56 + 12 is 68. That's the answer

Answer:

Down below

Step-by-step explanation:

The area of the provided geometry will be 84 square feet. Then the cost of the fertilizer will be $ 5.04.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The diagram shows the dimensions of Mr. Green’s garden.

A figure can be broken into 3 rectangles.

One rectangle has a base of 8 feet and a height of 3 feet.

Another has a base of 11 feet and a height of 4 feet.

Another has a base of 8 feet and a height of 2 feet.

Then the area of the figure will be

Area = 8 x 9 + 4 x 3

Area = 72 + 12

Area = 84

A bag of fertilizer costs $3 and covers an area of about 50 square feet.

The cost for Mr. Green to fertilize his garden will be

Cost = 3/50 x 84

Cost = $ 5.04

Question :

How high above the ground is the eagle?

Answer:

91.9 m

Step-by-step explanation:

From the diagram :

We can obtain h, using the trigonometric relation :

Tanθ = opposite / Adjacent

Opposite = h

Adjacent = 116

Tan 38° = h / 116

0.7812856 = h / 116

h = 0.7812856 * 116

h = 90.629132

Eagle's height above the ground :

h + 1.3m

h = 90.629132m

Height above the ground = 90.629132 + 1.3 = 91.9 m above the ground.

In bottle 1/4 of chlorine solution is left in bottle.

What is an expression?

Expression in math is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that;

Felicia pours 3/4 of a 2 1/2-liter bottle of chlorine solution into a swimming pool.

And, then she measures out 3/8 liters of the remaining solution to use to clean the pool filter.

Now,

Chlorine solution in bottle = 2 1/2 × ( 1 - 3/4 ) - 3/8

                                        = 5 / 2 × 1/4 - 3/8

                                        = 5 / 8 - 2 / 8

                                        = 1 / 4

Thus, In bottle 1/4 of chlorine solution is left in bottle.

Answer: Length = 10cm

Width = 6.5cm

Step-by-step explanation:

Let the width of the rectangle be represented by x.

Therefore, the length of the rectangle will be: = (2 × x) - 3 = 2x - 3

Therefore area of a rectangle = length × width

x(2x - 3) = 65

2x² - 3x = 65

2x² - 3x - 65 = 0

2x² + 10x - 13x - 65 = 0

2x(x + 5) - 13(x + 5) = 0

(2x - 13)(x + 5) = 0

2x - 13 = 0

2x = 13

x = 13/2

x = 6.5

Width = 6.5cm

Length = 2x - 3

= 2(6.5) - 3

= 13 - 3

= 10cm

Therefore, the length of the rectangle is 10cm and the width is 6.5cm.

Answer: 96 oscillations

Step-by-step explanation:

The fan oscillates at a rate of 12 times per minute.

This means that for every minute that goes by, the fan would have oscillated 12 times.

If the fan is on for 8 minutes, the number of oscillations is:

= Oscillations per minute * number of minutes

= 12 * 8

= 96 oscillations
