if a men's shirt cost R299 now and R450 before the sale with what percentage did the price of the shirt decrease​

Answer:

b = 33.9925 whatever unit is required

Step-by-step explanation:

Sides:

a = 66 m

b = 33.9925 m

c = 56.573 m

Angles:

A = 90 °

B = 31 °

C = 59 °

Other:

P = 156.566 m

s = 78.2828 m

K = 961.53 m2

r = 12.2828 m

R = 33 m

Agenda:

C = angle C

a = side a

b = side b

c = side c

P = perimeter

s = semi-perimeter

K = area

r = radius of inscribed circle

R = radius of circumscribed circle

Formula: AAS is Angle, Angle, Side

Given the size of 2 angles and 1 side opposite one of the given angles, you can calculate the sizes of the remaining 1 angle and 2 sides.

Use the Sum of Angles Rule to find the other angle, then

use The Law of Sines to solve for each of the other two sides.

Answer:

60

Step-by-step explanation:

100% of the num is 40

150%=1.5

So multiply 40 by 1.5

=60

Other way (confusing)

50x3=150

20x3=60

The required 150% of the number is 60.

Given that,
Kai knows that 50% of a number is 20, how could he use the information to determine what 150% of the number is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

the percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Let the number be x,
It's 50 % is 20. i.e.
50% of  x = 20
50 / 100 * x = 20
x / 2 = 20    (50 / 100 = 1 / 2)
x = 40

Now its 150%
= 150% of 40
= 150 / 100 * 40
= 15 / 10 * 40
= 15 * 4
= 60

Thus, the required 150% of the number is 60.

Answer: P=5.2 h=3 B=2

Step-by-step explanation:

To find P, you add everything except for 3 because P starts for perimeter of the bases and 3 is the height of the prism. So P would equal 5.2. Then to get h, it’s just 3 because that’s the height of the prism. Now for B, you just multiply 1x2 because that’s the area of the base and you only need one. If you’re looking for total surface area, the answer is 19.6 becasue the formula is Pxh+2B meaning perimeter x height plus 2 x B. But for lateral, the answer is 15.6 because it’s just Pxh (perimeter x height) hope this helps lol sorry it’s so long.

Answer:

1) (the red) y= 3x +2

2) (the green) y= -1x + 4

Step-by-step explanation:

Slope intercept form: y = mx + b

where m is the slope and b is the y intercept.

you can find the slope by using the formula [tex]\frac{rise}{run}[/tex], where you use two points on the line and find the space between the two.

Pic 1 or has line that is orange

y=3x+2

Pic 2 or has line that is green

y=-1x+4

Slope intercept form is y=mx+b.

m=slope

b=y-intercept

For pic 1, the point which is intercepted at the y-axis is 2, so the y-intercept is 2.

To find the slope, we take two points, I'm using (-1,-1) and (-2,-4) and divide y2-y1 and x2-x1.

-4-(-1)  /  -2-(-1)

= -3/-1 = 3

b= 2

m= 3

y=3x+2

For pic 2, the point that is intercepted at the y-axis is (0,4), so the y-intercept is 4.

To find the slope, we take the two points (-2,6) and (-1,5) and divide.

5-6 / -1-(-2)

= -1/1 = -1

b= 4

m= -1

y=-1x+4

Answer:

x=55  (i think)

Step-by-step explanation:

Answer:

129 degrees

Step-by-step explanation:

Ok, DAE, as given, is 90 degrees. So, BAD would equal 90 as well, so BAC would be 90-51, 39. And because FAE is vertical angle to BAC, FAE is also 39. So 39 + 90 is 129.

The total fabric Morgan needs to cover the cushions will be 19.64 square feet.

It is given that each cushion has a circumference of 7.85 feet.

It is known that the circumference of a circle = 2πr, where 'r' is the radius of the circle.

2πr = 7.85

r = 1.25

area of a circle is πr².

now, we can calculate the area = π× 1.25² = 4.91 square feet

since each circular cushion has two circular faces so the total number of faces Morgan needs to cover will be 4.

Therefore, the total fabric needed= 4×4.91 = 19.64 square feet.

The height of the boat floating above the seafloor at high tide is 17.5 feet

The ratio of the similar sides of the triangles is equal to a constant. In order to determine how high the boat is, we will use the ratio below;

20/40 =x/35

Determine the value of x

40x = 20 * 35
40x =700

x = 700/40
x = 17.5feet

Hence the height of the boat floating above the seafloor at high tide is 17.5 feet

Answer:

$0.346 each

Step-by-step explanation:

To find the unit price of each notebook you would divide 3.46 by 10 ending up with 0.346

Using the probability concept, it is found that an employee is more likely to choose swimming, with a 0.4236 = 42.36% probability, compared to a 0.3073 = 30.73% probability for playing games.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

For playing games, the probability is:

p = 169/550 = 0.3073.

For swimming, the probability is:

p = 233/550 = 0.4236.

Hence, an employee is more likely to choose swimming, with a 0.4236 = 42.36% probability, compared to a 0.3073 = 30.73% probability for playing games.

Answer:

feets of green fabric - 2feets = answer

Step-by-step explanation:

the inch of the total fabric wasn't given but the path given was that given to her sister

being 24inch

we are supposed to turn the inch to feet to find the answer

so, if

1 inch = 1 feets

12

therefore,

24inch = 1\12 * 24 = 2

let total feet of the fabric = f and

let part left of the fabric = p

therefore, p = f - 2

where p = part left

f = total fabric

Answer:

Step-by-step explanation:

g is a central angle for arc PQ

= 2 * segment angle of arc PQ

= 2 * <PRQ

= 2 * (180 - 114)

= 2 * 66

= 132 degree

Drawing is a little confusing about f and assuming f is <PQO

<PQO = <QPO because OPQ is an isosceles triangle

The sum of interior angles of a triangle = 180 degree

f + f + g = 180

2f = 180 - 132 = 48

f = 24 degree

Edit: Thank you, fieryanswererft, for pointing out my mistake!

Answer:

g = 132° , f = 24°

Step-by-step explanation:

∠ PRQ = 180° - 114° = 66°

the central angle g is twice the angle subtended at the circumference on the same arc PQ , then

g = 2 × ∠ PRQ = 2 × 66 = 132°

Δ POQ is isosceles , 2 congruent sides , the radii OP and OQ

The base angles of the triangle are congruent , then

f = [tex]\frac{180-132}{2}[/tex] = [tex]\frac{48}{2}[/tex] = 24°
