Answer:

22cm²

Step-by-step explanation:

For the area of triangle,

base = 2 + 2 + 2 = 6cm

height = 4cm

Area = 1/2 x base x height

= 1/2 x 6 x 4

= 12cm²

For area of the rectangle,

length = 5cm

breadth = 2cm

Area = length x breadth

= 5 x 2

= 10cm²

Area of compound shape = 12 + 10 = 22 cm²

Answer:

67

Step-by-step explanation:

Number: AB

A = B-1

BA + AB = 143

10*B + A + 10*A + B = 143

11A + 11B = 143

A + B = 13

(B-1) + B = 13

2B = 14

B = 7

A = 6

The number is 67

check: 6 = 7-1   and   67 + 76 = 143

Answer:

9/4 or 2 1/4 cups of sugar.

Step-by-step explanation:

To find the answer we multiply 3/4 by 3.  Because the bottom stays the same, we wont multiply it.  Since 3 x 3 = 9, it will be 9/4.  Therefore, 9/4 or 2 1/4 is your answer.

Explanation:

Given:

−3x2+12x+1=0

This is in the form:

ax2+bx+c=0

with a=−3, b=12 and c=1

In order to decide which method to use, we can first examine the discriminant:

Δ=b2−4ac=122−4(−3)(1)=144+12=156

Since Δ>0 we can tell that the quadratic has 2 distinct real solutions, but because it is not a perfect square we can also tell that those solutions are irrational.

So there is no rational factorisation and we can discount the use of an AC method or similar.

We can use the quadratic formula or we can complete the square.

If we choose to use the quadratic formula, then we find:

x=−b±√b2−4ac2a

x=−b±√Δ2a

x=−(12)±√1562(−3)

x=−12±2√39−6

x=2±√393

When completing the square, note that b=12 is already divisible by a=−3 and by

Step-by-step explanation:

The number of subsets of P simply refers to the power of the sets.

P(P) = 2^n(P)

where P(P) is the power of the set P

n(P) is the cardinality of set P

P(P) = 2^2 = 4

Volume of the prism:

Scaled volume is 60 - 70 in³

Find the scale factor k;

So the scale factor is

and the volume of the smaller prism is:

Answer:

Scale factor 1/19, volume 65.6 in³

Step-by-step explanation:

Volume of the prism:

V = abh

V = 300*50*30 = 450000 in³

Scaled volume is 60 - 70 in³

Find the scale factor k;

450000/60 = 7500

450000/70 = 6428

1/6428 < 1/k³ < 1/7500

1/∛6428 < 1/∛k³ < 1/∛7500

1/18.59 < 1/k < 1/19.57

1/k = 19 is best

So the scale factor is

k = 1/19

and the volume of the smaller prism is:

450000 / 19³ = 65.6 in³

Answer:

we know all angles are 90° in the rectangle

therefore, angle d = bdc+bda = 90

=> 31+bda = 90

=>angle bda= 59

The measurement of the angle ADB should be considered as the 59 degrees.

Since we know that all angles in the rectangle should be of 90 degrees

So,

Here angle d = bdc + bda

= 90

Now

31 + bda = 90

So, bda = 90 - 31

= 59

hence, The measurement of the angle ADB should be considered as the 59 degrees.

Answer:

a. Sin θ = y/r

b. csc θ = r/y

c. cos θ = x/r

d. sec θ = r/x

e. tan θ = y/x

f. cot θ = x/y

g. x² + y² = 1

Step-by-step explanation:

Where (x, y) are the x and y coordinates of the position with radius r and angle θ measured from the positive x axis. y is the opposite side to the angle θ and x is the adjacent side to the angle θ and r is the hypotenuse side of the right-angled triangle formed by x, y and r. Also, x² + y² = r²

a. Sin θ = opposite/hypotenuse = y/r

b. csc θ = hyotenuse/opposite = 1/Sin θ = r/y

c. cos θ = adjacent/hypotenuse = x/r

d. sec θ = hypotenuse/adjacent = 1/cos θ = r/x

e. tan θ = opposite/adjacent = y/x

f. cot θ = adjacent/opposite = 1/tan θ = x/y

g. Equation of the Circle: _ the unit circle (r = 1),

Since x² + y² = r² ,for a unit circle, r = 1. So,

x² + y² = 1²

x² + y² = 1
