Answer:

Equation 1 a=-8/3

Equation 2 b= -3

Step-by-step explanation:

Equation 1

5a+5=2a-3

5a-2a=-3-5

3a=-8

a=-8/3

Equation 2

-2b=16-10

-2b=6

b=6/-2

b=-3

Answer:

180

Step-by-step explanation:

so if it is addition like I assume it is, you would do this:

18 +18 +18 +18 +18 +18 +18 +18 +18 +18

that is also equal to 18x10.

so 18 ten times. a simple trick for multiplying by ten is just adding a zero, so 18x10 is 180.

I THINK THIS IS RIGHT LOL

Hey there!

18 * 10

≈ 18 + 18 + 18 + 18 + 18 + 18 + 18 + 18 + 18 + 18

≈ 36 + 36 + 36 + 36 + 36

≈ 72 + 72 + 36

≈ 144 + 36

≈ 180

Therefore, the answer should be: 180

Good luck on your assignment & enjoy your day!

Answer:

x = 8, y = 8

Step-by-step explanation:

So we know angle CAB is congruent to angle ACB so both angles are 69.

Now we add 69+69 and we get 138. Subtract from 180.

180 - 138 = 42.

Now, we set up the equation to 5x+2=42,

subtract two from both sides and get 5x = 40,

divide both sides by 5 and you get x=8.

You can simply plug in x to 5 and add two and still get 42.

Answer:

A. 36 cm

Step-by-step explanation:

Perimeter = SQ + RS + RQ

✔️Find SQ:

SN = SM = 10 cm (tangents drawn from an external point)

QL = QN = 2 cm (tangents drawn from an external point)

SQ = SN + NQ

SQ = 10 + 2 = 12 cm

✔️Find RS:

RS = RM + MS

RM = RL = 8 - 2 = 6 cm

MS = 10 cm (given)

Therefore,

RS = 6 + 10 = 16 cm

✔️RQ = 8 cm (given)

Thus:

Perimeter = SQ + RS + RQ

Perimeter = 12 + 16 + 8 = 36 cm

The rule which describes the composition of transformations is reflection around y axis and translation of (6, -5).

Transformation of geometrical figures or points is the manipulation of a given figure to some other way.

Different types of transformations are Rotation, Reflection, Glide reflection, Translation and Dilation.

Given triangle BCD has the coordinates equal to,

B(1, 4), C(1, 2) and D(5, 3).

Let the triangle be reflected around the Y axis.

A point (x, y) after the reflection over the Y axis changes to (-x, y).

The coordinate points are,

B'(-1, 4), C'(-1, 2) and D'(-5, 3).

Now let the triangle be translated to (6, -5).

The coordinates of the triangles are,

B''(-1+6, 4-5), C''(-1+6, 2-5) and D''(-5+6, 3-5)

B''(5, -1), C''(5, -3) and D''(1, -2).

This is the exact coordinates of triangle B''C''D''.

Hence the correct transformation is reflection around y axis and translation of (6, -5).

Answer:

(8 * 4) - 1/2(12 + 10 + 16)

Step-by-step explanation:

To determine the area of the triangle RST;

Draw a rectangle to enclose the triangle RST, after drawing the rectangle, 3 other triangles are formed. The sum of the areas of the 3 triangles formed is then subtracted from the area of the rectangle ;

The area of the rectangle depicts the entire area of the entire figure.

Area of rectangle = (length * width)

Area of triangle = 1/2 * base * height

Area of rectangle = (8 * 4)

Area of triangle 1 = 1/2 (3*4) = 1/2 * 12

Area of triangle 2 = 1/2 (2*5) = 1/2 * 10

Area of triangle 1 = 1/2 (2*8) = 1/2 * 16

Hence, Area of RST ;

Area of rectangle - (area of (triangle 1 + triangle 2 + triangle 3))

(8 * 4) - [(1/2 * 12) + (1/2 * 10) + (1/2 * 16)]

(8 * 4) - 1/2(12 + 10 + 16)

Answer:

0.95

Step-by-step explanation:

The computation of the probability that a customer neither buys beer nor buys cigars is given below;

Given that, the probabilities are

The customers who purchased cigars be 0.02

The customers who purchased cigars + beer 0.50

And, the customers who purchased beer + cigars be 0.25

Now the probabilities where the customer purchased both

= 0.05 × 0.02

= 0.10

The probability where the customer purchased beer is

= 0.01 ÷ 0.25

= 0.04

Now the probability where a customer neither buys beer nor buys cigars is

= 1 - 0.02 + 0.04 - 0.01

= 0.95

Answer:

6cm ; 22cm

Step-by-step explanation:

Given that:

Total Length, AD = 28cm

AB =x cm

BC = (x +5)cm

CD = 2x - 1 cm

4x + 4 = 28

4x = 28 - 4

4x = 24

x = 24 / 4

x = 6cm

The length of BD

BD = BC + CD

BD = (x + 5) + (2x - 1)

x = 6

BD = (6 + 5) + (2(6) - 1)

BD = 11 + (12 - 1)

BD = 11 + 11

BD = 22 cm

if each year it goes up by 5% and it's already been 3 yrs.

then 3 x 5 = 15%

now it's at 15 %

The recursively defined function that describes the given situation would be f(n) = f(n-1) x 0.9, after four years, 9185 birds will be remaining.

A function is defined as a relation between the set of inputs having exactly one output each.

The native bird population in a city is decreasing at a rate of 10% per year after 1 year the population of native birds is 14000.

f(0) = 14000

f(n) = f(n-1) x 0.9

f(1) = f(0) x 0.9

= 14000 x 0.9

= 12600

f(2) = f(1) x 0.9

= 12600 x 0.9

= 11340

f(3) = f(2) x 0.9

= 11340 x 0.9

= 10206

f(4) = f(3) x 0.9

= 10206 x 0.9

= 9185.4

Therefore, after four years, 9185 birds will be remaining.

Answer:

r=−5.3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−7.4r−6.31=3.23−5.6r

−7.4r+−6.31=3.23+−5.6r

−7.4r−6.31=−5.6r+3.23

Step 2: Add 5.6r to both sides.

−7.4r−6.31+5.6r=−5.6r+3.23+5.6r

−1.8r−6.31=3.23

Step 3: Add 6.31 to both sides.

−1.8r−6.31+6.31=3.23+6.31

−1.8r=9.54

Step 4: Divide both sides by -1.8.

−1.8r/−1.8=9.54/−1.8
