Answer:

w = -19

Step-by-step explanation:

10 + w = -9

-10         -10

w = -9 - 10

w = -19

Answer:

13 (i think)

Step-by-step explanation:

Answer:

P = 17

Step-by-step explanation:

3y – 2 = y + 4

3y -2 (+2) = y + 4 (+2)

3y = y + 6

3y (-y) = y (-y) + 6

2y = 6

2y / 2 = 6 / 2

Y = 3

PR = 3y – 2

PR = 3(3) – 2

PR = 9 – 2

PR = 7

P of PQR = 4 + 6 + 7

P of PQR = 17

Answer:

4.51°

Step-by-step explanation:

1 mile= 5280 feet

6 mile= 6(5280) =31680 feet

Angle of elevation is 0 where

tan 0 = 2500/ 31680 = 0.0789

Hence 0 = tan-1(0.0789) = 4.51°

hope it helps!

The answer is below

Step-by-step explanation:

Distance between two points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)\ on \ the\ coordinate\ plane[/tex]

[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The area of rectangle = length * breadth

The area of rectangle ABCD = |AB| * |BC|

[tex]|AB|=\sqrt{(6-0)^2+(4-4)^2}=6\\\\|BC|=\sqrt{(6-6)^2+(0-4)^2} =4[/tex]

The area of rectangle ABCD = |AB| * |BC| = 6 * 4 = 24

E(x, y) is midpoint of line DC. Its coordinate is:

x = (6 + 0) / 2 = 3; y = (0 + 0) / 2 =0

The coordinate of E = (3, 0)

F(a, b) is midpoint of line DA. Its coordinate is:

a = (0 + 0) / 2 = 0; b = (4 + 0) / 2 = 2

The coordinate of E = (0, 2)

The area of rectangle DEGF = |DE| * |DF|

[tex]|DE|=\sqrt{(3-0)^2+(0-0)^2}=3\\\\|DF|=\sqrt{(0-0)^2+(2-0)^2} =2[/tex]

The area of rectangle ABCD = |DE| * |DF| = 3 * 2 = 6

Therefore, area of rectangle DEGF is one fourth the area of rectangle ABCD

Answer:

b / (b - 8)

Step-by-step explanation:

Given that :

Litres of water held by bucket = b

Jar holds 8 litres fewer than bucket; hence, litres held by jar = b - 8

The number of times bucket can hold than jar is :

Litres held by bucket / litres held by jar

b / (b - 8)

Answer:

Mean height of 159

Step-by-step explanation:

Add 153 and 165, then divide by 2 to find the average of 159.

Answer:12.4 inch

Step-by-step explanation:

49.4 is the total length of the rope. And you have to equally divide it into 4 parts.

So 49.4/4

=12.4 inch(rounded off to 3 s.f from 12.35)

Answer:

Compounded Quarterly

Step-by-step explanation:

This is because the compound interest equation is dependent on the number of times the amount is compounded per year. Monthly is 12 times per year and quarterly is only 4. Simple interest stays at a linear rate.

Step-by-step explanation:

[tex]x = \frac{7}{ \sqrt{3} } = \frac{7 \sqrt{3} }{ \sqrt{3 } \times \sqrt{3} } = \frac{7 \sqrt{3} }{3} [/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

Q1)

Use Phythogoras theorem:

[tex](AC)^2=(BC)^2+(AB)^2\\BC^2=AC^2-AB^2\\BC^2=6^2-4^2\\BC^2=36-16\\BC^2=20\\\\Apply\ square\ on\ both\ sides\\\\\sqrt{BC^2}=\sqrt{20} \\BC=\sqrt{20} \\BC=\sqrt{10(2)} \\BC=\sqrt{5(2)(2)} \\BC=2\sqrt{5}[/tex]

Q2)

Apply phythogoras theorem:

[tex]CD^2=CE^2+DE^2\\CD^2=7^2+9^2\\CD^2=49+81\\CD^2=130\\\\Apply\ square\ root\ on\ both\ sides\\\\\\sqrt{CD^2} = \sqrt{130} \\\\CD=\sqrt{130} \\\\CD=11.4[/tex]

Q3)

Apply phythogoras theorem again:

[tex]BC^2=BD^2+CD^2\\BC^2=7^2+13^2\\BC^2=49+169\\BC^2=218\\\\Apply\ square\ root\ on\ both\ sides\\\\\\sqrt{BC^2} =\sqrt{218} \\\\BC=\sqrt{218} \\\\BC=14.76[/tex]

Step-by-step explanation:

Of the raise to power

Step-by-step explanation:

21/20 = m/100

m = 100 * (21/20) = 105.

Answer:

1. 24 + x

2. 7v - 14

3. 3v - 27

Step-by-step explanation:

Distributive property means that you go through something by either multiplying or dividing by whatever may be in the parentheses.

1. For one you would multiply the 3 through. 3 x 8 + 3x which can be simplified into 24 + 3x.

2. For two you would multiply the 7 through. 7v - 7 x 2, which can be simplified into 7v - 14.

3. For three you would multiply the 3 through. 3v - 3 x 9, which can be simplified into 3v - 27

Hope this helps!

Please tell me if I am incorrect I enjoy learning from my mistakes!

Good luck!

By simple addition we can reduce the no. Of steps involved.

Answer:

Subtracting; x = 3/2, y = 8

Step-by-step explanation:

1. Subtracting them from one another because the 1/2y term matches up.

2. when added together:

8x = 12

x = 3/2

plug the x value into one of the equations:

y = 8

Answer:

X + 31 =(2x-8)

first remove the brackets

X+31=2x-8

(x-x)+31=2x-x-8

31 = x-8

31-8= -8-8+x

23=x

exterior angle

2x-8

(23+23)-8

46-8

exterior angle =38

Answer:

Find the Equation of a Line Given That You Know Two Points it Passes Through. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.

Step-by-step explanation:

Answer:

196 m² ; 1000 m

Step-by-step explanation:

Given that:

Dimension of rectangular garden = 60m by 40m

Width of the 2 paths that run across each other = 2m

Hence,

Area of path 1 = (length * width) = (60 * 2) = 120m²

Area of path 2 = (breath * width) = (40 * 2) = 80m²

Area of Point where both paths cross each other (2 * 2) = 4m²

Total area covered by both path = (120m² + 80m² - 4m²) = 196m²

B.)

Area of rectangular field = 60000m²

Ratio of length and breadth = 3 : 2

Length * breadth = 60000

x ; breadth = (2/3)x

x * (2/3)x = 60000

2/3 x² = 60000

x² = 60000 ÷ 2/3

x² = 40,000

x = sqrt(40000)

x = 200

(3/2) * 200 = 300

Length = 300

Hence,

Perimeter = 2(length + breadth)

Perimeter = 2(300 + 200)

Perimeter = 2(500)

Perimeter = 1000m

7^2=49

40+49+10

40+49=89+10=99

99

Answer:

99

Step-by-step explanation:

According to PEMDAS, solve for the parenthesis first:
