Step-by-step explanation:

Answer:

The center is located at (-1, -2), and the radius is 5.

Step-by-step explanation:

The general equation of a circle is given as

(x - a)^2 + (y - b)^2 = r^2

where

a and b are the centre of the circle and r is the radius

Given the equation

x2 + 2x + y2 + 4y = 20

add 1 ad 4 to both sides

x2 + 2x + 1 + y2 + 4y + 4 = 20 + 4 + 1

factorise

(x +1)^2 + (y+2)^2 = 5^2

comparing with the general equation

a = -1, b = -2, r = 5 (all measured in units)

Answer: The center is located at (-1, -2), and the radius is 5.

Answer:

27 tiles

Step-by-step explanation:

First, find the total area of the kitchen.

Use the area formula, A = lw

A = lw

A = (9)(12)

A = 108

So, the area of the kitchen is 108 sq ft

Find the area of the square tiles, using the same formula:

A = lw

A = (2)(2)

A = 4

So, the area of one square tile is 4 sq ft

Find how many tiles they will need to buy by dividing the total area by the area of one tile:

108/4

= 27

So, they will need to buy 27 tiles

Answer:

To find the total area of the kitchen.

area formula, A = lw

A = lw

A = (9)(12)

A = 108

So, the area of the kitchen is 108 sqft

To find the area of the square tiles

A = lw

A = (2)(2)

A = 4

So, the area of one square tile is 4 sqft

Find how many tiles they will need to buy by dividing the total area by the area of one tile:

108/4

= 27

So, Tiles Needed= 27

Answer:

Step-by-step explanation:

Amy is running 1 mile every 15 minutes, so 15*7 will give you your answer, which is 105. Divide 105 by 60 to convert into hours, which is 1 hour and 15 mins.

Answer:

1.75 hours

1 hour and 45 minutes

Step-by-step explanation:

[tex]\frac{7}{y}: \frac{2}{30}[/tex]

y · 2 = 30 · 7

2y = 210

2y ÷ 2 = 210 ÷ 2

y = 105

1 hour = 60 minutes

y hours = 105 minutes

[tex]\frac{1}{60}: \frac{y}{105}[/tex]

y · 60 = 105 · 1

60y = 105

60y ÷ 60 = 105 ÷ 60

y = 1.75

Answer:

7.25

Step-by-step explanation:

In the question, the term at least means less than or equal to is represented by ≥

Let the cost of each gift = c

He is buying gifts for 8 friends = 8 gifts

Hence, our Inequality equation is written as:

(c + $1.50)× 8 ≥ $70

8c + 12 ≥ 70

8c ≥70 - 12

c ≥ 58/8

c≥ 7.25

Therefore, the amount Claudio needs to spend on each gift in order to receive free shipping is 7.25

Answer:

x = 10

Step-by-step explanation:

Since you said don't explain, I'll show minimal work:

ΔABC and ΔADE are similar (Thales Intercept Th.)

Proportion:

[tex]\frac{AB}{AD} = \frac{BC}{DE}[/tex]

[tex]\frac{x}{x + 10} =\frac{8}{16}[/tex]

[tex]8x + 80 = 16x[/tex]

[tex]8x = 80[/tex]

[tex]x = 10[/tex]

Answer:

60

Step-by-step explanation:

if you look at it close the top shape is half of 12 so its 6 so nosubtract 6 from 18 and get 12 now add (18+12+6+6+12+6=60)

Answer:

a. x =145

b. a = 75 c=75 b= 105

c. y= 115

d. z = 105

Step-by-step explanation:

a. half a circle equals 180 degrees, subtract 35 from 180 gives u the answer

b. full circle equals 360 degrees, angle 105 is congruent to b meaning b is also 105. Leaving us with 150 degrees, divide 150 by 2 giving 75 to both a and c.

c. add 160 and 85 gives us 245 then subtract that from 360 giving us 115.

d. again half a circle equals 180. subtract 75 from 180 gives us 105

Answer:

Hello!

a: x = 145

b: b = 105 c = 75 a = 75

c: y = 115

d: z = 105 not to sure for question d so put that at your own risk everything else im sure about

Answer: 5

Step-by-step explanation: y=f(x)=3

y=f-2=3

y=f=3+2

y=f=5

f=5

Answer:

y = 3x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 2 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes , then

y = 3x + c ← is the partial equation

To find c substitute (3, 8 ) into the partial equation

8 = 9 + c ⇒ c = 8 - 9 = - 1

y = 3x - 1 ← equation of parallel line

Have a great day and stay safe !

Answer:

one

Step-by-step explanation:

althought the lines look parallel the

slope on the blue line is 1

slope on the red line is 3.5

therefor there is one solution

=============================================================

Explanation:

BC = 78 is parallel to the midsegment DE.

This parallel midsegment is half as long as BC, so DE = BC/2 = 78/2 = 39

-------

DF = 34 doubles to AB = 2*DF = 2*34 = 68, since the midsegment is half as the parallel side, so we just think in reverse of that process.

-------

BE = 34 for two reasons

--------

We don't use the info that AC = 48.

Answer:

20...90°-46°

=44°

therefore 44÷4

=11

therefore x=11

21....90°-20°

=70°

Step-by-step explanation:

Line Plot is a graph that presents data through number line. Here, possible values of considered variable are on number line, & their frequency is denoted by number of dots or crosses above.

As per given line plot for pencils height : pencil height 3 with 3 students, pencil height 4 with 5 students , pencil height 5 with 3 students

So, students having pencil height < 4, ie = 3 & 4 , are 3 + 5 [ total 8 ] students]

Answer:

Option D

Step-by-step explanation:

Vertices of the polygon are A(1, 3), B(7, 3), C(7, 7), D(4, 7)

Measure of AB = 7 - 1 = 6 units

Measure of BC = 7 - 3 = 4 units

Measure of CD = 7 - 4 = 3 units

From the figure attached,

Area of the trapezoid = [tex]\frac{1}{2}(AB+CD)(BC)[/tex] [Here, AB and CD are the parallel bases and BC is the height of the trapezoid]

                                    = [tex]\frac{1}{2}(6+3)(4)[/tex]

                                    = 18 square units

Therefore, Option D will be the correct option.
