Answer:

11 Pounds

Step-by-step explanation:

Since it says "about how much" we can round 18.2 to 18 and 7.4 to 7 then we subtract 18-7=11

That means the answer would be 11 pounds.

Hope that helps and have a great day!

Answer:

Prob (Online search or Skip test drive) = 0.69

Step-by-step explanation:

Prob (Online search) = P(OS) = 65% = 0.65

Prob (Skip test drive) = P (STD)  11% = 0.11

Prob (Online search & Skip test drive) = P (OS ⋂ STD) =  7% = 0.07

Prob (Online search or Skip test drive) = P (OS U STD) :-

P(OS) + P (STD) -  P (OS ⋂ STD)  

= 0.65 + 0.11 - 0.07  

= 0.69

Answer:

$45

Step-by-step explanation:

4 lbs = $18

2 lbs = $9

10 lbs = $45

Answer:

If 4 pounds cost $18. you gotta find the cost of 1 pound

divide 18 by 4 = 4.5

and 4.5 times 10 is: 45

Step-by-step explanation:

$45 dollars for 10 pounds!

Answer:

f(x)=50x+100

a)rate of change is 50

b)y-intercept is 100

c)x represents the no. of weeks

f(x) represents the  the total cost for x weeks.

d)f(12)=700

e)Cost and week cannot be negative

Step-by-step explanation:

Sign up fee at daycare = $100

Cost of 1 week = 50

Cost of x weeks = 50 x

So, Total cost = 100+50x

Thus f(x)=50x+100

a)

General equation : y=mx+c

m = slope = rate of change

On comparison

m = 50

So, rate of change is 50

50 is the cost of daycare per week

b)

y intercept : y intercept is a point where a line 's graph intersects (crosses) the Y-axis i.e. x=0

Substitute x = 0 in equation

f(x)=50(0)+100

f(0)=100

So, y-intercept is 100

$100 is a signup fee

c)

x represents the no. of weeks

f(x) represents the  the total cost for x weeks.

d)

Substitute x = 12

So, Cost for a baby to attend daycare for 12 weeks:

f(12)=50(12)+100

f(12)=700

e)

f(-3)=50(-3)+100=-50

Here it is asking about negative 3 weeks which is not possible

Since no. of weeks cannot be negative

On solving we are getting the negative total cost

Cost and week cannot be negative

Answer:

m<3 = 66°

Step-by-step explanation:

<3 is an angle with its vertex inside the circle shown in the diagram. This, it's an internal angle.

The measure of an internal angle is equal to half the sum of the measure of the arcs intercepted.

Thus, the equation that shows relationship between <3 and arc WX and arc YZ is shown below:

m<3 = ½(40 + 92)

m<3 = ½(132)

m<3 = 66°

The measure of m<3 = 66°

Since  arc WX = 40' and arc Y Z = 92

So we know that

The measure of an internal angle should be equivalent to half the sum of the measure of the arcs intercepted.

So based on this

m<3 =0.50 (40 + 92)

m<3 = 0.50(132)

m<3 = 66°

hence, The measure of m<3 = 66°

[tex]\left[\begin{array}{ccc}-3&8&5\\-9&26&11\end{array}\right][/tex]

Step-by-step explanation:

Given the matrix A

[tex]\left[\begin{array}{ccc}-3&8&5\\-1&2&3\end{array}\right][/tex]

We are to find the matrix that results from the elementary row operations represented by −3R2+4R1

R2 means row 2

R1 means row 1

Applying the elementary row operation will change the second row of the matrices.

For the first column, second row (a₂₁)

If R1 = -3, R2 = -1

a₂₁ = -3R2+4R1

a₂₁ = -3(-1)+4(-3)

a₂₁ = 3-12

a₂₁ = -9

For a₂₂

If R1 = 8, R2 = 2

a₂₂ = -3R2+4R1

a₂₂ = -3(2)+4(8)

a₂₂ = -6+32

a₂₂ = 26

For a₂₃

If R1 = 5, R2 = 3

a₂₃ = -3R2+4R1

a₂₃ = -3(3)+4(5)

a₂₃ = -9+20

a₂₃ = 11

Hence the resulting matrix will be:

[tex]\left[\begin{array}{ccc}-3&8&5\\-9&26&11\end{array}\right][/tex]-3R2+4R1

Answer:

[-3       5  2]

[-36  23  -1]

Step-by-step explanation:

Note abidemiokin did the steps right just has the "given" wrong.

Given the matrix A

[-3  5  2]

[ 8 -1   3]

We are to find the matrix that results from the elementary row operations represented by −3R2+4R1

R2 means row 2

R1 means row 1

Applying the elementary row operation will change the second row of the matrices.

For the first column, second row (a₂₁)

If R1 = -3, R2 = 8

a₂₁ = -3R2+4R1

a₂₁ = -3(8)+4(-3)

a₂₁ = -24-12

a₂₁ = -36

For a₂₂

If R1 = 5, R2 = -1

a₂₂ = -3R2+4R1

a₂₂ = -3(-1)+4(5)

a₂₂ = 3+20

a₂₂ = 23

For a₂₃

If R1 = 2, R2 = 3

a₂₃ = -3R2+4R1

a₂₃ = -3(3)+4(2)

a₂₃ = -9+8

a₂₃ = -1

Hence the resulting matrix will be:

[-3       5  2]

[-36  23  -1]   -3R2+4R1

Answer:

50 leaves, 15 turkeys

Step-by-step explanation:

set up an equation

l = leaves

t = turkeys

l = 2t+20

l = 4t-10

2t+20=4t-10

30=2t

15=t (so that means that there would be 15 turkey decorations, but we're not            done yet)

substitute (either equation):

l = 2(15)+20

l = 30+20

l = 50 (so this means there would be 50 leaves)

Answer:

Step-by-step explanation:

Point F is plotted at (5, 4)

Translate ΔABC so that point B maps to point G.

B(1, -1) → G(0, 3)  

Rule for the translation,

(x, y) → [x - 1, y + 4]

By this rule,

Point C will map the point,

C(-1, -2) → C'[(-1 - 1), (-2 + 4)]

             → C'(-2, 2)

A(-4, 0) → A'[(-4 - 1), (0 + 4)]

           → A'(-5, 4)

Now reflect these points across y-axis.

Rule for the reflection across y-axis,    

(x, y) → (-x, y)

Points after reflection will be,

A'(-5, 4) → F(5, 4)

B'(0, 3) → G(0, 3)

C'(-2, 2) → H(2, 2)

Distance formula,

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

AB = [tex]\sqrt{(1+4)^2+(-1-0)^2}[/tex] = [tex]\sqrt{26}[/tex]

BC = [tex]\sqrt{(-2+1)^2+(-1-1)^2}[/tex] = [tex]\sqrt{5}[/tex]

CA = [tex]\sqrt{(-4+1)^2+(-2-0)^2}[/tex] = [tex]\sqrt{13}[/tex]

FG = [tex]\sqrt{(5-0)^2+(4-3)^2} =\sqrt{26}[/tex]

GH = [tex]\sqrt{(2-0)^2+(2-3)^2}=\sqrt{5}[/tex]

HF = [tex]\sqrt{(4-2)^2+(5-2)^2}=\sqrt{13}[/tex]

AB ≅ FG, BC ≅ GH, CA ≅ HF          

By the SSS property Triangle congruence theorem, ΔABC ≅ ΔFGH

Answer:

Answer:

Y=2x-1

Step-by-step explanation:

In order to find the slope, its rise over run. So you would move from (0,-1) to the next point it intercepts, (1,1) and find it from there

As for the Y-Intercept, it would just be wherever the line connects with the Y axis, which happens to be (0,-1) or Negative 1.

15 coops are needed for 108 pigeons

The unitary method is  a technique for solving a problem but first finding the value of a single unit , and then finding the necessary value by multiplying the single unit value

using  unitary method

Total pigeon = 108

each coop can hold = 7 pigeons

7 pigeons are held by = 1 coop
