Answer:

c on edge

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

the scaling factor is 1.5 to go from DEF to QRS.

so,

EF × 1.5 = RS = 6

EF = 6 / 1.5 = 6/1 / 3/2 = 6×2 / 1×3 = 12/3 = 4

Answer:

Step-by-step explanation:

AC and D are all wrong. The all add or subtract something from 3 which is not going to keep the two sides of the equation equal.

Only B is correct. To get the two sides equal, you need to multiply the powers by the same constant. B does this. The powers and the constant 1/3 * 3 are the same on both sides.

Answer:

Answer:

x=−3 & x=4

Step-by-step explanation:

Step 1: Subtract 5x+3 from both sides.

x2+4x−9−(5x+3)=5x+3−(5x+3)

x2−x−12=0

Step 2: Factor left side of equation.

(x+3)(x−4)=0

Step 3: Set factors equal to 0.

x+3=0 or x−4=0

x=−3 or x=4

Answer:

x=4  x=-3

Step-by-step explanation:

x^2 + 4x-9 = 5x + 3

Subtract 5x from each side

x^2 + 4x-5x-9 = 5x -5x+ 3

x^2 +-x-9 =  3

Subtract 3 from each side

x^2 -x-9-3 =  3-3

x^2 -x -12 =0

Factor

What 2 numbers multiply to -12 and add to -4

-4*3 = -12

-4+3 =-1

(x-4)(x+3) =0

Using the zero product property

x-4 =0  x+3 =0

x=4  x=-3

Answer:  Choice B) 60 roses and 10 carnations

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

Explanation:

r and c are positive whole numbers.

r+c = total number of flowers = 50, since 50 orders are made.

The first equation to set up is r+c = 50.

This equation can be solved to get r = 50-c.

------------------

3r = cost of all the roses only, in dollars

1.5c = cost of all the carnations only, in dollars

3r+1.5c = total cost of all the flowers = 195 dollars

3r+1.5c = 195

------------------

Let's apply substitution to solve

3r+1.5c = 195

3(50-c)+1.5c = 195

150-3c+1.5c = 195

-1.5c+150 = 195

-1.5c = 195-150

-1.5c = 45

c = 45/(-1.5)

c = -30

That's not good. We shouldn't get a negative value.

It turns out that the condition r+c = 50 should be ignored. Notice how none of the answer choices listed have r+c leading to 50.

So we'll only focus on the equation 3r+1.5c = 195

-----------------

If we plugged in r = 100 and c = 100, then we get

3r+1.5c = 195

3(100)+1.5(100) = 195

300+150 = 195

450 = 195

Which is false. So we can rule out choice A

Let's repeat those steps for choice B

3r+1.5c = 195

3(60)+1.5(10) = 195

180 + 15 = 195

195 = 195

So that works out. I have a feeling your teacher meant to say "70 orders" instead of "50 orders". If so, then the equation r+c = 50 would be r+c = 70 and everything would lead to choice B as the final answer.

Choices C and D are similar to that of choice A, so they can be ruled out.

Answer:

Internal height is approximately 28.5714285714286 cm

Internal surface area is roughly 9628.57142857143 square cm

Round the values however you need to

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

Step-by-step explanation:

Work Shown:

1 L = 1000 mL

1 L = 1000 cm^3

60 L = 60,000 cm^3 (multiply both sides by 60)

The cooler has volume of 60,000 cubic cm. Let V = 60000

Assuming the cooler is a rectangular prism (aka a block), then we can say

volume = length*width*height

V = L*W*H

60000 = 60*35*H

60000 = 2100H

2100H = 60000

H = 60000/2100

H = 28.5714285714286 which is approximate

And the surface area (SA) is

SA = 2*(LW + LH + WH)

SA = 2*(60*35 + 60*28.5714285714286 + 35*28.5714285714286)

SA = 9628.57142857143 which is also approximate

Units for the surface area are in square centimeters.

Answer:

The proportional relationship is same

Step-by-step explanation:

Generally, we can get the unit rate by dividing the y-value by the x-value

This will be;

9/2 or 18/4 or 27/6 = 4.5

from what we have y = 4.5x

Now, as we can see, the proportional relationship is same

Answer:

Perimeter of ΔPRS = 35.91 units

Step-by-step explanation:

From the figure attached,

By applying triangle sum theorem in the given triangle PRS,

m∠P + m∠R + m∠S = 180°

45° + m∠R + 60° = 180°

m∠R = 75°

By applying sine rule,

[tex]\frac{\text{sinP}}{RS}= \frac{\text{sinS}}{PR}=\frac{\text{sinR}}{PS}[/tex]

[tex]\frac{\text{sin}(45^{\circ})}{10}= \frac{\text{sin}(60^{\circ})}{PR}=\frac{\text{sin}(75^{\circ})}{PS}[/tex]

[tex]\frac{\text{sin}(45^{\circ})}{10}= \frac{\text{sin}(60^{\circ})}{PR}[/tex]

PR = 12.25 units

[tex]\frac{\text{sin}(45^{\circ})}{10}=\frac{\text{sin}(75^{\circ})}{PS}[/tex]

PS = 13.66 units

Perimeter of triangle PRS = PR + PS + RS

                                            = 12.25 + 13.66 + 10

                                            = 35.91

Answer:

The equation has only one solution, x = -9

Step-by-step explanation:

We want to find how many solutions the equation:

8x = -9 + 7x

has.

To find it, let's simplify the equation.

First, let's move all the terms with x to the left side, and the terms without x to the right side:

8x - 7x = -9

(8 - 7)*x = -9

1*x = -9

x = -9

So we can see that we have only one solution, x = -9

Answer:

$2475  or $1875

Step-by-step explanation:

Assuming the question meant to say $25 less than the original price, it would be $2475 because $2500-$25= $2475

However, if the question meant to say that Sam bought the iron for 25% less than the original price, it would be $1875 because 2500*0.25= $625

$2500-$625= $1875

Answer:

Area of Hexagon = 1,995 m² (Approx.)

Step-by-step explanation:

Given:

Length of apothem = 24 m

Number of total sides = 6

Find:

Area of Hexagon

Computation:

Side = a[2tan(180/n)]

Side = 24[2tan(180/6)]

Side = 24[2tan(30)]

Side = 27.71 m (Approx.)

Area of Hexagon = [3√3a²]/2

Area of Hexagon = [3(1.732)(27.71)²]/2

Area of Hexagon = [3(1.732)(767.8441)]/2

Area of Hexagon = 3989.71794 / 2

Area of Hexagon = 1994.8589

Area of Hexagon = 1,995 m² (Approx.)

Answer:

cotA-cosec4A

Step-by-step explanation:

LHS=1/sin2A + cos4A/sin4A

=1/sin2A +cos4A/2sin2.Acos2A

=1/sin2A (1+cos4A/2cos2A)

=1/sin2A(2cos2A+cos^2A-sin^3A)/2Cos2A

=1/sin2A(2cos2A+cos^2Ac-(1-cos^2A)/2cos2A

=1/sin2A(2cosA(1+cos2A)-1)/2cos2A

=1/sin2A(1+cos2A-1/2cos2A)

=1+cos2A/sin2A-1/sin2A.cos2A

=1+2cos^A-1/2sinA.cosA-1/sin4A

=2cos^A/2sinA.cosA-1/sin4A

=cosA/sinA-1/sin4A

=cotA-cosec4A

Answer:

Step-by-step explanation:

Let the two numbers be 2x and 3x.

According to the question,

2x+3x=45

5x=45

x=45/5

x=9

so th required numbers are 18 and 27 as

2x=2*9=18

3x=3*9=27

It is given that,

→ Two numbers are in the ratio 2:3.

→ Their sum is 45.

We have to,

find the both required numbers.

Now assume numbers as,

→ 2y and 3y

As per the given information,

→ 2y + 3y = 45

First we can find the value of y,

→ 2y + 3y = 45

→ 5y = 45

→ y = 45/5

→ [y = 9]

The given ratio is,

→ 2 : 3

Let's find the value of 2y,

→ 2y --- {y = 9}

→ 2 × (9)

→ 18

Let's find the value of 3y,

→ 3y --- {y = 9}

→ 3 × (9)

→ 27

Hence, the number is 18 and 27.

Answer:

m=-2

Step-by-step explanation:

As the product of the roots of a quadratic equation is c/a in ax^2+bx+c=0

here a=2, b=+8, c=-m^3

Given c/a=4

-m^3/2=4

-m^3=8

m^3= -8

m=-2.

Answer:

In x dollars,

number of book that can be bought = 1

So, In 1 dollar,

number of books that can be bought = 1/x

Hence in 40 dollars,

number of books that can be bought = 40/x

Answer:

40/x

Step-by-step explanation:

The cost of 1 book is $X.

You bought (?) books for $40.

If you want to know how many books you bought, divide the total cost of books ($40) by the cost of 1 book ($X).

Answer:

Equation for area = 36 = [1/2]x[2x - 1]

Step-by-step explanation:

Given:

Area of triangle = 36 m²

Length of base = 2(Height) - 1

Find:

Equation for area

Computation:

Assume;

Height = x

Area of triangle = (1/2)(b)(h)

36 = (1/2)[2(x) - 1][x]

36 = [1/2]x[2x - 1]

Equation for area = 36 = [1/2]x[2x - 1]
