Answer:

The answer is 35 plants.

Step-by-step explanation:

The ratio of tomato plant to that of pepper plant = 2:5

Let x be the number of pepper plants for 14 tomato plants.

Now, according to the question:

2:5 = 14:x

14×5 = 2x

x = 70/2 = 35 plants.

Answer:

35 peppers

Step-by-step explanation:

Use cross multiplication

2 tomatoes/5 peppers = 14 tomatoes/x peppers

x peppers = (5*14) / 2 = 35

98 - 3 * 2 * 4 equal to 9 - 2 * 840 + 9 - 6 equal to -7

The evaluation of 14(7) -d 2f when d = 2 and f = 4 is 82.

Two algebraic expressions having the same value and symbol '=' in between are called an equation.

Given:

An expression,

14(7) -d 2f.

To find the value of the expression:

Substitute the given value of d and f.

When d = 2 and f = 4,

the equation is,

14(7) -(2)2(4)

= (14 x 7) - ( 2 x 2 x 4)

= 98 - 16

= 82

The evaluation of the equation when d = 2 and f = 4 is 82.

Therefore, the solution is 82.

Answer:

g(x) has the greater value when x = 2, g(2) is 7 greater than f(2)

Step-by-step explanation:

From the graph, f(2) = 1

g(2) = 0.5(4)² = 8

So g(x) has the greater value when x = 2, g(2) is 7 greater than f(2)

Answer:

Step-by-step explanation:

The surface area of one ornament is twice the area of a cone with radius 2.4 inches and slant height 9.8 inches. The number of bottles of paint required will be found by dividing the total area to be painted by the area covered by one bottle.

__

The area formula for a cone is ...

  A = πr(r +s) . . . . . radius r, slant height s

The area of the double cone ornament will be ...

  A = 2(3.14)(2.4 in)(2.4 +9.8 in) = 183.8784 in²

The surface area of one ornament is about 183.9 square inches.

__

The surface area of 60 ornaments is ...

  60 × 183.8784 in² = 11,032.704 in²

The number of bottles of paint required is ...

  11,032.704 in²/(150 in²/bottle) = 73.55136 bottles

Tim will need 74 bottles of paint for 60 ornaments.

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

Explanation:

Recall that the pythagorean trig identity is [tex]\sin^2 x + \cos^2x = 1[/tex]

If we were to isolate sine, then,

[tex]\sin^2 x + \cos^2x = 1\\\\\sin^2 x = 1-\cos^2x\\\\\sin x = \sqrt{1-\cos^2x}\\\\[/tex]

We don't have to worry about the plus minus because sine is positive when 0 < x < pi/2.

Through similar calculations, [tex]\cos x = \sqrt{1-\sin^2x}\\\\[/tex]

Cosine is also positive in this quadrant.

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

So,

[tex]\frac{\sqrt{1-\cos^2x}}{\sin x}+\frac{\sqrt{1-\sin^2x}}{\cos x}\\\\\frac{\sin x}{\sin x}+\frac{\cos x}{\cos x}\\\\1+1\\\\2[/tex]

Therefore,

[tex]\frac{\sqrt{1-\cos^2x}}{\sin x}+\frac{\sqrt{1-\sin^2x}}{\cos x}=2[/tex]

is an identity as long as 0 < x < pi/2

Answer:

2

Step-by-step explanation:

[tex]=\frac{\sqrt{1-cos^{2}x }}{sinx} +\frac{\sqrt{1-sin^{2}x } }{cosx} \\\\When \:0 < x < \frac{\pi }{2} \\\\=\frac{\sqrt{sin^{2}x } }{sinx} +\frac{\sqrt{cos^{2}x } }{cosx} \\\\=\frac{sinx}{sinx} +\frac{cosx}{cosx} \\\\=1+1\\\\=2[/tex]

Here we use the formula sin²x=1-cos²x and cos²x=1-sin²x.

Answer: 6

Step-by-step explanation:

i got the same question.

Jessica needs another 52.8 cm^3 of material to make the other prism.

For a right triangular prism of base B, height H, and length L, the volume is:

V = (1/2)*B*L*H

Now, we know that the first triangle has a volume of 12.6cm^3, then we can write:

V = 12.6cm^3 = (1/2)*B*L*H

If we dilate the prism with a scale factor of 3, the new dimensions are:

B' = 3B

L' = 3L

H' = 3H

Then the new volume is:

V' = (1/2)*(3B)*(3L)*(3H) = 27*(1/2)*B*L*H

And (1/2)*B*L*H is the original volume, so we can write:

V' = 27*V = 27*(12.6cm^3) = 340.2 cm^3

And she has 300cm^3 and she used 12.6cm^3, so the amount of material that she has left is:

M = 300 cm^3 - 12.6 cm^3 = 287.4 cm^3

Then the amount of material that she needs is:

340.2 cm^3 - 287.4 cm^3 = 52.8 cm^3

So Jessica needs another 52.8 cm^3 of material to make the other prism.

Answer:

109,200 people

Step-by-step explanation:

First change all the percentages into decimals. Then multiply 108,000 by 1.077, because it is 7.7% of the population, while also including the original population. The product of this is 116,316. Then, if you want to find the percent decrease, it would be something out of 100, so 100-6.1=93.9. Changing that into decimal form, 0.939, and multiplying it by 116,316, you get 109,220, which rounds to 109,200.

Answer:

The graph I put is what should match!

Step-by-step explanation:

The cost of a pen is $3.5 while the cost of a pencil is $7

Let the price of pen  be x

Let the price of pencil be y

If Julian was charged $40 for 4 pencils and 8 pens, then;

4y + 8x = 40

y + 2x = 10

y = 10 - 2x .............. 1

Similarly, if Estefania was charged $25 for 6 pencils and 2 pens, then;

6y + 2x = 25

Substitute 1 into 2 to have:

6(10-2x)+ 2x = 25

60 - 12x + 2x = 25

60-10x = 25

10x = 35

x = 3.5

Since y = 10 - 2x

y = 10 - 7

y = 3

Hence the cost of a pen is $3.5 while the cost of a pencil is $7
