Yes he is correct

Given a triangle ABC, the sum of the lengths of any two sides of the triangle is greater than the length of the third side. In the words of Euclid: In any triangle two sides taken together in any manner are greater than the remaining one.

If we add the two sides 12 and 18 we get 30 so the third side must be greater than 30. He said greater than 6 so he is right too

Answer:

376 square centimeters

Step-by-step explanation:

When doubled, the new length is 5*2=10 cm, new width is 4*2=8 cm, and new height is 3*2=6 cm.

The surface area of a rectangular prism is given by : [tex]2(lw+wh+lh)[/tex]

Where l is length, w is width, and h is height

Plugging in the new values we get:

[tex]2(lw+wh+lh)\\=2((10)(8)+(8)(6)+(10)(6))\\=2(80+48+60)\\=2(188)\\=376[/tex]

The surface area of the enlarged prism = 376 cm^2

Answer: 376 cm²

Step-by-step explanation:

If the dimensions are doubled then:

length=10cm

width=8cm

height=6cm

You must apply the formula for calculate the surface area of a rectangular prism, whih is shown below:

[tex]SA=2(wl+lh+hw)[/tex]

Where l is the length, w is the width and h is the height.

WHen you substitute values, you obtain the following result:

[tex]SA=2[(8cm*10cm)+(10cm)(6cm)+(6cm)(8cm)][/tex]

[tex]SA=376cm^2[/tex]

Answer:

option D

x≥3

Step-by-step explanation:

Given in the question an inequality

−4x + 2 ≤ −10

rearrange x terms to the left and constant to the right

-4x  ≤ −10 - 2

-4x  ≤ -12

cancel - on both sides, due to sign change inequality will also be change

 4x ≥ 12

  x ≥ 12/4

  x ≥ 3

So, the solution of the inequality is x ≥ 3, x is greater than or equal to 3.

Answer:

x ≥ 3

Step-by-step explanation:

We have given a inequality.

−4x+2 ≤ −10

We have to find the solution of given inequality.

Adding -2 to both sides of given inequality, we have

-4x+2-2 ≤ -10-2

-4x ≤ -12

Cancelling negative sign from both sides of above inequality , we have

4x ≥ 12

Dividing by 4 to both sides of above equations, we have

x ≥ 3 which is the solution of inequality.

The amount of interest earned is $11908 and the total amount is $21248.

Simple interest is calculated just on the loan's principal amount, whereas compound interest is calculated on both the principal and the cumulative interest.

Given that 9340.00 is invested into an account that earns 8.5% simple interest for 15 years.

The simple interest will be calculated by the formula below,

Simple interest = ( P x R x T ) / 100

Simple interest = ( 9340 x 8.5 x 15 ) / 100

Simple interest = $11908.5

The total amount will be,

Amount = $11908.5 + $9340

Amount = $21248.5

The simple interest earned on an investment of $9340.00 at a rate of 8.5% over 15 years is $11919.00. The total amount in the account after 15 years is $21259.00.

To calculate the simple interest earned on an investment, you can use the formula I = P ×  r × t, where I is the interest, P is the principal amount, r is the interest rate (in decimal form), and t is the time in years . In this case:

r (Interest Rate) = 8.5% or 0.085 (since 8 1/2% is the same as 8.5%)

t (Time) = 15 years

Using the formula:

I = $9340.00  ×  0.085 ×  15 = $11919.00

The total simple interest earned over 15 years would be $11919.00. To find the total amount in the account after 15 years, we add this interest to the original principal:

Total = Principal Amount + Interest

Total = $9340.00 + $11919.00 = $21259.00

Therefore, the total in the account after 15 years will be $21259.00.

1.50 acres is the answer.

Final answer:

The mowing rate is 1.5 acres per hour

Explanation:

To find the rate at which a person can mow in acres per hour, we need to use the data provided that a person can mow 0.75 acres in ½ hour. To convert this to a rate in acres per hour, we divide the acres mowed by the hours it took to mow them:

To find the rate at which the person can mow, we need to divide the number of acres mowed by the time taken. In this case, the person can mow 0.75 acres in 1/2 hour.

So, the rate at which the person can mow is 1.5 acres per hour

Rate (in acres per hour) = Acres mowed / Hours taken = 0.75 acres / 0.5 hours = 1.5 acres per hour

Thus, the person can mow at a rate of 1.5 acres per hour.

Answer:

x-12(+4)

Step-by-step explanation:

7x+4x=11x+1x=12x +4.

Answer:

4

Step-by-step explanation:

If two chords intersect externally, then the product of the length of the chord and the length of the part outside the circle is a constant.

Thus from the figure,

we can deduce that:

8×3=6×x

collecting the like terms together we get:

24=6x

x=4

Answer:

x =4

Step-by-step explanation:

Refer the attached figure:

We will use Intersecting secants theorem

Theorem : When two secant lines intersect each other outside a circle, the products of their segments are equal. i.e. [tex]a\times b = c \times d[/tex](refer the attached figure)

So, using this theorem

[tex]x \times 6 = 3 \times 8[/tex]

[tex]x = \frac{24}{6}[/tex]

[tex]x = 4[/tex]

Hence the value of x is 4.

ANSWER

[tex] \frac{113}{18} [/tex]

EXPLANATION

We want to convert

[tex]6 \frac{10}{36} [/tex]

to improper fraction.

Let us first reduce the fractional part to get;

[tex]6 \frac{5}{18} [/tex]

We now multiply 6 by 18 and add 5 and then express the result over 18.

This will give us;

[tex] = \frac{6 \times 18 + 5}{18} [/tex]

[tex] = \frac{108 + 5}{18} [/tex]

[tex] = \frac{113}{18} [/tex]

To convert the mixed number 6 10/36 to an improper fraction, first simplify the fraction to 5/18. Then multiply the whole number by the denominator (6 * 18 = 108) and add the numerator (108 + 5) to get 113/18, which is in its lowest terms.

To convert the mixed number 6 10/36 to an improper fraction in its lowest terms, follow these steps:

First, simplify the fractional part of the mixed number by dividing the numerator and denominator by their greatest common divisor. In this case, 10/36 can be simplified because 2 is the greatest common divisor of 10 and 36. So, 10 \/ 2 = 5 and 36 / 2 = 18, which gives us 5/18.

Next, convert the mixed number to an improper fraction by multiplying the whole number by the denominator of the fraction then adding the numerator. 6 (the whole number) \\times 18 (the new denominator) = 108. Then add the numerator: 108 + 5 = 113.

The result is the improper fraction 113/18.

This improper fraction 113/18 is already in its lowest terms as the numerator and denominator have no common factors other than 1.

[tex]\large\boxed{P=60.56\ m}[/tex]

Step-by-step explanation:

The formula of an area of a rectangle:

[tex]A=lw[/tex]

l - length

We have

[tex]A=229.2\ m^2\\\l=15\ m[/tex]

Substitute:

[tex]15w=229.2[/tex]          divide both sides by 15

[tex]w=15.28\ m[/tex]

The formula of a perimeter of a rectangle:

[tex]P=2(l+w)[/tex]

Substitute:

[tex]P=2(15+15.28)=2(30.28)=60.56\ m[/tex]

Answer:

(5, - 6)

Step-by-step explanation:

Given the 2 equations

6x + 3y = 12 → (1)

6x - 5y = 60 → (2)

Multiply (2) by - 1 and add to (1) will eliminate the term in x

- 6x + 5y = - 60 → (3 )

Add (1) and (3) term by term

(6x - 6x) + (3y + 5y) = (12 - 60)

8y = - 48 ( divide both sides by 8 )

y = - 6

Substitute y = - 6 into (1) or (2) and siolve for x

Using (1), then

6x - 18 = 12 ( add 18 to both sides )

6x = 30 ( divide both sides by 6 )

x = 5

Solution is (5, - 6)

The solution to the system of equations 6x + 3y = 12 and 6x - 5y = 60 is x = 2 and y = -6.

The subject of this question is to find the solution to a system of two linear equations. These equations are: 6x + 3y = 12 and 6x - 5y = 60.

To find the solution to these, one way is to subtract one equation from the other to eliminate x. When we subtract the second equation from the first, we get: (6x+3y) - (6x-5y) = 12 - 60. This simplifies to 8y = -48.

Therefore, y = -48 ÷ 8 which gives the solution y = -6. Substituting y = -6 into the first equation gives us 6x = 12 - 3*(-6), which becomes 6x = 12 to get x = 2.

So the solution to this system of equations is x = 2 and y = -6.

Answer:

y = -3x -5

Step-by-step explanation:

Parallel lines are parallel because they never intersect. As such, they have the same slope. The equation 3x - y = 5 can be converted to slope intercept form to find the slope. The slope of the line y = -3x - 7 is -3. Substitute m = -3 and the point (-1,-2) into the point slope form of a line.

[tex]y -y_1 = m(x-x_1)\\y --2 = -3(x --1)\\y + 2 = -3(x+1)\\[/tex]

You can convert the equation to slope intercept form by using the distributive property.

y + 2 = -3(x+1)

y + 2 = -3x - 3

y = -3x - 5

He add $5 more each month

Step-by-step explanation:

* Lets consider this problem as an arithmetic sequence because

 he add every month x dollars more

∵ He start with 50 dollars ⇒ a (1st amount)

∵ He add x dollars every month ⇒ d

∵ He did that for 36 months ⇒ n

∵ He saved 4950 dollars  ⇒ Sn

∵ Sn = n/2[2a + (n - 1)d]

* Where Sn is the total money after n months

 a is the first amount he saved

 d is the money he add more each month

∴ 4950 = 36/2[2(50) + (36 - 1)(x)]

∴ 4950 = 18[100 + 35x]

∴ 4950/18 = 100 + 35x

∴ 35x = 275 - 100 = 175

∴ x = 175/35 = 5 dollars

Answer:

Mike added $5 more each month.

Step-by-step explanation:

We are given that Mike started saving money by putting $50 aside. Each month, he adds more money than the previous month and so by the end of 36 months, he saved $4950.

Assuming this to be an arithmetic sequence:

[tex]S_n = \frac{n}{2} (2a+(n-1)d)[/tex]

where [tex]S_n=4950[/tex], [tex]n=36[/tex], [tex]a=50[/tex] and [tex]d= x[/tex].

Substituting the given values in the above formula to find how much more money does he add each month.

[tex]4950 = \frac{36}{2} (2 \times 50+(36-1)d)[/tex]

[tex]4950=1800+630x[/tex]

[tex]x=\frac{3150}{630}[/tex]

[tex]x=5[/tex]

Therefore, Mike added $5 more each month.
