Answer: 1.6 lawns a week

Step-by-step explanation:

Carlt mowed 2 more lawns than Rocco every week for 5 weeks.

This means that the number of lawns he mowed more than Rocco is:

= 2 * 5

= 10 lawns

If Carlt mowed 18 lawns in those 5 weeks then Rocco mowed:

= 18 - 10

= 8 lawns

Lawns mowed per week by Rocco:

= 8/5

= 1.6 lawns a week

Answer:

we get [tex]Sin X=\frac{12}{13}[/tex]

Option B is correct answer.

Step-by-step explanation:

We need to find the trigonometric ratio Sin X

We know that [tex]Sin X = \frac{Perpendicular}{Hypotenuse}[/tex]

Looking at the figure, we have:

Perpendicular = XY = 24

Base = YZ = 10

Hypotenuse = XZ = 26

Now putting values in the formula and finding value of Sin X

[tex]Sin X = \frac{Perpendicular}{Hypotenuse}\\Sin X =\frac{24}{26}\\Sin X =\frac{12}{13}[/tex]

So, we get [tex]Sin X=\frac{12}{13}[/tex]

Option B is correct answer.

Answer: Choice D)  7.5 inches, 18 inches, 19.5 inches

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

Explanation:

The Pythagorean theorem converse can be used to determine if we have a right triangle or not.

The converse says that if a^2 + b^2 = c^2 is a true equation, then we have a right triangle.

The value of c is always the longest side. The order of 'a' and b doesn't matter (usually b is larger than or equal to 'a'). So we could have [tex]a \le b < c[/tex] or [tex]b \le a < c[/tex], but convention usually leans toward the first inequality mentioned.

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

In choice A, we have the following steps

a^2 + b^2 = c^2

(7.5)^2 + (18)^2 = (21.5)^2

380.25 = 462.25

Since the third equation is false, this means the first equation is false for those a,b,c values. Choice A is not a right triangle. We can cross it off the list.

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

In choice B, we have a = 7.5, b = 19.5 and c = 21.5

So,

a^2 + b^2 = c^2

(7.5)^2 + (19.5)^2 = (21.5)^2

436.5 = 462.25

which is also false. Cross choice B off the list.

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

With choice C we have: a = 18, b = 19.5, c = 21.5

a^2 + b^2 = c^2

(18)^2 + (19.5)^2 = (21.5)^2

704.25 = 462.25

Cross choice C off the list since the third equation is false.

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

In choice D, we have the sides a = 7.5, b = 18, c = 19.5

a^2 + b^2 = c^2

(7.5)^2 + (18)^2 = (19.5)^2

380.25 = 380.25

We get the same number on both sides, so the third equation is true. Consequently, this leads to the first equation being true for those a,b,c values. Choice D is a right triangle, and it's the final answer.

Answer:

-4

Step-by-step explanation:

The formula of an arithmetic sequence is nth term=a+(n-1)d. First term is a and common difference is d.

Let's plug our info in.

-20=12+(9-1)d

-20=12+8d

Subtract 12 from both sides.

-32=8d

Divide both sides by 8.

d=-4

Answer:

We conclude that 49x² - 28x + 4 = 0 has only one real root.

Thus, option B i.e. one real root is the correct option.

Step-by-step explanation:

Given the equation

49x² - 28x + 4 = 0

comparing with the quadratic equation ax² + bx + c = 0 for x, where a ≠ 0,

here

a = 49, b = -28, c = 4

Determining the discriminant b²-4ac

b²-4ac = (-28)² - 4(49)(4)

           = 784 - 784

           = 0

It is clear that the discriminant b²-4ac is equal to zero.

i.e.

b²-4ac = 0

We know that if the discriminant b²-4ac = 0, then the quadratic equation has one real root.

Therefore, we conclude that 49x² - 28x + 4 = 0 has only one real root.

Thus, option B i.e. one real root is the correct option.

Answer:

17 kids 24 adult

Step-by-step explanation:

17+24 = 41

17x1.5=25.5

24x2=48

48+25.5=73.5

For the event , 24 adults and 17 children tickets were sold .

Let :

Now we have the equations :

from (1):

substitute (3) into (2)

2(41-c) + 1.5c = 73.5

82 - 2c + 1.5c = 73.5

-0.5c = -8.5

c = 17

From (3)

a = 41 - 17

a = 24

Hence, 24 adults and 17 children tickets were sold .

Given:

Evan paid his mom back 9.60 which is 20% of the total he owns.

To find:

How much did he owe her to begin with.

Solution:

Let x be the amount Evan owns.

According to the question,

20% of x = 9.60

[tex]\dfrac{20}{100}x=9.60[/tex]

[tex]\dfrac{1}{5}x=9.60[/tex]

Multiply both sides by 5.

[tex]x=48[/tex]

Therefore, Evan owns 48 from his mom.

x=2.5

Answer:

x=2.5

Step-by-step explanation:

3(x+2)=x+11   (distribute 3 to x&2)

3x+6=x+11   (then you subtract x from both sides)

2x+6=11  (subtract 6 from both sides)

Answer:

I'm gonna go a little out of order.

To determine b, find where the line crosses the y-axis. If it's positive, put it as " + " and if it's negative, put it as " - ".

To determine m, find two points on the line that are directly on the number. Example, choose (4, 1) instead of (4.1, 5.2). Go up/down and left/right (while making sure to count) until you reach the second number. going up and right will be considered positive while down and left are considered negative.

Using rise/run, put your number for up/down as a numerator over your left/right, which will be a denominator.

Insert m and b and you're good to go!

Answer:

x = 4

w = 1.5

Step-by-step explanation:

Here, we want to find the value of x

We use the principle of similar triangles here

We have these as;

(x + 2)/6 = x/4

4(x + 2) = 6x

4x + 8 = 6x

6x - 4x = 8

2x = 8

x = 8/2

x = 4

We proceed to get w;

3+w/6 = 3/4

4(3 + w) = 6(3)

12 + 4w = 18

4w = 18-12

4w = 6

w = 6/4

w = 1.5
