Answer:

x=1

Step-by-step explanation:

3/2+ 1/2= 2x

2=2x

Answer:

177 ft below sea level.

Step-by-step explanation:

Initial altitude of the hot air balloon = 282 below sea level

Rate of rise of balloon = 10 ft / second

Time = 12 seconds

Total rise in 12 seconds = Rate of rise of balloon [tex]\times[/tex] Time

[tex]\Rightarrow 10 \times 12[/tex] = 120 ft

Now, we will have to subtract to find the new altitude.

New altitude = 282 - 120 = 162 ft

Now, it is given that balloon Captain lowers the balloon 15 ft.

To find the final altitude, we will have to add it to the previous altitude.

Therefore, the final altitude = 162 + 15 = 177 ft below sea level

Answer:

slope or what y2-y1/x2-x1 use the formula

The coordinate of point S such that QS to SR is 1:3 will be (1,3).

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.

For example (5,3) here 5 will be for the x and 3 will be for the y.

Another example is (9,0) here 9 is for x and 0 is for y.

Given the coordinate Q(2,5) and R(-2,-3)

The intersection ratio is 1 over 3

The coordinate of point S is given by

x = [1(-2) + 3(2)]/(1+3) ⇒ x = 1

y = [1(-3) + 3(5)]/(1+3) ⇒ y = 3

Hence "The coordinate of point S such that QS to SR is 1:3 will be (1,3)".

The maximum number of apples that she can buy is 7.75.

We are given that:

- Apples cost $2 each.

- Mangos cost $1.50 each.

- Mia has $20 to spend.

- Mia must buy no less than 9 apples and mangos altogether.

- Mia decided to buy 3 mangos.

Now,

we can write the following system of equations:

[tex]$\begin{cases}2a + 1.5m \leq 20\\a + m \geq 9\\m = 3\end{cases}$[/tex]

Substituting $m = 3$ into the second equation, we get:

[tex]$a + 3 \geq 9 \Rightarrow a \geq 6$[/tex]

So, Mia must buy at least 6 apples.

To determine the maximum number of apples that she could buy, we can substitute m = 3 into the first equation and solve for a:

[tex]$2a + 1.5(3) \leq 20 \Rightarrow a \leq \frac{20 - 4.5}{2} = 7.75$[/tex]

Therefore, by equation answer will be 7.75.

Answer:

C( They do not intersect, but are coplanar

Step-by-step explanation:

Parallel lines are coplanar (they lie in the same plane) and never intersect.

The statement that is true about parallel lines is that they do not intersect, but are coplanar: Option C is correct.

Lines are 2-dimensional figures that are used to connect two on more points in a xy-plane.

For two lines to be parallel, this means that the lines;

Hence we can conclude that the statement that is true about parallel lines is that they do not intersect, but are coplanar.

Answer:

square root of 40  is greater than side of the square

Step-by-step explanation:

First we find square root of 40

[tex]\sqrt{40} = 6.325[/tex]

Now

given

area of a square is 33 square inches

we know area of square is side square

area of square  = [tex]side^2[/tex]

[tex]side^2 = 33\\\sqrt{side^2} = \sqrt{33}\\side = 5.745[/tex]

Thus, we see length side of square is 5.7 inches

and square root of 40 is 6.325

since

6.325 > 5.7

hence square root of 40  is greater
