Number of each type of cards after solving system of equations for given situation of Pedro cards are 29 and68.

Interpretation is Pedro collected 29 football cards and 68 baseball cards.

As given,

Total number of cards=97

Let y=football cards

    x=baseball cards

System of equations are

x + y=97  __(1)

x=y +39    __(2)

Substitute (2) in (1)

y+ 39 +y=97

⇒2y=58

⇒y=29

Substitute y=29 in (2),

x=29 +39

 =68

Therefore, number of each type of cards after solving system of equations are football cards 29 and baseball cards 68.

Interpretation is Pedro collected 29 football cards and 68 baseball cards.

Heidi is able to walk 10/3 miles in 1 hour (60 min).

It is a method for determining the value of a single unit by subtracting the value of multiple units and subtracting the value of multiple units from of the value of a single unit.

Now, for the given question;

It takes Heidi 12 minutes to walk 2/3 miles.

Applying the unitary method.

Then, for in 1 minutes Heidi will walk = 2/(3×12).

For walking in 1 hour or 60 min =  (2×60)/(3×12).

Further simplifying;

In 1 hour = 10/3 miles.

Therefore, Heidi would be be able to walk 10/3 miles in 1 hour.

Linear equations are often organized in slope-intercept form: [tex]y=mx+b[/tex]

To find a linear equation, we often first solve for the slope, and then solve for the y-intercept algebraically.

To find the slope of a perpendicular line, we must find the negative reciprocal of the slope of the reference line.

We're given:

1) Find the slope of the reference line

We can rewrite the reference line to be clearer in slope-intercept form:

[tex]y=-1x+0[/tex]

This means that -1 is the slope.

2) Find the slope of the perpendicular line

The negative reciprocal of -1 is 1. Therefore, the slope of the perpendicular line is 1. Plug this into slope-intercept form:

[tex]y=x+b[/tex]

3) Solve for the y-intercept of the perpendicular line

[tex]y=x+b[/tex]

Plug in the given point (-8,2) and solve for b:

[tex]2=-8+b\\b=2+8\\b=10[/tex]

Therefore, the y-intercept of the perpendicular line is 10. Plug this back into our original equation:

[tex]y=x+10[/tex]

[tex]y=x+10[/tex]

Area of Triangle - A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon. The above figure is a triangle denoted as △ABC. Some real-life examples of triangles include sandwiches, traffic signs, cloth hangers, and a rack in billiards.

The basic formula to find the area of a triangle is,

Area of triangle = 1/2 (b × h);

where b = base and

          h = height of the triangle.

Now , we have been given that -

Base  =5/3 m

Height  = 1/2 m

Find out area of the triangle .

The area of a  triangle = 1/2 x base  x height

Put the values in formula

area of a  triangle = 1/2 x 5/3 x 1/2

area of a  triangle = (1x5x1)/ (2x3x2)

area of a  triangle = 5/12 m².

Hence,  the area in square meters of the given shape is 5/12 .

29 can be written as 29/1 thus 29 is a rational number

By rationalization and algebra properties, the irrational expression 7√3 / (√10 + √3) - 2√5 / (√6 + √5) - 3√2 / (√15 + 3√2) is equivalent to the integer 1.

In this question we find a composite irrational expression formed by a irrational fraction being subtracted by other two irrational fraction. Eliminating the irrational denominators by transforming it into rational numbers is an important step for this question, this can be done by means of rationalization, along with algebra properties.

The complete procedure of this exercise is shown below:

7√3 / (√10 + √3) - 2√5 / (√6 + √5) - 3√2 / (√15 + 3√2)

[7√3 · (√10 - √3)] / [(√10 + √3) · (√10 - √3)] - [2√5 · (√6 - √5)] / [(√6 + √5) · (√6 - √5)] - [3√2 · (√15 - 3√2)] / [(√15 + 3√2) · (√15 - 3√2)]

(7√30 - 21) / 7 - (2√30 - 10) - (3√30 - 18) / (- 3)

(7√30 - 21) / 7 + (10 - 2√30) + (3√30 - 18) / 3

(7√30 - 21 + 70 - 14√30) / 7 + (3√30 - 18) / 3

(49 - 7√30) / 7 + (3√30 - 18) / 3

0.7 birdhouses in 1 day.

how many in 10 weeks ?

for that we need to know how many days are in 10 weeks.

1 week = 7 days

assuming that she is working on the birdhouses also on weekends, that means 10 weeks = 10×7 = 70 days.

and that means she can build

0.7 × 70 = 49 birdhouses in 10 weeks.

now, if she works only Monday to Friday on the birdhouses, then that means

1 week = 5 days

and 10 weeks = 10×5 = 50 days.

and that means she can build

0.7 × 50 = 35 birdhouses in 10 weeks.

if there is really no other information about that, I would use the usual 7 days per week and the first solution (49).

The set of transformations that is performed on triangle ABC to form triangle A′B′C′ is C. A translation 5 units to the left followed by a 180 degree counterclockwise rotation about the origin.

A translation is a geometric transformation when each point in a figure, shape, or space is moved in a specific direction by the same amount. A translation can also be thought of as moving the coordinate system's origin or as adding a constant vector to each point.

In this case, it can be seen that the shape was rotated counterclockwise twice. That's 90° × 2 = 180°

Therefore, the transformation that is performed on triangle ABC to form triangle A′B′C′ is a translation 5 units to the left followed by a 180 degree counterclockwise rotation about the origin.

According to the question, each lap of 25 yards is covered 3 seconds faster than the previous one, so the series become

x , x-3 , x-6 , x-9, ............................

25 * m = 200

m = 200/25

m = 8

As m is the number of laps, and each lap is 3 second faster.

So 8 laps will be 8*3 = 24 seconds faster.
