Answer: $40.50

Step-by-step explanation:

Since 15% of his total earnings was from raking leaves. The earning from taking leave will be:

= 15% × $90

= 0.15 × $90

= $13.50

Earnings from mowing lawns = $36

The earnings from walking dogs will be:

= $90 - $36 - $13.50

= $40.50

Answer:

40

Step-by-step explanation:

(2x+1/(2x))^5 *(2x -1/(2x))^5

= ((2x)^2 -1/(2x)^2)^5 (a+b)*(a-b) =a2-b2

= (4x^2-1/4(x)^2)^5

now

x =4x^2. ,a = 1/4(x)^2 ,n =5

we have

general term = Cr *x^r *a^(n-r)

= Cr * (4x^2)^r * (1/4(x)^2)^(n-r)

= Cr *4^r * X^2r * 1/( 4^(n-r) *x^(2n-2r)

= Cr * 4^r/4^(n-r) * x^(2r)/x^(2n-2r)

= Cr * 4(2r-n) *x(4r-2n)

now for x^2

4r-2n = 2

4r -10=2

4r =12

r = 3

now for coeff

C(5,3) * 4^(2*3-5)

5!/(3!*(5-3)!) * 4

5*4/(2*1)*4

The conic section as a collection of points(loci) on a plane can be defined in this way .

A conic section is a curve obtained by intersecting a cone with a plane. In Algebra , There are  four main types of conic sections:

circles, parabolas, ellipses and hyperbolas. Each of these conic sections has different characteristics and formulas that help us solve various types of problems.

A locus (plural: loci) (Latin word for "place", "location") is a set of all points (commonly, a line, a line segment, a curve or a surface), whose location satisfies or is determined by one or more specified conditions.

According to the question

There are 4 main types of Conic section :

circles, parabolas, ellipses and hyperbolas. Each of these conic sections has different characteristics and formulas

Loci for circle : The locus of a circle is defined as a set of points on a plane at the same distance from the center point.

Loci for parabola : A parabola is a locus of points that are equidistance form a focus and a directrix .

Loci for hyperbola: A hyperbola is the locus of points such that the absolute value of the difference between the distances from to and to is a constant.

Loci for ellipse: An ellipse is the locus of all those points in a plane such that the sum of their distances from two fixed points in the plane, is constant. The fixed points are known as the foci (singular focus), which are surrounded by the curve.

Hence, The conic section as a collection of points(loci) on a plane can be defined in this way .

Answer: here is your answer

Step-by-step explanation:

You can put this solution on YOUR website!

+t+ = traveler's speed in ft/sec

+w+ = walkway's speed in ft/sec

given:

+t+-+w+=+2+

+t+%2B+w+=+6+

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

Add the equations

+2t+=+8+

+t+=+4+

and

+t+%2B+w+=+6+

+w+=+2+

The traveler's speed off the walkway is 4 ft/sec

The speed of the moving walkway is 2 ft/sec

Answer:

80 pages

Step-by-step explanation:

Point slope Equation is :

y = mx + c

In the above question

y = 310 pages

x = number of days = 10 days

m= 23 pages per day

c = ?? Unknown

c = y - mx

c = 310 - 23 × 10

c = 310 - 230

c = 80 pages

She will still have 80 pages left to read after 10 days

$72 would be the retail price

Step-by-step explanation:

Answer:

i think 7 maybe?

Answer:

0 = 0 miles

1 = 1.5 miles

2 = 3 miles

3 = 4.5 miles

4 = 6 miles

5 = 7.5 miles

Step-by-step explanation:

multiply each hour by 1.5

If a garden snail travels 1.5 miles per hour, then when 0 hours pass, it would have travelled 0 miles (no time has passed).

After 1 hour, it would have travelled 1.5 miles.

After 2 hours, it would have travelled 3 miles (1.5 miles × 2 hours).

After 3 hours, it would have travelled 4.5 miles (1.5 miles × 3 hours).

After 4 hours, it would have travelled 6 miles (1.5 miles × 4 hours).

After 5 hours, it would have travelled 7.5 miles (1.5 miles × 5 hours).

I hope this helps!

Answer:

The average speed is 7.5 [tex]\frac{ m}{ s}[/tex]

Step-by-step explanation:

Speed ​​is a physical quantity that expresses the relationship between the space traveled by an object and the time used for it.

Then, the average speed relates the change in position to the time taken to effect that change:

[tex]speed=\frac{change in position}{change in time}[/tex]

The change in position is the difference between the final position and the initial position, while the change in time is the difference between the final and initial time.

In this case, the starting and ending positions are calculated by replacing the times in the function of the distance d (t):

d(5)= 0.5*5²= 12.5 m

d(10)= 0.5*10²= 50 m

So:

Replacing in the definition of speed:

[tex]speed=\frac{37.5 m}{5 s}[/tex]

and solving you get:

speed= 7.5 [tex]\frac{ m}{ s}[/tex]

The average speed is 7.5 [tex]\frac{ m}{ s}[/tex]

Answer:

I think quadrilateral and rhombus.

Step-by-step explanation:

Answer:

40.32 cm²

Step-by-step explanation:

The area of the small rectangle = 7 × 4 = 28 cm²

Given the ratio of the sides of similar rectangles = a : b , then

the ratio of the areas = a² : b²

Here ratio of sides = 4 : 4.8 = 1 : 1.2

ratio of areas = 1² : 1.2² = 1 : 1.44

Let x be the area of the larger rectangle then by proportion

[tex]\frac{1}{28}[/tex] = [tex]\frac{1.44}{x}[/tex] ( cross- multiply )

x = 40.32

Area of larger rectangle is 40.32 cm²
