Answer:

a.) Money left = $1

b) No

Step-by-step explanation:

Given - You have $15. It costs $ to ride each ride once,

To find - a. How much money do you have left if you ride each ride once?

              b. Do you have enough money to ride each ride twice? Explain.

Proof -

As it is not given in the question that, how much cost to ride each ride once.

Let us assume that,

The cost for each ride = $2

Total rides  = 7

Now,

Total money we have = $15

a.)

Given, cost for 1 ride = $2

⇒ Cost for 7 rides = 7×$2 = $14

∴ Money left =  $15 - $14 = $1

b.)

Given,

Cost for 1 ride = $2

Cost of 1 ride if we ride twice = 2×$2 = $4

Cost of 7 rides if we ride twice = 7×$4 = $28

As $28 > $15

So, we cannot ride each ride twice.

I dont know lol...........

Answer:

there is two solutions to that problem. you can find x is equal to two numbers.

Answer: hello your question is not well written but it seems you are asking for the Total distance covered during the rides hence i will give you a general solution

Total distance travelled during rides = 16.36 km

Total duration of rides = 1 hour

Step-by-step explanation:

Given that :

b = number of hours from house to beach

p = number of hours from beach to park

since the total duration of the rides = 1 hour

hence: b + p = 1 ------ ( 1 )

Also ; speed from house to beach = 18 km/hr

         speed from beach to park = 15 km/hr

Given that distance covered in both directions are equal and distance = s * t

Hence distance covered :   18b = 15p ------  ( 2 )

determine the total distance travelled

b + p = 1 ------ ( 1 )

18b = 15 p ----- ( 2 )

from equation 1 : b = 1 - p

18 ( 1 - p ) = 15p

18 = 15p + 18p

p = 18 / 33 = 6/11

back to equation 1

b + 6/11 = 1

hence b = 1 - 6/11 = 5/11

Distance covered in one direction

18 ( 5/11 ) = 15 ( 6/11 )

90 / 11  = 90 /11

hence Total distance covered = ( 90 / 11 ) * 2 = 16.36 km

Answer:

=25343 grams or 25 kg 343 g.

Step-by-step explanation:

1 kg = 1000 g

∴ 4 kg = 4000 grams

and the 4 kg 250 g would equal = 4250 grams.

∴ 2 kg = 1000 g

2 kg 90 g = 2000 grams + 90 g = 2090 grams

∴ 19 kg = 19000 grams

and 19 kg 3 grams = 19000 grams + 3 grams = 19003 grams

now we will add all of the values together to get the final answer.

4250 grams + 2090 grams + 19003 grams = 25343 grams or 25 kg 343 g.

Answer:

59.85

Step-by-step explanation:

The scores on a mathematics exam have a mean of 70 and a stadard deviation of 7. Find the x-value that corresponds to the z-score -1.45.

We solve the above question using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean = 70

σ is the population standard deviation = 7

z = -1.45

Hence:

-1.45 = x - 70/7

Cross Multiply

-1.45 × 7 = x - 70

-10.15 = x - 70

x = -10.15 + 70

x = 59.85

Answer:

9.55 cm

Step-by-step explanation:

A quadrant of a circle is 1/4 of a circle.

Since the curved edge is 15 cm, a full circle would be 60 inches.

60/Pi = diameter

diameter = 60/3.14 = 19.11 cm

diameter/2 = radius

radius = 19.22/2 = 9.55 cm which is the length of a straight edge.

Answer:

=4x^2−20xy+25y^2

Step-by-step explanation:

Answer:

x= 73

y= 13

Step-by-step explanation:

The sum of the angles opposite the exterior angle = the exterior angle so

x= 141-68

x= 73

The angle sum of a triangle= 180.

180-68-73= 39

since there are 3 "y"s we need to divide 39 by 3

39/3= 13

Answer:

a. The width of the rectangle is x-2cm

b. length is 21.5 cm and breadth is 19.5cm

c. area is 419.25 cm sq.

Step-by-step explanation:

Let the length be x and the breadth be x-2

perimeter = 84 = 2(l+b) = 2×(x+x-2)

2×(2x-2)=84

4x-2 = 84

4x = 86

x= 86/4

x= 21.5

length is 21.5 and breadth is 21.5-2 = 19.5

area = l×b

= 21.5 ×19.5

= 419.25cmsq.

Answer:

1/3= 137.51 so b

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]\alpha =\frac{l}{r}[/tex]

alpha are the angle in radian.

l= lenght of de arc=12cm

r=radius=5cm

[tex]\alpha =\frac{12}{5} \\\\[/tex]

Converting the radian angle to degrees:

α--->θ

π--->180°

θ=(180°*α)/π

using the fact that: α=12/5

θ=(180°*12)/5

θ=432°/π

θ=137,5098°

θ=137,51°

Step-by-step explanation:

The man's basic wage for the week is A = $ 192.50

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The man's basic wage for a 40 hour week is $160.00. This means that his hourly rate is:

$160.00 / 40 hours = $4.00 per hour

For the overtime hours, he is paid $5.00 per hour. So, for the 6 1/2 hours of overtime, he will earn:

6.5 hours x $5.00/hour = $32.50

On simplifying the equation , we get

To find his total wage for the week, we need to add his basic wage to his overtime pay:

Total wage = Basic wage + Overtime pay

Total wage = $ 160.00 + $ 32.50

Total wage = $ 192.50

Therefore, the man's wage for that week is $ 192.50

Hence , the equation is A = $ 192.50

Step-by-step explanation:

Given sequence is: 4, 28, 196, 1372

28/4 = 7

196/28 = 7

1372/196 = 7

Since, the ratio of any two consecutive terms is same, so it is a geometric sequence.

Answer:

Selling Price=$562.50

Step-by-step explanation:

Given cost price of the treadmill= $750

Loss% = 25%

We know, the formulae for selling price = (100 -loss%) X cost price/100

= (100 - 25)X 750/100

= (75)750/100

= 75 × 750/100

= $562.50

The formula for finding the area of any regular polygon if you know the length of one side and the apothem: A = (n × s × a)2 A = ( n × s × a ) 2 , where n is the number of sides, s is the length of one side, and a is the apothem.

Answer: d) 60

Step-by-step explanation:

so two numbers a+b=90 and also a-b=30

Lets assume a is the larger number. So we can plug and chug for time purposes I will explain why 60 is the answer. so 60-30=30 so b would be 30 and a would be 60. Also a+b or 60+30= 90 and that is the case the smaller number is 30 and the larger number is 60
