Cycle paths inc, makes bicycles,tricycles,and unicycles. last week they made 88 more bicycles than unicycles, and 5 times as many tricycles as unicycles. if they made 40 more bicycles than tricycles, how many unicycles did they make

Answers

Let's name variables:
 x = bicycles
 y = tricycles
 z = unicycles
 We write the following system of equations:
 x = 88 + z
 y = 5z
 x = 40 + y
 We solve the equation system for z:
 1) x = 40 + y
 2) y = 5z
 3) x = 88 + z
 Substituting x and y in equation 1:
 88 + z = 40 + 5z
 We cleared z:
 4z = 88-40
 z = 48/4
 z = 12
 Answer:
 They did make 12 unicycles

Quadrilateral ABCD ​ is inscribed in this circle.



What is the measure of angle B?

Enter your answer in the box.

m∠B=
°

Answers

(6x+19)° + x° = 180°
7x° = 180°-19°
7x° = 161°
x = 23°

m∠B = 6(23) + 19
= 157°

Answer:

∠B=157°

Step-by-step explanation:

It is given that Quadrilateral ABCD ​is inscribed in the circle.

Also, we know that if the Quadrilateral ABCD ​ is inscribed in the circle, then the opposite angles of the quadrilateral are supplementary by the property of circles. Then,

∠B+∠D=180°

⇒[tex]x+6x+19=180[/tex]

⇒[tex]7x+19=180[/tex]

⇒[tex]7x=161[/tex]

⇒[tex]x=23^{{\circ}}[/tex]

Thus, the value of ∠B=6x+19=6(23)+19=138+19=157°.

Wendy took a trip from one city to another, a distance of 580 mi. she traveled part of the way by bus, which arrived at the train station just in time for wendy to complete her journey by train. the bus averaged 40 mi/h, and the train averaged 80 mi/h. the entire trip took 9 1 2 h. how long did wendy spend on the train?

Answers

If he traveled x mi by bus, then the time taken using bus is x/40 hours
and therefore, she took (580-x) mi by train, thus the time taken with train was (580-x)/80 hours.
Hence, x/40 +(580-x)/80 = 9.5 hours
             80(x/40) +80 (580-x)/80 =  (9.5)80
                = 2x + 580-x = 760
                              x= 760-580
                              x = 180
Thus the train covered a distance of  (580-x) =580-180 = 400
Hence, Wendy took 400/80 = 5 hours on the train

The Mid-Atlantic Ridge is a spreading crack between crack between continental plates and it moves apart at 2.5 cm per year. New York is 5567 km from London. In 1,000,000 years, how many far apart will New York be from London.

Answers

In 1,000,000 years, if the Mid-Atlantic Ridge continues to crack at a constant rate, New York and London will be 5592 km away from each other. I found this out by using the unit rate 2.5 cm per year to find out that in 1 million years it would be 2,500,000 cm. There are 100,000 cm in a kilometer. Therefore 2,500,000 cm is equivalent to 25 km. Add the 25 km to 5567 km to get 5592 km as the distance between the two cities.

-(-(-)(-)(-10x))=-5 solve for x

Answers

-(-(-)(-)(-10x)) = -5

We need to cancel out the negatives, so we need to simplify this.

To make things a bit easier for you, we can begin by counting out how many negatives we have. After counting, you should have a negative number count of 5. However, one of the negatives is apart of (-10x) so we'll have 4 negatives and then an extra negative in with 10x.

Remember that "-" could also be looked at as "-1."

So, if we break this down into smaller parts and substitute "-" into "-1," then this'll look like this :

-1 × -1 × -1 × -1 × (-10x) = -5

Remember that a negative times a negative is always a positive.

So, since there are four negatives, then you just multiply it all together.

This results in 1 × (-10x) = -5

Simplify.

-10x = -5

Now, you simply divide both sides by -10.

-10x ÷ -10 = -5 ÷ -10

Simplify.

x = 1/2

Find the probability that the student is male or a nursing major.

Answers

the correct question is
The table below shows the number of male and female students enrolled in nursing at a particular university for a recent semester. ​(a) y Find the probability that a randomly selected student is male or a nursing major.

see the attached table

a) the probability that a randomly selected student is​ male, or a nursing major
total students=[1151+2409]=3560
total male=[98+1053]=1151
P (selected student is​ male)=1151/3560=0.3233
total nursing mayor=[98+741]=839
P (selected student is​ nursing major)=839/3560=0.2357
P(selected student is​ male, or a nursing major)=0.3233+0.2357=0.5590

the answer is 0.5590  (55.90%)
Final answer:

The probability that a student is male or a nursing major is expressed by the formula P(M OR N) = P(M) + P(N) - P(M AND N), which requires actual data to calculate.

Explanation:

To find the probability that a student is male or a nursing major, we can use the principle of addition in probabilities. Let's denote P(M) as the probability that a student is male, P(N) as the probability that a student is a nursing major, and P(M AND N) as the probability that a student is both male and a nursing major. The formula for the probability of either event occurring is given by P(M OR N) = P(M) + P(N) - P(M AND N). We need actual data to calculate these probabilities.

Since we don't have the actual probabilities, we can only provide the symbolic representation of the required probability as P(M OR N). However, if the events of being male and majoring in nursing are mutually exclusive (which in reality, they are not), the probability would simplify to just the sum of the two individual probabilities, P(M) + P(N).

Use the three steps to solve the problem. Betty has 10 more dimes than quarters. If she has $3.45, how many coins does she have?

Answers

Step 1-------> set variables.
Let
x-----------> number of dimes
y-----------> number of quarters 

Step 2:  set the equation and solve for the variable
we know that
0.10 x+0.25 y=3.45---------------> 10x+25y=345   equation (1)
x=y+10  equation (2)
substituting 2 in 1
10[y+10]+25y=345----> 10y+100+25y=345
35y=345-100-----------> y=245/35=7
x=y+10--------> x=7+10=17

Step 3:  plug in the value of x and y from last step into the variables.

y=7--------> number of quarters coins
x=17-------> number of dimes coins

She has (7+17)=24 coins in total



If we assume the quarters are x, then the dimes are 10+x
Thus, 0.25x + 0.1(10+x) = 3.45
         = 0.25x +1 +0.1 x = 3.45
        = 0.35 x = 3.45 -1
         = 0.35x = 2.45
                   x = 7
Therefore, the quarters are 7, while the dimes were 17,
Thus a total of 24 coins

The sides of a square are 5^2/5. What is the area of the square?

A. 5^4/5 square inches

B. 5^4/25 square inches

C. 25^4/5 square inches

D. 25^4/25 square inches

Answers

1. A square is a figure with four sides that have the same lenght. So, to solve this problem and calculate the area of the square, you must apply the following formula:

 A=(s)(s)
 A=s²

 "A" is the area of the square.

 "s" is the lenght of the side of the square.

 2. So, the lenght of the side given in the problem is 5^2/5 inches (s=5^2/5 inches). Therefore, you only have to substitute this value into the formula A=s².

 3. Then, you obtain:

 A=s²
 A=(5^2/5 inches)²
 A=5^4/5 inches²

 What is the area of the square?

 The answer is: A. 5^4/5 square inches.

You sell bracelets for $2 each and necklaces for $3 each at a local flea market. You collect. $95, selling a total of 37 jewelry items. How many of each type of jewelry did you sell?

Answers

16 bracelets. 21 necklaces.
Write a system of equation based on the problem
For an instance, b stands for the number of bracelets, n stands for the number of necklaces.
⇒ Total collected money is $95, $2 per bracelet, $3 per necklace
     2b + 3n = 95  (first equation)
⇒ 37 jewelry items have been sold
    b + n = 37

Find the number of necklaces (n) by eliminating the number of bracelets (b) from the equation system
2b + 3n = 95
  b +   n = 37     (multiply by 2)
----------------------------------------
2b + 3n = 95
2b + 2n = 74
---------------- - (substract)
          n = 21

Find the number of bracelets by substituting the value of n to either of the equations
b + n = 37
b + 21 = 37
b = 37 - 21
b = 16

Type of jewelry have been sold: 16 bracelets, 21 necklaces

there are 1800 pictures could fit on the wall.

Answer:

1800 pictures could fit on the wall.

Step-by-step explanation:

If the area of a space is given as A and this space is to be filled by pictures of area A' then number of pictures will be = [tex]\frac{A}{A'}[/tex]

Now we know area of wall is A and area of picture is A'.

Length and width of wall = 3.6×1.8 m

So area of the wall A = 3.6×1.8 = 6.48 m²

Dimensions of one picture = 6×6 cm Or 0.06×0.06 m

So are of one picture A' = 0.0036 m²

Therefore, Number of pictures on the wall = [tex]\frac{A}{A'}[/tex] = [tex]\frac{6.48}{0.0036}=1800[/tex]

Number of pictures required to cover the wall = 1800
