Answer:
the number of caps be 8
Step-by-step explanation:
The computation of the number of caps ordered in order to equal the cost is shown below:
Let us assume the number of cap be x
Now the equations are
17.75x + $30
15.50x + $48
Now equate these two equations
17.75x + $30 = 15.50x + $48
17.75x - 15.50x = $48 - $30
2.25x = $18
x = 8
Hence, the number of caps be 8

Find the value of x, y, and z. Round to the nearest tenth if needed.
Answer:
z^2 = y^2 + 6^2........equation 1
x^2 = y^2 + 24^2.....equation 2
30^2 = z^2 + x^2.......equation 3
put equation 1 and 2 in 3
30^2 = (y^2 +6^2) + (y^2 + 24^2)
900 = y^2 + 36 + y^2 + 576
900 = 2y^2 + 612
2y^2 = 900 - 612 = 288
divide both side by 2
y^2 = 144
find the square root of both sides
y = 12
recall
z^2 = y^2 + 6^2
z^2 = 144 + 36
z^2 = 180
z = 13.42
recall
x^2 = y^2 + 24^2
x^2 = 144 + 576
x^2 = 720
x = 26.83
Step-by-step explanation:
you get your 3 equations from the diagram above which as 3 triangles in it using pythagoras theorem
The values are:
x = 26.83
y = 12
z = 13.42
What is Pythagoras Theorem?The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
Given:
z² = y² + 6²........(1)
x² = y² + 24².....(2)
30² = z² + x²......(3)
Now, put the value from equation (1) and (2) in equation (3)
30² = ( y² + 6²) + (y² + 24²)
900 = y² + 36 + y² + 576
900 = 2y² + 612
2y² = 900 - 612
2y² = 288
y² = 144
y= √144
y = 12
So, z² = y² + 6²
z² = 144 + 36
z² = 180
z = 13.42
and, x² = y² + 24²
x² = 144 + 576
x² = 720
x = 26.83

In 1990, the value of a home is $170,000. Since then, its value has increased 5% per year.
What is the approximate value of the home in the year 1993?
Answer:
195.500
Step-by-step explanation:
5 percent of 170,000 is 8,500.
Since 3 years pass we're multiplying 8,500 by 3.
8,500
x 3
_____
25,500
Now we just add 170,000 + 25,500, and we get 195.500.

Miles has a train collection with 36 engines, 72 boxcars, and 18 cabooses. He wants to arrange the train cars in equal rows with only one type of train car in each row. How many can he put in each row? Mark 4 that apply.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Number of engines = 36
Number of car boxes = 72
Number of cabooses = 18
To areange in equal rows :
We need to obtain the greatest common factor :
Factors of :
36 : 2, 3, 4, 6, 9, 12, 18, 36
18 : 2, 3, 6, 9, 18
72 : 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The greatest common factor (GCF) is 18
Number that can be put in each row :
Cabooses :
18 / GCF = 18 / 18 1 row
Engines :
36 / GCF = 36 /18 = 2 rows
Box cars :
72 / GCF = 72 / 18 = 4 rows

Step-by-step explanation:
Solve the equation. 5t^3 +40t^2 = -80t
a. t= 0 and t= 4
b. t= -4 and t=0
c. t= -4 and t= 5
d. t= 4
Answer:
Option 'A' is true.
Step-by-step explanation:
Given the equation
[tex]5t^3\:+40t^2\:=\:-80t[/tex]
Add 80 to both sides
[tex]5t^3+40t^2+80t=-80t+80t[/tex]
Simplify
[tex]5t^3+40t^2+80t=0[/tex]
as 5t³ + 40t² + 80t = 5t (t + 4)²
5t (t + 4)² = 0
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
[tex]t=0[/tex] or [tex]t+4=0[/tex]
solving
[tex]t + 4 = 0[/tex]
subtract 4 from both sides
[tex]t+4-4=0-4[/tex]
Simplify
[tex]t=-4[/tex]
Therefore, the solution to the equation is:
[tex]t=0,\:t=-4[/tex]
Hence, option 'A' is true.

The equatorial diameter of a model of earth is 25.6 cm. What is the total surface area of the model
Answer:
[tex]2059.7\,\,cm^2[/tex]
Step-by-step explanation:
Diameter of a model of earth (D) = 25.6 cm
Radius of a model of earth (r) = [tex]\frac{D}{2}=\frac{25.6}{2}=12.8\,\,cm[/tex]
Earth has the shape of a sphere.
Total surface area of a sphere = [tex]4\pi r^2[/tex]
Put [tex]\pi=\frac{22}{7}\,,\,r=12.8\,\,cm[/tex]
So,
Total surface area of the model [tex]=4(\frac{22}{7})(12.8)^2=2059.7\,\,cm^2[/tex]

Answer:
21) There is a 0% chance of picking a 13 in a deck of cards. Impossible.
If there is a 0% chance that something will happen then it is impossible.
22) There is a 50% chance of picking a red card in a deck of cards. Equally likely.
If there is a 50% chance that something will happen, it is equally likely that it will happen.
23) There is an 80% chance of snow tomorrow. Likely or certain.
If there is an 80% chance of something happening, it means that the chances of that thing happening good and the event is likely to occur.
24) There is a 20% chance of rain tomorrow. Unlikely.
A low chance of 20% means that something is unlikely to occur.

Step-by-step explanation:
The shaded part of the curve with interval 0 <= x <= 1 is not the whole curve.
The point of the curve that is furthest to the left has x-value -5.
The point of the curve that is furthest to the right has x-value 3.
Hence the correct domain is -5 <= x <= 3.

5. A train travelled 720 km in 9 h. How far
would it travel in 11 h?
Answer:
The train would travel 880 km in 11 hours.
Step-by-step explanation:
Answer:
880 km
Step-by-step explanation:
To get from 9 to 11, we multiply 9 by 11/9, so the same must be done to 720 km to get the amount in 11 hours. 720 * 11/9 is equal to 880, so the train travels 880 km in 11 hours.
