Answer:
88 cars132 trucksStep-by-step explanation:
This is a ratio problem, the ratio of cars to trucks
for every 4 cars, there are 6 trucks
represented as a ratio we have 4:6
1. how many of them are cars
applying the part to whole strategy we have
4+6 = 10
let cars be x
[tex]\frac{4}{10}= \frac{x}{220} \\\\x= \frac{220*4}{10} \\\\x= 880/10\\\\x= 88 cars[/tex]
2. how many of them are trucks?
let trucks be y
[tex]\frac{6}{10}= \frac{y}{220} \\\\x= \frac{220*6}{10} \\\\y= 1320/10 \\\\y= 132 trucks[/tex]
1) 3(3x - 4) = -2(1 – 4x)
Answer:

Consider this equation 2,900 = 250 + 132.5T. In this situation, what would the solution
to this equation tell us?
Answer:
T = 20Step-by-step explanation:
Given the equation 2,900 = 250 + 132.5T, to get the solution of the equation, we will find the value of T as shown;
From 2,900 = 250 + 132.5T
subtract 250 from both sides;
2,900- 250 = 250 + 132.5T-250
2,650 = 132.5T
Divide both sides by 132.5
132.5T/132.5 = 2650/132.5
T = 20
Hence the solution to the equation tells us that the value of T is 20

Step-by-step explanation:
45+4x=6x+5
45=2x+5
40=2x
20=x
x=20
Answer:
x = 20
Step-by-step explanation:
45 + 4x = 6x + 5
45 - 5 =6x - 4x
40 = 2x
x = 40/2
x = 20
Check:
45 + 4*20 = 6*20 + 5
45 + 80 = 120 + 5 = 125
Is there a dilation that maps shape II onto shape I? If so, what is the scale factor and is it an enlargement or a reduction?
Shape II was dilated by a scale factor of 1/3 to form shape I. This is a reduction since the scale factor is less than 1.
What is transformation?Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, reflection, rotation and dilation.
Shape II was dilated by a scale factor of 1/3 to form shape I. This is a reduction since the scale factor is less than 1.

#SPJ1
Answer: A dilation will map shape I onto shape II. The bottom left coordinate of shape I is (1, 1) and the bottom left coordinate of shape II is (3, 3). So, to get the corresponding coordinates of shape II, multiply the coordinates of shape I by 3. This is true for every set of coordinates. So, the scale factor is 3. Because the scale factor is 3, which is greater than 1, the dilation is an enlargement.
J/6 -9=5/6
Can u give me a step to step answer
Answer:
j = 59
Step-by-step explanation:
since you are solving for j, you want to get it by itself
you can start out by multiplying both sides of the equation by 6 to get rid of the fractions
[tex](6)(\frac{j}{6}-9)=\frac{5}{6}(6)[/tex]
distribute the 6
[tex]j-54=5[/tex]
add 54 to both sides
[tex]j-54+54=5+54[/tex]
[tex]j=59[/tex]

Which is not a pair of congruent angles in the diagram below?
A. Angles BDA and DBC
B. Angles ABD and BAD
C. Angles ABD and BDC
D. Angles BCD and BAD
Answer:
B. Angles ABD and BAD
Step-by-step explanation:
The way that you tell which angles are congruent, are based on the angle marks. Angle A and C are congruent because they both contain 3 of the congruency marks, meaning they would equal the same degree. The answer is B because starting with angle BDA, B is your starting point, whereas D is the angle and A is the point you end on. With angle BAD, you start at point B and end at D, making angle A the one you're looking at. Because angle A contains 3 congruency marks, while angle B only contains one, this makes the two angles NOT congruent. Hope this helps. :)
Answer:
angles ABD and BAD
Step-by-step explanation:
The congruent angles match in the number of angle markings on the diagram.
The volume of the cell phone is 75 cubic centimeters. Write and solve an equation to find the height of the cell phone. Round your answer to the nearest tenth
Answer:
Equation: [tex]Height = \frac{75}{Area}[/tex]
Step-by-step explanation:
The question is incomplete as the dimension of the phone was not given.
However, the following explanation will guide you
Given
[tex]Volume = 75\ in^3[/tex]
Required
Determine the Height
Volume is calculated as thus;
[tex]Volume = Area * Height[/tex]
Substitute 75 for Volume
[tex]75= Area * Height[/tex]
Divide through by Area
[tex]Height = \frac{75}{Area}[/tex]
The above represent the equation to solve for Height
To solve for height, we need the dimension of the phone or the area.
Take for instance; the length and width of the phone is 5 by 5 inches;
The height would be:
[tex]Height = \frac{75}{5 * 5}[/tex]
[tex]Height = \frac{75}{25}[/tex]
[tex]Height = 3\ inches[/tex]

The Hartman family is saving $400 monthly for Ronald's college education. The family anticipates they will need to
contribute $20,000 toward his first year of college, which is in 4 years. Which best explains whether the family will
have enough money in 4 years?
The family will not have enough money. They will have saved only $16,000.
O The family will not have enough money. They will have saved only $19,200.
The family will likely have enough money. They will have saved $16,000 and have accumulated interest.
O The family will likely have enough money. They will have saved $19,200 and have accumulated interest.
Answer:
The family will not have enough money. They will have saved only 19,200
Step-by-step explanation:
The family will not have enough money. They will have saved only $19,200 is the best statement.
What is interest?
" Interest is defined as the amount of money which one has to pay while borrowing and charged while lending money."
According to the question,
Amount saved per month by Hartman family = $400
Amount need to pay fees after 4 years = $20,000
Total amount saved in 4years = 400 × 12 ×4
= $19200
Difference in amount needed = 20,000 - 19,200
= $800
Here it is not given that Hartman family has saved money in any bank.
Neither rate of interest is mentioned.
Hence, we conclude that the family will not have enough money. They will have saved only $19,200 is the best statement.

4-7x=1-6x can someone please solve and show the work :)
Answer:
x = 3
Step-by-step explanation:
Simplifying
4 + -7x = 1 + -6x
Solving
4 + -7x = 1 + -6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6x' to each side of the equation.
4 + -7x + 6x = 1 + -6x + 6x
Combine like terms: -7x + 6x = -1x
4 + -1x = 1 + -6x + 6x
Combine like terms: -6x + 6x = 0
4 + -1x = 1 + 0
4 + -1x = 1
Add '-4' to each side of the equation.
4 + -4 + -1x = 1 + -4
Combine like terms: 4 + -4 = 0
0 + -1x = 1 + -4
-1x = 1 + -4
Combine like terms: 1 + -4 = -3
-1x = -3
Divide each side by '-1'.
x = 3
Simplifying
x = 3
