A car dealership sells SUVs and passenger cars. For a recent year, 70 more SUVs were sold than passenger cars. If a total of 340 vehicles were sold, determine the number of each type of vehicle sold.
Answer:
135 cars; 205 SUVs
Step-by-step explanation:
Let c = number of cars sold.
Let s = number of SUVs sold.
s = c + 70
c + s = 340
Substitute s in the second equation with c + 70 and solve for c.
c + s = 340
c + c + 70 = 340
2c = 270
c = 135
s = c + 70
s = 135 + 70
s = 205
Answer: 135 cars; 205 SUVs
Two consecutive odd numbers total -20 find the smaller
Answer:
-9
Step-by-step explanation:
use an equation to solve this
consecutive means in succession, one after the other
since they're odd, both numbers have to be odd
let x be the first number
x+x+2=-20
+2 because if you only +1, one of the numbers would be even
2x+2=-20
-2. -2
2x=-22
x=-11
the smaller would be -9 since we are adding x and x+2 together

The scale of a map is 1 1/4 inches = 80 miles. On that map, two cities are 4 inches apart. What is the actual distance between the cities?
Answer: 256 miles
Step-by-step explanation:
if 1 1/4 inches = 80 miles, then 1/4 inch = 16 miles (there are five 1/4 in 1 1/4 inches, so 80/5 = 16)
there are sixteen 1/4 inches in 4 inches, and we know that each 1/4 inch is equal to 16 miles, so 16*16 = 256

The rate startfraction 450 pounds over 25 buckets endfraction describes the relationship between the number of buckets and the weight of the lobsters in the buckets. what is the weight of one bucket of lobsters?
15 pounds per bucket
18 pounds per bucket
20 pounds per bucket
25 pounds per bucket
Answer:
The answer is 18 pounds per bucket.
Understanding the ProblemIn this question, we are given the expression that relates the pounds of lobster to the number of buckets:
[tex]\displaystyle \frac{\text{450 pounds}}{\text{25 buckets}}[/tex]
This fraction is presented to give a proportion of pounds of lobster to the number of buckets these lobsters inhabit.
With this proportion, we are expected to assume that the rate will be equivalent across all of the buckets. Therefore, for each bucket, there will be an equal measurement of pounds of lobster.How to Solve the ProblemTo solve this problem, we need to know exactly how this rate will work.
A rate is the same thing as a fraction, percentage, or decimal. All of these forms are convertible between one another.
For instance, if we took 25%, we know that by dividing this by 100, we receive a decimal form (0.25) or a fractional form (1/4).
We can apply the same principle here.
SolvePart I - Set up the Rate
To solve, set up the rate:
[tex]\displaystyle \frac{450 \ \text{pounds}}{25 \ \text{buckets}}[/tex]
Part II - Find the GCF
Then, find the Greatest Common Factor (GCF) of the two digits:
25 — 1, 5, 25450 — 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450Check for common factors between the two trees:
1, 5, 25Since 25 is the greatest of the three factors, it is the GCF.
Part III - Apply the GCF
Divide both the numerator and the denominator by 25:
[tex]\displaystyle \frac{450}{25} = 18[/tex]
[tex]\displaystyle \frac{25}{25} = 1[/tex]
Part IV - Simplify
Set up the new fraction:
[tex]\displaystyle \frac{18}{1}[/tex]
Anything divided by 1 does not change:
[tex]\displaystyle \frac{18}{1} = 18[/tex]
Final ApplicationsSince we got 18 an answer, this means that there are 18 pounds of lobster per bucket.

How to find the root of x^2 -6x+8=0
Answer:
2,4
Step-by-step explanation:
This question is quite simple. First you need to find the factors of 8. Then you need to see which factors of positive 8 can add up to make -6. The factors are -4 and -2. Then expand. Now you have the equation x^2-4x-2x+8. Now group it.
(x^2-4x) +(-2x+8)
Then take out the X from the first group and the -2 from the second. We want the values in the brackets to be the same.
Now you have
x(x-4)-2(x-4)
Take the x and the -2x and make it a group. Now you have (x-4)(x-2)
Set x-4 equal to zero. x-4=0 Now solve it like a regular equation. Add four to both sides. Now you have x=4
Do the same thing with (x-2) and you get x=2
4 and 2 are your solutions
Answer:
x = 4 and x = 2
Step-by-step explanation:
The easiest way to find the roots is by converting the function into its factored form. This can be determined by asking the question:
What two numbers have a product 8 and a sum of -6?
These two values are -4 and -2.
-4 x -2 = 8
-4 + (-2) = -6
These two numbers are used in the factored form of the equation. You can prove the accuracy of the factored form by re-expanding it (multiply all the terms in the first parentheses by the terms in the second parentheses). The factored form looks like this:
(x - 4)(x - 2)
The roots are the values that make the expression equal 0. This can be done by setting each parentheses equal to 0 and solving for "x".
x - 4 = 0 x - 2 = 0
x = 4 x = 2
Therefore, the roots of the function x² - 6x + 8 are x = 4 and x = 2.
A triangle on a coordinate plane is translated according to the rule t–8, 4(x, y). which is another way to write this rule? (x, y) → (x 4, y – 8) (x, y) → (x – 4, y – 8) (x, y) → (x – 8, y 4) (x, y) → (x 8, y – 4)
The rule is a translation rule, and another way of writing the rule t -8, 4(x, y) is (x - 8, y + 4)
How to rewrite the transformation rule?The rule is given as:
t -8, 4(x, y)
The above rule means that:
A translation of 8 units right and 4 units up.
This is represented as:
(x - 8, y + 4)
Hence, another way of writing the rule t -8, 4(x, y) is (x - 8, y + 4)

Step-by-step explanation:
so, that means we want to find the time t (days) after which N = No/2
because "half-life" means the amount of time until half of the substance has disappeared (or transformed into something else).
so, we have
No/2 = No × e^(-0.1481×t)
No = 2× No × e^(-0.1481×t)
1 = 2×e^(‐0.1481×t)
1/2 = 0.5 = e^(-0.1481×t)
ln(0.5) = -0.1481×t
t = ln(0.5)/-0.1481 = 4.680264555... ≈ 4.7 days

Find the lateral area and the surface area of the composite solid. Round your answers to the nearest hundredth.
The lateral area is about ____
square inches
The surface area is about ___
square inches
The surface area of the solid will be A=327.5 square inches and the lateral surface area will be A= 377.5 square inches.
What is the area?The space occupied by any figure in the two-dimensional space is called an area. The area can be rectangular circular triangular types.
Here we have the figure made up by the two pyramids and one rectangular box. So we will find the surface area of the pyramid then the rectangular box and again the pyramid and will add all of them.
The Lateral surface area will be calculated as:-
A=2W√(w÷2)²+(h)²+w²
A=2x5√(5÷2)²+(3)²+5x5
A=152.5 +25
A=177.5 square inch
Area of lower pyramid= (1÷2)xbxh+w²
A=(1÷2)x5x7.5 + 25 =75+25= 100
Area of the rectangular box= 4(w²)=4(5x5)=100
So total lateral surface area will be =100+100+177.5=377.5 square inch
(2)The surface area will be calculated as:-
A=2W√(w÷2)²+(h)²
A=2x5√(5÷2)²+(3)²
A=152.5 square inches
Area of lower pyramid= (1÷2)xbxh
A=(1÷2)x5x7.5 =75 square inches
Area of the rectangular box= 4(w²)=4(5x5)=100
So total surface area will be =100+75+152.5=327.5 square inch
Hence the surface area of the solid will be A=327.5 square inches and the lateral surface area will be A= 377.5 square inches.

The correct option is B.
What is ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given,
Diameter of dime = 17.91mm
Diameter of human hair = 6.0×10⁻²mm
Ratio of diameter of dime to diameter of human hair = 17.91/6.0×10⁻²
