Penguins can swim at a speed of up to 33 ft./s use dimensional analysis to convert the speed to miles per hour 1 mile equals 5280 feet
Answer:
v = 22.5 miles/hour
Step-by-step explanation:
It is given that,
The speed of Penguins is 33 ft/s.
We need to convert the speed to miles per hour.
We know that, 1 mile = 5280 feet
Speed,
[tex]v=33\ \dfrac{ft}{s}\\\\=33\times \dfrac{\dfrac{1}{5280}\ \text{miles}}{\dfrac{1}{3600}\ \text{hour}}\\\\=22.5\ \text{miles/hour}[/tex]
So, the speed of the Penguins is 22.5 miles/hour.

5x^2-22x+8=0
can you find the roots?
Step-by-step explanation:
Answer:
x = [tex]\frac{2}{5}[/tex], x = 4
Step-by-step explanation:
Given
5x² - 22x + 8 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 5 × 8 = + 40 and sum = - 22
The factors are - 20 and - 2
Use these factors to split the x- term
5x² - 20x - 2x + 8 = 0 ( factor the first/second and third/fourth terms )
5x(x - 4) - 2(x - 4) = 0 ← factor out (x - 4) from each term
(x - 4)(5x - 2) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
5x - 2 = 0 ⇒ 5x = 2 ⇒ x = [tex]\frac{2}{5}[/tex]

Choose the correct answer below.
A.
The two shops charge the same price for a 3-scoop sundae.
B.
The two shops charge the same price for a 2-scoop sundae.
C.
The two shops never charge the same price for sundaes with the same number of scoops.
D.
The two shops always charge the same price for sundaes with the same number of scoops.
Answer:
the answer is D.

this is because if you distribute 0.4 times 0.3 you get 0.12.
then you are left with 0.12+1 which means both shops charge the same price.

A car salesman gets paid $3,750 each month plus 8.5% commission on his total sales. This month he sold 5 cars for a total of $138,000. What are his monthly total earnings?
The car salesman total earnings if he sold 5 cars for a total of $138,000 is $15480.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.
Let y represent the total money the salesman earns for selling a total of $x sales. Hence:
y = 0.085x + 3750
If the salesman makes a total of $138000, hence:
y = 0.085(138000) + 3750
y = 15480
The car salesman total earnings if he sold 5 cars for a total of $138,000 is $15480.

how do you solve it and how do you explain?
Answer:
so the answer is 30
now to find the answer we just need to do this...
step 1: we need to simplify the equations from both sides.
[tex]\frac{-2}{5} x = -12[/tex]
then we multiply on both sides by [tex]\frac{5}{-2}[/tex]
[tex](\frac{5}{-2}) *(\frac{-2}{5}x )= (\frac{5}{-2} )*(-12)[/tex]
which equals x= 30

What is the equation in slope - intercept form of the line that has a slope of 0.25 and passes through the point (6, -8)?
Step-by-step explanation:
y-b=m(x-a)
y--8=1/4(x-6)
y+8=1/4(x-6)
4y+32=1(x-6)
4y+32=x-6
4y=x-38
y=1/4x-38/4
or -x+4y+38=0
or -×+4y= -38
Which of these expressions is equivalent to -2(x - 5)?
-2x + 5
-2x - 10
-2x + 10
-2x-5
Question 3
Mathematics
The equivalent expression is: -2x + 10. therefore the correct option is C.
What are equivalent expressions?Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.
From the distributive property;
-2(x - 5)
Then, multiply -2 and -5
-2 * x = -2x
-2 * -5 = 10
because two negatives make a positive
Therefore the answer would be -2x+10.
Hence,The equivalent expression is: -2x + 10. therefore the correct option is C.

Step-by-step explanation:
express the ratio 60cm to 20m
Answer:
3 cm : 1 cm
Step-by-step explanation:
1. 60 : 20
2. divide 10 on both sides = 6 : 2
3. divide by 2 on both sides = 3 : 1
4. 3 cm : 1 cm
I'm so sorry, I just read the ratio is 60 cm to 20 M
So edit:
convert both into a unit, we'll take m.
1 cm = 100 m
so 60 x 100 = 60000 m
= 60000 m : 20 m
= divide by 20 in both sides...
= 3000 m : 1 m
