The ratio of the lengths of 3 squares of different sizes is 2:4:7. If the length of the biggest
square is 10 cm longer than the smallest square, find the perimeter of the smallest square.
9514 1404 393
Answer:
16
Step-by-step explanation:
The largest square is 7-2 = 5 ratio units larger than the smaller square. Hence, each ratio unit stands for (10 cm)/5 = 2 cm. The side length of the smaller square is 2(2 cm) = 4 cm. The perimeter is 4 times that: 16 cm.
The perimeter of the smallest square is 16 cm.
What is the probability of choosing a king of hearts or a queen of spades from a deck of cards? Type your answer as a fraction
Answer:
[tex]Pr = \frac{1}{26}[/tex]
Step-by-step explanation:
Given
In a deck of card, we have:
[tex]Cards = 52[/tex]
[tex]King[Heart] = 1[/tex]
[tex]Queen[Spade] = 1[/tex]
Required
The probability of obtaining a king of heart or a queen of spade.
The probability of king of heart is:
[tex]P(King[Heart]) = \frac{n(King[Heart])}{Cards}[/tex]
[tex]P(King[Heart]) = \frac{1}{52}[/tex]
The probability of queen of spade is:
[tex]P(Queen[Spade]) = \frac{n(Queen[Spade])}{Cards}[/tex]
[tex]P(Queen[Spade]) = \frac{1}{52}[/tex]
The required probability of obtaining a king of heart or a queen of spade. is:
[tex]Pr = P(King[Heart]) + P(Queen[Spade])[/tex]
[tex]Pr = \frac{1}{52}+ \frac{1}{52}[/tex]
Take LCM
[tex]Pr = \frac{1+1}{52}[/tex]
[tex]Pr = \frac{2}{52}[/tex]
Simplify
[tex]Pr = \frac{1}{26}[/tex]
Eloise can fertilize her lawn in t hr. What is the rate at which she does this job?
Answer:
1 / t
Step-by-step explanation:
The rate at which a job, chore or a certain task is executed is expressed as the reciprocal of the time taken to complete such task. That is ;
Rate = 1 / time taken
From the scenario above, the time taken = t hours
Then the rate at which work is done can be expressed as :

Answer:
It is correct for 5. Incorrect for 6. Lastly, correct for 7.
Answer:
yes
no
yes
Step-by-step explanation:
you plug in the 3 into the x, because x=3 so therefore 3+5>7 which becomes 8>7. Is 8 more than 7? yes! so its true. For the next, 7>12, thats not true. And for the last one, 10-7<5, so 3<5, which is true.
If f(x) = x - 1 and g(x) = x3, what is (gºf)(8)?
Answer:
343
Step-by-step explanation:
f(x) = x - 1 and g(x) = x^3
g(f(8))
First find f(8) = f(8-1) = 7
Then find g(7) = 7^3 = 343
g(f(8) = 343
Answer:
I will assume that you meant to type (g o f)(8).
First we find f(8).
f(8) = 8 - 1 or 7.
We now find g(f(8)), which means g(7).
g(7) = 7^3 or 343
(g o f)(8) = 343:

Answer:
P = 10π + 30 ≈ 61.4
Step-by-step explanation:
Perimeter = s1 + s2 + s3 + s4
= πd/2 + 15 + πd/2 + 15 = 2 (5π + 15) = 10π + 30 ≈ 61.4
Final Question!!!! College Math! I also did half of it!
Answer:
15π/4
9π /4
Step-by-step explanation:
[tex]5 \int\limits^4_1 {f(x)} \, dx[/tex] = 5 ((-π/4)+ π) = 5 (π-π/4) = 5(3π/4) = 15π/4
[tex]5 \int\limits^6_1 {|f(x)|} \, dx[/tex] = 5(π/4 + 2π) = 5(9π /4) = 45π/4
A rotating lawn spinner sprays water on a circular area of grass, The radius of the circular area is 8ft. What measurement is closest to the area.
Answer:
Area of circle = 201.09 ft²
Step-by-step explanation:
Given the following data;
Radius, r = 8 ft
To find the area of the circular area;
Area of circle = πr²
Area of circle = 3.142 * 8²
Area of circle = 3.142 * 64
Area of circle = 201.09 ft²
Therefore, the measurement which is closest to the area is 201.09 square feet.
Brand A and brand B of frozen green beans both list a weight of 32 ounces on their bags. Because of variability in the manufacturing process, the bags often contain slightly more, or less, than 32 ounces of green beans.

Step-by-step explanation:
You can plug in the points into the function to test them.

3(0) - 4(-5) - 8 = 12
20 - 8 = 12

Find the slopes of the lines containing the following. (If an answer is undefined, enter UNDEFINED.)
a)
b)
c)
d)
e)
f)
Answer:
Step-by-step explanation:
a)
m = y2-y1 / x2-x1
P1 = (3,-4) as (x1,y1)
P2= (5,6) as (x2,y2)
m = 6-(-4) / 5 - 3)
m = 6+4 / 2
m = 10 / 2
m = 5
b)
m = y2-y1 / x2-x1
P1 = (5,-3) as (x1,y1)
P2= (5,6) as (x2,y2)
m= 6-(-3) / 5-5
m = 6+3 / 0 ( the world blows up when you divide by zero :0 undefined )
c)
m = y2-y1 / x2-x1
P1 = (1,-1) as (x1,y1)
P2= (8,-8) as (x2,y2)
m = -8-(-1) / 8-1
m = -8+1 / 7
m = -7 / 7
m = -1
d)
m = y2-y1 / x2-x1
P1 = (-2.8,2) as (x1,y1)
P2= (-1.2,2) as (x2,y2)
m = 2-2 / a number 0 because the numerator is 0 and there is a number in the denominator
e)
m = y2-y1 / x2-x1
P1 = (c,d) as (x1,y1)
P2= (e,f) as (x2,y2)
m = f-d / e-c that's all you can do until we're given those variables
f)
m = y2-y1 / x2-x1
P1 = (0,c) as (x1,y1)
P2= (d,0) as (x2,y2)
m = 0-c / d-0
m = -c /d

If p and q vary inversely and p is 2 when q is 21, determine q when p is equal to 6.
Answer:
[tex]q = 7[/tex]
Step-by-step explanation:
Given
[tex]p\ \alpha\ \frac{1}{q}[/tex] --- inverse variation
[tex]p =2; q = 21[/tex]
Required
Find q when [tex]p = 6[/tex]
[tex]p\ \alpha\ \frac{1}{q}[/tex]
This becomes
[tex]p = \frac{k}{q}[/tex]
Where k is the constant of variation.
Make k the subject
[tex]k = p * q[/tex]
Substitute [tex]p =2; q = 21[/tex]
[tex]k = 2 * 21[/tex]
[tex]k =42[/tex]
When [tex]p = 6[/tex], we have:
[tex]p = \frac{k}{q}[/tex]
[tex]6 = \frac{42}{q}\\[/tex]
Make q the subject
[tex]q = \frac{42}{6}[/tex]
[tex]q = 7[/tex]

Answer:
Difference in large and small numbers, higher or smaller value.
Answer:
The range is the difference between the largest and smallest numbers. If you are talking in math.
Example 1: 1, 2, 5, 6, 7
so the smallest number is 1 and the largest number is 7 so 7-1=6
The range is 6.
Example 2: 16, 19, 10, 17, 42
now we have a data set that is not in order. First step is to order them:
10, 16, 17, 19, 42
Next take the smallest and largest number and subtract them: 42-10=32
The range is 32.
