Glenn has a garden that is shaped like a rectangle.
The perimeter of his garden is 70 1/2 feet.
The length of the garden is 24 3/4 feet.
What is the width of the garden?
21 ft o 11ft o 10 ½ ft o 45 ¾ ft
Answer:
Solution given:
The length of the garden[l] = 24 3/4 =99/4feet.
breadth or width [b]=b
perimeter of his garden = 70 1/2=141/2 feet.
2[l+b]=141/2ft
99/4+b=141/4
b=141/4-99/4
b=21/2
b=10 ½ft
So the width of the garden is 10 ½ft.

JUAN DECIDE PINTAR LAS PAREDES DE SU CASA UN TOTAL DE 200 METROS LOS DOS PRIMEROS DIAS PINTO 33 METROS CADA DIA AL TERCER DIA COMO TENIA PRACTICA PINTO 96 METROS CUANTOS METROS LE QUEDAN PARA PINTAR
Answer:
38 metros
Step-by-step explanation:
Número total de metros que Juan quiere pintar su casa = 200 m
Durante los primeros 2 días, pintó = 33 m todos los días
Por lo tanto, el número total de metros que pintó = 33 m × 2 = 66 m
Al tercer día, practica la pintura = 96 m
El número de metros que quedan por pintar se calcula como:
200m - (66m + 96m)
Los 200m - 162m
= 38m

The sum of David and Jacobs age is 39. Two years ago David was four times Jacobs age. How old are three now?
Answer:
David is 30
Jacob is 9
Step-by-step explanation:
The sum of David and Jacobs age is 39
d + j = 39
d = 39 - j
----------------------
Two years ago David was four times Jacobs age
(d - 2) = 4(j - 2)
d - 2 = 4j - 8
d = 4j - 6
---------------------
Set the equations equal
4j - 6 = 39 - j
5j = 45
j = 9
d = 4(9) - 6
d = 30

common difference (d) = 11-7 = 4
Recursive rule: A(n) = A(n-1) + d = A(n-1) + 4
Explicit rule: A(n) = A(1) + d * (n-1) = A(1) + 4 *(n-1) = 7 + 4 * (n-1) = 4n + 3
15th term: A(15) = 4 * 15 + 3 = 63
A telephone call costs c cents for the first 3 minutes and m cents for each additional minute. Which expression represents the cost, in cents, of a 6-minute call?
Answer: [tex]c+3m[/tex]
Step-by-step explanation:
Given
A telephone call costs c cents for first 3 minutes and m cents for each additional minute.
Any call beyond 3 minutes costs
[tex]\Rightarrow c+mt[/tex]
where t is the minutes spent beyond 3 minutes
For 6 minutes , t is 3
thus, it can be written
[tex]\Rightarrow c+3m[/tex]
Find X using the image.
9514 1404 393
Answer:
x = 2
Step-by-step explanation:
The square of the tangent is equal to the product of the secant lengths to the near and far circle intersections.
(x +4)² = (2x -1)(2x -1 +9)
0 = (2x -1)(2x +8) -(x +4)² = (4x² +14x -8) -(x² +8x +16)
0 = 3x² +6x -24 = 3(x² +2x -8) = 3(x +4)(x -2)
This has solutions x = -4 and x = 2. Only the latter works in this geometry.
x = 2

A can of nuts weighs 1 pound, 1 ounce. The empty can weighs 3 ounces. If you pour out half the nuts into a bowl, how many ounces of nuts are in the bowl?
Answer:
7 ounces
Step-by-step explanation:
There are 16 ounces in one pound, so there are 17 ounces for the can of nuts.
Since the empty can weighs 3 ounces, you can subtract 17-3, which equals 14, to get the weight of the nuts alone.
Then, you divide 14 by 2, and you get 7.
yo can someone tell me if this scatter plot is linear or non linear plz
Answer:
it should be linear
Step-by-step explanation:
if its linear u can draw a straight line through most of the points

So lets go voer what we know:
There are 6 pieces of ribbon.
Each piece of ribbon is 1 yard long.
We need 1/3 of each ribbon(1/3 yard).
To find this, lets take our 6 pieces of ribbbon, and break them into 3 seperate pieces.
This is because we need ribbons that are 1/3 of a yard. 3 ribbons would make up a single yard.
So:
The 6 yards of ribbon x 3 ribbons that make up 1 yard
6*3
=

Answer:
2rootover5
Step-by-step explanation:
just use pythagoraus theorem
Answer:
x ≈ 4.5
Step-by-step explanation:
First, use the Pythagorean theorem to find the missing variable with side 8 and hypotenuse 10.
a² + b² = c²
a² + 8² = 10²
Square the variables
a² + 64 = 100
Subtract 64 from both sides.
a² = 36
Take the square root of both sides.
a = 6.
Now we can find the other triangle and we now know that one side is 4 and the hypotenuse is 6.
a² + b² = c²
x² + 4² = 6²
Square the variables.
x² + 16 = 36
Subtract 16 from both sides.
x² = 20
Square root. (refresh if you don't see this part.)
[tex]x=\sqrt{20}\\\text{Factor out a 2.}\\x=2\sqrt{5}[/tex]
Converted to decimal to the nearest tenth, the answer is
x = 4.5.
Now let's prove it.
[tex]a^2+b^2=c^2\\\text{Substitute variables.}\\(2\sqrt{5})^2+4^2=6^2\\\text{Factor the 2 in.}\\(\sqrt{20})^2+4^2=6^2\\\text{Square the variables.}\\20+16=36\\\text{Add.}\\36=36[/tex]

Answer:
66 is equal to K
Step-by-step explanation:
if 4 times 6 equal 24
then 11 time 6 equals 66
in this case, the scale factor is 6.
Have a wonderful day!
Answer:
K = 66
Step-by-step explanation:
[tex]\frac{k}{24} = \frac{11}{4}[/tex]
when taking a look at this, first try to see if you can solve the denominator.
24 to 4 equals 6 meaning you divide k by 6 will be equal to 11
Then 11 x 6 = 66!!
