What number is 45% of 360?
Answer:
6 or 60. 45 is in it. Best I can explain
Answer:
162
Step-by-step explanation:
step 1. our output value is 360
step 2. we represent the unknown value with x
step3. from step 1 above, 360= 100%
step 4. similarity, x=45%
step 5. this result in a pair of simple equations
360=100%(1)
x=45%(2)
step 6. by dividing equation 1 and 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have
360/x = 45/100
x=162
therefore, 45% of 360 is 162

Pick The Biggest Answer? 0.046 0.059 0.01 0.098
Answer:
0.098
Step-by-step explanation:
It should be obvious that 0.098 is bigger than 0.046 and 0.059, so let's focus on 0.01
0.01 = 0.010 and again it should be obvious that it's smaller than 0.098
which of the following is not a factor of 4x^2 + 12x?
a) x + 3
b) x
c) 3x
d) 4
Answer:
C
Step-by-step explanation:
Let's try it
Take 4 out of the given function.
4(x^2 + 3x )
Now there is an ex on either side of the plus sign that can come out. If 4 can come out because a 4 is on either side of the plus sign, so can an ex.
4x(x + 3)
What have you found?
4 is a factor
x is a factor
x + 3 is a factor
What about 3x. Well it won't work evenly and a factor must divide evenly into the given function.
Find the slope that passes through the two points. (9,3) and (6,7)
Answer:
m=4/-3
Step-by-step explanation:
the equation for slope (m) when given two points is (y2-y1)/(x2-x1)
we are given the points (9,3) and (6,7)
we can label the points:
x1=9
y1=3
x2=6
y2=7
now substitute into the equation
m=(7-3)/(6-9)
subtract
m=4/-3
the slope is 4/-3

i need the help alot
Answer:
{-5/4, 8}
Step-by-step explanation:
We are given (4u + 5)(8 - u) = 0. Solve for u by setting each of the factors (4u + 5) and (8 - u) equal to zero and solving each of the resulting equations:
4u + 5 = 0 leads to u = -5/4, and
8 - u = 0 leads to u = 8.
The solutions are {-5/4, 8}

solve for x.cos(2x+9)=sin(x)
Answer:
x=27
Step-by-step explanation:
cos and sin are complementary angles. There theta or x add up to 90 degree. Using the formula.
cos x=sin y where x+y=90 let set up the equation.
[tex] \cos(2x + 9) = \sin(x) [/tex]
[tex]2x + 9 + x = 90[/tex]
[tex]3x + 9 = 90[/tex]
[tex]3x = 81[/tex]
[tex]x = 27[/tex]
To check our identity plug x in the top equation
[tex] \cos(2 \times 27 + 9)) = \sin(27) [/tex]
[tex] \cos(63) = \sin(27) [/tex]
they both equal about 0.45 so it is true.
x=27
Don Juan Fue a la ferretería a comprar una manguera para regar su jardín después de observar María eligió una que tiene la siguiente etiqueta 83 pies diámetro interior medio In cuántos metros de longitud tiene la manguera que compró don Juan
Don Juan fue a la ferreteria a comprar una manguera para regar su jardín. Después de observar varias, eligió la que tiene la siguiente etiqueta. 83 pies, Diamtero interior 1/2 in. a) ¿Cuántos metros de longitud tiene la manguera que compró Don Juan? b) ¿Cuántos centímetros de diámetro interior tiene la manguera?
Responder:
25,30 m
1,27 cm
Explicación paso a paso:
Estamos obligados a convertir la longitud de la manguera de pies a metros y el diámetro de pulgadas a centímetros:
Longitud de la manguera = 83 pies
Recordar ;
1 pie = 0.3048 m
83 pies = (83 * 0.3048) = 25.2984 m
= 25,30 m
El diámetro de la manguera = 1/2 pulgadas
1 pulgada = 2,54 centímetros
1/2 pulgada = (1/2 * 2.54) cm
1/2 pulgada = 1,27 cm
If I have 48 cards and and gave 10 to my friend and I have 38 left what what fractionbb be is my original number of cards
Question isn't well formatted :
If I have 48 cards and and gave 10 to my friend and I have 38 left. what fraction of original number of card do I have left.
Answer:
0.7917
Step-by-step explanation:
If I have 48 cards and and gave 10 to my friend and I have 38 left what what fractionbb be is my original number of cards
Given that :
Total number of cards = 48
Number given to friend = 10
Number of cards left = 48 - 10 = 38
Number of cards left / original number of cards
38 / 48
= 0.7917

This diagram is not really to scale much but that would be the math you'd use to find angle m
I need help I need it ASAP!!
Answer:
50º
Step-by-step explanation:
A triangles angles = 180º
Angle A = 40º
Angle C = 90º (this is a right triangle)
40º + 90º = 130º
180º - 130 º = 50º
Find the missing dimension of the triangle. A triangle with base labeled b, height labeled 6 feet, and height labeled 14 square feet.
The base of the triangle is 4.67 feet.
Given data:
To clarify, if a triangle with a base labeled b, a height of 6 feet, and an area of 14 square feet, the missing dimension can be determined as:
The formula to calculate the area of a triangle is:
Area = (base * height) / 2
Given that the area is 14 square feet and the height is 6 feet, rearrange the formula to solve for the base:
14 = (b * 6) / 2
Multiplying both sides of the equation by 2:
28 = b * 6
Dividing both sides of the equation by 6:
b = 28 / 6
Simplifying the fraction:
b = 14 / 3
Hence, the missing dimension, the base of the triangle, is 14/3 feet or approximately 4.67 feet.

On Monday Katie spent 2 1/6 hours studying. On Tuesday she spent another 4 7/9 hours studying. What is the combined length of time she spent studying?
Answer:6 17/18 hours
Step-by-step explanation:
We are informed that on Monday Katie spent 2 1/6 hours studying while onn Tuesday she spent another 4 7/9 hours studying.
The combined length of time she spent studying will be the addition of the numbers of hours spent studying on Monday and Tuesday. This will be:
= 2 1/6 + 4 7/9
= 2 3/18 + 4 14/18
= 6 17/18
She used a total of 6 17/18 hours studying
