Step-by-step explanation:
If 35 = 5x, then 9 - 7x = ?
Answer:
Since 35/7=5, 5x7=35.
So x=7.
9-7=5
5x=35
Find the missing variable if 13-4x=1-x
Answer:
X=4
Step-by-step explanation:
Move the variable to the left side
13-4x+x=1
Subtract 13 on both sides
13-4x+x=1
-13 -13
Collect the like terms
-3x= -12
Divide both side4s by -3
-3x/-3= -12/-3
Answer:
X=4
If there are 5380 feet in a mile Express 4000 get In kilometers
please show how you go it
Answer:
ok first there is a problem here there are actually 5280 NOT 5380 feet in a mile. Is this a typo or are you to assume a different length of a mile?
I will stick with the real value of 5280...
5280 feet/ mile * 0.62137119 miles/ km = 3280 f/km
3280 f/km / 4000 feet = .82 km
Step-by-step explanation:
The first term of an A.P. is unity and the common difference is 4, which of the following will be a term of this A.P. (a ) 4551 (b ) 10091 ( c ) 7881 ( d ) 13531
Answer:
c
Step-by-step explanation:
first term=1
common d=4
nth term=a+(n-1)d
7881=1+(n-1)4
7881=1+4n-4
7884=4n
n=1971
Starting with n = 0, the n-th term in the sequence is
4n + 1
so any number in the sequence must have a remainder of 1 when divided by 4.
We have
4551 = 1137×4 + 3
10091 = 2522×4 + 3
7881 = 1970×4 + 1
13351 = 3382×4 + 3

Maggie needs to spend at least six hours each week practicing the piano. She already practiced 3 1/4 hours this week. She wants to split the remaining practice time evenly between the last two days of the week. Which inequality best determines the minimum number of hours she needs to practice on each of the two days.
Answer:
Let X equal the remaining time she needs to practice.
You would have 2x
The combined total needs to be 6 hours or greater.
You need to add the amount she already practiced to 2x.
Now you have: three and one fourth + 2x
This needs to be greater than or equal to 6.
Ans:- three and one fourth + 2x ≥ 6
Does the graph represent a function? Khan Academy
Answer:
yes
Step-by-step explanation:
try using a vertical line, if you move the vertical line across the graph and the line touches the graph only at one point, than it means it is a function
Answer:
This graph represents a function
Step-by-step explanation:
By its definition, a function is a relation or a correlation between two sets (groups) of values where every input corresponds to only one output. What this means is that every input in a function can only have one output. This characteristic results in a unique property in the graph of a function, that is, the verticle line test. The verticle line test states that when one draws a line through the graph of a function, the line can only intersect the graph in exactly one place in the function. If the line intersects the graph in more than one place, then the graph does not represent a function. In the given situation, any verticle line drawn on the graph only intersects the graph in one place, thus the graph represents a function.

The table shows the estimated number of deer living in a forest over a five-year period. Are the data best represented by a linear, exponential, or quadratic model? Write an equation to model the data.
A. exponential; y = 89 • 0.62x
B. linear; y = 0.62x + 89
C. quadratic; y = 0.62x2 + 89
D. quadratic; y = 89x2 + 0.62
Answer:
A. exponential; y = 89 • 0.62x
Step-by-step explanation:
exponential; y = 89 • 0.62^x
Answer:
Option B exponential y = 89 · 0.62x
Step-by-step explanation:
The table shows the estimated number of deer living in a forest over a five year period.
Year Number of deers
0 89
1 55
2 34
3 21
4 13
Now we have to find the model representing this situation. Difference in number of deer, in the forest.
We can see there is a common ratio between each successive term r = = 0.618
r = = 0.618
so it can be represented by an exponential model.
Find all of the missing angles - a, b, c, and d.
Answer:
a. 65 degree
B. 25 degree
c. 25 degree
d. 75 degree
Step-by-step explanation:
shown in photo.
Mark me brain list if it help you
Answer:
a = 65°
b = 25°
c = 25°
d = 75°
Step-by-step explanation:
60 + a + 55 = 180 (Angles of a straight line)
a + 115 = 180
a = 180 - 115
a = 65°
a + b + 90 = 180 (Interior angles of a triangle add up to 180°)
65 + b + 90 = 180
b + 155 = 180
b = 180 - 155
b = 25°
b = c (Vertically opposite angles are equal)
c = 25°
d + 15 = 90 (Complementary angles)
d = 90 - 15
d = 75°

35 is 26% of what number?
Answer:
134.61 is the answer . hope This helps
Answer:
The answer is 134.61
Step-by-step explanation:
We have, 26% × x = 35
Or, 26/100 × x = 35
We have: x = 35 × 100/26
35×100 = 3,500
3,500 ÷ 26 = 134.61
x = 134.61
If you use a calculator, simply put 35×100÷26, which will give you the answer.

x = 8
Step-by-step explanation:
Hi there!
[tex]\displaystyle\frac{9}{24}=\frac{3}{x}[/tex]
9/24 can be simplified by dividing both the numerator and denominator by 3:
[tex]\displaystyle\frac{9\div3}{24\div3}=\frac{3}{x}\\\\\\\frac{3}{8} =\frac{3}{x} \\\\\\x=8[/tex]
Therefore, x is 8.

(1+sin2A+cos2A)^2=4cos^2A(1+sin2A)
Answer:
(1+sin2A+cos2A) ^2=4cos^2A(1+sin2A)
Step-by-step explanation:
Here,
L.H.S=(1+sin2A+cos2A)^2
=(1+2sinAcosA+2cos^2A-1)^2
=(2sinAcosA+2cos^2A)^2
={2cosA(sinA+cosA)}^2
=4cos^2A(sinA+cosA)^2
=4cos^2A(sin^2A+2sinA.cosA+cos^2A)
=4cos^2A(sin^2A+cos^A+2sinAcosA)
=4cos^2A(1+sin2A)
=R.H.S
Hence,L.H.S=R.H.S.
(1+sin2A+cos2A)^2=4cos^2A(1+sin2A).
proved.
the legs of a right triangle are 75 and 100. what is the length of the hypotenuse
Hey there! I'm happy to help!
To find the hypotenuse of a right triangle given two legs, you use the Pythagorean Theorem.
a²+b²=c², where a and b are the legs and c is the hypotenuse.
Let's plug our values into the equation and solve for c (our hypotenuse).
75²+100²=c²
Square the numbers
5625+10000=c²
Add them
c²=25625
Square root both sides
c=125
