Answer:
2
Step-by-step explanation:
log 4 +log 25
Since these two equations have the same base and are being added, we can multiply the arguments
it would be: log 100
which is 2
Answer:
2
Step-by-step explanation: In logs, the opposite of addition is multiplication. Also, there needs to be only 1 log when you're condensing. So you'll multiply 4*25=100. And just plug in your calculator log(100) which is 2.

What is the range?
2 ,9 ,7 ,9 ,1 ,6
Answer:
8Step-by-step explanation:
The range is the difference between the highest and lowest values in a data set.
Highest value = 9Lowest value = 1Range = 9 - 1 = 8Answer:
8
Step-by-step explanation:
When finding the range, you have to subtract the smallest value from the biggest value,
2, 9, 7, 9, 1, 6
⇒ 1, 2, 6, 7, 9, 9
If we take a look at the set of numbers, we can see that 1 is the smallest value and 9 is the biggest,
Now that know that we need to subtract,
9 - 1
= 8
Therefore the range of this set of numbers is 8.

circle theorem - find p
Answer:
C
Step-by-step explanation:
the angle in a semicircle = 90° , that is the 3rd angle in the triangle.
the sum of the 3 angles in a triangle = 180° , then
p + 90° + 42° = 180°
p + 132° = 180° ( subtract 142° from both sides )
p = 48°

Find the diameter of the circle with the given circumference. Use 3.14 for pi . C=18 cm
Answer:
[tex]d=\frac{18}{\pi }[/tex]
Step-by-step explanation:
We work our way backward to find the diameter.
Circumference of a Circle Formula:
[tex]C=2\pi r[/tex]
r is radius , 2*radius = diameter.
Given information: C=18 cm , pi=3.14.
[tex]C=2\pi r\\18=2\pi r\\[/tex]
Get r by itself.
[tex]r=18/2\pi\\r=9/\pi[/tex]
r≈2.864788976
2*r=d
[tex]2*9/\pi =diameter\\d=\frac{18}{\pi }[/tex]

What is an equation of the line that passes through the points (-3,8) and (-2,3)?
Answer:
y = -5x + 7
Step-by-step explanation:
You want to find the equation for a line that passes through the two points:
(-3,8) and (-2,3)First of all, remember what the equation of a line is:
y = mx+bWhere:
m is the slope, andb is the y-interceptFirst, let's find what m is, the slope of the line...
The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.
For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:
[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
So what we need now are the two points you gave that the line passes through. Let's call the first point you gave, (-3,8), point #1, so the x and y numbers given will be called x₁ and y₁. Or x₁ = -3 and y₁ = 8.
Also, let's call the second point you gave, (-2,3), point #2, so the x and y numbers here will be called x₂ and y₂. Or, x₂ = -2 and y₂ = 3.
Now, just plug the numbers into the formula for m above, like this:
[tex]m=\frac{3-8}{-2--3}[/tex]
or...
[tex]m=\frac{-5}{1}[/tex]
or...
[tex]m=-5[/tex]
So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:
[tex]y=-5x+b[/tex]
Now, what about b, the y-intercept?
To find b, think about what your (x,y) points mean:
(-3,8). When x of the line is -3, y of the line must be 8.(-2,3). When x of the line is -2, y of the line must be 3.Because you said the line passes through each one of these two points, right?
Now, look at our line's equation so far: y=-5x+b. b is what we want, the -5 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the two points (-3,8) and (-2,3).
So, why not plug in for x and y from one of our (x,y) points that we know the line passes through? This will allow us to solve for b for the particular line that passes through the two points you gave!
You can use either (x,y) point you want..the answer will be the same:
(-3,8). y=mx+b or 8=-5 × -3+b, or solving for b: b=8-(-5)(-3). b=-7.(-2,3). y=mx+b or 3=-5 × -2+b, or solving for b: b=3-(-5)(-2). b=-7.See! In both cases we got the same value for b. And this completes our problem.
The equation of the line that passes through the points
(-3,8) and (-2,3)
is
y=-5x-7

Show that 7x + 1 is equivalence to 2(2x - 1) + 3(x + 1)
Answer with Step-by-step explanation:
2 ( 2x -1 ) + 3 ( x + 1 )
First, let us find the value of the above expression.
2 ( 2x -1 ) + 3 ( x + 1 )
4x - 2 + 3x + 3
Combine like terms
4x + 3x - 2 + 3
7x + 1
Therefore, it is clear that the given expression is equal to 7x + 1.
∴ 7x + 1 = 2 ( 2x -1 ) + 3 ( x + 1 )

An iced cake costs 10p more than a plain cake. Sarah bought two of each cake. They cost £1 altogether. What is the cost of an iced cake?
Answer:
55p
Step-by-step explanation:
iced cake = 10p more than a plain cake
iced cake = 10p + plain cake
iced cake and a plain cake together = £1
iced cake + plain cake = £1
if iced cake = 10p + plain cake, we can plug this into our second formula to get
(10p + plain cake) + plain cake = £1
10p + 2 * plain cake = £1 = 100p
subtract 10p from both sides to isolate the variable and its coefficient
2 * plain cake = 90p
divide both sides by 2 to isolate the variable
plain cake = 45p
iced cake = 10p + plain cake = 55p

Answer:
(a) 2.27 lb/$
(b) 0.10 mi/min
Step-by-step explanation:
(a)Pounds per dollar is found by dividing pounds by dollars:
(25 lb)/($11.00) ≈ 2.272727... lb/dollar
The digit in the thousandths place is less than 5, so that digit and all digits to its right are dropped when rounding to hundredths.
2.27 pounds per dollar
__
(b)Speed in miles per minute is found by dividing miles by minutes:
(6 mi)/(58 min) ≈ 0.103448... mi/min
Rounding to hundredths is done the same way as above.
0.10 miles per minute
_____
If the digit to the right of the place you're rounding to is 5 or more, then 1 is added in the place you're rounding to when digits to its right are dropped.
