Step-by-step explanation:
PLEASE HELP ME ASAP.
Step-by-step explanation:
anything whole or complete is designated as 100%.
what is x% of that whole ?
well, we need to multiply the whole with the same factor we need to multiply 100 with to get x.
100×f = x
f = x/100
whole × f = x% of the whole
so, when we are looking for 5%, what did that mean ?
it means that x = 5, and f = 5/100.
therefore, 5% of $13 is
13 × 5/100 = 65/100 = 0.65
so,
basic cost = $13
tax rate = 5%
tax amount = $0.65
and
basic cost = $13
tax amount = $0.65
total cost = 13 + 0.65 = $13.65
as 5/100 = 0.05
we have seen that the tax amount is simply $13×0.05
and when we add the tax amount to the basic cost, we need to add $13×1 (basic cost) to the $13×0.05 (tax amount), and we get as total
total cost = $13×(1+0.05) = $13×1.05 = $13.65
so, the decimal factor we can use directly without going through all the detail above is : 1.05

6. A road runs 1,200 feet from X to Y and then makes a right angle to Z, a distance of 500
ft. A new road is being built to connect X and Z. How much shorter wilt the new road
be?
Answer:
400 ftStep-by-step explanation:
Use the Pythagorean to find the distance XZ:
[tex]XZ=\sqrt{XY^2+YZ^2} =\sqrt{1200^2+500^2} =\sqrt{1690000} =1300[/tex]The difference of the distance is:
1200 + 500 - 1300 = 400 ft-35 + ( -31 ) + ( -39 )
Answer:-105
Step-by-step explanation:
Answer:
Ok so, let's break it down
Step-by-step explanation:
-35+(-31)
Let's ignore the parenthesis and the - symbol
35+31
That would equal 66, so now we add back the - symbol which will make it -66
So we already have -66, so now we have -66+(-39)
We do the same thing we did with -35+(-31)
So we have 66+39
That makes -105
So your answer is -105
Factor [tex]x^{4} -8x^{2} -9[/tex]
Answer:
[tex](x^2+1)(x-3)(x+3)[/tex]
Step-by-step explanation:
x^2^2 - 9x^2 + 1x^2 - 9
= x^2(x^2 - 9) + 1(x^2 - 9)
= (x^2 + 1)(x^2 - 9)
= (x^2 + 1)(x-3)(x+3) <- (This is due to the a^2-b^2 theorem)

Deion is making sandwiches for a picnic. He uses 2 slices of cheese to make each sandwich,
and he has a package of cheese with 24 slices. How many sandwiches can Deion make before
he runs out of cheese?
answer quickly please!
Answer:
12 sandwiches
Step-by-step explanation:
We know that Deion has 24 cheese slices, and uses 2 slices per sandwich, so in order to find how many sandwiches he can make, we can divide the total number of cheese slices by the number used to make a sandwich:
24 / 2 = 12
Therefore, Deion can make 12 sandwiches before he runs out of cheese.
Hope this helps :)

How do you write 7 1 \12 as a whole number
Answer: 7
Step-by-step explanation:
Write as a decimal
7 1/2 would be written as ~7.0833
Rounding a decimal to the nearest whole number
If you have a decimal that is greater than or equal to 5 in the tenths place then you round up. Ex: 5.8 would be rounded to 6, 1.5 would be rounded to 2.
If you have a decimal that is less than or equal to 4 in the tenths place then you round down. Ex: 5.1 would be rounded 5, 1.2 would be rounded to 1.
Since 0 is in the tenth’s place we round down to 7.

convert 150.55 decimal to binary
Answer:
10010110 . 100011₂
Step-by-step explanation:
A real number consists of two parts.
That is, ( 1 ) Integer part ( 2 ) fractional part
Let us take the given number as an example.
Here, 150 . 55 ← fractional part
↑
(integer part)
So, to make such a decimal number into a binary number you have to use a method like this.
First, you have to make the integer part a binary number.For that, you have to divide the integer part by 2 until it gets zero.Important thing is you have to write the remainders in each step.After that, you have to write the remainders from bottom to top.Now, let us consider the fractional part.To convert the fractional part into a binary number you have to multiply only the fractional part in each step by two.There you'll get an integer part before the fractional part. In this step, you have to write the integer part from top to bottom.Let us solve it now.
Integer part
2 |150
2 |75 - 0
2 | 37 - 1
2 | 18 - 1
2 | 9 - 0
2 | 4 - 1
2 | 2 - 0
2 | 1 - 0
0 - 1
∴ 150 ⇒ 10010110₂
Fractional part
| . 55 × 2
1 | . 10 × 2
0 | . 2 × 2
0 | . 4 × 2
0 | . 8 × 2
1 | . 6 × 2
1 | . 2
As this fractional part not getting the zero even we multiply by 2 continuously, we have to write an approximate value for this.
150.55 ⇒ 10010110 . 100011₂

How could the length of the shorter leg be determined without measuring it? What is its length?
Please use the Pythagorean Theorem and show me how you do it-- thanks.
Answer: 2.5 feet
Step-by-step explanation:
A 30-60-90 triangle is a special right triangle in which the sides all have a fixed relationship with each other. We only need to know one side to calculate the other two.
Make the side opposite the 30° angle x, then
The side opposite the 60° angle is x*√3The side opposite the 90° angle is 2xThe side opposite the right angle is 5ft, therefore:
2x = 5
x = 2.5ft, the side opposite the 30° angle
Then x*√3 is the third side:
(2.5)*(1.442) = 3.605 feet
Put the following equation of a line into slope-intercept form, simplifying all fractions. 5 x + 2 y = 10
Answer:
y = -5/2x + 5
Step-by-step explanation:
slope intercept form: y = mx + b
5x + 2y = 10 ------- subtract 5x on both sides
2y = -5x + 10 ------- divide 2 on both sides
y = -5/2x + 5

What is the equation, in slope-intercept form, of the line that passes through
the point (7, 2) and is parallel to y= -2x+1?
Find the slope of the parallel line
(7, 2) and is parallel to y= -2x+1?
When two lines are parallel, they have the same slope.
⇒ if the slope of the given line is = - 2
then the slope of the parallel line (m) = - 2
Determine the equation
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - 2 = - 2 (x - 7)
We can therefore write the equation in the slope-intercept form by making y the subject of the equation and expanding the bracket to simplify:
since y - 2 = - 2 (x - 7)
∴ y = - 2 x + 16Is this a right angle, obtuse triangle, Equilateral triangle or acute angle?

Answer:
this is acute angle.............. { because it's less than 90°}
What is the answer to this math question
Answer:
11
Step-by-step explanation:
1.80m + 0.6s = 12.00
[substitute the value of m into the equation]
1.80×(3) + 0.6s = 12
5.4 + 0.6s = 12
[make s the subject of the formula]
0.6s = 12 - 5.4
0.6s = 6.6
[divide both sides of the equation by 0.6]
0.6s / 0.6 = 6.6 / 0.6
s = 11
To prove that 11 is correct
[substitute the value of m and s into the equation]
1.80m + 0.6m = 12.00
1.80×(3) + 0.6×(11) = 12.00
5.4 + 6.6 = 12.00
12.00 = 12.00

A triangle is shown
What is x?
What is y?
What is z?
Answer:
x = 44
y = 136
z = 136
Step-by-step explanation:
The angles of a triangle have to add up to 180°
54 + 82 + x = 180
136 + x = 180
x = 44
We know that y and z are vertical angles, so they have the same measurements.
Also, x and the other angle across from it are also vertical angles.
88 + 2n = 360
2n = 272
n = 136
Therefore,
x = 44
y = 136
z = 136
can you add fractions with unlike denominators? if so what do you have to do.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.
To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
