Answer:
128 ÷ 4 = [tex]\frac{128}{4}=32[/tex]
Step-by-step explanation:
Total number of photos = 128
Number of photo albums = 4
Alex has 128 photos of his friend to display equally in 4 photo albums.
Equation that can be used to find number of photos in each album =
Number of photo albums ÷ Total number of photos
= 128 ÷ 4
= [tex]\frac{128}{4}=32[/tex]
Janelle spots some dolphins in the ocean. Her father draws a diagram to show how far down they can go. How far is this relative to sea level? What would an altimeter read at this depth?
The diagram is missing, so i have attached it.
Answer:
-1000 ft
Step-by-step explanation:
From the diagram attached, we see that they went 1000 ft below the sea level.
Now an altimeter is used to measure altitude depth of an object relative to a fixed level which in this case the fixed level is the top of sea. Since the depth in this case is below sea level, it will be negative.
Thus,the altimeter will read -1000 ft
Answer:
The dolphins are shown 1,000 feet below sea level. The altimeter reading would be -1,000 feet.

Out of a total of 50 high school students, 14 plan to go to the basketball playoff game Friday night if there are 1450 students at the school, which is the best prediction of how many of the students will attend the game?
Answer:
1131 students, is the best prediction.
Step-by-step explanation:
1450 divided by 50 = 29
50 - 14 = 36
36 x 29 = 1131

Answer: a parallelogram
If y = x² + 2x + 3, find the value of y when x = -1
Answer:
y = 2
Step-by-step explanation:
Given
y = x² + 2x + 3 ← substitute x = - 1
y = (- 1)² + 2(- 1) + 3 = 1 - 2 + 3 = 2

Answer:
C.
Step-by-step explanation:
14/3 = 4.66
/2/=2.33
-14/4 = -3.5
So the numbers are 4.66, 4.3, 2.33, 1.3, -2 and -3.5
So the numbers are -14/4, -2, 1.3,/2/, 4.3, 14/3

Answer:
C. [tex]\sqrt{3x^2+21x}[/tex]
Step-by-step explanation:
When one multiplies two radicles, one multiplies each term in the radical by the term in the other radical, then one simplifies the result and puts the radical sign over the result. If there are any perfect squares one will take the terms out. In this scenario, such is not the case.
[tex]\sqrt{3x}*\sqrt{x+7}\\\\\sqrt{3x(x+7)}\\\\\sqrt{3x^2+21x}[/tex]
Express 2 x 2 x 2 x 2 x 2 in index notation.
Given:
The expression is
[tex]2\times 2\times 2\times 2\times 2[/tex]
To find:
The index notation of the given expression.
Solution:
Index: The power of a number and a variable is called its index.
Index notation: The expression which has a base and a power.
In the given expression 2 is multiplied 5 times, so by using the property of exponent we get
[tex]2\times 2\times 2\times 2\times 2=2^{1+1+1+1+1}[/tex] [tex][\because a^ma^n=a^{m+n}][/tex]
[tex]2\times 2\times 2\times 2\times 2=2^{5}[/tex]
Therefore, the index notation of the given expression is [tex]2^5[/tex].

A rectangle has a perimeter of 26 inches. All of its side lengths are doubled to create a new rectangle.
a. How does the perimeter of the new rectangle compare to the perimeter of the original rectangle?
b. How does the area of the new rectangle compare to the area of the original rectangle?
Answer:
a) the new perimeter is 2 times the old perimeter
b) the new area is 4 times the old area
Step-by-step explanation:
b) the doubling of the length and width affects the area formula like this:
old triangle area formula = 1/2bh
new triangle area formula = 1/2(2b)(2h), you see the 2 x 2 causes the area to be 4 fold

4y-12=x-4
4y+x-12+4=0
4y+x-8=0

Answer:
x=128
Step-by-step explanation:
180-52=128
Answer: x= 128 degrees
Step-by-step explanation:
Angle “x” and angle with measure of 52 degrees are a linear pair.
Linear pairs sum to 180.
52+x=180. Subtract 52 from both sides.
X= 128
*OR you can use angles around a point sum to 360 degrees.
52+38+142+x = 360. Combine like terms.
232+x= 360. Subtract 232 from both sides.
X= 128
The square of a number 60 greater than half of the number. Form a
quadratic equation and solve to determine the possible values of the
number.
Answer:
The number could be [tex]-7.5[/tex] or [tex]8[/tex].
Step-by-step explanation:
I'm going to assume this means "The square of a number is 60 greater than half of the number." Let the number be [tex]x[/tex]. The square of [tex]x[/tex] will be [tex]x^{2}[/tex]. "is" denotes that we use the "[tex]=[/tex]" sign, so our equation so far is [tex]x^{2} =[/tex] . Half of [tex]x[/tex] is [tex]\frac{1}{2}x[/tex], and "greater than" implies addition, so [tex]60[/tex] greater than [tex]\frac{1}{2}x[/tex] is [tex]\frac{1}{2}x+60[/tex]. Therefore, the equation is [tex]x^{2} =\frac{1}{2}x+60[/tex].
Solving for [tex]x[/tex], we get:
[tex]x^{2} =\frac{1}{2}x+60[/tex]
[tex]2x^{2} =x+120[/tex] (Multiply both sides of the equation by [tex]2[/tex] to get rid of the fraction)
[tex]2x^{2} -x-120=0[/tex] (Subtract [tex]x+120[/tex] from both sides of the equation to make it easier to solve)
[tex]2x^{2} +15x-16x-120=0[/tex] (Split [tex]-x[/tex] into [tex]15x-16x[/tex] to make the LHS easier to factor)
[tex]x(2x+15)-8(2x+15)=0[/tex] (Take a common factor out of the first two terms and the last two terms)
[tex](2x+15)(x-8)=0[/tex] (Take another common factor out)
[tex]2x+15=0,x-8=0[/tex] (Zero Product Property)
[tex]x=-7.5,8[/tex] (Solve)

solve for the slope / y-intercept and the equation
Answer:
Slope = -3, Y-intercept = -2, y = -3x -2
Step-by-step explanation:
There are multiple points plotted on the graph, but right now, we only need to focus on two.
(-2, 4) (-1, 1)
Using the ordered pairs, do delta y/ delta x to get the slope
(1-4)/(-1-(-2)
(-3)/(-1+2)
(-3)/(1)
Slope = -3
y = -3x + b
As shown on the graph, the y-intercept is -2. It is when x = 0
So, for the equation, substitute the found values.
y = -3x -2

100% of what number is 27? Provide an exact fraction answer
Answer:
Your answer is 27
I hope I helped, would appreciate brainliest! ;)
Step-by-step explanation:
'Percent (%)' means 'out of one hundred':
27% = 27 'out of one hundred',
p% is read p 'percent',
27% = 27/100 = 27 ÷ 100
Calculate percentage:
'Percentage' is obtained by multiplying 100 by 27%
27% of 100 is equivalent to multiplying them:
27% × 100 = ?
27% × 100 =
(27 ÷ 100) × 100 =
(27 × 100) ÷ 100 =
2,700 ÷ 100 =
27
Proof.
How do we check the result?
If 27% × 100 = 27 =>
Divide 27 by 100...
... And see if we get as a result: 27%
Note:
100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100,
... and its value doesn't change.
n/100 = n%, any number.
Calculate the percent value:
27 ÷ 100 =
0.27 =
0.27 × 100/100 =
(0.27 × 100)/100 =
27/100 =
27%
So we have proved that the calculations are correct.
Answer:
Percentage of
27% of 100 = 27
Answer:
