Answer: 0.002 inches
Step-by-step explanation:
A stack of 500 pieces of paper is 1.015 inches tall. The appropriate estimate for the thickness of each piece of paper would be gotten by dividing 1.015 by 500. This will be:
= 1.015 / 500
= 0.00203
= 0.002 inches

What number is she thinking of?
Question:
Sue is thinking of a number 3/8 of 88 = 1/3 of her number
what number is she thinking of
Answer:
[tex]x = 99[/tex]
Step-by-step explanation:
Represent the number with x.
So, we have:
[tex]\frac{3}{8} * 88 = \frac{1}{3} *x[/tex]
Multiply through by 3
[tex]3 * \frac{3}{8} * 88 = \frac{1}{3} *x * 3[/tex]
[tex]3 * \frac{3}{8} * 88 = x[/tex]
[tex]3 * 3 * 11 = x[/tex]
[tex]99= x[/tex]
[tex]x = 99[/tex]
Hence, she is thinking of 99

A. It will be twice as much as because the height is increased by 2
Please answer please ASAP * please don’t answer if you don’t know please .
Answer:
x = 26
Step-by-step explanation:
1. Information
One can partition this figure into three different parts, two congruent triangles, and one rectangle. To find the value of x, one has to find the base of the two triangles, and then the base of the rectangle. Since opposite sides are congruent, the base of the rectangles is 10. To find the base of the triangle, one has to use the Pythagorean theorem.
2. Base of the rectangle
Again, opposite sides are congruent, hence the base of the rectangle is equivalent to the top part. Hence the base is 10.
3. Base of the triangle
Use the Pythagorean theorem;
[tex]a^{2}+b^{2} = c^{2}\\a-leg\\b-leg\\c-hypotenuse[/tex]
Substitute in the given value and solve
[tex]a^{2}+15^{2} = 17^{2}\\a^{2} + 225 = 289\\a^{2} = 64\\a = 8[/tex]
4. Finding x
There are two congruent trinagles, hence one has to add the base of the triangle twice. The equation will be
x = base_of_triangle + base_of_rectagle + base_of_triangle
x = 8 + 10 + 8
x = 26
What is the slope of a line perpendicular to the line whose equation is 10 x + 6 y = − 84 10x+6y=−84.
Answer:
3/5
Step-by-step explanation:
The equation of a line is written as
y = mx + b where
m is the slope
b is the y-intercept.
We put the given equation above in that form
10x + 6y = - 84
6y = -10x - 84
Divide both sides by 6
y = -10x/6 - 84/6
y = -5x/3 - 14
y = -5/3x - 14
The slope of this line is -5/3
But we are told that: the slope of the line is perpendicular to the line
Hence: we find the reciprocal of , -5/3
This is = 3/5
Therefore, the slope of a line perpendicular to the line whose equation is 10x + 6y = −84 is 3/5
if 8n = 128, n equals
Answer:
16
Step-by-step explanation:
128/8 = 16
n= 16
The value of n is equal to 16.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
WE are given an expression as;
8n = 128
We need to find the value of n.
8n = 128
n= 128/8 = 16
n= 16
Hence, the value of n is equal to 16.

i need some help im stuck
Answer:
16 miles an hour
Step-by-step explanation:
40 / 2.5 = unit rate
Answer:
16
Step-by-step explanation:
40÷2.5=16
So 1 hour is 16 because if you multiply it by 2.5 it is right.
(2×16)+(16×0.5)=40
32+8=40.

Can somone help me on this with an explanation PLZ :(
Clare went to a concession stand that sells pretzels for $3.25, drinks for $1.85, and bags of popcorn for $0.99 each. She bought at least one of each item and spent no more than $10. Could Clare have purchased 2 pretzels, 2 drinks, and 2 bags of popcorn? Explain your reasoning. Check your work with the video when you are ready
Answer:
No.
Step-by-step explanation:
Price of each pretzel = $3.25
Price of each drink = $1.85
Price of each bag of popcorn = $0.99
Maximum money to be spent = $10
Price of two pretzels = $3.25 [tex]\times[/tex] 2 = $6.5
Price of two drink = $1.85 [tex]\times[/tex] 2 = $3.70
Price of two bags of popcorn = $0.99 [tex]\times[/tex] 2 = $1.98
Total money spent for buying two items of each type = $6.5 + $3.70 + $1.98 = $12.18
The money spent when 2 pretzels, 2 drinks and 2 bags of popcorn are bought is $12.18.
But maximum money available is $10.
Therefore, Clare would not be able to buy 2 pretzels, 2 drinks and 2 bags of popcorn with the amount of money available.

Answer:
The budget for dances is $380
Step-by-step explanation:
If we know that the ratio between student government budget for dance and charity event is 5:7 this means that there is some amount of money that fits 5 times into the student government budget for dance and 7 times into the budget for the charity events. So in order to find what is the value of that among we divide $532.00 by 7, and then multiply that amount by 5 to get the budget for the dance events. So we do........
$532.00 / 7 x 5 = $76 x 5 = $380
Umer is 5 years older than Abdullah. If the product of their ages is 234. How old is
Abdullah?
Answer:
112
Step-by-step explanation:
234:2=117
117+5=122
--->234-122=112
Answer:
Abdullah is 46.8 years old.
Step-by-step explanation:
Umer is 5 years old and the product of their ages is 234 so that means Abdullah is 46.8 years old.
5*46.8 = 234

10 A solid metallic cylinder of radius 14 cm and
height 21 cm is melted and recast into equal
small spheres each of radius 7/2 cm. Find then
number of spheres formed.
Answer:
72 spheres are formed
Step-by-step explanation:
We start by calculating the volume of the metallic cylinder
Mathematically, we have this as;
V = pi * r^2 * h
V = pi * 21 * 14^2
V = 4116 π cm^3
The volume of each small sphere is;
V = 4/3 * pi * r^3
= 4/3 * π * 7/2^3 = 57.167 π cm^3
To get the number of small spheres, we simply divide the volumes
That will be 4116 pi / 57.167 pi = 72

Given the frequency table, what percentage of the students that like rock are also in grades 11–12? Round to the nearest whole percent.
Band Preference for School Dance
Rap Rock Country Row totals
Grades 9–10 40 30 55 125
Grades 11–12 60 25 35 120
Column totals 100 55 90 245
10%
21%
25%
45%
Answer:
d. 45%
Step-by-step explanation:
According to the frequency table there are 30 sudents who like rock in grades 9-10 and 25 students that like rock and are in grades 11-12.
25 ÷ 55 = n ÷ 100
25 · 100 = 55 · n
2500 ÷ 55 = n n = 45.454545 n = 45%
55 is the total amount of students that like rock
25 is the total amount of students that like rock in grades 11-12
100 is the total percentage

Answer:
x=10
Step-by-step explanation:
Using Pythagoras theorem
H^2=O^2+A^2
26^2=24^2+A^2
676= 576+A^2
676-576= A^2
100= A^2
square root both sides
10= A
Therefore, x=10
If the measure of Angle B E C is (2 x + 3) degrees and x = 30, which expression could represent the measure of Angle A E D?
Lines A C and B D intersect at point E.
(4 x minus 3) degrees
(3 x minus 27) degrees
(5 x minus 33) degrees
(x + 43) degrees
Answer:
(3x−27)o
Step-by-step explanation:
we know that
m\angle BEC=m\angle AEDm∠BEC=m∠AED ----> by vertical angles
we have
m\angle BEC=(2x+3)^om∠BEC=(2x+3)o
The value of x is given
x=30
so
m\angle BEC=(2(30)+3)=63^om∠BEC=(2(30)+3)=63o
That means that the measure of angle AED is also 63 degrees
so
The expression that could represent the measure of Angle A E D is
(3x-27)^o(3x−27)o
because
For x=30
(3(30)-27)=63^o(3(30)−27)=63o
Answer:
(3x−27)o
