Andre is making paper cranes to decorate for a party. He plans to make one large paper crane for a centerpiece and several smaller paper cranes to put around the table. It takes Andre 10 minutes to make the centerpiece and 3 minutes to make each small crane. He will only have 30 minutes to make the paper cranes once he gets home.
Andre wrote the inequality 3x + 10 ≤ 30 to plan his time. Describe what x, 3x, 10, and 30 represent in this inequality.
Solve Andre’s inequality and explain what the solution means.
Answer:
6 small cranes
Step-by-step explanation:
3x + 10 is less than or equal to 30
3 is the minutes for the small cranes
X is the amount of small cranes
10 is the minutes for the large crane
30 is the total time limit
first, subtract 10 from 30, which gives you 20 so
3x is less than or equal to 20.
to figure this out, divide 20 by 3, which gives you 6 with a remainder of two minutes.
Andre can make 6 small cranes.

Courtney has $4.85 in nickels, quarters, and dimes. She has12 quarters and 7 nickels. How many more dimes than nickels does she have?
A. 8
B. 12
C. 15
D. 30
Answer:
8 dimes
Step-by-step explanation:
A quarter is $0.25, so 0.25 should be multiplied by the number of quarters she has:
0.25 * 12 = 3.00
A nickel is $0.05, so 0.05 should be multiplied by the number of nickels she has:
0.05 * 7 = 0.35
If we add this together, we get 3.35, and the rest of the money Courtney has is in dimes. First, find the amount of money left:
4.85 - 3.35 = 1.50
A dime is $0.10, so divide the amount of money left by 0.10 to find the number of dimes Courtney has:
1.50 ÷ 0.10 = 15
Subtract 15 by the number of nickels Courtney has to find how many more dimes she has than nickels:
15 - 7 = 8 dimes

450
Triangle not drawn to scale
A. 2-3
B. 4/2
C.
D. JE
The value of cos 45° in the given triangle is 1/√2, Option C is correct.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
In the given right triangle the hypotenuse is 8√2
In the given triangle the two legs are equal.
Let x be the length of the two legs
By Pythagoras theorem, let us find the length of a leg.
x²+x²=(8√2)²
2x²=64(2)
2x²=128
Divide both sides by 2
x²=64
Take square root on both sides
x=8
Now let us find the cosine function, the ratio of adjacent side and hypotenuse
cos45 = 8/8√2
=1/√2
Hence, the value of cos 45° in the given triangle is 1/√2, Option C is correct.

A man is 32 years older than his daughter and the product of their ages is 320..
(a) Find the ages of the man and the daughter.
(b) In how many years' time will the daughter's age be one- third of her father's age?
Pls help me
The age of the man is 40 years and that of his daughter is 8 years respectively.
How to solve a linear equation?A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.
Suppose the age of man be x.
Then, age of his daughter is x - 32.
As per the question the following equation can be formed for the product of ages as ,
x(x - 32) = 320
⇒ x² - 32x - 320 = 0
⇒ x = 40, -8
Since, age of a person cannot be a negative value, it is taken as positive.
Thus, the age of daughter is 40 - 32 = 8
Hence, the age of the man and his daughter is obtained as 40 and 8 years respectively.

There are some Chicken and rabbits in a cage. There are 20 heads and 62 feet in total, the question is: how many chicken and rabbits in the cage?
Answer:There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?
Step-by-step explanation
There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?
Legs of a chicken = 2
Legs of a rabbit = 4
Total heads = 72
Total legs= 200
Let's assume that each of them has minimum 2 legs.
So 72*2 = 144 legs
Remaining legs: 200-144= 56
These remaining legs belong to rabbit because rabbit has 4 legs each.
2*Rabbits= 56
Rabbits= 56/2 = 28
Out of 72, 28 are rabbits. So there are 72-28= 44 chicken.

A new homeowner needs to determine the length of his rectangular backyard before he goes to the store for
fencing. He knows that the area of the yard is 51 square meters and that the width is 5.2 meters longer
than the length. Which equation could be solved to determine the dimensions of the backyard, where the length
is / and the width is w?
0=w2+5.2w -51
o
0=12+5.21-51
4w + 10.4 = 51
о
41 +10.4 = 51
Answer:
The equation used to solved to determine the dimensions of the backyard is 51 = 4w - 10.4
Step-by-step explanation:
As given,
The backward is rectangular in shape
Also , we know that
Area of rectangle = 2 ( Length + Breadth )
Also, given,
Breadth of the backyard = 5.2 + Length of the backyard
Let
length of the backyard = l
Breadth of the backyard = w
∴ we get
w = 5.2 + l
⇒l = w - 5.2
and
Area = 2 ( l + w)
⇒51 = 2( w - 5.2 + w)
⇒51 = 2 ( 2w - 5.2)
⇒51 = 4w - 10.4
So, the equation used to solved to determine the dimensions of the backyard is 51 = 4w - 10.4
By solving we get
4w = 51 + 10.4
⇒4w = 61.4
⇒w = [tex]\frac{61.4}{4}[/tex] = 15.35
⇒ w = 15.35
⇒ l = w - 5.2 = 15.35 - 5.2 = 10.15
⇒l = 10.15
So the dimensions of the backyard = l × b = 10.15 m × 15.35 m

in the figure below, what are the values of x and y? What are the measures of the four angles in the figure
Answer:
a. x=57.6, y=44.8
Step-by-step explanation:
Named the angles, check the picture for that
<ABD+<ACD=180 (Opposite angles of a quadrilateral is supplementary (180 degrees)
<CAB+<BDC=180 (Opposite angles of a quadrilateral is supplementary (180 degrees)
therefore:
a. 3y+x-12=180.............. equ 1
2x+y+20=180.............equ 2
From equ 1
x+3y=180+12
x+3y=192...............equ 3
From equ 2
2x+y=180-20
2x+y=160.............equ 4
Equate equ 3 and equ 4
x+3y=192...............equ 3
2x+y=160.............equ 4
Using elimation method
x+3y=192...............equ 3
2x+y=160.............equ 4
Multiple equ 3 by 1 and equ 4 by 3
x+3y=192...............equ 3 ×1
2x+y=160.............equ 4 ×3
x+3y=192
6x+3y=480
Subtract
-5x+0=-288
-5x=-288
x=57.6................... Equ 5
Replace 57.6 for x in equ 3
x+3y=192...............equ 3
57.6+3y=192
3y=192-57.6
3y=134.4
y=44.8
B. <CAB= 2x=2×57.6=115.2
<ABD= 3y=3×44.8= 134.4
<ACD=x-12=57.6-12=45.6
<BDC=y+20=44.8+20=64.8

Which equation represents exponential decay?
Answer:
The answer is C
Step-by-step explanation:
Exponential decay is when b is between 0 and 1.
Answer:
C. y = 10(0.13)^x.
Step-by-step explanation:
exponential decay is decreasing from what I remember from Algebra 1 Honors. So therefore, your only answer can be C. y = 10(0.13)^x.
The others all increase because 31, 3.1, 1.03 are all bigger than 1 which means that they increase while .13 decreases.
C. y = 10(0.13)^x.

Answer:
6.75
Step-by-step explanation:
We are given that function
[tex]f(x)=\frac{9x-18}{4}[/tex]
5 is an element in the domain of f(x)
i.e
x=5
We have to find the corresponding element of 5 in the range of f(x).
Substitute x=5 in the given function
[tex]f(5)=\frac{9\times 5-18}{4}[/tex]
[tex]f(5)=6.75[/tex]
Hence, the corresponding element of 5 is 6.75 in the range.
Ranbir bought a rectangular field of area 24000 square metres and width 120 m. He wants to fence it with two rounds of wire. Find the length of wire that will be required to fence the field.
Answer:
640 metres
Step-by-step explanation:
Area of a rectangular field = 24000 square metres
Width of a rectangular field = 120 metre
Also,
Area of a rectangular field = Length × Breadth
24000 = Length × 120
Length = [tex]\frac{24000}{120}=200[/tex] metre
Length of wire required to fence the field = Perimeter of the rectangular field
= 2 (length + width)
= 2 (200 + 120)
= 2 (320)
= 640 metres
