The total money you have is $40.14.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now it is given that,
There are 7 times as many nickels as pennies
Let there are n nickles and p pennies.
⇒ p = 7n
Now, there are 16 nickels and pennies altogether
⇒ p + n = 16
Put p = 7n we get,
⇒ 7n + n = 16
⇒ 8n = 16
⇒ n = 16/8
⇒ n = 2
Therefore, p = 7*2
⇒ p = 14
Thus there 14 pennies and 2 nickels.
Now, since 1 penny = 0.01 dollars
and 1 nickel = 20 dollars
⇒ 14 pennies = 14*0.01 dollars = 0.14 dollar
and, 2 nickel = 2*20 dollars = 40 dollars
So, Total money = $40 + $0.14
⇒ Total money = $40.14
Thus, the total money you have is $40.14.

Answer: 582 miles per hour
Step-by-step explanation:
581.603 miles per hour
Round= 582
The speed of an airplane in miles per hour is 581.60 miles/hour.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.
Given the speed of an airplane = 260 m/sec
Since,
1 mile = 1.60934 kilometer
1 km = 1000 meter
So,
1 mile = 1609.34 meter
1 m = (1/1609.34) mile
And,
1 hour = 360 seconds
1 s = (1/360)hour
So,
260 m/sec = 260 (3600/1609.34) miles/hour
⇒ 581.60 miles/hour.
Hence "The speed of an airplane in miles per hour is 581.60 miles/hour".

c) Find the value of inverse function when x = 8.3
[tex]P^{-1}[/tex](8.3) = 2.5*8.3 - 14.25 = 6.5 gramsangle W and angle Y are supplementary. If
the measure of angle W = 5x + 20 and the measure of angle Y = 4x - 11, find the measure of angle W
and Y
Answer: angle of w is 115 degrees and angle of y is 65 degrees.
Step-by-step explanation: in the picture.
Answer:
Angle W = 115° Angle Y = 65°angle W and angle y are supplementary
that is angle W + angle Y = 180°
angle w = 5x + 20
angle y = 4x - 11
putting this value in above equation
we get
5x + 20 + 4x - 11 = 180
5x + 4x + 20 - 11 = 180.
9x + 9 = 180
9x = 180 - 9
9x = 171
x = 19
angle W= 5x + 20
= 5(19)+ 20
= 95 + 20
= 115°
angle y = 4x - 11
= 4(19) - 11
= 76 - 11
= 65

Hi everyone, stay safe, I need help on this, it’s about Triangles.
Answer:
Right scalene triangle
Acute equilateral triangle
Step-by-step explanation:
For the first triangle, we will use the Converse of the Pythagorean Theorem:
If c² < a² + b², then it means that it is an acute triangle.
If c² = a² + b², then it means that it is a right triangle.
If c² > a² + b², then it means that it is an obtuse triangle.
For the first triangle, let c = 25 yd, a = 7 yd, and b = 24 yd
c² = a² + b²
25² = 7² + 24²
625 = 49 + 576
625 = 625 (True statement).
Therefore, the first triangle is a right triangle. At the same time, each angle have different measures, making it a scalene triangle. Therefore, the first triangle is an example of a right scalene triangle.
For the second triangle, since all sides are equal, it doesn't matter which side we label as a, b, or c.
Let's see which type of triangle it is according to its sides:
c² = a² + b²
32² = 32² + 32²
1024 < 2048
Therefore, it is an acute triangle. At the same, the second triangle has equal sides, making it an equilateral triangle. Therefore, the second triangle is an example of an acute equilateral triangle.

Step-by-step explanation:
Each column represent the number of packages of pencils and the total number of pencils you would have.
So column 1 says 1/2 package of pencils and there are 24 pencils in that package so you have 12 pencils total not 24 like it says.
Column 2 says 1 package of pencils. Since there are 24 pencils in a package, now you would have 24 pencils total.
Column 3 says 3 packages. 3 x 24 = 72 pencils total
Column 4 says 4 packages. 4 x 24 = 96 pencils total
Colum 5 says 6 1/2 packages. 6 x 24 = 144 and you know 1/2 of a package equals 12. So 144 + 12 = 156 total pencils.

The equivalent expression is 7x - 2(1.3x + 3.5) = 5.4x - 7 and non-equivalent expression is 8 - 4(-2.2x + 1.1) = 8.8x + 12.4 .
What are linear expression ?A linear expression only has one or two variables. No variables in a linear expression is raised to power greater than 1 or used as denominator of a fraction.
Now the given expressions are,
7x - 2(1.3x + 3.5) = 5.4x - 7 ....(i)
and,
8 - 4(-2.2x + 1.1) = 8.8x + 12.4 .....(ii)
Taking equation (i)
7x - 2(1.3x + 3.5) = 5.4x - 7
So, LHS = 7x - 2(1.3x + 3.5)
⇒ LHS = 7x - 2.6x + 7
or, LHS = 5.4x + 7
⇒ LHS = RHS
So these expressions are equivalent.
Taking equation (ii),
8 - 4(-2.2x + 1.1) = 8.8x + 12.4
So, LHS = 8 - 4(-2.2x + 1.1)
⇒ LHS = 8 - 8.8x - 4.4
⇒ LHS = -0.8x - 4.4
⇒ LHS ≠ RHS
So these expressions are not equivalent.
Thus, the equivalent expression is 7x - 2(1.3x + 3.5) = 5.4x - 7 and non-equivalent expression is 8 - 4(-2.2x + 1.1) = 8.8x + 12.4.

A. 10 minutes
B. 15 minutes
C. 45 minutes
D. 60 minutes
Answer: 15 minutes
Step-by-step explanation:
4 stamping machines in factory

Carrie is making a colorful beaded necklace. She has 3 times as many green beads
as red beads, and twice as many blue beads beads. If she has 150 beads
all together, how many of the beads are green?
Answer:
45 green beads
.
Step-by-step explanation:
Let the number of red beads be 'x'
Given that, Carrie has 3 times as many green beads as red beads
Number of green beads = 3 times number of red beads
Number of green beads = 3x
She 2 as many blue beads as green beads
Number of blue beads = 2 times the number of green beads
Number of blue beads = 2(3x) = 6x
She has 150 total
Therefore,
Number of red beads + Number of green beads + Number of blue beads = 150
x + 3x + 6x = 150
10x = 150
x = 15
Thus, number of green beads = 3x = 3(15) = 45
Thus there are 45 green beads
I hope this helps
The question requires finding total green beads she has
There are 45 green beads
let
number of red beads = x
number of green beads = 3x
number of blue beads = 2(3x)
Total beads = 150
Total beads = red beads + green beads + blue beads
150 = x + 3x + 2(3x)
150 = 4x + 6x
150 = 10x
divide both sides by 10
x = 150/10
x = 15
Therefore,
number of red beads = x
= 15 beads
number of green beads = 3x
= 3 × 15
= 45 beads
number of blue beads = 2(3x)
= 2(3 × 15)
= 2(45)
= 90
