Final answer:
To find the expression representing segment PS, we add the expressions for segments PR (4x - 2) and RS (3x - 5) to get PS as 7x - 7.
Explanation:
The question asks us to determine the expression that represents the segment PS given the expressions for segments PR and RS. PR is given as 4x - 2 and RS is given as 3x - 5. To find the length of PS, we add PR and RS because PS is the sum of PR and RS when they form a continuous line segment. Therefore, PS is (4x - 2) + (3x - 5). Simplifying this expression, we get PS as 7x - 7.
7:( 4/11 m)=56:3.2 solve.
Answer:
m=1.1
Step-by-step explanation:
Divide one side by 8, then you get 7:(4/11 m)=7: 0.4
Basically then 4/11 m=0.4
4/11 m=2/5
m=(11/4)(2/5)
m=11/10, 1 1/10, 1.1
The value of m that satisfies the proportion 7:(4/11 m) = 56:3.2 is 1.1
How to determine the solution to the expressionFrom the question, we have the following parameters that can be used in our computation:
7: (4/11m) = 56 : 3.2
Cross-multiply the proportions
7 * 3.2 = (4/11 m) * 56
Simplify both sides:
22.4 = (4/11 m) * 56
Divide both sides by 56
(4/11 m) = 22.4 / 56
Simplify the right side
(4/11 m) = 0.4
Multiply both sides by (11/4)
m = 0.4 * (11/4)
So, we have
m = 1.1
Hence, the calculated value of "m" that satisfies the proportion 7:(4/11 m) = 56:3.2 is 1.1

A rectangle and a triangle have the same area. If their bases are the same lengths, how do their heights compare? Justify your answer.
The triangle's height would have to be 2 times that of the rectangles. To know this, you canlook at the formulas for the Area of each shape.
Rectangle: bh
Triangle: bh/2
A triangle is just a rectangle cut in half. In order for the areas to be the same asleep as the bases, the only way it can be true is if the height were 2 times larger than the height of the rectangle.

1. A right circular cylinder has a height of 5 in. and a base area of 20 in2. What is the volume of the cylinder? Use π = 3.14.
2. A cylinder has a base area of 20.7 in2 and the volume is 207 in3. What is the height of the cylinder?
1. Volume of a cylinder is πr^2h
Area of the base would be πr^2
Volume would be the height x the area of the base:
Volume = 5 x 20 = 100 cubic in.
2. Divide the volume by the area:
207 / 20.7 = 10
The height is 10 inches.
Answer:
1. V = 100 in³2. h = 10 inStep-by-step explanation:
The formula of a volume of a cylinder:
[tex]V=Bh[/tex]
B - base area
h - height
1. We have
h = 5in, B = 20 in².
Substitute:
[tex]V=(5)(20)=100\ in^3[/tex]
2. We have
B = 20.7 in², V = 207 in³.
Substitute:
[tex]207=20.7h[/tex] divide both sides by 20.7

Which value for x makes the sentence true?
8x + 4 = 20
A. x = 12
B. x = 4
C. x = 8
D. x = 2
8x+4= 20
move +4 to the other side
sign changes from +4 to -4
8x+4-4= 20-4
8x= 20-4
8x= 16
divide both sides by 8 to get x by itself
8x/8= 16/8
Cross out 8 and 8, divide by 8 and then becomes 1*1*x= x
x= 16/8
Answer: D. x = 2
In order to get the answer to this question you will have to solve the equation before you can get the answer.

Answer:
The measure of angle L is 40°
Step-by-step explanation:
we know that
In a parallelogram the opposite angles are congruent and the opposite sides are congruent and parallel
see the attached figure to better understand the problem
so
In this problem
∠L≅∠N
∠M≅∠O
we have
∠L=(3x-20)°
∠N=(2x)°
so
equate the angles and solve for x

17. Tina runs at a rate of 8 miles per hour. At that rate,
how many miles will she run in 12 minutes?
A. Í
B.
C. 1
Answer:
1.6 miles
Step-by-step explanation:
60/12=5
which will mean 1/5=.2
.2x8=1.6 miles
Tina's running rate is 8 miles per hour. In 12 minutes, she will cover a distance of 1.6 miles.
To calculate the number of miles Tina will run in 12 minutes, we need to convert the time to hours since her rate is given in miles per hour.
Since there are 60 minutes in an hour, we divide 12 minutes by 60 to convert it to hours:
12 minutes / 60 = 0.2 hours
Now, we can calculate the distance Tina will run by multiplying her rate by the time:
Distance = Rate * Time = 8 miles per hour * 0.2 hours
Distance = 1.6 miles
Therefore, Tina will run 1.6 miles in 12 minutes.

5x = 35,000
x = 35,000/5

Rewrite the radical expression as an expression with rational exponents.
fifth root of x to the power of 9
a- x to the five ninths power
b-x to the nine fifths power
c-5x9
d- 9x5
The fifth root of x can be expressed as a power of 1/5 this way:
x^(1/5).
Now raise [x^(1/5)] to the 9th power.
[x^(1/5)]^(9)
Multiply the powers to complete the problem.
x^(9/5)
Answer: Choice B.
The expression 'fifth root of x to the power of 9' can be rewritten as 'x to the 9/5 power' in terms of rational exponents, this is option b.
Explanation:The correct rewrite of the expression, 'fifth root of x to the power of 9', utilizing rational exponents instead of a radical approach, is expressed as x to the 9/5 power. When translating a radical to a rational exponent, the index of the root becomes the denominator and the power of the term inside the root becomes the numerator.
So, fifth root of x to the power of 9 translates to x to the power of 9/5, which corresponds to option b.

Tomas and Kyle each bought a shirt at the school store. Tomas gave the cashier a $20 bill and received $6.15 in change. Kyle
gave the cashier a $10 bill and received $1.06 in change. Which statement about the cost of the shirts is true?
Tomas's shirt costs $5.09 more than Kyle's shirt.
Answer:
for tomas 19.100-6.15=$13.85dollars
so tomas's shirt cost $13.85
for kyle 9.100-1.06=$8.94
13.85-8.94=4.91
so tomas's shirt $4.91more than Kyle's shirt
Answer:
Tomas's shirt costs $4.91 more than Kyle's shirt.
Step-by-step explanation:
It is given that Tomas gave the cashier a $20 bill and received $6.15 in change. So, the cost of Tomas's shirt is the difference between the amount he gave and he received in change.
Cost of Tomas's shirt = $20 - $6.15 = $13.85
Kyle gave the cashier a $10 bill and received $1.06 in change. So,
Cost of Kyle's shirt = $10 - $1.06 = $8.94
The cost of Tomas's shirt is $13.85 and the cost of Kyle's shirt is $8.94.
Cost of Tomas's shirt is more that the cost of Kyle's shirt.
$13.85- $8.94=$4.91
Therefore, Tomas's shirt costs $4.91 more than Kyle's shirt.
How do I solve 80+(-22 4/15)
Final answer:
The expression 80 + (-22 4/15) is solved by converting the mixed number to an improper fraction, aligning the fractions by the same denominator, and then adding them to get 58 4/15 as the result.
Explanation:
To solve the expression 80 + (-22 4/15), follow these steps:
First, convert the mixed number -22 4/15 into an improper fraction. To do this, multiply the whole number by the denominator and add the numerator: (-22 × 15) + 4 = -330 + 4 = -326, so the mixed number becomes -326/15.
Next, since 80 is a whole number, we can convert it into a fraction with the same denominator of 15 to make it easier to add to -326/15. To do that, multiply 80 by 15/15, which is the equivalent of 1, to get the fraction 1200/15.
Now, add the two fractions: 1200/15 + (-326/15) = (1200 - 326)/15 = 874/15.
This fraction can be simplified back into a mixed number by dividing the numerator by the denominator: 874 ÷ 15 = 58 with a remainder of 4, so the mixed number is 58 4/15.
Therefore, the solution to the expression 80 + (-22 4/15) is 58 4/15.

The vertices of pentagon PQRST are P(0, 1), Q(2, 2), R(5, 3), S(4, 0), and T(1,−1). If pentagon PQRST is reflected over the y-axis which vertex will NOT change its coordinates?
Answer:
P(0,1)
Step-by-step explanation:
The vertices of pentagon PQRST are P(0, 1), Q(2, 2), R(5, 3), S(4, 0), and T(1,−1).
If a figure reflected across y-axis, then the relation between preimage and image is
[tex](x,y)\rightarrow (-x,y)[/tex]
If the pentagon PQRST reflected over the y-axis, then vertices of image are
[tex]P(0,1)\rightarrow P'(0,1)=P[/tex]
[tex]Q(2,2)\rightarrow Q'(-2,2)[/tex]
[tex]R(5,3)\rightarrow R'(-5,3)[/tex]
[tex]S(4,0)\rightarrow S'(-4,0)[/tex]
[tex]T(1,-1)\rightarrow T'(-1,-1)[/tex]
Therefore, only vertex P will not change its coordinates after reflection.

Have a nice day!!! :-)
9.054 X 10-6 is represented by the conventional form 0.000009054.
Explain about the standard form?Any value between 1.0 and 10.0 that can be expressed as a decimal number and multiplied by a power of 10 is referred to as being in standard form.
A linear equation has the conventional form Ax+By=C. A slope-intercept form equation (y=mx+b) must have the x and y on the same side of the equal sign and the constant on the opposite side in order to be converted to standard form.
Any value between 1.0 and 10.0 that can be expressed as a decimal number and multiplied by a power of 10 is referred to as being in standard form. If you look closely, you will see that 1.23 is a decimal between 1.0 and 10.0, and as a result, we have the standard form of 123,000,000 as 1.23 108.
