-5b = -20 b= need help with homwork
Answer:
b = 4
Step-by-step explanation:
you must divide both sides of the equation by -5 to get b by itself. division cancels out multiplication but also keeps both sides equal
b = -20/-5

[tex]\boxed {\boxed {\sf b=8}}[/tex]
Step-by-step explanation:
The Pythagorean Theorem is:
[tex]a^2+b^2=c^2[/tex]
where a and b are the legs and c is the hypotenuse.
In this triangle, 6 and b are the legs, because they form the right angle.
10 is the hypotenuse, because it is opposite the right angle. Plus, it's the longest side.
[tex]a=6 \\b=b\\c=10[/tex]
Substitute the values into the Theorem.
[tex]6^2+b^2=10^2[/tex]
Evaluate the exponents.
6²= 6*6= 36[tex]36+b^2=10^2[/tex]
10²= 10*10= 100[tex]36+b^2=100[/tex]
Subtract 36 from both sides of the equation to isolate the variable (b).
[tex]36-36+b^2=100-36[/tex]
[tex]b^2=100-36[/tex]
[tex]b^2=64[/tex]
b is being squared. The inverse of a square is a square root. Take the square root of both sides of the equation.
[tex]\sqrt{b^2}=\sqrt{64[/tex]
[tex]b=\sqrt{64}[/tex]
[tex]b=8[/tex]
In this triangle, b (the other leg) is equal to 8
What is the approximate circumference of the circle shown below?
A. 37.8 cm
14.8 cm
B. 46.5 cm
C. 23.2 cm
D. 92.9 cm
SUBMIT
The approximate circumference of the circle shown in the image is given as follows:
B. 46.5.
How to obtain the circumference of a circle?The circumference of a circle of diameter d is given by the multiplication of π and the diameter, as follows:
C = πd.
π has the numeric value of 3.14, hence the equation is approximated as follows:
C = 3.14d.
The diameter of a circle is the distance between two points on the circumference of the circle that pass through the center, hence for this problem it is given as follows:
d = 14.8 cm.
Then the circumference of the circle is of:
C = 3.14 x 14.8
C = 46.5 cm.

3/4 of girls in sss1 play basketball and 4/7 play volleyball. Every girl plays at least one of these games. if 27 play both games how many girls are in the class
Answer:
84
Step-by-step explanation:
1/4 of class don't play basketball but do play volleyball
so 9/28 of class play both since 4/7 - 1/4 = 9/28
9/28 of class = 27
1/28 of class = 3
class = 3*28
There are 84 girls in the class.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Girls who plays basketball = (3/4)x
Girls who plays volleyball = (4/7)x
Girls who plays both games = 27
Now, Let us consider total girls in the class = x
So we can write it as mathematical equation as;
⇒ (3/4)x +(4/7)x - 27 = x
By taking L.C.M. -
⇒ (21x+16x)/28 - (27) = x
⇒ 37x/28 = x + 27
⇒ 37x = 28x + (27×28)
⇒ 9x = 27×28
⇒ x = (27×28)/9
⇒ x = 3×28
⇒ x = 84
So, There are total 84 girls in the class.

A hybrid SUV gets 32miles per gallon on the highway driving at a constant 55 miles per hour.At this rate, how many gallons per hour does the hybrid SUV use?
Answer:
a
Step-by-step explanation:
The hybrid SUV uses 32/55 gallons per hour which is the correct answer would be an option (A).
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
The operator that perform the arithmetic operations are called arithmetic operators.
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
Given that a hybrid SUV gets 32miles per gallon on the highway driving at a constant 55 miles per hour
To determine miles per gallon of gas,
We take the 32miles the hybrid SUV travels and divide it by the highway driving at a constant 55 miles per hour
⇒ 32/55
Hence, the hybrid SUV uses 32/55 gallons per hour.

Answer:
4^(5x) = 5x + 2

Esther had five times as many cards as Richard. Esther gave 1/4 of her cards to Richard. Then, Richard gave 1/6 of his cards to Esther in return. In the end, Esther had 90 more than Richard. How many cards did Esther have at first?
Answer:
Esther has 200, Richard has 40
Esther gives Richard 50 cards. Now they have
Esther: 150, Richard: 90
Richard gives Esther 15, so they now have
Esther: 165, Richard 75
Step-by-step explanation:
Answer:
Esther had 200 cards at first
Step-by-step explanation:
Variables:
Esther: 5r
Richard: r
Equalities:
e = 5r
e - e/4 + 1/6 (r + e/4) = 5/6 (r + e/4) + 90
Solve:
Replace e with 5r and solve for r:
e - e/4 + 1/6 (r + e/4) = 5/6 (r + e/4) + 90
5r - 5r/4 + 1/6 (r + 5r/4) = 5/6 (r + 5r/4) + 90
5r - 5r/4 + 1/6 (2.25r) = 5/6 (2.25r) + 90
5r - 1.25r + 0.375r = 1.875r + 90
5r - 1.25r + 0.375r - 1.875r = 90
2.25r = 90
r = 40
Esther: 5r = 5(40) = 200
Richard: r = 40

In the figure below, APQR is a reflection of ATSA.
Two students describe the given triangles as shown:
Student I: Because reflections preserve side lengths, OR a SR, PO TS, and PR TR.SO APORATSR by SSS.
Student II: Because reflections preserve both side lengths and angle measures, ZROP ZRST, OR SR. and PO = TS. SO APOA - ATSR by SAS.
Who has proven APOR - ATSR correctly?
only studenti
only student II
o
both student I and student II
o
neither student I nor student II
Answer:
both student one and student two
Step-by-step explanation:
With the properties of congruent triangle we conclude that the statement of both student I and student II are correct.
Congruent triangle-If the sides of two triangle measure same lengths and the angle have same measures then the two triangle are said to be congruent.
Given-
Statement of student 1-Because reflections preserve side lengths,
[tex]QR \cong SR[/tex],
[tex]PQ \cong TS[/tex],
[tex]PR \cong TR.[/tex] so,
[tex]\bigtriangleup PQR \cong \bigtriangleup TSR[/tex]
In all the three sides of one triangle are equivalent to the corresponding three sides of the second triangle, then the two triangle are said to be congruent by the side side side (SSS) rule. Hence, the above statement is correct.
Statement of student 2- Because reflections preserve both side lengths and angle measures,
[tex]\angle RQP \cong \angle RST[/tex]
[tex]QR \cong SR[/tex]
[tex]PQ \cong TS[/tex]
[tex]\bigtriangleup PQR \cong \bigtriangleup TSR[/tex]
In any two sides and the angle included between the sides of one triangle are equivalent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangle are said to be congruent by the side angle side (SAS) rule. Hence the above statement is correct.
Hence, with the properties of congruent triangle we conclude that the statement of both student I and student II are correct.

What is a graph?A graph represents the data on the vertical and horizontal coordinates so we can see the trend of the data.
A graph is a structure that resembles a set of items in mathematics, more specifically in graph theory, in which some pairings of the objects are conceptually "connected."
The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.
As more people visit the park, the number progressively rises; after a while, it stabilizes; and finally, as more people start to leave, it begins to drop on the graph.
Therefore, the graph is showing the entry of the people in the amusement park.
