find the value of x in the isosceles triangle shown below.
4
6
Answer:
B
Step-by-step explanation:
Pythagorean theorem:
6^2 + (4/2)^2 = x^2
36 + 4 = x^2
40 = x^2
x = [tex]\sqrt{40}[/tex]= [tex]2\sqrt{10}[/tex]
Answer is B
A father is 20 years older than his son. Five years ago,he was three times as old as his son was.Find their present ages
Answer:
Dad=35, Son=15
Step-by-step explanation:
Well since the dad is 20 year older then the son we can call the son x and the dad x+20. Now five years ago the father was 3 times older then the so we construct the following equation:
x+20−5=3(x−5)
x+15=3x-15
x=15
So now we know that the sons age is 15 meanimg that since the dads 20 years older then him, his age is 20+15 which is 35!
convert the following decimals into rational numbers:
1.4325
Answer
[tex]\frac{573}{400}[/tex]
step-by-step explanation:
[tex]\frac{1.4325}{1}[/tex] × [tex]\frac{10000}{10000}[/tex] = [tex]\frac{14325}{10000}[/tex]
Simplify
[tex]\frac{14325}{10000}[/tex] ÷[tex]\frac{25}{25}[/tex] = [tex]\frac{573}{400}[/tex]
"find the area" = _in^2
Answer:
84 in^2
Step-by-step explanation:
Answer:
84in^2
Step-by-step explanation:
First we can calculate the rectangle which would be
6*11=66
then we can calculate the triangle
we know that the base is 6, so if we cut it in half we get two triangles which could get put back together in another rectangle so we would just need to do
6*3=18
then add them together
66+18=84
The number of hot drinks sold in a café decreases as the weather becomes warmer. What type of correlation does this statement show?
Solve for x. (Round to the nearest tenth)
Answer:
13.7
Step-by-step explanation:
fill the numbers in using pythagorean theory
[tex]a^{2} + b^{2} = c^{2}[/tex]
(the hypotenuse has to be [tex]c^{2}[/tex])
[tex]9.2^{2} + b^{2} = 16.5^{2}[/tex]
[tex]84.64 + b^{2} = 272.25[/tex]
[tex]b^{2} = 187.61[/tex]
(to get [tex]b[/tex] alone you have to find the square root of both sides)
[tex]b = 13.69707[/tex]
round that and you get
[tex]b = 13.7[/tex]!

Thank you!!!
Answer:
108.51
Step-by-step explanation:
A triangle has sides with lengths of 7 meters, 10 meters and 13 meters is it a right triangle
Answer:
No
Step-by-step explanation:
7 squared + 10 squared = 149
13 squared = 169
As you can see these two products are not equal. They have to be equal to be a right triangle.
So this triangle is not a right triangle.
Hope that helped you and have a great day!
Answer:
No it is not.
Step-by-step explanation:
Let h = 13, p = 10 and b =7
Using pythagoras theorem,
h² = p² + b²
13² = 10² + 7²
169 = 100 + 49
169 = 149
This is false so the triangle is not a right angled triangle.
The measures of the angles of a triangle are shown in the figure below. Solve for x.
(8x-9)°
63°
70°
Answer:
x= 7
Step-by-step explanation:
Theorem: The sum of the angles of a triangle is 180
Memorize that theorem
8x - 9 + 63 + 70 = 180
8x + 124 = 180
8x = 56
x= 7

find the value (s) of the variables (s) in each parallelogram.
Step-by-step explanation:
As we can see it is a parallelogram so here the diagonals bisect so
6y + 1 = 4y + 9
6y - 4y = 9 - 1
2y = 8
y = 8 / 2
y = 4
2x - 5 =x + 7
2x + x = 7 + 5
3x = 12
x = 12 / 3
x = 4
Hope it will help :)
Write (2x – 1) (3x – 1) in standard form.
Answer:
6x^2-5x+1
Step-by-step explanation:
Use the foil method:
multiply 2x with 3x and -1.
then multiply -1 with 3x and -1
when multiplied, you should have gotten 2x×3x=6x^2, then 2x×-1, then -1×3x=-3x, then you put all of the answers in order from variables with exponents to normal variables to non variables
Write an equation in slope-intercept form of the line shown.
Answer:
y=2x-2
Step-by-step explanation:
The slope is 2 and your y intercept is already given as -2.
Slope intercept is basically y=mx+b
plug it in so you get y=2x-2
Please solve quickly 11-14
Answer:
Step-by-step explanation:
11). 6x + 3y = 9
3(2x + y) = 9
2x + y = 3
y = -2x + 3
Since variables are of single degree therefore, it's a linear function
12). 3y - 2x = -2x - 12
3y - 2x + 2x = -2x - 12 + 2x
3y = -12
y = -4
Since variable y is of single degree therefore its a linear function.
13). 11y + 4x = -8 + 11y
11y + 4x - 11y = -8 + 11y - 11y
4x = -8
x = -2
Linear function.
14). 4x - 3 + 2y = 8x - 9
4x + 2y - 3 - 4x = 8x - 4x - 9
2y - 3 = 4x - 9
2y = 4x - 9 + 3
2y = 4x - 6
y = 2x - 3
Linear function.
Answer this........Please
Answer:
x -22
Step-by-step explanation:
Sum = -7 (-22+15 = -7)
Product = -330 (-22*15 = -330)
Factors = -22 , 15
x² - 7x - 330 = x² +15x - 22x - 22 *15
= x(x + 15) -22(x + 15)
= (x +15)(x -22)
[tex]\frac{x^{2}-7x-330}{x + 15}=\frac{(x+15)(x-22)}{(x+15)}\\\\ =x - 22[/tex]
math question again plz help
answers are:
6, 8, 5, 11
If the perimeter is 3(2v-6)
Than
Pull out like factors : 2v - 6 = 2 • (v - 3)
Final result : 6 • (v - 3)
Given the result your answer would be 6.

Henry and his children went into a grocery store and where they sell peaches for $2 each and mangos for $1.25 each. Henry has $20 to spend and must buy no less than 10 peaches and mangos altogether. If Henry decided to buy 4 peaches, determine all possible values for the number of mangos that he could buy. Your answer should be a comma separated list of values. If there are no possible solutions, submit an empty answer.
Since 4 peaches x 2 =8, you would would only be able to buy 6 mangos since $1.25 x 6 mangos =$7.5 so it would be $7.5+$8=$15.5 and 6 mangos+4 peaches=10 in total. And he would also save $5.00! :)
Please mark brainliest!
Hope it helps!
what should be added to
11/21 to make it
19/21
To find what needs to be added subtract the two numbers:
19/21 - 11/21 = 8/21
You need to add 8/21 to 11/21 to get 19/21
Arthur is organising his collection of dvds he has 135 altogether. The ratio of comedy films to action horror is 6 : 8 : 1
Answer: See explanation
Step-by-step explanation:
The number of comedy films will be:
= 6/(6+8+1) × 135
= 6/15 × 135
= 54 comedy films
The number of action films will be:
= 8/(6+8+1) × 135
= 8/15 × 135
= 72 action films
The number of horror films will be:
= 1/(6+8+1) × 135
= 1/15 × 135
= 9 horror films

Joe works for a charity. Each year the charity gives money to different projects. The charity has a total of eight thousand nine hundred and sixty-eight pounds to give to the projects this year.
Answer:
[tex]Each =\pounds 1121[/tex]
Step-by-step explanation:
See comment for complete question.
Given
[tex]Total = \pounds 8968[/tex]
[tex]Projects = 8[/tex]
Required
Determine the amount allotted to each
From the question, we understand that each project gets each allocation.
So, the amount of each is:
