Answer:
The perimeter is 127.1 cm
Step-by-step explanation:
30+25+25=80
(2)(3.14)(15)=94.2
94.2/2=47.1
Divide by two because of the semicircle
80+47.1=127.1
Answer:
Step-by-step explanation:
do this in two parts. one, the rectangle, two, the circle
the rectangle , you only have 3 sides to the rectangle.
2 * 25 = 50
1* 30 = 30
total perimeter of the rectangle = 80 cm
the circle, find the total of the circle, then since there is only half and circle, multiply that by 1/2 or divide by 2, same thing.
perimeter of a circle is the circumference
circumference of a circle is 2[tex]\pi[/tex]r or diameter[tex]\pi[/tex] , same thing
30[tex]\pi[/tex] = 94.24777961 cm ( the whole circle )
1/2*94.24777961 =47.1238898 cm
add the two parts
80 + 47.1238898 = 127.1238898 cm
127.12 cm ( rounded to two decimal places )

Mayra bought a pair of sneakers. They originally cost $75 but were on sale for 15% how much mony did she save
Answer: $11.25
Step-by-step explanation:
Since the sneakers were on sale for 15% less, the amount she bought them will be:
= (100% - 15%) × $75
= 85% × $75
= 0.85 × $75
= $63.75
Therefore, the amount she saved will then be:
= $75 - $63.75
= $11.25
She saved $11.25

4 cans of orange juice and 7 cans of apple juice are in a sports bags what is the probability of drawing out one can of apple juice without looking? write your answer as a decimal rounded to two decimal places.
Answer:
1.36
total cans =11
the prob. of drawing orange juice can= 4/11
the prob of drawing apple juice can= 7/11
the prob of drawing any of the juice= 4/11 + 7/11
= 15/11
= 1.36
Sin0=20/29 find tan 0
Answer:
Step-by-step explanation:
here opposite =20, hypotenuse=29
to find adjacent use formula
a^2+b^2=c^2
20^2+b^2=29^2
400+b^2=841
b^2=841-400
b=[tex]\sqrt{441\\}[/tex]
b=21
tan theta=opposite/adjacent
=20/21
therefore tan theta =20/21
Answer:
D. tanθ = 20/21
Step-by-step explanation:
Remember that sinθ = opposite/hypotenuse. In this case, since sinθ = 20/29, we are going to say that opposite = 20 and hypotenuse = 29.
To solve for the adjacent side, use the Pythagorean theorem, a^2 + b^2 = c^2.
When you plug in your values and solve for the other leg, you'll get 21.
Now that we know that the adjacent side/other leg is equal to 21, we can find tanθ, since it's equal to opposite/adjacent.
Opposite = 20
Adjacent = 21
tanθ = 20/21

find the slope between (-3,2) and (-7,-16)
Answer: The slope between these two is 3.5
Answer:
Solpe=4.5
Step-by-step explanation:
Sorry if I’m wrong, but I think I got it.
So the formula for slope is y2-y1/x2-x1
In (-3,-2) )-7,-16), -3 is x1, -2 is y1, -7 is x2, and -16 is y2.
Now, you need to fill in the formula with these numbers.
-16-2/-7- - 3
-16-2 is -18
-7- - 3 is -4 (two negatives make a positive)
This makes -18/-4. Divide this to get 4.5.
Let me know if you have any questions!! :)

Factor the expression 36a4b10 81a16b20 using the two different techniques listed for Parts 1(a) and 1(b). (a) Factor the given expression using the GCF monomial. (a) Factor the given expression using the GCF monomial. (b) Factor the given expression using the difference of squares.
Answer:
The answer is "[tex]9a^4b^{10}(2+6a^6b^5)(2-6a^6b^5)[/tex]"
Step-by-step explanation:
For point a:
[tex]36a^4b^{10} - 81a^{16}b^{20}[/tex] by GCF
Calculating the const terms:[tex]36 \ n \ 81, \ GCF \ is\ 9\times 4 \ n \ 9\times 9[/tex]
Calculating the terms [tex]w\ a: a^4 \ n \ a^{16},\ GCF \ is\ a^4 \ n \ a^4 \times \ a^{12}[/tex]
Calculating the terms [tex]w \ b: b^{10}\ n\ b^{20}, \ GCF \ is\ b^{10}\ n \ b^{10} \times b^{10}[/tex]
Including the GCFs, [tex]36a^4 b^{10} - 81a^{16}b^{20}[/tex]
[tex]=9a^4b^{10}(4 - 9a^{12}b^{10})\\\\4=2^2 n 9a^{12}b^{10}\\\\=(3a^6b^5)^2[/tex]
Calculating the difference of squares
[tex]\to A^2 - B^2 = (A+B)(A-B)\\\\\to 4 - 9a^{12}b^{10} \\\\\to (2+3a^6b^5)(2-3a^6b^5)\\\\[/tex]
substituting
[tex]\to 36a^4b^{10} - 81a^{16}b^{20}\\\\\to 9a^4b^{10}(2+3a^6b^5)(2-3a^6b^5)[/tex]
For point b:
Calculating the difference of squares:
[tex]A^2 - B^2 = (A+B)(A-B)\\\\36a^4b^{10}=(6a^2b^5)^2\\\\81a^{16}b^{20}=(9a^8b^{10})^2\\\\36a^4b^{10} - 81a^{16}b^{20}\\\\=(6a^2b^5+9a^8b^{10})(6a^2b^5-9a^8b^{10})\\\\=3a^2b^5(2+6a^6b^5)3a^2b^5(2-6a^6b^5)\\\\=9a^4b^{10}(2+6a^6b^5)(2-6a^6b^5)[/tex]
The perimeter of a certain square is 4 yards. Find the area of the square in square feet.
Please someone help
Step-by-step explanation:
Write what you know
A square has 4 sides
the perimeter is the sum of the length of all 4 sides
so 4yards / 4 sides = 1 yard per side
we also know a square has all equal sides
that means our area formula will be 1 x 1
Jim was thinking of a number. Jim doubles it, then adds 19 to get an answer of 70.1. What was the original number?
Answer:
25.55
Step-by-step explanation:
Let us take the number he thinked of be x .
On doubling it :-
→ N = 2x
On adding 19 :-
→ N = 2x + 19
According to Question :-
→ 2x + 19 = 70.1
→ 2x = 70.1 - 19
→ 2x = 51.1
→ x = 51.1/2
→ x = 25.55
