how can you solve 25% of 44 both mentally and with pencil and paper?
Answer:
Solving it mentally :-
It says 25% × 44. When we have a percent, change it to decimal and solve which would be easy to do it mentally.
25% = 0.25
0.25 × 44 = 11 *Answer is bolded.*
Solving it on paper :-
I have attached a picture of me doing it on paper.
Hope this helps, thank you :) !!
Using the common denominator of 56, what is an equivalent fraction for 3/8 and 3/7?
Answer: [tex]\frac{3}{8}[/tex]=[tex]\frac{21}{56}[/tex] [tex]\frac{3}{7}[/tex]=[tex]\frac{24}{56}[/tex]
Step-by-step explanation:
In order to get from 8 to 56, we have to multiply by 7.
We always do the same to the top! 3 multiplied by 7 = 21.
In order to get from 7 to 56, we have to multiply by 8.
We always do the same to the top! 3 multiplied by 8 = 24.

6. A survey was conducted by
asking 120 students in a town
how they traveled to school.
The following pie chart shows
the result of the survey.
What are the number of students
that travel to school by bus?
Best Answer gonna have branliest
Answer:
(a) Since, the highest central angle 120⁰ is of the bus
hence , the most common mode of transport is the bus.
(b) Fraction of children travelling by car =
angle covered by car section
--------------------------------------------
total angle
= 90⁰ 1
--------- = ---------
360⁰ 4
(c) No. of children travelling by car = Fraction of children travelling by car× Total no of children.
1
= 18 = ----- × Total no. of children.......from(b)
4
⇒ Total no of children = 18×4
⇒ Total no of children = 72
(d) Central angle of children who do not take texi = 120⁰ +90⁰ +60⁰+60⁰
⇒ Central angle of students who do not take taxi = 330⁰
⇒ Central angle of students who do take taxi = 360⁰ −330⁰ =30⁰
30⁰
No . of children travelling by taxi = --------- × Total no of children
360⁰
30⁰
⇒ No of children travelling by taxi = --------- × 72 = 6
360⁰
(e) The central angle for students travelling by cycle and those who walk is same.
Thus , the two modes of transport are equal number of children travelling are cycle and walk.

This is an isosceles right triangle.
The hypotenuse has a length of 1.
Find the length of each leg.
Answer:
Step-by-step explanation:
if we have a right triangle, and isosceles
c^2=a^2+b^2 , in this case of isosceles, a=b
c^2=2a^2
1^2=[tex]\sqrt{2a^2}[/tex]
1=a[tex]\sqrt{2}[/tex]

Please help me solve this
Answer:
x = 15
Step-by-step explanation:
we know that the total degree inside of a triangle made up of 180°
6x + 4x + 2x = 180
12x = 180
x = 15
To find each angle we multiple 4x , 6x, 2x by 15
4(15) = 60°
6(15) = 90°
2(15) = 30°
Answer:
soln,
2x+6x+4x=180°( being s of the angle of triangle is 180°)
12x=180°
X= 180°/12
X= 15
again,
2x=2×15. 6x= 6×15. 4x=4×15
2x=30. 6x=90. 4x=60

Simplify cot θ sec θ.
Answer:
csc θ
Step-by-step explanation:
cot θ sec θ can be substituted by reducing the expression into equivalent parts.
cot θ = (cos θ)/(sin θ)
sec θ = 1/(cos θ)
Reduce these two values to get 1/(sin θ)
This expression can then be changed to csc θ, as it is also equivalent.
The trigonometric expression cot θ × sec θ in the simplified form will be cosec θ.
What is trigonometry?Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The expression is given below.
⇒ cot θ × sec θ
We know that cot θ = cos θ / sin θ and sec θ = 1 / cos θ, then we have
⇒ cot θ × sec θ
⇒ cos θ / sin θ × 1 / cos θ
⇒ 1 / sin θ
We know that 1 / sin θ = cos θ
⇒ 1 / sin θ
⇒ cosec θ
The trigonometric expression cot θ × sec θ in the simplified form will be cosec θ.

m∠R=140 and m∠S=100. Find the m∠T. The diagram is not on the scale.
Answer:
m<T = 20°
Step-by-step explanation:
m<R = 140°
m<S = 100°
The figure given is a kite. The angles formed where two unequal sides meet are always congruent to each other. This means:
m<S = m<U = 100°
Sum of all interior angles of a quadrilateral = 360°
Therefore:
m<T = 360° - (m<S + m<U + m<R)
m<T = 360° - (100° + 100° + 140°) (substitution)
m<T = 20°
Noralie has a home-based business putting on children’s parties. She charges $45 to design the party and then $5.50 per child. Write a function rule that relates the total cost of the party to the number of children n.
f(n) = 5.5 – 55n
f(n) = 5.5n – 55
f(n) = 5.5 + 45n
f(n) = 45 + 5.5n
Answer:
The answer would be C because n is the number of children and it costs $5.50 per child plus an extra design fee of $45
Step-by-step explanation:
Design = $45
rate per child = $5.50
number of children, x
total cost, f(x) = $5.5x + $45

Renting a jet ski at Jerry's Water sports cost $20.00 per hour plus a one-time fee of $8.00. Renting jet skis from splash of fun costs $25.00 per hour with no one-time fee. the cost to rent a jet ski depends on the total number of hours, h, rented. How many hours must you rent a jet ski for the cost to be the same at jerry's water sport and at splash of fun?
Answer:
1.6 hours
Step-by-step explanation:
The computation of the number of hours is shown below:
For water sports
= 20x + 8
And,For splash of fun
= 25x
Now the cost of both would be same
i.e.
20x + 8 = 25x
8 = 5x
x = 1.6 hours

5 Clear 1 Petrov ran 7 laps around a track. Each lap around the track is a distance of mile. What is the total distance Petrov ran in feet? A 9,240 ft 3,017 ft 1,327 ft 36,960 ft
Answer: 36,960 ft
Step-by-step explanation:
Each lap around the track was a mile in distance.
Petrov therefore ran a total of 7 miles.
A mile is 5,280 feet.
If Petrov ran 7 miles in total, this distance in feet is:
= 7 * 5,280
= 36,960 ft
Solve these simultaneous equations: 3x = y and x = y - 16
Answer:
x=8
y=24
Step-by-step explanation:
3x=y
x=y-16
Substitute y for 3x
x=3x-16
Add 16 to each side
x+16=3x
Subtract x
16=2x
Divide each side by 2
8=x
y=3x=3×8=24
y=24
Here we have been given with two equations and we have to calculate the values of x and y. So we would be using substitution method for it.
3x = y (Equation No 1)x = y - 16 (Equation No 2)Here we can clearly see that value of y is 3x. So we would substitute it in Equation No 2.
>> x = y - 16
>> x = 3x - 16
>> x - 3x = -16
>> -2x = -16
>> 2x = 16
>> x = 16 / 2
>> x = 8
★ Finding out value of y:-
>> y = 3x
>> y = 3 (8)
>> y = 3 × 8
>> y = 24 [tex] \: [/tex]

Answer:
1) Zero based on (-16·t - 2) is t = -1/8 second
2) Zero based on (t - 1) is t = 1 second
Step-by-step explanation:
The given functions representing the height of the beach ball the child throws as a function of time are;
y = (-16·t - 2)·(t - 1) and y = -16·t² + 14·t + 2
We note that (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
Therefore, the function representing the height of the beachball, 'y', is y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
The zeros of a function are the values of the variables, 'x', of the function that makes the value of the function, f(x), equal to zero
In the function of the question, we have;
y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
The above equation can be written as follows;
y = (-16·t - 2) × (t - 1)
Therefore, 'y' equals zero when either (-16·t - 2) = 0 or (t - 1) = 0
1) The zero based on (-16·t - 2) = 0, is given as follows;
(-16·t - 2) = 0
∴ t = 2/(-16) = -1/8
t = -1/8 second
The zero based on (-16·t - 2) is t = -1/8 second
2) The zero based on (t - 1) = 0, is given as follows;
(t - 1) = 0
∴ t = 1 second
The zero based on (t - 1) is t = 1 second
