Answer:
De acuerdo a la información proporcionada, dado que se van a repartir 5 barritas entre 8 niños, se tiene que dividir las barritas entre el número de niños y a partir de aquí, se construye la fracción 5/8. Esto lo que indica es que cada barrita se divide en ocho pedazos y cada niño recibiría 1/8 de cada barrita y para las 5 barritas sería:
1/8*5=5/8
what is x -2(4x-3)=-12-14x
Answer:
x= -17/8
Step-by-step explanation:
1 step: take care of the parentheses ( multiply -2 to what is on parentheses)
so x -8x +6 =-12-14x
2 step : move all number with x to the left side
x-8x +14x = -12 -6
7x = -18
x = -18/7
hey! can u help me with this?! 6 divided by 3/5 in fraction form!?!?!!?
Answer:
10/1
Step-by-step explanation:
You do
6÷ 3/5
Flip the 3/5 then multiply
6 ° 5/3
Reduce the numbers with the greatest common factor 3
So 2•5
And that's 10
Ans is 10.
The numbers in 6 divided by 3/5 are labeled below:
6 = whole number
3 = numerator
5 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
6 x 5/3 = 30/3
Thus, the answer to 6 divided by 3/5 in fraction form is:
30/3
To make the answer to 6 divided by 3/5 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
30 / 3 = 10
The answer is rounded to the nearest two decimal points if necessary.
30/3 can be simplified to 10/1.
10/1 is an improper fraction and should be written as 10.
Give step by step instructions and the final answer on how to find the volume of a right square pyramid who has a slant height of 5 inches and the length of the base is 4 inches.
To earn full points you must :
- Show each step of your work
- Keep it organized and easy to read
- Give a brief explanation of why you perform each step
- give the correct final answer
Answer:
Below.
Step-by-step explanation:
First find the perpendicular height of the pyramid.
The median of one of the faces, the height and and half the length of the square base make a right triangle with base 2 and hypotenuse 5, so using the Pythagoras theorem:
5^2 = 2^2 + h^2
h^2 = 5^2 - 2^2 = 21
h = √21 inches.
The volume of the pyramid V = 1/3 * h * area of the base, so
V = 1/3 * 4^2 * √21
= 24.44 in^3 to nearest hundredth.
The volume of a right square pyramid will be (16√21) / 3 cubic units.
What is the volume of the pyramid?Let h be the height of the pyramid, l be the slant height and A be the base area of the pyramid.
Then the volume of the pyramid will be
Volume = (1/3) × A × h
The slant height is given as.
l² = (half of side)² + h²
A right square pyramid has a slant height of 5 inches and the length of the base is 4 inches.
Then the height of the pyramid will be
5² = (4/2)² + h²
h² = 25 - 4
h = √21 inches
Then the volume of a right square pyramid will be
Volume = (1/3) × 4 × 4 × √21
Volume = (16√21) / 3
Thus, the volume of a right square pyramid will be (16√21) / 3 cubic units.
More about the volume of the pyramid link is given below.

5 Mario has $660 in his savings account earning 2.5% interest yearly. How much interest will he earn in 2 years?
Im terrible at word problems smh
Answer:
$33
Step-by-step explanation:
You do $660 • 0.025
You have to bring the decimal two places to the left for finding the decimal point.
So you'd get 16.5.
But there's two years. So times it by two.
So it's 33.

The time of the latest bus that Jo can catch from the Bus Station is 07 00.
The time the bus takes to travel from the bus station to School Road is 14 minutes.
How to find the time ?The table shows that when a bus leaves for School Road from Hope Street, at 07 54, it will arrive on School Road at 08 04.
The time it takes from the bus station to School road is:
= Arrival time at school road - Departure time from Bus station

Suppose that 29\%29%29, percent of undergraduates at a large university are involved in a campus organization. The administration plans to take an SRS of 100100100 undergraduates from the population of over 20{,}00020,00020, comma, 000 undergraduate students at the school to see what proportion of students sampled are involved in a campus organization.
Answer:
μ p ^ =0.29
σ p ^ = Square root[ ( (0.29)(0.71) )/100 ]
Step-by-step explanation:
The mean of the sampling distribution of a sample proportion is equal to the population proportion.
μ p ^ =p
The population proportion reported is 29%, so p=0.29p.
\mu_{\hat p}=p=0.29μ
μ p ^ = 0.29
Since σ p hat = sqare root [ ( p(1-p) )/ n]
After subsitution we get σ p ^ = Square root[ ( (0.29)(0.71) )/100 ]

PLS HELP ME IM AWARDING BRAINLIEST!
Answer:
First option: 336
Step-by-step explanation:
To find the answer, separately solve for each of the shapes.
1. The base is the square so length times width is the formula:
12 x 12 = 144
144 is the area of the square
Next, find the 4 triangles which are congruent(the same).
Triangle area formula: Base x Height divided by 2.
So, the area of 1 triangle is 12 x 8 =96
96/2 = 48
Area =48
Because there are 4 triangles, do 48 x 4=192.
Finally, add the area together and you should get 192+144 =336 ft^2
Surface area = 336 ft^2

If side x has a length of 15 cm and side y has a length of 4 cm, then which value below could be the length of side z?
A.
20 cm
B.
21 cm
C.
17 cm
D.
10 cm
Given:
In a triangle, side x has a length of 15 cm and side y has a length of 4 cm.
To find:
The possible value of side z.
Solution:
In a triangle, the sum of two smaller sides must be greater than the largest side otherwise the triangle is not possible.
Case I: Let x be the largest side, then
[tex]y+z>x[/tex]
[tex]4+z>15[/tex]
[tex]z>15-4[/tex]
[tex]z>11[/tex] ...(i)
It is clear that [tex]y<x[/tex]. So, y cannot be a largest side.
Case II: Let z be the largest side, then
[tex]x+y>z[/tex]
[tex]15+4>z[/tex]
[tex]19>z[/tex] ...(ii)
From (i) and (ii), we get
[tex]11<z<19[/tex]
It means the value of z lies between 11 and 19.
From the given options, only 17 is the value which lies between 11 and 19. So, the possible length of side z is 17 cm.
Therefore, the correct option is C.

We know that 6z-31+something is going to be equal to 180 degrees, because it is supplementary. But what is that something? We see 67 degrees. Do you think this is a corresponding angle to the something that we need to find? Yes, it is! So we know that 6z-31+67 is equal to 180. So, z is 24. Now, since we know the value of the something (67 degrees because of corresponding angles) we can find yet another pair of supplementary angles. 67+x=180! Kind of neat, huh? So, x is equal to 113.

Terry uses a ladder that is 12 feet tall. To be safe the ladder must make an angle of elevation of between 70-85 degrees to be safe. If he places the ladder 3 feet from the wall, is it safe?
Answer:
It is safe
Step-by-step explanation:
Using trigonometry :
Cosθ = adjacent / hypotenus
Hypotenus = length of ladder = 12 feets
Adjacent = distance between ladder and wall = 3 feets
Cosθ = 3 /12
Cosθ = 0.25
θ = cos^-1(0.25)
θ = 75.522°
To be safe ladder must be between (70 - 85)°
Sijce ladder is at an elevation of 75.22° ; then it is safe.

Here are the marks of a student in four exams.
65 80 76 69
The student takes a fifth exam.
His mean mark for the five exams is 70
Work out his mark in the fifth exam.
Answer:
61 marksStep-by-step explanation:
Given,
Marks of the four exams = 65, 80, 76, 68
Let the mark for the fifth exam be = x
Mean of the five exams = 70
Therefore,
By the problem,
[tex] = > \frac{65 + 80 + 76 + 68 + x}{5} = 70[/tex]
[tex] = > \frac{289 + x}{5} = 70[/tex]
=> 289 + x = 70 × 5
=> 289 + x = 350
=> x = 350 - 289
=> x = 61
Hence,
Marks of the fifth exam is 61 (Ans)
