31=x/3+10
Answer:
403
Step-by-step explanation:
31 = x/3 + 10
31 = (x + 30)/3
93 = x + 30
x = 93 - 30
x = 63
4x + 3y = 1
12x– 9y=4
Answer:
x = 7/24 y = -1/18
Step-by-step explanation:
3y = -4x + 1
y = (-4/3)x + (1/3)
*plug into the other equation
12x - 9(-4/3x + 1/3) = 4
12x + 12x - 3 = 4
24x = 7
x = 7/24
*now plug into original equation
y = (-4/3)(7/24) + 1/3
y = -1/18

Round the numbers to estimate the quotient. 29 and one-fifth divided by 4 and StartFraction 6 over 7 EndFraction Which numbers should be used? 25 ÷ 5 The estimated quotient is
Answer:
The quotient is 6.
Step-by-step explanation:
Given two fractions are:
[tex]29\dfrac{1}{5}[/tex]
and
[tex]4\dfrac{6}7[/tex]
To find:
The quotient of
[tex]29\dfrac{1}{5}\div 4\dfrac{6}7[/tex]
Solution:
Formula to convert mixed fraction to a fraction:
[tex]p\dfrac{q}{r} = \dfrac{p\times r+q}{r}[/tex]
Using the above formula to rewrite the given mixed fractions:
[tex]29\dfrac{1}{5}[/tex] can be written as:
[tex]\dfrac{29\times 5+1}5\\\Rightarrow \dfrac{146}{5}[/tex]
[tex]4\dfrac{6}7[/tex] can be written as:
[tex]\dfrac{4\times 7+6}{7}\\\Rightarrow \dfrac{34}{7}[/tex]
Now dividing:
[tex]\dfrac{\frac{146}{5}}{\frac{34}{7}}\\\Rightarrow \dfrac{146\times 7}{5\times 34}\\\Rightarrow \approx 6[/tex]
Therefore the quotient is 6.

The mass of a baby elephant is 113 kg, and it walks at a constant velocity of 0.5 m/sec. What is the kinetic energy for the baby elephant?
Answer:
Step-by-step explanation:
K.E. = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]
So,
=1/2 x 113 x 0.5 x 0.5
=1/2 x 1/2 x 1/2 x 113 (Because, 0.5 = 1/2)
=1/8 x 113
= 14.125 J
Using the kinetic energy formula, the kinetic energy of the baby elephant is 14.125 joules
Given the Parameters :
Velocity, v = 0.5 m/secMass, m = 113 kgRecall :
Kinetic energy = 0.5mv²The kinetic energy of the baby elephant can be calculated thus :
Kinetic energy = 0.5 × 113 × 0.5² = 14.125 Joules
Therefore, the kinetic energy of the baby elephant is 14.125J

Every month the library hosts a family movie night. This month, 50 people attended the movie night. This was two more than three-fourths of the total number of people who attended the movie night last month. Write and solve an equation to determine how many people attended last month's family movie night. Use x as the variable.
Answer:
64 people
Step-by-step explanation:
Let the number of people that attended the movie last month be represented by x.
Number of people who attended the movie this month = 50
[tex]\frac{3}{4}[/tex] of x + 2 = 50
[tex]\frac{3x}{4}[/tex] + 2 = 50
[tex]\frac{3x}{4}[/tex] = 50 - 2
[tex]\frac{3x}{4}[/tex] = 48
3x = 48 x 4
3x = 192
x = 64
The number of people that attended the movie last month was 64.

Radius of tire (r) = 30 cm
Number of complete rotations made = 3
To start with :
Obtain the Circumference : 2πr
Hence,
Circumference = 2 * π * r
= 2 * π * 30 = 6

Please help! I’ll give brainliest to whoever answers first!
Answer:
x = 16 y = 22.627 (or 16[tex]\sqrt{2[/tex])
Step-by-step explanation:
cos(45) = 16/y
y = 16/cos(45)
y = 22.627
tan(45) = 16/x
x = 16/tan(45)
x = 16
*this can also be found because we know this is a right triangle with two angles of 45 degrees. This means that both sides will be equal so x will be 16 and the diagonal will be 16 root 2 (22.627)

Write a quadratic function with zeros -1 and 5.
Answer:
[tex]x^2+4x-5[/tex]
Step-by-step explanation:
Zeros of a quadratic equation are -1 and 5.
Sum of zeros = -1 + 5 = 4
Product of zeros = (-1)(5) = -5
The quadratic equation will be :
[tex]x^2+(\text{sum of zeros})x+\text{product of zeros}\\\\=x^2+4x-5[/tex]
So, the required quadratic equation is [tex]x^2+4x-5[/tex].
Daisy's Flowers sell a rose bouquet for $39.95 plus $2.95 for every rose. A competing florist sells a similar bouquet for $26.00 plus $4.50 for every rose. Find the number of roses that would make both florists' bouquets cost the same price.
Answer:
9 rosesStep-by-step explanation:
Step one:
given data
For Daisy's Flowers
the cost is $39.95
an additional $2.95 for every rose
let the number of rose be x
the linear model for the cost is
y=39.95+2.95x-----------1
Step two
For the competing florist
the cost is $26
an additional $4.5 for every rose
let the number of rose be x
the linear model for the cost is
y=26+4.5x------------2
Step three:
equating the two above equations to find the number of roses x
we have
39.95+2.95x=26+4.5x
solve for x
39.95-26=4.5x-2.95x
13.95=1.55x
divide both sides by 1.55
x=13.95/1.55
x=9
Hence the number of roses that would make both florists' bouquets cost the same price is 9 roses
1. A fish is 12 meters below the surface of the ocean. What is its elevation? meters 2. A sea bird is 28 meters above the surface of the ocean. What is its elevation? meters 3. If the bird is directly above the fish, how far apart are they? meters
Answer:
- 12 meters
28 meters
40 meters
Step-by-step explanation:
Given that:
A fish is 12 meters below the surface of the ocean. What is its elevation?
Position of fish = 12 meters below the surface = - 12 ;
Sea level = 0
Elevation = sea level + position
Elevation = 0 + (- 12)
= - 12 meters
2. A sea bird is 28 meters above the surface of the ocean. What is its elevation?
Position of bird = 28 meters below the surface = (28) ;
Sea level = 0
Elevation = sea level + position
Elevation = 0 + 28
= 28 meters
3. If the bird is directly above the fish, how far apart are they?
If bird is directly above the fish;
Distance between bird and fish :
Elevation of bird - elevation of fish
28 - (-12)
28 + 12
= 40 Meters
