Rs. 52[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given parameters:
Amount spent on buying a food = Rs. 25.75
Amount spend on buying pen = Rs. 10.25
Amount given out to friend = Rs. 16.5
Unknown:
The total money he initially had = ?
Solution:
The total money he initially had :
= amount spent on food + amount spent on pen + amount given to friend
= Rs. 25.75 + Rs. 10.25 + Rs. 16.5
= Rs. 52.5 or Rs. 52[tex]\frac{1}{2}[/tex]

The sum of two numbers is 91. The greater number is 7 more than the smaller number. Which equation can be used to solve for the smaller number?
x(x + 7) = 91
x(x − 7) = 91
x + (x + 7) = 91
x − (x + 7) = 91
Answer:
x+(x+7)=91

Answer: your answer for the smaller number is 38.5 and the larger number is 52.5.
Step-by-step explanation:
To make sure it's right, I just add the numbers together.
Your Problem:
91 ÷ 2 = 45.5
45.5 + 7 = 52.5
45.5 - 7 = 38.5
52.5 + 38.5 = 91

After 22 games, JD Drew has 32 hits. After 36 games he has 60 hits. Write a linear equation in slope intercept form to describe the situation. How many hits with JD Drew have after 50 games
Answer:
JD Drew will have 88 hits after 50 games
Step-by-step explanation:
Linear Modeling
It consists of modeling real-life situations by a function whose graph is a straight line.
The equation of a line can be expressed as:
h=m.g+b
h=number of hits JD Drew has
g=number of games
m,b= constant values
The problem provides two conditions: after 22 games, JD Drew has 32 hits. This is the point (22,32). Also, it has been given after 36 games he has 60 hits. This is the point (36,60).
Substituting the ordered pairs given, we have:
32=m.22+b
60=m.36+b
Subtracting both equations:
60 - 32 = 14m
28 = 14m
Solving:
m = 2
Using the first equation:
32 = (2)*22+b
32 = 44 + b
Solving:
b = -12
The model is now complete:
h = 2g - 12
Finally, calculate the number of hits for g=50 games:
h = 2*50 - 12
h = 100 - 12 = 88
JD Drew will have 88 hits after 50 games

Maria needs 23 ounces of water and 57 gallons of milk. The cost of the milk is $9.20 per gallon and the cost of the water bottles is $2.99. If The water is supposed to be measured in ounces how many ounces is the milk going to be measured in and how much would it cost,
Given :
Maria needs 23 ounces of water and 57 gallons of milk.
The cost of the milk is $9.20 per gallon and the cost of the water bottles is $2.99.
To Find :
How many ounces is the milk going to be measured in and how much would it cost.
Solution :
We know, 1 gallon = 128 ounces.
So, 57 gallon of milk = 57×128 = 7296 ounces.
Cost of 1 gallon milk = $9.20 .
So, cost of 57 gallon is = 57×9.20 = $524.4
Therefore, volume in ounces is 7296 and cost is $524.4 .
Hence, this is the required solution.
What is the only real number which, when divided by itself, is 2020
times itself?
Answer:
1/2020
Step-by-step explanation:
We can set up an equation, where x is the number that, when divided by itself, is 2020 times itself:
x/x = 2020*x
The left-hand side reduces to 1:
1 = 2020*x
Now, you can divide both sides by 2020:
x = 1/2020
To check, we can divide 1/2020 by itself:
[tex]\frac{\frac{1}{2020}} {\frac{1}{2020}} = \frac{1}{2020}\cdot \frac{2020}{1} = \frac{2020}{2020} = 1[/tex]
1 is indeed 2020 times 1/2020.
We have that
x=4.95*10^{-4}
From the question we are told
What is the only real number which, when divided by itself, is 2020
times itself
Generally the equation for the statement is mathematically given as
[tex]\frac{x}{x}=2020*x\\\\1=2020*x\\\\x=\frac{1}{2020}\\\\x=4.95*10^{-4}[/tex]
Hence
the only real number which, when divided by itself, is 2020
times itself is
[tex]x=4.95*10^{-4}[/tex]

State whether the given measurements determine zero, one, or two triangles.
A = 61°, a = 23, b = 24
Answer:
One
Step-by-step explanation:
Find the value of B
Applying the law of sines
[tex]\frac{a}{sin(A)}[/tex] = [tex]\frac{b}{sin(B)}[/tex]
substitute the given values
[tex]\frac{23}{sin(61)}[/tex] = [tex]\frac{24}{sin(B)}[/tex]
sin (B) = [tex]\frac{24}{23}[/tex]Sin(61)
step 2
Find the measure of angle C
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
61 + 65.87 + C = 180
C = 53.13
step 3
Find the value of c
Applying the law of sines
[tex]\frac{a}{sin(A)}[/tex] = [tex]\frac{c}{sin(C)}[/tex]
substitute the given values
[tex]\frac{23}{sin(61)}[/tex] = [tex]\frac{c}{sin(53.13)}[/tex]
c = [tex]\frac{23}{sin(61)}[/tex]SIN (53.13)
C=21.04 units
so
there can only be one value for each measurement, therefore there can only be one triangle

The items Pedro has selected at his local hardware store have a total cost of $130 before tax. If the sales tax is 8.25%, which is closest to the amount of sales tax Pedro can
expect to pay?
Answer: $10.7
Step-by-step explanation:
The following can be deduced from the question:
Total cost of items = $130
Percentage of Sales tax = 8.25%
Sales tax = Sales tax percent × Cost
Sales tax = 8.25% × $130
Sales tax = 8.25/100 × $130
= 0.0825 × $130
= $10.725
= $10.7
A conveyor belt moves at a constant rate of 12 feet in 3 seconds. A second conveyor belt moves at a constant rate of 21 in 7 seconds. Does this situation represent a proportional relationship?
Answer:
No.
Step-by-step explanation: If we look at the first conveyor belt, the rate is 12ft in 3 seconds, or 4 feet a second. The second conveyor belt moves at 21 feet in 7 seconds, or 3 feet a second. Since the two values are unequal, we can conclude it is not a proportional relationship.

A parabola has its axis of symmetry at x = -2 and passes through the point (-5, 6). Find another point that passes through the parabola.
Answer:
(1,6)
Step-by-step explanation:
Since the parabola is symmetrical at x=-2, we know that if you take the value for (x-a) and (x+a) where a is any constant, the y values will be the same for both of those x coordinates. so, we can take the coordinate that we know, (-5,6), realize that it is -3 away from -2. then we can add three to get 1 and use the same y coordinate, getting (1,6)
What is the solution set of the equation below? 3|5 − x| + 2 = 29
Answer:
x=-4
x=14
Step-by-step explanation:
Absolute Value Equation entered :
3|5-x|+2=29
Step by step solution :
STEP
1
:
Rearrange this Absolute Value Equation
Absolute value equalitiy entered
3|-x+5|+2 = 29
Another term is moved / added to the right hand side.
3|-x+5| = 27
STEP
2
:
Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is 3|-x+5|
For the Negative case we'll use -3(-x+5)
For the Positive case we'll use 3(-x+5)
STEP
3
:
Solve the Negative Case
-3(-x+5) = 27
Multiply
3x-15 = 27
Rearrange and Add up
3x = 42
Divide both sides by 3
x = 14
STEP
4
:
Solve the Positive Case
3(-x+5) = 27
Multiply
-3x+15 = 27
Rearrange and Add up
-3x = 12
Divide both sides by 3
-x = 4
Multiply both sides by (-1)
x = -4
Which is the solution for the Positive Case

A fishing boat with two people on it runs out of gas while out in a bay. The people set off an emergency flare from a height of 2 meters above the water. The flare has an initial vertical velocity og 30 meters per second. How long does it take the flare to reach its maximum height? What is that height?
Answer:
Step-by-step explanation:
time taken to reach the max height is expressed according to the projectile equation;
tmax = u/g
Given u = 30m/s
g is the acceleration due to gravity = 9.81
t = 30/9.81
t = 3.0secs
hence it will take the flare 3.06secs to reach its maximum height.
Max height = u²/2g
Max height = 30²/2(9.81)
Max height = 900/19.62
Max height = 45.87m
If the people set off an emergency flare from a height of 2 meters above the water, the total height will be 45.87 + 2 = 47.87m

<B = 90-44 = 46
A and C must be equal
A + B + C = 180

nickles, how many dimes (d) does she have?
A. 0.10d + 7(0.25) + 7(0.5) = 2.70 ; d = -25.5
B. 0.10d + 7(0.25) + 0.05 = 2.70 ; d = 9
C. 10d +7(25 + 5) = 2.70 ; d = 20
D. 0.10d + 7(0.25 + 0.05) = 2.70 ; d = 6
Answer:
Step-by-step explanation:
0.25×7+0.05×7+0.10d=2.70
7(0.25+0.05)+0.10d=2.70
7(0.30)+0.10d=2.70
2.10+0.10d=2.70
0.10d=2.70-2.10
0.10d=0.60
d=0.60/0.10=6
Hence D

Please consider Brainliest :)
x = 10
All you have to do is add 15 to both sides, and you have
30 =3x
and divide by 3
