Answer:
F=ma
We need an acceleration to calculate a force. For now, we can only say that F = 2.5kg*a
Step-by-step explanation:
Mass alone tells us nothing about any forces on the object. 2.5kg is the same whether in space or next to a black hole. The forces would be quite different, however.
11. If 1 is subtracted from the numerator and from
the denominator of a fraction, the value obtained
1
is z. If 1 is added to its numerator and to its
denominator, the resulting value is Ž. Find the
fraction.
Answer:
3/5
Step-by-step explanation:
Let x be the numerator
Let y be the denominator
1st equation:
(x-1) / (y-1) = 1/2
By simplifying the equation, 2(x-1) = y-1
y = 2(x-1) + 1
2nd equation:
(x+1) / (y+1) = 2/3
By simplifying the equation, 3(x+1) = 2(y+1)
3x + 3 = 2y + 2
2y = 3x + 1
y = (3x + 1) / 2
Substituting the value of y from the 1st equation to the 2nd equation:
1st equation: y = 2(x-1) + 1
2nd equation: y = (3x + 1) / 2
2(x-1) + 1 = (3x+1) / 2
x = 3
After finding the value of x, let's find y using the 2nd equation:
y = (3x + 1) / 2
y = [(3)(3) + 1] / 2
y = 5
Alternatively, we may also find the value of x using the first equation, and the result is still the same:
y = 2(x-1) + 1
y = 2(3-1) + 1
y = 5
CHECKING TIME!!!
Substituting the values of x and y:
Let x be the numerator, x = 3
Let y be the denominator, y = 5
1st equation: (x-1) / (y-1) = 1/2
(3-1) / (5-1) = 1/2
2/4 = 1/2
By simplification, 1/2 = 1/2
2nd equation:
(x+1) / (y+1) = 2/3
(3+1) / (5+1) = 2/3
4/6 = 2/3
By simplification, 2/3 = 2/3

Answer:
h(-4) = -1
h(-1) = -1
h(0) = 2
Step-by-step explanation:
h(-4) = -1 because -4<-1 and from the instructions if x < -1, it is -1
h(-1) = -1 because -1 = -1
h(0) = 2 because if 1<x<2 than we have to solute this -(x-1)^2 + 3
in this we have to replace x with 0
-(0-1)^2 + 3= -(-1)^2 + 3 = -1 +3 = 2

Krishnan had $10.he bought box of crayons and a pen. A box of crayons cost twice as much as a pen. He received $4 change.how much did the pen cost?
The cost of the Crayons will be $4 and the cost of the Pen will be $2.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Krishnan had $10. He had to purchase a box of pastels and a pen. A case of pastels costs two times as much as a pen. He got a $4 change.
Let c be the cost of crayons and p be the cost of a pen. Then the equations are given as,
c = 2p ...1
c + p = 10 - 4 ...2
From equations 1 and 2, then we have
2p + p = 10 - 4
3p = 6
p = 2
Then the cost of the crayons will be given as,
c = 2 x 2
c = 4
The cost of the Crayons will be $4 and the cost of the Pen will be $2.

At the grocery store 2/5 of a pound of grapes cost $2. What is the price per pound of grapes?
Answer:
$5 per pound of grapes
Step-by-step explanation:
Because 2/5 a pound of grapes cost $2 you would add another $2 for 4/5 pound of grapes. Then, you would divide 2 by 1/2 to get $1.
So 1 pound of grapes = $5

What is arithmetic operations?A number juggling activity is determined by consolidating operands with one math administrator. The built-in functions ADD, SUBTRACT, DIVIDE, and MULTIPLY can also be used to specify arithmetic operations.
Both the plus sign and the minus sign can be used as operators with prefixes or infixes. Only infix operators can be used to represent all other arithmetic operators.
Given cost of 2/5 pound of grapes is $2
2/5p = 2
where p = pound
p = (2 x 5)/2
1p = 5
1 pound = $5
Therefore the 1 pound of grapes cost $5.

Answer: [tex]7\sqrt{2[/tex]
Step-by-step explanation:

7²+7²=c²
49+49=c²
[tex]\sqrt{98}=\sqrt{c^2}\\\sqrt {49}\sqrt{2} =c\\ 7\sqrt{2} =c[/tex]
Answer:
7[tex]\sqrt{2}[/tex]
Step-by-step explanation:
To find the missing length of a right triangle use the Pythagorean theorem. This theorem is [tex]a^2+b^2=c^2[/tex]. The variables a and b are the legs (shorter sides) and c is the hypotenuse (longest side). In this case, the hypotenuse is the missing side. So, add and square 7. This looks like [tex]7^2+7^2=x^2[/tex]. So, [tex]98=x^2[/tex]. Finally, square root 98 to get the final answer, [tex]\sqrt{98}[/tex]. This can be simplified to [tex]7\sqrt{2}[/tex].
Additionally, this is a special right triangle because the legs are of equal length. If the legs are equal then the hypotenuse with be equal to x[tex]\sqrt{2}[/tex], where x is the length of the legs. So this problem can also be solved using this method.

there are 500 children in a school for the PT drill they have to stand in such a manner that the number of rows is equal to the number of columns.how many children would be left out in this arangement
Answer:
16 children would be left out in this arrangement
Step-by-step explanation:
Total number of children in a school = 500
For P.T. Drill number of rows = number of columns =x
The number of children who will be left out = 500−x^2 .
The square root of 500 gives remainder as 16 that means, the square of 22 is less than 500 by 16
To make it a perfect square = 500−16=484 Therefore, number of children left will be 16
= 16 children would be left out in this arrangement

Maia was baking cupcakes for a party. She mixed 4 drops of red food coloring for every 6 drops of yellow food coloring to dye her icing orange. Circle the ratios of food coloring drops that would create the same orange color and justify your choices
Choice 1: 2 red to 3 yellow
Choice 2: 24 red to 26 yellow
Choice 3: 40 yellow to 100 red
To make the same orange circle, you would need 2:3 drops of food coloring.
A ratio is defined as:A ratio is a mathematical statement that compares and equals two variables.
Fractions, percentages, and decimals are used to represent ratios.
According to this ratio (2:3), Maia uses 60% of yellow food coloring to create an orange circle for every 40% of red food coloring.
Information and calculations: 4 red food coloring drops
Yellow food coloring drops equal six.
Food coloring ratio = 4:6 or 2:3.
The ratios are as follows in percentages:
Red food coloring drops equal 40% (2/5 x 100)
60 (3/5 x 100) drops of yellow food coloring
As a result, the food coloring is divided into 40% red and 60% yellow.
