Hi , hello 9+5-4+2=?

Answer:

Thus the answer is 127

Step-by-step explanation:

4 feet = 48 inches. 2.54 = 1 inch.

It is found that Joan's  height is 127 centimetres.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that Joan is 4 feet 2 inches tall and we need to change to centimeters .

First we change her height to inches;

1 Foot = 12 Inches

Therefore, 4 Feet = 4 x 12 = 48 inches

The Total height in inches =48 inches + 2 Inches = 50 inches

Now, we have gotten her height in inches, change  to centimetres.

We have that;

1  inch =2.54 centimeters

50inches = 50 x 2.54 cm

=127 centmeters.

Hence, Joan's height is 127 centimetres.

The estimate of the square roots and cube roots of numbers can be found by an iterative process;

The Pythagoras's Theorem, PT, and its Converse: Estimating Square Roots

1. The perfect squares that are close to the number for which the square root is sought are listed

Example, to find the square root of 5, we have;

2², 5, 6, 7, 8, 3²

Therefore, the perfect square close to 5 are those of 2 and 3

The number 5 is then divided by the root of the number with closest perfect square, which is √4 = 2

Therefore, we have;

The average of the result of the division and the divisor is then found as follows;

The required number is then divided again by the average, 2.25, again, to get;

The average of the new quotient and the divisor is found again as follows;

Repeat dividing the required number by the average again as follows;

The average is found again as 2.23606797792

Dividing 5 gives 2.23606797708

Therefore;

2. To estimate a cube root of a number, the closest, numbers with a perfect cube are listed

To estimate the cube root of 9, the closest perfect cubes are 8 and 27

We have;

∛8 < ∛9 < ∛27

2 < ∛9 < 3

Given that we have;

The difference between 9 and 8 = 1

The difference between 9 and 27 = 18

Therefore, the cube root of 9, ∛9 ≈ 2

For more accurate value, we have

[tex]{} \hspace {8pt}2.08\\3| \overline {9.000 000}\\ {} \hspace {-3pt} -8\\ {} \hspace {8pt} 1 \ 000 \ 0[/tex]

Where, the 2 in the quotient is given from the closest perfect cube to 9;

2³ = 8 < 9

The 8 is given from 2³ = 8

The 1 is given from 9 - 8 = 1

The 000, is obtained by bringing down 000, from the dividend

Next; Multiply 300 by 2² to get 1,200

1,200 is larger than 1,000, which is the remainder, therefore, a decimal point and 0 is added to the quotient, and a zero is added to the remainder to give 10,000, from which we have;

[tex]\dfrac{10,000}{300 \times 2^2} = 8\frac{1}{3}[/tex]

The quotient, 8 is added to the quotient line after the zero, to get;

∛9 ≈ 2.08

Answer:

x=8

Step-by-step explanation:

normally it would be 2x-1=[tex]\frac{3}{4}[/tex]x+9 so now we have to combine the x into one fraction which will be 2x-1=[tex]\frac{3x}{4}[/tex]+9 now for my way i will be taking the -1 to the other side and when that happens its going to become positive so now the answer will be 2x=[tex]\frac{3x}{4}[/tex]+10 ok so now we have to have the x's to the same side so i have to drag the fraction to the other side and making it positive which will conclude into 1.25x=10 and now 10 divided by 1.25 is 8 so the answer is x=8 (sorry for the ok nows) hope this helped

Answer:

These ratios are not equivalent.

Step-by-step explanation:

If you get 5 pairs of socks for $15, that means that each pair of socks are $3. If you buy 10 pairs of socks for $25, you are spending $12.50 for each pair. If you double the 5 pairs of socks for 10 pairs of socks, you will be spending $30 because you have to add another $15.

So between 10 pairs of socks for $30 (5 pairs of socks for $15) and 10 pairs of socks for $25, you will be spending more on the 5 pairs of socks.

You are spending more money on the 5 pairs of socks for $15.

Answer:

(a) f(7) = 23

(b) x = 13/3

Step-by-step explanation:

Step 1: Define

f(x) = 3x + 2

(a) f(7) is x = 7

(b) f(x) = 15

Step 2: Substitute and Evaluate

(a) f(7) = 3(7) + 2

f(7) = 21 + 2

f(7) = 23

(b) 15 = 3x + 2

13 = 3x

Answer:

$3.50 for 1 quart

Step-by-step explanation:

Point (n, a) on the graph represents the number of quarts and the Amount paid(in $).

Graphs are a popular tool for visually illuminating data relationships. A graph serves the objective of presenting data that are either too many or complex to be fully expressed in the text while taking up less room.

Given, The graph shows the number of quarts picked and the amount of money the customer paid. Another customer pays $8.75 for the strawberries she picks.

Slope of the given graph  = y₂ - y₁ / x₂ - x₁

Slope of the given graph  = 3.5-0 /1-0 = 3.5

As the Graph is passing through the origin point

Hence, the equation of the line will be y = mx

Where slope(m) = 3.5

thus the equation of the given graph  y = 3.5 x

For another customer given, y = 8.75

Hence x = 8.75/3.5

x = 2.5

Coordinates over the graph will be(2.5, 8.75)

Therefore, The number of quarts and the amount paid (in dollars) are represented by the graph's points (n, a).

Answer:

96 gallons

Step-by-step explanation:

So to wash 4 loads of dishes, you need 32 gallons.  If you divide 32 by 4 you get 8.  That means you need 8 gallons of water per load.  Since there are 12 loads and you need 8 gallons per load, if you multiply 8 X 12 you get 96.  This means you need 96 gallons of water for 12 loads of dishes.  Hope it helps!
