Evaluate 1 whole number 2/5 + 3/4 and give your answer to one significant figure​

Mathematics
1 answer:
ehidna [41]3 years ago
3 0

Answer:

The answer is

<h3>2 to 1 significant figure</h3>

Step-by-step explanation:

1 \frac{2}{5}  +  \frac{3}{4}

To solve the question first convert the mixed fraction to an improper fraction

That's

1 \frac{2}{5}  =  \frac{7}{5}

So we have

\frac{7}{5}  +  \frac{3}{4}

Find the LCM of the fractions

The LCM of 5 and 4 is 20

That's

\frac{7}{5}  +  \frac{3}{4}  =  \frac{7(4) + 3(5)}{20}  =  \frac{28 + 15}{20}

=  \frac{43}{20}

= 2.15

We have the final answer as

<h3>2 to 1 significant figure</h3>

Hope this helps you

A small pizza at Little Italy pizzeria costs $9.25, and each topping is an additional $0.50. So the cost of ordering a pizza can
Vera_Pavlovna [14]

Answer:

Graph the equation is shown below.

Step-by-step explanation:

The linear equation representing the relation between cost of ordering a pizza and the number of additional toppings is:

y=0.50x+9.25

Here,

<em>y </em>= cost of the pizza

<em>x</em> = number of toppings

The graph of the linear equation is shown below.

Consider the point (2, 10.25).

When <em>x</em> = 2 compute the value of <em>y</em> as follows:

y=0.50x+9.25\\=(0.50\times 2)+9.25\\=10.25

The point (2, 10.25) satisfies the equation.

Again consider a point (18, 18.25).

When <em>x</em> = 18 compute the value of <em>y</em> as follows:

y=0.50x+9.25\\=(0.50\times 18)+9.25\\=18.25

The point (18, 18.25) satisfies the equation.

The two points are also plotted on the graph.

Create 2 lines thatare parallel to 8x + 2y = 7?
Alinara [238K]

d1 = ax + by + c = 0 and d2= mx + ky + f = 0

if they are parallel :

\frac{a}{m} = \frac{b}{k} \neq \frac{c}{f}

8x + 2y = 7

8x + 2y - 7 = 0

  • 8x + 2y -9 = 0
  • 4x + y -6 = 0
  • 16x + 4y - 19 = 0

you can create more whatever you want =)

Hope this helps ^-^
