Can a triangle be formed with the sides lengths of 7 cm, 5 cm and 12 cm?

Mathematics

laiz [17]3 years ago

Answer:

NO because 7+5=12

The sum must be larger (not equal to) the longest side. If it's exactly the same, there's no room to for the shorter two sides to angle up to form a triangle.

If Keira spends $45 on petrol, 1/ 9 of the money on other items and 1 /5 of the money on clothes. How much money does she spend
gogolik [260]

Answer:

The money Keira spent on food is $31.

Step-by-step explanation:

Total money spent by Keira = $45

Things Keira spent money on:

1. Clothing

2. Food

3. Other items

Money spent on Clothing = 1/5 of total money

= 1/5 x $45

Money spent on Clothing = $9

Money spent on Other Items = 1/9 of total money

= 1/9 x $45

Money spent on Other Items = $5

Money spent of on Food = Money spent - (Money spent on clothing + other items)

Money spent on food = 45 - (9+5)

= 45 - 14

Money spent on food = $31

What is the vertex of the absolute value function defined by ƒ(x) = |x - 2| - 7?
inn [45]
<h3><u>Explanation</u></h3>
  • Modulus Function

y = a |x  - h|  + k

The structure or equation is similar to a quadratic function.

The value of a determines the slope of graph.

Tthe value of h determines the horizontal shift of graph.

The value of k determines the vertical shift of the graph.

From the given equation,

f(x) =  |x - 2|  - 7

We can say that the graph shifts to the right 2 units and shifts down 7 units. Hence the vertex would be at x = 2 and y = -7. It can be written in coordinate form as (2,-7).

<h3><u>Answer</u></h3>

<u>\large{(2,-7)}</u>

Find the value of x and the measure of each angle in the parallelogram
Morgarella [4.7K]

Answer:

\angle D= 162\\\\\angle E = 18\\\\\angle F = 162\\\\\angle G = 18

Step-by-step explanation:

By properties of parallelograms we know that opposite are the same so we have

12x=4(x+3)\\\\4(3x)=4(x+3)\\\\3x=x+3\\\\2x=3\\\\x=\frac{3}{2}

so for the angles we have

\angle G=\angle E=12(\frac{3}{2})=18\\\\\angle D=\angle F = 180-\angle G=180-18=162
