Answers

Answer:

18 cm

Step-by-step explanation:

I hope i'm correct..

So first the formula of finding the area of a triangle is

A= 1/2 (b) (h)

If we turn the triangle we can do that.

so,

A=1/2 (6)(6)

A=1/2(36)

1/2 of 36 is 18

So, the answer is 18 cm

Answer:

18 Cm

Step-by-step explanation:

[tex]A = \frac{ab}{2}[/tex]

the tasty Deli uses 6.5 lb of ham each day how many ounces of ham will be used in 3 w
eeks ​

Answers

136.5 lbs
There’s 16 ounces in a pound
135.5 • 16
Answer is 2,184 ounces of ham will be used in 3 weeks

Answer:  2184

1lb = 16oz

6.5lb (16oz/1lb) = 104 oz

which means its 104 oz of ham uses in each day.

7 days in a week, then  3 weeks means 3 x 7 = 21 days

104oz in a day, 21 days (3 weeks) equals 21 x 104 = 2184 oz

Which figure has rotational symmetry but no line symmetry?
A) Figure 1
B) Figure 2
C) Figure 3
D) Figure 4​

Answers

Answer:

In my opinion i would think A but it might be P also, sorry im not sure but thats my best guess.

Step-by-step explanation:

Figure 4 has rotational symmetry but no line symmetry.

Option D is correct.

Symmetry :

The rotational symmetry of a shape explains that when an object is rotated on its own axis, the shape of the object looks the same.

Some of the examples are square, circle, hexagon.A line of symmetry is a line that cuts a shape exactly in half. It means that if we fold the shape along the line, both halves would match exactly.

From given figure, It is observed that figure 4 has rotational symmetry but no line symmetry.

The probability of rolling a number cube and getting a 6 and 3.

Answers

We have to find out the probability of getting 6 and 3,

Since this only one roll it is not possible to get 2 numbers in one roll

So, I will presume you want the probability of getting 6 or 3,

Total number of outcomes= {1,2,3,4,5,6} = 6 outcomes

Number of favorable outcomes = {3,6} = 2 outcomes

Probability of rolling 6 or 3 = [tex]\frac{Number'of 'favorable' outcomes}{Total' number 'of' outcomes}[/tex]

= 2/6

= 1/3 or 0.33333%

Therefore the probability of rolling 6 or 3 is one in three chances
