the area is 233.6m^2

Answer:

233.6m²

Step-by-step explanation:

Area of a triangle formula:

[tex]A = \frac{(h)(b)}{2}[/tex]

Plug in the numbers:

A = 7.3*64/2

What is the width of this rectangular prism if the volume is 162 cm cubed?
A. 3 cm.
B. 3 cm. squared
C. 3 cm. cubed
D. 108 cm.

Answers

Answer:

A 3 cm

Step-by-step explanation:

Volume is lxwxh, 6x9= 54, and 54x3=162

Answer: 3

Step-by-step explanation:

The equation for volume of a rectangular prism is lwh. We have the lh and 6 times 9 is 54. Now we just divide 162 and 54 and that's the width which is 3. And to double check 3 times 9 times 6 is 162 :)

John has a box of nails. The box contains 65 small nails, 40 medium nails, and 45 large nails. Susan has a box of nails that has the same proportion of small, medium, and large nails as John's box. There are 176 medium nails in Susan's box.

What is the total number of nails in Susan's box?

Answers

Answer:

326

Step-by-step explanation:

Add a nails: 65+40+45+176= The answer

660

Step-by-step explanation:

John

65s (small)

40m (medium)

45 L (large)

Susan

x small

176m

y large

From question:

Susan has a box of nails that has the same proportion of small, medium, and large nails as John's box =Meaning same ratio

John ratio. Susan

s : m : L s : m : L

65 : 40 : 45. 13 : 8 : 9

13 : 8 : 9. x : 176 : y

x = (176/8)*13

=286

y = (176/8) * 9

= 198

Total number of nails in Susan box

= x + 176 + y

= 286 + 176 + 198

=660

Answers

Answer:

x = 5

Step-by-step explanation:

4x + 2y + z = 24

2x - 3y - z = 2

5x + y + 2z = 21

-----------------

Eliminate z

Add the 1st and 2nd eqn

4x + 2y + z = 24

2x - 3y - z = 2

----------------

6x - 1y = 26 eqn A

Multiply the 2nd eqn by 2, then add the 3rd.

4x - 6y -2z = 4

5x + y + 2z = 21

----------------

9x - 5y = 25 eqn B

---------------

Now you have 2 eqns in 2 unknowns, not 3.

Multiply eqn A by 5 and subtract eqn B.

30x - 5y = 130 eqn A times 5

9x - 5y = 25 eqn B

-------------

21x = 105

x = 5

Answer:

x = 5 is the answer

For lines c, d and e, m1 = 90° and m3=90°



For the given diagram and angle measures, use complete sentences to describe each pair of lines as parallel or perpendicular. In your description, include the special angle relationship between angles 1 and 3.
lines d and e
lines d and c

Answers

The relationship between angles 1 and 3 is that they are congruent, or equal to each other. they have the same measure.

Lines D and E seem to be a pair of lines that are parallel to each other, which is what makes angles 1 and 3 congruent

Lines D and C seem to be perpendicular to each other, which would make angles 1 and 3 right angles.

Three ropes of length 2 m 84 cm, 4 m 26 cm and 7 m 10 cm are to be cut into small pieces of equal length. What is the greatest possible length of each equal part, so that there is no wastage? How many pieces are there in total?

Answers

1 m 42 cm, there would be 10 pieces in total. i believe this is right.

The greatest possible length of each piece is 2 cm.

What is HCF?

The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.

Three ropes of length 2 m 84 cm, 4 m 26 cm, and 7 m 10 cm are to be cut into small pieces of equal length.

We have been given the lengths of the ropes as

2 m 84 cm = 284cm

4 m 26 cm = 426cm

7 m 10 cm= 710 cm

We have to determine the greatest possible length of each equal part So that there is no wastage

So the greatest possible length of each piece will be the HCF of the length of the ropes.

⇒ 284 = 2× 142

⇒ 426 = 2 × 213

⇒ 710 = 2 × 355

Hence, the HCF of the 284, 426, and 710 is 2.

Therefore, the greatest possible length of each piece is 2 cm.

Answer: 7/10, 7/10 and 3/10.

Step-by-step explanation:

7/10 = Between 1 and 10, the multiples of three are 3, 6, and 9. So the amount favourable outcomes is the total minus the multiples, 10-3 = 7. So 7/10.

7/10 = Between 1 and 10, the multiples of 2 are 2, 4, 6, 8, and 10. The multiples of 3 are 3, 6 and 9. That, gives 7 favourable outcomes (6 is a multiple of both but counted once) giving the probability of 7/10.

3/10 = The favourable outcome is 8 and above, so: 8, 9 and 10. There are 3 favourable outcomes which gives the probability of 3/10.

You have the 1st one correct...
The second one is 8/10...
The 3rd is 3/10

Circumstance of a curcle C=2*pi*r

So if you want to find r from this equation you come up with r=C/2*pi. That's exactly what they give you in the problem.

Now you know that C= 26.69 so replacing what we know in the formula r=C/2*pi you get

r=26.69/2*3.14 =4.25

So looking at the figure you they said r=4.25

That means that the figure is has to be a circle.
