Answer 1

Answer:

(5,-1) and choice A

Step-by-step explanation:

The first step is to figure out where the two vectors are. Since one goes to (2,-3) and the other goes to (3,2), you already know that the only possible correct answer choices could be A and B, since C and D go to the wrong coordinates. Since the two vectors are originating from the same point and are not build on top of each other, you solve this by averaging them instead of adding head to tail. Using the pythagorean theorem, you know that the length of the new vector will be [tex]\sqrt{(3^2+2^2)+(3^2+2^2)}=\sqrt{26}[/tex]. The side lengths have length 5 and 1, since [tex]5^2+1^2=26[/tex]. Therefore, the coordinates of the new vector are (5,-1). Hope this helps!

If she used 3 ¾ cups of bread flour to make 1 pizza, what is ⅛ of the amount of bread flour she used?

Answers

Answer:

[tex]\frac{15}{32}[/tex] cups of bread flour.

Step-by-step explanation:

Multiply 3 [tex]\frac{3}{4}[/tex] by [tex]\frac{1}{8}[/tex]

[tex]\frac{1}{8} * 3 \frac{3}{4} = \frac{1}{8} *\frac{15}{4} =\frac{15}{32}[/tex]

What is the scale factor, perimeter ratio, surface ratio, and the volume ratio?????????????????????????????

Answers

Answer:

Scale factor = [tex]\frac{4}{9}[/tex]

Perimeter ratio = 4 : 9

Surface area ratio = 16 : 81

Volume ratio = 64 : 729

Step-by-step explanation:

Volume ratio = [tex]\frac{\text{volume of small prism}}{\text{Volume of large prism}}[/tex]

                      = [tex]\frac{128}{1458}[/tex]

                      = [tex]\frac{64}{729}[/tex]

                      = 64 : 729

Scale factor = [tex]\sqrt[3]{\frac{\text{volume of small prism}}{\text{Volume of large prism}}}[/tex]

                    = [tex]\sqrt[3]{\frac{64}{729}}[/tex]

                    = [tex]\frac{4}{9}[/tex]

Perimeter ratio = Scale factor

                         = [tex]\frac{4}{9}[/tex]

                         = 4 : 9

Surface area ratio = (Scale factor)²

                              = [tex](\frac{4}{9})^{2}[/tex]

                              = [tex]\frac{16}{81}[/tex]

                              = 16 : 81

Answer:Scale factor = 4/9

Perimeter ratio = 4 : 9

Surface area ratio = 16 : 81

Volume ratio = 64 : 729

Answers

Part (a)

Answer: 42

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

Work Shown:

The angle ABC is 90 degrees since AB and BC are perpendicular. The two segments form a right angle. Therefore, the three pieces of the angle must add to 90

24+x+24 = 90

x+48 = 90

x+48-48 = 90-48 ... subtracting 48 from both sides

x = 42

=======================================

Part (b), subpart (i)

Angle q is congruent to the 135 degree angle because they are vertical angles.

Vertical angles are opposite angles formed by the X shape when two lines cross, and vertical angles are always the same measure.

=======================================

Part (b), subpart (ii)

Answer: 225

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

Reasoning:

The four angles p,q,r and the 135 all add to 360, so,

p+q+r+135 = 360

subtract 135 from both sides so we isolate the "p+q+r" and that leads to

p+q+r+135 = 360

p+q+r+135-135 = 360-135

p+q+r = 225

Answers

Answer:

Step-by-step explanation:

Susan started her homework at = 1:59 pm

She took time = 96 mins

Time at which she had volleyball practice = 4:00 pm

So, time between her starting of homework and starting of volleyball is given by

1:59 pm to 4:00 pm = 2 hrs and 1 mins

2 hr 1 min = 120 mins + 1 min = 121 mins

But she took 96 mins to do her homework, so

Out of 121 mins, 96 mins she took for homework

Remaining time = 121 mins - 96 mins = 25 mins

Therefore, time Susan had between finishing her homework and the beginning of volleyball practice is 25 mins

6x+5 = 7x -6

Subtract 6x from each side

6x-6x+5 = 7x-6x -6

5 = x-6

Add 6 to each side

11=x

We want to find AB

AB = 6x+5+7x-6

AB = 13x -1

     = 13(11) -1

     =143-1

     = 142

A race has 6 competitors. The winner gets a gold ribbon, the second-place finisher gets a blue ribbon, and the third-place finisher gets a red ribbon. In how many ways can the ribbons be awarded?

Answers

Answer:

120 ways

Step-by-step explanation:

Here, we want to calculate the number of ways in which the ribbons can be awarded.

There are 6 competitors and there should only be one first position. What this means is that there are 6 possible ways to become first and 6 possible ways to clinch the gold ribbon.

Now, looking at the second position, since one person already claimed the first, there would be only 5 of the competitors jostling for the second position. This means that the number of ways they can claim the blue ribbon is 5 ways

For the fourth position, there are only 4 competitors wanting to claim the red ribbon. This is because we already have winners for the first and second position.

The number of ways this can be done is thus 4 ways

Now the total number of ways the ribbons can be awarded would be 6 * 5 * 4 = 120 ways

the center of a circe is located at (1,3). The point (0,1) lies on the circle. Find the equation of the circle

Answers

Answer:

[tex](x-1)^{2}+(y-3)^{2} = 5[/tex]

Step-by-step explanation:

Given the general equation of a circle represented as:

[tex](x-a)^{2}+(y-b)^{2} = r^{2}[/tex] where:

(a, b) is the centre of the circle and r is the radius

Given the centre located a (1,3), to get the radius we will take the distance between the centre point of the circle the the point that lies on its circumference i.e (0,1).

Using the formula for calculating thee distance between 2 points, we have:

[tex]r = \sqrt{ (x2-x1)^{2}+(y2-y1)^{2}}[/tex]

x1 = 1, y1 = 3, x2 = 0, y2 = 1

[tex]r = \sqrt{ (0-1)^{2}+(1-3)^{2}}\\r=\sqrt{1^{2} +(-2)^{2}}\\r=\sqrt{1+4}\\r=\sqrt{5}[/tex]

Substituting this values of the centre and radius of the circle into the general equation of a circle we have:

[tex](x-1)^{2}+(y-3)^{2} = (\sqrt{5}) ^{2}\\(x-1)^{2}+(y-3)^{2} = 5[/tex]

This gives the required equation of the circle.

A box tube is to be constructed out of 1 cm thick metal that has a width of 10cm, a height of 6cm, and a depth of 15 cm. Which of the following represents the volume of the metal used?
(1) 420 cm3 (3) 640 cm3
(2) 540 cm3 (4) 760 cm3

Answers

Answer:

(A)[tex]420$ cm^3[/tex]

Step-by-step explanation:

Width = 10cmHeight = 6cmDepth = 15 cm

Volume of the solid box [tex]= 10*6*15=900$ cm^3[/tex]

Since the box tube is constructed out of 1 cm thick metal, we subtract 1cm on both sides of the width and height.

See the attached diagram for illustration.

Internal width of the box = 10-2=8cmInternal height of the box = 6-2=4cm

However, the depth of the box remains unchanged, therefore:

Internal depth of the box =15cm

Internal Volume of the box[tex]=8*4*15=480$ cm^3[/tex]

Volume of metal used = Volume of Solid Box - Internal Volume

=900-480

=[tex]420$ cm^3[/tex]

The correct option is A.
