I need answers to 4 and 5!!!

Answer:

Step-by-step explanation:

The vertices of triangle ABC are A(−5, 1), B(−2.5, 7), and C(0, 1).

The given translation of vertices,

This translation shows shift x-coordinate 3 unit right and y-coordinate 1 unit down.

[tex]A(-5,1)\rightarrow A'(-5+3,1-1)[/tex]

New vertices A'(-2,0)

[tex]B(-2.5,7)\rightarrow B'(-2.5+3,7-1)[/tex]

New vertices B'(0.5,6)

[tex]C(0,1)\rightarrow C'(0+3,1-1)[/tex]

New vertices C'(3,0)

Hence, the new coordinate of the vertices are A'(-2,0) , B'(0.5,6) and C'(3,0)

Answer:

-34.72

Step-by-step explanation:

a + b + c = -44.84

a= 24.6

24.6 + b + c = -44.84

Since b = c (given "the other numbers are equal to each other")

Substitute b into c, we have

24.6 + b + b = -44.84 (b+b is the equivalence of 2 x b)

24.6 + 2b = -44.84 (subtract 24.6 from both sides)

2b = -69.44 (divide 2 from both sides)

b= -34.72

Since b = c  (given "the other numbers are equal to each other")

c is also -34.72

X+Y=100kg

X=100-Y

X*0.3+Y*0.55=100*0.5

(100-Y)*0.3+Y*0.55=50

30-0.3*Y+0.55*Y=50

0.25*Y=20

Y=80 kg

X=100-80

X=20 kg

The metal worker should use 20 kilograms of the metal alloy that is 30% copper and 80 kilograms of the metal alloy that is 55% copper.

Answer:

x=20kg

Answer:

[tex]\frac{1}{16}[/tex]

Step-by-step explanation:

Given

[tex](-1/4)^{2}[/tex]

= - [tex]\frac{1}{4}[/tex] × - [tex]\frac{1}{4}[/tex]

= [tex]\frac{1(1)}{4(4)}[/tex]

= [tex]\frac{1}{16}[/tex]

Step-by-step explanation:

So 4:5:8

= 1:n:b

which means that 4/n= 1  

n= 1x4 so n=4

Now we know that 4 is divided by 4 to get 1, so we do the same for the other two values.

5/4= 1.25 and 8/4= 2

So now place the values for n:b

n= 1.25 b=2

So n:b= 1.25:2

To check, multiply each of the values in 1:1.25:2 by 4 and see if the answer you get is the same as 4:5:8.

Answer: Multiplied by 10

Step-by-step explanation:

To find the common difference (rate or slope) we can divide the 2nd term to the 1st term.

54.2 / 5.42 = 10 (rule)

Since the common difference is the same throughout the sequence, we can name this as a "arithmetic sequence".

We can multiply 10 to 542 to find the 4th term: 542 * 10 = 5,420

It looks like you want to multiply the two functions. If so, then,

(h*g)(x) = h(x)*g(x)

(h*g)(x) = (x-5)*|x|

(h*g)(x) = x|x| - 5|x|

1 1/2 meters is equivalent to 1500 millimeters.

The correct option is (b).

To find out which option is equivalent to 1 1/2 meters, we need to convert 1 1/2 meters to millimeters.

Given:

- Gretta's height is 11/2 meters.

To convert meters to millimeters, we'll use the fact that 1 meter is equal to 1000 millimeters.

So, to convert 1 1/2 meters to millimeters:

[tex]\[ \text{1 1/2 meters} = (1 + 1/2) \times 1000 \text{ millimeters} \][/tex]

[tex]\[ = (1.5) \times 1000 \text{ millimeters} \][/tex]

[tex]\[ = 1500 \text{ millimeters} \][/tex]

So, 1 1/2 meters is equivalent to 1500 millimeters.

Therefore, the correct option is:

b. 1500 millimeters

complete question given below:

Gretta is 11/2 meters tall. Which of the following is equivalent to 1 1/2 meters?

a.150 millimeters

b.1,500 millimeters

c.100 millimeters

d.1,000 millimeters

Mrs. Wadley bought 15 white shirts and 3 black shirts.

Step-by-step explanation:

Cost of one white shirt = $4

Cost of one black shirt = $5

Students in class = 18

Money spent on shirts = $75

Let,

white shirts = x

black shirts = y

According to given statement;

x+y=18     Eqn 1

4x+5y=75   Eqn 2

Multiplying Eqn 1 by 5;

[tex]5(x+y=18)\\5x+5y=90\ \ \ \ Eqn\ 3[/tex]

Subtracting Eqn 2 from Eqn 3;

[tex](5x+5y)-(4x+5y)=90-75\\5x+5y-4x-5y=15\\x=15[/tex]

Putting x=4 in Eqn 1

[tex]15+y=18\\y=18-15\\y=3[/tex]

Mrs. Wadley bought 15 white shirts and 3 black shirts.

Answer:

x=101/65, y=-16/65. (101/65, -16/65).

Step-by-step explanation:

4x+9y=4

9x+4y=13

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

9(4x+9y)=9(4)

-4(9x+4y)=-4(13)

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

36x+81y=36

-36x-16y=-52

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

65y=-16

y=-16/65

4x+9(-16/65)=4

4x-144/65=4

4x=4+144/65

The midpoint of a line segment with endpoints at (3,-1) and (8, -4) is [tex]\left(\frac{11}{2},-\frac{5}{2}\right)[/tex]

Solution:

We have been given 2 end points of a line which are: (3,-1) and (8, -4)

The midpoint of a line segment is half way from both the ends of the line segment.

The formula for midpoint for the two points [tex]P(x_1, y_1) \text{and} Q(x_2, y_2)[/tex] is given as:

[tex]\text {Midpoint}=(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2})[/tex]

Here P(3, -1) and Q(8, -4)

[tex]\text { So } x_{1}=3 ; x_{2}=8 ; y_{1}=-1 ; y_{2}=-4[/tex]

Plugging in values in above formula, we get

[tex]\begin{array}{l}{\text {Midpoint}=(\frac{3+8}{2}, \frac{-1-4}{2}})\\\\ {\text {Midpoint}=(\frac{11}{2}, \frac{-5}{2}})\end{array}[/tex]

Hence, the midpoint of the line segment is [tex]\left(\frac{11}{2},-\frac{5}{2}\right)[/tex]

Step-by-step explanation:

Answer:

I believe it's 35 miles per gallon of gas

Answer:

35 miles per gallon

Step-by-step explanation:

Here we know that the car driven 402.5 miles on 11.5 gallons of gas, so we can write the following equivalence:

402.5 m = 11.5 g

With m being miles and g gallons.

We want to know the equivalent of miles for 1 gallon. So, lets take the equivalence and divide it by 11.5

402.5/11.5 m = 11.5/11.5 g

35 m = 1g

So, each gallon permits to travel 35 miles. If you want to verify it, just multiply 11.5 (the gallons) g by the number of miles, 35:

11.5 * 35 = 402.5

Answer:

=8.66

Answer:

(-1,5)

Step-by-step explanation:

The line x = -1 is a vertical line parallel to the y-axis.

Therefore, if the point Q(-1,5) reflects on line x = -1, then the y-coordinate of the image point will not change.

Again, as the point Q(-1,5) is on the line x = -1, therefore, the image will be the point itself i.e. (-1,5). (Answer)

The horizontal distance from point (-1,5) to the line x = -1 is zero.

Answer:

(-1,5)

Step-by-step explanation:

Answer:

C = 6 + 1.5h.

$6 is the fixed fee that the park charges.

And $1.5 is the rate of charge per hour for rent of the raft.

Step-by-step explanation:

The water park charges a rental fee plus $1.5 per hour to rent inflatable rafts.

Let the total charge (C) has a linear relationship with the number of hours (h) spent in the park and it is C = a + bh ......... (1)

Now, b is the rate of charge to rent inflatable rafts and b = $1.5 per hour.

So, C = a + 1.5h ........... (2)

Now, given that the total cost to rent a raft for 6 hours is $15.

So, from equation (2) we get,

15 = a + 1.5 × 6

⇒ a = 6

Therefore, the equation (2) becomes C = 6 + 1.5h.

Here, $6 is the fixed fee that the park charges.

And $1.5 is the rate of charge per hour for rent of the raft. (Answer)

Answer:

[tex]\frac{1}{15}[/tex]

Step-by-step explanation:

In probability,

"AND" means "multiplication"

"OR" means "ADDITION"

We want probability of Blue Pen and Yellow Highlighter. So we find individual probabilities and "MULTIPLY" them.

Let P(b) be probability of blue pen

Let P(y) be probability of yellow highlighter

We know probability of event is that event divided by total number of that

So,

There are 4 + 2 = 6 pens

Blue pen = 2

Hence,

P(b) = 2/6 = 1/3

And,

There are 5 highlighters

Yellow highlighter = 1

Hence,

P(y) = 1/5

Now,

P(b and y) = 1/3 * 1/5 = 1/15

Hence,

probability of grabbing blue pen and a yellow highlighter is  [tex]\frac{1}{15}[/tex]
