A) (-2, 14/3)
B) (2, -7/3)
C) (-2, 7/3)
D) (3, 14)

Answers

Answer 1

Answer:

The co-ordinates of A' is

A)  [tex](-2,\frac{14}{3})[/tex]

Step-by-step explanation:

Given point:

(-3,7)

The point is dilated with a scale factor  [tex]r=\frac{2}{3}[/tex]  with the center of dilation at the origin.

To find the co-ordinates of the dilated point A'.

Solution:

Any  point dilated with the center of dilation at the origin with a scalar factor [tex]k[/tex] is given by:

[tex]D(x,y)\rightarrow D(kx,ky)[/tex]

Thus, the point (3,-7) dilated with a scale factor  [tex]r=\frac{2}{3}[/tex]  with the center of dilation at the origin  is given as :

[tex]A(-3,7)\rightarrow A'(\frac{2}{3}\cdot -3,\frac{2}{3}\cdot 7)[/tex]

[tex]A(-3,7)\rightarrow A'(-2,\frac{14}{3})[/tex]

Thus, the co-ordinates of A' is [tex](-2,\frac{14}{3})[/tex].

Heather is making a blanket for her baby and is going to put a ribbon border around it. The blanket will be 3 feet by 5 feet. The fabric for the blanket cost $1.25 per square yard and the ribbon costs $.50 per foot. What is the approximate total cost for the blanket? A) $1.75 B) $10.08 C) $20.84 D) $26.75 E) $32.48

Answers

Answer:

The approximate total cost for the blanket is $10.08 ⇒ B

Step-by-step explanation:

The formula of the area of a rectangle is A = L × W

The formula of the perimeter of a rectangle is P = 2(L + W)

where:

L is the length of the rectangleW is the width of the rectangle

∵ The baby blanket shaped a rectangle

∵ The dimensions of the blanket are 3 feet and 5 feet

- Find the area of the blanket

A = 3 × 5 = 15 feet²

- Change feet to yard because the cost is by square yard

∵ 1 foot = [tex]\frac{1}{3}[/tex] yard

∴ 1 foot² = [tex](\frac{1}{3})^{2}=\frac{1}{9}[/tex] yard²

∴ 15 feet² = 15 × [tex](\frac{1}{9})[/tex] = [tex]\frac{5}{3}[/tex] yards²

The area of the blanket is  [tex]\frac{5}{3}[/tex] yards²

∵ The fabric cost of the blanket is $1.25 per square yard

∴ The fabric cost =  [tex]\frac{5}{3}[/tex] × 1.25

The fabric cost = 2.08333 dollars

∵ Heather is going to put a ribbon border around it

- The length of the ribbon is equal to the perimeter of the blanket

∵ P = 2(3 + 5) = 16 feet

The length of the ribbon is 16 feet

∵ The cost of the ribbon is $0.5 per foot

∴ The cost of the ribbon = 16 × 0.5

The cost of the ribbon = 8 dollars

Now add the fabric cost to the ribbon cost to find the total cost of the blanket

∵ The total cost = 2.08333 + 8

∴ The total cost = 10.08333

- Round it to the nearest cent

∴ The total cost = 10.08 dollars

The approximate total cost for the blanket is $10.08

The rate in miles per gallon will be 45 miles per gallon. Then the correct option is D.

What is conversion?

Conversion means to convert the same thing into different units.

In a test, a hybrid car drove 619 yards on 1 fluid ounce of gasoline.

We know that 1 yard = 1/1760 miles. Then we have

619 yards = 619 x 1 / 1760 miles

We know that 1 fluid ounce = 1 / 128 gallons

The rate in miles per gallon will be

R = (619 / 1760) / (1 / 128)

R = 619 x 128 / 1760

R = 45 miles per gallon

The rate in miles per gallon will be 45 miles per gallon. Then the correct option is D.

A rectangle flag had a width of 3 2\3 feet and area of 8 3/4 square feet . Which expression could be used to calculate the length , in feet , of the rectangle

Answers

Pretty sure it's 8 3/4  ÷ 3 2/3.

Why?

So say you want to find the length of a rectangle who's area is 6, and the width is 2. You can divide the area by the width to find the length. 6/2 = 3.

Check: 2 * 3 = 6.

Back to the original question: 8 3/4 ÷ 3 2/3.

Improper fractions: 35/4 ÷ 11/3.

Switch division to multiplication and reciprocal: 35/4 * 3/11.

35/4 * 3/11 = 105/44.

Check:

105/44 * 11/3 = 1155/132 = 35/4 = 8 3/4

Length = 105/44

Final answer:

To find the length of the rectangle, we use the formula Area = length  imes width, converting the given mixed numbers into improper fractions, and then dividing the area by the width.

Explanation:

To calculate the length of the rectangle given the width and the area, we can use the formula for the area of a rectangle: Area = length  times width. To isolate the length, we divide both sides of the equation by the width. Given that the width of the rectangle is 3 2/3 feet and the area is 8 3/4 square feet, the expression to find the length is:

Length = Area / Width

First, we convert the mixed numbers into improper fractions:

Width: 3 2/3 = 11/3 feet

Area: 8 3/4 = 35/4 square feet

Then, the calculation for the length is:

Length = (35/4) / (11/3) feet

Vince has a rectangular rug in his room with an area of 10 ft the length of the rug is 18 inches longer than the width what could be the dimensions of the rug?

Answers

The length of the rug is 4 ft.

The width of the rug is 2.5 ft.

Explanation:

The area of the rug is 10 ft.

The length of the rug be l.

Let us convert the inches to feet.

Thus, [tex]18 inches = 1.5 ft[/tex]

Thus, the length of the rug is [tex]l=1.5+w[/tex]

Let the width of the rug be w.

Substituting these values in the formula of area of the rectangle, we get,

[tex]A=length\times width[/tex]

[tex]10=(1.5+w)(w)\\10=1.5w+w^2\\w^2+1.5w-10=0[/tex]

Solving the expression using the quadratic formula,

[tex]$w=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$[/tex]

Substituting the values, we have,

[tex]$w=\frac{-15 \pm \sqrt{15^{2}-4 \cdot 10(-100)}}{2 \cdot 10}\\[/tex]

[tex]$w=\frac{-15 \pm \sqrt{4225}}{20}$[/tex]

[tex]$w=\frac{-15 \pm 65}{2 0}$[/tex]

Thus,

[tex]w=\frac{-15 + 65}{2 0}\\w=\frac{50}{20} \\w=2.5[/tex]  and   [tex]w=\frac{-15 - 65}{2 0}\\w=\frac{-80}{20} \\w=-4[/tex]

Since, the value of w cannot be negative, the value of w is 2.5ft

Thus, the width of the rug is 2.5ft

Substituting [tex]w=2.5[/tex] in [tex]l=1.5+w[/tex], we get,

[tex]l=1.5+2.5\\l=4[/tex]

Thus, the length of the rug is 4 ft.

Amelia’s hourly wage is $3.50 less than double David’s hourly wage. Write an equation to find David’s hourly wage

Answers

The equation to find David’s hourly wage is:

David’s hourly wage =  [tex]\frac{1}{2}[/tex] x + 1.75, where x represents Amelia’s hourly wage

Step-by-step explanation:

The given is:

Amelia’s hourly wage is $3.50 less than double David’s hourly wage

We need to find an equation to find David’s hourly wage

Assume that:

Amelia's hourly wage is xDavid’s hourly wage is y

∵ Amelia’s hourly wage is $3.50 less than double David’s

   hourly wage

- That means multiply David’s hourly wage by 2, then

    subtract 3.50 from the product to get Amelia’s hourly wage

∴ x = 2y - 3.50

Now let us find y in terms of x

∵ x = 2y - 3.50

- Add 3.5 to both sides

∴ x + 3.50 = 2y

- Divide each term by 2

∴ [tex]\frac{1}{2}[/tex] x + 1.75 = y

- Switch the two sides

∴ y =  [tex]\frac{1}{2}[/tex] x + 1.75

∵ y represents David’s hourly wage

∴ David’s hourly wage =  [tex]\frac{1}{2}[/tex] x + 1.75, where x represents

   Amelia’s hourly wage

The equation to find David’s hourly wage is:

David’s hourly wage =  [tex]\frac{1}{2}[/tex] x + 1.75, where x represents Amelia’s hourly wage

What is one whole and three fourths plus five sixths plus one whole and one fourth

Answers

Answer:

First of all  cant give u the anssswer i am srry but i can give u a hint u need to find eqivelent fractions for the denominators then u can add them

Step-by-step explanation:

Answer: The answer is Three whole and five sixths (3 5/6)

Step-by-step explanation: One whole and three fourths can be expressed as 1 3/4, and this is added to five sixths, that is, 5/6. therefore these can be expressed as

[1 3/4 + 5/6}

The other part of the questions says one whole and one fourth which can be expressed as 1 1/4.

The entire question can now be written out as

[1 3/4 + 5/6] + [1 1/4]

We would start by solving for the left hand side of the expression

1 3/4 + 5/6

= 7/4 +5/6

By using a common denominator which is 12 (the LCM), the expression now becomes,

[21 + 10]/12

= 31/12

We can now add this to the right hand side of the expression. Thus,

[31/12] + 1 1/4

=31/12 + 5/4

By using a common denominator which is also 12, the expression now becomes,

[31 + 15]/12

= 46/12, By simplifying further we arrive at,

23/6.

Written as a proper fraction, this becomes

3 5/6 (Three whole and five sixths)

Sarah opens a savings account that has a 2.75% annual interest rate, compounded monthly. She deposits $500 into the

$500.00
$754.94
$1255.27
$255.27

Answers

Therefore $754.94 will be in account after 15 years.

Step-by-step explanation:

Given , Sarah opens a saving account that has a 2.75% annual interest rate , compounded monthly. She deposits $500 into the account.

P = $500, r = 2.75% = 0.0275 , t = 15 years and n= 12

[tex]Amount (A) =P(1+\frac{r}{n})^{nt}[/tex]

                 [tex]=\$500(1+\frac{0.0275}{12})^{(12\times15)}[/tex]

                  =$754.94

Therefore $754.94 will be in account after 15 years.

Final answer:

After 15 years with a 2.75% annual interest rate, compounded monthly, an initial deposit of $500 in a savings account will grow to approximately $754.94.

Explanation:

The student has asked how much money will be in a savings account after 15 years with an initial deposit of $500 if the account has a 2.75% annual interest rate, compounded monthly. To calculate the future value of this account, we can use the compound interest formula:

A = P (1 + r/n)^(nt)

Where:

Here, P is $500, r is 0.0275 (2.75% expressed as a decimal), n is 12 (since the interest is compounded monthly), and t is 15 years.

So, the calculation is:

A = $500 * (1 + 0.0275/12)^(12*15)

By computing this, we can determine the future value of the savings account after 15 years:

A ≈ $500 * (1 + 0.00229167)^(180)

A ≈ $500 * (1.00229167)^180

A ≈ $500 * 1.510383954

A ≈ $754.94

Therefore, the amount in the savings account after 15 years will be approximately $754.94.

Answers

The average speed calculated over the given time intervals is

48.42 m/s, 49.35 m/s, 50.09 m/s, 50.26 m/s, and 50.29 m/s. The estimated speed when t = 1 is 50.28 m/s.

Given formula is y = 54t - 1.86t²

Speed = dy/dt = 54 - 3.72t

a) Average speed over the time intervals given below are:

In [1, 2] time interval, it is [tex]\frac{54t - 1.86t^{2} }{2-1} = \frac{54t - 1.86t^{2} }{1}[/tex] = 48.42 m/sIn [1, 1.5] time interval, it is[tex]\frac{54t - 1.86t^{2} }{1.5-1} = \frac{54t - 1.86t^{2} }{0.5}[/tex] = 49.35 m/sIn [1, 1.1] time interval, it is [tex]\frac{54t - 1.86t^{2} }{1.1-1} = \frac{54t - 1.86t^{2} }{0.1}[/tex] = 50.09 m/sIn [1, 1.01] time interval, it is [tex]\frac{54t - 1.86t^{2} }{1.01-1} = \frac{54t - 1.86t^{2} }{0.01}[/tex] = 50.26 m/sIn [1, 1.001] time interval, it is [tex]\frac{54t - 1.86t^{2} }{1.001-1} = \frac{54t - 1.86t^{2} }{0.001}[/tex]= 50.29 m/s

b) When t = 1, the speed is v = 50 - (3.72*1) = 50.28 m/s

Answer:

1)m<DCH =89

2)m<BCD=103

Step-by-step explanation:

1) We have that:

m<EFB=91 degree.

We want to find m<DCH.

By same side interior angle property:

m<DCH +m<EFB=180

m<DCH +91=180

m<DCH=180-91

m<DCH =89

2) Given that: m<HFG=103, we seek to find m<BCD.

By the alternate exterior angle property:

m<HFG=m<BCD

Therefore

m<BCD=103

Dave, Frank, and Kathy can process 1,300 catalog orders per day when all three of them are working. Dave and Frank can do 780 orders per day and Frank and Kathy can do 850 orders per day. How many can each do in a day?

Answers

(1) x+y+z=1300
(2) x+y=780 => x = 780 - y
(3) y+z=850 => z = 850 - y

Replace x and z with y in function (1)

780 - y + y + 850 - y = 1300
1630 - y = 1300
y = 330

Therefore, x = 780 - y = 780 - 330 = 450
z = 850 - y = 850 - 330 = 520

Dave can do 450 catalog orders per day
Frank can do 330 catalog orders per day
Kathy can do 520 catalog orders per day
