Answer:

19 Dollars

Step-by-step explanation:

Discount means that a certain percentage of the price is being deducted from the final price. So, it this case, we first have to find 5% of 20. 5% of 20 is 1 because 20 * .05 is one. Then, we just have to deduct 1 dollar from 20 dollars, making it 19 dollars.

Answer:

$6.75 + $3.50 = X

X ÷ $1,252.25

Step-by-step explanation:

$6.75 + $3.50 = $10.25

$10.25 ÷ $1,252.25 = 0.00818526652

Answer:

[tex]\%Change = -40\%[/tex]

Step-by-step explanation:

Given

[tex]Initial = 6.5kg[/tex]

[tex]Final = 3.9kg[/tex]

Required

Determine the percentage change --- Missing from the question

This is calculated as

[tex]\%Change = \frac{Final - Initial}{Initial} * 100\%[/tex]

[tex]\%Change = \frac{3.9kg - 6.5kg}{6.5kg} * 100\%[/tex]

[tex]\%Change = \frac{-2.6kg}{6.5kg} * 100\%[/tex]

[tex]\%Change = \frac{-260}{6.5}\%[/tex]

[tex]\%Change = -40\%[/tex]

Answer:

5 dollars

Step-by-step explanation:

last year he got 5 they were 7 dollars because 7x5 is 35 so do the same thing to do other it also equals 35

Answer:

Step-by-step explanation:

Let O=number of oranges and A=number of apples.

O+A=20

O=20-A

1.25A+0.95O=22.60, using O found above makes this become

1.25A+0.95(20-A)=22.60

1.25A+19-0.95A=22.60

0.3A+19=22.60

0.3A=3.6

A=12, since O=20-A

O=20-12

O=8

So she bought 8 oranges and 12 apples. The question really only asks for the number of apples bought.

12 apples were bought.

Answer:

1.25x+0.95y=22.60

x is apples y is oranges

Step-by-step explanation:

20 - 12 = 8

1.25(12) + 0.95(8) = 22.60

1.25 · 12 = $15

0.95 · 8 = $7.60

15.00 + 7.60 = $22.60

i hope that makes sense

Answer:

176

Step-by-step explanation:

First term (a) = 29

Common difference (d) = 32 - 29 = 3

For calculating the 50th term , n = 50

Now

[tex]t_{50} = a + ( n - 1) d\\t_{50} = 29 + ( 50 - 1 ) *3\\ t_{50} = 29 + 147\\t_{50} = 176[/tex]

hope it will help :)

Answer:

The equation of the line is y=-1/2x-3.5

Step-by-step explanation:

Given the two points on the line, (1, -4) and (3, -5), find the slope of the line with the equation [tex]m=\frac{y2-x2}{y1-x1}[/tex].

[tex]m=\frac{-5-(-4)}{3-1} =\frac{-5+4}{3-1} =\frac{-1}{2}[/tex]

After you find the slope of the line, substitute x and y with either point given to you. For me, I'll use point (1, -4) to solve for the y-intercept.

[tex]-4=\frac{-1}{2} (1)+b[/tex]

[tex]\frac{1}{2} -4=\frac{-1}{2} +\frac{1}{2} +b[/tex]    add both sides by 1/2 so that b is alone

[tex]\frac{-7}{2} =b[/tex]              

You can rewrite -7/2 as -3.5.

Answer:

You are supposed to correct the equation here not solve it.

Answer:

y = 3x + 3

Step-by-step explanation:

Rise: 3   Run: 1

slope (m) = 3/1 = 3

y intercept (b) = 3

y = mx + b = 3x + 3

Answer:

C (-1,-2)

Step-by-step explanation:

The fourth vertex should be on the same Y value as the 2nd vertex and the same X value as the 3rd vertex so it should be (-1,-2)

Answer:

a = 30

2a = 60

3a = 90

Step-by-step explanation:

3a + 2a + a = 180 ( Sum of angles of a triangle is 180)

6a = 180

a = 180/6

a = 30

2a = 2 x 30 =60

3a = 3 x 30 = 90

Answer:

1/5 hr or 12 min

Step-by-step explanation:

We are going to use the formula D = RT

Let t = the time for  them to be 2 mi. apart

Then 7t = the distance the ranch hand traveled

and 3t = the distance the cows traveled

Since they traveled in opposite directions, the sum of their distances will give us how far they are apart.

So, 7t + 3t = 2

10t = 2

t = 2/10 = 1/5 hr. =  12 min.

12000-7860=4140pounds.

Answer:

m∠T = 54°

Step-by-step explanation:

The measure of a straight line is 180°. (Linear angles theorem)

So, m∠WMT + 117° = 180°

m∠WMT = 180 - 117 = 63°

The base angles in an isoceles triangle are equal in measure (base angle theorem)

So,

m∠MWT = m∠WMT

m∠MWT = 63°

The sum of angles in a triangle is 180°. (Sum of angles in a triangle theorem) So,

m∠MWT + m∠WTM + m∠WMT = 180°

Substitute the measures we already found.

63 + m∠WTM + 63 = 180

Simplify.

126 + m∠WTM = 180

m∠WTM = 54°

m∠T = 54°

I hope this helps! Feel free to ask any questions!

Answer:

54°

Step-by-step explanation:

First calculate Angle WMT as: 180° - 117° = 63°

And note that Angle WMT = Angle MWT = 63°

Therefore, Angle T = 180° - 63° - 63°

Angle T = 54°
