Answer 1

Answer:

5 five dollar and 7 one dollar

Step-by-step explanation:

let the number of one dollar be xthe number of five dollar be y

1x+5y=32

x+y=12

using elimination method

+x-x-y+5y-32+12=0

4y-20=0

4y=20

divide both side by 4

y=20/4 =5

so, if. y is 5 then x is

5y+x=32

5(5)+x=32

25+x=32

x=32-25

x=7

Answer:

clockwise90°origin

Step-by-step explanation:

The answer statement tells you the transformation is a rotation. The original is in the 2nd quadrant, and the image is in the 1st quadrant, representing a clockwise rotation. AB points east, while A'B' points south, a rotation of 90° (clockwise). Each image point is the same distance from the origin as its preimage point. The origin is the center of rotation.

solve the equation 1/4 x + 2 = 6

Answers

Answer:

x = 16

Step-by-step explanation:

Step 1: Subtract 2 from both sides.

[tex]\frac{1}{4}x + 2 = 6[/tex] [tex]\frac{1}{4}x+2-2=6-2[/tex] [tex]\frac{1}{4}x=4[/tex]

Step 2: Multiply each side by 4 in order to isolate x.

[tex]\frac{1}{4}x * 4 = 4 * 4[/tex] [tex]x = 16[/tex]

Therefore, x = 6.

Hope you have a lovely rest of your day/night.

Answer:

during the work week mrs. Jamison drive 75 miles each way to work if she works 21 days each month how far does she drive for the work during the month​

Answers

Answer:

See below:

Step-by-step explanation:

So, the question asks how far she drives in a month, this probably includes going to work and coming back. Therefore, each day takes 2 times 75 which is 150!

Now, we know she goes 150 miles each day going to work and coming back. We can now multiply that by 21 to get out answer.

We can split 21 into 10 * 2 + 1 for our convenience.

150 times 10 is 1500 and that times two is 3000 added by 150 is 3150.

Then we get out answer; 3150 miles!

The monthly cost of of the subscription without applied coupon is 12 dollars.

What is unitary method ?

Unitary method is a mathematical technique for first finding the value of a single unit then deriving the given unit by multiplying with it.

According to the given question Butter Crate Snacks sends a selection of treats in the mail each month and Sidney bought a 4-month subscription for a friend.

She used a coupon of 8 dollars and the price she paid with coupon applies is 40 dollars.

∴ Price without the coupon is (40 + 8) dollars.

= 48 dollars.

So, 4 months of subscription costs 48 dollars.

∴ 1 month of of subscription will cost 48/4 dollars.

= 12 dollars.

Answers

Answer:

250 $3 tickets and 100 $2 tickets were sold.

Step-by-step explanation:

A family bought a total of 13 tickets to a magic show, some adult and some child. The family paid a total of $85 Adult tickets are $15 each and tickets are $5 each. Let X represent adult tickets. Let y represent child tickets Write an equation to model the total amount of money that they spent.The cost of tickets for a play is $3.00 for adults and $2.00 for children. 350 tickets were sold and $950 was collected. How many tickets of each type were sold?

Let x = number of $3 tickets

Let y = number of $2 tickets

Total = quantity × value

quantityvaluetotal$3 ticketsx33x$2 ticketsy22ytogether350950

Step 3: Add down each column to get the equations

x + y = 350                    (equation 1)

3x + 2y = 950                (equation 2)

Use Substitution Method

Isolate variable x in equation 1

x = 350 – y                     (equation 3)

Substitute equation 3 into equation 2

3(350 – y) + 2y = 950

1050 – 3y + 2y = 950

3y – 2y = 1050 – 950

y = 100

Substitute y = 100 into equation 1

x + 100 = 350

x = 250

Answer: 250 $3 tickets and 100 $2 tickets were sold.

Answer:

See Below.

Step-by-step explanation:

We want to verify the equation:

[tex]\displaystyle \frac{\tan\theta}{ 1- \cot \theta} + \frac{\cot\theta}{1 - \tan\theta} = \frac{\dfrac{\sin\theta}{\cos\theta}}{1 - \dfrac{\cos\theta}{\sin\theta}} + \frac{\dfrac{\cos\theta}{\sin\theta}}{1 - \dfrac{\sin\theta}{\cos\theta}}[/tex]

Recall that tanθ = sinθ / cosθ. Likewise, cotθ = cosθ / sinθ. Then by substitution:

[tex]\displaystyle \begin{aligned} \frac{\tan\theta}{ 1- \cot \theta} + \frac{\cot\theta}{1 - \tan\theta} & = \frac{\dfrac{\sin\theta}{\cos\theta}}{1 - \dfrac{\cos\theta}{\sin\theta}} + \frac{\dfrac{\cos\theta}{\sin\theta}}{1 - \dfrac{\sin\theta}{\cos\theta}} \\ \\ & \stackrel{\checkmark}{=} \frac{\dfrac{\sin\theta}{\cos\theta}}{1 - \dfrac{\cos\theta}{\sin\theta}} + \frac{\dfrac{\cos\theta}{\sin\theta}}{1 - \dfrac{\sin\theta}{\cos\theta}} \end{aligned}[/tex]

Hence verified.

Given :

tan∅/1-cot∅ + cot∅/1-tan∅ = sin∅/cos∅ ÷ (1- cos∅/sin∅ ) + cos∅/sin∅ ÷ (1 - sin∅/cos∅)

To Do :-

To prove LHS = RHS

Proof :-

We know that ,

sin∅/cos∅ = tan∅cos∅/sin∅ = cot∅

On using above two in LHS ,

LHS = tan∅/1-cot∅ + cot∅/1-tan∅LHS = tan∅/1-cot∅ + cot∅/1-tan∅ = sin∅/cos∅ ÷ (1- cos∅/sin∅ ) + cos∅/sin∅ ÷ (1 - sin∅/cos∅) LHS = RHS

Hence proved !
