Answer:

17/50

Step-by-step explanation:

P(red or purple) = number of red or purple / total

There are 7 red rings and 10 purple rings

                          = (7+10) / 50

                          = 17/50

17/50
There are 7 red rings, and there are 10 purple rings, If you add all the rings together, it is out of 50, therefore it is 17/50

request :- If you are helped with my answer pls tag me brianliest I really want it... Plzz

THANK YOU............. Pls see to my request

Answer:

9 3/2

Step-by-step explanation:

substitute the given value of X into the equation 2y=X-6

2y=9-6

solve for y

y=3/2

The possible ordered pair of the system is the ordered pair (x,y)

(x,y)=(9, 3/2)

check the given ordered given pair is the system of equations

2 ×3/2=9-6

simplify the equality

9=9

3=3

since all the equalities are true,the ordered pair is the solution of the system

(x,y) =(9 3/2)

A picnic basket was marked up 95% from an original cost of $9.57. Last Friday, Rosanne bought the picnic basket and paid an additional 8% in sales tax. What was her total cost?

Answers

Answer: $10.60

Step-by-step explanation:

Turn 95% into a decimal then add $9.57, then turn 8% into a decimal then add all of the numbers together.

I'm not sure if this is right, I did it on my own.

The total cost to be paid is $20.15

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

Original cost =  $9.57

Markup= 95%

So, the new cost of the basket

=95/100 x 9.57

=0.95 x 9.57

=$9.0915

Thus, the cost of the basket is

= 9.57+9.0915

=18.66

Also, the sales tax is 8%

=8/100 x 18.66

=0.08 x 18.66

=1.4928

Therefore, the total amount to be paid is

=18.66+1.4928

=$20.15

In the course of a short race, a car does 50,000 J of work in 7 s. What is the power of the car during the race? (round to the nearest whole number)

Answers

Answer:

Work done is the product of distance and force, it is measured in joules.

Power is the rate of work done given by dividing the work done by time

Power (watts)= workdone (J)/ time (s)

                     = 50,000J/7 sec

                     = 7142.857 watts

Therefore, the power of the car during the race was 7142.857 watts

The goalie on the Iceblades hockey team saves (blocks) 73% of the opponent's shots. With 10 minutes to go, the Iceblades are ahead by one goal, and they will win if the other team does not score.
The other team takes 5 shots in the final 10 minutes. The Iceblades do not score any more goals.
The table shows pairs of random digits. The pairs in each group simulate the 5 shots taken by the opponent.
Answer the questions to estimate the probability that the Iceblades will win the game.

a. 8.7cm

b. 43.5cm squared

Step-by-step explanation:

a. draw the triangle with a side length of 10cm, and measure the height which is 8.7cm.

b. formula to find the area  of a triangle: (base into height) divided by 2 ((b x h) / 2)

the base is 10

the height is 8.7

Let’s find the slope of this equation

Slope formula:

(y2-y1/x2-x1)

Plug things in

(-3000-0/20-0)

(-3000/20)

Condense the fraction

Slope = -150 or lowering 150 feet per minute.

Let’s get point slope form, add in some points.

Point slope form:

y - y1 = -150(x - x1)

Plug things in

y - (-3000) = -150(x - 20)

y + 3000 = -150x + 3000

Subtract 3009

y = -150x

Plug in -36000 for y

(-36000) = -150x

Divide by -150

x = 240

You are correct, it took 240 minutes.

Key to a lock= 1264

Step-by-step explanation:

Sorry for the wait I just saw this question. Lol, I guess answer 1 is always equal to answer two but here is my work:

6(3)+21(4)=18+84=102

2(2(3)+7(4)=2(6+28)=12+56=102

5(6)x7(6)=30+42+72

6(5+7)=6(12)=72

14(10)+2=140+2=142

2(7(10)+1)=2(70+1)=2(71)=142

102+102+72+72+142+142=632

632 squared means 632x2 which is 1264.

Solve the system of equations by substitution.

-8x+2y=4
y=4x+2

Answers

Answer:

the answer by substitution would be y = 4x+2

Correct answer: Infinite solution because 2 = 2.

Set the first equation equal to y.

-8x + 2y = 4

+8x          +8x

___________

2y = 8x + 4

__   ___  __

2      2     2

y = 4x + 2

At this step, you can choose any equation to substitute into the other equation. However, I'm going to substitute the new first equation with the second equation where y is. Solve for x.

y = 4x + 2

4x + 2 = 4x + 2

-4x        -4x

____________

2 = 2

So, at this point, we know the system of equation does not have one solution. Thus, when the same number equals the same number, it is an infinite solution.

We can prove this by an online graphing tool. Insert the two equations onto the online graphing tool. If the lines appear to be on the same line, they have infinite solutions. Hope this helps :) Let me know if you have any questions related to this problem!

The measures of the angles of a triangle are shown in the figure below. Solve for x

Answers

x is equivalent to 6

ok yeah I can find what the name is but how in the heck do I find the value of x?!!! directions in photo no links or your getting reported!!!!!

Answers

This is an isosceles triangle, as indicated by the two lines on two sides (they are equal). One angle is 45 degrees, as indicated. We know that the angles of the two equal sides are equal as well. Knowing that all triangles sum up to 180 degrees, we can subtract 45 from 180 and divide by two to get each equal angle.

Here it is:

180-45=135

135 divided by 2 is 67.5.

This means that the value of x is 67.5 degrees.

To check, we can add all of the sums and it should be 180 degrees.

45+67.5+67.5=180

∴ x= 67.5 degrees

Take what a triangle equal up to them subtract 45
