Because one angle is shared between the smaller and larger triangles, this angle is clearly equal.  In addition, their sides surrounding that angle are in the same ratio, so these triangles are similar by SAS similarity, with a ratio of 2.  This means the sides of the big triangle are twice as long as the ones of the small triangle.  As a result, x is equal to 46*2=92.

The costs of the digital Camera is $185.00 dollars The sales tax rate is said to be 5.7%. Now, let’s solve for the final price by simply adding 5.7% to the original price. Solutions: => 185 dollars – original price => 5.7% - sales tax => 5.7% = 5.7 / 100 = .057 Let’s get the 5.7% value => 185 * .057 = 10.545 Now, we have the value, let’s add this to the original price of the camera => 185 + 10.545 = 195.545 Thus, the final price with the sales tax is 195.55 ANSWERED AT 14/12/2019 - 05:35 PM QUESTION POSTED AT 14/12/2019 - 05:35 PM ### Jack shells 315 peanuts in 15 minutes 315 peanuts/ 15 min= 21 peanuts/min.

### On a test, 1 point is given for each correct answer and 1 point is deducted for each incorrect answer. On the test Harold answered 34 items correctly and 6 items incorrectly. What two numbers can be used to find Harold's total score

Forgive me if I'm wrong, but here goes:

On Harold's test, he scores 34 points for his correct answers, and -6 points for incorrect answers. He would have gotten 28 points, but that's not the question.

34 is the first number, and I believe the next one is -6.
6 is negative because 1 point is deducted for each incorrect answer, which also means 1 point is subtracted for every incorrect answer. Because the question is asking for numbers and not an equation or expression, the subtraction is expressed as a negative symbol, hence negative six.

Hope I helped!
