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.

You ordered two digital cameras online that cost $364 each.edhelper offers a 15% discount off the digital camera.You pay no tax,but the total shipping charge for the order $9.97. What is the total to pay?

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

QUESTION POSTED AT 14/12/2019 - 05:32 PM

What is the slope-intercept form of the function that contains the point (–1, 5) and has a slope of –4?

Slope intercept form equation:

y=mx+C

----------------------

We already know that m=-4. Now, let's find the value of C.

--------------------

m=-4, and when x=-1, y=5.

(5)=(-4)*(-1)+C

5=4+C

5-4=4+C-4

1=C

-----------------

Therefore the slope intercept form of the function is:

y=-4x+1

Greta bought three 15-pounds bags of dry dog food.Her dog eats 10 ounces of dry dog food each day.After how many days will Greta need to buy more dog food?

Answer:  Greta needs to buy more dog food after 72 days.

Step-by-step explanation:  Given that Greta bought three 15-pounds bags of dry dog food and her dog eats 10 ounces of dry dog food each day.

We are to find the number of days after which Greta need to buy more dog food.

We know that

\textup{1 pound}=16~\textup{ounces}\\\\\Rightarrow \textup{3\times 15 pounds}=16\times3\times15=720~\textup{ounces}.

Let Greta needs to buy more dog food after x days.

Then, according to the given condition, we have

10\times x=720\\\\\Rightarrow 10=\dfrac{720}{10}\\\\\Rightarrow x=72.

Thus, Greta needs to buy more dog food after 72 days.

QUESTION POSTED AT 14/12/2019 - 05:01 PM

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!
