Answer:
Step-by-step explanation:
Given the area of the base of the oblique pentagonal pyramid is and the distance from the apex to the center of the pentagon is 6 cm. The measure of ∠ACB is 45°.
we know that
ABC is a right triangle
∠ACB=45°
AC=hypotenuse------> 6 cm
Now, volume of pyramid
Area of the base=50 cm²
so,
Given that the table shows the total miles Uyen has run this week.
The image of the table is attached below.
The total distance from the table is
The total distance this week is 1.5 times the distance that she ran last week.
We need to determine the number of miles that Uyen run last week.
<u>The number of miles Uyen run last week:</u>
Let x denote the number of miles that Uyen run last week.
Let us write the equation from the given data.
Thus, we have;
Dividing both sides by 1.5, we have;
Hence, the value of x is 14.8 miles.
Thus, Uyen ran 14.8 miles last week.
