Quadrilateral SQUA is a square with sides measuring 25mm. Quadrilateral AQER is also a square.What is the length diagonal RQ

svet-max [94.6K]

The square has 4 sides of the same measure.

If square SQUA has a side measuring 25 mm, it means side QU measures the same.

Also, if quadrilateral AQER is a square two, then its diagonals bisect each other, then QU is equal to UR.

Thus, QR measures:

$\begin{gathered} QR=QU+UR \\ QR=25\operatorname{mm}+25\operatorname{mm} \\ QR=50\operatorname{mm} \end{gathered}$

The answer is 50 mm

Find a1 if Sn = 89,800, r = 3.4, and n = 10. Round to the nearest hundredth if necessary.

Answer:

$a_1=1.04$

Step-by-step explanation:

We have a geometric sequence with:

$Sn = 89,800$ , $r = 3.4$ , and $n = 10$

Where

Sn is the sum of the sequence

r is the common ratio

$a_1$ is the first term in the sequence

n is the number of terms in the sequence

The formula to calculate the sum of a finite geometric sequence is:

$S_n=\frac{a_1(1-r^n)}{1-r}$

Then:

$89,800=\frac{a_1(1-(3.4)^{10})}{1-3.4}$

Now we solve for $a_1$

$89,800(1-3.4)=a_1(1-(3.4)^{10})$

$a_1=\frac{89,800(1-3.4)}{1-(3.4)^{10}}\\\\a_1=1.04$

hichkok12 [17]

Answer:

105 boys

Step-by-step explanation:

At a local preschool there is a ratio of 3 boys to 4 girls.

i.e boys:girls = 3:4

There are 245 preschoolers enrolled.

Number of boys = $\frac{3}{7}$ × 245 = 105 boys
