Answer: Choice 1) triangle DEF is similar to triangle BAC because corresponding angles are congruent. Ratio is 1/2

D = 53, B = 53 are two angles that are congruent and pair up.

So are E = 58 and A = 58. They pair up as well.

Finally, F = 69 and C = 69 pair up

We get triangle DEF is similar to triangle BAC. The order of the letters matters.

If we start with triangle BAC, and cut each side in half, then we get the corresponding sides of triangle DEF. For example, BA = 6.2 goes to DE = 3.1

strojnjashka [21]

Answer:

After 11 weeks, Darnell′s savings account will have a total of $8,360.

Step-by-step explanation:

The data provided is as follows:

   n:    1        2       3        4

f (n): 260   360   460   560  

Consider the data for f (n).

The series f (n) follows an arithmetic sequence with a common difference of 100 and first term as 260.

The nth term of an arithmetic sequence is:

a_{n}=\frac{n}{2}[2a+(n-1)d]

Compute the value of f (11) as follows:

f(11)=\frac{11}{2}[(2\times260)+(11-1)\times 100]

        =5.5\times[520+1000]\\\\=5.5\times 1520\\\\=8360

Thus, after 11 weeks, Darnell′s savings account will have a total of $8,360.

A museum has 450 visitors each day. If they are open 5 hours, how many people do they see per hour?
il63 [147K]

Answer: 90 visitors per hour

Explanation: "Per hour" means in 1 hour, so we can rewrite the given statement using fractions as <em>450 visitors/5 hours = __visitors/1 hour</em>.

To find out what goes in the bank, notice that we

have a 1 in the denominator of our second fraction.

So we want to find a fraction that is equivalent

to 450/5 that has a 1 in the denominator.

If we divide the numerator and denominator of 450/5 by 5,

we get the equivalent fraction 90/1 or <em>90 visitors/1 hour</em>.

So now we have <em>90 visitors/1 hour = __visitors/1 hour</em>.

So a 90 must go in the blank.

This means that the museum sees 90 visitors per hour.
