Triangle ABC was dilated using the rule Do.4. Triangle

pshichka [43]

Answer:

The correct option is B. The length of OB' is 3 units.

Step-by-step explanation:

The rule of dilation is D₀,₄. It means dilation by scale factor 4 with center of dilation is origin.

$\text{Scale factor}=\frac{\text{Distance between center and any point of the image}}{\text{Distance between center and corresponding point of the Preimage}}$

$\text{Scale factor}=\frac{OB'}{OB}$

$4=\frac{OB'}{\frac{3}{4}}$

$4\times \frac{3}{4}=OB'$

$3=OB'$

The length of OB' is 3 units. Therefore the correct option is option is B.

What is the recursive formula for this sequence?

Vikki [24]

Answer:

B) $a_1=6$ and $a_n=a_{n-1}+5$

Step-by-step explanation:

The given sequence is 6, 11, 16, 21,...

The common difference is d=11-6=5

The first term in the sequence is $a_1=6$

The recursive formula for an arithmetic sequence is given as:

$a_n=a_{n-1}+d$

Substitute the above information to get:

$a_n=a_{n-1}+5,\:\:a_1=6$

In August, Nancy's Clothing Store sold 266 shirts with the ratio of short sleeve to long sleeve being 4:10. How many short sleev

Akimi4 [234]

Answer:

The number of short sleeve sold was 76

Step-by-step explanation:

Let

x ----> the number of short sleeve sold

y ----> the number of long sleeve sold

we know that

$\frac{x}{y}=\frac{4}{10}$

$x=\frac{4}{10}y$ -----> equation A

$x+y=266$ -----> equation B

substitute equation A in equation B

$\frac{4}{10}y+y=266$

solve for y

$\frac{14}{10}y=266\\\\y=266(10)/14\\y=190$

Find the value of x

$x=\frac{4}{10}(190)=76$

therefore

The number of short sleeve sold was 76
