Answer:

A

Step-by-step explanation:

Δ NLP and Δ NMO are similar, thus the ratios of corresponding sides are equal, that is

$\frac{NL}{NM}$ = $\frac{NP}{NO}$ , substitute values

$\frac{15+x}{15}$ = $\frac{28}{20}$ ( cross- multiply )

20(15 + x) = 420 ( divide both sides by 20 )

15 + x = 21 ( subtract 15 from both sides )

x = 6

A two-person relay race consists of eight times around a football field. Juan runs four and one-sixth times and Antonio runs thr

Serga [27]

Answer:

A

Step-by-step explanation:

To convert mixed number as improper fractions, use this rule:

$A\frac{B}C}=\frac{(A*C)+B}{C}$

<u>For Juan:</u> ( $4\frac{1}{6}$ )

$4\frac{1}{6}=\frac{(4*6)+1}{6}=\frac{25}{6}$

<u>For Antonio:</u> ( $3\frac{2}{3}$ )

$3\frac{2}{3}=\frac{(3*3)+2}{3}=\frac{11}{3}$

Answer choice A is correct.

This net can be folded to make a square pyramid. what is the surface area of the pyramid

givi [52]

Answer:

$85in^2$

Step-by-step explanation:

to find the surface area we need to find the followng areas:

area of the square

area of a triangle and multiply it by 4 (because there are 4 triangles)

And once we have those areas, we add them to find the surface area.

Area of the square:

the formula to find the area of a square is:

$a_{square}=l^2$

where $l$ is the length of the side: $l=5in$

thus the area of the square is:

$a_{square}=(5in)^2$

$a_{square}=25in^2$

Area of the triangles:

the are of 1 triangle is given by

$a_{triangle} =\frac{b*h}{2}$

where $b$ is the base of the triangle: $b=5in$ (the base of the triangle is the side of the square)

and $h$ is the height of the triangle: $h=6in$

thus, the area of 1 triangle is:

$a_{triangle} =\frac{(5in)*(6in)}{2}$

$a_{triangle} =\frac{30in^2}{2}$

$a_{triangle} =15in^2$

the area of the 4 triangles is (we multiply by 4):

$a_{4-triangles}=4(15in^2)$

$a_{4-triangles}=60in^2$

finally we add the area of the square and the area of the 4 triangles to find the total surface area:

$Surface=25in^2+60in^2$

$Surface=85in^2$
