Answer: 45 Pennies and 15 Nickels

Step-by-step explanation:

0.05 x 15 = 0.75

0.01 x 45 = 0.45

0.45 + 0.75 = 1.20

Answer:

B. 1

Step-by-step explanation:

The 40° angle and the fixed side lengths of 10 cm and 8 cm uniquely determine the locations of Points A and B.

Thus, you can construct only one triangle using these measurements.

Step-by-step explanation:

Area of a trapezoid = (a+b)*h/2 so (100+150)*80/2

= 10000

Area of a rectangle = l*w so 48*64

=3072

10000-3072 = 6928

The surface area of a square pyramid is A=a^2+2a√a^2/4+h^2 which is A=4^2+2(4)√(4)^2/4+(5)^2 which = 59.08

Volume of a rectangular prism is l*w*h so 3.5*1.25*6 = 26.25 which is equal to 26 1/4

A caterpillar started at point (−2.5, −5.5) on a coordinate plane. She crawled in a straight line through the origin to point (4

alexgriva [62]

Answer:

The value of y is $99$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem the line passes through the origin

therefore

Is a proportional variation

Find the value of k

with the point $(-2.5,-5.5)$

$k=y/x=-5.5/-2.5=2.2$

The equation is equal to

$y=2.2x$

so

For $x=45$

substitute

$y=2.2(45)=99$
