Find the product.<br><br> (23)(−98)(−45)(−1)<br> Enter the correct product in the box.

torisob [31]

Answer:

-101,430

Step-by-step explanation:

23 x 98 x 45 x 1 equals 101,430, but the real trick of the question is whether it is positive or negative.

23(-98) forms a negative number (-2,254)

-2254(-45) forms a positive number (101,430)

101,430(-1) forms a negative number (-101,430)

zloy xaker [14]

Answer:

a. $\frac{3}{5}(7)\text{ or }\frac{3\times 7}{5}$

b. $\frac{1}{6}(4\times 8)\text{ or }\frac{4\times 8}{6}$

Step-by-step explanation:

In numerical expressions we write numbers with the mathematical symbols ( i.e. '+', '-' etc )

a. Given phrase,

Three fifths of seven,

$\frac{3}{5}(7)$

$=\frac{3\times 7}{5}$

$=\frac{21}{5}$

$=4\frac{1}{5}$

b. One sixth the product of four and eight,

$\frac{1}{6}(4\times 8)$

$=\frac{4\times 8}{6}$

$=\frac{32}{6}$

$=5\frac{1}{3}$

Consider the graphs of the functions f(x) and g(x)...

IRINA_888 [86]

Answer:

As per graphs, f(x) is a quadratic function and g(x) is an exponential function.

At x = 1 both the functions have same value of 6.

At x > 1 the exponential function has a greater rate of growth.

The answer is g(x).

Answer:

72 cupcakes

Step-by-step explanation:

Morgan can make 4 cupcakes with one cup of flour. She has 18 cups of flour and suppose she can make x cupcakes, then

1 cup of flour - 4 cupcakes

18 cups of flour - x cupcakes

Write a proportion:

$\dfrac{1}{18}=\dfrac{4}{x}$

Cross multiply:

$1\cdot x=18\cdot 4\\ \\x=72\ cupcakes$

Suppose two angles are supplementary and one of them measures 31 degress what is the measure of the other angle

Nady [450]

Supplementary means it adds up to 180 degrees.
So if one side is 31 degrees, you would need to subtract that from 180 to find the other side.
-----------------------
180 - 31 = 149
-----------------------
The other angle would be 149 degrees.
