Kinda left explainitory but I need help with finding the base

almond37 [142]

Answer:

6.4 cm

Step-by-step explanation:

Area of triangle = 17.28 cm²

$\frac{1}{2}*base *altitude = 17.28\\\\\frac{1}{2}*base*5.4=17.28\\\\base = 17.28*\frac{2}{5.4}\\\\base= 3.2*2\\\\base = 6.4 cm$

A store sold 40 more basketballs than soccer balls last month.

blsea [12.9K]

Answer:

soccer balls = 80

basketballs = 120

Step-by-step explanation:

let S = number of soccer balls sold

let B = number of basketballs sold

If the store sold 40 more basketballs than soccer balls, then

B = S + 40

If the store sold $4800 worth of soccer and basketballs last month at a cost of $33 for a soccer ball and $18 for a basketball, then:

33S + 18B = 4800

Substitute the first equation B = S + 40 into the second equation and solve for S:

33S + 18(S + 40) = 4800

33S + 18S + 720 = 4800

51S + 720 = 4800

51S = 4080

S = 80

Substitute S = 80 into B = S + 40 to find B:

B = 80 + 40 = 120

Part 1)

Step-by-step explanation:

If you are mentioning about the window view on the graphing calculator, then you must be note that viewing window is the part of the coordinate plane that would be visible on the screen of your graphing calculator.

If you are just viewing only a small portion of entire graph, just think of your calculator screen as a magnifying glass, enabling you to view you a piece of the entire graph.

The size of the coordinate plane is interpreted by Xmin, Xmax, Ymin, and Ymax, as seen at the left.

The zoom setting should be such that you can get the decent range for the x-values and y-values to determine the solution.

The Zoom setting 'Zstandard' is normally 10 x 10 window which is large enough to display the appropriate portion of the graph.

"ZFit" - recalculates Ymin and Ymax using current x-values to show best possible graph. The range gets adjusted so that the function will enter the window at a corner on the left side.

Part 2) Determining the solution of $x\:+\:4y\:=\:26;\:3x\:-\:4y\:=\:30$

Step-by-step explanation:

Considering the system of equations

$\begin{bmatrix}x+4y=26\\ 3x-4y=30\end{bmatrix}$

$x+4y=26$

$\mathrm{Subtract\:}4y\mathrm{\:from\:both\:sides}$

$x+4y-4y=26-4y$

$x=26-4y$

$\mathrm{Subsititute\:}x=26-4y$

$\begin{bmatrix}3\left(26-4y\right)-4y=30\end{bmatrix}$

$78-12y-4y=30$

$78-16y-78=30-78$

$-16y=-48$

$y=3$

$\mathrm{For\:}x=26-4y$

$\mathrm{Subsititute\:}y=3$

$x=26-4\cdot \:3$

$x=14$

$\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}$

$y=3,\:x=14$

The graph of the solution of the system of equation is also attached below.

The parking space shown at the right has an area of 209 ft2. A custom

jeyben [28]

Given:

The parking space shown at the right has an area of 209 ft².

A custom truck has rectangular dimensions of 13.5 ft by 8.5 ft.

To find:

Whether the truck fit in the parking space or not?

Solution:

If the area of the truck is more than the area of the parking space, then the truck cannot fit in the parking space otherwise it will fit in the parking space.

The area of a rectangle is:

$Area=length\times width$

Area of the rectangular truck is:

$Area=13.5\times 8.5$

$Area=114.75$

The area of the truck is 114.75 ft² which is less than the area of the parking space, 209 ft².

Therefore, the truck can fit in the parking space because the area of the truck is less than the area of the parking space.
