Ja'Kiree has a bunch of quarters and nickels in her piggy bank totaling $8.75. If Ja'Kiree has 26 quarters, how many nickels doe

evablogger [386]

Start off by stating your facts. You have a maximum of $8.75. We know that each quarter is 25 cents so we multiply 25x26 equaling 650. Yet we need a decimal so it would be $6.50. Each nickel is worth 5 cents so then you would minus $8.75 and $6.50 getting us to $2.25. Now divide it by 5 cents and you should get 45 nickels. You can also do this by stating that 10 nickels is 50 cents and go until you get 45

Effectus [21]

Answer:

62 degrees, or A, is the answer

Step-by-step explanation:

combine expressions : 3x - 42 = 180

Then : 3x = 222

x = 74

74 - 12 = 62

the verticales of triangle XYZ are X(-3,-6),Y(21,-6),and Z(21,4). What is the perimeter of the triangle

andrezito [222]

Answer:

<h2>P = 60</h2>

Step-by-step explanation:

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

X(-3, -6), Y(21, -6). Substitute:

$XY=\sqrt{21-(-3))^2+(-6-(-6))^2}=\sqrt{24^2+0^2}=\sqrt{24^2}=24$

X(-3, -6), Z(21, 4). Substitute:

$XZ=\sqrt{(21-(-3))^2+(4-(-6))^2}=\sqrt{24^2+10^2}=\sqrt{576+100}=\sqrt{676}=26$

Y(21, -6), Z(21, 4). Substitute:

$YZ=\sqrt{(21-21)^2+(4-(-6))^2}=\sqrt{0^2+10^2}=\sqrt{10^2}=10$

The perimeter of the triangle XYZ:

$P_{\triangle XYZ}=XY+XZ+YZ$

Substitute:

$P_{\triangle XYZ}=24+26+10=60$

The figure is made up of a rectangle and 2 right triangles.

Softa [21]

Answer:

Total area of the figure is 1259 units² .

Step-by-step explanation:

Formula

$Area\ of\ triangle = \frac{1}{2}\times Base\times Height$

Area of a rectangle = Length × Breadth

As given

In triangle

Base = 9 unit

Height = 34 unit

In rectangle

Length = 28 unit

Breadth = 34 unit

In another triangle

Base = 11 unit

Height = 28 unit

Thus

Total area = Area of a rectangle + Area of first triangle + Area of second triangle .

$Total\ area = 28\times 34 + \frac{1}{2}\times 9\times 34 +\frac{1}{2}\times 11\times 28$

$Total\ area = 952 + \frac{306}{2} + \frac{308}{2}$

Total area = 952 + 153 + 154

Total area = 1259 units²

Therefore the total area of the figure is 1259 units² .
