For the first two, multiply 13 in place of the X. For example, 4(13)+71 = 123.

Tom purchased international calling cards before traveling abroad. He bought a 60-minute card for $9.99, a 90-minute card for $1

SpyIntel [72]

The amount spent on calls per minute is an illustration of unit rates.

The amount spent on the 38-minute call is $113.62

The given parameters are:

$\mathbf{Rate = \$2.99/minute}$

$\mathbf{Time = 38\ minutes}\\$

So, the amount spent on call is:

$\mathbf{Amount = Rate \times Time}$

This gives

$\mathbf{Amount = \$2.99/minute \times 38\ minutes}$

Cancel out minutes

$\mathbf{Amount = \$2.99 \times 38}$

$\mathbf{Amount = \$113.62}$

Hence, the amount spent on the 38-minute call is $113.62

A right triangular prism has a height of 3 ft, a width of 4 ft, and a hypotenuse of 5 ft. The depth of the triangle is missing.

DiKsa [7]

Depth=15
x=(height(h)*width(w)*hypotenuse(y))/2
x=(3*4*5)/2=(60/2)=30
y=(x(x-h)(x-w)(x-y))^(1/2)
f=(-h^4+2(hw)^2+2(wy)^2-w^4+2(hy)^2-y^4)^(1/2)
f=(-3^4+2(3*4)^2+2(4*5)^2-4^4+2(3*5)^2-5^4)^(1/2)
f=576^(1/2)
f=24
Surface Area= 2f(.5)+(h+w+y)*depth
192=depth*(3+4+5)+24(.5)
180=(3+4+5)*depth
180=(12)(depth)
15=depth

4. What kind of triangle is made by connecting the points A(0, –6), B(3, –6), and C(3, –2)?

Firdavs [7]

Answer:

Part 4) Right triangle

Part 5) Kite

Step-by-step explanation:

Part 4) What kind of triangle is made by connecting the points A(0, –6), B(3, –6), and C(3, –2)?

Using a graphing tool

see the attached figure N $1$

The triangle of the figure is not equilateral------> The triangle does not have three equal sides

The triangle of the figure is a right triangle------>The triangle has an angle of $90\°$

The triangle of the figure is not isosceles------> The triangle does not have two equal sides

The triangle of the figure is not a right and isosceles

Part 5) What type of quadrilateral is formed by connecting the points $(0, 9), (3, 6), (0, 1), and (-3, 6)$ ?

Using a graphing tool

see the attached figure N $2$

The figure is not a rhombus------> All sides are not congruent

The figure is not a trapezoid-----> has not parallel sides

The figure is a kite------> Two disjoint pairs of consecutive sides are congruent and the diagonals meet at a right angle
