Answer:

The height of the triangle is 3.2 cm.

Step-by-step explanation:

The area of the triangle = $16 cm^2$

Base of the triangle = 10 cm

Height of the triangle = h cm

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

$16 cm^2=\frac{1}{2}\times 10 cm \times h$

h = 3.2 cm

The height of the triangle is 3.2 cm.

What type of number is -16.2i

azamat

Answer:

Complex and imaginary number

Step-by-step explanation:

First, let's write the number $-16.2i$ in the form of $a+bi$ .

$0+ (-17)i$

Since $-16.2i$ can be written in the form of $a + bi$ , where $a$ and $b$ are real numbers, it is a complex number.

Also, since $a=0$ , it is also an imaginary number.

$-16.2i$ is complex and imaginary.

Which function has the least value for the y-intercept?

diamong [38]

Answer:

y-intercept is the value of y when x is equal to zero. Because the y intercept is a point on a graph, you'll usually write it in point/ coordinate form.

Step-by-step explanation:

The y-intercept is where the parabola of a function crosses (or intercepts) the y axis.

michelle bought the same fabric on 3 different occasions and recorded the data below what was the price per yard of fabric? answ

bazaltina [42]

Please consider the complete question.

Michelle bought the same fabric on 3 different occasions and recorded the data below.

Yards of Fabric Total Cost

2.2 $2.53

3.6 $4.14

4.2 $4.83

What was the price per yard of fabric?

To find the cost per yard of fabric, we will divide cost of yards by number of yards.

$\text{Cost per yard}=\frac{\text{Cost}}{\text{Number of yards}}$

$\text{Cost per yard}=\frac{\$2.53}{2.2\text{ yards}}$

$\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}$

Let us find cost per yard using 2nd set of data.

$\text{Cost per yard}=\frac{\$4.14}{3.6\text{ yards}}$

$\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}$

Similarly we will find cost per yard for 3rd set of data.

$\text{Cost per yard}=\frac{\$4.83}{4.2\text{ yards}}$

$\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}$

Therefore, the cost per yard of fabric is $1.15.

A 96 inch stick breaks into two pieces in the ratio of 3:5. How big is each piece?

Svetlanka [38]

40 cm.

let the length of the first part be 3x, second part be 4x, third part be 5x.

where x is a positive length in cm.

why 3x,4x and 5x ?

so that the ratio of lengths of the 3 parts be 3:4:5.

total length of the stick = 3x + 4x + 5x = 12x=96cm

so x=96/12 = 8cm

therefore the largest part of the stick (5x)= 5*8 =40cm
