30.50-14= 16.50
16.50 divided by 2.75= 6
The answer is 6

Answer:

Step-by-step explanation:

6). Surface area of a triangular prism = Area of the triangular bases + (Perimeter of the triangular base)×height

Area of one triangular base = $\frac{1}{2}(\text{Base})(\text{Height})$

= $\frac{1}{2}\times 4\times 3$

= 6 km²

Perimeter of the triangular base = (4 + 3 + 5)

= 12 km

Height of the triangular prism = 7 km

Surface area of the given triangular prism = 2(6) + (12)(7)

= 12 + 84

= 96 km²

7). Surface area of a rectangular prism = 2(lb + bh + hl)

Here, l = Length, b = Width and h = Height

By substituting the values from the given question,

l = 9 in, b = 9 in, h = 4 in

Surface area of the rectangular prism = 2(9×9 + 9×4 + 4×9)

= 2(81 + 36 + 36)

= 2(153)

= 306 in²

How do you model a situation in which a function behaves differently over different parts of its domain?

Eduardwww [97]

The situation in which a function behaves differently over different parts of its domain is modeled by considering it to be a piecewise function.

Such a situation can be explained through an example:

f(x)= { 2x, for x > 0

{ 1, for x = 0

{ -2x, for x < 0

now, when we take x value less than 0, say x= -1

thus, f(x)= f(-1)= -2(-1) = 2 , here we used f(x) given x<0

now, when we take x value more than 0, say x= 2

thus, f(x)= f(1)= 2(1) = 2, here we used f(x) given x>0

now, when we take x = 0,

thus, f(x)= f(0)= 1, here we used f(x) given x=0

this is how we model picewise function, we use f(x) as per the value of x. Following image shows plotted answer for this example.

Since inequalities given are exclusive of 0, we leave the dot at the origin unfilled. Now, for x = 0. Since the value is constant at f(x) =1, we plotted a point at (0,1)

50 POINTS+BRAINLIEST!!!!

Ilya [14]

Answer: So, we know that the internal angles of a triangle add up to 180 degrees, yes?

60 degrees plus 50 degrees equals 110 degrees, and subtract 110 from 180, and you get 70 degrees for angle y.

Now, if the triangles are congruent (identical) and the shape you are describing is like an hourglass, then because of the vertical angles theorem, angle x should be 70 degrees too!

Brainliest please if I am correct! and hope it helped.

Briana has 4 1/2 cups of oats. She uses 2 1/4 cups of oats to make oatmeal- raisins cookies, then borrow 1 cup of oats from her

insens350 [35]

Answer:

She has enough with $\frac{3}{4}$ cups left over.

Step-by-step explanation:

For this equation, it's probably easiest to use improper fractions.

At the start, she has 4 $\frac{1}{2}$ cups, or $\frac{9}{2}$ , which can be converted to $\frac{18}{4}$ (which is useful for the next part) by multiplying the numerator and denominator by 2.

When she uses 2 $\frac{1}{4}$ cups, which can be converted to $\frac{9}{4}$ . When subtracting this from the original, you get $\frac{18}{4}$ - $\frac{9}{4}$ = $\frac{9}{4}$ .

She borrows another cup, or $\frac{4}{4}$ of a cup, which gets added on to the previous result, giving $\frac{9}{4}$ + $\frac{4}{4}$ = $\frac{13}{4}$ .

The recipe calls for 2 $\frac{1}{2}$ cups, which can be converted to $\frac{5}{2}$ or $\frac{10}{4}$ .

$\frac{13}{4}$ - $\frac{10}{4}$ = $\frac{3}{4}$ , meaning she has $\frac{3}{4}$ cups left over.

** solving this mainly uses conversion to improper fractions and adding/subtracting fractions, which may be skills you would like to practice. I'm always happy to help!

Solve for x write the smaller solution first and the larger solution second. Round to two decimal places (x+8)^2-7=0

siniylev [52]

Answer:

x ≈ - 10.65, x ≈ - 5.35

Step-by-step explanation:

Given

(x + 8)² - 7 = 0 ( add 7 to both sides )

(x + 8)² = 7 ( take the square root of both sides )

x + 8 = ± $\sqrt{7}$ ( subtract 8 from both sides )

x = - 8 ± $\sqrt{7}$ , thus

x = - 8 - $\sqrt{7}$ ≈ - 10.65

x = - 8 + $\sqrt{7}$ ≈ - 5.35
