15% of 25 is the greatest of the two.

Answer:

25% of 15 is 3.75

15% of 25 is also 3.75

15 - 3.75 = 11.25

25 - 3.75 =21.25

Compare and then determine.

11.25 < 21.25

Answer: 25% x 15=25/100 x 15=.25 x 15=3.75

15% x 25=15/100 x 25=.15 x 25=3.75

Now you can clearly see that they are the same.

Answer:

C = 100p + 200

Step-by-step explanation:

Because C is the total cost per day, 200 is the y-intercept because it's paid daily.

The 100 is the slope since "he pays a cost of $100 per phone produced)".

PART A: Mrs. konsdorf claims that angle R is a right angle.Is Mrs. konsdorf correct? explain your reasoning PART B: if T is trab

Anna007 [38]

Answer:

Part A: Angle R is not a right angle.

Part B; Angle GRT' is a right angle.

Step-by-step explanation:

Part A:

From the given figure it is noticed that the vertices of the triangle are G(-6,5), R(-3,1) and T(2,6).

Slope formula

$m=\frac{y_2-y_1}{x_2-x_1}$

The product of slopes of two perpendicular lines is -1.

Slope of GR is

$\text{Slope of GR}=\frac{1-5}{-3-(-6)}=\frac{-4}{3}$

Slope of RT is

$\text{Slope of RT}=\frac{6-1}{2-(-3)}=\frac{5}{5}=1$

Product of slopes of GR and RT is

$\frac{-4}{3}\times 1=\frac{-4}{3}\neq -1$

Therefore lines GR and RT are not perpendicular to each other and angle R is not a right angle.

Part B:

If vertex T translated by rule

$(x,y)\rightarrow(x-1,y-2)$

Then the coordinates of T' are

$(2,6)\rightarrow(2-1,6-2)$

$(2,6)\rightarrow(1,4)$

Slope of RT' is

$\text{Slope of RT'}=\frac{4-1}{1-(-3)}=\frac{3}{4}$

Product of slopes of GR and RT' is

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

Since the product of slopes is -1, therefore the lines GR and RT' are perpendicular to each other and angle GRT' is a right angle.

What is the measure of the indicated angle? A 180° B 110° C 70° D 90°

ikadub [295]

Answer:

D. 70°

Step-by-step explanation:

the sum of the unknown angle and 110° is 180 °

so, let the unknown angle be x

x+110 = 180

x = 180-110

x = 70°

Constant of Proportionality = d/t = 90/2 = 45 mph

In short, Constant of Proportionality would be: 45 miles per hour.

Here, d/t = 45
d = 45t

In short, Your Equation would be: d= 45t

Hope this helps!
