find DC round to the nearest tenth

Answer:

5 cups of sugar

Step-by-step explanation:

add

Answer:

I think that it may be 33

Because, you see 15-9=6

so you do 20-9=11

Then you do 25-9=16

add them all together to get 33 so i think that's the perimeter

I am really not sure if this is correct...i'm kinda bad at stuff like this

Answer:

i think it is 122 degrees, as the solution would be to subtract 58 from 180

Step-by-step explanation:

180-58=122

angle1 = x

angle2 = x - 58

given,

these are supplementary angles

Therefore,

(x) + (x - 58) = 180

x + x - 58 = 180

2x - 58 = 180

2x = 180 + 58

2x = 238

x = 238/2

x = 119

angle1 = 119

angle1 = 119angle2 = 61

Given:

The equation is

[tex]\left(\dfrac{3}{5}\right)^x\left(\dfrac{5}{3}\right)^{2x}=\dfrac{125}{27}[/tex]

To find:

The value of x.

Solution:

We have,

[tex]\left(\dfrac{3}{5}\right)^x\left(\dfrac{5}{3}\right)^{2x}=\dfrac{125}{27}[/tex]

[tex]\left(\dfrac{5}{3}\right)^{-x}\left(\dfrac{5}{3}\right)^{2x}=\dfrac{5\times 5\times 5}{3\times 3\times 3}[/tex]      [tex][\because \left(\dfrac{a}{b}\right)^{-m}=\left(\dfrac{b}{a}\right)^{m}][/tex]

[tex]\left(\dfrac{5}{3}\right)^{-x+2x}=\dfrac{5^3}{3^3}[/tex]          [tex][\because a^ma^n=a^{m+n}][/tex]

[tex]\left(\dfrac{5}{3}\right)^{x}=\left(\dfrac{5}{3}\right)^{3}[/tex]

On comparing the exponents, we get

[tex]x=3[/tex]

Therefore, the value of x is 3.

Answer:

C: 108 Feet

Step-by-step explanation:

You just plug 3 in for t.

h(t) = -18(3)^2 + 18(3) + 216 = 0

-18(9) + 54 + 216 = 0

-162 + 54 + 216 = 0

-108 + 216 = 0

-108 + 216 = 108

So I believe I am correct.

Answer:

y=15x+5.50

Step-by-step explanation:

the y intercept or initial fee is 5.50 as written in the problem and the slope is 15 and a key word for that is each. meaning that y=15x+5.50

Answer:

8 rides

Step-by-step explanation:

20 + .50x = 24

-20             -20

.50x = 4

/.50    /.50

x = 8

Answer:

8

Step-by-step explanation:

If you have $24 and you buy a $20 ticket to get in, you are left with four dollars.

Since each ride is $0.50 and that is half a dollar, you can multiply four times two. This gives you eight.

Therefore, you can ride 8 rides :)

Answer:

the second one.

top right graph.

Step-by-step explanation:

Step-by-step explanation:

By Cosine rule, we have

s² = t² + u² - 2(t)(u)(cosS)

=> cosS = (t² + u² - s²)/2tu

=> cosS = (58² + 27² - 50²) / (2 * 58 * 27) = 0.5086.

Therefore S = cos^-1(0.5086) = 59.4° (1d.p.)

The measure of ∠S is 59.4°.

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

ΔSTU:

s = 50 inches

t = 58 inches

u = 27 inches

Applying the cosines rule on ΔSTU.

s² = t² + u² - 2 x t x u x cos S

cos S = (t² + u² - s²) / 2tu

cos S = (58² + 27² - 50²) / (2 x 58  x 27)

cos S = (3364 + 729 - 2500) / 3132

cos S = 0.5086.

∠S = [tex]cos^{-1}[/tex](0.5086)

∠S = 59.4°

Thus,

∠s angle value is  59.4°.

Answer:

Step-by-step explanation:

A dependent variable in an expression is one whose value can be determined only when the value of other variable (i.e independent) is known.

A. The cost at the fitness center depends on the number of months (x).

The cost is the dependent variable, and number of months (x) is the independent variable.

f(x) = 100 + 40x

Example, the cost paid for 12 months can be determined as;

f(12) = 100 + 40(12)

       = 100 + 480

       = 580

Thus, $580 would be paid for 12 months at the fitness center.

B. The lettuce is sold at $1.69 per pound. The cost depends on the number of pounds of lettuce bought.

The cost is the dependent variable, while the number of pounds of lettuce (x) bought is the independent variable.

So that;

f(x) = 1.69x

The cost of 10 pounds of lettuce can be determined as;

f(x) = 1.69(10)

     = 16.9

Thus, the cost of 10 lb of lettuce is $16.90.

Answer:

F(x)>0 over the interval [tex](-\infty,-4)[/tex]

Step-by-step explanation:

If you pay close attention to the intervals given in the options, you can see that they are talking about the region to the left of either x=-3 or x=-4. The only statements that makes sense is that:

F(x)>0 over the interval [tex](-\infty,-4)[/tex]

When they say F(x)>0, they mean that the graph is above the x-axis and that will only happen when the x-values that are to the left of x=-4, therefore the answer would be:

F(x)>0 over the interval [tex](-\infty,-4)[/tex]
