Answers

Answer:

28.3

Step-by-step explanation:

Answer:

28.3

Step-by-step explanation:

Use the Pythagorean theorem a^2 + b^2 = c^2

x is a, 17 is b, and 33 is c

x^2 + 17^2 = 33^2

Simplify:

x^2 + 289 = 1089

Subtract 289 from both sides:

x^2 = 800

Square root both sides:

x = √800

√800 is 28.28427, or 28.3

Answers

Answer:

<1 = 50

<2 = 40

<3 = 90

<4 = 90

<5 = 40

<6 = 50

<7 = 130

Step-by-step explanation:

<5 + <6 = 90

40 + <6 = 90

<6 = 50

<5 = <2 because of vertical angles

<2 = 40

<6 = <1 because of vertical angles

<1 = 50

<7 = <4 + <5

<7 = 90 + 40

<7 = 130

Answer:

Solution given:

<4=90°[vertically opposite angle]

<2=<5=40°[vertically opposite angle]

<3=90°[right angle]

again

<1+<2=90°[right angle]

<1=90°-40°=50°

<1=50°

again

<5=40°[given]

<6=<1=50°[vertically opposite angle]

<6=50°

again

<7=<4+<5=90°+40°=130°

The owner of a small restaurant bought 75 kilograms of rice. Each week, the restaurant uses 4.5 kilograms of rice.



Function `r` gives the remaining amount of rice, in kilograms, as a function of the number of weeks since the restaurant owner bought the rice.



Solve the equation `r(w)=30`and explain what the solution means in this situation.

Answers

Answer:

r(t) = 75 kg - (4.5 kg/wk)w

Step-by-step explanation:

Let r(t) represent the amount of rice remaining after w weeks.

Then:

r(t) = 75 kg - (4.5 kg/wk)w

please mark as brainliest

Answer:

w=10 and this means that 10 weeks after the rice was bought, 30 kilograms of rice remain.

Step-by-step explanation:

r(w)=75-4.5w is an equation for this function so I'll be using this. First insert r(w)= 30 into the equation.

75-4.5w=30

75-75-4.5w=30-75

-4.5w=-45

-4.5w/-4.5 = -45/ -4.5

w=10

Apologies if the explanation isn't thorough, I'll glady provide more details if necessary.

Find the value of x - this is circle segments.

Answers

Given:

Diagram of a circle and its two secant from an exterior point.

To find:

The value of x.

Solution:

We know that, If two secant are on a circle from an exterior point, then the products of measure of secants and measure of external segments of secants are equal.

Using the above property, we get

[tex](x+7)x=(2+2)2[/tex]

[tex]x^2+7x=(4)2[/tex]

[tex]x^2+7x=8[/tex]

[tex]x^2+7x-8=0[/tex]

Splitting the middle term, we get

[tex]x^2+8x-x-8=0[/tex]

[tex]x(x+8)-1(x+8)=0[/tex]

[tex](x+8)(x-1)=0[/tex]

Using zero product property, we get

[tex](x+8)=0[/tex] and [tex](x-1)=0[/tex]

[tex]x=-8[/tex] and [tex]x=1[/tex]

Side cannot be negative.

Therefore, the only possible value of x is 1.
