Answer:

60??

Step-by-step explanation:

so the measure of a full circle is 360, so if its a half circle it is 180, and its divided into 3 sections( the porblem is if there not even sections this is wrong, i cant tell if they are or not) so you do 180 divided by 3 and your answer is 60. if there are uneven sections all you have to do it take your protractor and line up the stright line with the bottom line then see what small number is the line pointing too. Sorry if this dosent make sense i can try to clarifi if you dont get it.

Answer:

Step-by-step explanation:

the sum of the angles is 360 degrees

you have 3 angles equal to 91

91*3=273

87/3=29

the angle g, or d, is 29

Rewrite the following equation in standard form and determine if there is a solution.

Debora [2.8K]

Answer:

| x + 4 | = -1 No solution

Step-by-step explanation:

3 | x + 4 | + 12 = 9

Subtract 12 from both sides: 3 | x + 4 | = -3

Divide both sides by 3: | x + 4 | = -1

Absolute value cannot be negative, so there is no solution.

Given the function f(x) = 5x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3.

Debora [2.8K]

$f(x)=5x\\\frac{f(1)-f(0)}{1-0}\\\frac{5-0}{1}\\5\\\\\frac{f(3)-f(2)}{3-2}\\\frac{15-10}{1}\\5$

A: 5; 5

B: 1; they are the same

Please answer !!!!!!!!!! Will mark brainliest !!!!!!!!!!!!!

Answer & Step-by-step explanation:

$\frac{1}{4}(x+5)^2-1=3$

Add 1 to both sides.

$\frac{1}{4}(x+5)^2=4$

Multiply both sides by 4.

$(x+5)^2=16$

Take the square root of both sides.

$\sqrt{(x+5)^2} =\sqrt{16}$

$x+5=4$

Subtract 5 from both sides.

$x=-1$

Answer:

t = 5 seconds h = 128 feet

Step-by-step explanation:

The given equation of the object is :

$h(t)=-16t^2+64t+80$ .....1

When it hits the ground,

h(t) = 0

So,

$-16t^2+64t+80=0\\\\t=-1\ s\ and\ t=5\ s$

The object will hit the ground in 5 seconds.

Now, put t = 1 s in equation (1).

$h(1)=-16(1)^2+64(1)+80\\\\h(t)=128\ ft$

The object is at a height of 128 ft at 1 second.
