Answer:

yes.

traingle ABC is a right angled triangle because angle BÁC is a right angle.

Answer:

I believe it's Algebra because it contains variables and equations where you have to do what you just described in your question.

Hope I helped, have a nice day :)

Answer:

I believe it is A

Step-by-step explanation:

I dont quite remember the formula, but I belive that 30 would be correct because if im remembering correctly the formulas are "a + b = c" and "c - (a/b) = (a/b)

a/b = a or b, depending what they give you

Answer:

45°

Step-by-step explanation:

This is a isosceles triangle and also a right triangle, so it means it have an 90° ingernal angle and the other two internal angles have the same value. Remember that the sum of the internal angles of a triangle is always 180°, so:

180° -90° = 90°

90°/2 = 45°

Answer:

x° = 64°

Explaination:

This is a right angled triangle so one of the angle is 90°.

So, x° + 90° = 154° (Exterior angle property)

x° = 154° - 90° = 64°

Therefore x° = 64°

Answer: [tex]4\dfrac{1}{8}\ \text{bags}[/tex]

Step-by-step explanation:

Given

Jasper lawn is three-fourth of an acre

1 acre of land requires [tex]5\frac{1}{2}[/tex] bags

convert mixed numeral to fraction

[tex]\Rightarrow 5\dfrac{1}{2}=\dfrac{11}{2}[/tex]

[tex]\therefore 1\ \text{acre}\equiv\dfrac{11}{2}\ \text{bags}\\\\\Rightarrow \dfrac{3}{4}\ \text{acre}\equiv \dfrac{11}{2}\times \dfrac{3}{4}=\dfrac{33}{8}\ \text{bags}[/tex]

[tex]\Rightarrow \dfrac{33}{8}\ \text{bags}=4\dfrac{1}{8}\ \text{bags}[/tex]

Answer:

Actually,I don't understand the que but I will try.

Step-by-step explanation:

Supplementry it means the pair of angle that sum if 180° similarly, complimentry angle sum is 90°

Answer:

A: Complementary, Missing angle -29

E: Complementary, Missing angle -39

J: Complementary, Missing angle - 52

last one: Complementary, Missing angle -66

Answer:

Step-by-step explanation:

I'm assuming that you are solving for x, since there's nothing else you can do with this mathematically.

[tex]\frac{1}{2}x=-9[/tex] and the goal is to get the x all alone. So we have to lose the fraction. Do that by multiplying by the reciprocal of 1/2 which is 2/1 (a reciprocal is just a fraction flipped upside down). BUT...because this is an equation, what you do to the left side has to be done to the right side too. Like this:

[tex](\frac{2}{1})\frac{1}{2}x=\frac{-9}{1}(\frac{2}{1})[/tex]

On the left, everything cancels out but the x (which is why we do this), and on the right we multiply straight across the top and straight across the bottom to get

[tex]x=\frac{-18}{1}[/tex] which is

x = -18

Answer:

There are 4 negative integers between -5 and 2

Answer:

D. 7s

Step-by-step explanation:

h(t) = height off the ground

We know the height of the ball at the point when it hits the ground will be 0, so we set h(t) = 0:

h(t) = -16(t - 7)(t + 2) = 0

In order for this to be true, either:

"t - 7 = 0" or "t + 2 = 0"

We can solve these to get the times at which the ball will hit the ground, which gives:

t = 7 or t = -2

-2s is not a logical time because the ball can't hit the ground before it is thrown so this solution is not relevant;

7s therefore is the correct solution

Answer:

-21

Step-by-step explanation:

the formula is y=mx+b

m is the slope and b is the y-intercept

here, for the y value, there's -21 so the y-intercept is -21

Answer:

last option is correct

Step-by-step explanation:

use formula of reflection over x axis .

The coordinates of C , D , E are (-8 , -1) , (-6 , -5) , (-2 , -4) respectively.

formula :

(x , y) = (x  -y)

C(-8 , -1) = C'(-8 , 1)

D(-6 , -5) = D'(-6 , 5)

E(-2 , -4) = E'(-2 , 4)

Answer: Choice D (aka 4th option)

C ' (-8, 1)

D ' (-6, 5)

E ' (-2, 4)

===========================================================

Explanation:

The x axis reflection rule is [tex](x,y) \to (x,-y)[/tex]

x stays the same while y flips in sign (positive to negative, or vice versa).

All of this points to Choice D as the final answer.

Step-by-step explanation:

Step 1: Define

Identify

Point A(-5, 3)

Point B(1, 8)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Answer:

AB = 7.81

Step-by-step explanation:

Distance between 2 points = sqrt( (x2 - x1)^2 + (y2 - y1)^) )

x2 = - 5

x1 = 1

y2 = 3

y1 = 8

D = sqrt( -5 - 1)^2 + (3 - 8)^2 )

D = sqrt( (-6)^2 + (-5)^2 )

D = sqrt( (36 + 25)

D = sqrt( 61)

D = 7.81
