Answer:

The mass of the piece of granite with volume of 75 cm^3 is 202.5 grams.

Step-by-step explanation:

Let

m = the mass of a piece of granite whose volume is: 40 + 35 = 75 cm^3 (greater by 35 cm^3)

Since Density = Mass / Volume and we are talking about pieces of the same material (same density) we can write:

m/75 = 108/40

m = 202.5 g

Given:

A figure of a quadrilateral.

To find:

The measures of angle 1 and angle 2.

Solution:

The given figure has two pairs of congruent adjacent sides. So, the quadrilateral in the figure is a kite.

We know that the diagonals of a kit are perpendicular to each other at the point of intersection.

[tex]m\angle 1=90^\circ[/tex]

According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.

[tex]90^\circ+65^\circ+m\angle 2=180^\circ[/tex]

[tex]155^\circ+m\angle 2=180^\circ[/tex]

[tex]m\angle 2=180^\circ-155^\circ[/tex]

[tex]m\angle 2=25^\circ[/tex]

Therefore, the correct option is C.

Answer:

They will both blink again at 3:12 pm.

Step-by-step explanation:

As indicated by the question, the way to solve is to find the Lowest (or Least) Common Multiple of both numbers.

As such:

[tex]\text{List the factors of 12 and 44:}\\12=2*2*3\\44=2*2*11\\\\\text{Take the common factors only once and multiply them by the non-common factors:}\\2*2*3*11=132 \text{ (LCM)}[/tex]

Now knowing the LCM is 132, we convert those minutes into hours and minutes:

[tex]\frac{132}{60}=2\frac{12}{60} \text{ (2 hours and 12 minutes)}[/tex]

Add this to the original time:

[tex]1:00\text{ pm } + \text{ }2:12 \text{ }= \text{ }3:12\text{ pm}[/tex]

Answer:

[tex]y=\frac{1}{3}x +5[/tex]

Step-by-step explanation:

Linear equations are typically formatted in slope-intercept form:

[tex]y=mx+b[/tex] where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope (m)

Parallel lines will always have the same slope. Therefore, this line will also have a slope of [tex]\frac{1}{3}[/tex]. Plug this into our equation:

[tex]y=\frac{1}{3} x+b[/tex]

2) Determine the y-intercept (b)

To solve for the y-intercept (b), plug the given point (-3,4) into our equation and isolate b.

[tex]4=\frac{1}{3}(-3)+b\\4=\frac{-3}{3}+b\\4=-1+b[/tex]

Add 1 to both sides

[tex]4+1=-1+b+1\\5=b[/tex]

Therefore, the y-intercept is 5. Plug this back into our original equation with the slope:

[tex]y=\frac{1}{3}x +5[/tex]

I hope this helps!

Answer: 42.53

Step-by-step explanation:

iok so because we are give the two sides 19 and 14 from here we need to determine what they are concidered. 19 is on the hypotenuse, and 14 is on the adjacent. from this, we can use Soh cah toa, we are looking for h and a which gives us cah which is cosine, now we imput this into our calculator

Cos-1(14/19) this should then give you 42.53 :) hope this helps

Answer:

[tex] \huge \boxed{ \red{ \boxed{\begin{cases} \theta = {45}^{ \circ} \\ \theta= {60}^{ \circ} \end{cases} }}}[/tex]

Step-by-step explanation:

distribute tan(θ):

=>tan²(θ)-(tan(θ)+√3tan(θ))+√3=0

remove parentheses:

=>tan²(θ)-tan(θ)-√3tan(θ)+√3=0

so this equation is now in standard form i.e ax²+bx+c=0

we can solve by factoring as we solve quadratic equation

factor out tanθ:

=>tan(θ)(tan(θ)-1)-√3tan(θ)+√3=0

factor out -√3:

=>tan(θ)(tan(θ)-1)-√3(tan(θ)-1)=0

group:

=>(tan(θ)-√3)(tan(θ)-1)=0

separate it as two different equation:

[tex] \implies \begin{cases} \tan( \theta) - 1 = 0 \\ \tan( \theta) - \sqrt{3} = 0 \end{cases}[/tex]

add 1 and √3 to both sides to first and second equation respectively:

[tex] \implies \begin{cases} \tan( \theta) - 1 + 1 = 0 + 1 \\ \tan( \theta) - \sqrt{3} + \sqrt{3} = 0 + \sqrt{3} \end{cases} [/tex]

[tex] \implies \begin{cases} \tan( \theta) = 1 \\ \tan( \theta) = \sqrt{3} \end{cases} [/tex]

[tex] \therefore \begin{cases} \theta = {45}^{ \circ} \\ \theta= {60}^{ \circ} \end{cases} [/tex]

Answer: 1) 8x + 2 = 90 1a. 11 2. 13x-10= 133 2a. 11

Both solve for 11.

Step-by-step explanation: 1) they’re both the same measure so they equal each other

Subtract 2 from each side 8x = 88 and x is 11

13x - 10 = 133 they’re both the same measures so they equal each other.

Add 10 to both sides because it’s already negative and 13x = 143 and you get 11

Answer:

11 for both

Step-by-step explanation:

Mode refers to a value that appears most frequently in a data set.

For example the mode in the data set below is 3 :

1, 2,3 4,3,3,9,10

3 is the mode because it appears 3 times in the data set while the other values appear only once.

Mode is a measure of central tendency

Other measures of central tendency includes : mean and median

Relative frequency measures how often a value appears relative to the sum of the total values. The relative frequency with the highest relative frequency value occurs the most

Blue has the highest relative frequency value

Answer:

Step-by-step explanation:

9y-4 = 50

9y = 54

y= 6

9y-4+7x+xy = 180

9(6)-4+7x+6x= 180

54-4+13x = 180

13x+50 = 180

13x = 130

x = 10

Answer:

b(y-intercept)=(0,1) and M(slope)=-2

Step-by-step explanation:

use the slop formula and the slope intercept form to find the slope and y intercept. slope -2. y-intercept (0,1)

with that information, the equation would be y=mx+b. y=-2x+(0,1)

Step-by-step explanation:

Answer:

x is 103 cause it is opposite angles and y is 77 180-103 hope this helps you

Answer: x=103° y=77°

Step-by-step explanation:

Opposite angles are always the same so, as x is opposite to 103°, it would be 103° too.

To work out what y is you would have to do 180-103=77°. The reason why is because angles on a straight line always add up to 180° and you can see that 103° and y are on the same line.

Hope this helps :)
