Step-by-step explanation:

1. 4 3/4=19/4

53/2=13/2

the total change of square will be. 19/4 + 13/2= 19+26/4=45/4

2. total change is 0.7+0.4=1.1

3.-7 1/6= -43/6

3 5/6= 23/6

-43/6 + 23/6 =-20/6 = -10/3

4. metals=2.625(m)

paper=5.58(p)

glass= x

total = 9.5(t)

m + p + x = t

2.625 + 5.58 + x =9.5

8.205 + x = 9.5

x = 9.5 - 8.205

x = 1.295

Hope That Helped

Christopher is analyzing a circle, y^2 + x^2 = 121, and a linear function g(x). Will they intersect?

Sav [38]

Circle: x^2+y^2=121=11^2 => circle with radius 11 and centred on origin.
g(x)=-2x+12 (from given table, find slope and y-intercept)
We can see from the graphics that g(x) will be almost tangent to the circle at (0,11), and that both intersection points will be at x>=11.
To show that this is the case,
substitute g(x) into the circle
x^2+(-2x+12)^2=121
x^2+4x^2-2*2*12x+144-121=0
5x^2-48x+23=0
Solve using the quadratic formula,
x=(48 &pm; √ (48^2-4*5*23) )/10
=0.5058 or 9.0942
So both solutions are real and both have positive x-values.

HEKP ASAP IM BEING TIMEDDDD!!!!!!

Aneli [31]

Answer:

subtract 2.4 from both sides, simplify to -3x=16.8, divide by -3, simplify to x=-5.6.

Step-by-step explanation:

-3x + 2.4 = 19.2

v -2.4 -2.4

v 0 16.8

-3x=16.8

-3 -3

x=-5.6

Quadrilateral QRST is inscribed in circle W as shown below. The measure of ∠QRS is 12 degrees less than three times the measure

Tju [1.3M]

Corrected Question

Quadrilateral QRST is inscribed in circle W as shown below. The measure of ∠QRS is 12 degrees less than three times the measure of ∠QTS and

mRQT=mRST .

(a)Determine the measure of Angle QTS .

(b)What is the common measure of angles RQT and RST ?

Answer:

(a)48 degrees

(b)90 degrees

Step-by-step explanation:

Theorem: Opposite angles of a cyclic quadrilateral are supplementary.

(a)

Let the measure of ∠QTS=x

Therefore: m∠QRS=3x-12

∠QTS and ∠QRS are opposite angles of a cyclic quadrilateral. By the theorem above:

x+3x-12=180

4x=180+12

4x=192

x=48 degrees

The measure of angle QTS is 48 degrees.

(b)Since mRQT=mRST

mRQT and mRST are opposite angles of a cyclic quadrilateral

Therefore:

mRQT+mRST=180 degrees

2mRQT=180

mRQT=90 degrees

Therefore, the common measure of RQT and RST is 90 degrees.

Devon made the scatter plot to track his bank balance over time.

Zepler [3.9K]

Using the line of best fit drawn on the graph, I can estimate from the graph that the possible bank balance is $160.
