Answer:

OK as bd is parallel go xy

x and 76 becomes co interior angles that Is sum is 180

x + 76 = 180

x = 180- 76 = 104 option b is ri8

congrats now ur done :)

How do i graph this? plz help

lesantik [10]

Step-by-step explanation:

So this is Slope intercept form. Or y = mx+b

M is the slope, b is the y intercept.

Now. We have 5/3 as the slope, or y/x, and -9 and the y intercept.

Start from the point (0,-9) (y intercept)

Go up 5 (In 5/3)

Go to the right 3 (in 5/3)

And graph where that lands.

Using the word HIPPOPOTAMUS, match the items in the left column to the items in the right column

avanturin [10]

Answer:

(see below)

Step-by-step explanation:

Ratios are simple: they describe the amount of something compared to another amount.

Ratios are [number] : [number]. Use this format for your answers:

For 1, finding the ratio of P's to O's means to count P's, then O's.

HIPPOPOTAMUS

There are 3 P's and 2 O's, so 3:2.

For 2—ratio of O's to the other letters, do the same thing:

HIPPOPOTAMUS

There are 2 O's and 12 total letters, so 2:12. However, we can simplify that to 1:6.

For 3, the ratio of letters to P's:

There are 3 P's and 12 total letters, so 12:3. We can simplify it to 4:1.

For 4, the ratio of vowels to consonants:

The vowels are a, e, i, o, u. The consonants are all the other ones.

So, in:

HIPPOPOTAMUS

There are 5 vowels and 7 consonants, so 5:7.

For 5, the ratio of total letters to consonants,

there are 12 total letters and 7 consonants, so 12:7.

What is the quotient: (72y3 + 12y2 – 30y) ÷ 6y ? need help dividing.

Misha Larkins [42]

Answer:

$12y^{2}+2y-5$

Step-by-step explanation:

we know that

$(72y^{3}+12y^{2}-30y)/6y=(\frac{72y^{3}}{6y})+( \frac{12y^{2}}{6y})-(\frac{30y}{6y} )$

Simplify

$12y^{2}+2y-5$

A beverage company works out a demand function for its sale of soda and finds it to be x = D(p) = 3100 - 20p where x = the quant

Shtirlitz [24]

Answer with Step-by-step explanation:

We are given that a demand function

$x=D(p)=3100-20p$

Where x=The quantity of sodas sold

p=Per can price (in cents)

We have to find the price p for which the demand inelastic.

Differentiate the demand function w.r.t p

$D'(P)=-20$

Price elasticity of demand= $E(p)=\frac{-pD'(p)}{D(p)}$

Price elasticity of demand= $E(p)=\frac{-p(-20)}{3100-20p}$

When demand is inelastic then

E(p)<1

$\frac{20p}{3100-20p}$ <1

Multiply by (3100-20p) on both sides

$20p$

Adding 20p on both side of inequality

$40p$

Divide by 40 on both sides

$p$

When the value of price is less than 77.5 then the demand of elasticity is inelastic.

In the figure below, what value of x makes G the incenter of JKL?

Contact [7]

Answer:

x=8.

Step-by-step explanation:

For triangle GTL

h²=p²+b²

or, 13²=p²+12²

or, 169=p²+144

or, p²= 25

or, p=5

so, GT = 5

now

for triangles GTL and GTJ

<GTL=<GTJ(both are 90° because GT is perpendicular to JL)

<JGT=<LGT=90° (GT is perpendicular to JL so it bisects G)

GT=GT(common)

triangles GTL and GTJ is congruent by A.S.A axiom

JT=12(correspong side of congruent ttriangle are equal)

now

JG= 13(corresponding side of congruent triangles are equal)

now

for triangle JGT, it is a right angled triangle as <JGT = 90°)

Let <JGT be G.

tanG=p/b

or, tanG=12/5

G= 67.4°

<JGT=67.4°

now

<JGR=<JGT=67.4°(JG is at midpoint bisecting <RGT)

in JGR,

<JRG=90°(RG is perpendicular to JK as <GRK is 90°)

now

JGR is a right angled triangle so

cosG=b/h

or, cos67.4=(x-3)/13

or, cos67.4(13)=x-3

or, 4.99=x-3

or, 5 = x-3

so, x = 5+3

so, x = 8
