Answer:

Equation of parabola: y = a(x-h)2 + k or x = a(y-k)2 +h, but the simple version is  y2 = 4ax.

Step-by-step explanation:

The probability of her NOT drawing a red card are very likely

Given that

In ∆ ABD , AB = BD------(1)

=> Angle B = Angle D

Since the angles opposite to equal sides are equal.

=> Angle A = Angle D

and

BC bisects Angle B

=> Angle BCA = Angle CDB ----(2)

And

BC = BC (Reflexive Property) -----(3)

From Eqⁿ(1),(2)&(3) we have

BA = BD

< ABC = BCD

BC = BC ( Common Side)

Therefore, ∆ ABC =~ ∆ DBC

by SAS property

Hence, proved.

The number of box is an illustration of proportions

8 boxes must be shown on the grid

The proportion is given as:

[tex]\mathbf{\frac{3}{8} = 18\ eggs}[/tex]

The above proportion means that:

3/8 of the total number of eggs is 18

Let the total number of eggs, be x

So, we have:

[tex]\mathbf{\frac{3}{8} \times x= 18\ eggs}[/tex]

Express 3/8 as a decimal

[tex]\mathbf{0.375 \times x= 18\ eggs}[/tex]

Divide both sides by 0.375

[tex]\mathbf{x= \frac{18}{0.375 }\ eggs}[/tex]

[tex]\mathbf{x= 48\ eggs}[/tex]

This means that, the total number of eggs is 48, and 8 boxes must be shown on the grid

Answer: 48oz = $1.68, 32oz = $0.80

Step-by-step explanation:

Let A be the price of the 48oz bottle and B the price for the 32oz bottle.

We are told that:

A = B + $0.88

------

The unit price is defined as the $ per oz.  

Let Au be the unit price for the 48oz size, and

Bu is the unit price for the 32oz size.

[This means that Au*(48) = A and Bu*(32) = B]

We are told that:

Bu + $0.01 = Au

=======

Find the cost of each.

A = B + $0.88

Au*(48) = Bu*(32) + $0.88

Substitute (Bu + $0.01) for Au

(Bu + $0.01)*(48) = Bu*(32) + $0.88

(48Bu + $0.48) = Bu*(32) + $0.88

16Bu + $0.48 =  $0.88

16Bu  =  $0.40

Bu = $0.025

The 32 oz bottle sells for $0.025/oz, or $0.80 a bottle

B = $0.80

Since A = B + $0.88

A =  $0.80 + $0.88

A = $1.68

The unit prices of 48-oz bottle and 32-oz bottle are $0.0183  and $0.01.

One type of operation in mathematics is division. We divide the phrases or numbers into the same number of components during this operation.

Given, 48-oz bottle is $0.88 more than the 32-oz bottle.

That means,

0.88 > 32 x ( 0.01)

0.88 > 0.32

And the unit price of the 32-oz bottle is $0.01 more than the unit price of the 48-oz bottle.

Unit price of 48-oz bottle,

= 0.88 / 48

= 0.0183

Unit price of the 48-oz bottle is $0.0183.

Therefore, $0.0183  and $0.01 are the unit prices of 48-oz bottle and 32-oz bottle.

Answer: (1,10)

Step-by-step explanation:

Assuming these are the correctly written equations:

-x + 5y = 49, and

x - 4y = -39

I'll rewrite them:

5y = x + 49

y = (1/5)x + (49/5)

-4y = -x -39

y = (1/4)x + (39/4)

=====

I'll assume the question is to find the point these two lines intersect (?).

See the attached graph.  They intersect at (1,10).

Answer:

a line through (-4,2) and (-8,-3) has slope = (2+3)/(-4+8) = 5/4 = (y-2)/(x+4)

cross multiply

5x +20 = 4y-8

5x -4y =-28

The difference between 12 and a number ➜ 12 - p

The sum of a number and 12 ➜ 12 + p

The quotient of a number and 12 ➜ [tex]\frac{p}{12}[/tex]

The expression in the box for the quotient of a number and 12, the sum of a number and 12 and the difference between 12 and a number are p/12 , 12 + p and p - 12.

Expression in mathematics is combination of variables with the use of operations and given rules. It can be in the form of equation, numbers etc.

If x and y are the arbitrary numbers.

And sum of the numbers are x + y,

difference of the numbers are x - y and

quotient of number x and y is x/y.

Here we have the expression and their representation,

the quotient of a number and 12 = p/12

the sum of a number and 12 = p + 12

the difference between 12 and a number =  p - 12.

Therefore the expression in the box for the quotient of a number and 12,

the sum of a number and 12 and the difference between 12 and a number are p/12 , 12 + p and p - 12.

Answer:

PX : XQ = 2 : 5

Step-by-step explanation:

Since RX is perpendicular to PQ , then

Δ RPX and Δ RQX are right triangle

Calculate PX and XQ using Pythagoras' identity in the right triangles

PX² = 20² - 16² = 400 - 256 = 144 ( take square root of both sides )

PX = [tex]\sqrt{144}[/tex] = 12

Similarly

XQ² = 34² - 16² = 1156 - 256 = 900 ( take square root of both sides )

XQ = [tex]\sqrt{900}[/tex] = 30

Then

PX : XQ = 12 : 30 = 2 : 5 ( in simplest form )

Answer:

AB is perpendicular to IB

A pair of segment that are marked perpendicular to each other are JC and CD.

As per the figure given,

∠JCD = 90°

In geometry, when it's stated that angle JCD is 90°, it means that angle JCD is a right angle. When two line segments or rays intersect to form a right angle, it indicates that they are perpendicular to each other.

In the context of the figure given, JC is a line segment , and CD is another line segment. The fact that angle JCD is a right angle (90°) tells that JC is perpendicular to CD.

Hence, as angle JCD is given as 90°, it establishes that JC is perpendicular to CD in the context of the figure given.
