Answer 1

Answer:

The sum of the interior angles of any triangle are equal to 180

therefore in this triangle, m<a+m<c+m<b=180

we know that 9x-26 and m<a are supplementary angles (meaning they add to 180) and therefore,

9x-26+a=180

9x+a=206

a=206-9x

(206-9x)+(2x-12)+(4x+43)=180

combine like terms

-3x+237=180

-3x=-57

x=19

if x=19 then we can substitue it in for c

4x+43=c

4(19)+43=c

c=119

A line, L, has the equation y = 5x – 1.
Write down the gradient of line L.

Answers

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope (gradient) and c the y- intercept )

y = 5x - 1 ← is in slope- intercept form

with gradient = 5

david earns $1.50 per hour more than peter. together, they earn $940 if they both work 40 hours in a week. how much money per hour do david and peter earn?

Answers

Answer:

469.25

Step-by-step explanation:

peter=x

david=x+1.50

x+(x+1.50)=940

x=940-x-1.50

2x=940-1.50

2x=938.5

x=938.5/2

x=469.25

B. 4

Step-by-step explanation:

Slope = (-2-6)/1-3) = = - 8/ - 2 = 4

Answer:

C. 4

Step-by-step explanation:

slope = (y2 - y1)/(x2 - x1)

slope = (-2 - 6)/(1 - 3)

slope = -8/(-2

slope = 4

You are buying ribbon to make costumes for a school play. Organza ribbon costs $.07 per yard. Satin ribbon costs $.04 per yard. Write an equation to model the possible combinations of yards of organza ribbon and yards of satin ribbon you can buy for $5. List several possible combinations.

Answers

Answer:

Let's define the variables:

x = yards of Organza ribbon that you buy.

y = yards of Satin ribbon that you buy.

We know that the price per yard of Organza ribbon is $0.07, this means tat if you buy x yards, the cost will be:

C = x*$0.07

And the cost of the Satin ribbon is $0.04, so if you buy y yards of that ribbon, the cost will be:

C = y*$0.04

Adding that together, the total cost is:

C = x*$0.07 + y*$0.04

Now we know that you pay $5, this means that the total cost is exactly $5, then we have the equation:

$5 = x*$0.07 + y*$0.04

Now we can isolate the variable y to get:

y = ($5/$0.04) - x*($0.07/$0.04)

y = 125 - x*1.75

Now we can just input different values of x to find the correspondent value of y.

This means that:

if x = 0 (0 yards of the Organza ribbon)

then:

y = 125 - 0*1.75 = 0

This combination is:

0 yards of organza, and 125 yards of satin.

Now, if x = 20, then:

y = 125 - 20*1.75 = 90

This combination is:

20 yards of organza, and 90 yards of satin.

if x = 40, then:

y = 125 - 40*1.75 = 55

This combination is:

40 yards of organza, and 55 yards of satin.

The 3 combinations that we found cost exactly $5.

y - 7 = 21 Your answer should be the value for the variable y.

Step-by-step explanation:

The ratio 10:7 represents the number of pink markers to the number of orange markers.

What is the ratio?

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

Total number of pink Mrs. Andrews has = 10

Total number of orange Mrs. Andrews has = 7

The ratio of number of pink markers to the number of orange markers:

= 10:7

Thus, the ratio 10:7 represents the number of pink markers to the number of orange markers.

Diagram shows the composite solid formed by a cuboid and a right prism. Trapezium LMNP is the uniform cross section of the prism. It is given the volume of the composite solid is 444cm³. Calculate the length, in cm of MN

Answers

Answer:

MN = 7 cm

Step-by-step explanation:

Well the volume we can separate into pieces

first the ABCDEFGH (? you know this cuboid)

which has a volume of

[tex]V = AB\cdot BC\cdot CH\\\\V = 3*6*(3+JY+4)[/tex]

if you ask where does the 4 come from

it comes from LP = KB = YC and JY + YC =JC

[tex]V = 18(7+MX)[/tex]

this is because JY = MX

the other volume is of BCNPKLXY (hope you understand which one)

and the volume is

[tex]V = BP*PN*NX\\\\V=8*6*4\\\\V = 192[/tex]

and the last one is KYXLMJ (the top "triangle")

the volume is

[tex]V = \frac{LX*XM}{2}*LK\\\\V = \frac{6*MX}{2}*8\\\\V= 6*4*MX\\\\V=24MX[/tex]

so now add them up

and has to equal 444

[tex]V_T = 18(7+MX)+192+24MX\\\\V_T = 126+18MX+192+24MX\\\\V_T = 318+42MX\\\\444=318+42MX\\\\444-318=42MX\\\\126=42MX\\\\MX = 3[/tex]

and finally we know that MN = MX + XN = 3+4 = 7

so here is our answer MN = 7 cm

a couple of notes

[tex]1.\:\angle LXM = 90\\\\2.\:\angle KYX = 90[/tex]

3. the units don't matter due to the fact that everything is in cm

4. see the picture below to get a better idea of which prism I am talking of
