1 answer:

7 0

One pattern is 22, 18, 14, 10, 6, 2 hope this helps just keep subtracting 4. You can go from the highest number to the lowest. Thanks for asking!

Meredith solved a quadratic equation. Her work is shown below.

Damm [24]

Answer:

Step 2

Step-by-step explanation:

Meredith made a fatal mistake or error in step 2;

Any quadratic problem will always have two solutions. Therefore since, we only have one solution here, it is wrong. The mistake was incurred in step 2;

From the given problem ;

<u> Wrong right</u>

2(x + 4)² = 242

(x + 4)² = 121 Step 1

x+4=11 Step 2 x + 4 = ± 11

x = 7 Step 3 x + 4 = 11 or x + 4 = -11

x = 11- 4 or x = -11 - 4

x = 7 or -15

Im not sure how to find the missing angle

LuckyWell [14K]

Answer:

Step-by-step explanation:

the question is asking for the length of the side labeled x

use Pythagoras' theorem to find that side

where c = x because c represents the hypotenuse in the theorem and x is on the hypotenuse in this problem

c = $\sqrt{a^{2} + b^{2} }$

sooo plug in a = 14 and b = 10

c = $\sqrt{14^{2} + 10^{2} }$

c = $\sqrt{196+100}$

c = $\sqrt{296}$

c= 17.20465..... ( that's the approx. length of side x in the problem )

since this is a right triangle we could use trigonometry to find the two angles use SOH CAH TOA to remember how those functions fit on the triangle.

Sin(Ф)=Opp/Hyp Cos(Ф)=Adj/Hyp Tan(Ф)=Opp/Adj

since we know the Hyp (hypotenuse) and the side adjacent will be the side with the 10 soooo...

Cos(Ф)=10/17.20465

Ф = arcCos(10/17.20465)

Ф = 54.4623° is the angle on the side with 10

the side with 14 then has an angle of 35.5376°

saul makes green paint by mixing blue paint. For every 4 gallons of green paint he uses 3 gallons of blue paint .Drag the correc

Aleksandr [31]

Green paint is made by mixing yellow and blue paint. Given that, every 4 gallons of green paint contains 3 gallons of blue paint, how many gallons of yellow paint is in 4 gallons of green paint? Green-blue=yellow
4-3=1 Therefore 1 gallon of yellow paint is in 4 gallons of paint.
The ratio of blue to yellow is 3:1
If there are 16 gallons of green paint, how many gallons blue and yellow are in it? blue= 3 in 4 green
If 16=4
=3
3/4*16=12 Therefore there are 12 gallons of blue paint in 16 gallons of green paint.
Yellow=1 in 4 gallons
If16=4
=1
1/4*16=4 Therefore there are 4 gallons of yellow paint in 16 gallons of green paint.
I am not so sure about this but I hope it helps.Sorry if it doesn't
