Help me classify the triangles by its sides and measuring its angles :) ​

Answer:

a)4/3

b)9/20 or 0.45

c)96

Step-by-step explanation:

a) j=3

72=20j+9p

72=20(3)+9p

72=60+9p

-9p=60-72

-9p=-12

p=-12/-9

p=4/3

b) m =1/2

20k-5=8m

20k-5=8(1/2)

20k-5=4

20k=4+5

20k=9

k=9/20 or 0.45

c) k=18

p+1/3k-20=82

p+1/3(18)-20=82

p+6-20=82

p=82+20-6

p=96

idk if this is right but I tried my best heh-

Answer:

cost of each bottle of juice is $0.77

Step-by-step explanation:

Let the cost of 1 bottle be $x

multiplying both side by 3

then cost of 3 bottle will be 3*$x = $3x

given that

total cost of 3 bottles =  $2.31

thus

3x = 2.31

dividing both side by 3

x = 2.31/3 = 0.77

Thus, cost of each bottle of juice is $0.77

Answer:

$0.77 for each bottle of juice

Step-by-step explanation:

Madelyn buys 3 bottles of orange juice at the corner store for a total cost of $2.31.

So,

2.31/3 = 0.77

Thus, $0.77 for each bottle of juice

Step-by-step explanation:

Answer:

the height of the larger container is 6 cm

Step-by-step explanation:

The computation of the height of the large container is shown below:

In the case when the factor of linear scale for two solid be k

So the factor of volume scale be k^3

Now the volume scale factor is

= 128 ÷ 54

= 64 ÷ 27

= (4 ÷ 3)^3

Now the height of the large container is

= 4.5 cm × 4 ÷ 3

= 6 cm

hence, the height of the larger container is 6 cm

Answer:

solution is (-2, 2) so x-coordinate of solution is -2

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

First, we have to write down both equations.

y = x + 4

3y = -2x + 2

Now we already have an equation that we can plug into the other equation.

= 3(x + 4) = -2x + 2

= 3x + 12 = -2x + 2

= 5x + 12 = 2

= 5x = -10

x = -2

Now we know that x = -2, and the question asks for the x-coordinate, which is -2.

Answer:

x < 6

Step-by-step explanation:

1. 3x+2x = 5x

2. 5x - 8 < 22

3. 22+ 8 =30

4. 5x < 30

5. 30/5 = 6

6. x < 6

Step-by-step explanation:

3x-8<-2x+22

3x+2x< 22+8

5x<30

Divide both sides by 5

x=30

Answer: the correct answer is a.

Step-by-step explanation:

Answer:

In the last two overs, the bowler gave 14 runs.

Step-by-step explanation:

The bowling rate of 4.5 in the first 8 over means he gave 32.5 runs.

i.e.

Score given in first 8 overs = 4.5 × 8 = 36

Given that the bowling economy 5 at the end of 10 overs means the bowler must have given 10 × 5 = 50 score in the total 10 overs.

so, subtract 36 from 50 to get the score he will be giving in the last two overs.

i.e. score given the last two overs = 50 - 36 = 14

Therefore, in the last two overs, the bowler gave 14 runs.

Answer:

$284.99 should go to Mr. Aceves’ class, $174.41 should go to Mrs. Baca’s class, and $140.60 should go to Mr. Canyon’s class.

Step-by-step explanation:

Firstly, to calculate the portions each class should have, we should find the proportion each class takes up.

Hence, let's say A represents Mr. Aceves' class, B represents Mrs. Baca's class, and C represents Mr. Canyon's class.

The total number of box tops collected would be 3760 + 2301 + 1855 = 7916 box tops.

Therefore, the total proportions would be:

A = [tex]\frac{3760}{7916}[/tex]

B = [tex]\frac{2301}{7916}[/tex]

C = [tex]\frac{1855}{7916}[/tex]

Hence, we can finally multiply these proportions with the total prize to find the appropriate division:

Mr. Aceves' class gets [tex]\frac{3760}{7916} \cdot 600 \approx 284.99[/tex].

Mrs. Baca's class gets [tex]\frac{2301}{7916} \cdot 600 \approx 174.41[/tex].

And Mr. Canyon's class gets [tex]\frac{1855}{7916} \cdot 600 \approx 140.60[/tex].

Finally, $284.99 should go to Mr. Aceves’ class, $174.41 should go to Mrs. Baca’s class, and $140.60 should go to Mr. Canyon’s class.

Hope this helped!

Answer:

yes, that's correct!

Step-by-step explanation:

Answer:

The equation is;

2y = 3x + 6

Step-by-step explanation:

We start by calculating the slope of the line

m= y2-y1/x2-x1

m = (6+3)/(2+ 4) = 9/6 = 3/2

The point slope form would be;

y-y1 = m(x-x1)

Let us use the point (-4,-3)

Thus, we have

y + 3 = 3/2(x+ 4)

2y + 6 = 3x + 12

2y = 3x + 12-6

2y = 3x + 6

Answer:

12²

Step-by-step explanation:

12 is the base

2 is the exponent

12 squared or 12 times 12 equals 144

Answer:

144 can be divided by 12

so 12 *12 =144

therefore 144 can be written as [tex]12^{2}[/tex]

Step-by-step explanation:

Given :

Jessica needs 233 feet of wood to build a fence the word comes in length of 11 feet.[tex]N= 21\times 2[/tex]

To Find :

How many pieces of wood should Jessica by Samuel needs twice as many feet as Jessica how many pieces of wood does Samuel need.

Solution :

Total number of pieces of wood Jessica needs is :

[tex]n = \dfrac{233}{11}\\\\n = 21.18[/tex]

Since number of pieces cannot be negative.

So, n = 21

It is given that Samuel needs twice as many feet as Jessica need.

So,

N = 21 × 2 = 42

Therefore, Samuel needs 42 pieces of wood.

Answer:

x=-5

Step-by-step explanation:

22=-2x+4(-4x-17)

We move all terms to the left:

22-(-2x+4(-4x-17))=0

 We calculate terms in parentheses: -(-2x+4(-4x-17)), so:

-2x+4(-4x-17)

We multiply parentheses

-2x-16x-68

We add all the numbers together, and all the variables

-18x-68

Back to the equation:

-(-18x-68)

We get rid of parentheses

18x+68+22=0

We add all the numbers together, and all the variables

18x+90=0

We move all terms containing x to the left, all other terms to the right

18x=-90

x=-90/18

x=-5

Answer:

Step-by-step explanation:

22 = -2x + 4(-4x - 17)

22 = -2x + 4*(-4x) - 4*17

22 = -2x - 16x  - 68     {Combine like terms}

22 =  -18x - 68            {Add 68 to both sides}

22 + 68 = -18x

90 = -18x           {Divide both sides by (-18)

90/-18 = x

x = -5
