Hi, I got 8 points off on this problem, can you help me figure out what I did wrong?

Answer:

Calculate the distance of AB, AC and BC. Then use the pythagorean theorem to see if AB^2 + AC^2 = BC^2

If it does, angle A is a right angle.

From the principles of geometry, we can see that the value of y is 3.

The lengths of the opposing sides in a rectangle are equal. A rectangle is a quadrilateral with four parallel opposed sides and four right angles (90-degree angles).

In specifically, a rectangle has two sets of equal-length opposite sides. In a rectangle, the lengths of the neighboring sides can vary, but the lengths of the opposing sides are always the same. This feature sets a rectangle apart from other quadrilaterals.

We know that;

10 = 2y + 4

10 - 4 = 2y

y = 6/2

y = 3

Multiplication equations can be modeled using decimal models.

The multiplication equation is: [tex]\mathbf{0.50 \times 0.90 = 0.45}[/tex]

From Phil model, we have the following highlights

So, the multiplication expression is:

[tex]\mathbf{\frac{50}{100} \times \frac{90}{100}}[/tex]

Express as decimals

[tex]\mathbf{0.50 \times 0.90}[/tex]

Multiply

[tex]\mathbf{0.50 \times 0.90 = 0.45}[/tex]

Hence, the multiplication equation is: [tex]\mathbf{0.50 \times 0.90 = 0.45}[/tex]

Answer:b equals T minus a minus c minus d all over 3 ⇒ 3rd answer

Step-by-step explanation:

- Tisha and her academic team have had three local matches

# Assume that the points of the local matches are a , c , d

- They will attend a district match

- District match points count for three times the number of points

 than local matches do

# Assume that the points of the district match is b

- T is the total points they will earned in the four matches

∵ The points in the local matches are a , c , d

∵ The point in district mach is 3b

∴ T = a + c + d + 3b

* Lets find b in terms of a , c , d , T

∵ T = a + c + d + 3b

- Subtract a from both sides

∴ T - a = c + d + 3b

- Subtract c from both sides

∴ T - a - c = d + 3b

- Subtract d from both sides

∴ T - a - c - d = 3b

- Divide both sides by 3

∴  

∴ b equals T minus a minus c minus d all over 3

Step-by-step explanation:

12.50

Answer:

is it 24 N?

as we know ....

force=mass * acceleration

force=4kg*6m/s2

hence force is 24N

The required Force = 24 N

The push or pull on an object with mass causes it to change its velocity.

Given that a body of 4 kg mass is accelerated at 6 m/s²

Force = ma

where m = mass and a = acceleration

F = 6*4 = 24 N

Hence, the Force required = 24 N

Step-by-step explanation:

The LCM of 4, 9, and 12 is the product of all prime numbers on the left, i.e. LCM(4, 9, 12) by division method = 2 × 2 × 3 × 3 = 36.

[tex]\frac{4}{9} -\frac{1}{12} = \frac{4.4}{9.4} - \frac{1.3}{12.3} = \frac{16}{36}- \frac{3}{36} = \frac{13}{36}[/tex]
