Find the value of: (i) [(4 -1 - 5 -1 ) -1 ] ÷ [ (5 2 ) 3 x 5 -5 ]

Answer:

Step-by-step explanation:

Area of ∆ = 1/2 * base* height

b= 12 m

h= 18.2 m

Area = 1/2*12*18.2

Considering,

base= 21.8 m

A= 1/2*21.8* h

[tex] \frac{1}{2} \times 12 \times 18.2 = \frac{1}{2} \times 21.8 \times h[/tex]

[tex]h = \frac{12 \times 18.2}{21.8} [/tex]

[tex]h = 10.018 \: m[/tex]

Answer:  16 one side 32 second side 48 third side

Step-by-step explanation:

16;32;48

3;4;5

Answer:

24, 32, 40

Step-by-step explanation:

We know that the ratio of the sides is 3:4:5, and that total is 96.

First I tested out some numbers by multiplying them by 3, 4, and 5

Eventually I got to 8;

8×3:8×4:8×5 --> 24:32:40 --> 3:4:5

24+32+40=96

Meaning, the sides were 24, 32, and 40

Hope this helps, and good luck!

Explanation:

AC = XZ shows that the horizontal pieces are congruent. This is the "S" of "ASA" as it stands for the pair of congruent sides. We are also given angle A = angle X. This is one of the "A"s in "ASA" as it stands for pair of congruent angles.

What we're missing is the other pair of angles. We must pick C and Z because they help sandwich the two sides mentioned above. ASA has the two angles surrounding the sides; or the sides are between the angles. We can't pick B and Y, unless we were doing AAS which is a similar related idea. The order matters when it comes to ASA and AAS. However, AAS is the same as SAA.

Answer:

AC=XZ

so the correct answer is D

Answer:

Check Explanation

Step-by-step explanation:

The amygdala is the brain's emotional center. It is responsible for instinctual thinking and impulse control. It develops during early teenage years and this means the amygdala is not developed to the optimal level during teenage years. This makes teenagers very prone to impulsive behavior.

Also, the prefrontal cortex which is responsible for decision-making skills and the ability to measure risks is not fully developed in the teenage child stage. This is why teenagers make poor decisions and aren't great at measuring risks thereby making riskier choices like using the phone while driving.

These two brain components are fully developed in adults hence, it is less likely for adults to make poor decisions like texting while driving, which is a riskier thing to do than not using a seatbelt.

Again, teenagers have this invincibility feeling where they feel like they are more active and can react faster to road dangers. This deceives them into making such riskier decisions.

The current world also has turned into something else where people (teenagers especially) strive to get the most current news information as they are happening. The need to stay connected to social media is another reason why teenagers can't stay off their phones.

Finally, the fact that public intervention programs and ad campaigns promoting seat-belt use way more than not using cell-phones use while driving also mean more people are more conscious about using seatbelts while driving than not using their cellphones. In recent times, the campaigns, laws and bans on use of phones while driving are just gaining prominence.

In conclusion, the combination of all these factors/reasons is why the percentage of teenage high school students who use phones while driving is way more than the percentage that don't use a seatbelt although texting while driving is arguably much riskier than not wearing a seat belt.

Answer:

4.5 < T < 5.5

Step-by-step explanation:

Nearest 5 minutes could be 4.5 to 5.49

The computation of the limits in between is shown below:

Now Multiply these numbers by 30

4.5 × 30 = 135

5.4 × 30 = 162

5.5 × 30 = 165

We can easily round 5.5 would to 6, since we cannot use 5.5.  

Therefore  

135 < T < 162

Therefore If the correct answer is  135 < T < 165

So it must be 4.5 < T < 5.5

Answer:

(C) 7.5 units.

Step-by-step explanation:

If an empty can weighs 3 units each, there are 12 cans. The cans by themselves would weigh 3 * 12 = 36 units. Since the total weights of the syrup in cans is 492 units, the 5 liters of syrup (without the cans) would weigh about 492 - 36 = 456 units.

12 of 5 liters of syrup, we can say there are 12 * 5 = 60 liters of syrup. So, to find the weight of 1 liter of syrup, we just need to do 456 / 60 = 7.6. That is approximately 7.5 units.

So, the weight of 1 liter of syrup alone (without a can) is most nearly (C) 7.5 units.

Answer: 28.5 square units

Step-by-step explanation: Count the whole squares in the figure then figure the areas of the triangular areas around the sides. Whole squares 3+5+5+5 = 18

Left side: 5/2 = 2.5

Top (2)( 3/2) = 3

Right: 4/2= 2

Bottom 6/2 = 3

Sum of triangular areas: 10.5

Add squares and triangles:

18+10.5= 28.5

It may be possible to compute the area by using the Pythagorean Theorem to get the lengths of the bases and height, but that's a bit more complicated!

Answer:

The equation is [tex]y=\frac{-3}{2} x-9[/tex]

Step-by-step explanation:

First, you will have to find the slope of the two points.To do that, you will have to use the formula : [tex]m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

Our points are [tex](1,6)[/tex] and [tex](5,0)[/tex]

We will have to substitute the points into the formula.

[tex]m=\frac{0-6}{5-1}[/tex]

Then, we will simplify

[tex]m= \frac{-6}{4}[/tex]

We could simplify that fraction into [tex]\frac{-3}{2}[/tex]

So, our slope is [tex]\frac{-3}{2}[/tex]

We will have to pick a coordinate point, and choose. I chose [tex](1,6)[/tex]

We will substitute the x-value and the y-value of the coordinate point, including our slope, to calculate the y-intercept.

The formula we will be using is [tex]y=mx+b[/tex]

We will substitute in our values which will make it look like:

[tex]6=\frac{-3}{2} (1)+b[/tex]

We will then multiply [tex]\frac{-3}{2}[/tex] by [tex]1[/tex] which will stay the same.

Then, we will multiply [tex]\frac{-3}{2}[/tex] by [tex]6[/tex] which will equal [tex]-9[/tex]

[tex]-9=b[/tex]

Hence, the equation for our line is [tex]y=\frac{-3}{2} x-9[/tex]

Answer:

Therefore, the correct option is;

T(-2, 4) ry-axis

Step-by-step explanation:

Given that the points of the triangle MNO are N(3, -2), O(1, -3), and M(5, -4), while M''(-3, 0), N''(-1, 2), and O''(1, 1), we have;

N(3, -2) → N''(-1, 2)

For reflection about the y-axis, the y values are the same and the x values change sign

If we translate by (-2, 4) we have;

N(3, -2) → N'(3 - 2, -2 + 4) = N'(1, 2)

If we now reflect about the y-axis, we have;

N'(1, 2), reflection → N''(-1, 2) which is correct

For O(1, -3), O''(1, 1), we have;

O(1, -3) → O'(1 - 2, -3 + 4) = O'(-1, 1)

Reflecting about the y-axis gives;

O'(-1, 1) → O''(1, 1) correct

For M(5, -4) M''(-3, 0)

M(5, -4) → M'(5 - 2, -4 + 4) = M'(3, 0)

M'(3, 0) → M''(-3, 0)

Therefore, the correct option is T(-2, 4) ry-axis.

Answer:

A. [tex]Change = Final\ temperature - Inicial\ temperature[/tex]

B. Negative change of 18 degrees

C. Negative change of 23 degrees, final temperature would be -8°F

Step-by-step explanation:

A.

The expression that represents the change in temperature is:

[tex]Change = Final\ temperature - Inicial\ temperature[/tex]

B.

If the final temperature is -3°F and the inicial temperature is 15°F, the change in temperature is:

[tex]Change = -3 - 15 = -18\° F[/tex]

We have an absolute change of 18 degrees.

C.

If the change is 5 degrees more, the change would be 18 + 5 = 23 degrees, and the final temperature would be 5 degrees lower, that is:

[tex]Final\ temperature = -3 - 5 = -8\°F[/tex]

Answer:

If the amount of dough for a small pizza is S, for a large pizza is L and for a medium pizza is M, we have the equations:

M = (3/2)*S

L = (5/2)*S

L = M + S

First, we can convine the second and third equation and get:

(5/2)*S = M + S

and now we can replace M by the first equation:

(5/2)S = (3/2)*S + S = 5/2 S

so we have a trivial equation, S can be any number, this means that the system of equation is not well constructed.

For example, if S = 1Kg then:

M = (3/2)kg

L = (5/2)kg = (3/2)kg + 1 kg = 5/2kg

Answer:

The equation for a small pizza is, 3/2s + s = 5/2s.

Next, to combine like terms the equation is, 5/2s = 5/2s.

After that, for opposite operations you write, 5/2s - 5/2s = 0.

When you combine the like terms for the last equation, you come up with,

0 = 0.

The small sized pizza does not have a specific size and is no longer part of the equation. Its' size can be anything, and the other sized pizzas will equal their equation towards the small pizza, still representing their same value.

Step-by-step explanation:

cheese + sauce + dough + lots of meat + fire = happiness/pizza
