Can someone answer this question please please help me I really need it if it’s correct I will mark you brainliest .

Answer:

Step-by-step explanation:

m -38 = 15

m = 53

the answer is 1

Answer: the answer to your question is 53...

Explanation: I know I'm super late but let me explain why it's 53...

If you go on a calculator and type 53+ (-38) the answer would be 15 which can only mean that M=53. That is why it is 53 go try it out...

like I said I'm sorry I'm late...    Brainliest?

Answer: A - 8

Step-by-step explanation:

7 equals 6 plus AB divided by 2

7 times 2 is 14

14 - 6 = 8

Answer: p = -11.4

Step-by-step explanation: –5.7p = –14.82 − 7p

                                             –5.7p = –14.82 + − 7p

                                             –5.7p = -7p - 14.82

                                             –5.7p + 7p = -7p - 14.82 + 7p

                                             1.3p = -14.82

                                             1.3p/1.3 = -14.82/1.3

                                             p = -11.4

Answer:

Added 7.4y + 11.2y

Step-by-step explanation:

Let's solve the equation our self and see what the actual solution is,

11.2y - 7.4y = 141.36

→ Multiply everything by 100 to get rid of the decimal's

1120y - 740y = 14136

→ Simplify the 'y' terms

380y = 14136

→ Divide both sides 380 to isolate 'y'

y = 37.2

-------------------------------------------------------------------------------------------------------

The answer is "added 7.4y + 11.2y" because if we use that method then,

7.4y + 11.2y = 141.36

→ Collect the 'y' terms

18.6y = 141.36

→ Divide both sides by 18.6 to isolate y

y = 7.6

Answer:

5^18.

Step-by-step explanation:

By the law of indices:

Step-by-step explanation:

First, add each number in the set of data. Then, divide the sum by the count of numbers in the data set.

example:

DATA SET:

5 4 7 6

MEAN STEP 1:

5 + 4 + 7 + 6 = 22

MEAN STEP 2:

Since there are four numbers in the data set, divide 22 by four.

Answer:

Sample Answer: First, find the mean of the data set by averaging. Next, find the absolute deviations for each data point. That is, find the distance each point is from the mean. Then find the mean of the absolute deviations.

Which did you include in your explanation? Check all that apply.

Find the mean of the set of data.

Find the absolute deviations for each point.

Absolute deviation is a data point’s distance from the data set’s mean.

Find the mean of the absolute deviations.

Answer:

Volume flow rate, Q, into the tank is 12.376 m³

Step-by-step explanation:

Here we have Bernoulli's equation presented as follows

[tex]\frac{P_{1}}{\rho _{1}g}+\frac{v_{1}^{2}}{2g} + z_{1} = \frac{P_{2}}{\rho _{2}g}+\frac{v_{2}^{2}}{2g} + z_{2}[/tex]

Where:

P₁ = Pressure, of the open tank = Atmospheric pressure = 0

P₂ - Pressure at the discharge of the pipe = Atmospheric pressure = 0

ρ₁ = Density of the fluid = ρ₂

v₁ = Velocity of the fluid in the tank

v₂ = Velocity of the fluid in the pipe

d₁ = Diameter of the tank = 1.5 m

d₂ = Diameter of the pipe = 15 cm = 0.15 m

A₁ = Cross sectional area of tank = π×d₁²/4 = 1.767 m²

A₂ = Cross sectional area of pipe= π×d₂²/4 = 0.01767 m²

z₁ = Level of water in the tank = 0 m

z₂ = Level of water in the pipe = 2.5 m

Whereby the level remains constant at 2.5 m, pressure at the base, P₂ = ρ₁×g×2.5

Also

v₁×A₁ = v₂×A₂ which gives;

v₁×1.767  = v₂×0.01767

v₂ = v₁×1.767/0.01767 = 100·v₁

Hence we have;

[tex]\frac{0}{\rho _{1}g}+\frac{v_{1}^{2}}{2g} + z_{1} = \frac{0}{\rho _{1}g}+\frac{(100v_{1})^{2}}{2g} + z_{2}[/tex]

[tex]z_{1} - z_{2} = \frac{(100v_{1})^{2}}{2g}- \frac{v_{1}^{2}}{2g}[/tex]

[tex](2.5)2g = 99v_{1}^{2}}[/tex]

v₁² = 2.5×2×9.81 = 49.05

v₁ = √49.05 = 7.0035 m/s

Therefore, since the rate of discharge = Rate of entry into the tank, we have;

Volume flow rate, Q, into the tank = v₁×A₁ = 7.0035 m/s × 1.767 m² = 12.376 m³.

Answer:

Antarctica's highest recorded temperature was 15 degrees.

Step-by-step explanation:

I am going to say that Antarctica highest recorded temperature is x.

I suppose there is a small typing mistake.

It is that the difference between Antarctica highest recorded temperature and this is 49.44.

So we have that x - (-34.44) = 49.44 instead of -34.44 - x = 49.44, which would lead to a highest temperature way lower than the one recorded in this winter.

So

x - (-34.44) = 49.44

x + 34.44 = 49.44

x = 49.44 - 34.44

x = 15

Antarctica's highest recorded temperature was 15 degrees.

Answer:

15 degrees

Hey there! I'm happy to help!

To find the volume of a cone, you take the area of the base, multiply it by the height and divide it by three.

We see that the radius of our base is three. To find the area of the base, we will square the radius and multiply it by 3.14 (formula for area of circle).

3²=9

9×3.14= 28.26

We multiply it by the height.

28.26(2)=56.52

We divide it by three.

56.52/3=18.84

Therefore, the area is 18.84 units cubed.

Now you can find the volume of cones! I hope that this helps! Have a wonderful day!

Answer:

A.) $61682.97

B.) $11,682.97

Step-by-step explanation:

Initial deposit (A) = $50000

Period(t) = 4 years

Interest(r) = 5.25% annually,

n = number of times interest is compounded

Amount of the CD in four years :

Compound interest formula :

A = final amount

A = P(1 + r/n) ^nt

A = $50,000( 1 + (0.0525/365))^365×4

A = $50,000( 1 + 0.00014383562)^1460

A = $50,000(1.00014383562)^1460

A = $50,000(1.23365943637930)

A = $61682.9718189651

B.) Interest = $61682.97 - $50,000

Interest = $11,682.97

Answer:

The value of x = 4

Step-by-step explanation:

In this question, we are asked to calculate the value of the angle x

Here the ray cuts the angle into half.

Since the total of the angle was 120, half of this would be 120/2 = 60

Now, it is this value of 60, that our new angle equals to

Mathematically;

3x + 48 = 60

3x = 60-48

3x = 12

x = 12/3

x = 4

1ans) 6/14 or 3/7 probability

2ans) 1/2 or a 50% chance

Answer:

$1500

Step-by-step explanation:

Let's start by converting 80% to a decimal. 80% means 80/100, or 0.8. Let's call the full budget b.

0.8b=1200

Divide both sides by 0.8 to isolate b:

b=1200/0.8=$1500

Answer:

c = 45.33, C =97°, a = 40, A = 61.15° , B = 21.85°, b = 17

Step-by-step explanation:

Given that:

C = 97°, a = 40 and b = 17.

We have angle C, we need to find the side the side c opposite to the angle C. we have side a, we need to find the angle A opposite to side a. we have side b, we need to find the angle B opposite to side b.

Using cosine rule:

c² = a² + b² - 2ab × cos(C)

c² = 40² + 17² - 2(40)(17)cos(97)

c² = 2054.74

c = 45.33

Also using sine rule:

[tex]\frac{a}{sin(A)} =\frac{c}{sin(C)} \\\frac{40}{sin(A)}=\frac{45.33}{sin(97)} \\sin(A)=\frac{sin(97))40}{45.33}=0.876\\A=sin^{-1}(0.876)=61.15^0[/tex]

Also:

[tex]\frac{b}{sin(B)} =\frac{c}{sin(C)} \\\frac{17}{sin(B)}=\frac{45.33}{sin(97)} \\sin(B)=\frac{sin(97))17}{45.33}=0.3722\\B=sin^{-1}(0.3722)=21.85^0[/tex]

c = 45.33, C =97°, a = 40, A = 61.15° , B = 21.85°, b = 17

Answer:
