What is the area of triangle with base 5m and height 12m

Ksivusya [100]

The area of a triangle can be found using the formula 1/2bh, where the variable b represents the value of the base and the variable h represents the value of the height.

If we plug in the given values into this formula, we get:

(1/2)(5m)(12m)

When we simplify this expression, we get:

30 m^2

Therefore, your answer is 30 m^2.

Hope this helps!

Find the measure of angle x in the figure below:<br> 60°<br> 50°<br> 110°<br> 70°

Rina8888 [55]

Answer:

Step-by-step explanation:

Consider A=60°, B=50°, C=y°=???

So, according to the measurement of angles of a triangle.

A+B+C= 180°

60°+80°+C= 180°

140°+C=180°

C=180°-140°

C=y°=40°

So, x is also 40° since x and y are vertically opposite angles.

Arthur has 6 more than 5 times the number of pencils as Jenny. If Arthur and Jenny combined have 30 pencils, how many pencils do

pashok25 [27]

Answer:

Jenny has 4 pencils.

Step-by-step explanation:

Let

Jenny has pencils = x

Arthur has pencils = 5x+6 (Arthur has 6 more than 5 times the number of pencils as Jenny. )

Total pencils = 30

We need to find how many pencils does Jenny have.

We basically can write the equation:

Total pencils = Jenny pencils + Arthur pencils

Putting values and solving to find value of x:

$30=x+5x+6\\30=6x+6\\30-6=6x\\24=6x\\=> 6x=24\\x=\frac{24}{6}\\x=4$

So, we have value of x = 4

Now, finding number of Jenny pencils:

Jenny has pencils = x = 4

Therefore, Jenny has 4 pencils.

66 is what%of 74 just wanna know what grade I got it isn't telling me. and also I am not using google cause I want someone to ge

Elodia [21]

Hello!

Let's write this as an equation.

74x=66

Now let's solve by dividing both sides by 74.

x≈0.89

Now we multiply by 100 to make it a percent.

0.89(100)= 89

Therefore, our answer is 89%

I hope this helps!

The temperature of a cup of coffee varies according to Newton's Law of Cooling: dT dt equals negative k times the quantity T min

Maslowich

Answer:

67.3°C

Step-by-step explanation:

A = 25, T(0) = 100, T(1) = 90, find T(4)

dT/dt = -k(T - A)

d(T - A)/dt = -k(T - A)

d(T - A)/(T - A) = -k dt

ln(T - A) = lnC - kt

$T(t) -A=Ce^{-kt}\\T(t) = A + Ce^{-kt} = 25 + Ce^{-kt}\\T(0) = 25 + C = 100\\C=75$

$T(t) = 25 + 75e^{-kt}\\T(1) = 25 + 75e^{-k} = 90\\75e^{-k} = 65\\e^{-k} = \frac{65}{75}, k = ln\frac{75}{65} = 0.1431\\T(t) = 25+75e^{-0.1431t}\\T(4) = 25+75e^{-0.1431\times4} = 67.3$
