1. Determine the relationship between the two triangles and whether or not they can be proven to be congruent.​

Step-by-step explanation:

The cost of a cup of tea is t cents.

The cost of a cup of coffee is (t + 5) cents.

The total cost of 7 cups of tea and 11 cups of coffee is 2215 cents.

Therefore,

7t+11t+55=2215

18t=2160

t=120

Answer:

$180

Step-by-step explanation:

(12*10)+(12*5)

12*5 = 120/2 = 60 (half of 12*10)

12*10= 120

120 + 60= $180

You don't even have to calculate (12*5) you can just do 12*10/2

The organization produces short lessons in the form of videos. Its website also includes supplementary practice exercises and materials for educators.

Step-by-step explanation:

The equation of perpendicular line is [tex]$y=-\frac{11}{6} x+\frac{43}{6}[/tex].

The equation of the straight line is represented by

y = mx + c

where m is the slope , and c is the intercept on y axis.

Calculate the slope m of BC using the slope formula

[tex]$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$[/tex]

with [tex]$\left(\mathrm{x}_{1}, \mathrm{y}_{1}\right)=\mathrm{B}(8,4)$[/tex] and [tex]$\left(\mathrm{x}_{2}, \mathrm{y}_{2}\right)=\mathrm{C}(-3,-2)$[/tex]

[tex]$m_{B C}=\frac{-2-4}{-3-8}=\frac{6}{11}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]$m_{\text {perpendicular }}=-\frac{1}{m}=-\frac{1}{\frac{-6}{11}}=-\frac{11}{6}$[/tex], then

[tex]$y=-\frac{11}{6} x+c[/tex]  is the partial equation

To find c substitute A(3,8) into the partial equation

[tex]$9=-\frac{-11}{6}+C[/tex]

[tex]$-\left(-\frac{11}{6}\right)+C=9$$[/tex]

Apply rule -(-a)=a

[tex]$\frac{11}{6}+C=9$$[/tex]

Subtract [tex]$\frac{11}{6}$[/tex] from both sides

[tex]$\frac{11}{6}+C-\frac{11}{6}=9-\frac{11}{6}$$[/tex]

Simplify

[tex]$C=\frac{43}{6}$$[/tex]

[tex]$y=-\frac{11}{6} x+\frac{43}{6}[/tex] be the equation of perpendicular line.

Therefore, the value of c = 43/6.

Hello ^-^

Step-by-step explanation:

Way: W = k * w  * h^2/ L

4 tons is maximum weight that could be supported by a beam that is 6 inches wide, 2 inches high, and 24 feet long

Gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon.

Given,

Maximum weight that a certain type of rectangular beam can support varies inversely as it’s length and jointly as its width and the square of its height.

beam 5 inches wide, 2 inches high and 10 feet long can support a maximum weight of 8 tons.

W = k × w × h²/ L

8 = k × 5 × 2² / 10

8 = k ×20/10

8 = 2 × k

k = 4

The maximum weight that could be supported by a beam that is 6 inches wide, 2 inches high, and 24 feet long

w =4 ×6 ×2² / 24

= 24 ×4/ 24

W=4 tons

Hence 4 tons is maximum weight that could be supported by a beam that is 6 inches wide, 2 inches high, and 24 feet long

Answer:

The answer is C, 17 and | -17|

Step-by-step explanation:

We can solve this using the process of elimination.

Looking at the first one, we know that those | | around the 7 mean to find the absolute value. The absolute value is the number of units the number is from zero, and it is always positive. This means that it is saying 7 and -7. Those are opposites, so we know that this isn't right.

17 and -17 are opposites, since the opposite of a positive is a negative.

The last one is the same. 71 and -71 are opposites. That leaves us with C.

Remember that those | | mean to find the absolute value of. -17 is 17 unites from zero. So is 17 the oppostie of 17? No, so these are not opposites, and therefore are our answer.

Answer:

c) 3ft= 1 yards

18/3 = 6 yards

12/3 = 4 yards

Perimeter- 6×2+4×2=20 yards

6×4=24yards²

d) I foot= 12 inches

18ft = 12×18= 216"
