Answer:

x = 7

Step-by-step explanation:

The angle adjacent to the 70 degree angle is also 70 degrees. We assume that there are four 90-degree angles in the center of the figure. Thus, 8x - 36 + 70 + 90 = 180 (the sum of the interior angles is 180 degrees).

Solving 8x - 36 + 70 + 90 = 180 for x:

8x - 36 = 20, or 8x = 56.

Dividing both sides by 8 yields x = 7.

Solve: log4(7t + 2) = 2

IRISSAK [1]

Answer:

The required value of t is equal to 2

Step-by-step explanation:

We need to solve the following expression :

$\log_4(7t+2)=2$

Now, using the base rule :

$2=\log_4(4^2)\\\\\implies 2= \log_4(16)$

Now, using this value of 2

$\log_4(7t+2)=2\\\\\implies\log_4(7t+2)=\log_4(16)\\\\\implies 7t+2=16\\\\\implies 7t=16-2\\\\\implies 7t=14\\\\\implies t = 2$

Hence, The required value of t is equal to 2

Trisha needs 41/2 yards of fabric to do a project. If she already has2/3 of a yard of fabric, what is the minimum amount of fabr

RUDIKE [14]

We know that
4 1/2----------> (4*2+1)/2--------> 9/2
(2/3)*(9/2)------> 18/6--------->3 yd (this is what Trisha has )
if she has (2/3) she only needs (1/3)

[the minimum amount of fabric she must buy]=(9/2)*(1/3)=1.5 yd

the answer is
the minimum amount of fabric she must buy is 1.5 yd
