Will mark brainliest if correct. Find what the measurement of angles a-d are and state the reason
Furkat [3]

Answer: D = 70  

              A = 30

Explanation: d is parallel to 70 degrees, 40 is parallel to e, and the whole set of angles is 180 so 180 - 2(70) + 2(40)  = 30 so D = 70 and A = 30

Jeremy claims that if a linear function has a slope of the same steepness and the same y-intercept as the linear function in the
andre [41]

Here, we have to examine the equation of the straight line which is denoted by: y = m x +c where "m" is the slope which represents the steepness and c is the y-intercept

Here, the two linear functions have the same slope "m" and the same y-intercept "c". When both these are the same, the two linear functions are representing the same straight line.

Therefore, Jeremy is correct in his argument.

You are planning a new production floor. You will need space for eight manufacturing processes and six stockpiles. Each takes 16
mina [271]

Answer:

Total space needed is 3136 square feet.

Step-by-step explanation:

We are given the following in the question:

Space required for eight manufacturing processes and six stockpiles.

Each takes 160 square feet.

Space required for 8 process =

=8\times 160\\=1280\text{ square feet}

Space required for 6 stockpiles =

=6\times 160\\=960\text{ square feet}

Total space =

=1280 + 960\\=2240\text{ square feet}

Open space required = 40%

=\dfrac{40}{100}\times 2240\\\\=896\text{ square feet}

Total space required =

=2240 + 896\\=3136\text{ square feet}

Thus, total space needed is 3136 square feet.
