Miyoko's goal is to earn more than \$950$950dollar sign, 950 this week. She earns \$250$250dollar sign, 250 for every day she works as a cryptographer, and earns \$180$180dollar sign, 180 for every day she works as a geologist. Write an inequality that represents the number of days Miyoko should work as a cryptographer (C)(C)left parenthesis, C, right parenthesis and as a geologist (G)(G)left parenthesis, G, right parenthesis to achieve her goal.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

answer is  

a.

p = 78

step-by-step explanation:

so mark-up is 0.4 multiplied by 180 = 72
