Today I got headaching questions from other subjects and my mind has stopped!☠️ Question number 7, 13, and 16 please

7a) 5/8 cup

7b) 4  3/8 cup

Step-by-step explanation:

a) Divide 1 1/4 by 2:

Do this by putting the 1 into the fraction and then convert to 8th

1 1/4 = 5/4 = 10/8

(10/8)/2 = 5/8

b) 3 1/2 * 1 1/4 = 7/2 * 5/4 = 7*5/(2*4) = 35/8 = 4 3/8

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: 12   they all have at least 28 days

step-by-step explanation: haha
