Answer:

Step-by-step explanation:

∠A + ∠B + ∠C = 180 { Angle sum property of triangle}

42 + ∠B + 60 = 180

∠B + 102 = 180

∠B = 180 - 102 = 78

In similar triangles, corresponding angles are congruent.

∠S ≅ ∠B

∠S = 78°

vampirchik [111]

Answer:

$m=\frac{-3}{4}$

Step-by-step explanation:

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Simply plug in 2 coordinates into the slope formula to find slope m:

$m=\frac{-4-(-1)}{5-1}$

$m=\frac{-4+1}{4}$

$m=\frac{-3}{4}$

jasenka [17]

Answer:

190 baskets of strawberries

Step-by-step explanation:

The question is incomplete as it didn't state what we are to determine from the information given.

Let's determine total amount picked in the three days.

1st day picked 90strawberries

Amount of strawberries on 2nd day = 2/3 of the amount picked 1st day

= (2/3)(90)

Amount of strawberries on 2nd day = 60 baskets of strawberries

Amount of strawberries picked on 3rd day = (2/3) of the amount picked 2nd day

= (2/3) (60)

Amount of strawberries picked on 3rd day = 40 basket of strawberries

Total amount picked for 3 days = 90+60+40

= 190 baskets of strawberries

"A serving of fish contains 50 g protein and 4 g of fat. If protein has a caloric value of 4 kcal/g and fat has 9 kcal/g, how ma

evablogger [386]

Answer: 236 kcal

Step-by-step explanation:

Given : A serving of fish contains 50 g protein and 4 g of fat.

i.e. content of protein = 50 g

content of fat = 4 g

Also, The caloric value in protein = 4 kcal/g

The caloric value in fat = 9 kcal/g

Calories in 50 g protein = (content of protein)x (caloric value in protein )

= 50g x 4 kcal/g = 200 kcal

Calories in 4 g fat= (content of fat)x (caloric value in fat)

=4 g x 9 kcal/g = 36 kcal

Then, the total calories in the serving will be :Calories in 50 g protein + Calories in 4 g fat

= 200 kcal+ 36 kcal =236 kcal

Hence, there are 236 kcal in the serving.
