3. Four chicken nuggets have 180 calories. How many calories are in 9 chicken
Lemur [1.5K]

Hey there! :)

Answer:

405 calories.

Step-by-step explanation:

To solve, we can create a proportion.

We are given that 4 nuggets is equivalent to 180 calories, therefore:

\frac{180cal}{4}= \frac{xcal}{9}

Cross multiply:

9 · 180 = 4 · x

1620 = 4x

Divide both sides by 4:

x = 405 calories.

Can anyone tell me what’s the answer??
maks197457 [2]

Answer:

x = 10

y = 25

Step-by-step explanation:

if you add the equations as they are then the 'y-term' is eliminated:

60x = 600

x = 10

substitute x=10 to find value of 'y':

40(10) + 4y = 500

400 + 4y = 500

4y = 100

y = 25

Check:

20(10) - 4(25) should equal 100

200 - 100 = 100

100 = 100

Given: ∆PST, PT = 8, m∠T = 90°, m∠S = 48° Find: perimeter of ∆PTS
ohaa [14]

Answer:

P=25.98\ units

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The perimeter of triangle PST is equal to

P=PT+PS+TS

step 1

Find the length PS

In the right triangle PST

sin(48\°)=\frac{PT}{PS} ---> opposite side angle of 48 degrees divide by the hypotenuse

substitute the given values

sin(48\°)=\frac{8}{PS}

Solve for PS

PS=\frac{8}{sin(48\°)}

PS=10.77\ units

step 2

Find the length TS

In the right triangle PST

cos(48\°)=\frac{TS}{PS} ---> adjacent side angle of 48 degrees divide by the hypotenuse

substitute the given values

cos(48\°)=\frac{TS}{10.77}

Solve for TS

TS=cos(48\°)(10.77)

TS=7.21\ units

step 3

Find the perimeter

P=PT+PS+TS

we have

PT=8\ units

PS=10.77\ units

TS=7.21\ units

substitute

P=8+10.77+7.21=25.98\ units
