Suzette ran and biked for a total of 34 mi in 3.5 h. Her average running speed was 6 mph and her average biking speed was 12.5 m

olga nikolaevna [1]

Answer:

From the information given

x is time for which she ran at speed of 6mi/h and

y is time for which she biked at speed of 12.5 mi/h

total time = 3.5 h

total distance = 34 mi

6x + 12.5y = 34 and

x + y = 3.5

x = 3.5 - y

6 ( 3.5 - y) + y = 34

6.5y = 13 which gives

y = 2 and this

x = 1.5

so suze ran for 1.5 h and biked for 2 h

CHECK

speed of run X time of run + speed of biking x time of biking must be = total distance covered

6 × 1.5 + 12.5 × 2 = 9 + 25= 34 mi

which is true

An aquarium measures 61 cm long, 30.5 cm wide, and 30.5 cm high.If the tank is only filled to 80% capacity with water, how much

LiRa [457]

Answer:

$V=45396.2\ cm^3$

Step-by-step explanation:

Given that,

The dimensions of an aquarium are 61 cm long, 30.5 cm wide, and 30.5 cm high.

The tank is filled to 80% capacity with water.

We need to find the water needed for this tank.

The volume of cuboid is given by :

$V=lbh$

As it is filled to 80% capacity, so,

$V=\dfrac{80}{100}\times lbh\\\\=0.8\times 61\times 30.5\times 30.5\\\\V=45396.2\ cm^3$

So, $45396.2\ cm^3$ of water is needed for this tank.

Find the value of x. m∠IHG = 162° m∠IHK = (4x + 4)° m∠KHG = (8x + 2)°

kirill [66]

Answer:

Step-by-step explanation:

<IHG = 162

<IHK = 4x + 4

<KHG = 8x + 2

<IHG + <IHK + <KHG = 180° (sum of angles in a triangle is equal to 180°)

See attachment for better illustration of the triangle

162 + (4x + 4) + (8x + 2) = 180

162 + 4x + 4 + 8x + 2 = 180

168 + 12x = 180

Collect liketerms

12x = 180 - 168

12x = 12

x = 1
