What is the length of ED

Mathematics
1 answer:
STALIN [3.7K]3 years ago
4 0

Answer:

ED ≈ 2.6 units

Step-by-step explanation:

Using the Sine rule in Δ DEF

\frac{FD}{sin115} = \frac{ED}{sin20}

\frac{6.95}{sin115} = \frac{ED}{sin20} ( cross- multiply )

ED sin115° = 6.95 sin20° ( divide both sides by sin115° )

ED = \frac{6.95sin20}{sin115} ≈ 2.6 ( to the nearest tenth )

4a + 2z = 10<br>-3a + Z = -10<br>What is the value of 10a​
vredina [299]

Answer:

10a = 30

Step-by-step explanation:

By using elimination:

4a + 2z = 10

-2(3a + z) = -2(-10)

4a + 2z = 10

6a - 2z = 20

2z and -2z cancel out

10a = 30

a = 3

They are asking for 10a, so 10 (3) = 30.

A local water storage facility is currently empty. The city
Semenov [28]

Answer: See explanation

Step-by-step explanation:

a) How much-water will be in the water storage facility in 25 minutes?

Since the city water workers begin filling it at a rate of 500 gallons per minute, in 25 minutes they'll have filled:

= 500 × 25

= 12500 gallons

It immediately begins sending some of its water into the city's water pipes at a rate of 150 gallons per minutes. In 25 minutes, they'll have sent:

= 150 × 25

= 3750 gallons

Amount that'll be left in the tank will be:

= 12500 - 3750

= 8750 gallons

b. Write an equation to find the number of gallons,y,in the storage facility after x minutes. This will be:

y = (500 × x ) - (150 × x)

y = 500x - 150x

y = 350x
