m∠A = 40

Step-by-step explanation:

Given AB =AC and m∠B = 70

Since AB =AC , Triangle ABC is an isosceles Triangle and the corresponding angles B and C are equal.

So m∠B = m∠C = 70

The sum of the 3 Angles of a triangle is 180°.

=> m∠A + m∠B + m∠C = 180

=> 140 + m∠C = 180

=> m∠C = 40

Hence the answer is m∠C = 40

A physician orders 140mg of a medication to give orally. You have 125mg/5mL on hand. What is the correct dose of medication to g

adelina 88 [10]

<h2>Hello!</h2>

The answer is: The correct dose of medication to give is 5.6 mL

To solve this problem we need to establish a relationship between the prescripted medication and the available solution.

Let's write the needed equations to establish the relantionship:

$\frac{125mg}{5mL}=1\\\\125mg=5mL$

The available solution means 125 mg each 5 mL of solution, so:

$\frac{125mg}{5mL}=\frac{140mg}{x}\\\\x*\frac{125mg}{5mL}=140mg\\\\x=140mg*\frac{5ml}{125mg}=\frac{700mg*mL}{125mg}=5.6mL$

Hence, the correct dose of medication to give is 5.6 mL of the 125 mg/5mL solution.

Have a nice day!

Emily Runs 10 ft./s Jake runs 334 feet and 26 seconds Katie runs 1 mile in 596 seconds and Stephanie runs 580 feet in one minute

Jake runs fastest

Step-by-step explanation:

The given is:

Emily Runs 10 ft./s
Jake runs 334 feet in 26 seconds
Katie runs 1 mile in 596 seconds
Stephanie runs 580 feet in one minute

We need to find who runs fastest

To solve the problem we must to find the unit rate of each one in feet per second

∵ Jake runs 334 feet and 26 seconds

- To find the unite rate divide 334 feet by 26 seconds

∴ Jake's rate = 334 ÷ 26 = 12.85 ft./s

∵ Katie runs 1 mile in 596 seconds

- Change the mile to feet

∵ 1 mile = 5280 feet

∴ Katie runs 5280 feet in 596 seconds

- To find the unite rate divide 5280 feet by 596 seconds

∴ Katie's rate = 5280 ÷ 596 = 8.86 ft./s

∵ Stephanie runs 580 feet in one minute

- Change the minute to seconds

∵ 1 minute = 60 second

∴ Stephanie runs 580 feet in 60 seconds

- To find the unite rate divide 580 feet by 60 seconds

∴ Stephanie's rate = 580 ÷ 60 = 9.67 ft./s

∵ Emily's rate is 10 ft./s

∵ Jake's rate is 12.85 ft./s

∵ Katie's rate is 8.86 ft./s

∵ Stephanie's rate is 9.67 ft./s

- The fastest one who has the greatest rate

∵ Jake's rate is the greatest

∴ Jake runs the fastest

Jake runs fastest
