Let's convert 8 pounds and 3 ounces, into all ounces.

So we know one pound = 16 ounces.

1 lb = 16 oz.

Now since Omar is 8 pounds + 3 ounces, we multiply 16 by 8, and add on the 3:

16 * 8 = 128

128 + 3 = 131

So Omar weights 131 ounces when he was born.

Now Omar has to gain 5 ounces each week, for 4 weeks. This means in total, he'll have to gain 5*4=20 ounces in 4 weeks.

Add them together:

131 + 20 = 151 oz OR 9 7/16 lb.

An elliptical culvert is 3.5 feet tall and 6 feet wide. It is filled with water to a depth of 0.95 feet. Find the width of the s

maks197457 [2]

Answer:

$W_s \approx5.3$

Step-by-step explanation:

From the question we are told that

Height $H=3.5ft$

Weight $W= 6ft$

Depth $D=0.95ft$

Generally the equation for ellipses is given as

$\frac{x^2}{a^2} +\frac{y^2}{b^2} =1$

Where

$b=H/2\\b=3.5/2\\Therefore\\b=1.75\\a=W/2\\a=6/2\\Therefore\\a=3\\$

$\frac{x^2}{3^2} +\frac{y^2}{1.75^2} =1$

Generally to find y in the equation $\frac{x^2}{a^2} +\frac{y^2}{b^2} =1$

$y=-b+d$

$y=-1.75+0.95$

$y=-0.8$

Therefore

$\frac{x^2}{3^2} +\frac{(0.8)^2}{1.75^2} =1$

$\frac{x^2}{3^2} =1-\frac{(0.8)^2}{1.75^2}$

$\frac{x^2}{3^2} =1-0.2089795918$

$X^2 =3^2(1-0.2089795918)$

$X^2 =7.119183674$

$X =\sqrt{7.119183674}$

$X =2.66817984$

Therefore the width of the given stream is

$W_s=2.66817984*2$

$W_s=5.33635968$

$W_s \approx5.3$

Wingspans of adult horses have approximate normal distribution with mean 125 cm and standard deviation 12 cm. What are the rst a

blagie [28]

Answer:

The first and third quartile of the wingspans are 116.9 cm and 133.1 cm respectively.

Step-by-step explanation:

The first and third quartile of a normal distribution are:

$Q_{1}=\mu-0.675\sigma\\\\Q_{3}=\mu+0.675\sigma$

The information provided is as follows:

$\mu=125\\\sigma=12$

Compute the first and third quartile of the wingspans as follows:

$Q_{1}=\mu-0.675\sigma=125-(0.675\times 12)=116.9\\\\Q_{3}=\mu+0.675\sigma=125+(0.675\times 12)=133.1$

Thus, the first and third quartile of the wingspans are 116.9 cm and 133.1 cm respectively.

Ms. Emily buys a hat and gloves with a coupon for 30% off her entire purchase. The gloves cost $35 before the discount. Her bill

Gennadij [26K]

$44.80=($35+X)(1-0.3)

44.80 is the final total
You need to add the glove and hat cost to get a subtotal (35+x) and then multiply by what is left after the discount 30% off will leave 70% to pay, so in this equation 1-0.3 leaves 0.7 to multiply against the subtotal to get the total before tax of 44.80

The scale on a map shows that 200 miles is represented by 5 inches on a map. Which proportion can be used to find the distance

Ivenika [448]

<em>Answer:</em>

<em>A proportion can be used to find the distance on the map that represents 50 miles, you can calculate this using the following steps: </em>

<em> </em>

<em>200 miles ... 5 inches </em>

<em>50 miles ... x inch = ? </em>

<em> </em>

<em>200 * x = 5 * 50 </em>

<em>x = 5 * 50 / 200 </em>

<em>x = 1.25 inch </em>

<em> </em>

<em>The correct result would be x = 5 * 50 / 200.</em>
