The actual length of side y is 22cm. Use the scale drawing to find the length of side x.

kozerog [31]

Given:

The actual length of side y is 22cm.

To find:

The length of side x by using the scale drawing.

Solution:

We know that the corresponding sides of original figure and scale drawing are proportional.

$\dfrac{x}{1.8}=\dfrac{y}{1.4}$

$\dfrac{x}{1.8}=\dfrac{22}{1.4}$

$x=\dfrac{22}{1.4}\times 1.8$

$x\approx 28.286$

Therefore, the length of side x is about 28.286 cm.

If the measure of an angle is 78 less than the measure of its compliment, what is the measure of the angle?

aliina [53]

Complementary angles add up to 90'
So let X= angle 1
Y=angle 2
So x+y=90
let x=y-78
so(y-78)+y=90
y-78+y=90
2y-78=90
2y=90+78
2y=168
y=168/2
y=84
x=y-78
so x=84-78
x=6
And 6+84=90
So the measure of the angle is 6 degrees.
Hope i helped!

The weights of bags of grasecks chocolate candies are normally distributed with a mean of 4.3 ounces and a standard deviation of

skelet666 [1.2K]

Answer: 0.2743

Step-by-step explanation:

Let X be a random variable that represents the weight of bags of grasecks chocolate candoes.

X that follows normal distribution with, Mean = 4.3 ounces, Standard devaition = 0.05 ounces

The probability that a bag of these chocolate candies weighs less than 4.27 ounces : $P(X$

$=P(z$

Hence, the required probability = 0.2743
