Answer:
5.7
Step-by-step explanation:
pythagorean theorem
A^2 + B^2 = C^2
sub in
A^2 + 7^2 = 9^2
simplify
A^2 + 49 = 81
solve
A^2 = 32
solve further
A = 
use calculator and get:
5.65685
round and get:

The model of the granola bars is an illustration of <em>ratios and proportions</em>.
The model that shows the total serving is model A
The given parameters are:


So, the number of servings in both bars is:

Substitute 2 for Bars and 2/5 for Servings

Express as multiplication



The total number of servings is 5
The model that shows a total serving of 5 is model A (see attachment)

Answer:
the length of PQ is equal to the length of P'Q'
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.
Translation is the movement of a point either up, down, right or left. Translation is a type of rigid transformation. Rigid transformation is a transformation in which both the image and pre-image have the same shape and size. types of rigid transformation are rotation, reflection and translation.
Quadrilateral PQRS is translated to the left by 4 units to obtain another quadrilateral P᾿Q᾿R᾿S᾿. Since translation is a rigid transformation, the shape and size of PQRS is the same as that of P'Q'R'S. Hence the length of PQ is equal to the length of P'Q'.
Answer:
Andrew takes a test for the disease that has an accuracy rate of 75%. What is the probability that Andrew has heart disease and the test accurately predicts it? The two events are independent, so you need to find the product of their probabilities: 0.9 × 0.75 = 0.675.
