Answer:
x = 48.
Step-by-step explanation:
If AE is 921, then EC is equivalent to that. First, you subtract 9 from 921, then divide by nineteen to get your answer: x = 48.
Answer:90minutes
Step-by-step explanation:
Speed=distance/time
Speed=40miles per hour, distance=60miles
40=60/t
Cross multiply
40t=60
Divide both sides by 40
40t/40=60/40
t=1.5 hour =90minutes
The value k needed for the transformation of f(x) to g(x) = f(k · x) is equal to 3.056.
<h3>How to find the find the dilation factor</h3>
In this problem we have the following relationship bewteen the two <em>quadratic</em> equations: g(x) = f(k · x), which means that for all y the following relationship between f(x) and g(x):

Let suppose that y = 3, then
and
, then the value k is:
k = (- 5.5)/(- 1.8)
k = 3.056
The value k needed for the transformation of f(x) to g(x) = f(k · x) is equal to 3.056.

She can cut 4 pieces from the ribbon.
Explanation:
Draw altitude AD to segment BC such that point D is on BC. This creates right triangles ADB and ADC.
Hypotenuses AB and AC are given as congruent. Leg AD in each triangle is congruent to itself by the reflexive property of congruence.
Then the triangles ADB and ADC are congruent by the HL congruence theorem.
Angles B and C are corresponding parts of congruent triangles, so are congruent by CPCTC.
