Cristy has ten pets including cats, birds, and hamsters. She has twice as many hamsters as cats.

1 answer:

6 0

6 hamsters, 3 cats, and 1 bird = 38 legs.

6H + 3C + 1B = 30

H = 4 C = 4 B = 2

6*4 + 3*4 + 1*2 = 38

Hope this helped :)

2 questions geometry :) thanks if you answer

Answer:

Part 1) An expression for the x-coordinate of T is (a+2)

Part 2) The value of x=39 ft (see the explanation)

Step-by-step explanation:

Part 1)

step 1

we know that

The rule of the reflection of a point across the x-axis is equal to

$(x,y) -----> (x,-y)$

Apply the rule of the reflection across the x-axis to the Q coordinates

Q (a,b) ----------> Q'(a,-b)

step 2

The translation is 2 units to the right

The rule of the translation is

(x,y) ----> (x+2,y)

Apply the rule of the translation to the Q' coordinates

Q'(a,-b) -----> T(a+2,-b)

therefore

An expression for the x-coordinate of T is (a+2)

Part 2)

we know that

A reflection is a rigid transformation, the image is the same size and shape as the pre-image

In this problem the floor plan house A and the floor house B have the same size and shape

That means that its corresponding sides and corresponding angles are congruent

therefore

The value of x=39 ft

A plumber charges $25 for a service call plus $50 per hour of service. Write an equation in slope-intercept form for the cost, C

krok68 [10]

Answer:

C = 25 + 50h

Step-by-step explanation:

cost for zero hours is $25, so that is the y-intercept of the graph.

each hours adds a cost of $50, so that is the gradient of the graph. These two values give us our equation in slope-intercept form.

If the calculated test statistic is 2.148 when the critical value is 2.348, should you reject or not reject the null hypothesis,

Lisa [10]

The approach of critical value is used to determine likely or unlikely through determination whether observed test statistics is more than it would have been if null hypothesis was true. In other words, test statistics is compared to critical value and decision made.
If test statistics is more than critical value, the null hypothesis is rejected. Otherwise, null hypothesis is not rejected.

In the current scenario, test statistics (2.148) is less than critical value (2.348) and thus null hypothesis is not rejected.
