Answer:

<u>The approximate total weight of the grapefruits, using the clustering estimation technique is B. 35 ounces.</u>

Step-by-step explanation:

We notice that the weights of the grapefruits given are slightly down or above 7, then we will use <em>7 as our cluster</em> for the estimation, as follows:

Weights

7.47 ⇒ 7

7.23  ⇒ 7

6.46  ⇒ 7

7.48  ⇒ 7

6.81  ⇒ 7

<u>Now we can add up 7 + 7 + 7 + 7 + 7 for the weights of the grapefruits and the approximate total weight is B. 35 ounces.</u>

original length of the thread, L₀ = 10 m = 1000 cm

the length of the thread used, L₁ = 210 cm

The length of the thread remaining is calculated as follows;

ΔL = L₀ - L₁

ΔL = 1000 cm - 210 cm

ΔL = 790 cm

Therefore, the length of the thread remaining is 790 cm

Graph a triangle on the coordinate plane. Choose 1 transformation (reflection, rotation,
BlackZzzverrR [31]

Answer:

The answer in the procedure

Step-by-step explanation:

we have the right triangle ABC

The pre-image coordinates are

A(0,0),B(0,3),C(4,0)

The transformation to use is the translation

The rule of the translation is

(x,y)-----> (x+10,y)

That means----> The translation is 10 units to the right

The image coordinates are

Applying the rule of the translation

A'(0+10,0)=A'(10,0)

B'(0+10,3)=B'(10,3)

C'(4+10,0)=C'(14,0)  

using a graphing tool

see the attached figure
