What is the inequality?
erica [24]

Answer:

D

Step-by-step explanation:

Given

21 ≤ - 3(x - 4) < 30

Divide all intervals by - 3, reversing the inequality symbols as a result of dividing by a negative quantity.

- 7 ≥ x - 4 > - 10 ( add 4 to each interval )

- 3 ≥ x > - 6, that is

- 6 < x ≤ - 3 → D

What are the coordinates of B' if the origin is the center of dilation and the scale factor is 1/4?
Deffense [45]

Answer:

B' (1, 2 )

Step-by-step explanation:

Since the centre of dilatation is the origin then multiply the coordinates of B by the scale factor.

B (4, 8 ) → B' (4 × \frac{1}{4} , 8 × \frac{1}{4} ) → B' (1, 2 )

If 3 tan theta = 3 sin theta then find the value of sin theta
AleksandrR [38]
Answer: 0 radians

Explanation: Looking at the unit circle, tan and sin equal each other at 0 radians. Sin(0) = 0 and tan(0) = 0/1 = 0.
Therefore, theta equals 0. Multiplying by 3 does not matter in this case because it is being multiplied by 0. Any number multiplied by 0 is 0.

Yan is climbing down a ladder. Each time he descends four rungs on the ladder, he stops to see how much farther he has to go. Wh
kykrilka [37]

Answer:

"descends"

Step-by-step explanation:

The word descend means to move or fall downwards. If we were to think of the ladder as the y-axis of a coordinate grid we could see that as you move further down on the axis the numbers turn to negative which indicate that the word descend means that a negative integer should be used :)

Answer:

1. 500mg

2.A watermelon weighs about 3 (grams /(kilograms) 3.

3. 500 oranges

4. 30 weeks

5. 1500

Step-by-step explanation:

1. Therefore, 0.5 g=0.5*1000=500 mg

2. A watermelon weighs about 3 (grams /(kilograms) 3.

3.Weight of the box- 40 kg

Weight of 1 orange-80

Therefore, no. of total oranges=

40 kg=40000g

Now, 40000÷80

= 500

4. 500g x 2 is 1000 g and is 1kg

105-90 is equal to 15kg

500 x 30 is 15000 g is equal to 15 kg

5. divide by 4 to get the mass of a single bag and then multiply by 1000 to get to grams from kilograms

6/4=1.5

1.5*1000=1500

therefore a single bag of sugar weighs 1500 grams
