Wanda has eaten 25 of the 28 grapes in her bowl, so she is 25/28 of the way to finishing her snack. Which statement best describ

laiz [17]

<h2>Explanation:</h2><h2 />

No statement provided, so I could help you in a general way. Here we know that Wanda has eaten 25 of the 28 grapes. In other words, we can define this as follows:

$\text{Total number of grapes}=28 \\ \\ \text{Number of grapes she ate}=25$

So we can write this as a percentage form as follows:

$\% \ \text{Grapes eaten}=\frac{25}{28}\times 100 = 89.28\%$

So <em>an statement that is true is that Wanda has eaten almost 90% of the grapes.</em>

A right triangle is given with a missing value of t. It is stated that the triangle is an acute right triangle with angles 50∘ a

sergiy2304 [10]

Answer: t=20°

Step-by-step explanation:

1. By definition, the sum of the interior angles is 180 degrees.

2. Keeping the information above on mind, you can write the following expression:

$90+50+2t=180$

3. Now, you must solve for $t$ as following:

$140+2t=180\\2t=180-140\\2t=40\\t=\frac{40}{2}\\t=20$

4. Therefore, the value of $t$ is 20°

Which expression has the greatest value when x=3

Luden [163]

Answer:

The third expression: (2x)^3

Step-by-step explanation:

Plug in 3 for x in each expression

2x^3

2(3)^3

Use PEMDAS

2 (3 × 3 × 3)

2 (9 × 3)

2 (27)

54

2x^3 + 5

(The last expression told us 2x^3 = 54 so feel free to use this information to make life easier)

54 + 5

59

(2x)^3

(2 × 3)^3

Use PEMDAS

6^3

6 × 6 × 6

36 × 6

216

(x - 1)^3

(3 - 1)^3

Use PEMDAS

2^3

2 × 2 × 2

4 × 2

8

216 is the greatest value so the third expression is the answer
