Jade got a 90% on her math quiz. She had 36 questions correct. How many questions did Jade get wrong?

Brums [2.3K]

Answer:

4 questions

Step-by-step explanation:

90% is the same as multiplying a number by 0.9. Let's say the number of questions on the quiz is x. This means the amount she got right was 0.9x. We are given this is 36, so we can set them equal and simplify:

0.9x = 36

x = 40

She must have gotten 40 - 36, or 4 questions wrong.

Find the center, vertices, and foci of the ellipse with equation 2x2 + 8y2 = 16.

Pavlova-9 [17]

${2}x^{2} + 8 {y}^{2} = 16 \\ \\ 1. \: {2x}^{2} = - 8 {y}^{2} + 16 \\ 2. \: {x}^{2} = - 4y^{2} + 8 \\ 3. \: x = \sqrt{ - 4y^{2} + 8} \\ x = - \sqrt{ - 4y^{2} + 8 } \\ \\ answer \\ x = \sqrt{ - 4y^{2} + 8 } \\ x = - \sqrt{ - 4y^{2} + 8}$

A recipe calls for cup of broth. The largest volume-measuring tool that Tabitha has is a teaspoon. She knows that there are 16 t

Artist 52 [7]

1c = 16t = x( $\frac{1}{3}$ )
1c = 16t = 16 X 3
1c = 16t = 48

She should use 48 teaspoons of broth.
