In order to take honors-level math, Lisa must have an average of 85 on her math tests. Her scores so far are 85, 70, and 98. Wha

Mila [183]

Answer:

d) 87

Step-by-step explanation:

to solve this lets set up the equation

$\frac{85+70+98+x}{4} =85\\\frac{253+x}{4} =85$

then we multiply 4 on both sides

253+x=340

and subtract 253 on both sides

x=87

to double check take the averages

(87+85+70+98)/4=85

Sean tried to drink a slushy as fast as he could. He drank 5 milliliters of slushy each second and finished all

castortr0y [4]

Answer:

graph like this:

Step-by-step explanation:

First, in 5 seconds, we know that he drinks 25 mL of slushy. We know this because 1 second is 5 mL, so 5 seconds is 25 mL. So, your graph should be going from the 5 second to 25 mL mark, then the 10 second and 50 mL mark, then the 15 mL and 75 mL mark, and so on.

State what additional information is required in order to know what the triangles are congruent by SSS.

soldi70 [24.7K]

Answer:

see below

Step-by-step explanation:

In order to show congruence by SSS (Side-Side-Side), you need to have 3 pairs of sides congruent. The diagram shows two pairs congruent (those of choice B), so you need information that the third pair of sides is congruent, choice D.

Any answer choices involving angles are irrelevant for SSS congruence.

Graph y=sin^-1 (1/4 x) on the interval -5≤x≤5.

GaryK [48]

Answer:

Step-by-step explanation:

The arcsine ( $\sin^{-1}$ ) function of x is defined as the inverse sine function of x when -1≤x≤1.

So, when

$-4\le x\le 4,$

we have that

$-1\le \dfrac{1}{4}x\le 1.$

This gives us the domain $-4\le x\le 4$ of the function $y=\sin^{-1}\left(\dfrac{1}{4}x\right).$

The range of the function $y=\sin^{-1}x$ is $-\dfrac{\pi }{2}\le x\le \dfrac{\pi }{2},$ so the range of the function $y=\sin^{-1}\left(\dfrac{1}{4}x\right)$ is the same (options A and C are false).

When x=-4,

$y=\sin^{-1}\left(\dfrac{1}{4}\cdot (-4)\right)=\sin^{-1}(-1)=-\dfrac{\pi}{2}.$

So, option B is false and option D is true.
