Given triangle is a right angle triangle so we are allowed to use trigonometric formulas.

We want to find Hypotenuse using angle A and base 7 cm

so right choice is to use cosine

\cos(A)=\frac{AC}{AB}

\cos(25^{\circ})=\frac{7}{AB}

0.90631=\frac{7}{AB}

AB=\frac{7}{0.90631}

AB=7.72362657369

Hence value of side AB is approx 7.72 cm.

Please answer this it’s very hard for me
Nimfa-mama [501]

Answer:

C, D, E, F

Step-by-step explanation:

Remember y=mxb?

m is slope and b is y-intercept

so y=2/7x-9

Remember that slope is RISE/RUN so for every 2 squares that you go up, you go 7 squares to the right.

Also remember that since your graph is going thru your Cartiesian Plane in quadrent 4, your y value in your ordered pairs will most probably be a negative.

Please see the image to help you viualize this.

Why isn’t the maximum ACT score (36) at the 100th percentile?
irga5000 [103]

Answer and Explanations

ACT score percentile help colleges compare students with one another, rather than just looking at everyone’s score. The  score range is between 1 and 36, the highest score that one can receive on the ACT is 36. Moreover, 36 is the perfect score.

The maximum ACT score (36) is that in 2018, only 3,741 students (out of millions of test-takers) scored a perfect 36 on the ACT.  The 99th percentile of test-takers includes those who earn 35 or 34 on the ACT. We can miss up to five questions on the ACT and still earn a 36. That is a reason why the maximum ACT score is 36 at the 100th percentile.

The ACT score report will provide more information about test-taking experience in the form of sub score. The higher the score,  you will get into the colleges of your choice.

Tina is saving to buy a notebook computer. She has two options. The first option is to $400 away initially and save $30 every mo
LuckyWell [14K]

Answer:

Let n represent the number of months after Tina would save the same amount using either option.

400 + 30n = 100 + 50n

400 + 30n − 30n = 100 + 50n − 30n Subtraction Property of Equality

400 = 100 + 20n            Combine like terms.

400 − 100=100 + 20n − 100 Subtraction Property of Equality

300 =20n

300

20

 =  

20n

20

15 months=n

After 15 months, Tina will save the same amount using either option.

400 + 30(15)=100 + 50(15)

400 + 450=100 + 750

850 = 850

After 15 months, Tina will save $850 with either option.
