Answer:

Step-by-step explanation:

First ,we round 1.79 to the nearest whole dollar:

since 7 ≥ 5 then 1.79 rounded to the nearest whole dollar is 2

now ,we can estimate the greatest number she can download:

26/2 = 13

Answer:

$a. \: 28$

$b. \: 5$

Step-by-step explanation:

$a. \: 88 \div 3 \frac{1}{7}$

$88 \div \frac{22}{7}$

Multiply the numerator by the reciprocal of the denominator.

$88 \div \frac{7}{22}$

$4 \times 7$

$28$

$b. \: 49 \frac{2}{9} \div 9 \frac{4}{9}$

$\frac{425}{9} \div \frac{85}{9}$

Multiply the numerator by the reciprocal of the denominator.

$\frac{425}{9} \times \frac{9}{85}$

$5$

Help me please, kinda lost

Dmitry_Shevchenko [17]

Answer:

400cm^2

Step-by-step explanation:

For this question, you need to find the surface areas of both objects, then add them together.

For the cube:

56cm for the front

56cm for the back

42cm for the side

42cm for the other side

48cm for the top

48cm for the bottom

SA for the cube: 292cm^2

For the triangle, things are a little different. We do the same process that we did to find the SA of the cube, but we do not have to find the SA of the top side (because there isn't a top side) and we have to divide the total SA by 2 because it's a triangle.

For the triangle:

42cm for the front

42cm for the back

54cm for the slanted side

42cm for the other side

36cm for the bottom

SA for the triangle: (216/2)^2=108cm^2

292+108=400cm^2

the SA of the composite figure is 400cm^2

WILL GIVE BRAINLIEST AND 20 POINTS

MrRissso [65]

Answer:

14 yd²

Step-by-step explanation:

4 • 7 = 28

Since this is a triangle you divide the answer by 2

28/2 = 14

14 yd²

Triangle ABC is a right triangle. The sides measure AB = 3 and BC = 4. Use the Pythagorean theorem to find CA. A. CA = 25 B. CA

Vesna [10]

Answer:

CA = 5

Step-by-step explanation:

Since the sides are 3 and 4, we recognize this as a 3:4:5 right triangle, with CA = 5. Using the Pythagorean theorem confirms this:

CA² = AB² +BC²

CA² = 3² +4² = 9 +16 = 25

CA = √25

CA = 5

Help I'm not sure if this is the answer?<br><br> (This question is about trigonometric ratios)

Answer:

(b) 15.32

Step-by-step explanation:

You can use your triangle sense to answer this.

The side x will always be shorter than the hypotenuse, 20. This eliminates the last two choices.

If the angle is 45°, then the sides are equal at about 0.707 times the length of the hypotenuse. That would make them 0.707×20 = 14.14. Since the angle is greater than 45°, the opposite side will be greater than 14.14. Only one answer choice fits between 14 and 20: the second choice -- 15.32.

The mnemonic SOH CAH TOA reminds you of the relation ...

Sin = Opposite/Hypotenuse

sin(50°) = x/20

x = 20×sin(50°) . . . . multiply by 20 to find x

x ≈ 15.32 . . . . . . . . . use your calculator to evaluate

The attachment is intended to show how the triangle side lengths change with angle.
