Answer:

B

Step-by-step explanation:

B, because -9.2 = -4.5, which is less than -4.12. Also, 17/4 = 4.25 is less than sqrt(20), which is 4.4721

Answer:

6

Step-by-step explanation:

[tex]\triangle{PQR}[/tex] is a right triangle.  Use the Pythagorean Theorem:

(leg)^2 + (leg)^2 = (hypotenuse)^2

The length of PR is r + 4; it's the hypotenuse.

[tex]PQ^2+QR^2=PR^2[/tex]

[tex]r^2+8^2=(r+4)^2 \\ r^2+64=r^2+8r+16 \\ 64=8r+16 \\ 48=8r \\ 6=r[/tex]

Remember, to expand [tex](r+4)^2[/tex] you multiply [tex](r+4)(r+4)[/tex]

Answer:

17 + m ≤ 65

Step-by-step explanation:

Maximum distance = 65 miles

Number of miles already ridden = 17

Expression to represent how many more miles, 'm' she can ride ;

Number of miles already ridden + m ≤ maximum distance

17 + m ≤ 65

m ≤ 65 - 17

m ≤ 48

The amount of additional miles Lyla can ride is at most 48 miles

no

Step-by-step explanation:

to be a right triangle, the squared of the base and height must equal the hypotenuse squared:

[tex]\sqrt{\left(3.45^2\right)+\left(9.75^2\right)}[/tex]= 10.34238

10.24^2 =/= 10.34

Answer:

A) -18 B) r=10 C) x=-4

Step-by-step explanation:

A) 1d + 12 = 14-20

Step 1: Simplify both sides of the equation.

1d+12=14−20

d+12=14+−20

d+12=(14+−20)(Combine Like Terms)

d+12=−6

d+12=−6

Step 2: Subtract 12 from both sides.

d+12−12=−6−12

d=−18

Answer:

d=−18

B) 4(20+5) = 10r

Step 1: Simplify both sides of the equation.

100=10r

Step 2: Flip the equation.

10r=100

Step 3: Divide both sides by 10.      

r=10

C) -2(5 + x) - 1 = 3(x + 3)

Step 1: Simplify both sides of the equation.

−2(5+x)−1=3(x+3)

(−2)(5)+(−2)(x)+−1=(3)(x)+(3)(3)(Distribute)

−10+−2x+−1=3x+9

(−2x)+(−10+−1)=3x+9(Combine Like Terms)

−2x+−11=3x+9

−2x−11=3x+9

Step 2: Subtract 3x from both sides.

−2x−11−3x=3x+9−3x

−5x−11=9

Step 3: Add 11 to both sides.

−5x−11+11=9+11

−5x=20

Step 4: Divide both sides by -5.

x=−4

Answer:

A  a.  25 minutes

Step-by-step explanation:

Let x = time in minutes.

Aquarium I contains y water at time x.

y = 4.6 + 1.2x

Aquarium II contains y water at time x,

y = 54.6 - 0.8x

We want the amounts of water to be equal, so we set the right parts of the equations equal and solve for x, the time in minutes.

4.6 + 1.2x = 54.6 - 0.8x

Subtract 4.6 from both sides.

Add 0.8x to both sides.

2x = 50

Divide both sides by 2.

x = 25

Answer:

D

Step-by-step explanation:

"Parallel" means the lines have the same slope- the fractions need to be equivalent. This almost means if it's negative, like in this case, the slope must be negative. 4/6 is equal to 2/3 and is negative like the one shown.

Answer:

Interest = $ 90000

Step-by-step explanation:

Given, Principal= $15000

Rate = 3%

Time = 5 years

Interest = P × R × T/100

Therefore, Interest = 15000 × 3 × 5/100

(dividing 100 by 5 to get 20)

= 15000 × 3 × 20

= 90000

Answer:

b option

x<-4 is the correct answer

Answer:

Hello. It does have a maximum and minimum. You would have to use the formula x=-b/2a to find both of them. So first you have the equation which is x=2(x-2)^2+3, which you would have to make it an equation which is equals to F(x)=2x^2-8x+11. So b would be 8 and a would be 2. Enter them into the formula. So the answers would be (2,3)

Step-by-step explanation:

Answer:

b) Find the measurements of a rectangk with a perimeter of

26cm and an area of 1600cm​

There is no way to get an area of 1600 cm using a perimeter as small as 26 cm.

Step-by-step explanation:

perimeter = 2(L + W) = 26, then L + W = 13, so L = 13 - W

area = L x W = 1600

substitute for L:

(13 - W)W = 1600

13W - W² = 1600

-W² + 13W = 1600

-W² + 13W - 1600 = 0

W² - 13W + 1600 = 0

Answer:

33.75 ft

Add up every time it travels both up and down.

12 + 6 + 6 + 3 + 3 + 1.5 + 1.5 + .75 = 33.75 on the fourth landing.

Step-by-step explanation:

The ball traveled a total of 12 feet vertically when it hit the ground for the fourth time.

The length along a line or line segment between two points on the line or line segment.

The ball is dropped from a height of 12 feet, so we can represent this with the point (0,12) on a coordinate plane.

The ball then bounces up to a height of 6 feet (half the height of the previous bounce), so we can represent this with the point (1,6) on the coordinate plane.

The ball then bounces down to a height of 3 feet (half the height of the previous bounce), so we can represent this with the point (2,3) on the coordinate plane.

The ball then bounces up to a height of 1.5 feet (half the height of the previous bounce), so we can represent this with the point (3,1.5) on the coordinate plane.

The ball then hits the ground for the fourth time.

The distance of the first bounce is 12 - 6 = 6 feet.

The distance of the second bounce is 6 - 3 = 3 feet.

The distance of the third bounce is 3 - 1.5 = 1.5 feet.

The distance of the fourth bounce is 1.5 - 0 = 1.5 feet

The total distance the ball traveled vertically is: 6 + 3 + 1.5 + 1.5 = 12 feet

Hence, the ball traveled a total of 12 feet vertically when it hit the ground for the fourth time.

Answer:

x = -1.135 (approx).

Step-by-step explanation:

x^3 = ∛(x - 2)

Cube both sides:

x^9 = x - 2

Subtract x and add 2 to both sides:

x^9 - x + 2 = 0

We could solve this for real roots by drawing a graph.

I did this and got one root  x = -1.135 (approx).

The other 8 roots are complex.

Answer:

See solution below

Step-by-step explanation:

According to pythagoras theorem

hyp^2 = opp^2 + adj^2

10^2 = 4^2 + b^2

100 = 16 + b^2

b^2 = 100-16

b^2 = 84

b = √84

b ≈ 9

Using SOH CHA TOA identity

sin B = AC/AB

Sin B = 9/10

B = arcsin0.9

B ≈ 64degrees

sinA = BC/AB

Sin A = 4/10

A = arcsin0.4

A ≈ 24degrees
