Answer:

Step-by-step explanation:

Given the the height covered by the ball modeled by the equation

y= -4.9x²+12

Since we are not told what to find, we can as well find the time taken by the ball to reach the ground.

The ball hits the ground when y = 0. Substitute y = 0 into the equation and calculate x;

y= -4.9x²+12

0 = -4.9x²+12

Subtract 12 from both sides

0-12 = -4.9x²+12-12

-12 = 4.9x²

x² = -12/4.9

x² = 2.448

x = √2.448

x = 1.57s

Hence we can say that the ball hits the ground after 1.57s.

to the nearest whole number it is 16877

Step-by-step explanation:

since 5-9 are rounded up

Answer: Area of tank = lbh

                                    = 6 x 4.3 x 3.5

                                    = 90.3 m^3

1 liter = 1000cm^3

90.3m^3 = 90300 cm^3

90.3l

Answer: PN= 20 in.

Step-by-step explanation:

Given: In triangles PMN and QSR :

Length of P N ≅ Length of RQ  (1)    [ '≅' → Sign of congruence]

Length of QS ≅ Length of PM

Length of MN ≅ Length of RS

By SSS congruence rule

ΔPMN ≅ ΔQSR

Since Length of QR =20 in. [Given]

From (1)

Length of PN= 20 in.  [Congruent means exactly equal]

Answer:

there is no unit rate but hers an example of an unit rate using 5.76 NOT THE ANSWER

Step-by-step explanation:

Example: 64 ounces of water in a bottle that costs $5.76. To find the unit rate per ounce, divide the amount it costs ($5.76) by the number of ounces (64). $5.76 ÷ 64 ounces = $0.09 per ounce

Answer:

11 cars

Step-by-step explanation:

If he earned 70 cars 7 that means he earned 10 dollars per car. So in order to make 110 dollars he must wash 11 cars.

Answer:

11 cars

Step-by-step explanation:

$70total/7 cars= $10 per car

$110 total/$10 per car= 11 cars

Answer:

a)E=.05t +34

b)$54

c)$600

Step-by-step explanation:

a) he gets 5% of tips out of all tips people gave to the restaurant , 5% --> .05 (as a decimal) --> this is "t"

he earns an extra $34 a night of work. --> this is the constant

E= --> the total earned that night

E=.05t +34

b) simply plug in the total tip into the equation

E=.05(400) + 34

E=$54

--> he earned $54 that night

c) since we are given the total earned that night, we now plug in for y. in this case we plug "$64" for y

we find t, which is tip the restaurant was given

--> 64 = .05t +34

-34. -34

30= .05t ---> divide by .05 each side

t= $600

the restaurant was tiped 600 dollars and Alun was paid 64 dollars that night of work

Answer:

8 meters per second or 8/1

Step-by-step explanation:

Divide 400 meters by 50

8

So it is 8 meters per second

Hope this helps :)

Please consider Brainliest :)

Answer:

8 meters per 1 second

Step-by-step explanation:

first, do 400m/50sec

then, do 400m/1 divided by 50sec/1

next, do keep change flip so, 400/1 * 1/50=400/50

last simplify so, 400 divided by 50 and 50 divided by 50 equals 8/1

Answer:

D

Step-by-step explanation:

9.5 times the sum means you'd have to the addition first but the equation should but the same as the words. Order of operations states to do the parenthesis first. Therefore, the answer is D (10+5/4)x9.5

Answer:

A.

Step-by-step explanation:

If it's 9.5 times the sum of 10 and 5/4, the answer is A.

Its not b because its called 10 plus 9.5 times 5/4.

Its not c because it is called 9.5 PLUS the sum of 10 and 5/4.

Its not d because its called 10 plus 9.5 times 5/4.

Therefore, the word version fits with answer a.

Answer:

b

Step-by-step explanation:

To evaluate g(h(- 2)), evaluate h(- 2), then use the value obtained to evaluate g(x), that is

h(- 2) = x + 4 = - 2 + 4 = 2, then

g(2) = 5x = 5(2) = 10 → b

Answer: It’ll be 8/35

Answer:

See Explanation

Step-by-step explanation:

3.

XY is tangent at P and CP is radius

[tex] \therefore CP\perp XP\\(\because tangent\: is \: perpendicular \: to\: radius) \\\\

\therefore m\angle CPX = 90\degree \\[/tex]

4.

Radius of the circle = diameter /2 = 13/2 = 6.5.cm

5.

For BD to be be tangent to the circle with center C, BD should make right angle with radius CB.

[tex] AD^2 [/tex] should be equal to the sum of the squares BD and AB.

Let us work it out:

[tex] AD^2 = 7^2 = 49....(1)\\

AB^2 + BD^2 = 5^2 +5^2 \\

AB^2 + BD^2 = 25 + 25 \\

AB^2 + BD^2 = 50....(2) \\[/tex]

From equations (1) & (2), it is obvious that:

[tex] AD^2 \neq AB^2 + BD^2[/tex]

So, BD is not tangent to the[tex] \odot\: C. [/tex]

6.

Tangents drawn from an external point to a circle are congruent.

In circle with center C, BA and BD are tangents drawn from external point B.

Therefore,

BA = BD

x = 4

7.

In circle with center C, BA and BD are tangents drawn from external point B.

Therefore,

BD = BA (tangents drawn from external point to a circle)

x = 2

8.

In circle with center C, BA and BD are tangents drawn from external point B.

Therefore,

BA = BD (tangents drawn from external point to a circle)

2x = 10

x = 10/2

Answer:

1

Step-by-step explanation:

To evaluate, substitute x = - [tex]\frac{2}{3}[/tex] into f(x), that is

f(- [tex]\frac{2}{3}[/tex] )

= 3(- [tex]\frac{2}{3}[/tex] )² + 2(- [tex]\frac{2}{3}[/tex] ) + 1

= 3([tex]\frac{4}{9}[/tex] ) - [tex]\frac{4}{3}[/tex] + 1

= [tex]\frac{4}{3}[/tex] - [tex]\frac{4}{3}[/tex] + 1

= 0 + 1

= 1

Answer:

1

Step-by-step explanation:

f(x) = 3x² + 2x + 1

f(-2/3) = 3x² + 2x +1

f(-2/3) = 3(-2/3)² + 2(-2/3) + 1          

Substitute the value in for all the x's

f(-2/3) = 3(4/9) + 2(-2/3) + 1

f(-2/3) = 12/9 + (-4/3) + 1

f(-2/3) = 4/3 + (-4/3) + 1                

Subtracting 4/3 by (-4/3) gets you 0 so I didn't write it down.

f(-2/3) = 1

So, the answer I got is 1

Answer:

3/4

Step-by-step explanation:

Find where the line intercepts perfectly and you will see you it goes up 3 and to the left 4 so the slope is 3/4

Answer: 83

Step-by-step explanation: Because the triangles are congruent, angle A is congruent to angle D, angle C is congruent to angle F, and angle E is congruent to angle B (CPCTC). Now because angle A and D are congruent they are both equal to 50. Using sum of angles in a triangle, you can find that measure of angle E is equal to 180- (47+50). That is 180-97=83.

Answer:

∠ E = 83°

Step-by-step explanation:

Since the triangles are congruent then corresponding angles are congruent.

Thus ∠ C = ∠ F = 47° and

∠ B = 180° - (50 + 47)° ← angle sum of Δ

∠ B = 180° - 97° = 83°

∠ B and ∠ E are corresponding angles, thus

∠ E = ∠ B = 83°

Step-by-step explanation:

a=p

base=10

height=x

area=10 times x

perimeter=10+10+x+x

to work out area you times the base (10) by the height however since the height is x in this instant the answer is 10 times x which simplifies to 10x
