Answer:

3/8 of the pizza is left

Step-by-step explanation:

say the pizza was cut into 8 slices. Justin at 1/4 of the pizza, we can also put that as 2/8. so now 2 slices are gone. that leaves us with 6 slices. Dan ate 3/8 so now 3 more slices are gone. now we only have 3 left. since we started out with 8 we'll use that as a denominator; 3/8. or look at the image attached

Answer:

x = 12

Step-by-step explanation:

Given:

m<BCF = 4x°

m<CFE = 11x°

Required:

m<BCF and m<CFE

SOLUTION:

m<BCF + m<CFE = 180° (same side interior angles are supplementary)

Substitute

4x + 11x = 180

15x = 180

Divide both sides ny 15

15x/15 = 180/15

x = 12

Answer:

2r + 3s= 9 <=> -6r -9s = -27;

3r + 2s= 12 <=> 6r + 4s = 24;

                   => 0*r -5*s = -3 => s = 3/5;

2*r + 3*(3/5) = 9<=> 10*r + 9 = 45 <=> 10*r = 36 => r = 18/5;

Mr. Reed DATA:

rate = 40 mph ; time = x 4.5 hrs ; distance = 40x miles

-----

Mrs. Reed DATA:

rate = 60 mph ; time = x hrs ; distance = 60x - 210 miles

------

Equation:

40x = 60x -210

-20x = -210

x = 10.5 hrs

x-3.5 = 7 hrs (Mr. Reed's time)

Answer:

[tex] 18,432\pi \: {in}^{3} [/tex]

Step-by-step explanation:

Base diameter of cylinder = 48 in

So, base radius (r) = 48/2 = 24 in

Height of oil filled in the can (h) = 32 in

Volume of portion of the can that is filled with oil

[tex] = \pi {r}^{2} h \\ \\ = \pi \times (24)^{2} (32) \\ \\ =18,432\pi \: {in}^{3} [/tex]

Answer:

a) The vertex of the graph is [tex](h,k) = (0, 31)[/tex], b) [tex]a = -16[/tex], c) The equation of the parabola is [tex]f(t) = -16\cdot t^{2}+31[/tex].

Step-by-step explanation:

a) The tennis ball experiments a free fall, that is, an uniform accelerated motion due to gravity and in which effects from Earth's rotation and air viscocity are negligible. The height of the ball in time is represented by a second order polynomial. Hence, the vertex of the parabola is the initial point highlighted in graph.

The vertex of the graph is [tex](h,k) = (0, 31)[/tex].

b) If we know that [tex](h,k) = (0, 31)[/tex], [tex]f(t) = a\cdot (t-h)^{2} + k[/tex] and [tex](t,f(t)) = (1,15)[/tex], then the value of [tex]a[/tex] is:

[tex]f(t) = a\cdot (t-h)^{2} + k[/tex]

[tex]15 = a\cdot (1-0)^{2}+31[/tex]

[tex]15 = a\cdot 1 + 31[/tex]

[tex]a = 15-31[/tex]

[tex]a = -16[/tex]

c) The equation of the parabola is [tex]f(t) = -16\cdot t^{2}+31[/tex].

Answer:

The peach will way more then the apple

Hope this helps you ☜(ﾟヮﾟ☜)

The weight of the peach is greater than the weight of apple

In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.

The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.

A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.

Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.

Given data ,

Let the weight of apple be = 85,000 milligrams

And , let the weight of the peach be = 0.15 grams

Now , from the unit conversion

1 gram = 1000 milligrams

And , 1 kilogram = 1000 grams

So , the weight of apple A = 85 grams

And , the weight of the peach P = 150 grams

Therefore , P > A

Hence , weight of peach is larger

Answer:

Step-by-step explanation:

hello :

the sequence is geometric because : (1/4)/(-1/8) = (-1/8)/(1/16)=-2   = r

the nth term is :  An =A1 × r^(n-1)

a common ratio is : r  and A1 the first term

in this exercice :   r =2         A1 = 1/16

when : n =12 you have the  12rd term  A12

A12 = 1/16 × 2^(12-1)  = 1/16 × 2^(11)

Answer:

an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).

Step-by-step explanation:

1.

The obvious question to ask in this situation is, “how many miles does Joseph travel on Mondays”? To compute, we each distance: 3 + 6 + 6 = 15.

Joseph travels 15 miles on Mondays.

3.Perimeter means “distance around a closed figure or shape” and to compute we add each length: 3 + 6 + 6 = 15

4.Solution

Just keep adding those side lengths. 6 + 7 + 4 + 4 + 5 + 6 + 2 = 34 units

If you look closely at the shapes in the previous examples, you might notice some ways to write each perimeter as a more explicit formula. See if the results from what we have done so far match the formulas below.

mary is the 4th childs nam,e

Answer:

x=5

Step-by-step explanation:

The pythagorean theorem stats a^2+b^2=c^2. We are already given the values of the two legs of the triangle so we need to solve for the length of the hypotenuse (the longest part of the triangle). To do so, you put in 3 and 4 as a and b so you get 3^2+4^2=c^2. After squaring both numbers you get 16+9=c^2. Then you add 16 and 9 to get 25=c^2. To get rid of the power of 2, we square root both sides to get rid of the exponent. Since 25 is a perfect square, you get c=5 which means that the x value eqals 5.
