There is a group of 10 people who are ordering pizza. If each person gets 2 slices and each pizza has 4 slices, how many pizzas should they order?
Answer:
5 pizzas
Step-by-step explanation: If you have 10 people and each will get two slices then you will need 20 pieces of pizza because 10x2 is 20. If each pizza has 4 slices then you will need 5 pizzas because 4/20 is 5.
Answer:
5 pizzas.
Step-by-step explanation:
Find out how many slices the group of 10 people need in total:
2 x 10 = 20 slices
Now, use the total number of slices and divide it with 4 to find how many pizzas they need.
20 ÷ 4 = 5
They need 5 pizzas for 10 people who each get 2 slices.
7. If 294 J of heat is transferred to a 10.0 g sample of silver at 25 ºC, what is the
final temperature of the silver? Specific heat capacity of silver is 0.235 J/gºC.
Answer:
T~final is 150.11 C
Step-by-step explanation:
To solve this we need this specific heat equation:
Q=mc(T~final - T~initial) that is the difference of final temperature minus initial temperature.
We are given:
Q = 294 J
m = 10 g
c = 0.235 J/gC
T~initial = 25 C
Plug the values in to the equation
294 J = 10 g * 0.235 J/gC * T(difference)
294 J = 2.35 J/C * T(difference)
Divide both sides by 2.35 J/C
294 J / 2.35 J/C = T(difference)
T(difference) = 125.11 C
If the initial temperature was 25 C then then
T~final = 25 C + 125.11 C or 150.11 C

Find the slope of the line y = 5/8x - 1/2
Answer:
slope = [tex]\frac{5}{8}[/tex]
Step-by-step explanation:
Slope-intercept form is the way in which an equation is written to easily identify the line's slope and y-intercept. It is represented by the equation y = mx + b, in which m represents the slope.
By looking at the equation, we can see that it takes the y = mx + b format - y is isolated - therefore it is in slope-intercept form. Remember that the number in place of the m would represent the slope - and in this case, that number is [tex]\frac{5}{8}[/tex].
Final Answer:
[tex]\sf{Slope = \dfrac{5}{8}}\\\sf{Y-intercept: -\dfrac{1}{2}}[/tex]
In-depth explanation:
The question is asking us to find the slope of the line, whose equation is;
[tex]\leadsto\quad\bf{y=\dfrac{5}{8}x-\dfrac{1}{2}}[/tex]
The format of this equation is: [tex]\boldsymbol{\sf{y=mx+b}}[/tex]. This is known as slope-intercept; it's the most common way of writing the equation of a line.
In y = mx + b, the variable "m" denotes the slope, or the rate of change, of a line; b denotes the y-intercept, or the point where the line intercepts the y-axis.
Also, the slope is the number before x, while b is the constant term.
Similarly, the slope is 5/8 and the y-intercept is -1/2.

a) Work out the value of G
give your answer in standard form correct to 3 significant figures
b) Work out the new value of G
give your answer in standard form correct to 3 significant figures
Answer:
a. G = 4590.0
b. G = 4550.0
Step-by-step explanation:
Given that: G = [tex]\sqrt{\frac{m}{t^{2} } }[/tex]
a. m = 6.1 x [tex]10^{-5}[/tex] and t = 1.7 x [tex]10^{-6}[/tex]
Thus,
G = [tex]\sqrt{\frac{6.1*10^{-5} }{(1.7*10^{-6}) ^{2} } }[/tex]
= [tex]\sqrt{\frac{6.1*10^{-5}}{2.89*10^{-12} } }[/tex]
= [tex]\sqrt{21107266.44}[/tex]
G = 4594.26452
G = 4590.0
b. m = 6.1 x [tex]10^{-5}[/tex] + ( 6.1 x [tex]10^{-5}[/tex] x 0.08)
= 6.588 x [tex]10^{-5}[/tex]
t = 1.7 x [tex]10^{-6}[/tex] + (1.7 x [tex]10^{-6}[/tex] x 0.05)
= 1.785 x [tex]10^{-6}[/tex]
So that,
G = [tex]\sqrt{\frac{6.588*10^{-5} }{(1.785*10^{-6}) ^{2} } }[/tex]
= [tex]\sqrt{\frac{6.588*10^{-5} }{3.186*10^{-12} } }[/tex]
= [tex]\sqrt{20676505.9}[/tex]
G = 4547.1426
G = 4550.0

Mariah bought 5 shirts that each cost the same amount and a pair of jeans that cost $30. She spent a total of $150 at the store. Write an equation to determine the cost of each shirt.
Answer:
150-30=5x
Step-by-step explanation:
If the total is $150 and a pair of jeans is $30, then you'd subtract them. Since you have to find out how much each shirt is, you'd put 5x on the other side of the equal sign. Then solve for X.
Hope this helps!

What is the measure of the angle in red?
Answer:
B
Step-by-step explanation:
The red line is almost 360 degrees.
If you subtract 65 from 360 you get 295
When two straight lines or rays intersect at a shared endpoint, an angle is generated. The measure of the angle in red is 295°. The correct option is B.
What is an angle?When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
The total angle at a point is always equal to 360°. Given that the measure of the green angle is 65°.
But as it can be seen that the red angle and the green angle together form a complete rotation of 360°. Therefore, the sum of the two angles can be written as,
Red angle + Green angle = 360°
Red angle + 65° = 360°
Red angle = 360° - 65°
Red angle = 295°
Hence, the measure of the angle in red is 295°.

D. John's boat was farther and faster
Step-by-step explanation:
The equation tells you that at x = 0, Roberta's boat was 10 miles from the dock. The words tell you John's boat started 20 miles from the dock, so his boat started farther away.
John's boat traveled a distance of (55 -20) = 35 miles in 5 hours, so the speed was (35 mi)/(5 h) = 7 mi/h. The equation tells you Roberta's boat traveled 6 miles for each hour, so John's boat was faster.
John's boat was farther and traveled more quickly
__
Additional comment
The variables in Roberta's equation are not defined. In order for the problem to make sense, we must assume that x represents time in hours, and y represents distance in miles.

hi
Please help!!! I’ll give brainiest
Answer:
Parker is NOT right when he says that it is a division problem 6 ÷ 3.
In fact, it is a multiplication problem 6 × 3 because 6 × 3 = 18 would give us the correct number of total rectangles which are 18
Step-by-step explanation:
Total number of rectangles = 18
As there are 3 rows with each row containing 6 rectangles.
Now, if we multiply 6 with 3, we get the result 18.
Thus,
6 × 3 = 18
Hence, Parker must have mentioned that this arrow of 18 rectangles shows the multiplication problem 6 × 3.
Thus,
Parker is NOT right when he says that it is a division problem 6 ÷ 3.
In fact, it is a multiplication problem 6 × 3 as 6 × 3 = 18 would give us the correct number of total rectangles which are 18.
