Mallory bought pizza and soda for her End of Summer party. If she spent $12.57 on the
sodas and $10.95 for each pizza, how many pizzas did she buy if she spent $89.22?
Which equation models this scenario?
12.57 + 10.95 = 89.22
10.95x + 12.57 =
89.22
12.57x + 10.95 =
89.22
89.22x - 10.95 = 12.57
Answer:
10.95x + 12.57 = 89.22

What is the measure of angle DFE?
Answer:
28
Step-by-step explanation:
its vertically opposite
Answer:
28
Step-by-step explanation:
Vertical angles always have the same measure, so the measure of DFE would also be 28 degrees
f(x)=x^2+3x-5. find and simplify f(x+h)-f(x)
Answer:
[tex]f(x + h) - f(x) = h^2 + 3h - 5[/tex]
Step-by-step explanation:
Given
[tex]f(x) = x^2 + 3x - 5[/tex]
Required
Find f(x + h) - f(x)
In functions:
[tex]f(x + h) = f(x) + f(h)[/tex]
So:
[tex]f(x + h) - f(x) = f(x) + f(h) - f(x)[/tex]
Collect Like Terms
[tex]f(x + h) - f(x) = f(x) - f(x)+ f(h)[/tex]
[tex]f(x + h) - f(x) = f(h)[/tex]
Solving for f(h)
[tex]f(h) = h^2 + 3h - 5[/tex]
So:
[tex]f(x + h) - f(x) = h^2 + 3h - 5[/tex]
Need help for Geometry
Given :
segment AB = segment DEsegment BC = segment EFsegment AC = segment DFSince all sides are equal triangle ABC is congruent to triangle DEF under the SSS congruence criterion.
m∠B = (92+y)°
m∠E = (6y-28)°
We know that :
angle B = angle EWhich means :
[tex] = \tt92 + y = 6y - 28[/tex]
[tex] =\tt 92 = 6y - 28 - y[/tex]
[tex] =\tt 92 = 5y - 28[/tex]
[tex] = \tt92 + 28 = 5y[/tex]
[tex] = \tt120 = 5y[/tex]
[tex] =\tt y = \frac{120}{5} [/tex]
[tex] =\tt y = 24[/tex]
Thus, the value of y = 24
Then :
angle B :
[tex] =\tt 92 + y[/tex]
[tex] =\tt 92 + 24[/tex]
[tex] = \tt116[/tex]
Thus, the measure of angle B = 116
angle E :
[tex] = \tt6y - 28[/tex]
[tex] =\tt 6 \times 24 - 28[/tex]
[tex] =\tt 144 - 28[/tex]
[tex] =\tt 116[/tex]
Thus, the measure of angle E = 116
Since the measure of both these angles is equal we can conclude that we have found out their correct measures.
measure of segment AC = 2x + 47
Measure of segment DF = 6x + 3
Segment AC = Segment EFWhich means :
[tex] = \tt6x + 3 = 2x + 47[/tex]
[tex] = \tt6x + 3 - 2x = 47[/tex]
[tex] = \tt4x + 3 = 47[/tex]
[tex] \tt4x = 47 - 3 \\ 4x = 44[/tex]
[tex] =\tt x = \frac{44}{4} [/tex]
[tex] =\tt x = 11[/tex]
Thus, the value of x = 11
Let us check whether or not we have found out the correct value of x by placing 11 in the place of x :
[tex] = \tt6 \times 11 + 3 = 11 \times 2 + 47[/tex]
[tex] =\tt 66 + 3 = 22 + 47[/tex]
[tex] =\tt 69 = 69[/tex]
m∠B = 69°m∠C = 69°Therefore, the value of x = 11There are 2 white chocolates for every plain chocolate in a box of chocolates.
There are no chocolates of any other colour in the box.
There are 10 plain chocolates in the box.
How many chocolates are there in the box altogether?
Answer:
The are 30 chocolates in the box.
Step-by-step explanation:
Since there are 2 white chocolates for every plain chocolate in a box of chocolates, and there are no chocolates of any other color in the box, and there are 10 plain chocolates in the box, to determine how many chocolates are there in the box altogether the following calculation must be performed:
10 + (2 x 10) + 0 = X
10 + 20 + 0 = X
30 = X
Therefore, there are 30 chocolates in the box.
2.2 Roulette wheel: The game of roulette involves spinning a wheel with 38 slots: 18 red, 18 black, and 2 green. A ball is spun onto the wheel and will eventually land in a slot, where each slot has an equal chance of capturing the ball. a) You watch a roulette wheel spin 4 consecutive times and the ball lands on a red slot each time. What is the probability that the ball will land on a red slot on the next spin
Answer:
9/19
Step-by-step explanation:
Number of slots =38
red balls R = 38, black balls B = 18, green balls G = 2
we want to calculate
P( Red ball/ previous 4 spins are red) = P( red ball) [because each spin is independent to other]
= 18/38 = 9/19

Explanation:
Focus on triangle TRS. This triangle has congruent base angles as shown by the double arcs. This means that the sides opposite these angles (TR and RS) are congruent. So TR = RS.
Because RS = 11, this makes TR = 11 too.
Now move onto triangle UTR. This triangle is equilateral because each angle is the same measure (each angle being 60 degrees).
So UT and TR are the same length, and,
UT = TR
x-7 = 11
x-7+7 = 11+7
x = 18
--------------
Since every angle of triangle UTR is 60 degrees, this makes angle URT 60 degrees and angle TRS to be 180-60 = 120 degrees.
Move back to triangle TRS. We have these interior angles:
R = 120T = 5yS = 5yFor any triangle, the interior angles always add to 180
R+T+S = 180
120+5y+5y = 180
10y+120 = 180
10y = 180-120
10y = 60
y = 60/10
y = 6
cuales son los angulos de 125
[tex] [/tex]
Answer:
Ángulo de 125 grados Cómo se llama
Este ángulo es obtuso porque 120 es un número mayor que 90 y menor que 180. Es decir, la amplitud de este ángulo mide entre los 90º y los 180º: 90º < 120º < 180º.

A factory produce bicycles at a rate of 110+0.5t^2-0.9t bicycles per week (t in weeks)
how many bicycles were produced from 8 to 2
Answer:
221
Step-by-step explanation:
Day 8 is the first day of the second week.
Day 21 is the last day of week 3.
We need to know the n umber of bicycles made from t = 1 to t = 3
The function is b(t) = 110 + 0.5t^2 - 0.9t, where t is in weeks.
We need to integrate the function with the limits of 1 to 3.
[tex] \int_{1}^{3} (110 + 0.5t^2 - 0.9t) dt [/tex]
[tex] \int_{1}^{3} (110 + \dfrac{t^2}{2} - \dfrac{9t}{10}) dt [/tex]

what is the reciprocal of 19
Answer:
1/19
Step-by-step explanation:
In order to find the reciprocal of a number, we need to flop it over.
"Flopping over" is not the same as "changing the sign of the number"
So what does "flopping over" actually mean?
Consult the following formula:-
[tex]\sf{The~reciprocal~of~a~is\mapsto\frac{1}{a} }[/tex]
According to the formula,
[tex]\sf{The~reciprocal~of~19~is~\frac{1}{19}}[/tex]

HELP ME PLEASEEEEE THIS IS SO HARD
Answer:
4. Given
6. Definition of verticle angles
7. Algebra/part-whole-postulate/sum of interior angles in a triangle/CPTCTC (Corresponding parts of congruent triangles are congruent)
Step-by-step explanation:
number 4 is just...given because it shows that they're both right angles
6, it's literally the definition of verticle angles
7, since we know that angle TQU and angle RSU are congruent and angle QUT and SUR are congruent, if we subtract those from 180, that means those two angles also have to be congruent
Also, the two triangles are congruent by LA or ASA, so CPCTC would also work
Part-whole-postulate, same reasoning as algebra.
Sum of interior angles in a triangle, same as algebra.
Hope this helped, let me know if you have any questions.
