Answer:
9 cupcakes on Saturday
Step-by-step explanation:
(p + 3) more than p is p + p + 3 = 2p + 3
on Saturday she baked p
on Sunday she baked 2p + 3 , then
p + 2p + 3 = 30
3p + 3 = 30 ( subtract 3 from both sides )
3p = 27 ( divide both sides by 3 )
p = 9
She baked 9 on Saturday and 21 on Sunday

What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
In the given figure
AC = CB , DA = EB and ∠A = ∠B
So,
ΔACD ≅ ΔBCE
Now corresponding sides of a congruent triangle are the same.
So,

Prove: ∠K P L ≅ ∠ M R L
∠KPL ≅ ∠MRL as perpendicular always makes an angle of 90°.
What specifically is meant by "triangle congruency"?When two triangles' three corresponding sides and angles are the same sizes, they are said to be congruent.These triangles can be moved, rotated, flipped, and turned to look exactly the same.They will coincide if they are moved.Congruence exists when two triangles satisfy the five congruence conditions.They are the side-side-side (SSS), the side-angle-side (SAS), the angle-side-angle (ASA), the angle-angle-side (AAS), and the right angle-hypotenuse-side (RHS).So,
Given: ∠ K ≅ ∠M, KP⊥ PR, MR ⊥ PR
To Prove: ∠KPL ≅ ∠MRL
As MR ⊥ PR (Given), then: ∠MRL = 90°Similarly, KP⊥ PR (Given), then: ∠KPL = 90°So, ∠KPL ≅ ∠MRL.

Extended ratios can be used to compare three or more quantities.
Given statement 'Extended ratios can be used to compare three or more quantities.' is True.
We know that an extended ratios are ratios that compare more than two quantities.
If we're comparing values x, y and z, then we would express this using the extended ratio x : y : z.
For example, suppose a triangle has side lengths of 15, 45, and 10.
The extended ratio that compares the side lengths of the triangle is:
15 : 45 : 10
We can simplify this ratio by factoring each of 15, 45, and 10 and cancelling out any factors that are common to all three quantities.
(5 × 3) : (5 × 9) : (5 × 2)
5 is a common factor of all three quantities, so cancel it out.

two companies sell custom t shirts company a charges $5 per shirt plus a one time $20 service fee company b charges $7 per shirt plus a one time $10 service fee what is the number of shirts were both companies would cost the same
The number of shirts produced by each company to have the same cost are 5 shirts.
We have that:
For Company A:
Fixed cost will be = $ 20
Cost per shirt = $ 5
For company B:
Fixed cost will be = $ 10
Cost per shirt = $ 7
Let the number of shirts be x.
Equation for cost for company A:
Cost = 20 + 5 x
Equation for cost for company B:
Cost = 10 + 7 x
Now, put both the companies cost equal, we get that:
10 + 7 x = 20 + 5 x
7 x - 5 x = 20 - 10
2 x = 10
x = 10 / 2
x = 5
Therefore, the number of shirts produced by each company to have the same cost are 5 shirts.

Ava had a greater percentage of change because her allowance increased by 150%, while Joey's only increased by 133%
Step-by-step explanation:
To find the percentage of change, you'll divide.
For Ava:
18 ÷ 12 = 1.5
This means her percentage of change is 150%
For Joey:
24 ÷ 18 = 1.33333... (Round to 1.33)
This means his percentage of change is 133%
150% > 133%, so Ava has the greater percentage of change.

Answer:
To multiply radicals with different indices, we need to find a common denominator, which is the lowest common multiple (LCM) between the roots. Once we obtain the LCM, we can multiply each root and exponent in the radicand to obtain the LCM, and rewrite as one radical
When we multiply two radicals with the same type of root (both square roots, both cube roots, and so on), we simply multiply the radicands (the expressions under the radical signs) and put the product under a radical sign

At an amusement park, 360 visitors rode the roller coaster in 3 hours. Write and solve a proportion to find the number of visitors at this rate who will ride the roller coaster in 7 hours.
Answer:
840
Step-by-step explanation:
360 divided by 3 = 120 Visitors per Hour
Now you do you 120 x 7 which equals to 840
Hope this helps ^^
Step-by-step explanation:
360 visitors in 3 hours.
that gives us the ratio
360/3
and because a ratio is nothing else than a fraction with a special meaning, we cab simplify this like any other fraction too :
360/3 = 120/1 = 120
in other words, out of the 3-hour ratio we know that there are 120 visitors in 1 hour.
and now it is easy to use it to find the number of visitors for 7 hours.
remember, if we multiply one part of the fraction by something, we need to multiply also the other part by the same number so that the value of the fraction stays the same.
in other words, we can only do
a/b × c/c
so, if we multiply the bottom part of our ratio by 7 (to go to 7 hours), we also have to multiply the top part by 7 to keep the ratio :
120/1 × 7/7 = 840/7
that tells us that there are 840 visitors in 7 hours.

Write an equation of each line in standard form with integer coefficients.
the line through (1,2) with slope 4/5
The equation of the line in standard form passing through point (1 , 2) with slope equal to 4/5 is 4x - 5y = -6.
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Using the point slope form, plug in the values of the slope and the point to set up the equation.
(y - y1) = m(x - x1)
where m = 4/5 and (x1 , y1) = (1 , 2)
(y - 2) = 4/5(x - 1)
y - 2 = 4/5 x - 4/5
To express it in standard form, arrange the variables in one side and the constants on the other.
y - 2 = 4/5 x - 4/5
4/5 x - y = -2 + 4/5
4/5 x - y = -6/5
Multiply both sides by 5 to have integer coefficients.

Marvel consists of calcium, carbon, and oxygen in the ratio 10:3:12
a) How much carbon would you find in a 300kg piece of marvel?
b) what percentage of marble is calcium
How do I work with these ratios I'm confused
Using proportions, it is found that:
a) You would find 36 kg of carbon is a 300 kg piece of marvel.
b) 40% of marble is Calcium.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For this problem, the ratio 10:3:12 of calcium, carbon and oxygen means that:
Calcium is 10/25 of the total.Carbon is 3/25 of the total.Oxygen is 12/25 of the total.Hence for item a, the amount is given as follows:
300 x 3/25 = 36.
You would find 36 kg of carbon is a 300 kg piece of marvel.
For item b, the percentage is found as follows:
