Answer:
50 hours
Step-by-step explanation:
Given that :
Painter can paint 2 small rooms and a balcony on 50 hours
Small room takes twice as long to paint as a balcony
Let :
Time taken to paint balcony = t
Time taken to paint small room = 2t
t + 2(2t) = 50
t + 4t = 50
5t = 50
t = 10
how long will it take him to paint 1 small room plus 3 balconies?
1 small room = 2t
3 balconies = 3t
2t + 3t = 5t
5(10) = 50 hours

11. A line passes through the point (2, 3) and has a slope of 2.
11a. What are the steps you take to find the y-intercept?
11b. What is the equation of the line?
Answer:
11. y=2x-1
11a. you subtract 2 from the y and 1 from the x and draw your points accordingly to go down or you add 2 to the y and add 1 to the x to go up and plot the points accordingly or you could just draw a graph like i did if you dont wanna do it by math lol. :)
11b. oh i guess i already answered this but y=2x-1

What is congruent geometry?In geometry, two figures are congruent if they have the same shape and size, and all their corresponding parts (sides, angles, and vertices) are congruent. Congruent figures can be moved, rotated, or reflected without changing their shape or size.
Here,
To prove that ΔPQS = ΔRQS, we need to show that two pairs of corresponding sides and one pair of corresponding angles are congruent.
Looking at the diagram, we can see that:
PQ = RQ (corresponding sides)
PQ = RQ (common side)
∠PQS = ∠RQS (common angle)
To prove that the two triangles are congruent, we can use the SAS (Side-Angle-Side) postulate, which states that if two pairs of corresponding sides and one pair of corresponding angles are congruent in two triangles, then the triangles are congruent.
Therefore, the answer is (A) SAS.

1. Use at least 2-3 sentences to explain how to find the measure of exterior angle of a triangle if you know the two remote interior angles.
2.Use at least 2-3 sentences to explain how to find the measure of an interior angle of a triangle when you are given the other two angle measures.
Answer:
Step-by-step explanation:
1). By definition of an exterior angle of a triangle,
Measure of exterior angle of a triangle is equal to the sum of opposite two interior angles.
From the figure attached,
m∠4 = m∠1 + m∠2
2). Property of a triangle states that " sum of interior angles of a triangle is 180°"
Therefore, m∠1 + m∠2 + m∠3 = 180°

Is 45m, 36m, 27m a right triangle
Answer:
it is the right triangle
Step-by-step explanation:
A set of three integers that can be the length of the sides of a right triangles
Answer:
Yes
Step-by-step explanation:
This is what I think:
This is because the hypotenuse of the triangle is 45m.
27 ^2 + 36 ^2 = 2025
2025 SQAURE ROOT IS 45.
So the square root of the two other measurements squared must be equal to the hypotenuse.

Devaughn is 13 years younger than Sydney. The sum of their ages is 79 . What is Sydney's age?
Answer: 46 years old
Step-by-step explanation: If Devaughn is 13 years younger than Sydney,
we can represent Sydney's age as x and Devaughn's age as x - 13.
Since the sum of their ages is 79, we have x + x - 13 = 79.
This simplifies to 2x = 92.
Dividing both sides by 2, we have x = 46.
So sydney is 46 years old.
Pls help: Mr edward is now 3 times as old as his daughter. In 15 years time, the sum of their ages will be 86.

Let y represent the ounces of oil present
7/19 = y/38
19 y= 7×38
19y= 266
y= 266/19
= 14
Hence there are 14 ounce of oil present

Mr. Gomez needs to rent a moving truck. Company "A" charges $75 plus a $50 a day and Company "B" charges $105 plus $35 a day. Write an equation that can tell after how many days would the price be the same.
Answer: 75+50x= 105+35x , required equation.
Step-by-step explanation:
Let x = Number of days
Given: Company "A" charges $75 plus a $50 a day.
Total charge = 75+50x
Company "B" charges $105 plus $35 a day.
Total charge = 105+35x
When both are same , equation becomes
75+50x= 105+35x
So, Required equation: 75+50x= 105+35x
Write the slope-intercept form of the equation

Which inequality best represents that ice cream at −2°C is cooler than ice cream at 3°C? Group of answer choices −3°C > 2°C −3°C < 2°C 3°C > −2°C 3°C < −2°C
Answer:
3°C > - 2°C
Step-by-step explanation:
Ice cream 1 = - 2°C
Ice cream 2 = 3°C
Lower temperatures are colder (cooler) than higher temperature values.
Hence, ice cream at - 2°C is cooler than ice cream at 3°C.
Hence, a temperature of 3°C is higher (greater) than - 2°C. Hence - 2°C is cooler (colder) than 3°C
Hence,
3°C > - 2°C
Solve this equation.
75 – 3.5y – 4y = 4y + 6
Answer:
y=6
Step-by-step explanation:
75-3.5y-4y=4y+6
combine like terms)
75+(-3.5y-4y)=4y+6
75-7.5y=4y+6
add 4y to each side to combine the terms) 75+(-7.5y-4y)=6
75-11.5y=6
subtract 75 from each side to isolate the variable) -11.5y=-69
divide by -11.5 to isolate the variable) -11.5y/-11.5=-69/-11.5
y=6

Determine the area of the figure, in square meters. HELP ME PLAES BRIANEST ASAP PLEASE HAVE A EXPLIATION
Answer:
100 sq m
Step-by-step explanation:
if you fill in the shape to be a big rectangle it will be 8 x 22 =176 sq m
then the little piece on the left that is taken out is 2 x 2 = 4 sq m
the piece on the right is 6 x 12 = 72 sq m
so subtract them from the big rectangle
176 - 4 - 72 = 100 sq m
Answer:
100m^2
Step-by-step explanation:
To do this we need to break the shape into sections as illustrated in the picture I attached, I color coded the squares to make it easier to explain. Now we just find the area of each shape and add them all together.
Area= base•height
So for the purple shape:
6•2=12
Orange:
8•8=64
Green:
2•12=24
In total:
12+64+24=100
And since it's area it would be in square units which just means it'd look like this:
[tex] {100m}^{2} [/tex]
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!
