Answer:
An acute triangle.
Step-by-step explanation:
There is a rule that if a triangle is equilateral, then it also must be acute. A right and obtuse triangle will always have a scenario where one of the sides is longer both of the other sides. And, if the triangle has at least one side longer than the other, it cannot be a equilateral triangle. Therefore, an equilateral triangle can also be an acute triangle. Hope this helps!

Step-by-step explanation:
devide (a2+ 7a+ 12)÷ (a+3)
Answer:
(a - 3) • (a - 4)
Step-by-step explanation:
The first term is, a2 its coefficient is 1 .
The middle term is, -7a its coefficient is -7 .
The last term, "the constant", is +12
Multiply the coefficient of the first term by the constant 1 • 12 = 12
Find two factors of 12 whose sum equals the coefficient of the middle term, which is -7 .
-12 + -1 = -13
-6 + -2 = -8
-4 + -3 = -7 That's it
Rewrite the polynomial splitting the middle term using the two factors, -4 and -3
a2 - 4a - 3a - 12
Add up the first 2 terms, pulling out like factors :
a • (a-4)
Add up the last 2 terms, pulling out common factors :
3 • (a-4)
Add up the four terms
(a-3) • (a-4)

Step-by-step explanation:
baker eats = 34 pounds
jadarius eats = 34 x 3
= 102 pounds
darrick eats = 20 ounces

The table shows all the possible outcomes for spinning the pointer of the spinner with four equal sized sections labeled 1–4 and another spinner with four equal sized sections labeled A-D. What is the probability that the two pointers will land on an odd number and the letter c? Give the probability as a percent.
Answer:
12.5%
Step-by-step explanation:
There are two types of spinners here and the outcome of them is independent. That means
P(odd number,C) = P(odd number) * P(C)
There are two odd numbers out of four numbers in the first spinner. The chance of odd number will be:
P(odd) = 2/(2+2)= 1/2= 50%
There are four letters and the desired outcome is C. The chance for C will be:
P(C)= 1/4= 25%
Then the chance will be:
P(odd number,C) = P(odd number) * P(C)
P(odd number,C) =50% * 25% = 12.5%

Answer: Multiply the radius of the half circle by 2.
Step-by-step explanation: The dotted line that connects the two endpoints of the half circle is the diameter of the circle. To find the diameter of the circle, you will need to multiply the radius of the half circle by 2, since the radius is half of the diameter.
Determine whether the conclusion is valid. Explain.
You want to determine the number of students in your school who have visited a science museum. You survey 50 students at random. Twenty have visited a science museum, and thirty have not. So, you conclude that 40% of the students in your school have visited a science museum.
A. yes; The sample is representative of the population, selected at random, and large enough to provide accurate data. So, the sample is unbiased and the conclusion is valid.
B. yes; The sample is representative of a specific group, selected based on age, and small enough to provide accurate data. So, the sample is biased and the conclusion is valid.
C. no; The sample is not representative of the population because students who are older have had more opportunities to visit a science museum. So, the sample is biased and the conclusion is not valid.
D. no; The sample is representative of the population, selected at random, and too large. So, the sample is unbiased and the conclusion is not valid

Find the area of the parallelogram. Pls explain and I will give brainliest!
Answer:
C: 697 in^2
Step-by-step explanation:
Since parallelograms have parallel lines, the 41 in and 33 in have the same area, the 17 inch and the opposite have the same area too.
You don't need any solution for this since this question already gave you the answer without needing to do any calculation except for finding the area of the parallelogram.
41 x 17 = 697in^2

A fast-food restaurant must apply an 8.5% tax on every sale it makes. How much tax must it charge a customer who purchases a total of $18.50 in food?
Answer: $1.57
Step-by-Step Explanation:
Study.com says: “the formula for calculating the sales tax on a good or service is: selling price x sales tax rate, and when calculating the total cost of a purchase, the formula is: total sale amount = selling price + sales tax,” (study.com, How to Calculate Sales Tax).
So, to find the amount of money they are charging for taxes, we need to use the formula: $18.50 x 8.5%. The selling price is the total sum of the purchase, and the sales tax rate is the percentage number that is apply to every sale as taxes.
Here’s how we solve:
1. To multiply, we first need to change our percentage into a decimal by dividing it by 100. —> 8.5/100 = 0.085
2. Multiply the purchase times the sales tax rate, which is converted into a decimal. —> 18.50 x 0.085 = 1.5725
3. Because money only uses the tenths and the hundredths places, we round up. —> 1.5725 ~ 1.573 ~ 1.57
4. Our answer for the tax amount charged in money is $1.57
Hope this helps!
Solve for the variable: 4x − (9 − 3x) = 8x − 1
Answer:
x = - 8
Step-by-step explanation:
4x - 9 + 3x = 8x - 1
7x - 9 = 8x - 1
7x - 8x - 9 = 8x - 8x - 1
- x - 9 = - 1
- x - 9 + 9 = - 1 + 9
- x = 8
- x ÷ - 1 = 8 ÷ - 1
x = - 8

Debra and Alexandria can finish a plowing job in two hours if they work together. Debra can do the job in 7 hours by herself. How long would it take Alexandria to finish the same job alone?
Answer:
2 hours 48 minutes
Step-by-step explanation:
Debra=1 plowing job / 7 hours
Debra+Alexandra=1 plowing job / 2 hours
1/2-1/7
=7/14-2/14
=5/14
=1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)
14/5 hour=2 hours 48 minutes (hope hits helps)
Alexandria to finish the same job alone in, 2 hours 48 minutes
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Debra and Alexandria can finish a plowing job in two hours if they work together.
And, Debra can do the job in 7 hours by herself.
Hence, We get;
For Debra = 1 plowing job / 7 hours
Debra + Alexandra = 1 plowing job / 2 hours
Hence, Time to take Alexandria to finish the same job alone is,
= 1/2 - 1/7
= 7/14 - 2/14
= 5/14
= 1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)
= 2 hours 48 minutes
Thus, Alexandria to finish the same job alone in, 2 hours 48 minutes

Find x and y
Show all the work
Answer:
x = 16
y = 116
Step-by-step explanation:
Given is a figure of isosceles trapezoid. One pair of opposite sides are parallel and non-parallel sides acts as it's transversals.
Therefore,
4x° + (6x + 20)° = 180° ( interior angles on the same side of transversal)
(6x + 20 + 4x)° = 180°
(10x + 20)° = 180°
10x + 20 = 180
10x = 180 - 20
10x = 160
x = 160/10
x = 16
Measure of base angles of an isosceles trapezoid are equal.
Therefore,
y° = (6x + 20)°
y = 6x + 20
y = 6*16 + 20
y = 96 + 20
y = 116

Answer:

Step-by-step explanation:
Assuming x is the length DB
Δ DSR and Δ DBC are similar, so ratios of corresponding sides are equal, that is
[tex]\frac{DB}{DS}[/tex] = [tex]\frac{DC}{DR}[/tex] , substitute values
[tex]\frac{DB}{10}[/tex] = [tex]\frac{12}{8}[/tex] ( cross- multiply )
8 DB = 120 ( divide both sides by 8 )
DB = 15
That is x = DB = 15

El precio de un auto era de &725000. Me han rebajado un 15% por pagarlo al contado. ¿Cuánto debemos abonar con la rebaja?
Respuesta:
616,250
Explicación paso a paso:
Dado que:
Precio inicial = 725.000
Porcentaje de descuento por pagar en efectivo = 15% = 0,15
El precio con descuento será:
Importe inicial - descuento
Descuento = 0,15 * 725000 = 108,750
Precio con descuento = (725000 - 108750) = 616,250
