___<square root of 73<___
Answer:
see explanation
Step-by-step explanation:
Consider perfect squares on either side of 73, that is
64 < 73 < 81 , then
[tex]\sqrt{64}[/tex] < [tex]\sqrt{73}[/tex] < [tex]\sqrt{81}[/tex] , that is
8 < [tex]\sqrt{73}[/tex] < 9
Answer:
8<square root of 73<1
i think this are the integers that are closest to the number in the middle.
If 3x+4y=4 and 2x+y=1, then the value of 2x+3y is equal to
Answer:
3.
Step-by-step explanation:
3x + 4y = 4..........1
2x + y = 1.............2 Multiply this by 4:
8x + 4y = 4 Subtract this from equation 1:
-5x = 0
x = 0.
So substituting in equation 2:
2(0) + y = 1
y = 1.
Therefore 2x + 3y = 2(0) + 3(1) = 3.
can someone help me with these 2?

Like drives to his grandmother’s house on Saturday. For the first three hours, he drives at a constant sped of 50 miles per hour.
Step-by-step explanation:
if you're asking for distance then,
V = s / t
50 mph = s / 3 hrs
50 mph × 3 hrs = s
150 miles = s

An inequality is a statement that compares two expressions that are strictly equal.
True or false
Answer:
False
Step-by-step explanation:
an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
Answer:
False.
Step-by-step explanation:
In truth, an inequality is a statement marked by any of these signs:
< less than
> greater than
[tex]\leq[/tex] less than or equal to
[tex]\geq[/tex] greater than or equal to
For example, if I wrote x < y. This means that x must always be less than y. Now, if I wrote c [tex]\geq[/tex] d, this means that c can be greater than OR equal to d. If you see a line under one of these signs, it means (sign) or equal to. So at times, they can be equal, but not strictly. That would be an equation.

Remy drink 2 1/4 cups of water every 1 4/5 hours. How many cups of water does he drink in 1 hour? Enter your answer as a mixed number.
Answer:
The answer is 1 1/4
Step-by-step explanation:
solve by making a ratio!
(2 1/4 cups)/ (1 4/5 hrs)
to find how many cups he can drink in 1 hr, divide both the numerator and denominator by 1 4/5.
(5/4 cups)/ (1 hr)
the question asks for a mixed number. convert 5/4 to a mixed number.
5/4= 1 1/4

Read the conjecture below. Select all of the true statements about this conjecture. If you multiply two numbers, then the product is greater than either number. Select all that apply. a. This conjecture is true. For example, (7)(4) = 28. The product of 28 is greater than 7 and greater than 4. b. This conjecture is false. There is a counterexample that would prove this conjecture false. c. This conjecture is false: . d. There is not enough information.
Answer:
a. This conjecture is true. For example, (7)(4) = 28. The product of 28 is greater than 7 and greater than 4
b. This conjecture is false. There is a counterexample that would prove this conjecture false.
Step-by-step explanation:
The conjecture is true because, if we multiply two numbers, then their product is greater than either number. As given in the example, 7 × 4 = 28. 28 is greater than both 7 and 4.
Also, if we multiplied a fraction by a whole number, the result would be less than one of the numbers. For example 1/2 × 4 = 2. 2 is greater than 1/2 but not 4. So, the conjecture is false.
If we multiply two fractions, the result is less than both fractions. For example 1/2 × 1/4 = 1/8. 1/8 is less than both 1/2 and 1/4. So, the conjecture is false.
The precious two examples show that there are counterexamples which prove that the conjecture is false although it is true sometimes.

O preço a ser pago por uma corrida de táxi inclui uma parcela fixa, denominada bandeirada, e uma parcela que depende da distância percorrida. Se a bandeirada custa R$ 3,44 e cada quilômetro rodado custa R$ 0,90, determine a distância máxima que se pode percorrer com R$20,00
Answer:
18 quilômetros
Step-by-step explanation:
Aqui, queremos determinar a distância máxima que pode ser percorrida com R $ 20
A partir da pergunta, entendemos que cada viagem tem um valor fixo de R $ 3,44 e um valor variável de R $ 0,90 com base na quantidade de quilômetros.
Seja x o número de quilômetros percorridos em R $ 20 Portanto, temos a equação como; 3,44 + 0,9 (x) = 20
0,9x = 20-3,44
0,9x = 16,56
x = 16,56 / 0,9
x = 18,4
Arredondando para o quilômetro mais próximo, a distância máxima que pode ser percorrida com R $ 20 é de 18 quilômetros

Answer:24
Step-by-step explanation:
Each is 7 days a part she dose it every week so just add 7
Answer:
May 24
Step-by-step explanation:
May 3 to May 10 is 7 days or one week
May 10 to May 17 is one week
Linda probably has music lessons every week on the same day
May 17 + one week, or 7 days = May 24
Mixed nuts sell for $7.89 a pound. Leticia fills a bag and weighs it. The bag weighs 2.3 pounds. About how much will the bag of nuts cost? Estimate $7.89(2.3). The bag of nuts will cost about . 12 16 24
Answer:
$18.14
Step-by-step explanation:
step one:
given that Mixed nut sell for $7.89 a pound
that is 1 pound sells for $7.89
2.3 pound will cost x
step two:
x= $7.89(2.3)
x=18.14
Therefore the cost os 2.3 pounds will be $18.14
21:28 = :24
plz help....
Answer:
x=18
Step-by-step explanation:
21:28=x:24
1. rewrite: 21/28 = x/24
2. simplify: 3/4=x/24
3. multiply 24 to both sides: x=18
Rico bicycles at an average speed of 13.5 miles per hour. What distance will Rico bicycle in 3.5 hours? Rico will bicycle 13.5 × 3.5 = 47.25 miles in 3.5 hours. Use estimation to show that the above result is reasonable. Part 1 out of 2 Round 13.5 to and 3.5 to .
Answer:
47.25 milesStep-by-step explanation:
Speed = Distance/Time
Given
Speed = 13.5miles/hour
Time taken = 3.5hours
From the formula;
Distance = Speed * Time
Substitute the given parameters into the resulting equation
Distance = 13.5 * 3.5
Distance = 47.25miles
Hence the distance that Rico bicycle covered is 47.25miles
Triangle DEF contains two congruent acute angles. The sum of the measures of the two congruent acute angles is greater than 90 degrees. Anna concludes that the triangle must be an acute triangle. Which best describes her conclusion?
She is correct. A triangle having at least one acute angle is an acute triangle.
She is correct. The remaining angle of the triangle measures less than 90 degrees.
She is incorrect. The angles measure greater than 90 degrees so the triangle is obtuse.
She is incorrect. The third angle in a triangle with two congruent acute angles is a right angle.
Answer:
She is correct. The remaining angle of the triangle measures less than 90 degrees
Step-by-step explanation:
Edgunity
Anna is correct. The remaining angle of the triangle measures less than 90 degrees.
What are acute angles?Acute angles are angles that measures less than 90 degrees.
Triangle DEF contains 2 congruent acute angles. This means each of those 2 acute angles in the triangle are less than 90 degrees.
The sum of the measure of the two congruent acute angles is greater than 90 degrees.
Therefore,
let
∠D and ∠E be the acute angles.
∠D + ∠E > 90°
An acute triangle:An acute-angled triangle is a type of triangle in which all the three internal angles of the triangle are acute, that is, they measure less than 90°.
The sum of angles of a triangle is 180 degrees.
Since ∠D + ∠E > 90°, then ∠F must be less than 90 degrees.
This simply means the triangle is an acute-angled triangle. Therefore,
Anna is correct.
