Laura drove 638 miles in 11 hours at the same rate how long would it take her to drive 406 miles
Answer:
Step-by-step explanation:
This is a d = rt problem; but since it is linear, then proportions will work too. Set up the proportion with miles on top and hours on the bottom:
[tex]\frac{miles}{hrs}:[/tex]
Then put the numbers in where they go, keeping in mind that miles goes with miles and hours goes with hours in the ratios, and that our unknown is time (hours):
[tex]\frac{miles}{hrs}:\frac{638}{11}=\frac{406}{x}[/tex] and cross multiply to solve:
638x = 4466 so
x = 7 hrs

For what value of k is the expression x4+kx2+36 a perfect square?
Answer:
12
Step-by-step explanation:
Because if you see clearly that is the only answer that makes the most sense!
The value of m is the expression x⁴ + mx² + 64 a perfect square will be 16.
What is a perfect square trinomial?A perfect square trinomial formulation can be created by taking the binomial equation's squared. If and then only if a trinomial satisfying the criterion b² = 4ac has the form ax² + bx + c, it is indeed a perfect square.
The equation is given below.
⇒ x⁴ + mx² + 64
Then the value of a, b, and c will be 1, m, and 64, respectively. Then the equation will be given as,
b² = 4ac
m² = 4 x 1 x 64
m² = 265
m² = 16²
m = 16
The value of m is the expression x⁴ + mx² + 64 a perfect square will be 16.

Luke randomly selects 25 students from his school and asks each of them how many minutes they read each night to find out how much, on average, students at his school read. This represents which type of data collection
Answer:
Simple random sampling
Step-by-step explanation:
Luke wants to study average minutes students read each night. For that matter, he has selected a 'sample' of 25 students from entire 'population' of students in school.
He has selected the sample students randomly, for collecting data related to minutes of study each night. He also collects data from them directly ie with primary contact with them.
So, primary data collection, simple random sampling - has been used as a type of data collection.

1 In triangle MNP the measure of angle NPM is 80° and the measure of angle MNP is 22.5°.
What is the measure of angle PMN in degrees?
Answer:
77.5°
Step-by-step explanation:
Recall that the sum of angles in a triangle is 180 degrees.
Given the triangle MNP with the measure of angle NPM is 80° and the measure of angle MNP is 22.5°
Then
angles NPM + MNP + PMN = 180 degrees
This means that
80 + 22.5 + PMN = 180
102.5 + PMN = 180
Collect like terms
PMN = 180 - 102.5
= 77.5°.

What is the missing term?
Answer:
Missing term = 6x
Step-by-step explanation:
We got:
=> 4x by multiplying +4 and x (x * 4 = 4x)
=> 12 by multiplying +4 and +3 (4 * 3 = 12)
=> 2x² by multiplying 2x and x (2x * x = 2x²)
Similarly we will get the "missing term" by multiplying 2x and +3
=> Missing term = 6x, (2x * 3 = 6x)
Hope this helps!
What's the value of X for the figure below?
Answer:
75+30+x+30+x+75=360
210+2x=360
2x=360-210
2x=150
x=150/2
x=75
Step-by-step explanation:
therefore x=75 degree

Professor Turner wrote the expression below on the chalkboard for his team at the Research Center. He asked the scientists there to write an equivalent expression that eliminated the parentheses.
Answer:
12x + 18y + 6z + 4x - 4z
Step-by-step explanation:
Given the expression : 3(4x + 6y + 2z) + 4(x – z)
To eliminate the parenthesis ; we use the distributive property :
3(4x + 6y + 2z) + 4(x – z) becomes ;
3*4x + 3*6y + 3*2z + 4*x + 4*-z
12x + 18y + 6z + 4x - 4z
Hence,
12x + 4x + 18y + 6z - 4z
16x + 18y + 2z
90%in the SIMPLEST form
Answer:
[tex]90\% = \frac{90}{100} \\ = \frac{9}{10} = 0.9[/tex]
Answer:
The simplest form of
90/100
is
9/10
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 90 and 100 is 10
Divide both the numerator and denominator by the GCD
90 ÷ 10
100 ÷ 10
Reduced fraction:
9
10
Therefore, 90/100 simplified to lowest terms is 9/10.

Here's the number line what fraction of 1 foot is 3 inches what fraction of one yard is 3 inches explain
Answer:
1/4 and 1/12
Step-by-step explanation:
We know that
1 foot = 12 inches
therefore, 1 inch = 1/12 foot
hence, 3 inches = 3/12 foot
= 1/4.
Therefore, the required fraction is = 1/4
Similarly,
1 yard = 36 inches
This implies 1 inch = 1/36 yard
Hence, 3 inches = 3/36 = 1/12
Therefore, the required fraction = 1/12
Find the value of x. Help fast me need help
Answer:
(5x + 16) + 102 + 92 + 100 = 360
(5x + 16) + 294 = 360
-294 -294
5x + 16 = 66
-16 -16
5x = 50
Divide by 5 on both sides.
x = 10 degrees
A quadrilateral will always equal 360 degrees
A triangle will always equal 180 degrees.

Zachary earns $5 per hour, and he makes a $20 bonus.
His equation is shown in red on the graph, y = 5x + 20.
Maisy earns $7.50 per hour, and she makes a $5 bonus.
Her equation is shown in blue on the graph, y = 7.50x +
5.
After how many hours do they earn the same amount of
money? Where do you see this on the graph?
Answer:
6 hours
we see it at the x value of 6 on the graph
Step-by-step explanation:
I graphed it too using desmos then located the point where they cross, the solution point, and it was at the x value of 6 and they will have made $50 by the way in case you wanted to know that too so we see that on the graph at the point (6,50) is where they make the same amount of money.

Drag each length to match it to an equivalent length. 2 yards 5 inches returned to choices list. 2 feet 8 inches4 yards9 feet2 yards 5 inches Length Equivalent Length 32 inches 77 inches 144 inches 3 yards
Answer:
2 yards 5 inches will be equivalent to 77 inches
Step-by-step explanation:
Given length -
2 yards 5 inches
One yard has 36 inches
Two yards will have 2*36 = 72 inches
Thus, 2 yards 5 inches will sum up to 72 inches + 5 inches = 77 inches
Hence, 2 yards 5 inches will be equivalent to 77 inches
Answer:
3 yards = 9 feet
77 inches = 2 yards 5 inches
48 inches = 1 yard 1 foot
32 inches = 2 feet 8 inches
