, 87% of the students in the 7th grade
got a passing grade. If there are 48 students in the 7th grade, how
many of students got a passing grade?
Answer:
41 students get a passing score.
Step-by-step explanation:
48*0.87 = 41.76
You remove the 0.76 because you can not have a percent of a student.
There are two numbers. The larger number is five more than the smaller
number. Three times the smaller number increased by the larger number
equals 147. Find the two numbers.
please help!!!! im in a test!!!!!!!!
Answer:
35.5 + 40.5
Step-by-step explanation:
smaller number = x
large number = x +5
3x + x +5 = 147
4 x +5 = 147
4x = 142
x = 35.5
x +5 = 40.5

Step-by-step explanation:
(-7+1)/(5-1)=-6/4= -3/2 is the slope
answer is C
Answer:
C
Step-by-step explanation:
The formula for slope is rise/run
Rise is the difference between the y coordinates
Run is the difference between the x coordinates
To find the rise and run:
ex.
(a, b), (c, d)
rise:
d-b
run:
c-a
Slope:
d-b/c-a
In this situation:
rise:
-7-(-1)
run:
5-1
Slope:
-7-(-1)/5-1
= -6/4
=-3/2
So the answer is C
log x - log 6 = 2 log 4
log(x) - log(6) = 2 log(4)
Condense the left side, using the property log(a) - log(b) = log(a/b) (if b ≠ 0):
log(x / 6) = 2 log(4)
Rewrite the right side, using the property n log(a) = log(aⁿ ):
log(x / 6) = log(4²)
log(x / 6) = log(16)
Cancel the logarithms (i.e. take the exponential of both sides):
exp(log(x / 6)) = exp(log(16))
x / 6 = 16
Solve for x :
x = 6 × 16
x = 96
Which linear inequality represents the solution set graphed?

What is linear equality?A linear inequality in mathematics is an inequality involving a linear function. One of the symbols for inequality is found in linear inequality. It displays non-equal data in graph style. The boundary line that separates the coordinate plane into two halves by a linear inequality represents the solutions to the inequality in one half. For > and, the border line is solid, and for and, it is dashed. Typically, the half-plane that resolves the inequality is shaded.So, the linear inequality that represents the graph:
Graph the inequation as follows:
(A) y≥4x+5 (Refer to attached Graph 1)(B) y>4x-5 (Refer to attached graph 2)(C) y>-4x-5 (Refer to attached graph 3)Now, we can easily notice that graph 2 which is of equation (B) y>4x-5 matches the given graph.
Therefore, the linear inequality (B) y>4x-5 represents the given solution set graph.

find the area plz and thank u
Answer:
A = 173.82
Step-by-step explanation:
[tex]A = 2 (1 + \sqrt{2}) a^{2}[/tex]
a = 6
substitute 6 for a
A = 2 (1 + [tex]\sqrt{2}[/tex]) [tex]6^{2}[/tex]
solve:
A = 2 (1 + [tex]\sqrt{2}[/tex]) 36
A = 173.82
Answer:
Around 173.8 km (rounded to the nearest tenth of a km
Step-by-step explanation:
The area of an octagon can be found using the expression:
A=2(1+sqrt of 2)a^2
plug your side of 6 in to create the following equation:
A=2(1+sqrt of 2)(6^2)
Solve for A:
A= (2 + 2*sqrt of 2)(36) I multiplied 6 by 6 to get 36 and used distributive property on the other section.
A=72+72sqrt of 2
plug that in a calculator and you get around 173.8 km

[tex] \sqrt{121} [/tex]
Answer: 11
Step-by-step explanation:
When you do square root, you're just finding the number that can be multiplied by itself to get what's inside the √ .
So, when you do √121 , you'll get 11. You can check your answer by going backwards: multiply 11 by itself.

A bus is going to a museum 135 miles away. The bus will travel at 30 miles per hour. How long will it take the bus to get
to the museum?
Answer:
4.5 hours
Step-by-step explanation:
distance equals rate times time, a relationship that can be solved for time:
time = distance / rate
Here the time is (135 miles) / (30 mph) = 4.5 hours
The bus requires 4.5 hours to get to the museum.

What is the total surface area of the rectangular prism in square inches?
Answer:
272 square inches
Step-by-step explanation:
Given
[tex]l = 8[/tex] --- length
[tex]w = 2[/tex] --- width
[tex]h = 12[/tex] ---- height
Required
Determine the total surface area (SA)
This is calculated using:
[tex]SA = 2 * (lw + wh + lh)[/tex]
[tex]SA = 2 * (8*2+2*12+8*12)[/tex]
[tex]SA = 2 * 136[/tex]

x=11 should be the answer lmk if so
Answer:
x = 18
Step-by-step explanation:
m∠1 & m∠3 are vertical angles. By definition of vertical angles, their measurements will be the same.
It is given that:
m∠1 = 4x - 14
m∠3 = 58°
Set the two angles equal to each other:
4x - 14 = 58
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 14 to both sides of the equation:
4x - 14 (+14) = 58 (+14)
4x = 72
Next, divide 4 from both sides of the equation:
(4x)/4 = (72)/4
x = 72/4 = 18
18 is your answer for x.
