Answer:
Base = 26 in
Step-by-step explanation:
Recall the formula for the area of a triangle as:
Area = (Base x Height) / 2
In our case, this formula converts into:
546 in^2 = Base x 42 in /2
multiply both sides by 2 to get rid of fractions:
1092 in^2 = Base x 42 in
divide both sides by "42 in" to isolate the Base completely
1092 in^2 / 42 in = Base
Therefore Base = 26 in

6. The net of a rectangular prism and its dimensions are shown in the diagram.
8 in.
8 in.
2 in
2 in.
12 in.
12 in
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]
[tex]SA = 272[/tex]
The total surface area is 272 square inches
The hypotenuse of a right triangle measures 15 cm and one of its legs measures 4 cm.
Find the measure of the other leg. If necessary, round to the nearest tenth.
[tex]15^2-4^2=225-16\\=209[/tex]
[tex]\sqrt{209}[/tex]≈14.9
Answer:
14.5
Step-by-step explanation:
15x15=225
4x4=16
225-16=209
The square root of 209 is 14.4568322948.
Which rounds to 14.5
In a class.
12 of the 18 boys can whistle
9 of the 12 girls can whistle.
Hassan says,
*A higher proportion of boys can whistle compared to girls."
Is he correct?
You must show your working.
Answer:
he is correct because 12 of the boys can whistle and only 9 of the girls can whistle and 9 is a smaller number than 12 so he is correct
Which linear inequality represents the solution set graphed?
A. y≥4x+5
B. y>4x-5
C. y≥4x-5
D. y>-4x-5
The linear inequality (B) y>4x-5 represents the given solution set graph.
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.

A parallelogram has vertices (5,0), (3, -3), (-4, -3) and (-2, 0) The
diagonals of the parallelogram intersect at their midpoints. A. What are the coordinates of the
intersection of their diagonals? Justify the answer algebraically.
Answer:
(0.5 , -1.5)
Step-by-step explanation:
intersection of their diagonals (E): right at the mid-point of segment AC or BD
A (5 , 0) and C (-4 , -3): E (x , y)
x = (5 + -4 ) / 2 = 0.5
y = (0 + -3 ) / 2 = - 1.5
E ( 0.5 , - 1.5)
check with BD: x = (3 + -2) / 2 = 0.5 y = (-3 + 0) / 2 = - 1.5

, 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.
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

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

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
Does someone know the answer to this?
Answer:
both sides are congruent meaning it is a 45/45 triangle. that makes y=45. you can then use sin(45)=x/12 which when solved is 8.49 approximately
