Figure ABCD is a trapezoid. Find
the value of x.
3x+3
B
13
4x+2
A
D
X = ?
Answer:
x = 3
Step-by-step explanation:
The midsegment is half the sum of the parallel bases, that is
[tex]\frac{1}{2}[/tex] (3x + 3 + 4x + 2) = 13
[tex]\frac{1}{2}[/tex] (7x + 5) = 13 ( multiply both sides by 2 )
7x + 5 = 26 ( subtract 5 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3

A Speedboat increases in speed uniformly from 20m/s to 30m/s for 12.2 s. What is the acceleration of the speedboat?
Answer:
0.82 m/s^2
Step-by-step explanation:
Given data
initial velocity=20m/s
Final velocity= 30m/s
Time = 12.2s
Applying the formula
a= v-u/t
a= 30-20/12.2
a= 10/12.2
a= 0.819
a=0.82 m/s^2
Sarah bought 18 boxes of 65 pens at $12 a box. She sold 378 of them at 3 for $1.00 and the rest at 4 for $1.00. Find her total profit.
Answer:
$108
Step-by-step explanation:
1 box = $12
18 boxes = 12×18 = $216
Total = 18×65 = 1170 pens
Cost price, Cp = $216
3 = $1
378 = 378/3 = $126
1170-378= 792 pens remaining
4 = $1
792 = 792/4 = $198
Total selling price, sp = 126+198 = $324
Profit = Sp - Cp = 324 - 216 = $108

Answer:
A factor is a circumstance or action that will/would influence an outcome.
A variable is something that is liable to change or something that isn't temporary.
A product is a result of an action or a process.
Coefficient means a quantity is being multiplied by the variable, for instance:
4 (the coefficient) X (the variable) - (the operator) 7 (the constant) = 5 (the constant)
What that looks like is: 4x-7=5.

Themla spent 1/6 of her weekly allowance on dog toys. 1/4 on a dog collar, and 1/3 on dog food. What fraction of her weekly allowance is left?
Answer:
¼ remaining
Step-by-step explanation:
Convert to common numerator of 12:
1/6 = 2/12
1/4 = 3/12
1/3 = 4/12
Total: 9/12
1 - 9/12 = 3/12 = ¼

What is the y-intercept of the graph of the equation 5x + (–2y) = 8?
Answer:
-4
Step-by-step explanation:
5x + (–2y) = 8
-2y = -5x + 8
Divide both sides by -2
y = [tex]\frac{5}{2}[/tex]x - 4

Area of rhombus=[tex]\frac{d1+d2}{2}[/tex]
d1=BD=4
d2=AC=2
so [tex]\frac{4*2}{2}=4[/tex]
area of quadrilateral (rhombus)=4square units
:
Solution given:
diagonal 1:AC=2 unit
diagonal 2:BD=4 unit
it looks like a rhombus
so
area of quadrilateral (rhombus)
=½*(diagonal 1*diagonal2)=½(2*4)=4 square units

Central Fencing has been hired to fence the perimeter of a rectangular field. The length of the field is 42 - W feet, where W is the width of the field, and the area of the field must be more than 432 square feet. Find the bounds on the width of the field.
Answer:
10.3 is the width
Step-by-step explanation:
set up an equation
42w=432
divided both sides by 42
W=10.2857142857
to rounded it to nearest tenth it will be 10.3
to check your answer multiply 10.3 by 42 it will be 432
check check
Answer:
18 ≤ w ≤ 24
Step-by-step explanation:
A = l * w
A ≥ 432 sq ft.
l = 42 - w
432 ≤ (42 - w) (w)
432 ≤ -w² + 42w
w² - 42w ≥ 432
Substitute values for w
w = 18
w = 24
