Multiply
Answer:
148.5 units^2
Step-by-step explanation:
First, find the area of the entire rectangle. The area is 180 because we have to multiply 15*12.
Next, find the area of the triangle. The area is 31.5 because we have to figure out 1/2(7*9)
Finally, you subtract 31.5 from 180.

Jesse needs 10 1/4 feet of chain to complete an outdoor project. He has two small pieces each measuring 2 1/8 feet and a third piece measuring 3 3/4 feet. How many feet of chain does Jesse need to purchase?
Answer:
= 2 1/4 feet
Step-by-step explanation:
Length of chain Jesse needs = 10 1/4 feet
Length of chain Jesse has:
Two small pieces each measuring 2 1/8 feet
= 2 × 2 1/8 feet
= 2 × 17/8
= 34/8 feet
Third piece measuring 3 3/4 feet
Total Length of chain Jesse has = 34/8 feet + 3 3/4 feet
= 34/8 + 15/4
= 34+30/8
= 64/8
= 8 feet
Total Length of chain Jesse has = 8 feet
Length of chain Jesse needs to purchase = Length of chain Jesse needs - Total Length of chain Jesse has
= 10 1/4 feet - 8 feet
= 2 1/4 feet
Length of chain Jesse needs to purchase = 2 1/4 feet

4x=3y+23
4y+3x=-19
solve by substitution. No files pls
Answer:
x = ⁷/₅
y = ⁻²⁹/₅
Step-by-step explanation:
4x = 3y + 23 (×3)
12x = 9y + 69
4y + 3x = -19
3x = -4y - 19 (×4)
12x = -16y - 76
∴ 9y + 69 = -16y - 76
25y = -145
y = ⁻²⁹/₅
12x = 9(⁻²⁹/₅) + 69
12x = 69 - ²⁶¹/₅
12x = ⁸⁴/₅
x = ⁷/₅
Which pair of angles represent
Alternate Exterior Angles?
Please helpppp
Answer:
1 and 8, 4 and 5
Step-by-step explanation:
There are two pairs, 1 and 8, 4 and 5
The angles in each pair must be on opposite sides of the transversal k, and on the outsides of the parallel lines l and m.
3,0 and 4,l what is the y-intercept of the line
Answer:
Step-by-step explanation:
(3,0),(4,1) ⇒ (x₁,y₁),(x₂,y₂)
to find the equation of the line
y-y₁= {(y₂-y₁)/(x₂-x₁)}(x-x₁)
y-0= [(1-0)/(4-3)] (x-3)
y-0 = 1/1(x-3)
y-0 = x-3
y= x-3+0
y=x-3
compare to y=mx+c, where m is the gradient and c is the intercept on y-axis
m=1, c=-3
∴the y-intercept of the line is -3
In triangle HIJ, N is the centroid. If HK = 10, find KI.
Given:
In triangle HIJ, N is the centroid and [tex]HK=10[/tex].
To find:
The value of KI.
Solution:
In a triangle, the centroid of the triangle is the intersection of its medians.
Median of a triangle from a vertex divides the opposite side into two equal parts.
It is given that, N is the centroid. It means JK, HL and IM are the medians of the triangle HIJ.
Since JK is a median of the triangle HIJ, therefore it divides the opposite side IH into two equal parts.
[tex]KI=HK[/tex]
[tex]KI=10[/tex]
Therefore, the value of KI is 10 units.

Step-by-step explanation:
The Royal Fruit Company produces two types of fruit drinks. The first type is pure fruit juice, and the second type is pure fruit juice. The company is attempting to produce a fruit drink that contains pure fruit juice. How many pints of each of the two existing types of drink must be used to make pints of a mixture that is pure fruit juice
Answer:
72 pints of the first type
18 pints of the second type
Step-by-step explanation:
See attachment for complete question
Given
[tex]x \to[/tex] first type
[tex]y \to[/tex] second type
Final volume = 90; So:
[tex]x + y = 90[/tex]
From the question, we understand that:
70% of x and 95% of y gives 75% of the fruit juice
This is represented as:
[tex]70\% * x + 95\% * y = 75\%* 90[/tex]
Make x the subject in [tex]x + y = 90[/tex]
[tex]x = 90 - y[/tex]
Substitute: [tex]x = 90 - y[/tex] in [tex]70\% * x + 95\% * y = 75\% * 90[/tex]
[tex]70\% * (90 - y) + 95\% * y = 75\% *90[/tex]
Express percentage as decimal
[tex]0.70 * (90 - y) + 0.95 * y = 0.75 * 90[/tex]
Open brackets
[tex]63 - 0.70y + 0.95y = 67.5[/tex]
Collect like terms
[tex]- 0.70y + 0.95y = 67.5 - 63[/tex]
[tex]0.25y = 4.5[/tex]
Divide both sides by 0.25
[tex]y = \frac{4.5}{0.25}[/tex]
[tex]y = 18[/tex]
Recall that: [tex]x = 90 - y[/tex]
[tex]x = 90 - 18[/tex]
[tex]x = 72[/tex]

What is P(odd)?
Write your answer as a fraction or whole number.
Answer:
1/3
Step-by-step explanation:
Does the spinner only have these 3 sections?
If so, the probability of spinning an odd number is 1/3. There are a total of 3 possibilities (denominator), and only 1 is odd (numerator).
The P(odd) is the probability of spinning an odd number that would be equal to 1/3.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes

Answer:
3x³ + x² + x + 1
= 3x³ - 3x² + 4x² - 4x + 5x - 5 + 6
= 3x²(x - 1) + 4x(x - 1) + 5(x - 1) + 6
= (x - 1)(3x² + 4x + 5) + 6
but 3x³ + x² + x + 1 = (x - 1).Q(x) + R
=> Q(x) = 3x² + 4x + 5
R = 6
Find the value of g in the figure given below.
Assume that the lines are parallel.
Answer:
d=60-degree (Vertically opposite angles)
e=d=60-degree (Alternate angles)
e+g=180-degree (Being in a straight line)
60+g=180
g=180-60
g=120-degree
Answer:
angle g = 20 degree
Step-by-step explanation:
60 degree + angle g = 180 degree (being co exterior angles)
angle g = 180 - 60
angle g = 120 degree
Note : co interior angles are the angles formed on the exterior of the two parallel lines and which are on the same side of the transversal .

Answer:
(a) x = [tex]128^{o}[/tex]
(b) x = [tex]74^{o}[/tex]
Step-by-step explanation:
A. sum of angles in a polygon = (n - 2) 180
The polygon given is an irregular pentagon, where n = 5
So that;
sum of angles in a pentagon = (5 - 2) 180
= 3 x 180
= [tex]540^{o}[/tex]
Thus,
x + 90 + 76 + 110 + 136 = [tex]540^{o}[/tex]
x + 412 = [tex]540^{o}[/tex]
x = [tex]540^{o}[/tex] - 412
x = [tex]128^{o}[/tex]
B. The polygon given is an irregular pentagon, where n = 5.
Let the supplementary angle with angle 38 be represented by y,
y + 38 = 180
y = 180 - 38
= [tex]142^{o}[/tex]
y = [tex]142^{o}[/tex]
Let the supplementary angle with x be represented by z, so that;
z + 72 + 120 + 100 + 142 = [tex]540^{o}[/tex]
z + 434 = [tex]540^{o}[/tex]
z = [tex]540^{o}[/tex] - 434
= [tex]106^{o}[/tex]
z = [tex]106^{o}[/tex]
But, x + z = [tex]180^{o}[/tex]
Then;
x + [tex]106^{o}[/tex] = [tex]180^{o}[/tex]
x = [tex]180^{o}[/tex] - [tex]106^{o}[/tex]
= [tex]74^{o}[/tex]
x = [tex]74^{o}[/tex]

Consider the figure below, where line a is parallel to line b:
Angle 4 = 12m - 4
Angle 5 = 10m + 20
Calculate the measure of Angle 5.
Answer:
Angle 5= 140
Step-by-step explanation:
I assume you are talking about parrallel lines and a transversal. If that is the case, I can guess that angles 4 and 5 are alternate exterior angles. Therefore they are congruent.
12m-4=10m+2012m=10m+24 You add 4 to -4 and 202m=24 You subtract 10m from 10m and 12mm=12 Divide both sides by 210(12)+20 Substitute m for 12 in the equation for Angle 5120+20 Multiply 10 by 12140 Add 120 and 20The variables y and x^2 are directly
proportional. It is given that the difference
between the values of ý when x = 2 and x = 5
is 20. Form an equation relating y and x.
Answer:
y = [tex]\frac{20}{21}[/tex] x²
Step-by-step explanation:
Given that y and x² are directly proportional then the equation relating them is
y = kx² ← k is the constant of proportion
When x = 2
y = k × 2² = 4k
When x = 5
y = k × 5² = 25k
Then
25k - 4k = 20 ( difference between values is 20 )
21k = 20 ( divide both sides by 21 )
k = [tex]\frac{20}{21}[/tex]
y = [tex]\frac{20}{21}[/tex] x² ← equation of proportion
express the sine, cosine and tangent of the following angles as ratios
Answer:
Step-by-step explanation:
sin(x) = opposite / hypotenuse = 21/29
cos(x) = adjacent / hypotenuse = 20/29
tan(x) = opposite / adjacent = 21/20
sin(y) = opposite / hypotenuse = 20/29
cos(y) = adjacent / hypotenuse = 21/29
tan(y) = opposite / adjacent = 20/21
