Question:
Marco plotted the following points on the number line.
Point A: 0.3 Point B: 3/4 Point C: 11/4 Point D: 0.7
Which point did he plot incorrectly?
Answer:
Point D
Step-by-step explanation:
Given
[tex]Point\ A= 0.3[/tex]
[tex]Point\ B= \frac{3}{4}[/tex]
[tex]Point\ C= \frac{11}{4}[/tex]
[tex]Point\ D= 0.7[/tex]
Required
The incorrectly plotted point
Number plotted on a number line increases from left to right. This implies that:
[tex]A < B < C < D[/tex]
Substitute the values for the given points
[tex]0.3 < \frac{3}{4} < \frac{11}{4} < 0.7[/tex]
Express as fractions
[tex]0.3 < 0.75 < 2.75 < 0.7[/tex]
Up till 2.75, the order of the numbers is correct.
However, 0.7 is less than 0.75 and 2.75
So, 0.7 is not placed correctly.
This implies that point D is not correctly placed
Write the equation of a line in slope-intercept form with a slope of 10 and passes through (–4, – 25).
Answer:
y = 10x + 15
Step-by-step explanation:
y +25 = 10(x+4)
y = 10x + 40 - 25
y = 10x + 15

Given: ΔWXY is isosceles with legs WX and WY; ΔWVZ is isosceles with legs WV and WZ. Prove: ΔWXY ~ ΔWVZ Triangle W X Y is shown. Line segment Z V is drawn parallel to side Y X to form triangle W V Z. Complete the steps of the proof. ♣: ♦: ♠:
Answer:
The answer is below
Step-by-step explanation:
Two triangles are similar if the ratio of their corresponding sides are in the same proportion.
1. ΔWXY is isosceles with legs WX and WY (given)
2. ΔWVZ is isosceles with legs WV and WZ (given)
3. WX = WY, WV = WZ (definition of an isosceles triangle)
4. [tex]\frac{WX}{WY}=1\\\\[/tex]
[tex]\frac{WX}{WY}=\frac{WZ}{WZ} \ \ \[/tex] (definition of ≅)
5. (WZ)(WX) = (WY)(WZ) (multiplication property)
6. (WZ)(WX) = (WY)(WV) (substitution property).
7. [tex]\frac{WY}{WZ}=\frac{WX}{WV}[/tex] (property of proportion)
8. ∠W = ∠W (reflexive property)
9. ΔWXY ~ ΔWVZ (side - angle - side similarity postulate)
Answer:
♣:
✔ WX = WY; WV = WZ
♦:
✔ substitution property
♠:
✔ SAS similarity theorem

Find x, y, and z in the figure.
Answer:
Since x + y + z = 180° and z = 90°, y + z = 90°
Thus x + y = z
Step-by-step explanation:
Ok, 20 points for this one
Answer:
x = 7Step-by-step explanation:
2 angles are added to result in = 180°
therefore
180 = 97 - 3x + 69 + 5x
180 = 166 + 2x
2x = 180 - 166
2x = 14
x = 14 ÷ 2
x = 7 ✅The value of x = 7

hey i need some help with a fraction this is the question 17*5/8
Answer:
Fraction: 10 and 5/8
Step-by-step explanation:
17 × 5/8
85/8
Answer:[tex]10\frac{5}{8}[/tex] or 10.625
Step-by-step explanation:
First of all, note that 17 is the same as 17/1 since 17 divided by 1 is 17. Therefore, start by setting up the problem like this:
[tex]\frac{17}{1} X \frac{5}{8}[/tex]
Multiply the numerators together (17 x 5 = 85) and multiply the denominators together (1 x 8 = 8) and make it into one fraction like so:
[tex]\frac{85}{8}[/tex]
Convert the improper fraction above to a mixed number to get the answer:
[tex]=10\frac{5}{8}[/tex]

4-6x=y2
Step-by-step explanation:
Using factor theorem , show that (x -4) is a factor 2x3 + x2 -26x - 40 and hence factorize completely.
Step-by-step explanation:
if x-4 is a factor of 2x^3 + x^2- 26x - 40
then f(4) = 0
f(x) = 2x^3 + x^2- 26x - 40
f(4) = 2(4)^3 + (4)^2 - 26(4) - 40
f(4)= 2(64) + 16 - 104 - 40
f(4) = 128 + 16 - 104 - 40
f(4) = 0
hence factorize completely is the photo

Given cos theta = - 2/5 and sin theta < 0, find the six trigonometric values. I need help with this
Answer:
[tex]\sin\,\theta =-\frac{\sqrt{21} }{5}[/tex]
[tex]\tan\,\theta =\frac{\sqrt{21} }{2}[/tex]
[tex]\sec\,\theta = \frac{-5}{2}[/tex]
[tex]cosec\,\theta =\frac{-5}{\sqrt{21} }[/tex]
[tex]\cot\,\theta =\frac{2}{\sqrt{21} }[/tex]
Step-by-step explanation:
[tex]\cos\theta =\frac{-2}{5}<0\\sin\theta <0[/tex]
As both [tex]sin\,\theta<0,\,\cos\,\theta <0[/tex],
[tex]\theta[/tex] lies in the third quadrant.
In the third quadrant,
[tex]\sin\theta<0,\,\cos\,\theta <0\,,\,\sec\,\theta<0,\,cosec\theta<0,\,tan\,\theta>0,\,cot\,\theta>0[/tex]
[tex]\sin\,\theta =-\sqrt{1-\cos^2\,\theta} \\=-\sqrt{1-(\frac{-2}{5})^2 } \\\\=-\sqrt{1-\frac{4}{25} }\\\\=-\sqrt{\frac{25-4}{25} }\\\\=-\frac{\sqrt{21} }{5}[/tex]
[tex]\tan\,\theta = \frac{\sin\,\theta}{\cos\,\theta }\\\\=\frac{\frac{-\sqrt{21} }{5} }{\frac{-2}{5} }\\\\=\frac{\sqrt{21} }{2}[/tex]
[tex]\sec\,\theta =\frac{1}{\cos\,\theta }\\\\=\frac{1}{\frac{-2}{5} }\\\\=\frac{-5}{2}[/tex]
[tex]\ cosec \,\theta = \frac{1}{sin\,\theta }\\\\=\frac{1}{\frac{-\sqrt{21} }{5} }\\\\=\frac{-5}{\sqrt{21} }[/tex]
[tex]\cot\,\theta =\frac{1}{\tan\,\theta}\\\\=\frac{1}{\frac{\sqrt{21} }{2} }\\\\=\frac{2}{\sqrt{21} }[/tex]

If angle DCA measures 40 degrees, what does angle ACB measure?
*see attachement for the diagram that is being referred to
Answer:
m<ACB = 50°
Step-by-step explanation:
From the diagram, <DCB is a right angle = 90°
Therefore:
m<DCA + m<ACB = 90° (complementary angles)
m<DCA = 40° (given)
Thus:
40° + m<ACB = 90° (Substitution)
m<ACB = 90° - 40° (Subtraction property of equality)
m<ACB = 50°

Answer:
Step-by-step explanation:
- 50 + (5 / 13)p this says negative 50 plus 5/13 times p
if p = -26 what does this epression evaluate to?
- 50 + (5 / 13) × p p = -26 substitute the value of p into the expression
- 50 + (5 / 13) × (-26)
- 50 + (5 (-26) / 13) I just rewrote the expression to make it clearer
that the -26 in -26/1 and the 5 in 5 / 13 are
both in the numerator over denominator 13
- 50 + (5 (-26) / 13) -26 / 13 evaluates to -2
-50 + (5)(-2)
-50 + (-10)
-50 - 10
-60

Twice a year, the P.E. teachers test the fitness level of all sixth-grade students at Walker Middle School. The students' weights and heights are measured as well as the time it takes each student to run a mile and the number of sit-ups and push-ups each student can do.
Which of the following are statistical questions that can be answered by the data gathered in the first fitness test of the year?
How many chin-ups can a sixth-grade boy do?
What are the weights of the sixth-grade boys?
How many sixth-grade students are there?
How many push-ups can a sixth-grade girl do?
What is the shortest height of the sixth-grade students?
What are the heights of the eighth-grade girls?
Answer : b: How many push-ups can a sixth grade girl do? and d:What are the weights of the sixth grade boys?
Answer:
How much do sixth grade boys weigh?
How many push-ups can a sixth grade girl do?
Step-by-step explanation:
A statistical question is one that has a variable answer.
Determine which questions are statistical questions and can be answered with the data gathered in the fitness test.
The questions "How many sixth grade students are there?" and "What is the shortest height of the sixth grade students?" can be answered with the data gathered in the fitness test. However, they do not have variable answers, so they are not statistical questions.
The questions "What are the heights of the eighth grade girls?" and "How many chin-ups can a sixth grade boy do?" do have variable answers, so they are statistical questions. However, these questions cannot be answered with the data gathered in the fitness test.
The questions "How much do sixth grade boys weigh?" and "How many push-ups can a sixth grade girl do?" do have variable answers, so they are also statistical questions. These questions can be answered with the data gathered in the fitness test.
