Answer:
y = 3
Step-by-step explanation:
x = 4 has an undefined slope meaning on a graph the line is vertical. In order to form a line perpendicular to this, we need a line with zero slope (horizontal line). We need to look strictly at the y coordinate to help determine the equation. In this case, we have a y coordinate of 3. Therefore, the equation will be y = 3.

What is the value of the missing angle?
Answer:
105
Step-by-step explanation:
all angles inside a triangle add up to equal 180, the inside angle at R is 75 degrees, the TP line is obviously a 180 degree angle, because it's just a straight line, so you subtract 75 from 180 to get 105

Answer:
both are 75 degrees
Step-by-step explanation:
the angles add up to 180, as they are also vertical angles
Answer:
b=c since they are vertical angles, b=75 and c=75
Step-by-step explanation: The angle opposite of the given is the same (105) that gives you two measure. Add 105+105 to get 210. A set of vertical angles=360 degrees, take away 210 from 360 to get the measure of b+c. Divide that by two to get the measure of either b or c.

The cost of a t-shirt was $30. Now the t-shirt costs $37.50. What is the percent of change? Do the work on your own paper and write your answer as a number.
Answer:
25%
Step-by-step explanation:
Given that,
Initial cost of a t-shirt = $30
Final cost of a t-shirt = $37.50
We need to find percent of change. The percentage change in any value is given by :
[tex]\%=\dfrac{\text{final value-initial value}}{\text{initial value}}\times 100\\\\=\dfrac{37.5-30}{30}\times 100\\\\=25\%[/tex]
Hence, the percentage error is 25%.

Answer:
4x²+20x+25
Step-by-step explanation:
(2x+5)² = (2x+5)(2x+5)
(2x+5) (2x+5) = 2x(2x) + 2x(5) + 5(2x) + 5(5)
= 4x² + 10x + 10x + 25
= 4x²+20x+25
Please anyone I’ll mark as a branlist
Answer:
the first option is the answer, r = √6
Step-by-step explanation:
[tex]hypotenuse = \sqrt{opposite {}^{2} + adjacent {}^{2} } [/tex]
hypotenuse = q = √12
adjacent = p = √6
opposite = r
substitute the values into the hypotenuse formula
[tex]q = \sqrt{r {}^{2} + p {}^{2} } [/tex]
[tex] \sqrt{12} = \sqrt{r {}^{2} + ( \sqrt{6} ) {}^{2} } [/tex]
[tex]( \sqrt{12} ) {}^{2} = r {}^{2} +6[/tex]
[tex]12 = r {}^{2} + 6[/tex]
[tex]12 - 6 = r {}^{2} [/tex]
[tex]6 = r {}^{2} [/tex]
[tex] \sqrt{6} = r[/tex]
[tex]r = \sqrt{6} [/tex]
Mt. Calvary's budget for a swing set to be built for the Children's Church is $900. If the cost of the swing set should be at least one-fourth as much as the fort, how much can be spent on the fort and still build the swing set?
Answer:
[tex]Amount = \$4500[/tex]
Step-by-step explanation:
Represent Swing Set with S and Fort with F
Given
[tex]S = \$900[/tex]
[tex]S = \frac{1}{4}\ of\ F[/tex] --- S = one-fourth of F
Required
Determine the amount spent on both
Substitute 900 for S in [tex]S = \frac{1}{4}\ of\ F[/tex]
[tex]\$900 = \frac{1}{4} * F[/tex]
Multiply both sides by 4
[tex]4 * \$900 = \frac{1}{4} * F * 4[/tex]
[tex]4 * \$900 = F[/tex]
[tex]\$3600= F[/tex]
[tex]F = \$3600[/tex]
The total amount to be spent it:
[tex]Amount = F + S[/tex]
[tex]Amount = \$3600 + \$900[/tex]
[tex]Amount = \$4500[/tex]
A plane took 3 h 33 min to finish a journey. If the distance of the journey was 2840 miles, at what average speed did the plane travel?
Answer:
800mph
Step-by-step explanation:
Step one
Given data
time taken= 3 h 33 min
= 3.55 hours
distance = 2840 miles
Step two:
from speed= distance/time
substitute
speed= 2840/3.55
speed= 800mph
Hence the speed is 800mph

Step-by-step explanation:
Jervane is planning on buying a coffee and several donuts for a road trip. She wants to spend no more than $20 in total. Coffee costs $3 and donuts are $2 each. Write and solve an inequality to determine the maximum number of donuts that Jervane can buy. Be sure to include units on your answer.
Answer:
8
Step-by-step explanation:
Given:
Total money Jervane can spend = $20.
Cost of a coffee = $3.
Cost of a donut = $2.
To find: Maximum number of donuts Jervane can buy.
Solution:
Let the number of donuts she can buy be [tex]x[/tex].
She wants to spend no more than $20 in total.
So,
[tex]3+2x\leq 20[/tex]
[tex]\Rightarrow 2x\leqslant 20-3[/tex]
[tex]\Rightarrow 2x\leqslant 17[/tex]
[tex]\Rightarrow x\leqslant \frac{17}{2}[/tex]
[tex]\Rightarrow x\leqslant 8 \frac{1}{2}[/tex]
As the number of donuts can only be a natural number.
Hence, the maximum number of donuts that Jervane can buy are 8.
look at the picture please

Select the reason why these triangles are
similar. If they are not, select "Not similar".
Α. ΑΑ
B. SAS
C. SSS
D. Not similar
Answer:
not similar
Step-by-step explanation:
similar means proportional
1, 1, and 0.5 are not proportional to 3.5, 3, and 2.25
As the two side lengths of the smaller triangle is the same but the ratio of those side in a larger triangle and the smaller triangle is different they are, D. Not similar.
What is congruency?We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.
We know two triangles are similar if the ratios of their corresponding sides are equal.
The larger triangle has sides 3, 3.5, and 2.25.
And the smaller triangle has sides 1, 1, 0.5.
As the smaller triangle has side lengths 1, 1, and the ratio of the sides of the larger triangle and the smaller triangle is (2 + 1)/1 and (2.5 + 1)/1 which is equal to 3/1 and 3.5/1 3 and 3.5 but the smaller side has 1 and 1, therefore, they are not similar.
